Pinvoke - LockWindowUpdat e

I am using the LockWindowUpdat e API to lock my form while updating and
then Unlock when I am done. It was pretty simple to make the call to
lock the form with the form handle but how do I Unlock it?

I can't seem to get it.

Thanks.

Gene,

You would call LockWindowUpdat e and pass IntPtr.Zero as the parameter
(equivalent to null).

Hope this helps.

Is it possible to use mailslots in .NET using PInvoke? I have a VC++ 6.0 based app that creates and listens to a mailslot. I have a second VC++ 6.0 based app that opens the mailslot and writes to it successfully. So this stuff works. Additionally, I have a VB.NET app that opens the mailslot successfully using CreateFile() (with PInvoke). What looks like a proper handle is returned and there is no error.

Hello, I've been having a pickle of time trying to find any information about the following. The Win32 API has a function called 'LockWindowUpdate' which, if I'm not mistaken, prohibits all painting of the window including children controls until unlocked. The only thing that I can find that even seems close in .NET is SuspendLayout and ResumeLayout, but these don't really effect painting - just sizing, moving, docking, and anchoring. ...

Are there issues I need to be aware of with regards to threading a simple pinvoke...

Hello, I have used the API Function "LockWindowUpdate" in my VB 6 applications and was curious if this API function still exists in VB.Net. I have spent 4 hours surfing the 'net for an example but found nothing that seems to work. If "LockWindowUpdate" is still valid in VB.Net could some provide a sample where a form is locked? Cheers, Richard

After numerous problems, I'm having second thoughts about using C++/CLI to wrap a native DLL. On the other hand, PInvoke seems like it will take a huge amount of work, if it will work at all. The native DLL uses raw data buffers that are normally handed to it (via pointer) from another native function. If I'm piloting this with C#/PInvoke, how could those raw data buffers be created and immobilized? In C++/CLI, there is pin_ptr to...

Hey there, this will be somewhat a long post, but any response is appreciated! I have done many PInvoke in the past from C++ to C#, but I did PInvoke within C# not C++/CLI. Can someone explain more why C++/CLI would be better to PInvoke than doing the PInvoke in C#? Because, usually in C# as you already know we use DLLImport and extern

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,...
