View 1 RepliesI have a few combo boxes that need to be loaded up once and displayed multiple times (whenever the main form is opened) The reason for this is because it's taking about 10 seconds for the form to load each time it's opened due to unnecessary re-querying.
Here is an example of what I have as a combo box source and what I've done.
I've put the query, connection, etc... in a module and call it on the login form - i don't get any errors but the data does not load into the combos.
'In Module
sql = "SELECT DIR_ID, DIR_NM FROM LTC_FBS_DIR ORDER BY DIR_NM ASC"

I have a combo box on a form. I have a SelectedIndexChanged event, that displays a message box when the combo box has another item from it selected. This works fine. However when the form is loaded, I initially want to set the current drop down box item from the database, then AFTER I have set the current value, I want this event to work. Problem is from the get go when the form loads it asks me the question as its being changed from 'no data' to then be populated with a bunch of data and an item selected.

I'm using Microsoft Visual Studio 2005 professional edition and I was wondering how to put files with a certain extension such as .txt from the applications current directory into a combo box in the application itself.
I have no idea how to do this or even if it's possible.Actually if no one knows I would like to ask how to get a button to open up one of those file browsers to look for a certain file and then assign a variable to the path of the file selected.
I'm trying to get the text portion of the combo box when a value is selected. I can get the selected value, but if I look at the selectedText or Text property the value is "".
I'm using the following
Private Sub cboVendorSearch_SelectionChangeCommitted(ByVal sender As Object, ByVal e As System.EventArgs) Handles cboVendorSearch.SelectionChangeCommitted
clsVendor.ID = Me.cboVendorSearch.SelectedValue

I am using a Combo box control to select from a list of Databases, and when one entry is selected I display a listbox of certain objects in the database.Other controls are then used to filter the list based on either name or content.Now, I want to know how to Re-load the original list based on the current combo box selection by using a 'Reload' button.In the button code I am setting focus back to the combo box, but whatever I try I cannot make the list refresh again. I've tried Select, SelectedItem, Text and Find methods but nothing works.How do I reload the listbox without having to manually use the drop-down and select the same item again?
View 7 RepliesI'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.

ok, got a question here, two really. first i'll ask the hard one, as i think i have my other one out of the way so i'll save it for later but i made a program where a user enters in dimensions in several text boxes in inches. there are radio boxes that the user decides what thickness of wood they would like to use. what i'd like to do is add metric into the program and use two combo boxes. one combo box drops down and you can select inches, centimeters, or millimeters. the other one drops down to choose the thickness of the wood.ok now here's my question. say i pick inches in the first combo box, i'd like the second one to display only the thickness of the wood in inches, no metric. if i pick centimeters, i'd like the second combo box to display the thickness of the wood in only centimeters, no millimeters or inches. and the same goes for millimeters.i also have the program on a timer that runs at 100 milliseconds so the user can quickly see the differences in dimensions they put in instead of having to hit the calculate button over and over and over (not sure if that really matters or not, had a couple issues with the boxes earlier but don't think it was timer related now)but is this possible? basically just looking for the kinds of drop boxes that you see on a page like autotrader.com where you select dodge, and then only the dodge cars are listed, select chevy and the chevy cars are listed, etc.
