I'm writing a wrapper for a dll. The dll has a method whose signature resembles the following: unsigned long aMethod(void *anyParameter, void (*anotherMethod)(const char *, void *)) I've searching at google for a tutorial to give me insight on how to write the signature on C# so the framework can do the marshalling process. How can it be written? Do you know about any tutorial, book or documentation on this subject? [UnmanagedFunctionPointer(CallingConvention.Cdecl)] delegate void AnotherMethodDelegate(string s, IntPtr anyParameter); [DllImport("dllname", CallingConvention = CallingConvention

I'm trying to access a .Net library (The Image Resizer) from COM (jscript). I've tried both IDispatch and class interface generation, as well as [ClassInterface( ClassInterfaceType.AutoDual)] on the class in question. There is a method with 3 overloads: Bitmap Build(object, ResizeSettings settings) void Build(object source, object dest, string settings) void Build(object source, object dest, ResizeSettings settings) Calling Build("file",s); //works The following both generate "Wrong number of arguments or invalid property assignment" (JScript runtime error) Build("file","file", s) Build("file"

I'm trying to inject some Scala code into my existing Java app. (So, being said, I want some more fun). I create a singleton stuff in Scala ScalaPower.scala package org.fun class ScalaPower object ScalaPower{ def showMyPower(time:Int) = { (0 to time-1).mkString(", ") } } Now, inside OldJava.java class OldJava { public void demo(){ System.out.println(?) } } What should I fill in ? so that Java will call the showMyPower method? I tried both org.fun.ScalaPower.showMyPower(10) and org.fun.ScalaPower.getInstance().showMyPower(10) but none work. (Decompile the class file using Jad show me nothing

I have some c# code which opens a Powerpoint slide, refreshes the graphs, and then quits. This works fine, unless the user already has a Powerpoint slide open, in which case it will close down their existing session (losing any changes they may have made!) once the exe has run. So, the issue is if you have PPT’s open in the background, run my EXE which runs the below code (opening up a template, refreshing some graphs, saving and closing), upon application exit it disposes of the variable ppApp which seems to close down every running PPT. This is even the case if I omit ppApp.Quit();
