I got a project made to address Microsoft CryptoAPI but can't compile it. Seems, it can't recognize any declaration in wincrypt.h (I've verified that the wincrypt.h and Crypt32 library is in the right place).

I'll try to find on the code project, that suggest to define this:
#define _WIN32_WINNT 0x0400
or this:
#define _WIN32_WINNT 0x0500
#define _CRYPT32_
but neither is working

Google search said that we might have to install newer platform SDK. Does anyone has a clue of using it ? If it's really because of SDK, where to get it (I never used SDK before) ?

Not sure about the problem with the Crypto API not compiling, what errors are you getting back from the compiler?

You can download[^] the lastest Platform SDK straight from the MSDN site, just hope you're not on dialup as it's just under 400mb's Smile | :)

Here are a parts my error (the first line, I'm using something from wincrypt - see at the end):
:\test crypto\certmanager\certificate manager v3.2.2\lcertcontext.h(24) : error C2146: syntax error : missing ';' before identifier 'CreateCardList'
d:\test crypto\certmanager\certificate manager v3.2.2\lcertcontext.h(24) : error C2501: 'PCCERT_CONTEXT' : missing storage-class or type specifiers
d:\test crypto\certmanager\certificate manager v3.2.2\lcertcontext.h(24) : error C2061: syntax error : identifier 'HCRYPTPROV'

I've tried to find in MSDN.com, but can't find it. Could you please give me more clue about how to find it (link, keywords, or whatever) ? I don't mind about the size Smile | :)

And here is a part of my code, including my define:

#define _WIN32_WINNT 0x0400
#include <stdio.h>
#include <windows.h>
#include <wincrypt.h>
#include "Resource.h"

#define MY_ENCODING_TYPE (PKCS_7_ASN_ENCODING | X509_ASN_ENCODING)

class lCertContext
{
public:
BOOL FillListCtrl(CListCtrl *List,int *ListIndex);
PCCERT_CONTEXT CreateCardList(HCRYPTPROV hCSPCard,DWORD dwFlag, LPTSTR szCSPname);
}

The missing 3 includes from my previous reply are (because of 'tag' like) - in the order:
stdio.h, windows.h, wincrypt.h

Weird, just tried building it from here and it works fine. Just check your defines are being made before you link to the include files, ie...

#define WINVER 0x0400
#define _WIN32_WINNT 0x0500

#include <windows.h>
#include <wincrypt.h>

Looking at the wincrypt header if dont use them anyways though.

You can download the Platform SDK from here[^], theres a section at the bottom that says 'Files in this download', just select the exe for your processor type, probobly x86.

Once you've downloaded the SDK (check you download all the samples as well as they can be quite helpful at times) try building one of the WinCrypt samples and see if that works.

The link you provided doesn't support VC++ 6 (seems Ms never care that millions people are still using the old good VS6). But anyway, I got it from a friend (after asking to many people Frown | :(

... and it's compiling perfectly. Thanks for your help anyway.

You have to install a hook. Messages are always sent to their target windows (or threads). Imagine the havoc it'd cause, if every message was broadcasted to every window out there.

Hello everyone,

I have written a configuration wizard in c++ (mfc) that works great on windows xp. I would like to use this application on a windows xp embedded system.

How would I go about creating the executable with no dependencies that will run on an xp embedded system? It is my first time working on an embedded application, so any help would be appreciated.

I have tried google, but I haven't had any luck finding a good tutorial.

Thanks in advanced.

I think I might have stated my problem incorrectly. The problem is not the dependencies, the problem is that I want to be able to run the wizard on a windows xp embedded system, but it won't work if I just try to run the same executable that works in windows xp.

Are there settings that have to be changed in VS 2003 to make the exe work in xp embedded?

Thanks for the help,

ah, yeah, you mean if you compile for a target, and execute on another plateform ?

in fact you have to cross compile, but i'm not sure this can only be made with a project settings change...
