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}}

I have the following
Public Class Form1
Private GIFAnim As Image = Image.FromFile("c:cointosscointoss_ani.gif")
Private frames As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[CODE]...
Now I would like to put a wait in after the line:
frames = GIFAnim.GetFrameCount(Imaging.FrameDimension.Time)
ImageAnimator.Animate(GIFAnim, AddressOf paintFrame)
This is so that the animation has time to play and stop and then the rest of the code will display the other picture and the numbers. Is this possible? I tried timer and sleep but I cant get them to work.

I have to search within an array and display the number of occurrences that a value within the array appears. I know that my code is incorrect but this is what I have so far. If anyone can point out what I am doing wrong that would be great.
Private Sub btnResult_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnResult.Click
Dim intSearchAmount As Integer
Dim intCounter As Integer
Dim intIndex As Integer

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.

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.

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.

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?

I am currently developing an application using VB.NET in which I am using the REST WebServices. I have been able to do the basics with REST, however, I have not been able to add an attachment (more specifically upload a file, using REST which gets attached). I have done extensive research online, but so far I have not been able to find any working examples in VB.NET. To actually upload the data I use System.Net.WebClient. The following VB.NET code does the important work:[code]As you can see, the postString is converted to bytes and then uploaded to the server. However, I do not know where or how I should be posting the raw attachment itself. The documentation for the service we are specifically using states to use a variable "attachment_ 1," which I added to the postString variable, but I am not sure what the next step should be. Should the file be converted into bytes and appended to the postBytes variable?

When I start typing a variable (or whatever), VB pops up a little box with all possible variables starting with the letters I already typed. It's really smart!
However this option has somehow been disabled. How do I enable it again?

I have located some sample source code in visual basic to call a REST API. However, I need to modify the code by adding two request headers.
' Create the web request
request = DirectCast(WebRequest.Create(sURI), HttpWebRequest)
'Update request headers with request pairs Header1/"header1 value" and header2/"header2 value"
??? HttpWebRequest.headers.Add ????

For this program im using http method post to recieve messages from the server, when its waiting for a new message to be sent it locks the program up. No biggie, ill just thread the sub... Bad idea... I also have functions "send", "Connect", "disconnect". All on threads... i looked at task manager it started getting up to 100+ threads. I dont know much about threads but that just seems way to much. they will die off and the count will return to 20 but id like to find a different way of keeping the program from locking up but not having 100+ threads.. Little off topic: i used a user control. The only problem now is on the tab, its not anchored with the rest of the form... how do i accomplish this?

If I use the exact same thing but I say txtFirstName.Text = "found", Then "found" shows up in the text box when I click the button and the first line is true.
That tells me that there is a value in .strEmployeeNumber, and it is in the *same* array as .strFirstname, so there should be a value in .strFirstName as well. But for some reason, when I click the button and the first part is true, it overlays a string.empty and clears the box instead of the First Name.
