Make Image Combo Validation?

Jun 10, 2010

I want to VALIDATE Image Combo control just like the one that is in CommonDialog control. Now I have to choices:1. Put validation routine in Click Event, it works fine if I only use mouse, but if I use keys (Arrorw, PgDn-PgUp, Home-End, etc) Click Event is invoked.2. Put validation routine in Validate Event, perfect; but I will work until when focus is moved to other control.How CommonDialog Image Combo does work? I can open it with mouse click or with F4, then I can move across options with mouse or keys and, when I click a choice or press Enter is when validate routine is invoked.

ComboBox Problem - Combo Box Won't Drop Down After Cancelling Validation?

Feb 24, 2012

I've found some unexpected behaviour in my ComboBox, which I'm hoping someone can help me with. If focus is lost by pressing the Return key on a form which has AcceptButton set, then after handling the Validating event and cancelling the validation,the ComboBox will not drop down any more. When you click on the drop-down arrow, the list drops down momentarilly then goes away again To reproduce this, create a new VB.NET Windows Forms application. Drop a Combo Box and a Button onto the default form, then add the following code:[code]....

Run this application, click on the Combo Box, enter some random text (e.g. "asdf"), then press Return. After this, click on the drop-down arrow on the Combo Box.I'm using Visual Basic 2010 Express on Windows 7 Home Premium.

I have dragged across the details of a table from the data sources onto a form. So VS2008 automatically generate the BindingNavigator, DataAdapter,Dataset, ...etc. On the form I hv also placed an errorProvider and listbox, which is bound to the bindingsource. So as user clicks on the items of the listbox, the values of the textboxes changes accordingly. My question is how do I validate the values in the textboxes.

VS 2010 - Image Resources - Make A Picture Box And Import An Image

Sep 17, 2010

I made a picture box and imported an image named Title.jpg. Later I made adjustments to the picture and imported it again without deleting the original(mistake). The new one had the name automatically changed to Title1.jpg. So I deleted the original image from resources and renamed Title1.jpg back to Title.jpg.

Now I got two problems. First, only Title.jpg is on the solution explorer, but Title1.jpg(along with Title.jpg) still pops up on the resource list when I click on Image property of the picture box. There's only the name and no picture, and I don't see a delete option. How do I get rid of it? Second, even though I changed the image to the new Title.jpg in the picture box, the old one is displayed when running the app. What's up with that?

Make The User To Be Able To Select A State From A Combo Box?

Feb 8, 2009

I'm setting up a program where I would like the user to be able to select a state from a combo box. I can not figure out how to allow to select the abbreviation from the drop down list and also allow them to type a letter and it will select the state from the state or just allow them to type the full abbreviation that would match what is already in the list. It is supposed to be in the drop down list style. I would also like to confirm that the user has chosen a state before allowing them to click a submit button but I'm not sure how to go about confirming it.
