Be aware that on NT, if you modify the MBR or any boot sector, the OS will come along a few seconds later and restore the sector from a backup copy that it keeps. You have to lock the volume before writing to the sector (however I don't know off-hand how to do this).

Hi (for the second time today),
I'm getting the following error and im not sure why -
d:\projects\common\winctrls.cpp(145) : fatal error C1010: unexpected end of file while looking for precompiled header directive
When you double click the error (in VC6) it takes me to the end of "WinCtrls.cpp", which is the implementations of all of the class functions defined in "WinCtrls.h". Now I dont know much about the compilation process, but the only "non code" bits I have are a #IFNDEF, a #DEFINE, and a #ENDIF. Does anyone know what may be wrong. I'll try and explain further if needed.
Many thanks again
Zak

did you forget to add #include <stdafx.h> as the FIRST include statement in your .cpp file ?
have you forgotten something in a .h file somewhere ?
maybe an #endif or a closing brace } or a ;

In addition to the other reply you got you should also check to ensure that any third-party installed headers in 'some' directory are listed in your include paths in the Project Settings tool.
In the C++ tab under 'include directories' Add the *.h/hpp file to your 'include directories' settings:
ie: C:\thirdpartysdk\inc
In the Link tab under the 'Input' category, add the name that contains the library (*.lib file) to the class you're implementing.
As above, enter the path to the directory containing the lib file in the 'Additional Library Path.'
I know this is more than you need at this moment but I think it will help out in the future.

speaking of which, didn't the faq appeared on the top of the window ? I had to search for it yesterday

I asked Chris about it yesterday. He said he's redoing some parts of the site layout, and the FAQ link will come back soon (but it will only be visible when you're in the C++ forum).

Kindly help me how to figure out why this is not working.
Thanks.

Hi,
I want to make a dialog only based program without using MFC or anything. Problem is I need a parent HWND variable to send to the DialogBox() function. Im assuming I should pass the HWND of the desktop but Im not sure. If this is what I should be doing, how do I retrieve this, but if not, how should I go about this?
Thanks
Zak

You can either pass NULL, or a handle to the desktop window. You can retrieve this with GetDesktopWindow().
Hope this helps,

Harumph. I have 2 problems, one directly related to this function, the other is not.
First, i need to use SetDlgItemText() to display an integer in a static text thingy. At least, i assume this is what i should use. I can do it just fine displaying strings, but when i try to display an int, it says it can't convert int to LPCTSTR or something similar to that. Whats the best way to fix this? Should i use some sort of integer to string conversion?
Second, i need this integer to constantly update in my dialog. What i'm doing is reading a value from a volt meter, and for each reading i get, i want to display the new value. I tried putting my SetDlgItemText() in side an infinite for loop ( for(;;) ), but when i launch the dialog window, the program crashes. This is all opccuring in the dodataexcahnge.
Grr. its the simple problems that really tick me off. :P

1. SetDlgItemInt()
2. Using SetDlgItemInt() should solve this problem.

doh, new it was a simple one. thanks.
I still have my refreshing problem tho, any ideas?

Do you know what's causing the crash? You mentioned it was in DoDataExchange(). Post your DoDataExchange() function and tell us which line is crashing.

void ReadAnalog::DoDataExchange(CDataExchange* pDX)
{
CDialog::DoDataExchange(pDX);
int value;
value = 1;
for(;;)
{
SetDlgItemInt( IDC_READ_ANALOG_01, value );
}
}
at some point i will add code to read in from a meter and store a number into 'value' but until then, i just set it = 1.
I don't exactly get an error when i open the dialog window, however, the window does not open and i get the (Not Responding) thing in the title bar of my program. My assumption is that this for loop executes forever, and the page will not get created until it is finished. (I just made the loop go from 0-20, and the program worked fine.)
Is there some other place i can update the value of the static text after it has been displayed?

That's correct. An application is considered to be responding if it checks its message queue. You are not checking the message queue, and therefore cannot do anything (including updating the screen), and therefore the program is not responding.
The method I would use is to set a timer (for 10ms or something like that), and update the value whenever the timer message handler gets called.

ok, suppose i use Sleep(10) to wait 10 miliseconds, then display the data. This provides a problem, being that it still only updates once. You said to update whenever the timer message gets called, well, if i put this in my ddx, it will only get called once, when the page is created, correct? Is there someplace else i can add the data, after the page has been created?
I guess is what i'm asking is how do i put a an infinite for loop in a dialog box.

I hope not. That's a bad bad idea 
What I meant was to use SetTimer() to start a timer that posts a WM_TIMER message to your message queue every 10ms or so. You then handle the WM_TIMER message, and whenever the message is received, update your dialog - don't use an infinite loop. In your WM_TIMER handler (OnTimer()), call SetDlgItemInt() to set the new value. It's not necessary to use DoDataExchange() at all.

Does anyone use the undocumented PushMessage Commnad anymore? This was my solution to this problem. I geuss it is undocumented for a reason in that if you use it improproperily it can cause strange slow down and crashes, but it seems more elegent to me.

 I've never seen that function. And if I had, I probably wouldn't use it because it's undocumented, which basically means it could change or be removed at any time . I generally stick to the documented functions if possible.

Answer to first question.
You need to convert your int to a string;
INT MyInt = 5;
CString MyString;
MyString.Format("%d", MyInt);
SetDlgItemText(STATIC_ID, MyString);

All is in the subject !

Any clues ?
