On the update, it needs to change the textbox text back (as it's bound) to the value of the combobox text (unless the combobox is of type other, in which case it'll simply remain as the textbox value). Under this condition, if the textbox's text is misspelled and then corrected, or if a different value is picked from the combobox, it needs to change to the condition of where the textbox text is found in the combobox list. If the type is not found in the combobox's list, I want to have the combobox to display "Other", have the bound textbox remain as it is with the type in it.

What I want to do is check to see if the value of the bound textbox of Type is one of the types in the Combo box, if it is I want to have the textbox be blank, the combobox's type to be selected. The main table that has everything bound has a field called "Type" that has user entered data, and several hundreds of records that have variations of the spellings or type, so I have made a seperate table that contains a list of the 8 or so main "Type"s, including one for Other which is not found in the Type field for the main table. I have a sub-form where all the data is bound from one table, and have added a combobox to this sub-form in which it is not bound, but gets it's data from a seperate table. I'd know how to do this in VB.Net, but unfortunately I'm using VBA. The reader gives access to the ' results.ĭim reader As OleDbDataReader = cmd.ExecuteReader()ĭim schema As DataTable = reader.GetSchemaTable()įor Each schema_row As DataRow In schema.RowsĭataTypes.Add(schema_row.Field(Of Console.WriteLine(schema_row.Field(Of ' Type)("DataType").I'm having some problems finding the proper VBA syntax for checking to see if the text in a textbox is contained in a combobox. ' Open the connection and execute the command. ' Make a command object to represent the command.Ĭmd.CommandText = "SELECT TOP 1 * FROM " & table_name Private Sub PrepareForm(ByVal db_name As String, ByVal _ ' Make a list of the table's field names and prepare the ' first ComboBox.

#Vb net 2010 how to show text in combobox code#
The following code executes when the form loads. For example, if the user selects the Title field from the first combo box, the >= operator from the second, and enters R in the first text box, the program searches for records where the Title field has value >= R. The user can use these controls to determine how the program queries the database. The middle column holds operators such as =, =. The left column contains combo boxes holding the names of the fields in a database table. The top of this program holds three columns of controls. NET.ĭatabase, DataGridView, DataTable, DataAdapter, OleDbDataAdapter, data adapter, bind, DataSet, DataTable, Visual Basic. This example shows how to use combo boxes and text boxes to let the user pick search criteria for a database query in Visual Basic. Use combo boxes and text boxes to let the user pick search criteria for a database query in Visual Basic.
