Using SendMessage API

[penahill]

I need to find a window and then fill in some text and the click on the OK/Save button. I am able to find the window by using EnumWindowsProc. I think I need to use the SendMessage function but in the declaration the wMsg is declared as a long but I need to pass a string.

I need to pass the string from a VB program to a non VB window and then click on the OK/Save button.

Any help would be greatly appreciated.

Thanks

The message is a Microsoft predefined message (and is a long, not text). Take a look here:

if you want to send text to another program (for instance, filling text into a textbox), you are going to send a WM_SETTEXT message using SendMessage. The parameter is the text (long pointer to the null-terminated text which VB will magically do for you for free) that you want the textbox to be set to:
