You're question would be better handled in the ASP.NET Forum. Regardless of the language it's written in...

Your IIS is not set up to run ASP.NET pages. You have to re-register ASP.NET in IIS.

Hi,
How do we detect arrow keys(up,down,left,right) in a vb.net application? Also, what are the code values for these keys?
The application consists of a form that has an image control on it. When the user presses the right or left arrow keys, the image is supposed to move to the right or left.
|
|
|
|
|
Override the OnKeyDown method in the form. The System.Windows.Forms.Keys enumeration contains all the key codes, I think the up, down, left, right are something like Keys.Up etc.
Note, you can't use the keypress because it doesn't trap function / arrow keys for some reason.
Protected Overrides Sub OnKeyDown(KeyEventArgs e)
Select Case e.KeyCode
Case Keys.Up
' Move image up
Case Keys.Down
' Move image down
Case Keys.Left
' Move image left
Case Keys.Right
' Move image right
End Select
End Sub

Yup, thank you
I tried the code and it works.
The note on keypress is useful also because I was wondering why keypress does not work. =)

u can look for the error where u are creating/adding items to the index...
these errors are of primitive kind...

hi,
How to delete multiple records in datagrid using Checkbox like yahoomail in vb.net.
If possible, then give me code for that.
It's urgent.
Thanx in advance.

i will not give u the code...use your wits ....that's important...
first think, what u want to do ... u want multiple row deletion(in the front end---and of course u also have to update database)...
pertaining to each row u select, the database should be updated(or deleted)...
if u want to use checkboxes,it's fine...
each checkbox is pertaining to a row, and hence are linked to the database....
if i am not clear,u can mail me at praslearn@yahoo.co.in

Hi, I created a .dll that contains various forms I wish to keep outside the main .exe
This Sub in my .exe's main form calls: Show_Form1()
Private Sub Show_ThisForm(ByVal sender As Object, ByVal e As EventArgs)
ThisForm.Show_Form1()
End Sub
WHERE .dll's code is:
Public sub Show_Form1()
Dim ThisForm as new Form1
Form1.ShowDialog()
End sub
Form1's Load Sub is this:
Private Sub Base_Load(ByVal sender As Object, ByVal e As EventArgs) Handles MyBase.Load
Text &= "please, wait..."
Show()
Refresh()
Cursor = Cursors.WaitCursor
If Con.State <> 1 Then
MsgBox("The Server is not available", MsgBoxStyle.Critical, "Cannot Proceede")
Close()
Else
Try
Retry:
myClient.DownloadFile("http://www.site.com/", ResFile)
If Init_Parser() = True Then
Text = "Ready!!!"
Get_Info()
Else
Close()
End If
Catch
If MsgBox(Err.Description & Chr(10) & "Would you like to try again?", MsgBoxStyle.Question + MsgBoxStyle.YesNo, "Connection failed") = MsgBoxResult.Yes Then
GoTo Retry
Else
Close()
End If
End Try
Cursor = Cursors.Default
End If
End Sub
Now, here is the THING: If (myClient.DownloadFile) succedes everything goes just fine, but if it fails then my .exe's main form minimizes and the programe start using all CPU power(will not release it)
If I press (pause) to debug, it stops at this line (***)
Public sub Show_Form1()
Dim ThisForm as new Form1
Form1.ShowDialog() (***)
End sub
I have no idea what's going on, can anybody help?, please!!!
In theory, Form1 should close and the .exe's main form should regain focus

You've created an endless loop with the combination of structured exeption handling (SEH = Try...Catch) and the GoTo Retry statement. You really should not use GoTo especially when you redirect the code back into the Try block.
Restructure the code and see how you go.

First of all, Thank you for your help. I just noticed that I did not explain the issue properly.
When myClient.DownloadFile fails, the execution goes into the CATCH statement, and asks the user if he wishes to try again. The problem occurs when the user press's NO; if so, the only line of code that is executed is:
Close().
skiping the GoTo statement.
The entire Base_Load sub completes (I could not detect the the endless loop, but, if this was the case, the execution would reamin between the Retry and the GoTo statements. is this not right?). Since both the .dll project and the main app belong to the same solution, I can debug both projects simultaneously; if a endless loop were created the debuger would pause(on my request)execution in any of the lines in between the loop(**)
Try
Retry: '(**)
myClient.DownloadFile("http://www.site.com/", ResFile)
If Init_Parser() = True Then
Text = "Ready!!!"
Get_Info()
Else
Close()
End If
Catch
If MsgBox(Err.Description & Chr(10) & "Would you like to try again?", MsgBoxStyle.Question + MsgBoxStyle.YesNo, "Connection failed") = MsgBoxResult.Yes Then
GoTo Retry '(**)
Else
Close()
End If
End Try
instead of in the .exe's main form line: (***)
Public sub Show_Form1()
Dim ThisForm as new Form1
Form1.ShowDialog() (***)
End sub
Please, do not missunderstand me, I am not, by any means, proud of my "code", nor refusing to modify it. I am trying to understand what the problem is so that it would not bit me again
By the way, the only reason why a I using .ShowDialog instead of .Show is because the user must resolve that dialog in order to continue working with the .exe (is this approach wrong?)
Once again, thanks a lot for helping me learn how to Fish your are very kind.
