In Sitecore, getting the rendering using context.Parameters["renderingId"] and GetItem

I have multiple renderings and I'm adding a help button to the Custom Experience Toolbar for each one that opens a new window and jumps to a specific anchor in the help file. I want the anchor to match the name of rendering such as "Container" or "Event List". So I made a custom command and I'm trying to get to the rendering item using this method but for some reason targetItem is always null. What am I doing wrong?
public class Help : Command
{
public override void Execute(CommandContext context)
{
Assert.ArgumentNotNull(context, "context");
Assert.IsNotNull(context.Items, "context items are null");
Assert.IsTrue(context.Items.Length > 0, "context items length is 0");
StringBuilder data = new StringBuilder();
var renderId = context.Parameters["renderingId"];
if (Sitecore.Data.ID.IsID(renderId))
{
Sitecore.Data.Items.Item targetItem =
Sitecore.Context.Database.GetItem(renderId);
if (targetItem != null) //never gets the item for me to access it's properties
{
data.Append("Rendering Name: " + targetItem.ToString() + "\r\n");
data.Append("Rendering Display name: " + targetItem.Name + "\r\n");
}
}
}
}

yes, whenever you do any operation on any sitecore admin site, you will always get a core database as a content database, so in order to get your thing working you have to first set your database as master, then you can use getItem method for retrieving the Item and its renderings.
Happy coding!!

can't get the body/attachments of new mails in outlook

I've developed an Outlook plugin using C# where for each new mail received, i get(and save) the sender/subject/the body of email & the attachments. Well, the last 2 gave me a headache. I can see the sender and the subject of the new mail but for the body&attachments it seems that is a problem. I've used NewMailEx for getting the new mails in Inbox. The function looks like this:
private void Application_NewMailEx(string EntryIDCollection)
{
string[] entryIdArray = EntryIDCollection.Split(',');
foreach (string entryId in entryIdArray)
{
try
{
Outlook.MailItem item = (Outlook.MailItem)Application.Session.GetItemFromID(EntryIDCollection, null);
string subj = item.Subject; //works
string to = item.To; //works
string bec = item.BCC; //does not work but dont care
string body = item.Body; //DOES NOT SAVE THE BODY OF THE NEW MAIL RECEIVED
string final = "Sender: " + item.SenderEmailAddress + "\r\n" + "Subject: " + subj + "\r\n" + "BCC: " + bec + "\r\n" + "TO: " + to + "\r\n\n" + "Body: " + body + "\r\n\n";
System.IO.File.AppendAllText(#"D:\tmp\atr.txt", final);
//the result of item.attachments.count is always 0 , even though I've
//sent mails with a different number of attachments. So the if
//statement is false
if (item.Attachments.Count > 0)
{
for (int i = 1; i <= item.Attachments.Count; i++)
{
item.Attachments[i].SaveAsFile(#"D:\tmp\" + item.Attachments[i].FileName);
}
}
Marshal.ReleaseComObject(item);
}
catch (System.Exception e)
{
MessageBox.Show(e.Message);
}
}
}

Where does the Item variable come from? You need to initialize it using Application.Session.getItemfromID().

I'm writing in VBA, so I feel like posting my code here would be a faux pas, but I have come to a solution using similar Object Libraries from the Outlook application that I think transfer well to your C++ intentions.
First of all, switching to POP3 certainly fixes this problem, but you're stuck using POP3, which is only ideal from a programming standpoint.
The solution I have found follows this algorithm:
//Generate Outlook MailItem Object, "item"
//If item.DownloadState is not 1,
//item.Display
//item.Close(1)
//Perform end of code operations
//Call Function that is identical to Application_NewMailEx but is not Application_NewMailEx because Application_NewMailEx is a function that is thrown during the incoming mail event.
//Else,
//Perform Intended Code
You see how calling a function identical to Application_NewMailEx creates a kind of loop because if item.DownloadState is not 1, you'll be calling that function again? I get that this isn't the most ideal coding practice, but I have scoured the internet and Outlook Application and Outlook Object Library experts have no idea how to solve this problem any other way (in fact, no one even proposes THIS solution)

