prefer ::ShellExecute() or ::CreateProcess() than system()

There is no in build function to do that i believe.

One approach could be starting a new instance of the current application and then exit the current instance (some more inteligence can be given to the application through the command line parameters like to wait till the parent application has cleaned-up the resource and exited properly before initializing the new instance).

Use Create Process.
I have tested it with a dialog based app. Maybe you must use some startup time delay to wait until the calling application is closed. For more information about CreateProcess have alook in the MSDN.

void CRestart_selfDlg::OnButtonRestart()
{
STARTUPINFO m_StartupInfo;
PROCESS_INFORMATION m_ProcessInformation;
ZeroMemory(&m_StartupInfo, sizeof(STARTUPINFO));
ZeroMemory(&m_ProcessInformation, sizeof(PROCESS_INFORMATION));

char* szPrgPathName = "\"restart_self.exe\"";
CreateProcess ( NULL
, szPrgPathName // the commandline options
, (LPSECURITY_ATTRIBUTES)NULL
, (LPSECURITY_ATTRIBUTES)NULL
, FALSE
, CREATE_NEW_CONSOLE
, NULL
, NULL
, &m_StartupInfo
, &m_ProcessInformation) ;
DWORD dwLastError = GetLastError(); // for test only

// close now the dialog based application
OnOK();

// should work in view based application, not tested
// theApp.CloseAllDocuments(TRUE);
}

You might require to install the chinese font using the windows installation cd. ( through control panel-> Regional Settings you can achieve this i believe)

Create "Resource-Only DLL", In these DLL's you can copy all the chinese strings (All Resources) and call the specific DLL as your requirements.

I feel it should work.

I don't know if this helps but what if you add this to your .rc file:

LANGUAGE LANG_CHINESE, SUBLANG_CHINESE_SIMPLIFIED
#pragma code_page(936)

heyhey
wow, I love this forum! hopefully someone can help with my question:
I, like many else, try to write a stable math library in VC++.
unfortunately my vector struct makes some trouble so here's the code:

...

__declspec(align(16)) union vector4{<br />
	__m128 m128;<br />
	struct {	<br />
		float x,y,z,w;<br />
	};<br />
	float  f[4];<br />
};<br />
<br />
...<br />
int main()<br />
{<br />
  vector4 a;<br />
  a.x = 1.0f; a.y = 0.0; a.z = 0.0; a.w = 1.0;<br />
  vector4 b = {1.0f, 0.0f, 0.0f, 1.0f};<br />
  a.f[0] = 1.0f; a.f[1] = 0.0f; a.f[2] = 0.0f; a.f[3] = 1.0f;<br />
  return 0;<br />
}<br />

any of those lines work fine but on exiting I get a
"Unbehandelte Ausnahme bei 0x004117a7 in MatheFunktionen.exe: 0xC0000005: Zugriffsverletzung beim Lesen an Position 0x00000800."
<=>
"unhandled exception at0x004117a7 in MathFunctions.exe: 0xC0000005: Access violation while reading at position 0x00000800."

Removing the declarations a = ... a.x =... and stuff solves the problem. Do I have to free the memory of a before quitting?

I'm using Visual Studio 2005 8.0.50727.42
any help is apprecitated

PS: I already googled and searched the forum but couldn't find a solution, so links would be appreciated, too

No I changed it to :

<br />
__declspec(align(16)) struct vector4{	<br />
		float x,y,z,w;	<br />
};<br />

and still fails, the error seems to lay within the
__declspec(align(16))
cause when it's removed it works

No, you dont have to.

I'm able to run this code without any error. Is something other you are trying , than mentioned here.

BTW, hope you have read this MSDN line The __m128 data type is not supported on Itanium Processor Family (IPF) processors.

hm, yeah you're right...
somehow the cpuid-test whether sse exists failed before but didn't throw an exception when run alone.
When I declared my vector and run the prog as said it failed at the end somehow.
whatever I changed my sse-test (not pure asm) and it worked. Thanx anyways!!!

Is GetProcessTimes helpfuls?if no and you want a good example you find your answer on examples of MSDN If I remember its name is PVIEWER(not sure) but its very good example you can see detaily of each process that is detailed but also you can see a good example on the codeproject of David Crow here[^]
