you can traverse thorough the list to see if the element you are going toinsert already exist or not.
if it exsist dont insert.
otherwise insert.

Hi,
I have a Listcontrol which is populated with data.. I need to save all the data into a file (file type is not specific). on clicking a save button. Can I have a code snippet for this.

Thanks

where exactly are you getting the problem.
in getting the data from the list control or in saving the data to a file or both.
roughly, the algo should be something like this.
<pre>int n=m_list.GetItemCount();
FILE *fp;
fp=fopen("data.txt","w");
for(int i=0;i<n;i++)
{
m-list.GetItemText(i,&str);
fprintf(fp,"%s\n",str);
}
fclose(fp);</pre>

Why do you need the code? I mean, what is your trouble about? Make an iteration writing every item data to the file.

Hi all,

I have trouble in parsing the XML Schema(XSD) file with the MFC VC++ dialog application. Please provide me an sample source code for parsing/traversing the XSD (XML SChema) with the MFC VC++ code. I need to extract all the tags(Elements, attributes, group elements,attribute groups, and etc) of the xsd with the MFC.

you're going to have to delete the virus first or else it'll keep reloading the .exe process. focus on cleaning your system not on terminating the process

i cannot delete that exe as it is running.

deleting the exe will NOT get rid of the virus... its never that simple. Use proper antivirus/antispyware software(s) to scan your system and use it/them to delete the virus.

i once got this same type of issue.
by hit and error, first i deleted another process which creates this process. then i remembered that parentprocess name and repeated the same each time i booted my pc.
i suggest you to find out the process that creates your targeted process first and kill it.

Which means there are likely two running in tandem. If you have the path/name of the files in question, you could try adding them to HKLM\SYSTEM\CurrentControlSet\Control\Session Manager\PendingFileRenameOperations and reboot the machine.

How to find weather the thread is still alive when using hThread = (HANDLE)_beginthread()

Start windows in safe mode. Run various tools to see if they can uninstall the offender. If not, track down the offending app and the one that starts in and delete them. (If you know the name of the EXE, that can help in searching for a cleaner.)

Also look in both the services module in administrative tools, but also the registry for a service that is likely restarting this (the google updater program does this.)

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

How to find weather the thread is alive when using

somthing like..
hThread = (HANDLE)_beginthread()

while (hThread==Alive)
{
// do some thing
}

chandu00417-Jun-09 20:33

Re: How to find weather the thread is still alive when using hThread = (HANDLE)_beginthread()

17-Jun-09 20:33

may not be an exact answer, but you can try this
make a flag 1 at the begining of the thread and make it 0 while returning.
use this in your primary thread.
while(flag==1)
{
//do some thing
}

Re: How to find weather the thread is still alive when using hThread = (HANDLE)_beginthread()

17-Jun-09 20:48

That may not work for me because I use BASE_ASSERT in thread fucntion
is there any work around

hThread = (HANDLE)_beginthread(ThFunction)
bDone=FALSE;

while (bDone != TRUE)
{
// do some thing
}

unsigned __stdcall ThFunction (void* param) 
{

..........
..........

BASE_ASSERT(SomeFunction); // here is the prome whe SomeFunctino fails

bDone = TRUE;
return 1;
}

could you find out what happens to the thread handle value when the thread is not running?
also explore getexitcodethread api in msdn

Hello Electron,

You can use GetExitCodeThread()[^]. If the function returns STILL_ACTIVE, then your thread is alive.

Re: How to find weather the thread is still alive when using hThread = (HANDLE)_beginthreadex()

17-Jun-09 21:06

But Can I use GetExitCodeThread() with out using AfxBeginThread(), becasue in this case I am using _beginthreadex()..
Is that safe ?

Jijo.Raj17-Jun-09 21:44

17-Jun-09 21:44

Hi Electron,

Sure you can. GetExitCodeThread() just needs thread handle and _beginthreadex() will return handle if it creates thread successfully. Have a look at the documentation from MSDN.

If successful, each of these functions returns a handle to the newly created thread.

Regards,
Jijo.
