for getting current resolution of system u can use
Screen.PrimaryScreen.Bounds.Height;
Screen.PrimaryScreen.Bounds.Width;
to change the resolution of system there is no direct way u have to use some window API's

It is generally bad practice to change the resolution on your users' machines. However, here is a good article about how to do it in C#:
Using P/Invoke to Call Unmanaged APIs from Your Managed Classes[^]

Use overload of Process.Start that takes an arguments parameter.

Change the main method of application to Main(String[] args). args will conatin the passed command line parameters.

Are you using the Enable Visual Styles in your application?
[STAThread]<br />
static void Main() <br />
{<br />
Application.EnableVisualStyles();<br />
Application.Run(new Form1());<br />
}

to remove. go to publishing Designer selects the form and change the property ControlBox to false.
to intercept.
public const int WM_SYSCOMMAND = 0x0112;
public const int SC_CLOSE = 0xF060;
protected override void WndProc(ref Message m)
{
if( m.Msg == WM_SYSCOMMAND)
{
if( (int) m.WParam.ToInt32() == SC_CLOSE )
{
if (ProjectIsOpen)
{
return;
}
else
{
this.Close();
Application.Exit();
}
}
}
base.WndProc (ref m);
}

private const int SC_MINIMIZE = 0xF020;
private const int SC_RESTORE = 0xF120;
private const int MF_GRAYED = 0x1;

[System.Runtime.InteropServices.DllImport("user32.dll")]
private static extern int EnableMenuItem(IntPtr hMenu, int wIDEnableItem, int wEnable);
private void Disable_opt()
{
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_CLOSE, MF_GRAYED);
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MAXIMIZE, MF_GRAYED);
EnableMenuItem(GetSystemMenu(this.Handle, false), SC_MINIMIZE, MF_GRAYED);

Perhaps you should ask this in the C forum instead.

Hi Buddies,
Could somebody help me in implementing a screenlock?
What I'm trin' to do is, if the user is not interacting with the system for a stipulated time I need to lock the screen, thereby forcing the user to enter his password to unlock the system.
Thanks to all in Advance

Fast solution: create a full screen TopMost window with passwordbox.
All the best,
Martin

HI GUYS,
FIRST OF ALL THANKS FOR THE REPLY.....
ISN'T IT POSSIBLE TO CALL SOME WINDOWS API THAT CAN DO THIS JOB FOR ME?
BUT I DONT HAVE ANY IDEA OF WHICH API OR HOW?
OR JUST PUT IT THE OTHER WAY...
HOW DOES Windows SCREENLOCK WORK? ANY IDEA?
|
|
|
|
|
Hi!
The corresponding Win32 function is called LockWorkStation and located in user32.dll.
You can simply use this code:
using System.Runtime.InteropServices;
public class ScreenLock
{
[DllImport("user32.dll")]
public static extern bool LockWorkStation();
}
Regards,
mav

thanks mav.
But how do I know the system idle time?
Does the API does it by itself(I hope no).....?
If I use Application.Idle definitely its not gonna to work.
Is there anything like System.Idle  ?
thanks once again for the help & still look forward to you suggestions...

Hi,
Can you please tell me how can I go to the last visited tab (not the first one, as the default tabControl behaver is) when the current tab is removed?
Your help would be greatly appreciated.
|
|
|
|
|
hi,
try saving the index of the last visited tabcontrol in a global variable. it is easy to do. Declare a global variable and use the tab index change event. and asign the past index to the variable when this index changes to another.
hope it helps

to use a variable doesn't just solve the problem. for instance if you turn off 2 or more tabs consecutively it won't work.
if you use a routine that allows to include and to remove several tabs then it should use a LIFO.
when eliminating a tab it removes all the occurrences of this in the LIFO and go back to the last tab of the LIFO.
