Adding MFC dll to C# application

[Idit]

Hi,

In case I want to use a MFC dll to my C# application.
Can I just add it as a refernce to the project and use it, or do I need to add something else.
I saw some examples with Assembly.LoadFile|("something.dll") - when it is used?


Thanks

Adding the DLL to the References should be enough.
Another way to do it, (albeit the hard way), is to use DllImport. For example, if you wanted to use the IsWindowVisible() call from user32.dll, the resulting code would look like:

  [DllImport("user32.dll", CharSet = CharSet.Auto)]
  public extern static int IsWindowVisible(IntPtr hWnd);
 
  // And later in the code you would call it normally
 
  IsWindowVisible(hWnd);

I thought it should be ok,but when I try to load the dll on another computer (not with VS2005) it fails to load (FileNotFoundException).
The dll is in the same dir with the exe. and the .net 2.0 framework is also installed.
Do you have any idea what could be the problem?

I don't have any idea...perhaps you should us what compiler it is?
