Hi
Can anybody tell me how to get a function to call another function once it
has finished processing. That is, I have a function which I run, in its own
thread, which does some processing. As soon as it is done, I would like it
to call another member in the main form of the application.
Can anybody give me some ideas on how to do this? I seem to recall reading
something about a callback function (?) which may do the job? Is that right?
Some example code would be great!

I'm faced with a situation where I will need to calculate a column for
a resultset by calling a component written as a VB6 DLL, passing
parameters from the resultset to the component and setting (or
updating) a column with the result. I thought that perhaps the best
way out would be to create a UDF that passes the parameters to the VB
component using the sp_oa* OLE stored procs.
For a test, I created an ActiveX DLL in VB6 (TestDLL) with...

I have a multi-threaded C# console application that uses WMI

Hello again (and again, and again...)
I think I'm getting closer to solving my initial problem of calling
unmanaged code. I managed to call the functions with user-defined structs
w/o getting any run-time exceptions. The problem is that I'm receiving a
Failure return (it returns 1 = "Failure"). I have a feeling it may be that
the function's not reading the struct correctly.
This time I decided to display all the code (it's very short)....

My problem: I need to call (from C code) an arbitrary C library

use dlopen/whatever to convert the function name into a pointer to

As far as I can see, there are only two solutions:

On page 392 of "Javascript the definitive guide" a function is called
like this:-

Why, in this instance, is the return statement used in calling 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.

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,...
