Hi Norman,
One Visual Studio 2005 solution contains a C# project and C++ ATL DLL project. The DLL compiles fine, gets registered automatically, gets referenced correctly when the C# program compiles, and gets called correctly during execution. So far, so good.
...
When not executing, Visual Studio displays a brown dot saying that the breakpoint is valid. When executing, Visual Studio displays a mostly transparent dot with an exclamation mark saying that the breakpoint is not valid. I can right-click the dot and set an option for the "place" of the breakpoint, but it doesn't matter. The breakpoint never gets hit.
Two things:
1) are you using debug builds?
Yes of course.
2) did you enable mixed debugging for managed und unmanaged code? Project->Properties->Debug "Enable unmanaged code debugging"
That was almost enough information to find it. Thank you. I know not to shoot the messenger for this incredibly bad design, and I thank you for informing me.
The solution has two projects in it. Visual Studio's options, Tools - Options - Debug, don't do anything to prevent debugging (I suppose they could be set to prevent debugging but I didn't do so). In the DLL's properties, the debug options don't do anything to prevent debugging. You described an option which is available in the C# project's properties. In order to debug project #1, it's necessary to right-click project #2 and set project #2's properties to enable debugging of project #1. What an easily discoverable (not) way to stop breakpoints from breaking in project #1.
Coming next: To shut down your computer, don't click Start on your computer, but click Start on your neighbour's computer.
