Hi,
I am having some Buttons and Radio Buttons on my Form. I am using UP and DOWN arrow keys as Hot keys for some Buttons and I want to assign SHIFT + UP and SHIFT + DOWN keys as Hot keys for some other buttons. How can I do this? The Code for UP and DOWN arrow keys is given below:
Protected Overrides Function ProcessCmdKey(ByRef msg As System.Windows.Forms.Message, ByVal keyData As System.Windows.Forms.Keys) As Boolean
Select Case keyData
Case Keys.Up, Keys.Down, Keys.Left, Keys.Right ' (Left/Right also navigate controls)
If keyData = Keys.Up Then
Button1.PerformClick()
ElseIf keyData = Keys.Down Then
Button2.PerformClick()
End If
Return True
Case Else
Return False
End Select
End Function

Hi,
assumming you have a DataTable bound to your grid you will have to set the RowFilter of its DefaultView to a string representing your cirteria. A description on how the filter must look like can be found here[^]. You could also have a look at one of my articles[^] dealing with this or probably even just use the component.

OK, before you read any further I do not want to rewrite a web server. What I want to do is have my application sat in the system tray and to have a port open to which other clients can connect. When they connect my little app sends it's interface in the form of html files to the client (lets say a web browser on a PDA). The question is: where is there any tutoials on a client/server architecture which transmits web pages?

Anyone know how to programatically create a cursor?
A simple method (Or code to place in a method) like: Function CursorFromBmp(ByVal CursorPicture As Image, ByVal HotSpot As Point) As Cursor would be nice. The cursor should look exactly like the image. The Transparancy Color should be Color.Transparant.

Whats the difference between Windows Script and VB Script?
|
|
|
|
|
Window Script is the script engine. It can use either of the languages VBScript or JScript.

I just got myself a version of Installshield 11. I'm creating a custom action in the installer using VB Script. How can I execute a file with parameters using VB Script. Do I have to use Wscript.Shell??
|
|
|
|
|
Don't know much about InstallShield, but about vbscript, yes, you need to use the WScript.Shell object like:
<br />
set ws = Wscript.Shell<br />
arg1 = ws.Arguments[0]<br />
arg2 = ws.Arguments[1]<br />
and play with the argument values. I haven't checked the syntax for accuracy, but this should point you in the right direction.

if my vb.net form is trying to copy a file to a destination where the file already exists, how would i get it to rename the new file to something different?
eg: if "C:\test.txt" exists then it will rename it to "C:\test01.txt"
and if those two exist then it will rename it to "C:\test02.txt"
so you could get
"C:\test01.txt"
"C:\test02.txt"
"C:\test03.txt"
"C:\test04.txt"
..........
etc etc

hi
search the destination for the file.
i.e. if you are copying the file "C:\test.txt" user the following :
System.IO.File.Exists("c:\test.txt") , this will return true if the files
exist

already know that code, sorry but its not what im looking for
im not looking for it to check for it and if its there then it will not copy
im looking for code that if the file is there, it will rename it and send in the same file but rename it
example: when you copy a file in windows and paste it a couple of times
it will make copies like this
Copy of Test
Copy (2) of Test
Copy (3) of Test
etc etc
im trying to make my program do that

You will have to set up a loop that checks for existence of the file and rename it if necessary, like:
<br />
Dim strExtnOnly as string = ".txt"<br />
Dim strFileNameOnly as string = "test"<br />
Dim blnDone as Boolean = false<br />
Dim strDest as string = "Your destination folder"<br />
dim intCounter as integer= 1<br />
<br />
do while blnDone = false<br />
strFullPath = strDest & "/" strFileNameOnly & strExtnOnly <br />
if File.Exists(strFullPath) then<br />
intCounter+= intCounter<br />
strFileNameOnly = strFileNameOnly & CStr(intCounter.ToString.padleft("0",2)) ' something like that<br />
else<br />
blnDone=True<br />
end if<br />
loop<br />

I would like to increase field length of a bound cell more than 50 when using true DBGrid (Component One). I used datawidth propertie of it. But it could not increase the field size.
|
|
|
|
|
It's probably because that's the maximum length specified for the field in the database.

Does anyone know how to or know where to find an article explaining converting MSIL code to VB or VC# (Or just about any other language, actually) code. The MSIL I want to convert is the Byte Array returned from he MethodBody.GetILAsByteArray Function. MethodBody is a type in the System.Reflection namespace.
