Re: PostMessage() Error

Here is the original function using PostMessage:

     while(*pc) {
         PostMessage(hwnd, WM_CHAR, (unsigned char) *pc, 1L);
         pc++;
     }

}

Here is the modified function:

void
PostString(HWND hwnd, char *pc)
{
     if ( (SendMessage(hwnd,WM_SETTEXT,NULL,(LPARAM)pc)) == TRUE) {
            printf("Text put successfuly\n");
      }
}

I see "Text put successfully" is printed multiple times successfully,
it means this function works fine, does it mean that the original GUI
source needs to modified to get it work.

The problem is that no plotting is generated after sending the message
using SendMessage() of WM_SETTEXT.

Originally using PostMessage() or using SendMessage() of WM_CHAR, the
generated plot is messed up, meaning the data is received but got messed up.
