VS 2008 Checking Forms Design?
Aug 3, 2009
I'm very green with VB Express 2008 and am going through the tutorial. I'm skipping over a lot of the exercises as some of it is review for me - I've a fairly solid background in MS Access VBA and forms design there. But I have a simple question on VB Express forms design (I'm not worried about data handling or anything yet).How do I test a form? In my first form on my project, I just press F5 (Start debugging) and it opens just fine. However, I'm playing around with a second form in design mode and can't seem to get it to open to test some of the code (simple msgboxes associated with buttons).
In Access 2003 and earlier, there was a design mode and form view. The Access design mode was the equivalent of the design tab in the VB project, but I can't seem to find the equivalent of the Access form view in VB so that I can open that form. VB F5 only seems to open the first form.BTW, is VS 2008 the correct tag/prefix for this question on VB Express 2008? I see there's a separate tag list - is there an approved list of tags aside from the prefix before the title in the posting screen?

When I open a project created on a PC of XP SP3 and 24" widescreen in another PC of XP SP3 and 22" widescreen, the design of forms including the form size and layout of the components (sizes & locations) changed.

I'm basically putting some validation logic around an undo button on my form and i'd like to check whether any fields on the form have had their values changed so i can ask the question "abandon changes?". This seems like something pretty standard to me but I can not see how to check whether a value has had its contents changed (without recording a before value and comparing it to the after value which for large forms would be quite horrendous to code).
In the language i used to use we used to walk the object tree (so we dont have to specify each object individually like text box, combo box etc) and check any object that have value-changed = yes to indicate the validation was required.

If mixbox.Items.Contains("window") Then
If mixbox.Items.Contains("door") Then
If mixbox.Items.Contains("wheel") Then

how to implement a classic layout design in vb.net (2.0).The application design is the classical toolbar panel at the top and different panels stacked at the bottom. Depending on the button pressed at the top in the toolbar panel a different panel at the bottom will be available.This is thought to have different part of the software available on different panel but with the toolbar panel always available at the top.To implement this I thought:
1) one tablelayout with 2 rows. First row contain a panel with the button (toolbar panel) and adding/removing hte correct panel requested on the bottom row.

I have developed a win form application using vb.net 2.0, mistakenly my vbproj file deleted. Now the issue is that when i open the solution in the design view all my forms ( 170 + ) shown blank. but when i run the application all the controls are properly displayed and application is running fine. Issue is why all forms are shown BLANK in design view , as i cant make any changes to the design now.

I am familer with looping thru controls like so:
[Code]....
Next I have some labels on another form, that due to the design can't be in seperate panels. They are (lblChipColor1 - 6) and (lblChipValue1 - 7). I am trying to populate the color ones from the Array above. I can obviously loop thru the array, but I can't find a decent way to loop thru just the lblChipColorx lables ignoring the lblChipValue1x labels. It would be easy if they were on seperate panels. I tried adding the labels names to an array of type string and of type label, but got nowhere with that. Is there another way to group them, or build const array of label names, that I can work with?

I was wondering if there is any advantage to do everything programmatically instead of using design view to create forms, controls etc. Would there be any difference in size and/or performance after you compile it? So far I've been doing pretty much everything programmatically, specifying all the properties that aren't default for my forms controls but I am starting to wonder is there are any advantages to this, apart from making it easier (sometime) to manage and change the behavior of my controls.

i have a splitter control on tab 2, a grid and a scheduler control on tab 3..looks fine...i save it....close the form...reopen the form, and the controls are all resized and moved around on me....and not for the better.
wierd thing is that when i run the app, the controls are placed properly, but design time is totally f&*ked up.I know this one isn't me. is it the tab control? should i just do toggle buttons at the top and show/hide my own panels? this is just too freaky to deal with. is there an easy work around for this?

i know My.Computer.Network.Ping but as alot of people know, it's glitchy and bugged.
I want something that checks to see if it can connect with something, as simple as it sounds.
I'm experimenting with sockets at the moment, but having trouble so i thought i would come and ask here
What i'm up to:
VB
IP = Net.IPAddress.Parse(getinfo("settings.inf", i & "IP"))
socket = New Net.Sockets.Socket(Net.Sockets.AddressFamily.InterNetwork, Net.Sockets.SocketType.Stream, Net.Sockets.ProtocolType.IP)
[Code].....
However the problem with this it that i pinged 1.1.1.1 and it still connects, ALSO i would like to be able to check a hostname not just an IP to make things more convenient, please help me to find a way to properly check a connection with IP or hostname.
Note: The getinfo function is defined by me

In the following code, a Date variable is declared but not set to anything:
Dim myDate As Date
What's the proper method of checking if the Date variable is "new" and not set to anything?
For example, getting the lowest date value from an array of dates:
Dim dtMostRecent As Date
For i As Intger = 0 To myDateArray.Count - 1
If myDateArray(i) < dtMostRecent Then dtMostRecent = myDateArray(i)
Next
In the code above, I need a way to check first if dtMostRecent is unassigned, in which case just give it the first value, after which it can be compared with subsequent values. How to check if a Date variable is unassigned.

I have 22 text boxes that have to be checked to see if the value has changed. I am using the TextChanged Event handler to do this thus:
Private Sub TextStringChanged(ByVal sender As System.Object, ByVal e As System.EventArgs)
DataChanged = True
RemoveHandler ........
[code]....
The Handler would be added after the data had been loaded. The question is:Is there another way of checking for text changes without having to add and remove 22 handlers.
