I appreciate the input, im currently researching the ipc and how this may help my application along. Basically the program allows users to launch a specific executable and use information from ini files (user specified) to pass arguements to the process prior to launching (thus avoiding writing multiple bat files). But after the process is launched the user pretty much looses control of that executable (this is the manufactures fault) and im trying to find a way to give some control back to the user. Basically what im trying to accomplish is getting the process to restart (without shutting down completely) with a new set of arguements thus giving it more functionality.
As i just started reading the about ipc i havent quite come to the conclusion if this will be what i need or not, i have seen that it has the ability to pass info thru networks ect... but havent gotten all the time to read more into it.
If anyone knows how ipc works or any other way to accomplish my task i would appreciate the input.
Thanks in advance

BTW you can also change the values inside the INI file. But then your process has to periodically check the INI file for changes.

Sorry, this should be obvious, but I don't know it.
How do I pause my program execution until another event fires?
Thanks

you have to do nothing, a Windows application sits down waiting for the next event...

In my program, when a specific action is taken, the form generates a tablelayoutpanel. this table layout panel requires, in different circumstances, to have a different amount of cells. The cells need to be of equal size. How would i go about this? I have no idea how to programatically set the amount of rows and columns, is there a way?

Hi,
Could anyone help me?
I'm trying to set a text box so the contents scrolls across the screen (right to left - like a news ticker). I've found some part examples using picture boxes, but was hoping for something more basic, with just a textbox/label etc - and a timer. It doesn't matter if the motion is jerky - so long as it works!
I was thinking it would be something like sending the text to a temp location then on a timer tick it changes whats in the text box so everything it one/two characters further over. I'll need to make sure the whole message is displayed before the first letter reappears at the start.
Any help would be much appreciated
I'm using Visual Studio 2003 (VB.net)
Many thanks
Matt

Might be a bit messy, but i did throw it together in a couple of mins so...:
Dim text As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load<br />
text = Me.Label1.Text<br />
End Sub
Dim leftbound As Integer = -1<br />
Dim Right As Boolean<br />
<br />
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick<br />
If Me.Label1.Text = "" Then<br />
Me.Label1.Location = New Point((Me.Width - leftbound), Me.Label1.Location.Y)<br />
Right = True<br />
End If<br />
If Me.Label1.Location.X = leftbound Or Me.Label1.Location.X = leftbound + 1 Then<br />
If Me.Label1.Text <> "" Then<br />
Me.Label1.Text = Label1.Text.Remove(0, 1)<br />
End If<br />
Right = False<br />
ElseIf Me.Label1.Text = text Then<br />
Right = False<br />
Me.Label1.Location = New Point(Me.Label1.Location.X - 2, Me.Label1.Location.Y)<br />
ElseIf Right = True Then<br />
If Me.Label1.Text.Length + 1 <= text.Length Then<br />
Me.Label1.Text = text.Remove(Me.Label1.Text.Length, text.Length - (Me.Label1.Text.Length + 1))<br />
Me.Label1.Location = New Point(Me.Label1.Location.X - 1, Me.Label1.Location.Y)<br />
End If<br />
End If<br />
End Sub

Thanks, I've tried that - however it isn't quite what I was after. The label box in that example has to be big enough for the for the entire message els it wont all be displayed. Say the label is wide enough for 30 characters, but the message is 45 - is there a way to scroll the entire message across the box before restarting?
Thanks for your help

Dim s As Integer = 70<br />
text = Me.TextBox2.Text.PadLeft(s) & Me.TextBox2.Text.PadLeft(s)<br />
Me.TextBox2.Text = text<br />
<br />
Dim c As Integer = 0<br />
<br />
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick<br />
<br />
Me.Timer2.Interval = 60<br />
If c = text.Length Then<br />
c = 0<br />
Else<br />
c += 1<br />
Dim a As String = text.Remove(c, text.Length - c)<br />
Me.TextBox2.Text = Mid(Me.TextBox2.Text, 2) & a.Remove(0, a.Length - 1)<br />
End If<br />
<br />
End Sub
Note: Set s until you get desired effect

Thanks for that.
It scrolls perfectly
VB doesn't seem to like this line though
text = Me.TextBox2.Text.PadLeft(s) & Me.TextBox2.Text.PadLeft(s)
Also I can't see how to change the text in the scroll, I tried but after the first time it scrolls I just get "Form1Form1" etc repeated.
Thanks again

I'm not sure how to fix either of those issues as i didn't have either of them, sorry about that.

Ok thanks
It didn't like that first line as it said "text" had not been declared.
I'll have a play around with it.
Edited to add:
I've got it just scrolling my text now - it only scrolls once though then the box stays blank, so I still need to have more of a play around
Thanks

The only way I got it to accept those two lines were to put it inside the windows form generated code.
It works fine then - just adds whatever text I give it to the form caption bar too!

hey ive been messing around with vb .net 2005 and i got an idea to attempt a program that uses voice recognition. ive looked around and ive seen code in other languages and not really vb .net (i saw one in vb 6 but i dont have that). i was wondering if anyone could point me in the right direction of where to begin in trying to start voice recognition, thanks

Do a search on MSDN for Microsoft's Speech SDK (free to download) ..
Once installed you can embed speech into your vb.net applications ...

|

Yes .. there's a pretty comprehesive help file with the SDK ...

Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim SpFlags As SpeechLib.SpeechVoiceSpeakFlags = SpeechLib.SpeechVoiceSpeakFlags.SVSFlagsAsync
Dim Voice As SpeechLib.SpVoice = New SpeechLib.SpVoiceClass
' Speak introduction
Voice.Speak("Hello")
Voice.Speak(Me.TextBox1.Text)
and add references Interop.SpeechLib
there is a site coding4fun where i found out about this one hope this helps

This example is for getting an app to talk, not to get it to do recognition.
