This is a complex question, no forum reply is gong to answer it. You basically need to detect shapes and define rules by which you work out what 'equal' means ( i.e. the same sort of shapes, etc ).

Do you mean auto repeat ? Not sure that you can, except that you can ignore key presses that are the same, but what if someone wants to type 'aardvark' ?

You could set the KeyPreview property of the form to True, trap function key presses in the KeyDown event of the form, set a flag to indicate the last function key pressed, and then review the flag the next time KeyDown is triggered to see if that function key was pressed twice in a row. And then, as needed, suppress the key press if you don't want it pressed twice in a row. For example, something like the following in the form's KeyDown event might get you started...
If e.KeyValue = Keys.F4 Then
If mb_Key4Pressed Then
e.SuppressKeyPress = True
Else
mb_Key4Pressed = True
End If
Else
mb_Key4Pressed = False
End If

Please don't spam the whole site before bothering to search the articles. There's tons of info on the site already on this. DirectX is what you use.

Hi,
Have a treeview control and can change the selected node to a (system installed truetype) font like this
trvFonts.SelectedNode.NodeFont = New System.Drawing.Font("Times", ntNodeFontSize)
'FOLLOWING REQUIRED FOR BUG (LARGER TEXT IN NODE WILL CROP WITHOUT THIS)
trvFonts.SelectedNode.Text &= String.Empty
Is there any way (anyone know of a way) that i can use a postcript font (pfb/pfm) from a file (not installed), or even an installed postcript font to use in my treeview or any windows forms control?
Thanks for anyhelp with this
Regards

Hi,
AFAIK you can't get the public IP address programmatically without the help of some web site.
Here is one for you: http://www.perceler.com/tools1.php[^]
You could use the HttpWebRequest class and GetResponse() method to access such page programmatically.

Hello every one...
I want to know the difference between
timer.enable=true & timer.start
timer.enable=false & timer.stop
I have two different timers on a form one fires at every 5 sec (timer1) and other every 20 sec (timer2)...
I want the timer2 to be pause when timer1 is fired and continue after the codes in timer1 execute are over
Timer1_Tick
(
'Pause tumer2
----
----
Some codes
'Continue timer2
)
how can i do that
Regards
Nishkarsh

Both are same thing
timer.start raising the Elapsed event by setting Enabled to True.
while timer.stop raising the Elapsed event by setting Enabled to False.
for more details see MSDN[^]

Hai.I want to know how to handle printing when the text exceeds one page.
I am Using Draw String Method .
Single Page Printing is not a Problem.But when it exceeds a Page what is the best way to Display the Remaining text in the Next Page?
|
|
|
|
|
Make an area (such as a rectangle) on the page, then use MeasureString[^] to determine how many characters will fit in that area. Next, print that many characters, and save the remaining characters for the the next page. You can put that into a loop, each time making a new page, until all characters have been printed.
|
|
|
|
|
You check for a condition that says that you need a new page, then use HasMorePages = True to tell your program that there is more to be printed.
For i As Integer = curLine to LinesREQ
Do While (pageLine <= linesPerPage) And (CurRow <= LinesREQ)
' Printing logic here
If pageLine > linesPerPage Then
e.HasMorePages = True
Exit For
Else
e.HasMorePages = Flasle
End If
Loop
Next
I don't speak Idiot - please talk slowly and clearly
