• Indinfer AxtiveX control in mixed assembly

  I have a COM dll - written in C++ - that implements a large number of complex objects, some of which are controls. I want to be able to offer this as a "native" .Net assembly. I have therefore built a mixed assembly containing new managed wrappers around the old unmanaged objects. This has gone well, and I'm now able to use the assembly from a managed app exactly as I would any other .Net assembly. The ability to debug from one to the other is truly astounding. I noticed that my controls were not repainting as they should, and traced this to the fact that the container/control OLE interfaces were not geting wired up correctly. The faint sound of a large can of worms opening becomes slightly louder... Currently, my manage ...Show All

Being natrualy lazy I was hoping there was some little known property or method I could use, but failing that I shall give your approach a bash. Cheers, Gareth absolutely. One way would be to iterate through each row and each column and then set the cell value or for each row, get the specific column you are after in the cell property, check its v ...Show All
