I am doing a lab where you have to connect to the database using the Database Configuration Wizard in Visual Basic (Visual Studio 2008). The database connection is there since the form will display the records.The problem is the user is supposed to be able to click on the combobox arrow to select a stock rating (high, low, etc) and then the listbox will display only the stocks with that rating. I thought this would work but nothing is showing up in the listbox.
' strSql is a SQL statement which selects all the fields from the Team database.
Dim strSql As String = "SELECT * FROM Stocks"
'strPath provides the database type and path of the Team database[code]...

so listbox.Items. Add(StringRandom) but it should be displayed as A, B, C
not
A
B

View 7 RepliesThe program must display numbers 0 to the highest number entered into one of the textboxes which are even division of bigger number by smallest number.The program isn't quiet done, but I have the rest of it figured out.The problem is that for some reason the program won't change the label status text and display numbers in the listbox if number1 is negative and number2 is positive. But if number2 is -10 and number2 is 3 it works. Also it ignores any other If statements I made.

I've set my DisplayMember property of the listbox to the property I want yet when I add the objects to my listbox it "fails" and instead uses the .ToString of the entire object which doesn't return what I want.

the DisplayMember only works if your listbox has a datasource. Well I'm not using a DataSource, like that guy I'm just using .Add. So how do I get DisplayMember to work without using a DataSource?Also I tried putting all of the objects (their simple item structures) into a List Of and then set that list as the DataSource to the ListBox and it actually added all of the objects to the listbox however the DisplayMember still didn't work and all I got where the results of Object.ToString().

View 5 RepliesI have a SQL table that contains 2 columns - report names and report category. In my application, I have one listbox that displays these report names. I have several categories for the different reports I have. Is there a way for me to display reports belonging to a particular category in one listbox and then have another listbox for another category? This way, depending on user login, I can selectively disable certain reports from certain users. I was hoping that this can be done during form load and not having to click a button to do any BindingSource.Filter method(). I have command buttons that let me search for a particular report based on user input of either the report name or category using the BindingSource.Filter method(). For my Listbox, I have the DataSource & DisplayMember properties set to Report_NamesBindingSource and ReportName. For one of my tests, I took out these two properties and wrote the ff code -
lstBxReportName.DataSource = "Report_NamesBindingSource"
lstBxReportName.Items.Add(Me.Report_NamesBindingSource.Filter = "ReportCategory = Cath")
lstBxReportName.DisplayMember = "ReportName"
hoping to set these properties programmatically and hopefully filter the dataset based on category but I get an error msg on the first line of code. -[QUOTE]Complex DataBinding accepts as a data source either an IList or an IListSource.[/QUOTE]Obviously, my code is wrong. When I comment out the first line and run it in debug, there is nothing in BindingSource.Filter when I hover my mouse pointer over the second line. So my listbox is empty when I run the program.The filter code below works fine for one listbox but I'd like to have different listboxes for report categories I have.- Me.Report_NamesBindingSource.Filter = "ReportCategory = 'Cath'"But how can I assign this type of filter to a particular listbox.
I am using vs2005 with access database.In that program I have a small problem.I have joined 2 tables and get 2 column with a parametrized query.The query will work efficiently on a access database.When applying thru vs environment it doesn't do anything.I think that is a small error in my code displaying the listbox.[code]
View 1 RepliesI have created an access database which i want to search with vb.net, I tried a few thing but it didnt work as desired.
Firstly the program is suppose to display items in the database base on the criteria selected by the user. what i've succefssfully done so far is I've added a datagrid 2 combobox, 1 (searchcbo) with the columns in the database and the other (searchcbo1) will autoload the items under the column selected in and a button (searchbtn) but i have no clue of the code to put in the button. i also tried the fill method but that didnt work as i wanted to. ultimately i want a combobox with the list of columns and a textbox to enter criteria and of course a search button.
The searchbtn should act as the "WHERE" sql command, e.g. SELECT EmployeeNumber, Firstname, LastName, Phone, Location....etc FROM CallLog WHERE searchcbo.text = searchcbo1.text And display the results in the datagrid.

I'm trying to pull all records and fields from a MS Access table. My fields are: numOne, operator, numTwo and result. I'd like to display those fields in a listbox as the following output: 1(numOne) +-/*(operator) 2(numTwo) = 3(result) or simply 1 + 2 = 3. I was able to get some coding going. The problem that I have is that I'm not finding a way to add the fields on the same line, since I can find the right syntax to have all fields added together.
