This seems really dumb but I go to this site - [URL] and click on the link for Visual Basic 2010 Express, select English as the language and I get the file vb_web.exe. The file installs Microsoft Visual Web Developer 2010 Express. All of the tools in it seem to be for web development only.Where is vb express 2010 download for creating Windows forms, console apps etc.?

I am having difficulty retrieving the correct PIN code from my database, for an ATM banking application. When someone enters a correct PIN code that is already in the database, they gain access to their ATM account. If incorrect, then a message box appears. I am having an unusual problem where, the system is partially working. The code I have, is preventing the user from accessing their account, in the correct manner, eg. message box pops up. However, it is also not accepting the correct PIN code. The most unusual thing about this, is that, if the user enters the number "1", the message box won't pop up, however it will still block the user from accessing their account. And even stranger again, after entering the number "1", trying it, then erasing it, if they enter the correct PIN after this, it will allow them to access their account.
Here is the code:
Public Class ATM2
Dim Pin As Integer
Public Sub Retrieve()

View 24 RepliesI am having some trouble getting the correct syntax for a bit if code. I am using vb to insert data into a db and outputting the data as XML, here is the code
<WebMethod()> _
Public Function addTrack(ByVal tTitle As String, ByVal tAlbum As String, ByVal tGenre As String) As String
Dim conn As New SqlConnection("Data Source=MARTIN-LAPTOPSQLEXPRESS;Initial Catalog=mp3_playlists;Integrated Security=True")
Dim sql As String = "INSERT INTO Tracks (trackTitle, trackAlbum, trackGenre) VALUES ('" & tTitle & "', '" & tAlbum & "', '" & tGenre & "') FOR XML AUTO, ELEMENTS"
[code]....
The code is for a ASP.NET web service, when I click invoke on the website i get the error Incorrect syntax near the keyword 'FOR'. If I remove FOR XML AUTO, ELEMENTS everything works find, db updates but I dont get the data to output as XML. I think the issue is with the brackets required for the insert values because this issue does not occur if the SQL statement is a SELECT statement which has no brackets but i just cant figure out the correct syntax?

View 1 RepliesWhat is the code for ignoring the case of an entry while checking to see if the entry is correct or not... (i.e. in a flashcard program... given definition, asks for the name) I don't want the case of a character to affect whether the answer is correct or not.
View 2 RepliesCODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)
I have created a basic query generator which allows a user to select the Select, WHERE and criteria attributes using a number of checkboxes.However i have got stuck. In the results form i have the following code
Private Sub DisplayRecord()
RichTextBox1.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(0)
RichTextBox2.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(1)
RichTextBox3.Text = ds.Tables("newResults").Rows(intCurrentRecord).Item(2)
[code]....
The program keeps on crashing if the user does not select the corresponding amount of display records from above for the amount of attributes they want for the SELECT part of the query in the intreface in form 1.
How would i go about making something where the number of SELECT attributes selected which are listed in a string create the correct number of textbox fields in the results form (form2)
