Look at the following functions:
GetVersion()<br />
GetVersionEx()<br />
VerifyVersionInfo()

Covered the main ones
I had to do a similar class awhile back,
the function GetSystemMetrics(int); has two values which are useful
SM_MEDIACENTER and SM_TABLETPC
if you want anymore info about the system such as model
IWbemClassObject
good old WMI has a lot to offer.
p.s if your going to use GetVersionEx();
make sure your application fails safe if the wrong (unexpected) number returns
i know vista is new but wont be new forever

In life it's very important the things to fail safe, if so.

Hi
i have a class that makes a custom window,and at the WNDCLASS structure at
<br />
wc.lpfnWndProc=(WNDPROC)&CustomWindow::WndProc;<br />
i get the error:
<br />
error C2440: 'type cast' : cannot convert from 'LRESULT (__stdcall CustomWindow::*) (HWND,UINT,WPARAM,LPARAM)' to 'WNDPROC' There is no context in which this conversion is possible<br />
worked before in non class app as
<br />
wc.lpfnWndProc=WndProc;<br />
if someone could point out the problem or share a solution, it would be very apriciated.

To use a member function (method) as a callback like this, the method needs to be declared static.
That's because the OS knows nothing of your C++ object so it can't pass the implicit "this"
pointer that gets passed to non-static class methods.

Hello,
I have problem and I am wandering if someone can help me with a solution. I have a windows service that works well and when it is stopped by the user the server should disable the proxy settings. There are 2 great samples on codeproject that are working well on changing the proxy settings for IE. So I have moved a method named DisableConnectionProxy which works in sample code but does not work in the service. So I know for sure that DisableConnectionProxy method disables the proxy settings in IE, the same code does not work (it is executed but does not change the proxy settings) when it is part of the service.
case SERVICE_CONTROL_STOP:<br />
DisableConnectionProxy("DefaultConnectionSettings")
I think that this might have something to do with the service interaction with the desktop. The service is running under the Local System Account.
If anyone has a suggestion or can recommend me a good article I would appreciate it.
Thanks.

Hello everyone,
I read OLE DB section from MSDN and it is mentioned that to implement an OLE DB provider is very simple and easy (is it true?). But from the minimal support function list, I find there are a lot of minimal functions. Not that easy!
I am wondering where can I find some tutorials (documents) about how to implement an OLE DB provider in C/C++?
thanks in advance,
George

how to read only last line of file.
|
|
|
|
|
Technique 1: read the file line by line. When you hit EOF, the last line you read will be the last line in the file.
Technique 2: read the file in big blocks. When you hit eof, start at the end of the last block read, and search backwards for the line-ending sequence. That will be the start of the last line of the file.
And please don't use plz. If you don't take time to write your questions in good English, don't expect people to take time to help you.
Best wishes,
Hans

you can also use lseek to move the file pointer to, say, 100 bytes before the end of the file, read the whole 100 bytes block and discard all the bytes preeceding the last file line.
BTW I agree completely with Hans Dietrich: make a little effort to write in better English.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi
Can you please tell me how the default font of command buttons like NEXT,BACK,FINISH and CANCEL can be changed?

Consider using CWnd:::SetFont, for buttons of your interest. You can use GetDlgItem to access those buttons.
