I want to pull data from database and populate an array. Field one: A short name to call the second. Field tow: A connection string to a database.
EG: Cstr=Connstr("OrDB")
The known name of OrDB would result in a string assigned to the variable Cstr that could be a connection string to an oracle database.

After reading the file, I want to load the NameId, the ColourId and the Text into a multidimensional array. Anything I have found about loading into an array shows text being separated by small delimiters like commas, but this I cannot do because I need to use this format. What I am wanting to do is load all of the NameId's into a listbox and when a certain NameId is selected, it will bring up the Text in a TextBox and the Colour value in a ComboBox.
I have VS 2005 installed in my sytem fyi.We have two databases, say source database and destination database. The databases is in Oracle.

Using windows forms through VB .NET, is it possible to create a exe and schedule the exe on nightly basis to pull the data from source to destination.how to do this as for manipulation of data, there is no intermediate database for us?
View 1 RepliesI'm having a problem to pull data from MS Access to my combobox. I know how to search one data using another data (e.g: using IC num to search name) but this time I just want to pull the data (e.g: name) that has several rows to my combobox. I think the method is the same but don't know where to change it.

I have a VB 2010 program with a single-table Access Database.I have selected the option to copy the Access Database to the output directory.When doing so, the program copies the original database to the inDebug folder.I want the original (NOT the copy) to be modified when the program is being tested.Also, when I attempted to publish the program and run it to test, I got an error which was sourced to be a temporary file (which was the database) that was missing.I think this is a reaction from the "Copy Always" option.

I need to populate data (Patient ID and name) from a MS Access Database table (PetientInfo) into a listbox depending on date (Datetimepicker). The listbox item will change upon date changed.
When I select a item from listbox the details of the patient will show to the textboxes.
I 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.
