Ok, VC++ tells me the same errors all the time:
MSVCRT.lib(MSVCRT.dll) : error LNK2005: _sprintf allready defined in LIBCD.lib(sprintf.obj)
As far as I understand it, it is a problem with incompatibel iostream librarys. VC++ chooses the right version itself but now there is a conflict since I build something in that requires different iostream versions.
I put some png reading code in my previous well working project. I used the same code in another project without any trouble. But last time it was an MFC application and now it is a simple VC++ win32 application project.
Maybe the way I linked the library caused some trouble too. I had to use that methode:
extern "C" <br />
{<br />
#include "png.h"<br />
#include "pngconf.h"<br />
}
other includes are
#include "ddraw.h"<br />
#include "windows.h" <br />
#include "windowsx.h"<br />
#include "mmsystem.h"<br />
#include "iostream.h"<br />
#include "conio.h"<br />
#include "stdlib.h"<br />
#include "malloc.h"<br />
#include "memory.h"<br />
#include "string.h"<br />
#include "stdarg.h"<br />
#include "stdio.h"<br />
#include "math.h"<br />
#include "io.h"<br />
#include "fcntl.h"
How can I get rid of this annoying link errors? Every help is welcome.

MSVCRT is a release version (MSVCRTD is the debug version)
LIBCD is a debug version (LIBC is the release version)
so, it looks like you're mixing release and debug versions of your app and LibPng. make sure you link debug to debug libraries and release to release.

I just tried something and could fix the problem for the moment.
I changed the compiler argument from /MLd to /MDd for debugging and /ML to /MD for release. Now I only got a last warning for MSVCRT.lib (only debug mode):
LINK : warning LNK4098: Standard library "MSVCRT" is in conflict with another library; /NODEFAULT:Library used
(sorry, I have to translate all messages since I did not use the englisch localisation, so the warning can look different from the one you get)

In the properties of your project, try to specify libcd.lib (and perhaps libc.lib as well) in the field entitled Ignore Specific Library, in the tab Linker > Input.

Hi everybody!!
I have to call a function "PutData()" each :
- 2 seconds.
- Every time OnDraw() is called (event)
For that I must use "WaitForMultipleObjects" to call PutData() every time one of the two events above happens.
My problem is how can I synchronize (I think I need a handler as I've seen in MSDN) the event that means that OnDraw() has been called with "WaitForMultipleObjects"???
Thanks you very much.

No, you don't.
Set a timer every two seconds, and call PutData in OnDraw, and when the timer fires.

in my app, i use CreateProcess() to launch a command.com.
but, I can not find the program from "Process view", instead, I find 2 other programs:
1) Redir32.exe
2) Winoldap.exe
could someone explain why command.com is not launched? what are the 2 exe used for?

Command.com is a part of good old DOS. Windows 95/98/ME also have it for the command prompt. Its something like cmd.exe(Command Prompt) in Windows 2000/XP.
Since .com files are deprecated in Win2K/XP, Windows has to emulate a Virtual DOS Machine(VDM) in order to be able to run command.com. As a matter of fact, you are running a VDM instead of command.com when you are executing command.com, and Redir32.exe and WinOldAp.exe are parts of VDM and that's what Windows "Process view" sees instead of command.com.
Hope it helped.

The dll I wrote which has some shared data segment that being used by mutiple exes compiled on 32bit compiler and it worked. However, as I compiled the same project using the amd64 compiler by microsoft SDK 1415 and tested on x64 system, the shared data doesn't seems to be working anymore(each exe seems creates its own copy of those variables). I am wondering is there something changed on amd64 compiler that I did not notice. Anyadvice will be appreciated. t
This is how I did to create the shared variables
#pragma data_seg(".timerTOD") // shared with all procs
struct something
{
double a
int b
} variable_name = {0};
#pragma data_seg() // back to normal data
#pragma comment(linker, "/SECTION:.timerTOD,RWS")
|
|
|
|

Don't know if it will help, but we use the
#pragma data_seg( ".MyName" )
in the source file and
SECTIONS<br />
.data READ WRITE<br />
.MyName READ WRITE SHARED
in the module's definition file.
Maybe the AMD compiler/linker does not know the pragma
#pragma comment(linker, "/SECTION:.timerTOD,RWS")

Are the exes and the dll all compiled with the 64-bit compiler?

Hi!
My application is automatically started when Windows is lauching. Sometimes Shell_NotifyIcon will fail. I do not have an error code since I haven't been to reproduce that bug very often.
My guess is that the desktop is not ready or something. Do you think that it would be safe to do something like:
BOOL bRes;
do
{
bRes = Shell_NotifyIcon(...);
}while(bRes = FALSE);
Thanks!

I can't remember it exactly (it's in my BugReporter article here on CP), but there's a way you can register a message to notify you when the taskbar gets repainted so that you can put the icon back in the system tray. Otherwise, when explorer.exe crashed and restarted, my icon would be gone from the system tray.
I don't know if that helps any, but I tried.

No. If there's an error with your input you'll have yourself a nice little infinite loop.
I had this happen to me last night, although it happened for all programs. It turned out I had a virus, so I did a system restore and it's all good now . I doubt that's your problem though.
I've never had any problems with applications I've written doing this. I've heard of a few programs that add a few seconds delay during their startup to give Windows time to initialise properly. That might cure the problem. Other than that, there's not much you can do other than verifying that your input is correct.

Hi,
I utilize Visual C++ .NET 2003 with MFC.
When I open a file, MFC works with Serialize(CArchive& ar) method.
ar is created by the MFC framework.
If I want to specify the initial directory in the open file dialog box, I have to set it with the member lpstrInitialDir of the OPENFILENAME structure.
My question is how to create the ar CArchive type to be able to call the Serialize method generated by MFC ?
Thanks,
Claude

Can anybody help me to find detailed information about "Win32_PerfRawData_PerfProc_Thread"
class Win32_PerfRawData_PerfProc_Thread : Win32_PerfRawData
{
string Caption;
uint32 ContextSwitchesPerSec;
string Description;
uint64 ElapsedTime;
uint64 Frequency_Object;
uint64 Frequency_PerfTime;
uint64 Frequency_Sys100NS;
uint32 IDProcess;
uint32 IDThread;
string Name;
uint64 PercentPrivilegedTime;
uint64 PercentProcessorTime;
uint64 PercentUserTime;
uint32 PriorityBase;
uint32 PriorityCurrent;
uint32 StartAddress;
uint32 ThreadState; !!!
uint32 ThreadWaitReason; !!!
uint64 Timestamp_Object;
uint64 Timestamp_PerfTime;
uint64 Timestamp_Sys100NS;
};
Microsoft provides only very limited information about "ThreadState" and "ThreadWaitReason"
I need to find out why paticular thread in other application is waiting.
Thanks
Alex.

Per MSDN, there are at least 21 values that ThreadWaitReason can have. Likewise, ThreadState can have one of eight values.

Hello:
I had to take my work home last night. So, I just copied the entire project and it's folder onto my flash drive. When I got home and opened it up, there were errors about class redefinition. I discovered that AFTER I made changes to a copy I made and received an INCREDIBLE amount of errors.
Now I'm back at work, and I've verified the code builds up just fine. But when I copy the project folder and open up the solution, it again fails to build, saying that I'm redefining classes.
Would anyone know a workaround, besides copying raw code over and creating multiple projects?
Thanks!

Gosh I feel like blushing.
I was searching around more and decided to try ShowIncludes, to see what the project was doing.
Apparently somehow my includes got out of order. Changed that, watched as it worked fine.

I have done some experimentation.
It appears that there is a bug in Visual C++. Make a copy of a perfectly working project, and it will not compile. It will give you errors about class redefinitions and invalid types.
Now, turn on the Show Included Headers option, under the Advanced C/C++ Project settings. Compiles fine.
Weird.

This must not be a Visual Studio v6 issue as I've never seen it.
