Sure, here is one message being sent:
void __fastcall TfrmMain::btnStartClick(TObject *Sender)
{
SendMessage(WinHandle, WM_STARTSCRIPT, 0, 0);
}
Here's how I get the handle:
void __fastcall TfrmMain::btnFindClick(TObject *Sender)
{
WinHandle = FindWindow(0, lbeCaption->Text.c_str());
if(!IsWindow(WinHandle))
Application->MessageBox("Window not found","Error", MB_OK |
MB_ICONERROR);
}
Here's the definition of the message:
#define WM_STARTSCRIPT (WM_USER + 1000)