Debugging: Microsoft JScript runtime error

I am desperately in need of debugging help, been stuck at this error for 6 days now.....
the error I get in my ASp.net app is :
Microsoft JScript runtime error: Sys.WebForms.PageRequestManagerParserErrorException: The message received from the server could not be parsed. Common causes for this error are when the response is modified by calls to Response.Write(), response filters, HttpModules, or server trace is enabled.
Details: Error parsing near '<script type='text/j'.
Below is the relevant code snippet,
CollyDataExchangeWebService Col_ValSub = new CollyDataExchangeWebService();
CollyReportServiceRequest ServiceReq = new CollyReportServiceRequest();
CollyReportServiceRequestData ServiceReqData = new CollyReportServiceRequestData();
ServiceReqData.AmendmentIndicatorSpecified = true;
ServiceReqData.AmendmentIndicator = false;
ServiceReqData.CollyReport = ColRep;
ServiceReq.ServiceRequestData = ServiceReqData;
ServiceReq.ServiceRequestHeader = ServiceHeader;
errValidate = null;
//btnOK.OnClientClick = "MSGShow()";
bool Valid = true;
string ErrMsgs = "";
if (((System.Web.UI.WebControls.Button)(sender)).CommandArgument == "Validate")
{
CollyReportServiceResponse ValResponse = Col_ValSub.validateReport(ServiceReq);
switch (ValResponse.ServiceResponseHeader.ServiceStatus)
{
case ServiceStatus.Successful:
btnOK.OnClientClick = "";
valHeader.Text = "Validation is Completed. No errors were found";
mlValPopup.Show();
break;
case ServiceStatus.ValidationErrors:
Valid = false;
ErrMsgs = ErrMsgs + _ValidationError(ValResponse);
ValBTN.Update();
mlValPopup.Show();
break;
case ServiceStatus.SystemError:
btnOK.OnClientClick = "";
Valid = false;
ErrMsgs = ErrMsgs + _SystemError(ValResponse);
ValBTN.Update();
mlValPopup.Show();
break;
}
After hours of debugging I found this line to be causing the error:
CollyReportServiceResponse ValResponse = Col_ValSub.validateReport(ServiceReq);
After 6 days of debugging and frustration I found that SOME records cause this issue and others dont in OLDER versions of the code but in new version ALL of the records lead to this error so it has to do something with the data in the DB which means SOME method in the code behaves differently to nulls but I cant find out exactly what the issue is because my app is 30k lines of code
after searching around and trying various solutions, the below 2 are not the solutions to my issue.
forums.asp.net/t/1357862.aspx
http://www.vbforums.com/showthread.php?t=656246
I want to mention that I am already having a difficult time dealing with this application because it was written by other programmers that are now long gone leaving behind non-documented or commented spaghetti code.
I did not code this but other programmers from past have put Response.Write in code:
private void MessageBox(string msg)
{
if (!string.IsNullOrEmpty(msg))
{
Global.tmpmsg = msg;
msg = null;
}
Response.Write("<script type=\"text/javascript\" language=\"javascript\">");
Response.Write("window.open('ErrorPage.aspx?msg=" + "','PopUp','screenX=0,screenY=0,width=700,height=340,resizable=1,status=no,scrollbars=yes,toolbars=no');");
Response.Write("</script>");
}
This one is in another method:
Response.Write("<script type=\"text/javascript\" language=\"javascript\">");
Response.Write("alert('No search resuls were found');");
Response.Write("</script>");
Or This:
if (!string.IsNullOrEmpty(msg))
{
Global.tmpmsg = msg;
Response.Write("<script type=\"text/javascript\" language=\"javascript\">");
Response.Write("window.open('ErrorPage.aspx?msg=" + "','PopUp','screenX=0,screenY=0,width=700,height=340,resizable=1,status=no,scrollbars=yes,toolbars=no');");
Response.Write("</script>");
}
After Jrummel`s comment I added this to code and then nothing at all happened.
private void MessageBox(string msg)
{/*
if (!string.IsNullOrEmpty(msg))
{
Global.tmpmsg = msg;
msg = null;
}
Response.Write("<script type=\"text/javascript\" language=\"javascript\">");
Response.Write("window.open('ErrorPage.aspx?msg=" + "','PopUp','screenX=0,screenY=0,width=700,height=340,resizable=1,status=no,scrollbars=yes,toolbars=no');");
Response.Write("</script>");
*/
// Define the name and type of the client scripts on the page.
String csname1 = "PopupScript";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, csname1))
{
String cstext1 = "<script type=\"text/javascript\" language=\"javascript\">" + " " + "window.open('ErrorPage.aspx?msg=" + "','PopUp','screenX=0,screenY=0,width=700,height=340,resizable=1,status=no,scrollbars=yes,toolbars=no');" + " " + "</script>";
cs.RegisterStartupScript(cstype, csname1, cstext1, false);
}
}

