  : I use Visual C++ 6.0.
  : I've got two problems.
  : First I want to start an Exe File when klicking a Button in my Application. What do I have to write into the BnClicked Funktion?
  :
  [blue]In the resource editor, just double-click the button. ClassWizzard will create a function for you.[/blue]
  
  : Second I want to delete a Text file, which I have accessed with:
  :
  : ifstream fin("info");
  : char str(80);
  : int i;
  : fin>>str>>i;
  : MessageBox(str+" "+i);
  : fin.close();
  :
  : So after reading the Data out of the File, I want to delete it. What is the easiest way to do this.
  :
  :
  : PS.: Please keep it simple since I'm a Newbie in C++ programming and the programm mustn't be absolut professional.
  :
  [code]
  remove("filename");
  [/code]

  also for the line
  char str(80);
  it should be restated to
  char str[80];
  or
  char *str = new char[80];
  seing that an arry is defined by [] brackets

  First: I think I made my self missunderstood. I actually have this function you described, but with this function I want to start another .Exe outside my Programm.
  [code]
  void Admin::OnInsertMember()
  {
  //Starting "Login.exe" here
  }
  [/code]
  And now I need some code to start this Login.exe.
  
  Second: Thanks, that's what I wanted.
  
  @TFKey: Thanks, typing error which I have already corrected in my code.

  What about ShellExecute? Or is that just VB (Cause I am a VB programmer... learning C++ MFC!)
