Hi
i am getting following warning when i run my application. the project is to be registered as com interop.
Warning 2 "D:\My Codes\C# Codes\DataGen\Controlling Shell\DBConnectionWizard\bin\Debug\DBConnectionWizard.dll" does not contain any types that can be registered for COM Interop. DBConnectionWizard
can any one help
i would also like to know if there is any restrictions in com in .net like multi threading or certain complex controls
Hi,
Have u not exposed the interface or class as public
(Be sure that every interface and class have their own guids.)
Thanx,
Ch.T.Gopi Kumar.
Hi
Yes, i did make sure all classes are public and all are given seperate guid and progid.
it doesnt make any difference and error contnued.
when i tried to register the tlb with Regasm i am getting following error.
RegAsm : error RA0000 : Failed to load 'D:\My Codes\C# Codes\DataGen\Controlling
Shell\DBConnectionWizard\bin\Debug\DBConnectionWizard.tlb' because it is not a
valid .NET assembly
Hey,
R u trying to register the .tlb or .dll
Register the .dll using regasm and export the .tlb .
Thanx,
Ch.T.Gopi Kumar.
hi
i registered using dll..and it showed registration successfully.
when i checked in registry...only 1 out of 3 controls in that project was registered. rest of them was not registered.
i had given prog id and guid for all the classes.
i would also like to know what u mean by export tlb
Hi,
u can do registration and aswellas exporting the .tlb file for the assembly with regasm.That's what i mean to say.
Do one thing,comment the registered control code,and build and see if the second one has got registered or not.If not ,compare the code between control1 and control2.U'll get to know the error.
Thanx,
Ch.T.Gopi Kumar.
hi
