Thread: VC++ simple prog HELP

TheForgers tutorial is a pretty good one...

...or you can post the code you've got and we'll help you get that working.

Remember, if you post your code, to post any resource files and headers you have made, so we can compile the program and run it in a decent debugger.

that was very deep and meaningful kuphryn. but lets help out anyway.

Okay, its sounds like you know how to create the edit boxes and buttons. what you need to do is capture the message that is sent when the button is clicked, and place your code there.
That can be done by checking the LOWORD of the wParam when the WM_COMMAND message occurs, to see if it matches the ID of your button. eg:

Code:

switch (msg)
{
case WM_COMMAND:
  switch (LOWORD(wParam))
  {
  case ID_BUTTON: //Whatever ID you gave it
     //Code here
    return 0;

The code will have to ensure that there is text in both controls, then convert it to numbers, and add it together. Then convert the sum back to a string and display it. ie:

Code:

char *str1=new char[256]; //Allocate strings to retrieve the input
char *str2=new char[256]; //ditto
int num1,num2;

GetWindowText(hInput1,str1,255);
GetWindowText(hInput2,str2,255);
//The above lines retrieve the text of the edit controls hInput1 and hInput2

num1=atol(str1); //converts string to long int, needs stdlib.h
num2=atol(str2);

ltoa(num1+num2,str1,10); //convert long int to string. 10 is the radix

SetWindowText(hDisplay,str1); //hDisplay is a control with a caption, ie an edit control

and thats it. ill post a full proggy in a tic.

the attached file is the source file for the proggy. what you should do is create a new win32 application, just an empty project, and add the file to it. it should compile fine. it worked for me.
