I agree, but i am just the employee. I have been doing maintenance on existing C++ systems with little problems. Maybe that’s why. But it is something different to start from scratch. I really wanted to get this right.
Thanks for the help.

Can you just tell me how do i create the Executable?

You've already been told...at least twice. What more do you require? If you are not going to heed our suggestions, stop asking for help.

People already told you how to do that (David for instance). But, then ? You will end up an executable that doesn't do anything with the dll and there's no point in that. You will need to add code to load the dll and call some functions but in order for us to help you, you'll need to learn at least the basics of C++ and visual studio.
You think creating an executable is just a matter of clicking there and there and BAM, magically your executable doing what you want is created ?

To be fair, he might be working with a VB executable

It depends because it could even complicate things a lot (for instance if he needs to pass strings or objects to a dll function).

Can't you just create a "dummy" Win32 project that links to your DLL?

blokkies, let me try to summarize what's going on
What is a DLL?
A DLL is a block of useful code that can be loaded by several programs at once
Why would I make one?
Because you want a modular solution. A reusable, easy to update solution.
What is a DLL again??
It is something that one or several actual programs might find useful. It is not a program by itself. You could think of it as a class, if you really wanted to.
What's a program?
... Well a program is a block of code that a human might find useful.
So a DLL is not a program?
Correct :)
So humans use programs, and programs use DLLs?
Right again!

Is your project used in the program? You say that you're doing mainainance, right? In this case the code you want to debug is already used in your program.
There is sufficient light for those who desire to see, and there is sufficient darkness for those of a contrary disposition.

Hello everyone .
i am trying to import a COM file in vc++ project but the generated .tlh file from the com file seems to have an inherit errors , i successfully added #import directive in my stdafx.h file with the full phyiscal path to my com file then i included stdafx.h into my stdafx.cpp file , then i compile
the studio generates for me a .tlh file but that file seems to have errors in it .
the following code in the generated .tlh file has the problem
<br />
struct __declspec(uuid("92d8ec9e-550e-4525-a858-c8601ad50703"))<br />
_VoiceNumbers : IDispatch<br />
{<br />
<br />
<big>__declspec(property(get=GetVoiceNumbers))<br />
_CollectionPtr VoiceNumbers;</big><br />
<br />
<br />
long Count ( );<br />
HRESULT Delete (<br />
long Index );<br />
HRESULT Add (<br />
struct _PhoneNumber * oAdd );<br />
_PhoneNumberPtr Item (<br />
long Index );<br />
IUnknownPtr NewEnum ( );<br />
_CollectionPtr GetVoiceNumbers ( );<br />
<br />
<br />
virtual HRESULT __stdcall raw_Count (<br />
long * _arg1 ) = 0;<br />
virtual HRESULT __stdcall raw_Delete (<br />
long Index ) = 0;<br />
virtual HRESULT __stdcall raw_Add (<br />
struct _PhoneNumber * oAdd ) = 0;<br />
virtual HRESULT __stdcall raw_Item (<br />
long Index,<br />
struct _PhoneNumber * * _arg2 ) = 0;<br />
virtual HRESULT __stdcall raw_NewEnum (<br />
struct IUnknown * * _arg1 ) = 0;<br />
virtual HRESULT __stdcall get_VoiceNumbers (<br />
struct _Collection * * _arg1 ) = 0;<br />
};<br />
the bolded code part has the problem and the following errors are
<br />
Error 1 error C2146: syntax error : missing ';' before identifier 'VoiceNumbers' d:\hitech work\jniwork\testingrex\testingrex\debug\resumemirror.tlh 893 TestingRex<br />
Error 2 error C4430: missing type specifier - int assumed. Note: C++ does not support default-int d:\hitech work\jniwork\testingrex\testingrex\debug\resumemirror.tlh 893 TestingRex<br />
Error 3 error C2208: 'ResumeMirror::VoiceNumbers' : no members defined using this type d:\hitech work\jniwork\testingrex\testingrex\debug\resumemirror.tlh 893 TestingRex<br />
Error 4 fatal error C1903: unable to recover from previous error(s); stopping compilation d:\hitech work\jniwork\testingrex\testingrex\debug\resumemirror.tlh 893 TestingRex<br />
<br />
i am trying to make a wrapper for that com file to be able to call it from java using JNI technology .
each time i try to solve the errors , and compile again the studio generates for me another .tlh file as earlier one that has the same errors and i don't know what to do .
anyone has any solution for that please

