Hi,
As any one worked in VB.NET and made use of Sendmessage API?
The Issue I am running into is how to pass pointers of Data Structures (UDT)
to the SendMessage.
I starting looking at "IntPrt" as a data type but it appears to fall short
of using pointer types.
Any help or insight would be greatly appreciated.
Thank You 3 10164

Well, you generally declare the parameter as ByRef ... As MyUDT. If you
have a specific example of what your trying to accomplish, I could be
more specific.

Please give us more details on which message you use. Maybe you whould pass
the structure by reference.

Hi JSK, For each data type you want to use in the lParam of SendMessage,
you'd declare an overload for it:
SendMessage(Int Ptr, Integer, Integer, Integer)
SendMessage(Int Ptr, Integer, Integer, String)
SendMessage(Int Ptr, Integer, Integer, IntPtr)
SendMessage(Int Ptr, Integer, Integer, MyStructure)
SendMessage(Int Ptr, Integer, Integer, Integer)
Structures need to be passed ByRef
Please provide an example of your code.

Hi all,
I am having trouble converting the code below (found on
http://vbnet.mvps.org/index.html?code/core/sendmessage.htm) into a
format that will work using vb .NET.
Can anyone have a look at it and let me know what I need to change. I
have tried changing the "hwnd" type into intptr's but there seem to be
other problems too, like it won't allow "lParam As Any" to be
declared.

Hi,
My application has a lot of threads which at some point call SendMessage api
passing it the handle of the gui window. The calls r a lot. My question is
that should I call the SendMessage api by protecting it in a critical
section, or the SendMessage api itself handles this kind of situation where
a lot of threads in the same process r calling it.

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.

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,...
