I don't think it is night time that is the problem, just the long run time. I take bitmaps and place text on them then convert them to icons so that the image can be used on the system tray.

View 3 RepliesMy 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}}

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.
My histogram report didn't show the data in the database.
View 2 RepliesI'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.

what MSDN is trying to indicate here on this tutorial, ref this page: Walkthrough: Creating a SQL Server Express Database.I cannot make this happen in VS2008 SQL Server 3.5 ? To create a relationship between the tables created in the previous step 1.Right-click the Database Diagrams node in the SampleDatabase.mdf node in Server Explorer/Database Explorer and choose Add New Diagram.
2.Click Yes if a dialog box opens asking to create the required database objects for diagramming.
3.Add the Customers and Orders tables to the diagram.
4.Close the Add Table dialog box.
5.Drag the CustomerID column from the Customers table onto the Orders table.
6.Verify that the Customers table is the Primary key table and the Orders table is the Foreign key table, and verify that the CustomerID column is selected for both tables.
7.Click OK to close the Tables and Columns dialog box.
8.Click OK to close the Foreign Key Relationship dialog box and create the relationship.
9.Select Save Diagram1 from the File menu.
10.Leave the default name and click OK.
11.Click Yes in the Save dialog box.
I can create relationships but not the Diagram ?
Strange problem: This code gives the appearance the I have 'Split' 1 button into 2 (B -> B(1) & B(2)) and then can 'Join' them back(B(1) & B(2) disappear and B returns). All this works fine, 'cept when I try to declare the only container where this can happen. The 'Control-S' part works as long as the lower portion is commented out, when I uncomment the lower portion 'Control-J' neither part works - the code skips down to the msgbox -
If e.Modifiers = Keys.Control AndAlso e.KeyCode = Keys.S Then
If DirectCast(sender, Button).Parent Is flp1 Then
MakeButton(sender.text & "(1)") 'sub that makes the button passing the text thru

I have a website that i've been working on for about a year now.Recently, it's started throwing System.AccessViolationException every now and then, in my dev machine, mostly, when I was away from the machine.I haven't changed anything on the server code in weeks, since I've been working 100% on the Javascript part, and this error started appearing recently.
Also, the code I'm doing is 100% managed. I'm not doing any interop, calling strange DLLs, nothing. It's pure VB.Net, so I don't see how I could be generating one of these myself.Now, I've been using this new machine for a couple of months, and it's not working 100% right. Every 2 or 3 days I'm getting a blue screen for example. I haven't had time to diagnose it properly, but I'm suspecting I may have a faulty RAM chip.

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?
