We're authoring a VS 2005 app that includes several EXE's and DLL's and also
uses a COM component (a customer requirement). The COM component provides a
graphic image to be used by the .NET app; the graphic is supplied as a
"StdPicture " (AKA, IPictureDisp).
How can I convert this to a .NET Image? A search of the object browser
shows:
protected static System.Drawing. Image GetPictureFromI PictureDisp(obj ect
picture)
Member of System.Windows. Forms.AxHost
and in VB.NET
Microsoft.Visua lBasic.Compatib ility.VB6.IPict ureDispToImage
Is there any other, more workable way to accomplish this conversion?
TIA ...

What do you mean by "more workable"? What's wrong with the method you
listed?

Hi Mattias,
Thanks for responding.
Of these two methods, using the AxHost method would appear to be a kludge -
or at least inappropriate - for a library (DLL), as I think it would require
a control on a windows form.
And using the VB6 compatibility layer of VB.NET just seems kind-of ...
silly? ... for a C# library.
I'm sure I must be missing something ... but I just don't see what that is!

You don't need a control on a form, you just need a class that derives from
AxHost so that you can call the appropriate protected static methods. This
will create a dependency on System.Windows. Forms.dll.
The alternative is to create a managed definition for IPictureDisp so that
you can retrieve the GDI handle of the picture object. You can then use this
handle to create an appropriate GDI+ image, e.g. Image.FromHbitm ap,
Icon.FromHandle , etc.

DUH! - you're right Kevin - I missed the "static" attribute.
Thanks

I am trying to save the contents of a form as a bitmap and am unsure how to do this. I can use the savepicture command to save the form as a bitmap but the contents is not intact as you would expect. There is 1 picture box on the form which I wish to save with the form so really a full screen shot of the form.
Taking a screen shot and saving it won't do it either as the form is only a section of the screen say 640 X 480 and is centred on the...

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
g++-12 -std=c++20 -Wnarrowing bit_field.cpp

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,...
