• .NET Development Object does not match target type when raising an event from c# to VB6

  I have a c# .net DLL that I use from a VB6 app. It exposes an event, and the VB6 app is sinking it. The VB6 app is receiving the event, as long as it is raised from the main thread of the .net DLL. I have an aync task being handled inside the DLL (delegate BeginInvoke). Any attempt to raise the event from within that thread casuses the reported error, even from within the AsyncCallback function, when the thread is ending. I noticed that the dele ...Show All

  How can I check if the file is already open through C++ programming. I tried to use LockFile() and _lockfile() functions but they both require number of bytes to be specified.
