This is obviously a waste of time, but it won't cause your issue.
And this is a winforms app, and this code does not run again ? What's your selected index changed look like ?

Yes I am a little off and on with the new object setting depending on how I set the object later. I believe this was written before I quit with the extra step.

If uxDepartments.SelectedIndex > 0 Then<br />
uxDepartmentEdit.Text = CType(uxDepartments.SelectedItem, DataRowView)("DepartmentName").ToString.Trim<br />
uxAddDepartmentName.Enabled = False<br />
uxUpdateDepartmentName.Enabled = True<br />
uxDeleteDepartmentName.Enabled = True<br />
<br />
Else<br />
uxDepartmentEdit.Text = ""<br />
uxAddDepartmentName.Enabled = True<br />
uxUpdateDepartmentName.Enabled = False<br />
uxDeleteDepartmentName.Enabled = False<br />
<br />
End If<br />

Hi,
I have put in a custom Context menu in the webbrowser control for VB 2005. I am using the following to find out which item was clicked on:
in the document complete event:
oDoc = wBrowser.Document 'Odoc is a System.Windows.Forms.HtmlDocument
Private Sub oDoc_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.HtmlElementEventArgs) Handles oDoc.MouseDown
'Here is it's an input element? if yes we want to show the normal windows options....
If e.MouseButtonsPressed = Windows.Forms.MouseButtons.Right And oElement.TagName = "INPUT" Then
wBrowser.IsWebBrowserContextMenuEnabled = True
Else
wBrowser.IsWebBrowserContextMenuEnabled = False
End If
Dim MPoint As New Point(e.MousePosition.X, e.MousePosition.Y)
oElement = wBrowser.Document.GetElementFromPoint(MPoint)
End Sub
Private Sub oDoc_MouseMove(ByVal sender As Object, _
ByVal e As System.Windows.Forms.HtmlElementEventArgs) Handles oDoc.MouseMove
' On Error Resume Next
Dim MPoint As New Point(e.MousePosition.X, e.MousePosition.Y)
'e.MousePosition.X, e.MousePosition.Y)
oElement = oDoc.GetElementFromPoint(MPoint)
end sub
Private Sub cmRightClick_Opening(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles cmRightClick.Opening
If Not IsNothing(oElement) Then
If oElement.TagName = "IMG" Then
imageMenu.Enabled = True
Else
imageMenu.Enabled = False
End If
If oElement.TagName = "A" Then
linkMenu.Enabled = True
Else
linkMenu.Enabled = False
End If
End If
The code works fine in some cases but in others (such as a facebook profile page), if I click on the profile image, the OElement tagname is "Body" and neither of "IMG" or "A". Any Ideas? thanks

 Hi,
I am getting the this error :Object Reference not set to an instance.
when i debug i came to know that 'qry' is not initialized.Bui have initialized it.Don't Know why 'qry' is not getting initialized.
my code is:
Dim rdoSex As String
Dim CreateDate As String
Dim qry as String
Dim i As Integer
CreateDate = Now.Date.ToString()
If rdoMale.Checked = True Then
rdoSex = "M"
ElseIf rdoFemale.Checked = True Then
rdoSex = "F"
Else
rdoSex = "NA"
End If
Try
qry = ""
qry = "insert into T_STU_MASTER values('" &CreateDate & "','" & txtStudentName.Text.Trim() & "','" & txtFatherName.Text.Trim() & "','" & txtMotherName.Text.Trim() & "','" & rdoSex & "','" & dtpDOB.Text.Trim() & "','" & cmbVillage.SelectedItem.ToString().Trim() & "')"
cmd = New SqlCommand(qry, con)
'//Error is thrown in above line that qry is null while i have initialized it
i = cmd.ExecuteNonQuery()
If i > 0 Then
MsgBox("Information Saved Successfully!!!")
End If
Catch ex As Exception
MsgBox(ex.ToString())
Finally
con.Close()
End Try

As far as I can see, that's not possible.
Are you absolutely certain that it's not the con variable that isn't initialised?

