Hi
I am trying to access the listview items from a SysListView32 control
in C#. I am using LVM.FINDITEM and LVFINDINFO through SendMessage to
try to get the text from each column in the item (it is a multi-column
list view).
I am using the PARTIAL flag to try to find an item starting with a

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.
Regards,

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.

For most users, this new feature is actually very convenient. If you want to control the update process,...
