I have a requirement to create an application which will accept the command line parameter. Depening on the parameter passed to the application, it will start and stop.
For Ex. on command prompt
C:\>MyExe start
This command will start the application for a given task.
C:\>MyExe stop
If MyExe is already running then the above command will stop it.
Appreciate your help.

What is the type of application ? Console, Win32, MFC, ...
Your question is not very clear.

It would be Win32 or MFC application

That will run a second instance of MyExe. You'll need to use IPC to look for a running instance and tell it to stop its work.

Thanks I think this will suffice my requirement

Create some gloabl object like NamedPipe, Mutux etc to manage single instance
Use PostQuitMessage to exit
|
|
|

Could you find a simpler way to solve your problem?
Example
C:\>MyExe start
write on a registry or on a fixed file
RUN = TRUE
and then the program will start
C:\>MyExe stop
write on a registry or on a fixed file
RUN = FALSE
and this instance ends
The first instance, thatsometimes (like into the OnIdle function) are checking the key , understands that he needs to be closed and .... close itself .
hope that helps

So what exactly is the question? You've given us a high-level overview, but nothing specific.

This is a poor solution as it involves polling and persistent storage.

Hi

I know that,... I according to you .
But the bettest (if exist ) solution depends on how complex is his program and how much time he coud spend on this problem.
My suggestion is only an example, he probally can adapt it to his program, or it can be a way to find a more simple way.
If not,...well he has many other ways, according to others resp.
Bye

And how are you sure that this is this code that causes the crash ? Use your debugger yo track the crash (press F5 to start and F9 to set breakpoints).

On first look there is no error in code, have check what line no is DEBUGGER showing you assertion!

CInternetSession session("My Session");
CHttpConnection* pServer = NULL;
CString tmpstr;
char inbuff[100000];
UINT nBytesRead;
CHttpFile* pFile = NULL;
try
{
void *szBuff=NULL;
CString URL=("http://www.yahoo.com");
BOOL bParse;
CString csSvrName;
CString csObjName;
INTERNET_PORT nPort;
DWORD dwServiceType = AFX_INET_SERVICE_HTTP;
bParse=AfxParseURL( URL, dwServiceType , csSvrName, csObjName, nPort );
pServer = session.GetHttpConnection( csSvrName, nPort);
pFile = pServer->OpenRequest(CHttpConnection::HTTP_VERB_GET, url);
pFile->AddRequestHeaders(pBuf);
pFile->SendRequest();
UINT nRead = pFile->Read(szBuff, 1023);
while (nRead > 0)
{
//read file...
}
delete pFile;
delete pServer;
}
catch (CInternetException* pEx)
{
LPTSTR lpszError=NULL;
//catch errors from WinInet
pEx->GetErrorMessagelpszError,1023);
}
if(pFile==NULL)
{
AfxMessageBox("Error in openurl");
}
else
{
nBytesRead=pFile->Read(inbuff,sizeof(inbuff));
tmpstr.Format("Read %d",nBytesRead);
AfxMessageBox(tmpstr);
}// endif
session.Close();

Please use your debugger to check where it crashes. Then, if you are not able to correct the problem, give us detailed information about the crash (where it crashes, what the problem is, ...)
