Is there a way to prevent multiple instances of a specific dll?

[rvr]

Hi,

I created a dll which is referenced from another project. But it seems as if this dll gets referenced twice when the program is run, because the variables change somewhere without appearant reason.

Any idea on how to solve this, or even if there is an idea on what else might cause this, would be appreciated.

Thank you,

Hi rvr,

This looks like a problem that the Debug tools were created for.

A couple of suggestions:
run the project in break mode and see where the dll is referenced the first time and where the dll is referenced the second time.

Add a watch and put the expression that occurs when the value changes. Do this for each variable that changes.

You might want to review the testing stage of your development process. It's very easy to omit some of the necessary stages of the testing process. The result, though, is that problems like this one can occur if a project is not thoroughly tested at each stage of the development process.

Good luck.
