Are you sure it still runs in the background?How do you term it as "hides" ?
And is it a console application?

Thread abnormal behavior

Dear all
I Write a Multi threaded program which is responsible to read data from hardware and analyse it.
When I run the program all of threads work properly.
But after a while, one or some of threads die and no information is available from their state. ( I log live state of threads in a file. )
This abnormal behavior is computer dependent. On some computers I see such behavior but on another one, program works properly.

Do you know what is the reason of this problem.

Best Regards
Mahdi

if the thread is dying abnormally then it is posible that the OS is distorying the thread coz the thread might have gone into endless recurrsion.

So well does the thread disappears or does it end normally i.e the thread function returns normally.

yes you should, may put a breakpoint at the end of the function, or put some trace logs if you have them.

At the end of your thread loop, add a message box

<br />
your thread function<br />
{<br />
<br />
do<br />
{<br />
}while(xState=true);<br />
AfxMessageBox("I'm Done");<br />
<br />
}<br />

This is a simple way to test if it's getting out of the loop which also says that the thread is terminating.

Use a debugger and get a stack trace of what the thread is doing when it hangs.

The CCS_LEFT (or CCS_RIGHT) styles will make it vertical on the left or right edge.
The TBSTYLE_WRAPABLE style will allow multiple rows of buttons.

ToolBar controls are windows so you can move/resize them with MoveWindow(), etc.
THere are messages to get button sizes so you can ccalculate the dimensions required to get
two rows of buttons. It's all here in the SDK...

Is LPTSTR a char pointer?

Hello everyone!
I'm debugging a program, and, I'm viewing my own binary file in a hex editor for the first time, and that somehow makes me happy... (#define __NO_LIFE_GEEK__) Laugh | :laugh:

Now... Until byte 8 it's alright, but after that it's supposed to write a LPTSTR containing the following text:

You need a SSE2-enabled processor in order to run this program.

However, the 9th char is 03h, which doesn't look like a Y (59h)... I'm writing it like this:

// Get text in CEdit
m_em_errorMsg->GetWindowText(_tempString, m_em_errorMsg->GetWindowTextLength());

// Write it
out.Write(_tempString, m_em_errorMsg->GetWindowTextLength());

(_tempString being the LPTSTR)

So I was wondering if I should write it some other way... Am I wrong? Thanks! Laugh | :laugh:
