VS 2008 Disable Text Boxes Until Combo Box Choice Is Made?

May 28, 2009

I 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

[Code]...

This works for disabling the correct boxes when something is selected, but I don't know if I'm even on the right path with that first part.

Turn On The Single Instance Application Choice In Visual Studio 2008 Properties?

Dec 22, 2010

I wish to turn on the Single Instance Application choice in Visual Studio 2008 properties. To do so, I must choose "Enable Application Framework". When I do that, my ONLY choice is to choose a Startup Form, not a Startup object. This makes no sense to me. I have a tray application, and I check to see which form I should load, a logon form, or the main form. But since I am forced to choose a startup form, I MUST load the logon or main form to begin with. But I don't want to. I want startup code to determine which one to load first. So then I am playing with making the OTHER form invisible, even if the startup form, but that is a mess.

Choice For Server Applications?

Apr 8, 2009

I am about to start developing my second application in VB2008. The need is that it has to run on a network enviorment, probably under windows nt, the database has to be on the server so everybody uses the same data. The database is suppose to contain a lot of data on many tables, whatīs the ebst way to go? Access, SQL, foxpro dbf? Also what kind of project am I suppose to start? a windows app? or some kind of .net app.? I am sorry if I am saying dumb stuff itīs just that I am a rookie. Have in mind that after I build the application, many users have to have access to it from different computers and I also want the database to be availbale for a future website with forms and queries and stuff taken from the same database, is ASP the best choice for that purppose?

Display Choice Of Forms?

May 20, 2009

I'm developing a form that displays conference attendee data.I have a panel control on this form and would like to put a series of buttons at the bottom of this form that will open other forms in the panel. So for example, there would be a button to open the Address form, another button to open the Email form, and so on.There will be 10 buttons total. I have the Address and Email forms set up so far and it seems to work pretty slick.

Before I go any further, is this the best way to do this? FWIW, all forms will have a datarepeater control on them since there can be multiple addresses per attendee, multiple emails, etc.

Random Row Choice From Sql Database In Vb

Jan 6, 2012

I have created a small sql database using new data source. i have placed buttons to move to next,previous,first and last row but i am wondering if there is a way of making a button which would randomly pick a row with information from database or just make it randomize them before they are appearing on the screen.

At first i have tried creating random number generator and then joining it with the coulmns in the database. I failed in the end even though i thought it was going to work. Then i thought maybe i have to change the query as in, instead of "Select that and that and that from database" i thought i have to write "Select that and that from database sort by rand", i also saw that some people write limit 1 or more afterwards but i have no clue what it is and didnt use it. Anyhow i tried that query and it didnt work.

EDIT: I also thought about adding all questions into array, or use some sort of indexing, but i have to use database as the requirement.

Also if anyone would be willing to give me an advise of what is best book i could buy, which would cover databases in sql and some beginner/intermediate programming in visual basic.

VS 2008 "Pacman" Ghosts Random Direction Choice?

Nov 20, 2009

I've got a small pacman-like game where ghosts are running around a maze. At the moment, their movement is completely random. Each step, they determine which directions they can possibly move in (taking into account walls), and then they choose, randomly, one of those directions.Now, this works, but it's not very good. If a ghost is in a long corridor where he can only move up or down (or left/right), then he will usually not go anywhere, but just move up, down, up, down, down, up, up, down, up, etc. So, while it does move every step, in the long run it doesn't go anywhere.

Customizing Obtaining User Choice

Jan 12, 2010

sample_form.rtf (1.48MB). Number of downloads: 36. I have a working form to give specific choices to the user and retrieve the user's choice. (See code below and attached image in WordPad file.) I know I can use a global ("Public") variable to pass the text of the three choices from the calling form to the called form, but is there a way to pass these from one form to the other exclusively? Of course, my main objective is to have as little memory being used as possible. I would like to make the form in my example (frmDialogChoice) a generic form that can display any set of three choices.

code within calling form:
Dim intSwitchToMake As Integer
Dim insFrmDialogChoice As New frmDialogChoice
insFrmDialogChoice.ShowDialog()

Detect User Choice During Run Time?

Sep 10, 2010

No doubt a simple question, but I'm a beginner (I learnt GW BritingASIC in 3 months long ago - but after 6 months grappling with vb 2008 I am still bewidered).

I have written a program that asks the user at run time to choose 1 of 40 buttons. These are themselves defined at run time. Whichever button is chosen the same algoritm will run (using different data). Question: To save writing the same Button_Click routine 40 times, what code should I write - and where in the program - to detect which of the 40 the user has chosen?

The question is displayed in a label and the answers on radio buttons. Problem one: I am using a random number generator to pull them but this allows them to be reused. How do I stop repeats.

Creating Array For Multiple Choice Questions

Nov 3, 2011

I am in the process of creating an array for a set of multiple choice questions but I am having a few problems. I am an absolute beginner at VB and I am creating a quiz that users will select one of three possible questions and then depending on their answer a +1 value will be added to the score. However I do not know where my questions and answers are supposed to go, from what I have read online I have to use (0, 1) format to give possible answers but I do not know how I would make the questions and answers display in textboxes on my form. At the bottom of my code I have also included code to randomise the questions although I am unsure as to if it is correct. At the moment I can run my form fine without any problems but my main issue is to how I will get the questions and answers linked to my textboxes on my form.

Public Class frmTest
Private ran As Random = New Random()
Public intScore As Integer
Private Sub cmdStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdStart.Click
'Turns the message box invisible when start is clicked

Imperial Leather Is The .NET Developers Soap Of Choice?

Sep 14, 2009

No not of the Simple Object Access Protocol variety, but Soap It seams that Imperial Leather is the .NET developers soap of choice. This means however that we will all smell the same, and will make detecting a fellow developer out in the wild a little more difficult, since you cant smell your own scent. May i also suggest that PEARS Soap is not only far more visually appealing than Imperial Leather, but it actually smells much nicer too. Plus the Queen buys it as well, so just think on that the Royal bottom gets washed with this stuff:what says the masses?

Setup And Deployment - Choice Of Icons For Desktop?

I'm practicing using the setup and deployment project. I can add a shortcut to the desktop and give it an icon to display without problem. Many applications have a choice of icons to display for the desktop icon; when we right-click on the icon and choose "change icon" there is a box that appears giving the user a choice of different styles of icons to use for the programme. My question is: how can I give the user a choice of icons to be able to select which one to display? Do I have to make a dll file or is it another method?

Syntax Choice For Type Parameter Variance In C# And VB

Apr 12, 2010

In both C# and VB, type parameter modifiers are used to express the variance of type parameters. For example, the C# version looks like:

[Code]....

Since variance specifications basically restrict where and how a type parameter can be used, I tend to think of them as additional constraints on type parameters. I'm just curious as to why they aren't represented so. I mean, why are they represented in both languages as additional modifiers on type parameters, instead of being added to the type constraint list? If they were type constraints, the C# version would've looked like:
