turn off /GZ option from the project settings, C/C++ tab
A better way is to correctly declare your function with its calling convention.
You have to chose between
__cdecl, __stdcall, __fastcall, or __thiscall calling conventions.

You need to know the exact definition of the function you are trying to call.
Then, when you use GetProcAddress, you should cast to result accordingly, and have a suitable function pointer to put the return value into.
WINAPI == PASCAL == __stdcall
If there's no calling convention used, it will be whatever was the default when the lib was built. In vc6, this will be __cdecl.
The symptom you describe means either your calling conventions are wrong, or there is a possibility that the called function (in the DLL) is trashing the stack in a specific way.

hi all,
i am trying to LoadLibrary and then getting the ProcAddress and trying to call that function in DLL.
I am getting the following error.
The value of ESP was not properly saved across fucntion call.This is usually the result of the calling the fucntion declared with one calling function with a function pointer declared with a different calling convention.
Any ideas .
TIA

Hi!!!
I am trying to check Internet connection on a system with the InetIsOffline().
But getting errors like
D:\Program Files\Microsoft SDK\include\IntShCut.h(220) : error C2065: 'IUnknown' : undeclared identifier
I have included intshcut.h and linked statically "url.lib". I am using VC 6.0 on Windows 2000 SP4 and IE6. Here is the code snippet
#include "stdafx.h"
#include "Wininet.h"
#include "stdio.h"
#include "stdlib.h"
#include "IntShCut.h"
nt APIENTRY WinMain(HINSTANCE hInstance,
HINSTANCE hPrevInstance,
LPSTR lpCmdLine,
int nCmdShow)
{
BOOL bConnected;
bConnected = InetIsOffline(0);
/*
Other code
*/
}
I am sniffing a linking problem but have no clue. I have put url.lib in Project /Settings/ Link / library modules.
Thanx in advance.

You should probably be including unknwn.h.

 Nope it does not work either.Still unable to link to intshcut.h.
The error this time
CheckInternetWithInetisOffline.obj : error LNK2001: unresolved external symbol __imp__InetIsOffline@4
Release/CheckInternetWithInetisOffline.exe : fatal error LNK1120: 1 unresolved externals
Error executing link.exe.
any more clues?

Sorry!!! My fault. It worked . I had removed url.lib from the list.
Thanx a lot.

if you change the Auto Insert Notification for the cd-rom player you need to reboot the system To make it work
switching it on or off is not very easy this way
It is possible to use a trick to avoid restarting windows
But I don’t have any clue how the trick works
Any idea ?

I imagine unloading and reloading the CD driver would accomplish the same thing. This is what Windows does, and more, when it is restarted. I'd hazard a guess that there must not be an easy way to reload drivers, otherwise, the CD's auto-notify feature would be using it.

The only problem I have is
That after I write the new value in to the registry
Windows don’t now the value is changed
So windows using the old value
\\Software\\Microsoft\\Windows\\CurrentVersion\\Policies\\Explorer
killing explorer.exe (ctrl + alt + del ) makes it work
I can’t use this option its making windows unstable
So the explorer.exe reloads the data from the registry

Right, and unless the program is coded to periodically check the registry, there's nothing you can do.

Hi,
My application access to a web service, using Visual C++ 6.0 and the Soap toolkit. Now I want to deploy it... the problem is that I don't know quite sure which things I have to install ( and install the full toolkit or the sdk doesn't seem to be a good idea ).
What should I install ?
MSXML4 ?
Mssoap1.dll ?
Mssmo.dll ?
Thanks in advance, greetings

Hello everyone,
May i know how to change the background color of an edit control upon a button click? I have added the WM_CTLCOLOR handler and i'm not sure on how to continue with the button click (I mean when i clicked a button, the edit control should change in color). I have found some sources which are not easy to understand. Your reply is greatly appreciated. Thanks!
///////////////////////////////////////////////////////////////
HBRUSH CTestDlg::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = CDialog::OnCtlColor(pDC, pWnd, nCtlColor);
if(pWnd->GetDlgCtrlID() == (int)IDC_EDIT1) // IDC_EDIT1-edit control
{
pDC->SetTextColor(RGB(0, 255, 0));
pDC->SetBkColor(RGB(0, 0, 0));
return (HBRUSH)(m_bkBrush.GetSafeHandle()); // m_bkBrush-CBrush
}
return hbr;
}

Hi,
the trick is to return the proper hBrush...
create a brush using your back ground color RGB(0,0,0) and then instead of returning
return (HBRUSH)(m_bkBrush.GetSafeHandle()); // m_bkBrush-CBrush
return the created brush
note: create the brush elsewhere (not in the OnCtlColor method, cause it is called 1000000 of times)
hope this helps ya
Yaron

Thanks Yaron for your help. I got it in microsoft visual c++ 6.0. However, when i tried this method of changing color in edit control in microsoft visual c++.NET, i am still unable to change the color in the edit control. Do anyone here knows how to insert a message handler - for instance:WM_CTLCOLOR in microsoft visual c++.NET? C++.NET platform does not have the classwizard, therefore beginners might find it difficult to start up with. Anyway, those who might have trouble with the edit control can refer to the link below:

Thanks for your help and replies! Thanks everyone!

Hey dudes,
I hope someone out there can make sense of this...
I have plenty of experience with sockets programming,
but I can't seem to figure this out.
I've just added some network code to an open source game,
and everything is working fine except the sockets callback.
I'm reusing old code that works perfectly and the callback
function received events instantly, whereas inside the game
it's lucky to receive it 20 secs late, if at all.
I can slow down the frame-rate to an unplayable 9 fps, then
all the callbacks run, but 4-5 secs late.
Does anyone have any ideas?
Does the CPU usage affect sockets callback?
I'm using Visual C++ on Windows environment, and using
WSAAsyncSelect for my callbacks.
Any help would be greatly appreciated.
SLY.
