I am using a combobox in VB .net to show customer's name. They also can type new names if they wish. Can I somehow save these new names in my sql database dynamically?
What I mean is if the name is new and does not exist in my database, can it be automatically saved to the database?
My combobox is bound to my name table.
I am not sure how I could achieve this: allow the user to select a value (string) from the dropdown list of a ComboBox and display another value in the editable text. The user can modify this displayed value as well. In VB6 I had a combobox where the list property contained a two dimensional array. When the user selected a value from the dropdown list, the displayed value was set using the second dimension of the array. Something like this:

I was just wondering if this is possible. I have a site that admins use to add products to our database. The database is in SQL Server 2008 and I use Visual Studio 2010 using VB.net and was hoping that upon addition of a new product, it would automatically generate a folder assigned to that product's ID.I haven't found anything online that would suggest that this is a possibility, but it would make it a lot easier for me. As of right now, I have to remember to create a folder in the X: drive for each product that has been added. We are up to 645 products now,

I am trying to go to the next item in a listbox automatically when a song finishes in my media player. I've done this in my other player, but unfortunately have lost the source code.
I have this code
If MediaPlayer1.playState = WMPLib.WMPPlayState.wmppsStopped Then
ListBox1.SelectedItem = Me.ListBox1.SelectedItem + 1
MediaPlayer1.Ctlcontrols.play()
End If
But everywhere I put it, it just doesn't work.
How can I get my textbox to automatically insert 'http://' before the url? It is an address bar in my web browser.
It needs to check if http:// is already there, and if it isn't, add it before the url.
when i input data to a textbox1 and then i press enter using keyboard, then another description will appear in textbox2. For example, i have to key in a company's code: A001 into textbox1, after i press Enter using keyboard, the company's full name will appear in textbox2.
View 4 RepliesI need to automate the installation of some Antivirus applications. I can easily do it by utilizing the Process Class, but I also needed to know if there was a way to automatically input the serial key.
I thought I remember someone mentioning a property or something that could be used for that, but I can't remember what it was or who said it.
When adding a new item (class, control, etc) in C# it will automatically add a namespace to the file depending on the location in the project.
Is this also available for VB.NET?
The code 'Namespace DataClasses.AX' and 'End Namespace' would be generated.
Namespace DataClasses.AX

When my application starts, it scans the computers registry for COM ports and adds them in the combo box. The combo box first index is just a blank, and the second is COM1, COM2,...COMn. What I want to do is by default, I want my program to select the first COM port in the combo box, so in this case, COM1.
I know I have to use the PORTNAME property of the serial object, but not sure how I would set that equal to the 2nd index of the combo box.
I have a textbox that represents a primary key in my database. Because the values are nvarchars I can't automatically increment for a new insert. Instead I have to read a value from a drop-down, perform some magic, and create a new incremented value for the new insert.
I've written codebehind that does all this when the drop-down is selected. It works, in that it puts correct values into the textbox. However when I try to insert, I get an error that that field cannot be null.
I'm pretty sure it's because I'm doing this in the codebehind : myTextBox.text = newValue
which wipes out the binding the textbox should have : Text='<%# Bind("UniqueName")
How can I calculate the needed value for this field programmatically and set it back to the screen so the user can see it (and possibly override it) and still keep the databinding intact so I can create the new record?
I'm trying to automatically insert commas after ever email in textbox1.text after the user imports a list of emails.Something like ..I want this to automatically occur after the user either drags n drops the emails into the textbox or copy n paste the emails into the textbox so that the user doesn't have to manually insert commas.
View 4 RepliesI'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:
.cbbCOMPorts.SelectedItem(1) =
True
While this compiles, the computer does not like this at run-time. It throws an exception out:
"Object variable or With block variable not set."
