.NET Framework 4.5.2
OS: Windows Server 2012 RS Standard
IIS: 6.2
Application Pool: .NET CLR Version v.4.0.30319
Managed Pipeline Mode: Integrated
Spread.NET Version: 11.45.20183.0
NOTES:
The problem below ONLY occurs when hosted in IIS from our web-server. It does NOT occur when hosted through IIS Express (v.10.0.18362.1) on my local machine. I'm able to debug this problem while attaching to the running IIS process ID from Visual Studio on the web-server.
ISSUE:
We have some logic that checks for changes in the Datasource which has been bound to the FpSpread control. If changes are detected we then pull out the cell values where a delta exists. There are no problems with the code detecting changes; however, there is a problem with the result returned.
Example Code:
public static DataTable getUpdatedGrid(FpSpread FpExcel, DataTable beforeDt)
{
FpExcel.SaveChanges();
if (FpExcel.Columns.Count == beforeDt.Columns.Count)
{
// No added headers. HasChanges does not track added headers.
if (((DataSet)FpExcel.DataSource).HasChanges())
{
DataTable changes = ((DataSet)FpExcel.DataSource).GetChanges().Tables[0];
etc...
The code above works as expected, it detects the change and makes it to the "DataTable changes" statement. The only problem is the value doesn't reflect the change the user made if that change involved changing the case. For example if the user tries to change a cell from "Click" to "click" the "HasChanges" condition will evaluate to "true"; however, the value remains "Click."
Below is a screenshot where the user attempted to change a cell value from "False" to "false". As you can see the case was preserved and not altered.
Again this only happens when the user tries to change the case of the cell value. Changing the value to something completely new works as expected.
As mentioned prior this only happens when hosted in IIS. Also the dataset bound to the control has "CaseSensitive" set to "true", as noted in the screenshot below:
We found the cause and a solution. After looking at additional instances of published code it turns out that this issue is somewhat intermittent, but it seemed to be fairly consistent when cell values equal True or False.
In our solution we are doing a lot of cell formatting prior to binding. Part of this logic involved setting the CellType for all columns to TextCellType, example below.
TextCellType txt = new TextCellType();
txt.AllowWrap = false;
txt.Multiline = true;
FpExcel.Columns[0, FpExcel.Columns.Count - 1].CellType = txt;
This code works but it gave us the false assumption that this "type" wouldn't be overridden by any other logic.
Apparently this assumption turned out to be somewhat incorrect as it seems like cells with a certain value intermittently have their changes suppressed, as mentioned above with True/False. This lead us to the DataAutoCellTypes method, which by default is True. By setting DataAutoCellTypes to False, using the statement below, our issue disappeared.
FpExcel.Sheets[0].DataAutoCellTypes = false;

I'm currently developing a Visual Studio extension. For a new feature I need to find out whether a given ProjectItem (file) was modified (has "Pending Changes" since the last commit). For this I would like to query the source control provider.
I already tried searching all the properties of the ProjectItem but there is nothing hidden in there.
I also tried getting a service associated with source control from the Package.cs. I tried getting IVsSccManager2, IVsSccManager3 and IVsSccGlyphs. All return null (the test project is under source control). edit: I try to get these services by calling GetService(typeof(IVsSccManager2)) inside my Package.cs. The source control plugin of my debugging session correctly shows the changed files at the time this is called.
I can't seem to find anything online about this topic. How can I find out the modified state? Is it even possible?
After letting this topic sit for some time I recently came back to it and found the solution thanks to the help of my collegue. The problem was that I had no experience in bitwise comparison so I didn't know how to handle the response properly. Luckily my collegue gave me the right tip.
To interpret the result of status (thanks to #simon-mourier for the help on this code):
uint[] sccStatus = new uint[] { 0 };
if (VSConstants.S_OK == manager.GetSccGlyph(1, new[] { filePath }, new[] { VsStateIcon.STATEICON_NOSTATEICON }, sccStatus))
{
__SccStatus status = (__SccStatus)sccStatus[0];
}
One has to do bitwise comparison with the state of __SccStatus you are looking for, for example:
if ((sccStatus[0] & (uint)__SccStatus.SCC_STATUS_RESERVED_2) != 0)
return true;
The comparison returns true in case the state is set. If you need help on what specific state combinations can mean, just comment here and I can help on that.
