conversion problems

[venerable bede]

I have an API I have to interact with which was originally written in Delphi.
It contains a method which needs an integer passed to it which represents the handle to the current window.

The problem is that in .net as far as I can see the handle to the current window is of IntPtr type and cannot be converted to an int type.

e.g.

 
System.IntPtr myHandle = this.Handle;
workflowAPI.myMethod(Convert.ToInt32(myHandle));

Error "Unable to cast object of type System.IntPtr" to type "System.IConvertible"

Any Ideas Chaps and Chapesses ?

Why, is it too hot for you? :rofl:

Try

 [DllImport("user32.dll")] 
	    public static extern int FindWindow(string strclassName, string strWindowName);

Then use FindWindow to get the int value, passing it to myMethod. Just remember not to fly off it during the process. :rofl: :rofl: :rofl: :rofl:

Try the IntPtr.ToInt32 method.

Or declare the parameter as IntPtr in the first place; assuming it's a standard DLL.

Thanks all

I ended up parsing it to string and it magically worked.

I like overcomplicating everything.
