You have to handle all these thngs yourself.Read each record from database and put them one by one into list control.
There is another list box in VC6 that you can add to your project it is good for your purpose.You can add it from the place you add other activex.

Hi there, what is a good way to run a worker thread as following:
- perform an action every 50-100 ms (variable to configure)
- meanwhile use less CPU power?
- accuracy of the configured time has to be +=100ms (that's fine but not longer!)
TRACE("me worker thread, me good\n");
for(;!bStopThread; )
{
Sleep(0);
}
TRACE("worker thread leaving\n");
|
|
|
|
|
ohhh, a simple Sleep(timeperiod_in_ms) does work! MSDN says Sleep() will suspend the thread. Wow, easy.
Which granularity can I use with Sleep(), which minimum value?
|
|
|
|
|
The argument for Sleep is in milliseconds

Is there a way that my program can fire an event when ANY application is opened/started.. for example my program customizes other windows, I want to know when these apps are started up so I can restore the customized options (so the user doesn't have to go back and reset all the customized options). Any ideas where I can start?
Thanks,
Rob Jones

You can use a global hook. Do a search here, there are a few articles on the subject. Here's a link to get you started...

How do I compare times using CTime. When I retreive a CTime value from the registry and compare it to the current time (using CTime::GetCurrentTime(), it also compares the dates which are several days apart. I need to compare the time part. Is there a way to mask out the date part then check if the current time is > or < the time saved in the registry?

you could create two new CTime objects like this:
CTime t1(1900,1,1,inTime1.GetHour(), inTime1.GetMin(), inTime1.GetSecond());
CTime t2(1900,1,1,inTime2.GetHour(), inTime2.GetMin(), inTime2.GetSecond());
then compare t1 and t2.
(there might be a better way, tho)

This is very simple. I'll use this for now unless I find a more common way. Thanks for you help Chris.

I've been using CSystemTray by Chris Maunder and it's really a wonderful class and made tray icon related programming very convenient.
However I found one problem, the icon shown on system tray is 16*16, so if the source icon is 32*32 it will be shrunk to 16*16, which obviously produces shape distortion. I thoughy that's not the problem because I could add a 16*16 format into the source icon so that it now has both 32*32 and 16*16 formats, but after I added new format it still uses the 32*32 format and shrinks the icon, it just seems to ignore any format in an icon but 32*32.
Now in order to let it recognize 16*16 format, I must delete(!) the 32*32 format from the source icon, by the way Visual studio 6 resource editor does not provide this feature, I had to use a third part icon editor to delete the format, now the only format remains in the icon is 16*16, and it finally worked.
Is there a way to tell the CSystemTray class to specifically choose a format from a given icon? Usually we will store both format in icon IDR_MAINFRAME, use the 32*32 for application main icon, and 16*16 for system tray displaying, that makes sense. We should not have to use two separate icons.
|

Visual Studio 6 can delete a specific "device bitmap" from an icon. Go to resource editor, open your icon and check the menu for something that looks like "Delete device bitmap" (sorry I use the german version dunno what it's named in the US version).
Hope it helps, I use the class and it works for me.
|
|
|
|
|
Great, I found the "delete device bitmap" menu, thanks.
My main problem still remains though, how do you specify an icon format? For example, you have an icon resource IDR_MAINFRAME, which consists of both 32*32 and 16*16 device formats, now how do you tell CSystemTray to "Hey, please display the 16*16 one on system tray!", can you?

When you load the icon, use LoadImage() and specify the size you want. This will work nicely for icon sizes, but be aware: prior to WinXP, the tray does not display icons with more than 16 colors, even if that's what you explicitly load.

AFAIK LoadIcon() can't, but LoadImage() can.
Well, I personaly never specify icon size, usually Windows picks the appropriate icon automatically. Hm if you feel problems try to trick a little bit:
SetIcon(AfxGetApp()->LoadIcon(IDR_ICON_DEFAULT), TRUE);
SetIcon(NULL, FALSE);
Do NOT call SetIcon() for the small icon with an icon handle if your big icon provides the small device bitmap too.
Another workaround: feed CSystemTray with an 32x32 icon which is a scaled 16x16 icon (each pixel is build by 4 identical pixel).
Hope it helps.

I have read the article by Chris Maunder about printing. But I'm having some problems. I would like to print plain text from a large CString. How do I know where to break the page??? I've read some articles about this but everyone is avoiding this bit.
Can someone please help a beginner ??
Regards
Henrik

because that's the hard bit.
you essentially have to measure the page, then measure the string. if the string is too long, break it somewhere (by breaking and measuring in a loop, usually). then print the first part, page break, print the next part (or, as much of it that fits on the page) and so on.
i'm sure someone will correct me if i'm wrong... but that's the way i've always seen it done.

CDC::StartPage and CDC::EndPage control where a page starts and ends. CDC::StartDoc and CDC::EndDoc control the overall document.

i want to call the main window of my sdi from a custom dialoge .. is there any way for doing it..
secondly i want to make a check such that every time when i run my software it could check the values in the database .if the data base is all empty it should call the secondary dlg first with displaying the main dlg. and if the data base has some entries then the main dlg should be called.
thanks for ure help
looking forward from all the gurus of code

This is not what you're asking for, but maybe you can solve your problem by calling the secondary dialog directly when needed in your app's InitInstance, right before the main window initialization.

I've developed an ATL service which offers an interface.
I observed the number of threads the service handles is as big as the number of CoCreateInstance/Release calls for a pointer of that interface.
It seems like the number of threads is only increasing and never decreasing. Is this true or there is a timeout for any thread?
Is it possible to have bugs in my application, despite of the fact that i didn't create any thread?

I have some code in a button event. When i push the button an unhandled exception appears saying "Stack overflow". If i put a breakpoint in the first sentence in the button event the Stack overflow message appears anyway so it hasn't executed any code when i comes with the Stack overflow message. If i remove all the code from the button event nothing happens... what's wrong?
