I've got a huge headache right now (side-effect of being at work!), so I could be wrong here, but I don't think there is a way for you to do that.

Hi
Tanx,
what is the usage of Me.Events?
Can't it help me?
|
|
|
|
|
Nope. It's a Protected, ReadOnly property that returns an EventHandlerList object. The EventHandlerList has no enumeration capabilities since it is not a true collection.

I don't know of any websites that offer complete tutorials. A better bet would be to exvaluate your own skill set against what you find at a book store. And for how long that will take? Only you can answeer that question.

 G'day and thanx in advance for anyone replying to my question.
Being a VB.Net newbie, I am having trouble using basic text extraction from a richtextbox.
As the user types into a richtext box I have a tool tip that pops up when the user hits '(' and closes on the ')' key hits. It appears just below and to the right of the current caret location in the richtextbox.
I would like to be able to extract the last word typed just prior to hitting the '(' key, so I know what they are trying to do and can provide appropriate tips in the tooltip.
Can anyone help me with a short example of extracting text from the current caret position - 1, to the last '$', " " , "<", ";" entered before the current caret position.
Sorry if it's a real Newb question, .NET has so many bloody classes, I'm sure there's a simple way to do it, but I don't know where to look.
Cheers, Craig.

The current Caret position is always stored in the SelectionStart property of the RichTextBox control.
Now, the Text() property will return the text as a String object. You can then use its LastIndexOfAny(char(), startIndex, count) method, using 1 for startIndex and the value of SelectionStart for the count, to find the index of the last character, which you've already supplied in your post. This will give to the starting position and ending position of the word your looking for.

G'day Dave,
Thanks heaps for a super fast response, and sorry for my tardiness in thanking you.
I'm stunned at how quick I have received help from these forums. It's guys like you, willing to read these and provide help, that make it all work.
Thanks again.

Hi Craig
Your question is similar to having autoselect in a Combobox.You can extend the same idea over here using the keypress event.
Private Sub TextBox1_Keypress(ByVal sender As System.Object, ByVal e As KeyPressEventArgs) Handles TextBox1.KeyPress
If Char.IsControl(e.KeyChar) Then Return
With Me.TextBox1
Dim ToFind As String = .Text.Substring(0, .SelectionStart) & e.KeyChar
End With
End Sub
the variable toFind will have previous characters in textbox and the currently typed character.for eg:- if the textbox contains "chr" and user types "i" then the value of to find will be "Chri".
I think this should solve your problem.

G'day Mandar,
Thanks very much for that. I haven't tried it yet, but it reads well, it's simple and seems to make sense. You're obviously skilled in VB .NET
I did pick up on a neat little trick you're using, which I havn't seen anywhere else....the 'With' and 'End With' Statement. It appears from your code that it basically saves us from typing Me.TextBox1 within the 'With'-'End With'. That in itself is a bit of gold !
With Me.TextBox1
Dim ToFind As String = .Text.Substring(0, .SelectionStart) & e.KeyChar
End With
Also, just a quick comment about how fast I received 2 very clever responses to my question. I received the first response in a matter of an hour or two and the second not long after. The 'CodeProject' has been a huge help. Cheers to the admin as well.
Craig.

I'm writing an application(VB) that connect to a trading server, I have the following code, but I am havign some strange behaviour:
Private Sub cmdConnect_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdConnect.Click
' assume this is a non Financial Advisor account. If it is the managedAccounts()
' event will be fired.
m_faAccount = False
m_dlgConnect.Show()
If m_dlgConnect.ok Then
With m_dlgConnect
Call TwsCtrl.connect(.hostIP, .port, .clientId)
End With
End If
End Sub
When this code is executed, the result that I want, namely to logon the server, I am having to run this code twice, I mean it works, but The command button that I press to execute this code requires me to have to press it twice, requiring this module to execute twice???? I cant quite figure why I get this strange behaviour??

Since you've provided no information about the service your trying to connect to and what this .connect method does exactly, there's nothing anyone can tell you to help.

Either you did something wrong or your expectation of what it should do are wrong. Without a sample of the code you tried or what you wanted it to do, there's nothing we can really comment on.
Dim myDouble As Double = 3.1415927
Console.WriteLine( "myDouble = " & myDouble.ToString() )

I load Images into ImageList, but in runtime i checked there is no image in ImageList.. What s problem thank u
|
|
|

Since the ImageList control is pretty finicky to begin with, it's nearly impossible to tell you what wrong without seeing any of your code that is filling the ImageList. Another question would be, are you using Application.EnableVisualStyles?