I've noticed that when changes are made to the assemblyinfo.cs the hash that is used to generate the user settings path is changed.
The screen grab shows the two directories that were created when I changed the copyright date from 2014 to 2015.
I don't imagine I will change other items in the assemblyinfo, but I'm pretty sure I will change the copyright if I do another release next year.
What's the best way to handle this?
Thanks in advance.
The ApplicationSettings class has an Upgrade method which will move the existing setting values to the new settings file.
What I have done previously is to have a boolean flag as a setting (named something like UpgradeRequired) which indicates if an upgrade to the settings is required. This is set to true as default.
When the application starts, check this flag and call the Upgrade() method if required (and then set the UpgradeRequired setting to false).
if (Settings.Default.UpgradeRequired)
{
Settings.Default.Upgrade();
Settings.Default.UpgradeRequired = false;
Settings.Default.Save();
}
I am trying to create a UI test in VS 2010 using IE 9 in IE 8 compatibilty mode however when trying to record an action recording many of the steps fail. Then when I manually code in the missing steps and try to fill in a log in form with a username and password I get an exception that says I have failed to perform an action on hidden control.
The UI Test code:
public void Recordedmethod()
{
BrowserWindow uILogInWindowsInternetWindow = this.UILogInWindowsInternetWindow;
HtmlHyperlink uILogInHyperlink = this.UILogInWindowsInternetWindow.UIHomePageDocument.UILogInHyperlink;
HtmlEdit uIUsernameEdit = this.UILogInWindowsInternetWindow.UILogInDocument1.UIUsernameEdit;
HtmlEdit uIPasswordEdit = this.UILogInWindowsInternetWindow.UILogInDocument1.UIPasswordEdit;
#endregion
// Go to web page 'http://localhost:15856/WebSite1/'
uILogInWindowsInternetWindow.NavigateToUrl(new System.Uri(this.RecordedMethodParams.UILogInWindowsInternetWindowUrl));
// Set flag to allow play back to continue if non-essential actions fail. (For example, if a mouse hover action fails.)
Playback.PlaybackSettings.ContinueOnError = true;
// Mouse hover 'Log In' link at (1, 1)
Mouse.Click(uILogInHyperlink);
// Reset flag to ensure that play back stops if there is an error.
Playback.PlaybackSettings.ContinueOnError = false;
// Type 'test' in 'Username:' text box
uIUsernameEdit.Text = this.RecordedMethodParams.UIUsernameEditText;
// The following element is no longer available: IE web control; Process Id [6320], window handle [3168166]
// Type '********' in 'Password:' text box
uIPasswordEdit.Password = this.RecordedMethodParams.UIPasswordEditPassword;
// The following element is no longer available: IE web control; Process Id [6320], window handle [3168166]
}
This is an issue linked to an Internet Explorer patch that was released in September.
KB2870699
This affects VS2010 and VS2012.
Microsoft released a patch that corrects the issue for VS2012 (and I've confirmed that it fixed the issue for me).
http://blogs.msdn.com/b/visualstudioalm/archive/2013/09/17/coded-ui-mtm-issues-on-internet-explorer-with-kb2870699.aspx
Currently the only workaround for VS2010 is to uninstall the patch (KB2870699); however, as with any sort of security patch you'll want to consider carefully whether pulling it is safe to do given your situation.
EDIT: This was not a fun bug for me to deal with. I had just upgraded to VS2012 from VS2010 and all of a sudden I found none of my previously functioning CodedUI tests working. I assumed it was an issue with VS2012 and after banging my head against the wall for the better part of a day I found out it was an issue with a patch. It was just my luck that I upgraded to 2012 at the same time the patch had been installed on my system. Good times!
There is actually an updated for VS 2012 to fix this issue
http://blogs.msdn.com/b/visualstudioalm/archive/2013/09/17/coded-ui-mtm-issues-on-internet-explorer-with-kb2870699.aspx
Hope this helps!
I was having the same problem with my coded ui test. It's an issue with VS-2012 i guess, i tried every update (installing/uninstalling them and everything..) nothing worked.
I tried VS-2013 Ultimate and it worked.
You can use exception handling to capture the error while still not having the test failed.
