VxDs only for kernel-mode drivers.
That means, if you don't need any functions only accessable from kernel-mode (e.g. direct device access), then you don't need a VxD.
Don't try it, just do it!

Hi all:
What "0L" stands for, "L" is the data type "Long" right?
But in the statement above, is "L" a operator or something else?
Thanks
|

The "L" is simply part of the C/C++ language syntax for identifying "long" integer constants. In Visual C++, this isn't used as much as it was at one time. Currently, the int and long variable types are both 32-bit signed integers.
In 16-bit environments, int values were typically 16 bits, and you have to use long to get a 32-bit value. This was the case in Windows 3.1 and MS-DOS programming.

i don't agree entierly
char is 8 bits long
short is 16 bits long
long is 32 bits long
BUT int depends on the system. 16 bits for example on Windows 3.1, 32 n WinNT, Win2K and current WinXP, but in few weeks, XP 64 will be available. int will so be 64 bits long !!!!!!!

On Win32, long is 32 bits, not 64. Even on Win64, long is still a 32 bit integer.

You'll notice I qualified my statement by saying "Currently, the int and long variable types are both 32-bit signed integers". This statement is true for C++ compilers used in the Windows environment (any other environment doesn't apply; this is a Windows programming site, after all). I didn't think it necessary to be pedantic about it, given the elementary nature of the original question.

Hi,
I have two radio buttons. onselecting one of the choices i want another text box to get enabled or become visible.

To Enable/Disable, use either :
EnableWindow(TRUE);
EnableWindow(FALSE);
To Show/Hide, use either :
ShowWindow(SW_SHOW);
ShowWindow(SW_HIDE);

Hi all,
Is there anyway to prevent losing data when trying to convert the float into long?
e.g:
float M=floor(13.22);//M=13
long N=long(M);//N=12????
Thanks.

By definition, you are going to lose data when going from float to long. What might be happening is that M=12.9999999 and thus returns 12 when doing the type conversion. Try this "long N = long (N + .5);". This is technically a round, but will avoid the whole problem with floating point numbers being inexact.

HI
How can i use the values in one dilog box in another dilog box.
Can we pass values from one dialog box to another?
Thanks
U get wht u Give
|
|
|

|

basically, you have to pass the value to the new dialog's constructor...
so, you have to overload the constructor of your dialog's class, which contains as parameters the values to pass to it...
to recover the values after the dialog treated them, you could either read the members into the dialog object (still existing when dialog has closed) if the members are public, or you pass to the costructor some references.

make a general class..... letz say CInfoz class,which has got all the information u need to pass to the second dialog.....
make an instance of the CInfoz class in both the dialog classes.....
then pass this infoz object whenever u open the new dialog .....eg:
say from one dialog class we call the second dialog...
dialog one
{
...
...
..
dlg = new CCreamzDlg;
dlg->infoz=infoz;//update the information
...
...
...
}
i hope u find thiz helpful!!!!!
cheerz.....

Hi all:
The DC is available, but how can i get what the color of brush is in it, and also some other parameters in it, such as pen etc.?
GetObject()?

Hello Kwib,
if you are using MFC,here is answer
GetCurrentBrush - Returns a pointer to the currently selected CBrush object.
GetCurrentFont- Returns a pointer to the currently selected CFont object.
GetCurrentPalette- Returns a pointer to the currently selected CPalette object.
GetCurrentPen-Returns a pointer to the currently selected CPen object.

Greetings,
I am trying to change the size of a FormView application after I have resized a control and I must be missing something essential.
I can get the window to resize (smaller), but then scroll bars appear that weren't there before. I suspect it is something inherent to how a FormView works as when I resize smaller manually, the scroll bars appear even though no controls are obscured.
I suspect I have some setting in the FormView wrong since it doesn't behave with manual resizing.
Anyway...
My current approach is to call AfxGetMainWnd()->GetWindowPos(), adjust the values and then call SetWindowPos(). Then I call ResizeParentToFit() which almost does the job.
Here is a code fragment. The control involved is a CListCtrl...
WINDOWPLACEMENT wpMain, wpOldList;
AfxGetMainWnd()->GetWindowPlacement(&wpMain);
m_RecordList.GetWindowPlacement(&wpOldList);
... make the size and content changes to the list ...
WINDOWPLACEMENT wpNewList;
m_RecordList.GetWindowPlacement(&wpNewList);
int sizeChange = wpOldList.rcNormalPosition.right - wpNewList.rcNormalPosition.right;
wpMain.rcNormalPosition.right -= sizeChange;
AfxGetMainWnd()->SetWindowPlacement(&wpMain);
ResizeParentToFit();
Any hints would be greatly appreciated. Thanks!

I'm not sure to understand, so I hope I won't provide a bad answer.
As I understand it, you want to force the size of your application. I would do so by resizing the MainFrame object, using CMainFrame::SetWindowPos. Then I would catch the WM_SIZE message in the Form View to handle controls size and position changes.
Oh, and you can manage the way your view handles scroll bars by overring CScrollView::SetScrollSizes.
HTH,
