I am using StringTemplate in c# and following code to load a template from a subdirectory of my application.
StringTemplateGroup group = new StringTemplateGroup("myGroup", "/tmp");
StringTemplate query = group.GetInstanceOf("Sample");
query.SetAttribute("column", "name");
Console.WriteLine(query);
I have a template file Sample.st in the tmp directory of my application.
I am getting the following error.
Unhandled Exception:
System.ArgumentException: Can't find
template Sample.st; group hierarchy is
[myGroup]
Does anyone know what is wrong here?
Probably you should specify absolute path as a second parameter for StringTemplateGroup constructor?
In addition to adding a reference to the Antlr3.StringTemplate assembly, you ALSO need to add a reference to the Antlr3.Runtime assembly (not necessarily the Antlr3.Runtime.Debug assembly, although this would also work). This worked for me.

Is there a way to find out the assembly name at design-time (i.e. not using reflection or runtime APIs such as System.Reflection.Assembly.GetEntryAssembly) from within Visual Studio?
The scenario requires a tool to get the assembly name that a Visual Studio project will eventually compile into.
This is like parsing the AssemblyName property of the .csproj - I am wondering if there are any APIs that can give this information reliably.
Please do not respond back with runtime APIs that use reflection - there is no assembly file present at the time I need the assembly name - just the metadata of the assembly in the csproj file.
if you are calling the tool via a post/pre-build event, this data is very easy to access.
Just go to the "project properties->Build Events" tab, then select either "edit pre-build" or "edit post-build", depending on when you want the tool to run. This should bring up an edit window with the ever helpful "Macros >>" button. Press this and you will be given a heap of macros to use and should be pretty much everything you need.
The "API" you could use is LINQ to XML after all the .csproj file is just xml. (and you can get the location of the .csproj file if you need from the solution file which for some reason is not XML but can be easily parsed)
You can use "TargetName" available in Macros for Post-build events. It will give you the assembly name for your project.
After a quick run through MSDN I found this article which might be a good start for some further research:
Accessing Project Type Specific Project, Project Item, and Configuration Properties
I think you will need to write some regular expression that will give you the value of "AssemblyTitle" attribute in AssemblyInfo.cs file.
Something like this:
public class Assembly
{
public static string GetTitle (string fileFullName) {
var contents = File.ReadAllText (fileFullName); //may raise exception if file doesn't exist
//regex string is: AssemblyTitle\x20*\(\x20*"(?<Title>.*)"\x20*\)
//loading from settings because it is annoying to type it in editor
var reg = new Regex (Settings.Default.Expression);
var match = reg.Match (contents);
var titleGroup = match.Groups["Title"];
return (match.Success && titleGroup.Success) ? titleGroup.Value : String.Empty;
}
}
I'm having a few troubles with getting resources dynamically as I get "Missing manifest" errors. I looked up a few possible causes and did what was written there but so far nothing worked.
Currently I have this situation:
The resx file I'm trying to access is: "Resources/Messages.resx" (thus in a nonstandard folder.
The code I'm using is this:
ResourceManager resourceManager = new ResourceManager("Resources.Messages", this.GetType().Assembly);
resourceManager.GetString("ResourceText" + MessageType + "Subject")
with messageType being a string. On the second line I get the error message.
The status of the resource file is this:
Build Aciton: Embedded Resource
Custom Tool: PublicResXFileCodeGenerator
Access Modifier Public
The resfile has 2 variants: Messages.res and Messages.de.resx with the same names for each row and also the same general properties (the "GetString" also definitively tries to access the correct name).
So my question is what I'm doing wrong there and what can I do to correct this problem?
