This makes no sense. Go back and read this thread again, and then reply with a bit more coherency.

hi
i have a newbie question
how to pause execution of a code block
without sleep effect
for example :
void somefunc()<br />
{<br />
SetWindowText(hWnd,"hello");<br />
WaitFor(5000); <br />
SetWindowText(hWnd,"good bye");<br />
}
when WaitFor() called, application must continue
execution other functions and application must response to other function calls
finally i don't want to  sleep complete application when waiting
thans

Use a timer for that. This will be different than your code snippet because the two calls to SetWindowText will be located in two different parts: the second one will be in response of a timer event.
You can't "wait" in a function a still continue to process messages from the UI (which is in the same thread), unless you pump the message loop, but it is quite ugly in your situation.

thanks for your quick reply
but it is a Dll how can i use a timer in a dll
is there any idea for that
when i call , a wait function from dll
i want to call another function from dll at a time
but first call freezes main application already
and dll is not responding
thanks

You can also use a multimedia timer. The timer callback will occur on
a different thread so you don't have to worry about your UI going dead
or pumping messages.

One technique that sometimes works is simply pumping the message que while waiting.
void YourClass::somefunc()
{
SetWindowText(hWnd,"hello");
SleepWithEvents(5000);
SetWindowText(hWnd,"good bye");
}
VOID YourClass::SleepWithEvents(int Millisecs)
{
ULONG Ticks = GetTickCount();
while(GetTickCount() < Ticks + Millisecs)
DoEvents();
}
VOID YourClass::DoEvents()
{
MSG oMSG;
while(::PeekMessage(&oMSG, NULL, 0, 0, PM_NOREMOVE))
{
if(::GetMessage(&oMSG, NULL, 0, 0))
{
::TranslateMessage(&oMSG);
::DispatchMessage(&oMSG);
}
else
{
break;
}
}
}
Best Wishes,

i have a modeless dialog box. and in my first dialog box i have some values. the same values needs to be shown in the modeless dialog box also. i am getting an exception. not being able o figure out what it is.
i have created a member variable for the class and i can also access the members of the class. but i am not being able to pass the value.
in the second dialog box i have an edit control which is of type CString.

Did you try to debug your program to pinpoint where the problem occurs exactly ? Use the callstack to locate the problem in your code when the crash occurs.
Without having more information, we can't really help you. We need some relevant piece of code (don't paste the complete source files  ). If you can't fix the problem using your debugger, provide also the info you gathered with it.

i had added DoModal() which i should not have done.. now i am not getting that exception. but the value is not being updated on dialog2. but when i debug in the watch list the value is updating.

Please read my previous answer and provide the required information. I'm still not able to read what's written on your screen (although I'm trying hard, it's probably because of the distance...)

are you calling updatedata() to reflect the changes on dialog box.
|
|

|

When you are opening modeless dialog?
You add same type of variable to modeless dialog class, before creating it assign first dialog value to modeless dialog variable, after creating it, show the value.

Hi Edit controls are of type CEdit. Did you mean you have control variable for edit control?
Thanks,

Hi,
I am using the MFC doc/view framework to do the printing in my application but it isnt clear what I need to do to print multiple copies (as entered by the user in the print dialog). I can retrieve the number of copies but where do I use it? I figured that Windows print manager or the framework would do all the work involved but it doesnt seem to work so maybe I need to do something.
Any ideas?
Tony

I'm a little surprised that the basic MFC framework doesn't handle that for you.
But printing is harder than it looks! MFC glosses over some details, but the moment you deviate a little, you're on your own.
I strongly recommend Roger Allen[^]'s articles for reading. Many of them are involving printing, and all are good.
I vaguely remember him buying me a pint once...
Iain.
