I added a Combobox. Unbound mode, added the lines (text) I needed. What I want to do is on certain lines, click the text and it fires off a process.start.

Process.Start("mailto:test@test.com")
How to identify each line to assign a different process start command.
In my program, I would like to make it so that when you press the start button, it does something else INSTEAD of showing the taskbar. How do I modify this code to do that?

I tried putting in start where it says enter, but that didn't work.
I have the following

and as you can see, I am showing users the next available date open to them is determined with the value dteReturnValue.ToShortDateString .. but what I'd like to do is show the user both the start date and the end date, which will always be +7 days from the field in my database.
I have used the command:
For Each Proc as process in process.getprocesses
Combobox1.Items.Add(Proc.MainWindowTitle)
to populate a combo box with the list of current process windows, however for every process that doesnt have a main window title there is a blank space, is there a way that I could tell it to not insert the item if it's mainwindowtitle field is blank?
How can i start The command prompt (cmd.exe) without the window showing or in the taskbar, like "hidden" and pass a parameter onto it.
NOTE: I esnt to know this for a completly LEDGIT reason.

i have a combobox containing countries name and their codes like INDIA:CNT001 then i have a textbox that store the code of country i.e CNT001(fetching from database) Now i want to match that code with the combobox code so that the combobox is set to that item when i click a button. i m using vb.net and sql server as database.
View 5 Repliesmy program downloads into a combobox every item(line) that is in a text file located on a server.
Every line in the text file ends with "a)" or with "g)".
Now I just want to make 3 radio buttons:
- one that will allow the download in the combobox only the item ending with "g)"
- one that will allow the download in the combobox only the item ending with "a)"
- one that will allow the download in the combobox of both (I already know how to do).
How can I do so?
To download the entire list in the combobox I do:
Dim List As String = client.DownloadString("http://mywebsite.com/mytextfile.txt)Dim lines As String() = List.Split(New String() {ControlChars.CrLf}, StringSplitOptions.RemoveEmptyEntries)ComboBox1.Items.Clear()
ComboBox1.Items.AddRange(lines)
I am new to vb.net and I am using visual studio 2010. I have two comboboxes on a form, each combobox is set to DropDownList so that a list of items can show in the combobox, but no text is allowed to be entered.
For combobox A, if user chooses item 1, the list of combobox B should be updated accordingly. I think this is quite common on a lot of applications. But I do not know to implement it. I even do not know the keyword to search for the relevant property or event handler.

I wanted to put a checkedlistbox in a groupbox with just one item showing and in the mouse enter event show more items by making the height of the checkedlistbox bigger. The problem is, if it gets to a certain height, it disapears at the bottom of the groupbox because thats its parent.
Is there a way of it showing beyond the boundaries of the groupbox ?