Sounds like it has dependencies on another COM object.
Try adding 'auto_search' to your #import statement - that will attempt to resolve dependencies such as this without you having to alter your code by implicitly importing the other libraries that are required:
#import "some-comm-item" auto_search
HTH!

i did that but it gives me the following errors
Error 1 error C2059: syntax error : '(' d:\hitech work\jniwork\testingrexx\testingrexx\debug\msvbvm60.tlh 483 TestingRexX
Error 2 error C2059: syntax error : '(' d:\hitech work\jniwork\testingrexx\testingrexx\debug\msvbvm60.tlh 925 TestingRexX

Well - that tells you where the CollectionPtr comes from - it's a VB thing. OK, in that case you can explicitly define CollectionPtr yourself (look at how it's defined in the msvbvm60.tlh file) and remove the auto_search from the #import statement.

please my friend , can you explain in more detail i am not c++ savvy
be patient please with me
i searched that file but i didn't find _CollectionPtr
i found that
struct __declspec(uuid("a4c46780-499f-101b-bb78-00aa00383cbb"))
_Collection : IDispatch
{
//
// Wrapper methods for error-handling
//
_variant_t Item (
VARIANT * Index );
HRESULT Add (
VARIANT * Item,
VARIANT * Key = &vtMissing,
VARIANT * Before = &vtMissing,
VARIANT * After = &vtMissing );
long Count ( );
HRESULT Remove (
VARIANT * Index );
IUnknownPtr _NewEnum ( );
//
// Raw methods provided by interface
//
virtual HRESULT __stdcall raw_Item (
/*[in]*/ VARIANT * Index,
/*[out,retval]*/ VARIANT * pvarRet ) = 0;
virtual HRESULT __stdcall raw_Add (

You won't find that explicitly. You'll find something like COM_SMARTPTR_TYPEDEF(_Collection, __uuidof(_Collection));

how can i redefine explicitly that struct my friend , i don't get you well

i am sorry my friend , i found that
struct __declspec(uuid("a4c4671c-499f-101b-bb78-00aa00383cbb"))
Collection;
and that
_COM_SMARTPTR_TYPEDEF(_Collection, __uuidof(_Collection));
so what can i do by this thing now

Put these two lines:
struct __declspec(uuid("a4c4671c-499f-101b-bb78-00aa00383cbb"))
Collection;
_COM_SMARTPTR_TYPEDEF(_Collection, __uuidof(_Collection));
in your .cpp file before the #import line.
You probably need the definition (as opposed to declaration of _Collection as well - is there another definition of _Collection later in the tlh file, or in the tli file? If so - you need that

Where can i put that line my friend
?
_COM_SMARTPTR_TYPEDEF(_Collection, __uuidof(_Collection));
in Resumemirror.tlh
just before the line with the error or where exactly ????

I had the same problem importing msado15.dll,
a solution was found on some Chinese forum[^], adding rename("EOF", "adoEOF") on the end of the import statement line
for example,
#import "c:\program files\common files\system\ado\msado15.dll" no_namespace rename("EOF", "adoEOF")
In my case the error was raised on a line inside msado15.tlh with folowing code
__declspec(property(get=GetEOF))
VARIANT_BOOL EOF;
So i suppose the conflict was on EOF being defined multiple times, and the rename solves this.
HTH,...

Yes, I discovered that was the root cause as well - it was the same issue with the VB run-time - it defines EOF as well. I'd have found that out if I'd made a little sample app (as I often do), but as I do not have (and, given the opportunity, will never have) VB6 on my machine, I thought I wouldn't be able to import the VB6 run-time. I must confess that I decided not to post this alternate solution, as the OP seemed...satisfied, and I don't like adding confusion 
Thanks for your post, anyway!
