I have the following coding which only displays the first character, the problem is the first value can be more than one character and I want to display the first value.TextBox1.Text = TextBox1.Text.Substring(0, 1)I know I could just change the coding to (0, 5) but this is not ideal for me as values with only 1 characters will have 4 spaces.

The remarked area works fine when I'm accessing a specific table. I've successfully inserted the products_model field into the combobox too.

In my program I want to do the same thing, but I'm using MDI forms - for some reason it doesn't work like above. I tried the same as above as appropriate for the new project but it doesn't show the 2nd picture box.
I've used the same method to add items to a listview before but for some reason they're not showing, I even just tried a test:
Dim row As New ListViewItem
row.Text = "test"
row.SubItems.Add("test")
lstvwHistory.Items.Add(row)
in the load and that doesn't show up.Here is what I am trying:
gameDate = HistoryDS.Tables(0).Rows(0).Item("gameDate")
frmGameHistory.NewGroup(gameDate.ToShortDateString)
For Each row As DataRow In HistoryDS.Tables(0).Rows
[code]....
I walked through the code having a message box pop up every time an item was added with the count and it goes up as it should, nothing throws an error, and the item has all the correct parameters. I commented out the making a new group and just plain add the items and it still didn't show. I tried the lstView in all the kinds of views (detail, small icon, etc.)

I've created a form that plays some internet radio. The thing is the user wants an extra form for volume control that is docked to the side of the main form. This is no problem, i've made that, but im having some trouble making this form shown at the same time as the main form.In short what i want is that when you set focus on form1, form2 should also get in the foreground. Not focused, it should just follow form1
View 6 RepliesI'm trying to create a program that will look at a website and check it for updates, similar to an RSS feed. It then will show a dialog (Form2) that will inform the user that there is an update.Form1 is used as the configuration form and is able to be shown via a notify icon in the system tray, which is on Form1.Originally I would have Form1 hidden via Me.Hide() and then run a timer which would check for the updates and call Form2.ShowDialog() when there's an update, I found out however, that if Form1 is hidden, the dialog will not show.
Next I tried not Hiding the form, but instead setting its ShowinTaskbar property to False. At this point the program functions correctly, however when I minimize Form1 it sits in a shrunken window near the task bar... Is there any way to completely hide Form1 (when minimized), and allow Form2 to be shown as a dialog?
Is there a .Net control I can use to display a web page from a vb.Net windows forms application?
I am writing an app that will produce a slide show from a specified directory. The idea is it will ideally include Images, Video clips (via Windows Media), URL's (held in a text file), PDF documents and power point presentations.
Images and media clips aren't an issue. At present I am looking at displaying specified web pages. I am aware that I can use
System.Diagnostics.Process.Start("http://webinta/Pages/Home.htm"
to open a browser window, but I want control of that as after a specified amount of time it needs to close so I can display the next image (media clip, url etc).
I've been trying to work out away off using a drop down box to hide and show different components, on top of one another, within panels using this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If ComboBox1.Text = "Panel 2" Then
Panel1.Visible = False
[code]....
However this only works as wanted when the panels are separate from one another (one above, one below) but I want them to be on top of each other so I can switch between them. Essentially I want two forms within a form.Second question; I have an equation I wish to implement in my code (N = N0*e^-a*b) does vb have a way of calculating exponentials and logs? (Ie: log(a/b))
I added a new application recently and I find there is no Configuration Manager. I went to Tools-->Settings and checked Expert Settings, but Configuration Manager does not show up in the Build Menu. It only shows Build Project and Publish Project. I also tried to add Configuration Manager to the tool bar - it was added, but it is grayed out.
I'm trying to get the compiler Configuration Manager to show up. By the way, all of my 8 other VB 2010 Express projects have a Configuration Manager option in the build menu. However, none of those 8 projects were started as a new application in VB2010 - they were all conversions of old VB6 applications (first converted with VB2008, and then with VB2010).
