And how will be your messages processed ? 
You can put as much Sleep as you want, if you block the main thread, your UI will be frozen and no messages will be processed (so, your text won't be updated neither).
|

|
|
CString s="in progress";
m_wndStatusBar.SetPaneText(0,s);
Sleep(3000);
s="success";
m_wndStatusBar.SetPaneText(0,s);
This code will display first "InProgress" then after 3 seconds "sucess" will be displayed.

Yes you are right, I tested it.
Anyway, it still isn't good practice to do so: your UI will be totally frozen (with the button pressed) the time it takes for the processing. If it takes really a long time, then it is better to put that processing in a separate thread so the the UI is not affected.

i tried both sleep and thread methods...both doesn't work!!!!!!

How long do you Sleep ? And how much time is your operation taking ?
|
|
|
|
|
sleep is for 4000...and my operation is less than that..iam sure abt that...as print statements given before that prints the sring...but the status bar updates is not shown

Could you describe exactly what's happening and what you expect ?
The code that was given to you as example should print "in progress" in the status bar for 5 seconds (depends of the Sleep time) and then it will be replaced by "sucess".
What happens if you just take the code that was given to you and remove your call (just keep the SetPaneText calls and the Sleep) ?

i have done the following in my code...and i have my progress bar too in my status bar in the second pane....i need "inprogress" to be displayed first and then the " complete" text...but inprogress doesn't get displayed...what should be done
void test::OnLbnSelchangeList1()
{
void (*ptr)(void )=function;
thread_data td;
while(1)
{
if(Complete == 1)
{
indx=list.GetCurSel();
s="in progress";
m_bar.SetPaneText(0,s);
td.threadentry=(LPTHREAD_START_ROUTINE)ptr;
td.hdArg=NULL;
td.udiCreationFlags=0;
CreateThread(NULL, 0, td.threadentry, td.hdArg, (unsigned long) td.udiCreationFlags, (td.udiThreadId));
pPrgCtrl->SetPos(0);
while(1)
{
if(Complete==1)
{
pPrgCtrl->StepIt();
break;
}
}
break;
}
}
Sleep(200000);
pPrgCtrl->SetPos(100);
printf(" complete\n");
s=" complete";
m_bar.SetPaneText(0,s);
}

Sure you do. Check again.

What happens if you comment out the second SetPaneText() statement? Does "in progress" remain in the status bar?

sorry...if i comment the secondsettext the first one is getting displayed ie in progress is displayed

Could it be that the code in between the two calls to SetPaneText() is just happening too fast?

no,its a long process...it takes 3 to 4 mins
Raja

It sounds as though your long process is taking up all of the CPU such that the first SetPaneText() does not get a chance to paint (i.e., the WM_PAINT message has not been processed).

so ...what should be done to slove this problem???i need the gui updates to be shown along with the process

I would use a secondary (worker) thread to do the work. That way the primary thread can remain responsive and handle painting.

Hi Friends,
Can I do something like this ? Is it portable across all platforms ?
<br />
int* ptr = new int();<br />
int& tmp = *ptr;<br />
delete &tmp;<br />
|
|
|
|
|
I am not sure about portability issue but is there any specific reason to do this? These kind of smart-ass statements makes code harder to read and maintain.

My design of stuff is another issue.
Basic question here is
- is this a standard practice?
- Are there any issues?
|

It mostly depend if you are interested in generic programming and in having value vs pointer semantics.
until &*&x == &x whatever x, than what you did is true.
Of course if x overloads * and/or &, things may be not be as expected, but sometime this is wanted by certain generic algorithms.

delete &tmp;
Another hint for not to be in trouble - if you delete by using reference, then the ptr variable will become a dangling pointer.
