Re: ImageList - MissingMainfest exception - C# Discussion Boards

OK, I can see the resx file now, and it's an embedded resource, so it must be in there.

I've inherited this project, the only form in which I have the bitmaps is this project file, where they are embedded in the imageList, with the obvious exception that I cannot get them out. How do I go about turning the list into a collection of bitmaps so I can load them into an image list manually ? Or, preferably, how can I make this code work as it stands ?

If I look at the XML, I can see the image stream there. I've tried all sorts of variations in the path I pass in to the resource object. Is there a way I can query it to find out the path I need ?

Thanks for your help.

The resources object is created like this:
System.Resources.ResourceManager resources = new System.Resources.ResourceManager("DetailsActions", System.Reflection.Assembly.GetExecutingAssembly());

I tried controls.DetailsActions ( because it's in a folder called 'controls' ) to no avail. I've tried various other permutations, and I've also established that all my other image lists ( that reside in the root folder ) are loading fine. I've also reverified that the existing code works perfectly in the VB.NET version. I have no idea what to do next...

The ResourceManager should - if the file "path" in the manifest is the same as the fully-qualified class name - use new ResourceManager(typeof(DetailsActions)).

Make sure the .resources file is in there. Open the assembly in ildasm.exe (installed by the Framework SDK, which is installed with VS.NET by default, into the SDK's Bin directory), double-click "MANIFEST", and search for "RDC.controls.DetailsActions.resources" below the assembly attributes.

I found this:

.mresource public RDC.controls.DetailsActions.resources
{
}

Then in your DetailsActions.cs (assuming similar class and filename) do this:

new ResourceManager(typeof(DetailsActions))

The ResourceManager uses the Type namespace and class name and appends ".resources" to get the resource. If you were to specify the resource yourself, you would have to do:

new ResourceManager("RDC.controls.DetailsActions.resources", Assembly.GetExecutingAssembly());

Though the example isn't right, you might - for sanity's sake - look in the ResX file to make sure a data name with "imageList1.Images" (or whatever the key is) exists in the file.

Any class defaults to using the project's root namespace (configured in the project) + any folders. This is for C#. VB.NET, on the other hand, builds the namespace up for each folder and is not cummulative. Make sure your class files don't repeat namespace parts for folder that already exist.

Resources, in both cases, are handled like classes in VB.NET: the "namespace" is built from the project root namespace + any folders down the line to the file to embed.

Did that - it's there. It's .ImageStream, I believe, either way, it's the same thing the code that blows up is looking for.

Sorry, it did that originally, and I've changed it back. I should have said when you mentioned it before.

I really appreciate your help with this.

Make sure your source file in VB.NET doesn't include the full namespace, like:

Namespace RDC
  Namespace controls
    Public Class DetailsActions
      ' ...
    End Class
  End Namespace
End Namespace

What will happen, if the project's root namespace is "RDC" already, and this in a folder calls "controls", is that you'll have a fully-qualified class as RDC.controls.RDC.controls.DetailsActions.

If you're using the other overload for ResourceManager to specify the name, specify exactly the name you saw in the assembly manifest when using ildasm.exe, including the extension.

In VB.NET, it doesn't include a namespace at all. Could this be the problem ?

I'm using the typeof one again now, because that's what it was originally, I was just looking for a way to specify the namespace, but it didn't help.

*grin* what's happening here is that we're being paid to work on some code that was in VB, and we refused unless we could convert it to C#. We did this, using a conversion tool, and the authors of the tool can't tell us why this is happening, although it has something to do with the subfolder, all the other image lists are not in subfolders, and work fine.

It shouldn't. Whatever namespace is specified in the source file is appended to the namespace built up by the root project namespace plus any folders. At least that's what I remember from my stint with VB.NET 1.0 years ago.

Use ildasm.exe to view the type metadata. I'm sure you're answer lies there.

Once you get everything figured out, this is best. This allows you to move the source file and ResX file around in VB.NET. That's one nice thing. In C# you'd have to mind your namespace in the source file.

OK, well all it tells me is what I know - the full 'path' is RDC.controls.imageList.ImageCollection. I know that the .controls bit is what's making the problem, but I do not know what to do about it. I'm going to read Pezold about it tonight and see if he says anything. His windows forms book is full of info on GDI+, but very thin on what controls he actually even uses, so it's a mixed bag.

The namespace is RDC.controls, but what are you referring to as a "path"? I can help you (I've dealt more with localization of managed application than most people I know), but I need to understand what you're looking at exactly.

The source file will have a namespace, but in VB.NET - unlike in C# - you don't specify the entire namespace (if any) in the source file. If you use ResourceManager and pass it a Type to the constructor, then the namespace of the embedded resource and the namespace of the class must be the same, as do the class names. The embedded resource simply adds .resources to get the resources file.

So, if the fully-qualified class name is RDC.controls.imageList.ImageCollection - which doesn't make any sense from what you've told me already - then the .resources file should be embedded as RDC.controls.imageList.ImageCollection.resources.

The VB.NET project treats source files and embedded resources the same. It builds up their namespaces using the project root namespace + any folders up to the file.

Yesterday you told me that the class was RDC.controls.DetailsActions. When you say "path", are you talking about the data name in the ResX file? The name in the ResX file should match the name that you get using ResourceManager.GetObject.

If you specify a "path" (fully-qualified manifest resource name) for ResourceManager than it must include the entire "path": RDC.controls.DetailsActions.resources.

If you can, why not post some sample source and the structure of your project. And define what you mean by "path" and to what that "path" refers.

Stop the presses !!!

Thanks for all your help - I tried loading the resourcemanager with this:

System.Resources.ResourceManager resources = new System.Resources.ResourceManager("RDC.controls.DetailsActions", System.Reflection.Assembly.GetExecutingAssembly());

and it works fine. I'm at a loss though, I'm sure this is what I tried yesterday....

Have you checked the 'DefaultNamespace' property of your project? The namespace in which a .resx file is placed is determined by studio to be:

[DefaultProjectNamespace].([Folder].[Folder].etc).ResourceFileName

If this production does not match exactly the declared namespace for your class, the ResourceManager won't be able to find the resources for the class. This has happenned to me on numerous occasions after moving around classes in a project that has a non-standard DefaultProjectNamespace (e.g. it's not just 'AssemblyName').

This is kinda low-fi, but have you looked for your resource by outputing Assembly.GetManifestResourceNames()?

Also, reflector provides a list of all the resources in the assembly.

What you need is a RichTextBox. Read about it on MSDN

thanx thats help

The System.Drawing.Point Class has really a lot of missing Features. It has no TypeConverter and no support for operators like + and -. This is really weak.
Is there any possibility to fix that issue? Sure... I could write an own Point class but that one won't be compatible with all the (drawing-)functions like DrawPoly and I don't want to write some ugly conversion code.

Yes indeed, and everything is explained on MSDN. All my fault Frown | :(

Actually I tried to convert a string into a point and also tried to sumarize two Points. Well, at least now I know how it works Smile | :)
