It must be due to 'index' not being declared.
Try:
For index As Integer = gNum To 1 Step -1

Replace them with a DataGridView and scroll that. Two text-columns should do the trick

That only works well when the two texts have the same number of lines, and the lines of both texts are supposed to match up. The OP wasn't clear on this at all, it could equally well be about a table of content and the content itself (like the "Document Map" Word offers).

Needn't be the same lines, but there would have to be a relation between them. That's what I expect when someone wants to scroll the contents of two different containers simultaneous. It'd work best if both have an equal amount of lines, but the same applies to a textbox.
In that sense, a property-grid looks like two scrollable textboxes to me. One line, one record

Private Sub ListBox1_SelectedIndexChanged(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles ListBox1.SelectedIndexChanged
ListBox2.SetSelected(ListBox1.SelectedIndex, True)
End Sub
If there is a chance that the two lists could have differing item counts then use the Try Catch block to avoid selecting an invalid index.
Good luck!
It was broke, so I fixed it.

Unfortunately a WinForms ListBox does not offer scroll events, so the only technique I'm aware of is by overriding its WndProc. Here[^] is an example (it is using C#, you can do the same in VB.NET).
Once you got scroll events, you can have the second ListBox mimic the scrolling of the first. You can also do it both ways, but then you probably need to be careful and avoid eternal loops.

Hello,everyone! I've knowan how to click treenode to make tabpages selected and show, but I don't want users could click the tabpage and selected one of them. I searched in internet and found that it should use a intenger such as "tab = 1" in some Tabcontrol and Tabpage events like this webpage said whick use TabPage1_Validating & TabPage1_Enter like below :
Private Sub TabPage1_Validating(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles TabPage1.Validating
If tab = 1 Then
e.Cancel = True
Else
e.Cancel = False
End If
End Sub
Private Sub TabPage1_Enter(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TabPage1.Enter
tab = 1 ' setting the selected tab when user gets back to this tab
End Sub
I tried it and now the tabpage could not click,but when I clicked treenode, it could not selected tabpage too.In fact,I didn't understand how the code in the webpage made tabpage disable click after I looked up in MSDN... 
Could anyone give me some suggestions and help? Thanks a lot!

Why not just scrap the TabControl and use a stack of Panels instead?

Is there a Gecko Layout Engine .net Module? I want to have my web browser use the gecko layout engine, but I don't know how I can make that happen other than if there were a .net module for it. Thanks.

there is a tool called "google"
enter the terms:
gecko .net
press the "search" button and .... something wonderful will happen

I have done that and yet I haven't found anything on it, so I was hoping to get a reply from someone that has used something like it, so I can use that too... Your reply was rude, and I don't appreciate it.
|
|
|
|
|
maybe you did it ... but you didn´t read the page ....
a few lines below the "main" article you would have found a reference to geckofx .... and that is what you (probably) need.
to moan about a correct, short info as "rude", will prevent a lot of people to answer you in the future.

Hi, I was wondering if anyone knew if there was a way to output bytes through a comm port in a HEX format rather than ASCII using the SerialPort control or any other method.
Thanks,
|
|
|
|
|
A serial port can transmit arbitrary byte values (i.e. binary data) as well as textual data.
The former is supported by methods such as SerialPort.Read() and Write(), the latter by ReadChar(), ReadLine() and more.
Not sure what you mean by "HEX format". Is it just binary data? use Read/Write! Is it text according to some specific format (such as Intel Hex, Motorola S-records, whatever), build your string and send it, or receive your string and decode it.

I have an application "app1" which create a UDP socket with port no. 6677.This app broadcast a data packet.
I hav another application "app2" which also create UDP socke which always listen 6677.Whenever the data packet comes it do certain operations.
Now problem is , when I run these to apps on different machines in the network, app2 detects the data packet.But when I run both the applications on the same machine,app2 never detects the data packet.
What may e the problem???
UDP socket related code in app2 is pasted here....
wsClientRecieve.RemotePort = 6677
wsClientRecieve.RemoteHost = "127.0.0.1"
wsClientRecieve.LocalPort = 6677
wsClientRecieve.Bind 6677
Thanks in adv..

I don't know the answer to your problem, however, I always start by asking myself: would I be the only one with such a problem? when not, I try google[^]. There sure are some interesting hits, such as this one[^]. Good hunting!

Damn, i thought this was the start of a Joke and was waiting for the punchline.

There once were two UDP sockets entering a bar. The bar tender says... I don't know any socket jokes, sorry.
|
|

The first one said:
- Hey, man, yesterday I asked Mary to marry me.
- And what did she say?
- Errr... I don't even know if she was listening...
Yep, this is UDP.

That is why SMS is more suited for the occasion I guess.

Ok, I have done something similar and got it working
I "think" the answer is that your localport on the "client" app should be 0 to allow it to use another port to connect from, I use .connect rather than .bind, I don't know enough to say whether this is because I am using vb6
basically only one process can create/bind port 6677 on a given PC and other processes have to connect to it. If you are indeed trying to create the socket in both processes the second create should fail
