MPF for Projects - Visual Studio 2010

New Post: VisualStudio Source Code (Text) editor cannot edit

amerthebest — Wed, 17 Apr 2013 13:52:57 GMT

Hi,
I've created standalone shell isolated based on VS 2010 SP1 and using MPF for project factory support.

Now, when i open Code/Text editor i cannot change its content, i can Copy and Paste in another file outside of VS shell but not in the editor.

Any thoughts?

Thanks

New Post: DebugEngine InvalidCastException.

SimonGates — Tue, 19 Feb 2013 16:25:25 GMT

Hi,

I maintain a VS plugin, with associated debug engine written using the MPF.

I have just implemented a disassembler module for it, but when selecting a disassembler window I get the following Exception:

An unhandled exception is about to terminate the process. Exception info:
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.InvalidCastException: Unable to cast object of type 'MyCoLtd.MyPackage.CodeContext' to type 'Microsoft.VisualStudio.Debugger.Interop.IDebugCodeContext2'.

at Microsoft.VisualStudio.Platform.WindowManagement.WindowFrame.OnContentShowing(View view)
at Microsoft.VisualStudio.Platform.WindowManagement.WindowManagerService.OnViewContentShowing(Object sender, ViewEventArgs args)

The C# code for the class that VS fails to cast is:

    [ComVisible(true)]
    [Guid(GuidList.guidCodeContextString)]
    public class CodeContext : Microsoft.VisualStudio.Debugger.Interop.IDebugCodeContext2, MemoryContext
    {
        /* implementation */
    }

Given that the CodeContext class is used elsewhere without problem and it's not even reaching the new disassembler code, I'm somewhat stuck as to what to do.

Any suggestions where the problem might be?

Thanks,

Simon.

Created Issue: Folder defined in project templates will not be created physically [12521]

humbrie — Wed, 24 Oct 2012 11:05:23 GMT

Folder (and their contents) will not get created, if they are defined in a vstemplate (project). Instead i had to overwrite the CreateFolderNode method in class ProjectNode.

But the FolderNotes appear in the Solution Explorer. In fact, they are degraded to some kind of solution folder.

If an item got dragged or added to the FolderItem, the folder will be created ad hoc.

Commented Issue: Project reference doesn't work correctly if referenced project is in a solution folder [10801]

ldubois — Wed, 29 Aug 2012 00:31:12 GMT

1. Create a Solution folder
3. Create a C# project inside the just created folder.
4. Create a whatever project using MPF (Visual T# in the attached Image)
5. Make a reference from MPF project to C# project: an exclamation sign appears. Reference is not resolved and Intellisense does not work!

See attached image.

@kiquenet, this is a method provided by MPF that compare two paths and returns true iif they are equal.

New Post: Build project created by CustomProject sample throws Microsoft.Build.Exceptions.InvalidProjectFileException - Cannot evaluate the item metadata "%(FullPath)" - ErrorCode=MSB4023

hieptang — Fri, 27 Jul 2012 08:13:08 GMT

Hi,

I've trying to create a project based on template from CustomProject sample and I meet an InvalidProjectFileException when trying to Build this project.

Please help me on this problem. This issue happened on Visual 2010, 2011 Beta and 2012 RC.

Here are my steps (run on Debug Mode):

- Open CustomProject on Samples folder.

- Build and Start Debug

- On a new Visual Studio (debug extension), try to create a new project with My Custom Project template

- After project created and load successful on Solution Explorer, try Build Project

The Exception is throwned:

It's unclear from your question whether this is actually presenting a problem to you, or if it's just something you're wondering if it's a problem.

This is actually expected behavior. The MSDN documentation for this method prescribes that any unsupported property throw an ArgumentException. So while it's not ideal that when the debugger is attached it can raise all these exceptions which look like errors when in fact they are not, it's by design, and you can ignore them.

Commented Issue: ProjectConfig.get_CanonicalName returns display name instead of the canonical name [12178]

dinov — Tue, 22 May 2012 22:55:34 GMT

DisplayName is documented as being in the form "<configname>|<platform name>" http://msdn.microsoft.com/en-us/library/bb139670(v=VS.80).aspx

CanonicalName is just the config name such as "Debug" or "Release" http://msdn.microsoft.com/en-us/library/microsoft.visualstudio.shell.interop.ivsprojectcfg.get_canonicalname(v=VS.80).aspx

In MPFProj get_CanonicalName just calls get_DisplayName, so a string such as "Debug|AnyCPU" is passed out when it should just be "Debug".

The fix is to make get_CanonicalName just to do:

public virtual int get_CanonicalName(out string name)
{
name = configName;
return VSConstants.S_OK;
}

If you are using MPFProj w/ Dev11 and are getting an error about x64 and ARM targets not being supported in the WPF designer you might want this fix.

New Post: NDepend crashes the sample projects

piliev — Tue, 07 Feb 2012 17:32:37 GMT

Hi,

I'm trying to create a custom project type (started from the CustomProject sample) and it appears that when NDepend is active right clicking a folder crashes Visual Studio. The exception is StackOverFlowException and what happens is that something is calling the Collection property of OAFolderItem and then Caption of the folder endlessly.

Any idea where to start from in order to prevent this?

Commented Issue: Adding a folder when the folder already exists differs from C# [11519]

KlausGuetter — Fri, 13 Jan 2012 07:57:48 GMT

Select a folder, Project->New Folder, type in a folder name that exists on disk but not in the project system.

In MPFProj this reports an error that the folder already exists.

In C# this adds the existing folder.

The difference here is that MPFProj always immediately adds the folder including attempting to create the directory. The C# project system waits until the call to SetEditLabel to actually do the work of creating the directory and doesn't care if it already exists.
Comments: ** Comment from web user: KlausGuetter **

The proposed fix has a problem with subordinate folders: the VirtualNodeName is set wrong in this case which leads to the problem that files added to the new subordinate folder A\B\C end up in projectdir\C.

To fix, replace the line
this.VirtualFolderName = filename;
by
this.VirtualFolderName = Path.Combine(Parent.VirtualFolderName, filename);
in FinishFolderAdd

Created Issue: Copy and pasting a folder with multiple items throws an exception (WalkSourceProjectAndAdd adds item to incorrect parent) [11618]

dinov — Thu, 12 Jan 2012 21:05:56 GMT

ProjectNode.CopyPaste contains the following code to recursively add all of the siblings when copying a folder within a project:

// Then look at siblings
currentItemID = itemId;
while(currentItemID != VSConstants.VSITEMID_NIL)
{
variant = null;
ErrorHandler.ThrowOnFailure(sourceHierarchy.GetProperty(itemId, (int)__VSHPROPID.VSHPROPID_NextVisibleSibling, out variant));
currentItemID = (uint)(int)variant;
WalkSourceProjectAndAdd(sourceHierarchy, currentItemID, targetNode, true);
}

But to properly walk the list of siblings it needs to pass currentItemId to sourceHierarchy.GetProperty instead of passing itemId. By passing itemId it is repeatedly adding the same node multiple times. Ultimately this results in AddItemWithSpecific returning ADDRESULT_Cancel because of this check:

// If the file to be added is an existing file part of the hierarchy then continue.
if (NativeMethods.IsSamePath(file, newFileName))
{
result[0] = VSADDRESULT.ADDRESULT_Cancel;
continue;
}

And then AddNodeIfTargetExistInStorage throws an Exception with no message which propagates out to the user.

Changing to itemId to currentItemId causes the copy and paste to succeed.

New Post: IProjectionBuffer usage

jakub — Thu, 22 Dec 2011 15:50:23 GMT

hi,

we would like to make use of projection buffer, to mix several built-in languages within our file type.

MSDN documentation is very pure for any tutorials, and we can't figure out how to use it. We have an integration built on MPF10.

Can we get any hint or code sample? would be appreciated.

Thanks!
