View 1 RepliesI have inherited some code from an external contractor that I have to modify. Firstly, he uses a strongly typed dataset to retrieve some data from an SQL database and then uses that data to populate a listbox. I have decided to use a dropdown list (as the user can only ever select one value at a time).This is the code that populates the DropDownList
Private Sub FillUserComputer(ByVal userId As String)
Try
TraceDebug("Begin FillUserComputer"[code]....
This works well for the first two entries in the DropDownList. However, whenever I select one of the other options and click the Send Request button it "jumps back" to the 2nd entry in the list and sends that data instead, completely ignoring the option I selected.I think I have narrowed down the problem to the fact that the DataValue for the second entry in the list is a Null value.

Dim sel As String
For i=0 To count-1
sel=Me.ListBox1.Items.item(i).ToString
MsgBox(sel)
Next i

View 5 RepliesI want to retrieve the selected items in a listbox, save them to a collection, and then use that collection later. I thought that was simple enough, but when I clear the selected items in the listbox, my collections (items, indices) change. I found this out by stepping through the code.
Basically what I'm wanting to do is move items in the listbox up or down (up in this case), and still keep them selected.

I have three tables in SQL server which I would like to show and access on a form. Table 1 contains account data, address, contact details etc. Table two contains data attached to a Person, tel no , Mobile no, Email etc. Table three contains details on what awards the person holds, i.e. one person can hold several awards.
Therefore I have a one many relationship between the first two tables and a one many relationship between the second two tables. This is set up in SQL
The first two tables are shown on a form, table 1 via a set of text boxes, table 2 via a datagrid control.
I would like the functionality whereby I could select a row in the datagrid showing the persons name and find the Persons_ID number then use that as a filter to a second datagrid view so that only the selected persons awards show in the datagrid.
i want 2 select data from data gridview and want retrive that data into another form in to the textbox ...is it possible ? i 'm doing like this for that

I've pretty much just started in playing with Visual Basic Studio 2010 and have been using this site for lots of answers so thought I'd join up and harass more directlyI've been trying to move items between two lists, one is databound to a bindingsource, the other isn't. I found out that you can't really move items from databound lists, but you can remove from the datasource instead. This works fine until I want to move the item back - it fills a blank line with seemingly no data.
View 6 RepliesI have properly configure the database connection. I wanted to get data from the database to 2 text boxes.
[code]...
1. user writes he's details (textbox1 for username, textbox2 for password)
2. user hits "Login"
3. application tries to retrive data from sql server. (in this case localhost/127.0.0.1)
4. application retrieves data from test/tables/members
5. if the specified account information matches the servers data, it will let you through to the next form. Else, it will give an error that the user/pass is incorrect.
Now look, the table looks like this
[id] | [username] | [password]
1 username password

How to retrieve data from database using Web services on VB?
View 5 RepliesI am retrieving data from a csv/txt file using oledb driver
ConnString = "Provider=Microsoft.Jet.OleDb.4.0; Data Source = " & System.IO.Path.GetDirectoryName(strFileName) & "; Extended Properties = ""Text;HDR=YES;FMT=Delimited"""
strQuery = "SELECT * FROM [" & System.IO.Path.GetFileName(strFileName) & "]"
In the last line I am getting following error if the filename is large
Is not a valid name. Make sure that it does not include invalid characters or punctuation and that it is not too long.
My question -
Is there any limit to filename or the select query or there is some pattern which I need to follow?
