In vb2010 I am trying to create a small program, I have a textbox and a combobox.
The combobox items are dynamically loaded.
The msaccess database has 3 columns (excl id), groupname, realname, emailaddress.
When I select in the combobox an item, records who has the same name in the groupname column, should select all the email addresses (seperated by a ";") and put them into the textbox.
For example:
When selected Group1 in the combobox.
1: Group1, Rick, rick @ rick.com
2: Group2, David, david @ david.com
3: Group1, Louise, louise @ louise.com
In this case the emailaddresses of records 1 and 3 should be into the textbox:rick @ rick.com; louise @ louise.com
Those who are looking for an example like this, might find it useful (or not). I know i was looking for one like this for over a week. Ok now, to make this codes work properly, you have to make a Database in Ms Access (I used MS Access 2007) . Create a table of two Columns, one name Debit and one name Credit. Both of the Columns Data Types must be Long Integers or you might get some conversion errors at run time. Now save the database in Access 2000-2003 Database format. And last of all, put the database in your projects DebugBin directory to avoid the database Connection Errors.
I want to compress an ms access database using vb.net. If the database is open this fails. How can I close the database, compress it, then reopen the database using vb.net code to accomplish this. I've already successfully written the code for compression, but I can't find anything on closing the database while leaving ms access open.
In my window application i have taken one combobox field with its collection as "amc", "war" etc. Now in my datagridview this combobox column is display as Textbox column, i want to change it to combobox with the above collection "amc","war". I have retreiving the result in datagrid through sql query, hence in datagrid edit column section we doesnot have that part to change to Combobox column.

I'm using VB 2010.I want a 2-column listbox control where the program fills the first column and the user can fill the second column. For example: The first column lists data fields (age, weight, eye color) and the second column allows the user to enter a query criteria (>65, =150, 'blue') which control I can use? Or maybe I need to create a 3-column grid?
In my form I have a text box for user to enter the number of column and row. And I also have a text box to enter the first X value and Y value. Now what I want to do is if user enter 2 for row and 10 for column then now I will have two rows with 10 column. The X value is for column and Y value is for row.
It will look like this ********** **********
When the user enter the first X and Y value. For next X and Y value i must plus the original value with 2.54. So my X1=TextBox1.Text Y1=TextBox2.text this values are input by user.
So X2=TextBox1.text + 2.54 X3=X2 + 2.54. and so onn. Same apply for Y Let say user input are X=100 and Y=100 The value for first * is X= 100 and Y=100 Second *X=102.54 and Y= 100............. and so on For 11th * X=10th *value + 2.54 Y= 100+2.54 and so on The row and column is not same always it depends on user..
