.NET Forum / .NET Framework / Interop / October 2004"regasm xxx.dll" vs "regasm xxx.dll /regfile"
Is this a regasm bug or does anyone have an explanation to this behaviour? I have a com dll that defines additional "Implemented Categories". When I register with regasm they are defined in the registry as expected. When I try to create a registry file with the corresponding settings by using regasm /regfile the created file is missing the additional "Implemented Categories". Below I have pasted the "regasm /regfile" created registry file and the corresponding regedit export done after a regasm registration (I have removed all lines except the "Implemented Categories"): - regasm /regfile result (is missing the extra "implemented categories"): [HKEY_CLASSES_ROOT\CLSID\{40928702-791B-40C5-B8B4-CDF84C3C8650}\Implemented Categories\{62C8FE65-4EBB-45E7-B440-6E39B2CDBF29}] -regedit export done after a registration with regasm (contains the extra "Implemented Categories"): [HKEY_CLASSES_ROOT\CLSID\{40928702-791B-40C5-B8B4-CDF84C3C8650}\Implemented Categories\{62C8FE65-4EBB-45e7-B440-6E39B2CDBF29}] [HKEY_CLASSES_ROOT\CLSID\{40928702-791B-40C5-B8B4-CDF84C3C8650}\Implemented Categories\{7DD95801-9882-11CF-9FA9-00AA006C42C4}] [HKEY_CLASSES_ROOT\CLSID\{40928702-791B-40C5-B8B4-CDF84C3C8650}\Implemented Categories\{7DD95802-9882-11CF-9FA9-00AA006C42C4}] How did you define the categories? With code in a [ComRegisterFunctionAttribute] class?

It generates hard-coded paths and omits RegisterClass calls. Don't use it for real, just debugging. bye Rob My problem is that I cant find any support in the MSI SDK for creating the necessary information in the MSM registry table. My idea of a workaroud then was to use regasm /Regfile to create the necessary data and then I would use it to populate the MSM registry table. Do you know a better way?

Even my old InstallShield Express 4.x supports the option "Register for COM interop", so I did't had to deal with this problem. You may try to execute regasm from a Custom Action. bye Rob > Thanks, > GT [quoted text clipped - 7 lines] >>bye >>Rob Are you sure that Installshield 4 express really covers the extra implemented categories that you may add to your code? Since the installer SDK does not cover this it seems to mee that they will have the same problem. We are using a custom action right now but I really thougt that msi would offer a more elegant way to do this. It's mainstream (in the mixed com and .net products) and for such things you should not need to develop and call custom actions?! Thanks, GT > Hi, > [quoted text clipped - 23 lines] > >>bye > >>Rob It might work if you go to the properties of the assembly (select it, then F4) and then set the Register property to vsdrsaCOM (maybe vsdrpCOM if you're using Primary Output). VS runs regasm at build time to extract the data, but I have a feeling it uses the /regfile option internally, and if so you won't see your custom entries. If that's the case, you could just add them in the Registry view of the IDE (and set AlwaysCreate for them) instead of using your ComRegisterFunctionAttribute code.