The test is failing because at the time it performs click action, the control is hidden.
try
{
//your code goes here
}
catch(FailedToPerformActionOnHiddenControlException e)
{
Console.WriteLine(e.Message);
}
I have inherited an application that runs small reports locally using Microsoft Web ReportViewer. Our application allows you to "Preview/Print" a report by clicking on a specific button that routes the user to a URL that allows them to download the report as a PDF. We have recently received the requirement to save these PDFs to the document table in our database. I have been able to get this to work successfully on localhost; however, when I publish the application to our IIS server, I get the following error:
System.Data.SqlClient.SqlException: Login failed for user 'Domain\Servername$'.
I've reviewed all of the sites that I could find involving this error (including this one) - most point to adding the server account to the SQL database; however, this shouldn't be an issue, since the button to preview/print the document is still functional and works as expected when the application is published and all of the data is held in a local object, which was previously pulled from the database (the model parameter below). The button and the auto-generation feature use the same two methods to create the PDF document(see below).
Here's some code:
public static byte[] CreatePDFDocument(DocumentTemplateType template, Request model)
{
Warning[] warnings;
string[] streamIds;
string mimeType = string.Empty;
string encoding = string.Empty;
string extension = string.Empty;
ReportViewer viewer = new ReportViewer();
viewer.ProcessingMode = ProcessingMode.Local;
viewer.LocalReport.ReportEmbeddedResource = "Xxx.Xxx.Bll.ReportViewerRDLCs." + template.RdlcFilename;
switch ((DocumentType)template.DocumentTypeId)
{
case eDocumentType.Report1:
viewer.LocalReport.SetParameters(GetForm1Parameters(model));
break;
/**
* Several other reports are in this switch. All reports have the
* same issue - all but one are removed for brevity.
*/
}
byte[] bytes = viewer.LocalReport.Render("PDF", null, out mimeType, out encoding, out extension, out streamIds, out warnings);
return bytes;
//return new byte[5] {5,6,7,8,9}; - used for troubleshooting.
}
public static List<ReportParameter> GetReport1Parameters(Request model)
{
List<ReportParameter> rptParams = new List<ReportParameter>();
//Start comment
rptParams.Add(new ReportParameter("EmployeeFullName", string.Format("{0:NN}", model.Employee)));
rptParams.Add(new ReportParameter("EmployeePhoneNumber", string.Format("{0:(###) ###-####}", Convert.ToInt64(model.Employee.PhoneNumber))));
rptParams.Add(new ReportParameter("HrchyShortDesc", model.Employee.HrchyShortDesc));
rptParams.Add(new ReportParameter("RequestDate", model.RequestDate.ToShortDateString()));
rptParams.Add(new ReportParameter("RequestRequested", model.RequestRequestType));
rptParams.Add(new ReportParameter("ReasonForRequest", model.RequestRequestReason));
rptParams.Add(new ReportParameter("LogNumber", model.CaseId));
if (!string.IsNullOrWhiteSpace(model.TimeSensitiveReason)) rptParams.Add(new ReportParameter("TimeSensitiveReason", model.TimeSensitiveReason));
var lastAction = model.LastActionOfType(WorkflowStateActionType.EmployeeConfirmation);
if (lastAction != null)
{
rptParams.Add(new ReportParameter("TodaysDate", lastAction.ActionDate.ToShortDateString()));
rptParams.Add(new ReportParameter("EmpConfirmed", "true"));
}
else rptParams.Add(new ReportParameter("TodaysDate", DateTime.Now.ToShortDateString()));
//end comment
return rptParams;
}
Through a lot of commenting in and out and pushes to our server, I've deduced the following:
From what I can tell, the error occurs on calling GetReport1Parameters. In the code above, I included a start and end comment - I've commented out everything in between, leaving only the list initialization and return statement (of an empty list) and still received the error.
I've commented out the call to GetReport1Parameters and returned a nonsensical byte array and didn't receive an Exception.
All functionality works fine on localhost and when I step through the functions, all of the variables seem to appear normal.
Things I've tried to do to remedy the situation:
1. Removed connection strings from the app.config, so that the application has to go to the web.config to get the correct strings (even though they were the same).
2. Commented in and out different sections of code to determine the problem area.
3. Tried calling the GetReport1Parameters method and returning null, leading to a null reference exception.
4. Tried calling the GetReport1Parameters with an empty parameter list, leading to the error mentioned above.
5. Tried running the report with no parameters (not even a blank list), got a ReportProcessingException for missing params.
