I have a 3rd party library (.lib) file with two header files which I have
wrapped in a c++ .net dll. I am trying to use that dll in an asp.net
project but I get the error "Object reference not set to an instance of an
object."
I added the dll to my project as a .net reference and I can see all exposed
functions in the object browser. The function call(s) that causes the error
is
sweep_output_t* sweep_output = new sweep_output_t;

because I havent' been able to locate the origin of the problem for a
couple of days now..
PROBLEM: the message digest obtained differs each time I execute the
code, but works perfectly when applying the "control", that...

Since 10 days (the first time was the 10th of november) I have some weird
exception happening in an application here:
All (except 1 of the total of 5) users had this error now 1 of 2 times
during the last 10 days. It happens mostly during startup or closing of the
application, but sometimes just in the middle of nowhere. It doesn't point
to anyting special. I don't get a clue...
It's a Windows Forms VB.NET 2005 application. I roll...

Hi !
I get the error below sometimes when retrieving a big amount of data using Datadapter.Fill(dataset,"table"). But when I send the command Fill again, there is no error. Is it a fault of IBM.Data.DB2.iSeries; Version: v1.0.3705 (is there an newer one for OS/400 Version ist V5R3 ?) or is it a hardware faoult (memory of as400 or pc) ?

I'm trying to use a DLL that was built with Visual C++.NET 7.1 on a new program that I'm developing in VS2005 C# program.
Every time I call a function of the 7.1 DLL I receive an anoying AccessViolationException
I followed the code, and found that the problem is originated on a simple malloc call:
LPBYTE imData = (unsigned char *)malloc(100);
Does anybody has an idea of why this is happening?

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,...
