hi
What do you want to do with a HDD Serial number, for sure it changes when the HDD get formated. its not Stable, if you want this for Software protection thing, then i think you should go for Processor ID, that will never change.
Thanks

hi,
Use the below mentioned code:
Dim i As Integer = 0
Private Sub TextBox1_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox1.KeyPress
If e.KeyChar = "a"c Or e.KeyChar = "A"c Then
i += 1
If i >= 3 Then
MsgBox("Sorry, letter 'a' has already been used Twice")
e.Handled = True
End If
End If
End Sub
I hope this would be helpful.

--> How can i restart or shutdown my computer from the dotNet application..?

Use Shutdown.exe
process.start("shutdown","-r")

--> What do you mean by "-r" in the second argument..?

Usage: shutdown [-i | -l | -s | -r | -a] [-f] [-m \\computername] [-t xx] [-c "comment"] [-d up:xx:yy]
No args Display this message (same as -?)
-i Display GUI interface, must be the first option
-l Log off (cannot be used with -m option)
-s Shutdown the computer
-r Shutdown and restart the computer
-a Abort a system shutdown
-m \\computername Remote computer to shutdown/restart/abort
-t xx Set timeout for shutdown to xx seconds
-c "comment" Shutdown comment (maximum of 127 characters)
-f Forces running applications to close without warning
-d [u][p]:xx:yy The reason code for the shutdown
u is the user code
p is a planned shutdown code
xx is the major reason code (positive integer less than 256)
yy is the minor reason code (positive integer less than 65536)

This is a "poor-man's" solution and only works on XP and above.
Using the Windows API function ExitWindowsEx[^] would be the correct way to go here.
|

|

Wouldn't ExitWindowsEx P/Invoke API help you out?

Hello every one,
I am making a application similar to paint brush...
Hear i am finding one issue that pen width '1' is too small and '2' is really big...
is there any way i can have width between 1 and 2?
regards
Nishkarsh

Hi,
Pen width takes a floating-point number (a Single in your language). Did you ever consider
and try something like 1.5?
|
|
|
|
|
It is taken as a single in VB.net.
I tried 1.5 and all... it did not threw any error but the size also did not changed..
|
|
|
|
|
You could try setting the Smoothing Mode of your graphics object to be of an antialiased:
g.SmoothingMode = SmoothingMode.HighQuality
That will deal with 1/2 pixels well, but is a bit slower.
|
|
|
|
|
you may not notice a difference between 1 and 1.5 when drawing a horizontal or vertical line,
after all the pixels of your screeb are discrete, so it will hit either one row of them, or two.
Things should be different though for slanted lines, circles, etc,
|

Thanks a lot to both of you..

Hi Luc
i think i will need a bit more clarity on pen width..
there is for sure some difference between size 1.6 and 2.0 . But there is a huge difference between 1.5 and 1.6 (i am using huge in relative terms only.. )...
This is making the line width uneven in the application...
is there some thing more i need to look at or i am missing out???
Regards
Nishkarsh

Hi,
I can't help you with detailed information, I haven't done much with pen width yet.
I would look for some properties on either Pen or Graphics that relate to drawing quality,
such as the smoothing thing Jasey9 mentioned. To name a few more: Pen.StartCap, EndCap, LineJoin,
MiterLimit; and Graphics.InterpollationMode, PixelOffsetMode.
You may discover computer graphics is a complex subject...

Hi,
read the little error message and apply a little code correction accordingly.
I hope you did initialize your Graphics object "g", your string "string1" and your Font "Font1".
How do you want us to help you if you don't provide details on the symptoms?

hi,
i read the error message, which give "NullReferneceException" . I does not use New keyword for graphics object.(or not initialize the object g).i have no idea for this thing. So how can i initialize the object g for measure string size ?
in code snippet(in previous post) string 1 and font1 contains related value.

Try something like:
using bmp as new bitmap(1,1)
using g as graphics=graphics.fromimage(bmp)
[Measure string here using g]
end using
end using
But you will be better off using the correct graphics canvas to use - if you are drawing text to an image, use that image instead of creating a new one like the above example.
