Hi, sorry, forgot to mention, its for VB.NET 2005.
How does the mark edit control work? I have looked on MSDN but it doestn really help.
I guess its nothing like excel's input mask!?

MSN has full documentation on how to write input masks for the masked input control. I don't really know, I always write my own code.

A total newbie to Visual Basic and Macros ( as in never touched upon both ), so forgive me if I get anything wrong.
Right now I'm in a project, trying to map an entire enterprise network with Visio. The network has over >10,000 network devices, ie. switches, routers, firewalls, etc. There are some frequent changes to the network topology, therefore by the time I do finish a network diagram, there's a good possiblity of something changing. Also I wish for the diagram to be more "dynamic".
My question is this: Is it possible to use either VB or a macro to test connectivity between each network device? If the connection is live, then the line on the network diagram between the devices would be black, otherwise it will be red. One condition is that I would strongly prefer not to log on to any devices. I don't want the actual code as I would like to learn this myself. I'm just curious as to if something like this is possible.
Thanks for any info.

You can probably shell out to TRACERT, if you don't have a COM component to test for you, and parse the repsonses you get back from it. You could probably do some work testing certain routes if you use the -J switch to give TRACERT a list of routers to pass the test packet through.

Hi everyone:
Is there a way that I can make the icons on the listview bigger? I tried setting them to large icon, but, they still seemed quite small. I really just want a list of pictures with no text, that would be perfect.
Regards,
James

I'm assuming by "setting them to large icon" you changed the View property of the listview? Is that right?
How big are the icons you are using? 16x16? If that's the case, you may have to use bigger icons than 16x16.

there r many links on the internet
vb.net express edition is absolutely free.
use bittorrent client to download it.. it is the safest bet
|
|
|
|
|
can you please geive me exact link for downloading vb.net and asp.net for free
|
|
|
|

The only place you're going to find VB6 is if you buy it off EBay. It hasn't been available for retail for about 5 years now.
ASP.NET can be had, along side the VB.NET Express Edition, as Visual Web Developer Express Edition. Both of which you can find here[^].

heres a snippet from a prog a wrote in vb6
Public Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long
Public Const CB_ERR = (-1)
Public Const CB_FINDSTRING = &H14C
Private Sub Combo1_Keypress(Keyascii As Integer)
Dim CB As Long
Dim Findstring As String
If Keyascii <32 Or Keyascii > 127 Then Exit Sub
If Combo1.Sellength = 0 Then
Findstring = Combo1.Text & Chr$(Keyascii)
Else
Findstring = Left$(Combo1.Text, Combo1.Selstart) & Chr$(Keyascii)

hello everyone
i have two images of a single finger , stored in byte arrays.
is there anyway i can compare them relatively..i mean is there something that can giv me the relative similarity or difference between the two byte arrays?
|

This will only happen if you either write the code to do the comparison or find a 3rd party library that does what you want. There is nothing in the .NET Framework that will do this for you.

Hello everyone:
I have a quick question about rich text box controls in visual basic. I basically want to change the colour of the text in one of these controls, but I can't see another way to do it then use the "Select" command. This basically highlights text and then you can make whichever changes you want. The problem is of course that this has all sorts of unpredictable behaviors which can't be foreseen, and of course, its outright sloppy. The problem is I see no other way to edit the internal data easily! What's the standard correct way to do this sort of thing?
Regards,
James

Are you trying to change the color of all the text? or just a certain piece?
|

What you have now is about the only method you've got. ...Unless you want to start parsing the RTF string and inserting the formatting codes yourself.

Ah, that's too bad. Yeah, I only want to edit parts of it. Using the select method has such unpredicatable side effects, its a shame there is no provided control to get around that.
Thanks guys,
James

It's a simple implementation of a RichTextBox control. It's not meant to be something like Word. If you wanted more complex functionality, it would require a more complex implementation, like a 3rd party control or something you write yourself.
