Re: So the question remains, How do you get an IntPtr to an executable containing a resource? - C# Discussion Boards

Not solved. We need to get a handle to the assembly.

So the question remains, How do you get an IntPtr to an executable containing a resource?

16-May-07 8:17

No, my call to Assembly.GetAssembly( t ) gets the assembly. That isn't the problem. The problem is getting an IntPtr handle to the assembly.

Any ideas on that? Since I can identify the proper assembly with Assembly.GetAssembly( t ), and since my call to IntPtr h = Process.GetCurrentProcess( ).Handle does not (?) appear to be returning a valid IntPtr to the executable containing the resource (my assembly returned by GetAssembly( t)), I am hoping there is somehow a way to get the IntPtr from my GetAssembly( t ) result.

That seems straightforward, but perhaps another way is intended to be the process.

In any case, all reasonable suggestions are appreciated. I'm traveling in just a bit, but will return to the forum in a few days.

In other words, you can't do this, and there doesn't seem to be a way to cast or otherwise derive the IntPtr value so that you could do the equivalent of this:

Glyph1.GMap = Bitmap.FromResource( ( IntPtr )Assembly.GetAssembly( t ), s );

So the question remains, How do you get an IntPtr to an executable containing a resource?

I don't know what to say at this point. As far as I am aware I gave you a solution that works, in my experience, and you have not tried it.

Re: So the question remains, How do you get an IntPtr to an executable containing a resource?

16-May-07 9:08

No, I tried it:

Glyph1.GMap = Bitmap.FromResource( ( IntPtr )Assembly.GetExecutingAssembly( ), s );

FromResource requires an IntPtr. As I indicated in my question, I need an IntPtr to the executable containing the resource. According to documentation, what you need to do to get *that* assembly is:

Type t = this.GetType( );
Assembly a = Assembly.GetAssembly( t );

This gets the assembly. The problem is, getting an IntPtr hinstance pointing to the assembly from the assembly.

Are you saying that you can get an IntPtr from your calls, because I don't see that in your answer?

This is just one permutation of what I tried with GetExecutingAssembly( ). If what you're intimating is that I need to try Assembly.GetManifestResourceStream() to retrieve the bitmaps so they can be assigned to my properties, I'll have to explore that later (?). I'm late to hit the road, but thanks so much for trying to set me straight on this. I'll get around to it as soon as I can.

intimating? Since this is a forum based conversation I don't know how more clearly to state it than putting it directly in the post which I did. Roll eyes | :rolleyes:

Re: Getting an IntPtr handle to an instance of the executable file that contains a resource.

16-May-07 9:17

In other words, we can get so far as acquiring a "ModuleHandle" from GetExecutingAssembly -- but I can do this with GetAssembly as well:

Assembly.GetExecutingAssembly( ).GetModule( "APC" ).ModuleHandle;

ModuleHandle however is a struct with no field or conversion method which converts to an IntPtr to the instance of the assembly. That's the missing piece: How to get an IntPtr from the assembly, or something else, which identifies the executable containing the resource.

GetExecutingAssembly just looks like another course to the same dead end to me, unless we can get that IntPtr somehow.

But thanks for the try!

i guess you are confusing managed and unmanaged resources.

try using reflector to see whether it is a .net managed resource.

Re: Getting an IntPtr handle to an instance of the executable file that contains a resource.

16-May-07 8:46

No, my resource is managed. I've added many bitmaps to my class library DLL by the visual process, Project.Add... Existing file...

Determining whether it is a managed resource is not the problem. The DLL is loaded by a test application, using the classes as they would typically be deployed. The problem is for the class, when it is in the test application (exe), to assign the bitmap resources to property, preferably with the Bitmap.FromResource( IntPtr hinstance, String bitmapName ) method.

Re: Getting an IntPtr handle to an instance of the executable file that contains a resource.

16-May-07 9:21

But Bitmap.FromResource is for unmanaged: "...Creates a Bitmap from the specified Windows resource..." (http://msdn2.microsoft.com/en-us/library/system.drawing.bitmap.fromresource.aspx[^])

Whoa. Jumps out and grabs you when it's in Bold!

Smile | :)

I guess I need to learn to *read*! I suppose I was so intent on loading and embedded resource I just assumed this was the method (what other method is there?). So this *does* require calling into LoadLibrary to get the hinstance.

I'm going to have to look around to see what method to use to retrieve my managed resources, because that's the way I want to do it. I hope that isn't some odd implementation of "FromFile", even as the resources are managed -- maybe so?

In fact it's rather easy. Just use the Windows Forms designer and assign an image (e.g. to a PictureBox).

Then take a look at the MyForm.Designer.cs file and see the designer-generated code that loads from the resource.

Adapt it and do it in a similar way.

I want to use Visual Studio 2005 Team Testing System in my application. I got the link from :
http://www.windowsdevcenter.com/pub/a/windows/2006/01/03/unit-testing-in-visual-studio-2005-team-system.html?page=1[^]

The version info about VS2005 I am using is:
Microsoft Visual Studio 2005
Version 8.0.50727.42
Microsoft .NET Framework
Version 2.0.50727
Installed Edition: Professional

1) Is Team Testing already integrated with the version I am using?
2) If not how can I upgrade same.

Any help/links will be appreciated.

Thanks and Regards,

Hi,

I need to create a mouse dragbox type of event, much like when you click and drag the mouse on the desktop, it creates the dotted line "box".

Does anyone know of any articles on how to do this?, i've thought of listening to the mouse click/move event and then drawing a rectangle from the posistions, but it would be much easier if there was a inbuilt event.

Regards,
Gareth.

Sure. You can descend a class from Control, and add a textbox, button, and listview to it.

Evidently, Uwe believes your question pertains to adding the textbox and button to a subcomponent. My interpretation of your question is that you want to add a textbox and button to an exterior region. To do so, you would probably want to derive a root or base layer from Control or UserControl, and add your ListView, TextBox and Button to that.
