Enable/Disable Combo Box From Another Combo Box?
Feb 7, 2011I have a form with 8 combo boxes and would like to disble certain combo boxes, depending on what was selected in another combo box. The reason is so the user will not have a blank return on a query. The first form I created like this worked great, no issues. This form only allows one combo box (Number_of_Lightheads) to disable any others. Below is the code I have for this Form. why the other combo boxes will not disable the ones that are called out in the code?

VS 2010 : Coding A Save Button And Combo From A Form To Work With A Access DB?
Feb 23, 2011I am a bit stuck with coding my save button and combobox.My entire form is ready, database is linked.All fields from DB are linked to their textboxes on the form.But i just ran into a big wall which i cant seem to break down.My save button, which is used to save the content from all the textboxes on the form to the access database refuses to work.The other this is, i want to use a combobox on my form to view the already saved entries in the access database.I think a combobox works for that, but i am not exactly sure how to pull that one off.

May 1, 2010I have two comboboxes on my form and both are bound to the same datatable. The problem is that each time a value is selected from one combobox, the value in the other combobox changes to the value selected in the former. Is there anyway to disable this behaviour?Only performance counts!
View 2 RepliesVS 2010 Disable Ctrl + U Key Combo?
Oct 26, 2011I've read many posts about disabling Alt+Ctrl+Del and Ctrl+Tab, etc. I'm not looking to do that. What I'm trying to do is create an app which will be hidden, and then need to be unhidden from "anywhere." For example, if I have an Excel spreadsheet open, I want to be able to use a combo like Ctrl+U to Unhide my program, but I do NOT want it to underline the text in the cell I'm currently in (which Excel will normally do). I don't want to worry about disabling or changing shortcut combinations for Excel, Word, etc.

View 2 RepliesCombo Box - Disable SelectedIndex Changed Event During Form Load
Apr 26, 2010I 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.

VS 2008 Disable Text Boxes Until Combo Box Choice Is Made?
May 28, 2009I currently have my cute little first program made... I'm just stepping into the water with this programming thing. I made a program where you can select a shape from a drop-down list and then input some values and click a button and get the area of the shape. I have it working so that when a certain shape is chosen, certain fields are disabled, such as when you pick "circle" from the combo box, the "length", "width", and "number of sides" text boxes are disabled but the "radius" text box is enabled, thus allowing you to enter the radius and find the area. I want to make it so that when you first load the program, all of the text boxes for the length, width, number of sides and radius are disabled until you select a shape from the list. Currently I'm using

Unable To Disable Textbox?
Jul 20, 2010I'm currently working on "transferring" my vb6 application to vb.net. I'm doing a complete rebuild from the ground up - which allows me to address issues that have arisen over the life of my vb6 application and I'm also learning .net as I work. My primary concern though, is that on one of my forms I display all the information about a customer (Name, Address, Notes, Phone Number, Assigned Salesman, etc.) in VB6, I put all the textboxes in a frame and disabled the frame so they boxes looked "normal", meaning there were still white with black text. In .net, if I add the textboxes to a

View 5 Replies.net - Disable A Button Based On Three Textbox Fields?
Dec 13, 2010I'm quite new to VB.net (and VS 2008), so I'm afraid my question might be basic, but I'm not sure how to solve it.I have a winform with three textbox fields and a button. All textbox fields must be filled before the user can click the button to continue. To this end I would like to disable the button as long as there is at least one empty textbox.
If I had only one textbox field, it would be easy for me to do. In the Textbox1_Leave event I would check if Textbox1.Text is not empty and if so, set Button1.Enabled = True.But what should I do if I have three textboxes? Have three event handlers, one for each textbox? Or is there a way I'm not familiar with?
