window is event-base, that means that when the application catch a message, the "main function" (winmain) calls the function associated to this event. if you write a while loop in one of these functions, you take the risk that if your loop is infinite, your program look dead (in fact, blocked in the loop)... you so must be careful on such loops in windows programming.
why do you want a while ?
can't you use a timer instead ?

Huh ?
what exacly are you trying to do ?
while loops work the same way in dialog based applications or console applications; loops will always "stop" the normal flow of the application; meaning that if you want to use a while loop in your dialog, and you see that the UI does not respond, well, that's the way it is; if you need the UI to respond to user input while doing a loop, have a look at some of the articles here on CP ( I don't have a direct link ).

When using scrollview how often does the scroll refresh the screen?
Right now my text print out would overlap if I scroll too fast. As soon I resize the print out would be correct, which leads me to believe scroll is skipping drawing update.
I wrote a little debug to see what my scroll position but most of the time it wouldn't print out until I resize the window.

|
|
|
|
My debug info should disappear when I scroll but it stays around when I scroll up and down(until "next scroll update" or resize update)

Hey every one.
we know that we can change any project and give it xp look, but I am wondering if there any way to give it MACINTOSH look...
I read in the site -=> http://www.codeproject.com/w2k/xptheme.asp[^]
by using xml codes... so any way to do it but with MAC theme?
thanks in advance

Not as simply as it is for the XP theme - that example is to make a non-.NET app running on XP use the XP theme - it's not overriding anything in the system, just setting a few flags to tell Windows how to handle the application.
If you want to use an entirely different theme, then you'll either have to code it yourself (creating derived classes of all the standard controls and custom painting them - not an easy task at all!) or use something like WindowBlinds[^] that can re-skin Windows to look vastly different

I am having problems adding the current date and time to a string. This is the code I have so far. Please let me know what I am doing wrong.
CPString psPathFile;
SYSTEMTIME systime;
GetSystemTime(&systime);
psPathFile += "C:\\It\\";
psPathFile += "data";
psPathFile += systime.wYear;
psPathFile += systime.wMonth;
psPathFile += systime.wDay;
psPathFile += systime.wHour;
psPathFile += systime.wMinute;
psPathFile += systime.wSecond;
psPathFile += ".mwd";
Thanks,
Einar

The problem is that systime.wYear, wMonth, etc are not strings or characters - they are decimal values of the year, month, day, etc.
You need to format those values to strings. (I'm not familiar with CPString as you have, but for CString you could use something like:
CString psPathFile;<br />
psPathFile.Format("C:\\It\\data%4d%2d%2d%2d%2d%2d.mwd", systime.wYear, systime.wMonth, systime.wDay, systime.wHour, systime.wMinute, system.wSecond);
The end result would look like:
C:\It\data20041129132020.mwd
Hope that helps.

That seems to be exactly what I need, but I noticed something odd.
This is one result I received:
c:\it\data20041129205020.mwd
This result would be fine if it was 8:50PM but it is 2:50PM here now. Should the result be using military time (24 hour clock)? And why do I get 20:50 when it should be 14:50?
I also received an odd result when seconds where lessw than 10:
c:\it\data200411292050 7.mwd
Is there any way to get it to left pad it with zerso?
Thanks,
Einar

|

Well the left padding with a zero was pretty easy just use the flag 0.
The issue with the hour is still puzzling me. It is just past 3PM (15) on my computer now but somehow the SYSTETIME.wHour thinks it is 9PM (21)
Any help would be appreciated.
Thanks,
Einar

Hmmmm I guess the only thing that makes sense it that I am located in the central timezone (GMT -06:00) and what do you know 21:14 - 06:00 = 15:14 which is the time my computer tells me it is.
Wow this is really odd and I would rather the computer gave me the current time (according to the computer) and not changing it to GMT.
Anyone know how to accomplish this?
Thanks,
Einar

According to MSDN:
GetSystemTime<br />
The GetSystemTime function retrieves the current system date and time. The system time is expressed in Coordinated Universal Time (UTC).
You might try
GetLocalTime<br />
The GetLocalTime function retrieves the current local date and time.
Hope that helps.

GetLocalTime was just what I needed.
Thank you much.
Sincerely,

How can I calculate exactly the size of a string in Bold or Italic? GetTextExtent() apparently doesn't care about Bold and Italic settings.
Thanks.

Dear Sirs,
We need to create an application that supports Hebrew. Could anyone please give me an explanation on how use hebrew strings as resources and use them on a Visual C++ 6/MFC application? 
Thanks,

Hi I'm still newbie in VC++ and MFC. I'm writing an application, and need to create controls at runtime. For example, I need to create a button on a window every time I click on another previously created button.
I think that the biggest difficulty is mapping messages from those controls.. I have a CButton list to store the buttons, but how to tell the parent window to process every button messages??
Thanks for your time!

Determine which NIC is the one that is providing me with 'default' internet access?
For example, you open IE and go to google. Which NIC is it using? Currently i use gethostbyname() which does list all the IPs the machine has, but I can't figure out a way to tell which one is the active one.

What is the advantage of using VERIFY in the Release version . IT gets evaulated but doesnt terminate in case of the expression evaulates to FALSE .
|
|
|
|
|
The advantage is exactly that it *does* get evaluated. As you may know ASSERT does not.

If it doesnt not interrupt the Program why do you need it ?

You still want the code to execute and do something usefull in the Release version.
e.g VERIFY(CloseHandle(hHandle));
In DEBUG will assert if it fails to close the handle. In RELEASE you still want it to attempt to close the handle.
You could write it:
BOOL bOK = CloseHandle(hHandle));
ASSERT(bOK);

The simple answer is that when developers put a statement into an ASSERT while they are building code in debug versions, that statement can either be something that is used just to check a result or something that should execute AND check the result. Since many developers have a style of putting "real" code in their ASSERT statements, they found out that in the release build, those statements disappeared, as the ASSERT statements were ignored.
Thus the utility of VERIFY. If you use an ASSERT and only use a statement that tests a condition, then you are alright in both debug and release versions. If you put "real" code into an ASSERT and expect it to always execute in both debug and release versions, then you should use VERIFY instead.
