Origin Version (Select Help-->About Origin): 7.5 Pro SR6
Operating System: WinXP all updates
MS Visual C++ 6

I want to program a tool window similar to the linear fitting tool, but not tabbet, only a simple dialog. My OC program without the dialog runs well. I made a dialog resource following the "Creating A Microsoft Visual C++ Resource-only DLL" chapter in the programming help, and I can launch it modal. But I want to have it non-modal like the linear fitting tool.
In "Launching Dialog Builder Resources with Origin C" I'm adviced
quote:
Locate a function in the source file (*.c or *.cpp) that contains code constructing an Origin C object of type Dialog and calling either the Dialog.Create or Dialog.DoModal method. The Dialog.Create method launches a modeless dialog and the Dialog.DoModal method launches a modal dialog.

I found only the Dialog.DoModal method. I changed the files made by the Dialog Wizard as follows:
MyDialog.cpp
bool DoMyDialog() 
{
	MyDialog myDlg;
	myDlg.Create( GetWindow() );
	return true;
}

MyDialog.h
class MyDialog : public Dialog
{
public:
	MyDialog() : Dialog(IDD_MYDIALOG, "MyDialog")
	{
	}

	BOOL Create(HWND hParent = NULL)
	{
		InitMsgMap();// will be called from internal later
		BOOL BRet = Dialog::Create(hParent);
		return BRet;
	}


When I launch DoMyDialog, an "unhandled exception in origin75.exe (OK70.DLL)" is announced and CodeBuilder and Origin crash.
What do I wrong? I cant help myself anymore.

Edit: Changed bool ==> BOOL, but the exception does still occur. Don't anybody know an example of a modeless dialog made with OC?

Hi,Mathias

Following is the method to made a modeless dialog,in Origin Version 7.5 ProSR6,you should change the function
DoMyDialog() as belowing: 


static MyDialog MyDlg;
BOOL DoMyDialog(BOOL bClose=FALSE)
{
	if(MyDlg.GetWindow())
	{
		if(!bClose)
		{
			out_str("Dialog already open");
			return FALSE; //already open
		}
		//we will need to close it
		return TRUE;
	}
	
	return MyDlg.Create();
}



In Origin Version 8.0,the method as you mention will works well.

Thanks
Vinden
