if the path is relative then current directory is cosidered as the working directory.
so if you just specify the file name like test.txt then test.txt should be in the same directory as the .exe file that you are invoking.
But invoking it from the visual c++ editor(i.e ! button) will not work as it sets the current working directory to something else (i dont know what, may be the project directory, one below debug)

One thing to remember is that the current directory is not the same as the program directory. This is a very common mistake made by programmers.
In your case, I don't think that will be an issue since it doesn't look like you are trying to open a file in the same directory as the program.
BTW, with VS7 (and maybe 6), the working directory is not the "debug" or "release" directory. It is the project directory.

Why would any one wants to diable the system time to be shown?

In industrial applications, you might want to prevent the user from goofing with the system.

Mr.Prakash thank you for you're response, but it would really be a help if you told me what is the usual way for disabeling the acces to System Clock...
it would help me verry much ...
please reply to this message.

The wndclass of the system clock is TrayClockWClass may be you could figure it out what to do with the window after using FindWindow on it.

well .. i have already done that...
i have found the window and disabled it, hidden it .. but double click still works...
So i need it because i have written a program that uses system clock..
and do not want other users to change it...
i don't mean programmers.. but the usual user who knows to double click the sysTray ...
so any other ideas?..

You need to subclass the window so that you can handle the doubleclick event and do what you want to do (ignore it).

Does Monitor need a "Root-Enumerated driver"?
Because when I ran sample Win2K installer as:
c:\install "775FT.inf" "Monitor\GSM42D1"
I got the following error:
UpdateDriverForPlugAndPlayDevices FAILURE: (0xe0000219)
We know:#define ERROR_NO_ASSOCIATED_SERVICE (APPLICATION_ERROR_MASK|ERROR_SEVERITY_ERROR|0x219)
(Monitor has not a services! Is it OK?)
How can I solve this problem!?
Notice: DDK2K install sample has a problem, So first see:
http://www.codeproject.com/script/comments/forums.asp?msg=801613&forumid=1647&mode=all&userid=67503#xx801613xx[^]

If you need to build an installer application for a specific monitor, why dont u use the Setup API functions and build yourself your installer? This way you will know whats going on in each step if the installer program is giving u trouble. I'm not sure if monitor drivers use services ... open up the inf file and look for a section like [xxx.ntx86.services] or [services]. even better: search for the string "AddService" without the quotes. That way you'll know if it uses services or not. Hope this was helpful.

I have an application with a window that has a edit box. I am writing a integer value to the box. The default font size is too small. I need to make the font size much larger in my application. I dont know how to use CFont to make the number larger before sending it to the edit box. Can someone help me out? Do I need to use CFont at all?

Well, you don't need to use CFont, but it's easier.
There are two ways:
a) fill a LOGFONT structure with all the informaiton required, then can CFont::CreateFontIndirect
b) Get the current font from the edit control, get it's properties by calling CFont::LogFont, change the height in the LOGFONT structure, and create a new font (again using CreateFontIndirect)
b) is probably better, and a little bit easier too...

hi all
i got the problem that my application's ExitInstance is not called. i traced and found that ::GetMessage in CWinThread::PumpMessage never returns FALSE. it seems that WM_QUIT is handled somewhere else, because my application exits normally via menu or by clicking on the main frame's close button.
any idea?
thanx

MSDN: Device Installation Functions
This section describes the Setup functions that support device installation on Windows 2000 and later versions of the NT-based operating system.
... Most of these functions are not supported on Windows 9x/Me.
I want to install a small driver that only have a single sys file like DDK PortIO sample.

Im using a Java dialog to call a C++ app using JNI, All I want to do is pass an object into the cpp app, there is no writing to be done in the class, just passing strings and bool values. How do I change my main() in cpp to be able to accept this object and be able to compile it into a .dll
Any articles or help is appreciated.
Cheers

I have written a program, in which, I declared a global variable such as:
<br />
typedef struct{<br />
char buff[20];<br />
} my_struct;<br />
my_struct my_arr[1000][30][10][10][3];<br />
In particular: the size of my_struct is 20 bytes.
My calculation showed that the size of my_arr variable is:
1000*30*10*10*3*20=180.000.000 bytes or close to 180M.
But when I run that program, Task Manager showed me the program took only 3MB (in Mem Usage column).
When I started to fill data into my_arr, Mem Usage increased very quickly and program terminated abnormally.
Does anyone explain me about that situation? I used VC6 and MFC.
Thanks for reading.

May be it was optimised by the compiler and may be windows too.
so as and when you started filling up the data memory was allocated to it..

may be you overshot the buffer.

By my_struct my_arr[1000][30][10][10][3]; you are allocating memory in the stack, and I don't think the OS will allow your application to allocate that much(180MB) stack memory, so definitely it was going to be terminated abnormally. What I don't understand is why it did not crash right away... Yeah, I too hope some gurus explain it.

How many are limitation of stack memory!?
And if we need huge memory in global, how can we do it?
