OCX uUid collision nightmare
-
Hi, if you know the answer to this one you can probably jump to the last paragraph, others might want to know more... I have run into a problem. I wanted to create an ActiveX control based on an existing one. So I took the entire Visual Studio project and copied it. Renamed all files (and names therein). And I modifed and registered the new control under the new name. No problem so far. Alas, I then noticed that the original control was gone. As soon as I registered the old or new control the other one was gone. I figured that the UUID was the problem here, (looks like this) //const GUID CDECL BASED_CODE _tlid = //{ 0x6fe77b28, 0x50c9, 0x4f53, { 0xb4, 0xe7, 0x13, 0x85, 0xe1, 0x4, 0x4b, 0x76 } }; These IDs are numerous in each project and in at least four different files, and sometimes they appear to refer to each other. I started to make new codes with GUIDGEN.EXE, but gave up because of the cross-referencing which was a bit obscure. My next idea was to create a new empty activeX project and copy all the IDs. The control registered nicely after a premature attempts, it does not delete the the other control, but fails to load into the test container. So, I have to create new IDs somehow. Either I made a mistake (despite double-checking) when copying from the empty project, or the IDs themselves contain implicit information about the control. If the ids contain no such info nor checksums and such stuff the best thing would be to back up to the previous working version and just change a single digit. Is this possible? Or, perhaps another problem is that my faulty attemps have left garbage in the registry (2K) which perhaps needs to be cleaned. I would be truly gratful for any help.

Perhaps the easiest solution would be to create a new ActiveX Control project from scratch, then add in all the files from your old project and tie them in to your new ActiveX "wrapper". (I have had to do this myself) ------------------------ Derek Waters derek@lj-oz.com
