View 1 RepliesI am developing a program that populates a rich text box and from a click event on a listbox. The data that is being loaded into the rich text box is located in a richtextformat file located on the hard drive. I noticed that when I entered a URL into one of the richtextformat files that it appeared that I was able to click on the text as if it were a link. So I wondered if it was possiable to click on that URL and open a web browser from the loaded richtextformat file? I have read several articles in regards to opening hyperlinks in rich text boxes which can open a web browser with a given URL.

I am really confused! My program doesn't work if I don't have Visual Studio here in my PC. To test it I have uninstalled Visual Studio. But my program doesn't work though Flash Player is present there (I have used Flash animation in the first form).
To be more sure about it I have installed Flash. But it's not working! That means the Flash animation file (.swf) is not making a problem! It needs support from Visual Studio to start. Doesn't it mean that some files are not attached with a setup file as a result it needs Visual Studio to run? Let me tell you how I create a setup file of my program.

I am trying to get my datagridview to display more than one row of data.Every time I call the program it only writes the 1st line of data in the datagridview instead of adding it to a new row.I have been looking on the forums for hours but combined with my inexperience I can not understand it. The following code is in a loop and it reads an xml file each time.The goal is to put the xml data from each file into a new row in the table.Public Sub ReadData(ByVal filename As String, ByVal file As String)Try
DS.ReadXml(filename)
DS.Tables.Add("MyTable")

I've encountered problems with programming a Guitar Hero game (Frets on Fire) because I just started visual basic, but I know a lot still. I am almost done with button pressing and picking and I can easily get the buttons to scroll, but is there a way to program the buttons that scroll along the screen by using a midi file, like in Frets on Fire. I just don't know how I can get the frets (buttons) to correspond with the song without spending hours programming one song by hand.
View 7 RepliesI was just writing a windows application that populates three comboboxes from the same datasource. My datasource is a datatable. The way i populate the comboboxes is by repeating the following code for each of the comboboxes:
'populate 1st combobox
cbx1.DataSource = table
cbx1.DisplayMember = "someColumn"
cbx1.ValueMember = "anotherColumn"
cbx1.SelectedIndex = Indx
[CODE]...
When the application is run, and I select an item from the dropdown list of, say, cbx1, my choice is reflected in cbx2 and cbx3 as well. I find this behaviour strange and will be grateful if anybody could explain what is going on here behind the scenes. On a side note, I've been able to circumvent this problem by modifying my code as shown below, but would still like to have an explanation for this seemingly strange behaviour.
'populate 1st combobox
Dim t1 as datatable = table.Copy
cbx1.DataSource = t1
cbx1.DisplayMember = "someColumn"
cbx1.ValueMember = "anotherColumn"
cbx1.SelectedIndex = Indx

The problem is that this works perfectly if I use the left and right arrows and it also works perfectly if I use the scroll bar's slider SLOWLY.

I have a DataGridView with a panel above it, that contains a group of textboxes above each column. My DataGridView has a horizontal scroll bar. What I want to do is when the DataGridView scrolls horizontally, scroll the panel with textboxes above it, so they stay aligned.I tried handling the DataGridView's scroll event, but I'm not sure what to do with it.
View 1 RepliesI am loading several command buttons into it (one in each grid box). I have the panel set to autoscroll. When TableLayoutPanel is set to AddColumns, all works well. However, I dont want horizontal scroll, I want vertical. When I set TableLayoutPanel to AddRows, a vertical scrollbar will not appear.
View 4 RepliesI'm trying to write some code which parses data and then populates a listbox. I'm using the IPWorks IPPort component which basically does the reading of port 30003. The ipport1_OnDataIn event is where all the action is. I parse the data, which works great.. however when I try and do something simple such as add text to a listbox, I get the dreaded error "Cross-thread operation not valid: Control 'lstListBox1' accessed from a thread other than the thread it was created on".I've googled the error and tried copy and pasting some workarounds but nothing seems to fix the issue.
If anyone can offer help, it would be greatly appreciated. If you could possibly show the code already implemented into mine, it would be even better so I can see how it works. It would make more sense to me. My code is below. The part i'm trying to get working is the lstlistbox1.items.add("Test") in Case "2". This is to just get it working.. I'll be adding listbox items in the other cases as well, and they'll be parsed values instead of "Test". This is just to simplify things at the moment.

How would I leave the vertical scroll position as it is and set the horizontal scroll position all the way left if it isn't already in that position? I've been using Me.AutoScrollPosition and have come up with code that is satisfactory but I haven't been able to always leave the vertical scroll position exactly as it is and just move the horizontal scroll position to the left limit.

I am creating a reporting app that pulls information off of a Sql database and populates the data in a datagridview control (DVG). I am using tab pages (Tabcontrol), and I have about 10 tabs with within the control. What I have done is created a dynamic control that will populate in each tab page once the tab is selected. I am using a split container and in my split container.panel 1 is where all my buttons and search functionality will be. In my split container.panel2 to is where the main DGV control will be. I have got this to function properly, however now I am unable to add anything to my split container.panel1. I would like to add diffrent labels and buttons in the panel1 one without putting another panel on top of the split container.panel1, and also if i do this when I resize my container the panel will just sit there. I am using the selected index changed event to get my split container to show in each of the diffrent tabs

I have a 'DataGrid' usercontrol on my simple little form and I press a button that opens a text file and populates the DataGrid like so,
A B C
1 2 3
3 4 4
3 1 3
Where A, B, and C are my column headers.
I also have a 'ListBox' on the form. What I would like to do is, allow the user to select one, two, or three rows (or all) in the datagrid, and press a button that will move the data from selected rows into my listbox (each row its own string in the list box).
I can populate the datagrib easy enough, but don't know how to access the cell data individually?