Some additional information:
We use a service account for the application using impersonate identity in the web.config. That line is commented out on localhost, but is running on IIS.
All of other database interaction works correctly.
All of our database interaction is done using LINQ to SQL - model is an object based off of a database table, with some additional information that is calculated dynamically.
My desired outcome is that both the autogenerated documents and the preview/print documents both work. I have a feeling that this may be something simple that I'm overlooking, but I've already spent several hours today trying to fix this.
I can't think of any other pertinent information, but if you have questions I'll be more than happy to answer them.
Edit: Additional attempts to find solution:
Tried setting LINQ Deferred Loading equal to false. This caused more problems than it solved.
Implemented IReportServerCredentials and assigned the ReportViewer's ServerReport.ReportServerCredentials with the correct database credentials.
Assigned all pertinent report parameters to a Dictionary, and then called .ToString() on every object to ensure that it is pulled from the database. Then assigned those strings from the dictionary to the report parameters, so that ReportViewer should be receiving the data from the string pool, as opposed to pulling it from the database.
Even though you are using an ObjectDataSource to pass data to your report, Report Viewer will still invoke the Select method, which in turn could cause database access to occur. So even though it may seem that the login is unnecessary, you would need to dig into the data access methods you supplied with your ObjectDataSource to know for sure.
The error you are getting is being caused by a bug in Report Viewer 2010 that is describe in the following Microsoft Connect article:
ReportViewer.LocalReport.Render and ReportViewer.LocalReport.SetParameters changes ImpersonationLevel to None
Although the article mentions this problem should be fixed in Service Pack 1, it does not appear to be the case. I have not verified if this problem is fixed in Report Viewer 2012.
I worked around the problem by changing my data access layer to compare the current identity against the one in my HttpContext and restore it if necessary using the following code snippet:
System.Security.Principal.IIdentity id = System.Web.HttpContext.Current.User.Identity
if (id.Name != System.Security.Principal.WindowsIdentity.GetCurrent().Name)
{
context = (id as System.Security.Principal.WindowsIdentity).Impersonate()
}
I do this right before I connect to the database and undo it as soon as the connection is open.
I am not exactly thrilled with this workaround, mainly because now my data access layer is referencing the UI layer (System.Web).
I've written a sharepoint application that needs to change web.config
I have a feature that is supposed to make all these configurations. The code for that feature is like this:
SPSite site = properties.Feature.Parent as SPSite;
List<SPWebConfigModification> modifications = new List<SPWebConfigModification>();
modifications.AddRange(CustomErrorsModeConfig.Modifications);
webConfigModificationHelper.AddWebConfigModifications(site.WebApplication, modifications);
CustomErrorsModeConfig.Modifications property contains this code:
public static SPWebConfigModification[] Modifications = {
new SPWebConfigModification()
{
Owner = WebConfigModificationOwner,
Name = "mode",
Type = SPWebConfigModification.SPWebConfigModificationType.EnsureAttribute,
Path = "system.web/customErrors",
Sequence = 0,
Value = "Off"
}
};
Then finally the webConfigModificationHelper.AddWebConfigModifications method:
foreach (SPWebConfigModification modification in modifications)
{
webApp.WebConfigModifications.Add(modification);
}
webApp.Farm.Services.GetValue<SPWebService>().ApplyWebConfigModifications();
webApp.Update();
The problem is that I keep getting this error:
Name cannot begin with the ''' character, hexadecimal value 0x27. Line 1, position 1453
Could this be a problem with the web.config before I try to apply my changes ?
Could the SPWebConfigModification property be incorrectly defined ?
Is there some glitch in my code that leads to this error ?
Might there be some property I am missing (e.g. web.AllowUnsafeUpdates) ?
Some sharepoint site configuration ?
I've been trying to solve this issue for some time now with no luck :( Any ideas ?
I can recommend using stsadmwebconfig for making changes to web.config files. I've implemented this in many features and it has always been a pain, especially while developing. Using this tool makes it a lot easier.
Ive seen this before when the file format is not correctly set between the file and the declaration.
Open the web.config file into a advanced text editor (Notepad++ or Visual Studio) and manually force the file type to match what is specified. Usually its going to be UTF-8.

Try taking the List template and for loop out and set the property using straightforward syntax. Here's a post for setting the property in your example, see if you can get this to work and then progress to building up a more generic solution with a List and iteration over the items in the list.
