Programming a window with two buttons

[zubr]

Hi,

 

I am looking for a function in a script that opens a window with some information (that I pass as a string) and has to buttons to select "OK" and "Cancel". If "Cancle" is chosen, I would like to exit the script. 

 

Thank you.

 

Best,

Chris

MessageBox function.

MessageBox function.

OK, that's what I was looking for. If "Cancle" is clicked, I would like to immediately exit the script. Is there a function for that?

You only have to check the returned code and use the return statement from OnStart() function, something like :

   void OnStart()
     {
      ...
      int result= MessageBox("Message...",...);
      if(result == IDCANCEL) return;
      ...
     }

This would be one feasable solution if I would invoke the function with MessageBox within OnStart(). However, I invoke MessageBox deeply embedded in my code, like OnStart()=>FunctionA()=>FunctionB()=>MessageBox(). So I had to pass the return code from MessageBox to FunctionA an from FunctionA to OnStart().

 What I am looking for is a function that immediately exits the script where I don't need to "jump back" to OnStart(). Is there such a function?

I am programming a script to set an order. So this is not an EA. While placing the order I want to exit the script when some comditions are not met.
