Using PInvoke in C# with function pointer and delegate -

-

i'm new in c#.

i have c file (and im using make dll file) :

extern "c" {     typedef int (__stdcall * t_fun)(int);      __declspec(dllexport) int __stdcall executec(int n, t_fun f)     {         return f(n);     }  }

then want use in c# code using pinvoke.

public delegate int f_delegate(int n);  [dllimport("executec.dll")]         public static extern int executec(int n, f_delegate func);  public static int funcs(int n){ return n; }  static void main(string[] args) {     int x = executec(13, funcs);     system.console.writeline(x.tostring()); }

and when start program ends immediatly. problem here?

the code in question fine. can verify pasting brand new projects , discovering works well.

the plausible explanations can see are:

  1. the program runs correctly , ends after starts because expected behaviour. after program prints single value , terminates.
  2. your code in fact different presented in question.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
