I have a combo box on few of my vb.net 2010 programs. The end users that use my program have touch screens and they have a hard time making selections on the combo box. I have an Android cell phone and when ever there is a combo box it will open another screen and making the selection is a breeze.

I've got some code like the following. I want it so that when I chose an item in 'select 1' it changes the in the second combo box but I'm not sure of the best way to go about it. Does it have to be AJax or can it be done with just Javascript?

I'm new to VB.NET and looking for some help with combo boxes. I was wondering if it is possible to link 2 combo boxes to each other based on user selection? [code]If the user selects Dept Name "Bakery" from the first combo box the second combo box should fill with the appropriate Section Name i.e. "Bread", "Cakes" etc.I am using VS2008 and the DB is SQL Server 2008. Both combo boxes are currently bound to the above Tables and displaying all Dept and Section Names.
View 2 RepliesThe combobox is bound via binding source to a table. How can I display the list of look up options while having the first option say [None} and if selected, clears the value from the list.

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.
View 7 RepliesI am currently stuck in one part of my application. I have two combo boxes that i am having the users select from.

As the title suggests I have a ComboBox and 2 listBoxes on a form. I need to fill the left ListBox with items not now asssociated with the ComboBox selection and the ListBox on the right with items already associated with the ComboBox selection. Is it possible to populate the ComboBox and each ListBox using only one query and returning a dataset of ALL the data to do so, or do I need to Populate the ComboBox, then use 2 queries, one for each ListBox?
View 6 Repliesi want user when clicks a button to show a selection around a richtextbox and not inside it selecting the text... what i have right now is this: richtextbox1.focus() that will indeed focus the richtextbox but the problem is, it only selects its text content.

i tried messing with the vb express rectangle stuff but i cant get it to draw over all objects, its actually always displaying below all objects in the forum
EDIT: ive also tried using a tiff picturebox with a drawed empty rectangle on it, but the dreadish thing when put over other objects like textboxes, it simply just displays the color of the form emitting any other objects in between, setting the background color to transparent under web colors had the same problem...

View 1 RepliesI have a ComboBox that is databound to an ObservableCollection of strings. The ComboBox is also editable, so you can either enter in your own value or select one from the list. The issue I'm running into is the index of SelectedItem seems to be the index of the last item you selected when you've entered in your own value in the ComboBox, though it's -1 when you have IsTextSearchEnabled set to true. The problem is, if someone entered their own value and then decide to instead select the item on the ComboBox that had been selected before, the index doesn't change so the SelectionChange event doesn't fire. How could I get an event to fire in this situation?

I'm trying to bullied a simple cheap software to rise money.Any way, I managed to make a serial login form but the problem is I need it to appear only once pear purchase, meaning as soon as you enter it once, it will be saved and the login form wont popup when the program gets started again on the same PC.

I am trying to make it so when a user logs in the code can tell, if they are a user or not, if they are a user, then if they are a teacher or not. I have SQL in there to identify if the person is a user or not, but it won't bring up an error message if they aren't. And if both the users logging in are not teachers they are still able to view a screen they are not meant to.

making a screen recorder. make it take a screenshot 15-30 times a second, and for each shot there will be a text file that will say the location of the cursor when the shot was taken and what the cursor was, like loading or whatever. Then when the user presses save, it will take all the shots, import the cursor in each one and then create an AVI using each of the frames that were initially shot. Another better way would be to take a screenshot with the cursor in it, if thats possible.

View 10 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.

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.

I need to create a login page as part of an assignment. Problem is, I don't have access and I'm not sure which other programs can be used as alternatives.
