Sorry for the question may be stupied but I am in dead end.
How can I sumulate ctrl+alt+del from my service or application.
For example: All desktop administrators has this function. I want to implement it in my application.
These days I search all the net for sample could not find exact. Find some using
keybd_event, SendInput but I could not simulate what I want......
Thanks in advice

You can't just "send" a CTRL-ALT-DEL to the system.
Search MSDN (or Google for that matter) for GINA.DLL and SAS.
GINA: Graphical Identification and Authentication
SAS: Secure Attention Sequence (a.k.a. CTRL-ALT-DEL)
I myself haven't written my own GINA dll but this will point you in the right direction.

I don't know the reasoning for simulating the CTRL+ALT+DEL sequence, but there's a function LockWorkstation, that does something similar (but also locks the station, so it's more like CTRL+ALT+DEL followed by ENTER)

The Ctrl+Alt+Del sequence is not very useful by itself. It's what action you take afterwards that is important. What exactly is it that you are trying to accomplish?

Thanks all for the answers !
The point is that I want to make my service to simulate login to Windows 2000 server.
To execute one program(not written by me) as administrator and to lock then the server using "LockWorkstation".
I do not want to use Automatic Windows Login for some reason.
I know that there is another way to make my service to Login as administrator. To make it interact with server and to LoadProfile to set desktop and to execute the program. I search all MSDN and internet and find some samples and make all this, but for some reason it fails. I dont know why. It is dialog based and do not start. A program written by me which is dialog based also is executing fine and without any problem. But this do not why. So I look for another way to do this.
And the way that I think is good is this that I described.
So I will try to find sample about GINA and SAS and will write the result.....
If you have any suggestions I will apriciate them .

Is there a configuration file under WindowsXP, etc., that lets you set up the maximum number of files you may want to open with fopen()? I know there is a way to set this with a call to a function in <stdio>, _setmaxstdio()...but I thought it could be done another way.
Thanks.

What limit are you currently running into? Is the same limit imposed on you when using CreateFile() instead?

Hi everyone
Does anyone know how to resize a user selected image with new user choosen length and height? I know that there is bitblt but I dont know how to use it. I've looked everywhere for a website that tells how to use it but i found nothing. If you want to see what my current image resizing dialog looks like click on the link below, save the pic to your hard drive and look at it through a windows image previewer. I dont know if I need to add something to the dialog or if i am missing any code.
Any help would be greatly appreciated.
Heres the link:

I have code to minimize my dialog to the system tray. Right now when the minimize button is pressed, the dialog prompts and asks "Minimize to the System Tray?". I would like to add an extra button to the Title Bar (just to the left of the minimize button) to control sending the dialog to the system tray.
I have searched CodeProject but to no avail.

So the user will have a choice whether they want to minimize to the Taskbar or the Taskbar Notification Area (sometimes erroneously called the tray)? Is that right?

That's right. The way I have it set up now is that when the user clicks the minimize button, a YES/NO message box asks you if you want it minimized to the system tray. If YES it goes to the "Taskbar Notification Area", if NO it is just minimized to the taskbar.
I want another button next to the minimize button that will be used to send the dialog to the "Taskbar Notification Area".

Hello,
I am having problems in justifying a text which is placed in a rectangle. I have placed the text inside the rectangle using DrawText() method, with DT_WORDBREAK flag so that the text can be clipped and can appear in multi lines. If i opt for this, the text is aligned Left or Right. Its not justified. Therez another method of SetTextJustification() which is used with TextOut and extTextOut(), if i use ExtTextOut (since i have to place the text in a rectangle) the text appears in a single line, without any clipping.......this remains a problem. can any 1 provide a solution which can place the text in the rectangle which is justified.
Thanx

I think DrawText and Textout can't justify text.
You can use a RTFControl (Has to be Version 2.0 or higher)
* create an invisible RTF Control (be sure to use RTF2.0 or higher)
* Set Text with SetWindowText
* SelAll
* SetParaFormat with paraformat2.wAlignment to PFA_JUSTIFY
* set target device EM_SETTARGETDEVICE
* set wrapmode
* use EM_FORMATRANGE to draw content to a dc
have a lot of fun

Thanx, but i wanna know can i generate these controls at runtime, bcoz i have to have an unknown number of rectangles at runtime !!!
Thanx
Nadir Maroof

yes you can !
Create one or more instances of CRichEditCtrl !
I would not use the standard create method of MFC because it uses RTF Version 1.0. It is important to create it without WS_VISIBLE Style
To create Version 2.0 or higher you have to use
LoadLibrary("riched20.dll")
see msdn LoadLibrary("riched20.dll")

Hi,
I am searching for a way to connecnt unlimited number of clients to a server.I
Know I can use these ways:
1-To create CAsyncSocket varaibles in array and dynamically.
2-To create CAsyncSocket pointers in a threads.
But I don't know none of them.
Please Help me!
Tell me if there is any good and simple article.
Thanks you.

Search for information on Windows Sockets. You should be able to find examples.
With sockets, on the server side try:
listen(socket, MAX_CONNECTIONS), after the call to bind().
Set MAX_CONNECTIONS with a define statement to some large value. I hope this helps you out.

I must be missing something somewhere, but it isn't obvious to me with such an ambiguous error msg...
I've tried every connutation of line 79 "(WindowOne ->Create(NULL,NULL,WS_CHILD,);", but none seem to help, unless I actually comment it out.
Is there another section of code where I should go to make edit corrections?
I've tried deleting the offending line and recompiling before retyping it back in to no avail.
Any help/advice is greatly appreciated!
The offending code...........
void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,NULL,WS_CHILD,);//line 79
WindowOne ->ShowWindow(SW_SHOW);
}

Try this
CWnd* pWnd = new CStatic;
pWnd->CreateEx
(WS_EX_CLIENTEDGE, // Make a client edge label.
_T("STATIC"),
"Dialog",
WS_CHILD |WS_TABSTOP | WS_VISIBLE |WS_CAPTION,
5, 5, 300, 300,
m_hWnd,
(HMENU)1234);
m0n0

Thanks very much! This works, and I'm sure I will be ale to put it to good use. A question regarding the use of CStatic...
I want to be able to access the window produced as if it were a List box. The item choosen from this list box will be applied to a second window which will bring up the properties of the item chosen from the first window.
Can I do this with the CStatic window just created?
Thanks in advance,
Thomas

i think u r missing a few parameters, just try this one;
void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
Rect rect(100,100,200,200);
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,"Window One",WS_CHILD,rect,NULL,NULL,NULL);//line 79
WindowOne ->ShowWindow(SW_SHOW);
}
You missed out the rectangle, and other few parameters, just try this one out.
Cheers

Sorry i missed a thing, it is;
CRect instead of only Rect in the declaration, now ur code should look like this;
void CSplashScreen::OnGo()
{
// TODO: Add your control notification handler code here
CRect rect(100,100,200,200);
CWnd *WindowOne = new CWnd;
WindowOne ->Create(NULL,"Window One",WS_CHILD,rect,NULL,NULL,NULL);
WindowOne ->ShowWindow(SW_SHOW);
}
Hope this helps,
Cheers
