Hi
I am using 3rd party OCX control in my Application. Since the response time is too poor for that control, my application looks sluggish. So i tried to create the control in seperate thread and post the request to that thread. That works fine. But have some problem with that...
Code before threading model is implemented :
XControl = new TXControl( NULL ) ; //..Creating the 3rd party control
XControl->BackgroundColor = mBackground ; //..Changing the color
XControl->ForegroundColor = mForeground ;
...
XControl->ProcessMessage () ;
Code after threading modal :
I have moved all the processing operations to seperate thread and customization options in primay thread...
TServiceThread *lServiceThread = new TServiceThread ( false) ; //..Creating a thread and creating the 3rd party control
XControl = lServiceThread->GetControl () ; //..Get the pointer for the created control
XControl->BackgroundColor = mBackground ; //..Customizing the color in primary thread
XControl->ForegroundColor = mForeground ;
PostMessage ( lServiceThread->ID, PROCESS, 0, 0 ) ;
class TServiceThread : public TThread {
Execute () {
XControl = new TXControl (NULL) ;
while( (!Terminated) && (GetMessage(&msg, NULL, 0, 0) > 0))
{
switch(msg.message) {
case PROCESS : {
XControl->ProcessMessage () ;
}
}
TranslateMessage(&msg);
DispatchMessage(&msg);
}
TXControl *GetControl () {
return XControl ;
}
} ;
My problem is how can i ensure that XControl has been created before executing the below mentioned line :
XControl = lServiceThread->GetControl () ; //..Get the pointer for the created control
XControl->BackgroundColor = mBackground ; //..Customizing the color in primary thread
XControl->ForegroundColor = mForeground ;
Thanks in advance
