The below problem occurs randomly too, but I've managed to isolate a
sequence of events when it always happens:
I have two forms (say Form1 and Form2). Form 1 contains a TreeView control.
A button from Form1 opens Form2 and a button in Form2 sends the user back to
Form1.
When the user goes back to Form1 from Form2, the TreeView control rebuilds
the nodes incredibly slowly. You can see the progress, as the scroll bar
slowly starts...

Hi,
I'm a C++-Programmer and want to subclass the Edit used to write a
SQL-Query in Access. The edit is of the special Access class OKttbx.
Everything works, I injected a DLL into the Access-Process and the
subclassing works but I can't get the Windowtext of the control...I
tried the WM_GETTEXT message but it seems that Microsoft uses another
way to get the text the user typed in.
Has somebody an idea how I can get this to work?

What is the best soltions for creating a graphical object in c# for use in a
C++ app?
- I heard some say you can't create an ActiveX control in dotnet and I have
heard others say you can using some non-standard sutff that may not be
supported later on in dotnet. Is it or is it not possible?
- Is it pratical to have the C++ app ( non-managed c++ btw ) send a hwnd to
c# and have the c# app overlay itself on the hwnd?
If so, does anyone...

With this little DLL you can embed either Mozilla ActiveX Browser
Control or MSIE by just calling it's EmbedBrowser(HWND hwnd, int
i) function. 0 = Mozilla Activex Browser Control and 1 = MSIE.
Other available methods include:
>> UnEmbedBrowser()
>> ResizeBrowser(HWND hwnd)
Where hwnd is an handle to a control where the browser
control is

Hello,
I've written a Windows Forms application in .NET 2.0 and am exposing
it to COM using the checkbox in Project Properties and by adding some
register functions and adding it to the GAC. I'm using the ActiveX
Test Container (tstcon32.exe) and I'm able to add the control to the
container. All this works, well almost... I'm using some Invoke calls
from worker threads that update the GUI. In native .NET this means
that stuff is done on...

A VB6 ActiveX.exe raises an event which is seen by the VB6 App.
Same setup in VB2005. The event to be raised is in form frmSweep. As in VB6,
frmSweep is hidden when the events take place.
I know by actions on the screen and sounds in the speakers that VB2005 is
using the ActiveX.exe correctly.
However the events are never raised !!!

Let's talk about the concept of autonomous AI software engineers and no-code agents. These AIs are designed to manage the entire lifecycle of a software development project—planning, coding, testing, and deployment—without human intervention. Imagine an AI that can take a project description, break it down, write the code, debug it, and then launch it, all on its own....