Found the problem. For new ResourceManager not only the namespace of the resourcesfiles has to be given but also the default namespace. Thus if the application has a default namespace of: MyApplication.MyServerApp then instead of "Resources.Messages" one must put in: "MyApplication.MyServerApp.Resources.Messages" leading to the following functioning sourcecode:
ResourceManager resourceManager = new ResourceManager("MyApplication.MyServerApp.Resources.Messages", this.GetType().Assembly);
resourceManager.GetString("ResourceText" + MessageType + "Subject")
I am currently saving my .NET FX 4.0.1 StateMachine activity like this:
var sb = new StringBuilder();
var xamlWriter = ActivityXamlServices.CreateBuilderWriter(
new XamlXmlWriter(new StringWriter(sb),
new XamlSchemaContext()));
XamlServices.Save(xamlWriter, activityBuilder);
return sb.ToString();
This works fine and the generated XAML looks good. Unfortunately, it is invalid. I can read it back in using ActivityXamlServices.Load but when I execute it, it says that it doesn't know the properties defined in the workflow. Opening it in the Visual Studio designer yields the same errors:
Compiler error(s) encountered processing expression "ActiveCall". "ActiveCall" is not declared. It may be inaccessible due to its protection level.
Through comparing the original XAML with the XAML produced by my code, I found out how to fix this problem. I have to have this tag before the StateMachine tag:
<mva:VisualBasic.Settings>
Assembly references and imported namespaces for internal implementation
</mva:VisualBasic.Settings>
By the way:
The text inside the tag must be exactly like this, otherwise there will be an error when opening the WF in VS:
Failed to create a 'Settings' from the text 'FooBar'
Question:
What do I have to change in my code to have this tag in the generated XAML?
I think I found the answer.
I have to use the following code before calling Save:
VisualBasic.SetSettings(activityBuilder, new VisualBasicSettings());
If the activityBuilder has been created from a DynamicActivity it is even better to use the following code:
VisualBasic.SetSettings(activityBuilder,
VisualBasic.GetSettings(dynamicActivity));
If this is not used, namespaces that are only needed for extension methods are not written to the XAML and will lead to an error when loading and executing the XAML.
I summarized my findings on code project.
Could anyone give me an example of how to programatically add a property to an existing document type in Umbraco CMS? This is what I tried:
var dt = DocumentType.GetByAlias("TestDocType");
dt.AddPropertyType(new DataTypeDefinition(-49),"testprop", "test prop");
But it throws an exception:
Method not found: 'Void umbraco.cms.businesslogic.ContentType.AddPropertyType(umbraco.cms.businesslogic.datatype.DataTypeDefinition, System.String, System.String)'.
Any ideas?
I managed to fix it. The website was recently upgraded from Umbraco 4.5 to Umbraco 4.7.1, so the dll's had to be replaced with the more recent ones. In the older version of Umbraco the method's return type was public void AddPropertyType whereas the new one public PropertyType AddPropertyType. Apparently during the upgrade the new cms.dll wasn't copied over, so I copied it from a clean Umbraco 4.7.1 solution, changed the code to receive the return type and it helped.
Required namespaces:
using umbraco.cms.businesslogic.datatype;
using umbraco.cms.businesslogic.web;
So the final code(assuming correct assemblies are referenced):
var dt = DocumentType.GetByAlias("TestDocType");
var pType = dt.AddPropertyType(new DataTypeDefinition(-49),"testprop", "test prop");
That code looks fine to me, it should work.
Make sure your first line is actually returning a documentype, not null.
Also, do you have the proper 'usings' in place, you'll need at least some of these?
using umbraco.cms.businesslogic.web;
using umbraco.NodeFactory;
using umbraco.cms.businesslogic.member;
using umbraco.cms.businesslogic.datatype;
I am trying to access my local resources file in my code-behind. I did some googling since I was unsure of how to do it and found this:
oContent.Text = HttpContext.GetLocalResourceObject("NonSupport").ToString();
However, I get an error saying that it needs at least two parameters: VirtualPath and ResourceKey. There is a third, CultureInfo but that one is optional. When I put this in as my virtual path:
HttpContext.GetLocalResourceObject("App_LocalResources/ExpandableListView.aspx.resx", "NonSupport").ToString();
I get the following compiler error message:
The relative virtual path 'App_LocalResources/ExpandableListView.aspx.resx' is not allowed here.
I must be doing something wrong with this since my searches (and some posts I found on here) say all I need to do is call the resource key.
Any thoughts? Thanks!
Did you put a resource file with the name (your aspx web page).aspx.resx into a App_LocalResource folder underneath the path where your ASPX page lives??
Furthermore, just simply call the GetLocalResourceObject method on your current page:
oContent.Text = GetLocalResourceObject("NonSupport").ToString();
No need to use HttpContext for that - the method is defined on the Page class.
