Visual Basic Sql Command Not Returning Anything To Variables?
Jun 28, 2010
i am working on this code that is going to query a database for an entry and return the value of the tracking number and the time to print on a label if the tracking number exist in the databse. it does not right now it only seems to reprint the number that is enetered in a text box and it does not grab the date. here is the code.
Dim TrNum As String = Me.DupTNText.Text
Dim TrDate As <=something if it is even needed
Dim connectionString As String = "Data Source=XXXXX;Initial Catalog=YYYYY;Integrated Security=True;Pooling=False;Encrypt=False"
Dim cmdText As String = "SELECT TrackingNumber, Date" & _
In my code I enter a string in a text box and have the query check the server for the entry. If it exists it returns the string and the date into two separate variables. The database only has TrackingNumber and Date. Below is the code. As of right now i get "Invalid attempt to read when no data is present." at the "If (sdr("TrackingNumber") IsNot Nothing) Then" line.

I have a program that auto fills a section on a webpage, how can i tell this command to ignore the textbox if its empty? If i dont the software crashes because the following command needs the box filled in order to proceed.
I'd like to, let say "declare" my custom command, and what do I mean by command is something you type in the code, when for example you click a button. Just like Textbox (for example), my custom command sould have "underthings" in it, so just like I can type in Textbox1.Text. And that underthing (in this example, textbox is my custom command and .text is a sub/underthing) I can set if it is a boolean or string etc. I need this for my login program, where that custom command is an username (named username, what you can dim), and then it has sub things, like username1.email (string for e-mail text) and username1.password, username1.ismoderator (boolean, true or false). So an example, in my program I can do like this:
'Username is my custom command, just I don't know how to'define or declare it.'Username has here, to keep it simple, 2 sub things, it is'username.password and username.name Private Sub btn_registrate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn_registrate.Click'When the button called registrate (make new username) is clicked Dim username1 As Username'(I don't know if it must be dim blabla as NEW or without new with'my custom command)username1.name = Textbox1.Text 'Textbox for username username1.password = Textbox2.Text 'Textbox for password

In a while loop, I am writing a progressively increasing integer value (between 0 and 100) to the Value attribute of a ProgressBar control, when it disappears from the window in which it resides. I have verified at the time that it disappears that the Min is 0, Max is 100, and Value is a valid integer in range.
Does anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?
How do I disable the background compiler for Visual Basic in Visual Studio 2008?
For my sins, I have to work on a large VB.NET project and it often locks up for 20 seconds at a time whilst doing the very helpful background compilation
I'd rather work blind between compiles and be able to do some work.
I am just wondering how I can add Direct X references to Visual Basic in Visual Studio 2010 Beta 2. I cant find them in the .NET reference list, or the reference list, or anywhere.

I am trying to make a console program in Visual Basic on Visual Studio 2008. I want to ask the user of the program if he wants the premium version or the standard version.

I have Visual Studio 2008 Professional and I'm trying to make it so I can click a button to send the application to the System Tray and then click the icon in the System Tray to make the application come back.

I am very new to Visual Studio Application Development. I'm mostly a DB guy. I used Visual Studio as a Report Designer, not much of an .Net guy though I can understand it. I am now asked to create a .net application and I'm trying to create a "Hello World" starter app. I opened my Visual Studio, click File-New Project and all I see is Business Intelligence Projects and Other Project Types. My step-by-step guide says choose Visual Basic, Windows Forms Application. But I can't see it as an option.
I have visual studio 2008 installed and was using C#. I am now trying to find Visual Basic. I can't find it. Is there a way to download it or should it be somewhere in my visual studio program? I don't want to use vbexpress, just regular VB 2008.
