Don't use SuspendThread. See here[^] for details.

SuspendThread might be failing with an error.

Put this line of code directly after the call to SuspendThread:

DWORD Error = GetLastError();

Then, inspect the Error value to learn what Win32 error occured.

You can look up the error code in the program "errlook" provided with the platform SDK.

In addition to Stephen's reply, you can read about the same problem here[^].

The only sane place to suspend a thread is from the thread itself.
Use may use an event or a volatile declared boolean, or a user message if it's a UI-thread, to instruct the thread to suspend itself.

you can use AfxEndThread()
or
KillThread()

or you can send a notification to a thread to exit

Hi guys

Does anybody know what the equivalent of ldexpl() is in C#.Net?

Any pointers would be appreciated.
Thanks.

Hi i have one doubt regarding how to generate XML file output for example;

main()
{
int Array_sample[];
for(int i=0;i<=10;i++)
   {
      Array_sample[i]=i;
      std::cout<<Array_sample[i]<<std::endl;
//This is generating output but i want to write this output only print in
  // XML file how do that???
   }
return 0;
}

Thanks and Regards

#include <iostream>
#include <c++/3.4.5/fstream>

using namespace std;

int main()
{
int Array_sample[10];
fstream myOutput;

myOutput.open("test.xml", fstream::out);

myOutput<<"<?xml version=\"1.0\" encoding=\"Windows-1252\"?>"<<endl;
myOutput<<"<numbers>"<<endl;
for(int i=0;i<=10;i++)
{
Array_sample[i]=i;
myOutput<<"\t<item>"<<Array_sample[i]<<"</item>"<<endl;
}
myOutput<<"</numbers>"<<endl;
myOutput.close();

return 0;
}

[EDIT:] screwed-up the quotation marks. They're fixed now.

I'd normally be more polite, but you sir nisha0000, are a donkey!

It creates test.xml as it's output. For ****'s sake - try actually compiling it.

Something like this:

CDateTimeCtrl* pCtrl = (CDateTimeCtrl*) GetDlgItem(IDC_DATETIMEPICKER1);
ASSERT(pCtrl != NULL);
pCtrl->SetFormat(_T("MM-dd-yy"));

//Also check COleDateTime::SetFormat
