Then you are obviously going to have to requery the database each time. That is the only way to get updated records.

Hi,
one stupid question:
I need to know the handle of the main dialog created by the MFC Wizzard (dialog based app). How to get that? I am confused that I couldnt find anything about it. I am using this for a class for minimizing the app to the tray.
Do this dialogs have a handle?

CWnd::m_hWnd
CDialog is derived from CWnd, so you can access m_hwnd from CDialog or through CDialog !

Thank you!
Thats it!
Btw, why cant I see this member variable in the ClassWizzard? I just see my own vars...

I think if you saw every inherited function and variable from all the parent classes, classwizard would be almost useless. 
If I write code in my sleep, does that make me brilliant, or just a lazy programmer?

You use Shell_NotifyIcon() for this. There are plenty of examples on how to do this here at CP, and on MSDN. You can Google for even more.

Yeah sure. I did that, and got it to work. I am having other problems with the trayicon, which caused the problem! I have an MFC app, where I wanna handle Messages, eg. a Buttonclick on the icon. I dunno how to do that. Who can tell me just the base. I can learn myself, but I need to know the base. For a normal app you make an endless loop checking for messages. But here?

 ok....tis a long story.....here goes......
u c.....the code.....
HICON hIcon = AfxGetApp()->LoadCursor( IDC_CURSOR1 );
SetCursor( hIcon );
return TRUE;
is a working code coz i have put this in my Dialog based application (Xyz) in a class called CXyzDlg..... that is, i have already added this function "OnSetCursor()".....and the cursor changes......in the main Dlg box but..... i have derived a class from the CStatic Class named it as "CMyClass".....and i have created obcts of it in the CXyzDlg class.....basically these objects i have created by placing the "static control" on the dialog box and then..... thru the class wizard created an object linking it with the picture control of type CMyClass(that is .....SUBCLASSING).....
also in thiz CMyClass i have added the "OnSetCursor()" function as well......and many other mouse functions like "onmousemove()","LbuttonDown()".....etc.....but here when i put in the same code as i had put in the main Dlg box for the "OnsetCursor()".....it does not change!!!!!......y???
heres the code......that i have put in the derived class CMyClass......

How can I convert an _int64 variable to double?
|
|
|
|
|
How about:
__int64 i64;
double d = (__int64) i64; If you are using the .NET framework, check out the Convert.ToDouble() method.
Another way would be like:
__int64 i64;
char s[32];
sprintf(s, "%I64d", i64);
double d = atof(s); I've not explicitly tried either of these.

A fixed font should allow 80 columns across a screen. However this doesn't quite fit when there are standard borders around the window when viewed in maximized mode.
Can anyone suggest how I can display a window, based on CScrollView, which does not have the normal side borders. Either no border or a very narrow border.
All suggestions appreciated.

Hi,
I want to write an application.
I want to hide it in Task List on Windows 9x/Me.
Please help me !
Thanks.

Does ShowWindow(..., SW_HIDE) not do what you want?

I use ShowWindow(..., SW_HIDE).
It will be hidden. But It will be shown in Task List.
I don't know the way to hide it in Task List.
|
|
|
|
|
I do not know of a way to hide processes (those items on the Processes tab) shown by Task Manager. Why do you need this functionality?

"Run in background" is a phrase not used with Windows since it is a multitasking OS.

This sounds very suspicious. Can you explain why this should not be considered a virus, worm, or trojan horse?

Have you seen EasyCafe, an application to manage PC room ? I want to write an application same it.
When I use Ctrl+Alt+Del to show Task Manager, I don't see it in Task Manager. So I cannot kill it.
|
|
|
|
|
As I understand it, to trap the Ctrl+Alt+Del keystroke combination requires the creation of a custom GINA DLL.
For Windows 9x and Windows Me, you can use SystemParametersInfo() to trick the system into thinking that a screen saver is running.

The solution trapping Ctrl+Alt+Del (using SystemParametersInfo) is not appropriate for my application. Because it will also trap Alt+Tab.
My application allows users :
- kill other applications (using Ctrl+Alt+Del)
- switch among applications (using Alt+Tab).
I'm finding the way to solve this.
