Hi,
At the beginning of my application, i declare a COleDateTime object like that:
COleDateTime Date1;
After, i have to compare other dates(Date2,Date3), and then change Date1, which is inialized firstly to 0, like that:Date1=Date2.GetDay()/Date2.GetMonth()/Date3.GetYear().
So, i don't know how i could modificate Date1 in this way, is anybody coule explain me how to do that?
thanks in advance.

You mean that you have a line like this in your program?
Date1 = Date2.GetDay()/Date2.GetMonth()/Date3.GetYear();

of course not, it's a representation of what kind of date format i want, for example, if date2=5/09/01 and date3=18/12/03 i want to do a sort of concatenation with the twice to have the result:5/09/03.
I hope you see now what i mean.

Just like James posted - use COleDateTime::SetDate:
d1.SetDate(d2.GetYear(), d3.GetMonth(), d3.GetDay());
Year comes from d2, and month and day from d3.

Use the member function SetDate().

Handling WM=CTLCOLOR you can set the back color of the control, use pDC->SetBkColor(COLORREF)

Hi
I drew a few line .Now I want to select a particular line by clicking on that line.I implemented a funtion which will take the mouse point and end points of line as parameters and returns true if the point is on the line by using Bresehalm's algorithm.for that I need to find the slope of line.the window has default mapping mode MM_TEXT.How can I convert the device coordinates into physical coordinates as if I place the mouse over the line the function should return true?how to solve this problem?please help me.for the lines with negative slopes I am getting errors.
Thanks

is ScreenToClient() what you are looking for?
Else search for "Coordinate Space and Transformation Functions" in MSDN...

How can I convert the device coordinates into physical coordinates
There's no such thing as 'physical coordinates' in GDI. You can convert between device and logical coordinates using LPtoDP and DPtoLP, but I don't think this is going to solve your problem.
Check http://www.faqs.org/faqs/graphics/algorithms-faq/, item 1.02 - "How do I find the distance from a point to a line?". If distance is small, you can assume than mouse is over the line. The definition of 'small' depends on your application - you can use some tolerance in testing, for example if user clicks two pixels from the line, it may be close enough.

Dear all,
I have a trouble in executing my AP in WinNT 4.0.
It shows a dialog saying unable to allocate entry
point __lc_collate_cp in MSVCRT.dll. I copy MSVCRT.dll
to the directory but still failed.
The AP runs ok under win98, win me and win 2000.
Can u help me about this??

Use the Dependency Walker (DEPENDS.EXE - it comes with VC++) program to analyze dependencies between .dlls used by your app. You'll have to copy depends.exe to NT4 machine.

I used the Dependency Walker and found that the default MSVCRT.dll are different in Win98 and WinNT4.0. The one in WinNT4.0 lacks the function __lc_collate_cp. It's why i get the error in WinNT.
I went to the MSDN web and found that the error may also occurred in Visio 2000. Microsoft recomment user to update MSVCRT.DLL by user himself....
I also found that my AP uses MSVCP60.DLL and this call to the __lc_collate_cp in MSVCRT.DLL. Could u tell me what kind of library will link this DLL ??

MSVCP60.DLL contains STL-related classes, like std::string or iostreams.
You basically have two options now:
1) link statically to C runtime
2) create an installer that updates MSVCRT.DLL and MSVCP60.DLL. Note that users will have to reboot after install - these .DLLs are used by Windows itself and can't be simply overwritten.
Oh, and there's one more possibility, but I've never tried this: you can copy correct MSVCRT.DLL and MSVCP60.DLL to your application directory. The Windows loader looks for DLL in app dir first.

It's right, I used STL in my project and it causes this problem.
I'll use static link in my project to solve this problem because it's not working by copying the 2 DLL in the AP's directory in NT...
Thank u...

Hello everyone,
I have an application that need to connect to a mapped drive using the CreateFile() function. It ran fine as an application. However when i convert the application to a NT Service, it can't work.
What is the cause for this and how do i solve it?
Any help would be great
Thanks

What account is the service running as? Mapped drives are specific to one account, so if the service is running as the system account, it doesn't have the drive mappings that you make in your own account. Change the service to run under your account.

By default all services logs on as the "system" user. This user is different for every NT machine on a network. That's why it only have access to the local machine.
If you want a service to connect to other machines, you should make an account on those machines with the same username and password, or if the machines are in a domain, just make a domain account. When you change the service to log on as that account it should work just fine  (if this user have access the the shared resources, of course)

Oops, I forgot...
You cannot connect to a mapped drive like "m:" you have to connect to the UNC path like "\\server\share".
I don't know how you map's your drives, but most often it happens with a logonscript, and a service can run without you are logged on. Even if you are logged on it won't work for the service, because it actually runs under another (hidden) desktop than you do...

Hello all,
I have created a dialog type app.. I have a modeless dlg box that needs to run a timer, the reason it's Modeless is the timer needs to be active all the time even when the Dialog box it hidden (I'm checking if the timer is equal to a int every second, when they match I run a event).. I added the WM_TIMER function to this Modeless dialog.. When I fire the "OnTimer(UINT nIDEvent)" by doing a "SetTimer(IDC_S_TIMER1,1000,NULL);" from another control, I get the following error in debug mode:
First-chance exception in Dialog.exe: 0xC00000FD: Stack Overflow.
And it points to OnTimer(UINT nIDEvent)
->{
Any ideas why?
Thanks,
RobJones

The stack overflow could be caused by recursive calling OnTimer(UINT nIDEvent). How does the call stack look after the exception?
Cheers
Steen.
