How to use tlb file into Visual C++?

[Ro-Man]

All the users of this particular forum has helped me out to fix the matter of mine. Well I am using the server application Com dll and I am having the client application through the VC ++. Let me know what should I use if I wanted to use the .h or _i.c files on the VC++ application so that I can have the access to the functionality of the COM dll. Let me know how can I have the above mentioned functionality. Any help on this particular matter would be highly appreciated. Thanks a lot in advance.

In order to get the requirement of yours I am suggesting that you should use the #import directive in to the application which you are supposed to do on the application of yours.

#import "MyCOMFile.tlb"

The above mentioned statement would create two separate files into the debug or release folder which is having an extension of .tlh and .tli. all these files can be used to define the com interface and smart pointer typedef declarations with the call CoCreateInstance for you can handle the reference-count automatically in the application.

Using the .tlb file into the C++ is not straightforward at as you do into the VB. However you can use the following code which would demo how can you use the type libraries into the VC++.

#import "MyPath\MyTypeLib.tlb" rename_namespace("SmthLooksMeNice") using namespace SmthLooksMeNice;
#include <objbase.h>
 
int main()
{
CoInitialize(NULL);
 

// Assume your COM object is named MyComObjectName
// and there is an interface IMyComObject.
// #import generated a smart pointer over that interface.
IMyComObjectPtr pObject(_uuidof(MyComObjectName));
 
BSTR temp = pObject->SomeProp;
pObject->DoSmth();
//...
CoUninitialize();
return 0;
}

I am hoing that the coding example which i have mentioned over here would be useful to get the requirement of yours.

Well the TLB file is used to describe the all the data of the COM server. However there would be no code into the TLB file. You need to register the COM server that is either exe dile or dll file into the executable module of the application which you are developing currently. Also make sure that you are importing the base class prior than you should use import the tlb file on the application of yours. So you should consider the thing which i have mentioned over here.

You should use the smart-pointer typedef is the name of the interface concatenated with Ptr. In case the If00 is the interface then the smart pointer type is the IF00ptr. As we have assume that the If00 is the interface the I recommend that the client code would like the below one.

#import "MyCOMFile.tlb" no_namespace

void main()
{
     CoInitialize(NULL);
     try
     {
         IFooPtr pFoo(__uuidof(Foo));
         pFoo->Method();
     }
     CoUnintialize();
}

So you should use get the idea from the thing which I have mentioned over here I am hoping that it would be useful to you.

Well looking at the matter which you have mentioned over here I am suggesting following thing which you can use to get the requirement of yours. I you can specify the prog ID and see whether it isn working or not. Well i am suggesting the following command which you can use as Prog Id I am hoping that it would be useful you.

#import "progid:Outlook.Application" named_guids

So try the same and let me know about the result.