I have found the error after 2 weeks of debugging and 2 days of Brute Forcing:
In one of the 800 DB columns that I have there was a null/improper value. This value reacted with one of the 150 methods in my ASP.NET code in such a way as to present a JavaScript error even though Response.Write() was NOT the issue. I have not found which method it was that reacted to this value but I have found the solution which is to simply input a valid value on the column record..
How a programmer can brute force to find the issue:
In my case after long days of debugging I took a sample of one working record and another sample of an error leading record. Once I had achieved this, I used
DELETE FROM tablename WHERE UniqueColID= unique identifier for the error causing record
Then I did:
INSERT INTO tablename ([uniqueIdentifier],[ column 2],[column 3]) SELECT #UniqueIdentifierofErrorCausingRecord, column2, [column3] FROM TableName WHERE [uniqueIdentifier]=#UniqueIdentifierForWorkingRecord;
What the first statement does is delete the non working record then the 2nd statement reinserts that record with identical column values of the working record but with the UniqueIdentifier of the Non working record. This way I can go through each table to find which table is causing the error and then I can pinpoint which column of that table is the issue.
The specific issue in my case was DateTime.TryParse() because a table column value was inserted in improper format.. The code performed field population in one of the methods without a try and catch using the DateTime.Parse method.... After some testing it seems even a try/catch is not able to pick this error up as it is a javascript error..

Don't use Response.Write().
Instead, create a LiteralControl and add it to the page.
Use ClientScriptManager to add scripts to the page. Here's an example from MSDN:
// Define the name and type of the client scripts on the page.
String csname1 = "PopupScript";
Type cstype = this.GetType();
// Get a ClientScriptManager reference from the Page class.
ClientScriptManager cs = Page.ClientScript;
// Check to see if the startup script is already registered.
if (!cs.IsStartupScriptRegistered(cstype, csname1))
{
String cstext1 = "alert('Hello World');";
cs.RegisterStartupScript(cstype, csname1, cstext1, true);
}

Big websites not loading at all - error

I have created a web browser for windows phone 7. In that am saving the history of browsing also with title of that page. But due to this codes when i tried to load a somewhat big website like thinkdigit,etc. are not loading. At the same time if i delete that particular codes then no history is being recorded in the history page. It shows error for the below highlighted code - "An unknown error has occurred. Error: 80020006". I think its due to big site or else do i need to put milliseconds or what i have to do???
Thanks in advance for your hard work!!!
Below is the codes i have used for it-
private void browsers_Navigated(object sender,System.Windows.Navigation.NavigationEventArgs e)
{
pbarWebClient.Visibility = System.Windows.Visibility.Collapsed;
if (!fromHistory)
{
if (HistoryStack_Index < HistoryStack.Count)
{
HistoryStack.RemoveRange(HistoryStack_Index, HistoryStack.Count - HistoryStack_Index);
}
HistoryStack.Add(e.Uri);
if (!app.incognito)
{
********string title = (string)browsers[this.currentIndex].InvokeScript("eval", "document.title.toString()");********----->This is the error.
stream.WriteLine(title + ";" + e.Uri.ToString());
}
HistoryStack_Index += 1;
}
fromHistory = false;
navigationcancelled = false;
Stop.Visibility = Visibility.Collapsed;
}

