Hi All
I need to get the audio messages using WndProc to determine the right time to close a waveout device and release the buffers. I tried to override WndProc but I don´t receive any message related with multimedia like MM_WOM_DONE, but I get all the messages to mouse click or button press. Need I use some special inheritance? I´m using NativeWindow ..
Anyone has some suggestion?
Thanks in advance
Mauricio

Greetings!
I have a VB.Net 2003 project that was originally written in VB6, converted
to VB.Net 2002, and then converted to VB.Net 2003. I am trying to handle a
form's Resize event. I put a breakpoint in it and saw that that event got
fired four times before the form's Load event got fired! I then saw that I
have the following routine in the form's code:
Private Const WM_SHOWWINDOW = &H18
Private m_loaded As Boolean

OK, I have a form with a menu and a tool bar. In the Menu I have a File
menu that contains a "Exit" item. When I click this Exit item. I have an
event wired to:

I'm working on an owner-drawn combo box which has extended
functionality. I have to do something to the dropdown list when it
drops down, then undo it when it is closed up again. But I can't see
an event which seems to be a "CloseUp" event - is there such an event?
Surely there must be!

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,...
