Apr 27, 2010I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:

Dim depot_refnbr As Integer

What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

Nov 29, 2011Visual Basic 2010 Express: I have a form with a combobox that is populated with the names of locations from a datagrid which in turn was imported at run-time (Form_Load) from an Excel database. The Excel database (and the datagrid) also stores the information for addresses and phone numbers for their respective locations.
What I would like to do is have the phone number and address text boxes automatically be updated with the proper corresponding data when the user selects a location from the combobox. Whether the text boxes are updated from the datagrid or Excel database is not a concern; I'm mainly looking for whichever way is simpler.

Calendar Selection Output In Listbox
Jan 16, 2009I've been making a scheduling program using the calendar object.I can manage to select any date with a single click with a message box pop up entering a memo for the date selected. After pressing ok, the memo is displayed in a list box, with date.
1.Unfortunately the date is being displayed twice - perhaps because i used .selectedrange in the handler ? i would like it to be listed only once
2. the memo comes up on a separate line, ideally id like it to be displayed on the same line as the date.i tried ListBox1.Items.Add(whendate, memo) but it cant compile, so ive had to put each line in seperately
3. I would like to mark the sundays and national holidays in red color (the calendar is only set for a year so i dont mind doing them by hand, however the only tool i can find in the Monthcalendar1 properties is MonthlyBoldedDates, and no color assignment [code]

View 39 RepliesStoring Information To A Listbox Selection?
Dec 21, 2011I am creating a program with multiple Forms designed to track multiple projects.The first form is designed to setup new projects and obtain previous projects, from there the other forms open to be filled in with information.For new projects the next forms open blank but I then need these later forms to be tied to this project name so that it can be selected from a combobox and the information will be already populated.tieing the information on the later forms to the projects populated in the combobox so that it appears when a specific project is selected.Is this able to be done without creating databases?
As an example, say I create a new project then a new form opens and I add some information to a textbox.I would then like to be able to save the information so that the project name moves to the combobox on the first form (I can handle this) and the information input in to the textbox is tied to the project name so that when the program is reopened and the project name is selected the second form opens with the textbox populated.
