How To Access Non-asp Img Tag From Code Behind
Nov 3, 2011
We're working on a big project and we're stuck a bit here.I need to access the <img>'s from an .ASPX from the code-behind on the PageLoad() to assign the right image (attrib src) depending on the value we just collected from the DB from an SQL Query.We can't use the runat="server" attribute to see it server side because we got a bunch of jQuery using the img name tag to work with.I'm sure there's a way to access and modify the src attribute of the images from the code behind view?

I have a similar problem posted in the forum similar to this : started learning VB. I am not able to get my example code to work to access an Access database through automation. The author of my book suggested that I might not have the correct Jet 4.0 engine. The specs I have are: MSJet40.dll, Dated 7/14/2009, Prod Ver 4.00.9756.0.

I have and application in VB 2005 that runs on a 32-bit os right now. One of teh first things it does is call a an API from Novell GroupWise like such, which allows ir tun on either OS but I can't email from the program like I can on 32-bit. Is tehre anyway under the 64-bit section to use the api which on the 64-bit box i assume is in (x86) since GroupWise client installs as a 32 bit app.'determine 32-bit or 64-bit OS
If IntPtr.Size = 8 Then

I have a Crystal Report that I am trying to access thru my VB.Net app. My problem is that I keep getting a "Database Logon" prompt (see screenshot). My code is below and I think I might have more than I actually need. I created the report from with the VS 2008 IDE.
Private Sub rptSingleWorkOrder()
Try
strSQL = "Select A.productName, " & _
"A.productDesc, " & _

By the way, this code runs cleanly completely thru from the time the procedure is called until it exits.

I'm currently working on my VB.NET certification and I'm using Murach's Visual Basic 2008 for my class textbook. Chapter 16 of the text covers writing my own ADO.NET data access codes. The code I have included here is for two classes of the project:
frmAddModifyCustomerDB.vb is prewritten by murach for this assignment and CustomerDB.vb is included written in the book as my assignment to build but not prewritten for me in the solution. According to the assignment, frmAddModifyCustomerDB.vb should not be modified unless instructed by the book. The procedure in question is Private Sub btnAccept_Click on the line that reads: "If Not CustomerDB.UpdateCustomer(customer, newCustomer) Then".After copying the CustomerDB.vb class directly from the book the assignment stated that the database should update properly when using the UpdateCustomer function that is fired when the Accept button is clicked. Every time I tried to modify a customer when doing this I kept getting the Database Error message box and the changes would be canceled.
After playing with the code I changed the "If Not CustomerDB.UpdateCustomer(customer, newCustomer) Then" to check against the boolean return from CustomerDB.vb by inserting "= False". When the modified code reads "If Not CustomerDB.UpdateCustomer(customer,
newCustomer) = False Then" the application updates properly and does not fire any exceptions. I'm confused by this because the book specified that I should not need to modify the code for the Add/Modify form in order for this to work.
Public Class frmAddModifyCustomer
Public addCustomer As Boolean
Public customer As Customer

I am working on a form with several databound textboxes, each with its own label to identify it. I would like for the label to enable/disable based on code logic. I see the label properties in design mode, but cannot access the label properties in code. The intellisense tells me my label name is not declared. Am I not able to access label properties as in vb6 or the same as a textbox?

I am creating a Microsoft Access 2003 database which will be using Visual Basic code in the backend.I have a form called frmReports. On this form are three option groups consiting of checkboxes. What I want to happen is if one of the checkboxes is checked, then the other two option groups are made invisible.
The context of the problem is a teacher is reporting on pupils. If a pupil is marked as being absent from class, the other two option groups (Behvaviour and Homework) disappear as no other information can be input.

One of my application is taking a lot of time on Windows 7 compared to XP. What application basically does is it creates some PDF files reads the content and emits on a form and then deletes the files. I ran ANT profiler on both XP and Win 7, and i could notice some differences. On win 7 some CAS related methods are widely called and those method calls were missing on XP.. Is this the reason ? If someone has faced similar issues,

I am trying to convert a C#/XNA project to a VB.Net project with access to the XNA framework. I have added all of the XNA framework as references in the VB project and imported them as well.Most of the code translation is going well but I am getting mixed up with some graphics issues and some event handling issues (neither of which do I understand in any languague). I have tried to puzzle it out but am digging myself a deeper hole with each attempt.I am ok with converting the variable declarations and the first three lines of the Game1 Sub. It is when we get to "graphics. preparedevicesettings . . . " that the trouble starts.

I recently just started working somewhere which will involve me coding VB in MS Visual Studio .NET 2003. I've been trying to refresh myself in VB by reading things online, but I just discovered an error while trying to run some practice programs (attached as error.png). Basically it says that I need administrator access.I'm waiting on an IT guy to grant it to me, but in the meantime I'm trying to figure out if there's a way that I can test my code without being an administrator.

I have a checkbox and a panel inside of a FormView control, and I need to access them from the code behind in order to use the checkbox to determine whether or not the panel is visible. This is the code that I originally used, but since I put the controls inside of the FormView, it no longer works.
Protected Sub checkGenEd_CheckedChanged(ByVal sender As Object, _
ByVal e As System.EventArgs)
If checkGenEd.Checked = True Then
[Code]....
There aren't any errors anymore, but nothing happens when I click the checkbox. I think there needs to be some kind of event to trigger it but I don't know how you can put an event handler inside of an event handler.

I've just been forced (by hurricane Irene) to shift from XP and Access 2003 to Windows 7 and Access 2010 with no time for testing or evaluating changes.All our databases are still Access 2000 format.Our offices were flooded and our servers got moved around, though they're all still named the same things, and in many cases things are working exactly the same.However, I have a database that I can't connect to.It's an Access front end that links to tables in an SQL Server 2005 back end.When I start up this particular database the first thing it does is fail when running code that had been put in to set up ODBC connections when one didn't exist on the computer that was trying to access the data.[code]I didn't write this code.
