Unmanaged C++ to call C# dll with automatic registration when buildning or without COM?

Question

I have a function in C++ that needs to call a C# dll. The C++ function simply sends values to the C# dll functions. The C# dll uses these values to produce some files and then finishes.

My problem is that when using COM I need to register the DLL everytime when using a different computer. So, is there any way to register the dll file and produce a .tlb file on build?

copy $(TargetPath) $(TargetDir) C:\WINDOWS\Microsoft.NET\Framework\v2.0.50727\RegAsm.exe $(TargetPath) /codebase CReportGenerationDLL.dll /tlb:CReportGenerationDLL.tlb

This is what i have tried, but it wont work.. I get exited with code 9009

If your meaning is to register your COM object automatically each time when building your application on another compputer, then the answer is (assuming you are using VS2010 for building) : Go to Project/Properties/Build events and add to the "Post-build event command line" the following line:

regasm <path to your COM .dll>

If your meaning is to register your COM object automatically each time when running your application on another compputer, then you can create a batch file which contains:

regasm <path to your COM .dll>
<path to your application>app.exe"

Or just call regasm.exe from your application using ShellExecute function.

You may want to add /s switch to make the registration silent.

Error 9009 says that your path to regasm is wrong, see here

copy $(TargetPath) $(TargetDir) is out of place, why do you need this, what are you trying to achieve?
