VB Form Has Frozen / Locked - Button Didn't Appear

Apr 21, 2011

I'm sorta newish to VB.Net programming, and in the program I'm working on (VB Express 2010, Windows 7) its as if everything has frozen. When I make changes to the code or the designer view, then run/debug the program, the changes don't get saved. For example, I put a random button on the form, saved it, ran it, and when I ran it, the button didn't appear.

Login Form - Reading If Account Locked Or Not

Apr 8, 2009

This is for a login form. I'm trying to read if the account is locked. in my access database I've tried using a yes/no column and use datareader.getboolean but that didn't work, so I tried something simpler and used a number column, 0 for account unlocked and 1 for account locked. then tried .getint32 .getdata .getvalue but none of them get the value that in the column. but the data reader part is working, it is getting 3 columns. So I have 3 columns and the correct ordinal for the accout_lock column but can get seem to get that value it holds.

Public Class LoginForm
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
Dim Command As OleDbCommand
Dim DBconnection As OleDbConnection

Frozen While The Application Is Running?

Oct 4, 2011

So I'm writing this VB.NET application, and it's doing things. But whenever I press a button to start some process, it does what it does except I can't click the window until it's finished. Otherwise the whole thing freezes. This essentially stops me from doing more than 1 thing at a time, because if I click another button (or anywhere) when something's running, it just freezes my program.

Why Didn't It Display The Rest Array

Jun 10, 2009

My project is like this. When I select from "TypeComboBox" and "BeanComboBox", the "PriceTextBox" will display the appropriate amount of the "Private PriceDecimal". But when I added the "Private SnackPrice", it will display only the 1st array, (0, 0) for both array. I try using "Select Case" but doesn't work. I don't know what the problem is. Or maybe it can't be done like this? One structure can have one array?

Private TransactionCoffeeSale(30) As CoffeeSale
Private NumberTransactionsInteger As Integer
Private SnackPrice(,) As Decimal = {{1D, 2D}, {3D, 4D}}

Forms :: Object Binding - Properties Didn't Set The Value?

Mar 17, 2011

it's about object binding, yes it's just a simple binding. but i don't know why it won't work.for summary, i will write about what i am doing:

1. i have one solution, and have two project in it. WaitressDataWin and WaitressDataObject

2. inside WaitressDataWin, i have 'waitressdata.vb' . this is my simple form , there are some basic textbox (waitress name, address, phone)

3. inside WaitressDataObject, i have 'waitressDataObj.vb' is where i put my object class, i have WaitressName property, WaitressAddress, and Phone.one of my property is like this, others are same except the name of course.

Private _WaitressName As String
''' <summary>
''' Gets or sets the Waitress Name[code]....

4. i create data source , that is object data source. i add reference so i can add my second project which is WaitressDataObject and set the WaitressDataObj as the data source.now i have datasource with three properties (WaitressName, WaitressAddress, Phone)

5. I bind my textbox, by dragging the WaitressName (in datasource) to my waitressname textbox .. so on to all my properties.., i also get bindingsourcecomponent, WaitressDataObjectBindingSource

6. then I put this code to my form load :

dim wdm = new WaitressDataObj
Me.WaitressDataObjectBindingSource.DataSource = wdm

7. done, it should've been worked, but it didn't , i don't know why.. , every time i fill one of my textbox, the properties didn't set the value, i put breakpoint in the 'set' part of all my properties but it never breaks anyway.. (the 'get' part is good, it read my property value when i load the form). so i just had problem in my 'SET' Part.

8. I think i had checked on my variable (word, case sensitive,etc), no problem.

Oct 11, 2010

On Windows Phone 7 to get the current control one would use

FocusManager.GetFocusedElement()

Wherea on Winform it is just ActiveControl.Why use 2 semantics which is a nuisance for portability ? Is there any difference of behavior you can see between the two ? If yes that makes sense, otherwise that doesn't.

Raise Event Because A User Didn't Not Select A Checkbox Option After Choosing A Certain Value In A Combobox?

Aug 4, 2011

I am new to vb.net and I have looked at other topics. I cannot find the answer I need. OK I have a combobox named cboRaceDesc and five checkboxes (CkRaceAfricanAmerican, ChkRaceAmerican Indian, ckRaceAsian, ckRacePacificIslander, and ckRaceWhite). I was going to post an image, but I cannot.cboRaceDesc has two options...Hispanic and Other. If the user selects Other then they have to choose one of the five checkboxes or it will raise an exception when the record is being saved. I am assuming I would generate the code under the "save" button. I know I need to gather the following information in my code:

If cboRaceDesc.SelectedValue = Other Then
<I am not sure how to code the logic regarding the checkboxes>
<I know I need to use multiple else/else if statements>
<I know towards the end I would generate the exception>
End

Can anyone help me fill in the blanks or point me in the right direction?

Save The Last Dragged Button On The Form And Also Detect The Name Of The Last Clicked Button?

Sep 5, 2009

I have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.
