Its quite common to find applications with multiple windows or those that spawn other applications or other instances of itself.

For example IE can be launched via some 1. jscript code, or 2. by the user selecting IE to be launched from a toolbar, start menu etc, or 3. launched by some other application.

If launched using 1 or 3 how do I find out which application or which browser instance is the launcher?

Yes!

use the resource editor, when creating a dialog template, just remove the Ok button; or derive a class from CDialog and add it (Close button ) or remove the Ok button manually in the OnInitDialog method.

Max.

Or, if you are using SDI/MDI framework, add this line in

CMainFrame::PreCreateWindow (CREATESTRUCT &cs)
{
    ...
    cs.style = WS_SYSMENU; // have the small X button in the title bar
    return TRUE;
}

Owner drawn CButton position detection

I have several owner drawn CButtons created on a View. these buttosn are used to scale several plots on the same view. Because the buttons do the same thing (just to different plots, depending on which button is clicked) I want to use the same code to perform the actions. Ie. I do not want 6 different button performing the same actions.

What I want to do is when a button is clicked, detect which plot the user wishes to scale depending on the location of the particular scaling button they clicked. I am having a problem getting the location of the button within the view when clicked. Can anyone offer some assistance here???

Thanks

You can handle WM_COMMAND message in PreTranslateMessage of your view. wParam contains control ID, lParam contains handle to the control sending the message. Having control handle you can get it's rectangle.

Maybe ::GetMessagePos() can help you to get the position of the mouse click in the click-handler.

Or you could use differnt instances of the same CButton-derived class, having a constructor taking and storing the associated plot number in a member variable.
The click-handler would then work on this plot number.
This probably is the better way to do it.

GetMessagePos works like a charm.

It gives position in terms of the entire screen instead of the view, which I would like, but it will do the trick.

A big Thanks!

I had a similar problem when writing a context menu for CTreeCtrl.
You simply do CYourView::ScreenToClient(), and voilá - the client-specific coordinates!

I am trying to print the contexts of a CDialog that contains several ActiveX controls. I am looking for a function that I can send a pointer to the CDialog and it will prompt the user for the Printer to use. It would be helpful if the function would take into account Portrait of Lansscape. Any help would be appreciated.

Hi,
This will sound very basic and silly!!!
but can someone help me out with finding out how to go about
doing a substr() in C++;

Thanks,

doing a substr() in C++;

You use CString.Mid() (this requires MFC), or
you use std::string.substr() (this is standardized and portable), or
us use strstr(), the plain old C-Library function.

Its up to you.