I would expect that eval has been overridden or in some other way suppressed on the site(s) in question.
"80020006" is a javascript invocation error code. Simply assuming that a javascript method will be available and work in the same way on any site is not always going to be true.

Finally i got the suitable answer for my own question. Just replace the above codes with this-
if (!app.incognito)
{
Thread.Sleep(100);
Dispatcher.BeginInvoke(() =>
{
string title = (string)browsers[this.currentIndex].InvokeScript("eval", "document.title.toString()");
stream.WriteLine(title + ";" + e.Uri.ToString());
});
}

Script not working when called from .cs file

I am tryong to do the following in a Row_Command event of a gridview. But the the pop up box never comes up, I have tried it in so many different ways.. but yet no luck. Please if someone can see the issue i would really appreciate a pointer.
protected void Gridview_RowCommand(object sender, GridViewCommandEventArgs e)
{
if(e.CommandName == "Merchant")
{
if (ItemsAvailable)
{
StringBuilder sb = new StringBuilder();
MyClass class = new MyClass();
TList<LineItems> otherItems = MyClass.GetItems(id);
bool IsNotAvailable = false;
foreach (LineItems item in otherItems)
{
Merchandise skuMerchandise = skuMerchandise.GetMerchandise(otherItems.mid);
if (skuMerchandise != null)
{
if (skuMerchandise.AvailableItems <= 0)
{
sb.Append(OtherItems.Name);
sb.Append(Environment.NewLine);
IsNotAvailable = true;
}
}
}
if (IsNotAvailable)
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "key",
"function Redirect() {location.href = 'homePage.aspx';}
if(confirm('The items : "+sb.ToString()+" will arrive in 1 month.
Do you wish to continue?') == true){Redirect();};", true);
}
}
}
Everytime i click the button, it just passes like nothing.. never prompts eveb though IsNotAvailable is true when I add a breakpoint.

You can go for a simpler way,
Define the javascript function in the design/separate script file so that it accepts the name of item. eg. myFunction(itemName)
And in your CS file, simply add a call to that function,
if (IsNotAvailable)
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "key",
"myFunction('" + itemName + "')
}
}
It will make things simpler and you would be able to confirm if this is a Javascript issue or a problem in how you are writing it through CS file.
Update:
Your first goal should be to make sure that your JS function is working for you, so before anything, add the following code in an empty html file and run it,
<script type='text/javascript'>
ItemNotInStock('item');
function ItemNotInStock(itemName)
{
var message = "The following items are no longer in stock :" + itemName + ".
Would you like to continue?";
if (confirm(message) == true)
{ location.href = "homePage.aspx"; }
}
If you redirect correctly then do what's mentioned below.
Define the following javascript in your design file(tested it locally, working for me in chrome,)
<script type='text/javascript'>
function ItemNotInStock(itemName)
{
var message = "The following items are no longer in stock :" + itemName + ".
Would you like to continue?";
if (confirm(message) == true)
{ location.href = "homePage.aspx"; }
}
In your C# code, add following line
if (IsNotAvailable)
{
Page.ClientScript.RegisterClientScriptBlock(this.GetType(), "key",
string.Format("ItemNotInStock('{0}');", itemName);
}
}

Make sure your JavaScript code is executed by using breakpoints available in the developer tools of the browser of your choice, like Chrome Developer Tools: Breakpoints
BTW: Why do you create an instance of Merchandise if you instantly discard it with the next line?
