Open MDI child in existing application

Hi,

I am trying to get a file with extension .xxx to open
as an MDI child inside an application (ABC.exe), which I
created. I made a file association so that it will open
with ABC.exe, but instead of opening it as an MDI child of
an existing ABC.exe, it opens it in a whole new ABC.exe.

An example of this would be similiar to when you click
on a header file, Visual Studio(VS) will open that file
inside an already existing VS instead of opening a whole
new VS. I want my application to have that same effect.

There was a similiar post by Jason Gleason which
mentioned using Running Object Table (ROT), but it seems
like ROT uses COM, but my app doesn't use COM. I want my
app to call a function so that it would open the file in a
certain way. Is there any way to do this? An example on
how this can be done would be really helpful and any help
would be appreciated. Thanks in advance.

John

But, if it's not open, I don't want to open it . . . using window.open will open it if it doesn't exist, even if the url in that open is null (the window is then empty -- but it's open).

The user may click in any child window or the main window to open a summary window, which has a name all windows know. I want to get that...

Ok..this a rather odd question/problem. I haven't really found a straight forward answer to how to handle this scenario, so I hope someone here can help. Here it is: I have an application that allows users to log in. Each user can have multiple roles within the application. Each role allows the user to access different sections of the app and allows/denies them certain functionality.

I have a MDI form, sometimes child forms and sometimes forms that are neither If I close the app the child forms closing and closed event happens followed by the Mdi form receiving the events.. But the regular forms that are also open do not receive that event. This is true whether there are child forms open or not.

Hello folks, I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
