Arrrgh I cant do it :( How clever are you??

[rudvs2]

Hi all

I am running win 2k

Now i have been helpfully given a reference in c++ to a wonderfull little function in mapi32.dll

I can use dependancy walker to view the function but to get any details on the function eg aliases it may be under or any other such info i need quikview which does not ship with win 2k and is not supported

what I need to know if there are any gurus out there is where i can find the info i need to convert this function into a usable API call for vb

here is the c++ info on the function

Quick Info
Header file: MAPIUTIL.H
Implemented by: MAPI
Called by: Client applications and service providers


SCODE ScLocalPathFromUNC(
LPSTR szUNC,
LPSTR szLocal,
UINT cchLocal
);

Parameters
szUNC
[in] A path in the format \\[server]\[share]\[path] of a file or directory.
szLocal
[out] A path in the format [drive:]\[path] of the same file or directory as for the szUNC parameter.
cchLocal
[in] Size of the buffer for the output string.
See Also

and here is what i have in vb so far

Declare Function ScLocalPathFromUNC Lib "mapi32" (ByVal szUNC As String _
, ByVal szLocal As String, ByVal cchLocal As Integer) As Integer

However when i execute the call it says header entry not found

I know that the call is in mapi32 but it has a @12 after the name so i am assuming it must be able to be called with an alais to it. But blowed if i can work out what that might be

So please calling all gurus lets see how clever you all are

Not sure what you are saying, but there is a MAPI Control in VB. Look in the Component dialog box.

[rudvs2]

That is no good to me hellswriath for the following reasons

Mapi control in vb uses only a limited number of the functions contained in Mapi32.dll

None of those functions does anything close to what the function does that i am after

That is why i am having to try to convert the information over to a vb api call

I know it can be done

I just need 1 little peice of info and i should be away

Write a dll in C++ containing that function (I have never done this).

Well I would ................. only I dont know the first thing about c++ so that blows that theory out of the water

Any other ideas gents??

[rudvs2]

anybody ??

[Kaverin]

Since the function uses strings, it probably has both a unicode and ANSI form. Try to alias the function as ScLocalPathFromUNCW (unicode) or ScLocalPathFromUNCA (ANSI). One of those may work.

[rudvs2]

thanks for the advice Kaverin I tried both options but no joy

[rudvs2]

okay I have now got it Finding and executing the API Function. I am getting an Integer Value Returned (which i assume is an error code of somesort) So it appears to be working

here is the functioning API Declaration For any one who is interested

Declare Function ScLocalPathFromUNC Lib "mapi32" Alias "ScLocalPathFromUNC@12"  (ByVal szUNC As String _
, ByVal szLocal As String, ByVal cchLocal As Integer) As Integer

Thanks for the inspiration kaverin
