I have 10 Comboboxes in a form. All these combo boxes have databound items which come from the same column in a table in the database (access 07) (Am designing a billing software, and these comboboxes show the items (10 lines of them).All these combos reside in one Groupbox.Now for the strange (scary/funny) part, whenever I change a value of 1 combo, all the other combos change automatically and show the same value as the one that was changed. (strange!).

View 4 RepliesI have an application with a database. I can add, remove and save items but when I want to CHANGE an item and save it, the program gives the following error: Update requires a valid UpdateCommand when passed DataRow collection with modified rows.
I am using "service-based database" from visual basic itself. No acces or something.
I have a DGV I am working on, and I have many columns.
For example I have Columns colcase(Combobox), colreportTime(Time)
the combox shows 4 cases {A,B,C,D}
what I need to do is if the user select "C"
the the colreporttime will show the time of this change unless the old value is C
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?

View 1 RepliesSay I have a table Business in mySQL. The ID in each "business" is a function of title and location. It makes programming much more easy. I also often merge 2 identical businesses, etc. Say one day the title of the business change and I want to change the ID. An operation that I will rarely done. Many other tables point to that business. So what should I do?
Should I create the new ID and then change all relationship that points to the original business to the new ID? Is there a mysql command that'll do this faster? Any sample vb.net code?

View 1 Repliesok, 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.

Using a plugin architecture, i created a Form Class that holds the Mdi Form. it has menustrip, toolstrip and statusstrip.
child forms are created as class and are loaded into the Mdi Form at runtime.
using interface, i was able to execute subs and functions of a child in the Mdi Form and vice versa.
now i need to change property values.. to be exact, i need to change the enabled property of the toolstrip buttons depending on which child form is activated using the form_activated event of the child form.
the problem i now have is how to change the property of the toolstrip item in the Mdi Form.. should i be using interface on this as well by creating subs in the interface and have the Mdi Form implement this interface?
