Hi experts
I have a dll file .First i used it in c# application it works fine.
But i want to use it in c++ program .I use "dumpbin" command to see the function provided by dll.
but it shows only 9 function (not seen in c#)although in c# i have seen number of function .what is problem.
one thing more "dumpbin" command also shows that this is not a class based dll.

so tell me the below qurries:
1.What is the procedure to use a dll in c++ program
2.how can i use that functions that is used in c# application.

Thanks

i use explicit linking
like this

typedef UINT (CALLBACK* LPFNDLLFUNC1)(void);

HINSTANCE hDLL; // Handle to DLL
LPFNDLLFUNC1 lpfnDllFunc1; // Function pointer

hDLL = LoadLibrary("MyFile.DLL");
if (hDLL != NULL)
{
lpfnDllFunc1 = (LPFNDLLFUNC1)GetProcAddress(hDLL,
"DLLFunc1");
if (!lpfnDllFunc1)
{
// handle the error
FreeLibrary(hDLL);
return SOME_ERROR_CODE;
}
else
{
// call the function
uReturnVal = lpfnDllFunc1(void);
}
}

But using "dumpbin" i saw the function that are never seen by me in c# application.Here (c++)it shows only 9 function that are not useful for me.How can i use function that are used by me in c# application by same dll

i am also sending some c# code plz suggest me to use in c++

Redemption.RDOSessionClass Session=new Redemption.RDOSessionClass();
Session.Logon("",0,0,0,0,0);

Redemption.RDOStore NewStore=(Redemption.RDOStore)Session.Stores.AddPSTStore(@"c:\temp\PST1.pst",null,"New PST");

Redemption.RDOFolder NewFolder=NewStore.IPMRootFolder.Folders.Add("Parshant",null);

You are right here. Is this code is failing for you ? If yes, where ?

Redemption.RDOFolder NewFolder=NewStore.IPMRootFolder.Folders.Add("Parshant",null);

Looks like use defined classes. What you are trying to do here ?

Is this dll is created using C#(class library) ? If yes, not sure, If how/it is possible to use in VC++.

You can get some help from C#[^] forum.

Well I figured it out:

You can create a file handle on the folder -- and set the sharing for read and write, but not delete.

m_FolderHandle = CreateFile(m_FolderName, FILE_LIST_DIRECTORY, FILE_SHARE_READ|FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL );

closing the handle will unlock the folder.

I guess I didn't specify -- that I needed to only maintain the lock while my application is running...

I'm not clear about your requirement, Can you use IClassFactory::CreateInstance ?

I have two coClass under a TypeLib. When I call coCreateInstance() method, it reciprocates with one of the default coClass in TypeLib. I can call methods & properties of default class but if i have to change to another coClass, how can i do that?.

example:
TypeLib has coClass1 and coClass2.
Using IDispatch interface, I can call the default coClass1 and its methods can be invoked.
IDispatch->Invoke()-->it executes default coClass1 methods & properties.

But, if I want to execute coClass2 methods & properties, how can i proceed?

I hope now you are clear about my requirement.
Thanks in advance.

It gives you interface(coclass) you requested.

praveen kumar agarwal wrote:

You need to use CoCreateInstance for different classes.
i.e. you need to call CoCreateInstance again for different interface, as it will have different CLSID.