Are you *certain* ? Although this is pretty terrible code, I don't see any way that qry could be uninitialised. Try stepping through with the debugger and checking variable values, I think it's con that is null, it's the only thing I can not see initialisation code for.
You need to read this[^]. You also need not to initialise variables over and over ( you set qry to "", then in the next line, change it ). Also, rdoSex is not a radio button. Hungarian notation is not generally used nowadays anyhow, but that's just wrong.

can somebody help me. i made a project that compose of many forms., in the 2nd form, it has timer that has only 30 min. and it will stop if 30 minutes is over. But if the 30 minutes is not yet over and i already reach the last form which is form10, the timer in the 2nd form should stop and the 2nd form will be hide. How can i do it?
the project that i am making is an IQ test, and it has many pages, when the test is answered already, the timer should stop..
can somebody please help me about my problem.. thanks!

You end up with 10 forms visible ? Sounds like you really want a wizard type interface.
Use delegates to get form10 to tell form2 that the timer is no longer required, and to make that form hide.

no, the other forms will not be visible. the only visible form is the 2nd form, the form that has timer.
how to use delegates? can you tell me the codes for it?
|
|
|
|
|
I don't understand completely:
If all of these forms are in the same application then why don't you have form10 call form2's timer
and tell it to stop.

This is better asked on the ASP.NET forum.
I have no idea, I don't use any of the built in wizards, I write my own code.

hi all,
How would one go about replacing a character in a string with a space where the character is not in the range of a-z or A-Z or 0-9 ???
the following Code did not have the planned outcome...
Dim cleanString As String = [String].Empty<br />
Dim reg As New Text.RegularExpressions.Regex("[A-Z]|[a-z]|[0-9]")<br />
Dim coll As Text.RegularExpressions.MatchCollection = reg.Matches(LineText, )<br />
For i As Integer = 0 To LineText.Length - 1<br />
MsgBox(coll(i).Value)<br />
If (coll(i).Value = [String].Empty) Then<br />
cleanString = cleanString + " "<br />
Else<br />
cleanString = cleanString + coll(i).Value<br />
End If<br />
Next
the result was not pritty.... it removed spaces as well... how do i keep spaces and replace (NOT REMOVE) other characters with a space???
Thank you in advance.

Try using the Regex.Replace[^] function.

With a single line of code:
Dim cleanString = Regex.Replace(LineText, "[^A-Za-z\d ]", " ")

When viewing the message you want to reply to, simply click the "reply" link and write the new message. It will automatically be appended to the thread with the appropriate indenting level based on the message to which you were replying.

Why is this not a complete waste of code ? I don't see what it could possible achieve?

Hi,
I beleive this sample code is in C#:
string cleanString = String.Empty;<br />
Regex reg = new Regex("[A-Z]|[a-z]");<br />
MatchCollection coll = reg.Matches(<mystringgoeshere>);<br />
for(int i = 0; i < coll.Count; i++)<br />
{<br />
cleanString = cleanString + coll[i].Value;<br />
}</mystringgoeshere>
See, i want to remove all characters that do not fall in the A-Z or a-z OR 0-9 category AND replace it with a space...
example test123t3er = test t er
Am i wrong in saying that the Regex reg = Regex("[A-Z]|[a-z]") CAN IT BE: Regex reg = Regex("[A-Z]|[a-z]|[0-9]") ???
AND the cleanString = cleanString + coll[i].Value;
CAN I DO A TEST: IF(coll[i].Value == String.Empty) THEN cleanString = cleanString + " " ELSE cleanString = cleanString + coll[i].Value ???? - in this way i add space if the character is not in the above category????
So please help me convert the very top section of code and i will build from there...
Thank you in advance...

(via Instant VB):
Dim cleanString As String = String.Empty
Dim reg As New Regex("[A-Z]|[a-z]")
Dim coll As MatchCollection = reg.Matches()
For i As Integer = 0 To coll.Count - 1
cleanString = cleanString & coll(i).Value
Next i

The same way you get all other events: Select the control for which you want to insert an event on the left combobox above your code-window, then choose the event from the combobox on the right hand side.
