this is part of code for my checkbox.For Each c As Contact In contacts.Entries
counter += 1
tr = New HtmlTableRow
tc = New HtmlTableCell[code]....
now this will create 1 to n, checkboxes depending on the records pulled form DB. On the user side, i need them to check minimum one checkbox before clicking submit. howcan i achieve this?
I am reading values from a database (boolean) and if true, I want it to check a checkbox,and if false, keep the checkbox unchecked. The lines look like this: blEnergy.Items.FindByValue(1).Selected = track_usageIn this case, track_usage is a boolean value.This way does not actually create the check mark in the checkbox like I wanted it to. What is the best way to do this?
View 1 RepliesHow do I stop a storyboard which is created in blend and programatically running from VB?
View 1 RepliesAfter taking a few years off from programming, I decided to start learning vb.net. I have created a user control that contains a picture box. I added some custom properties to the picture box that will hold general string data from a database.
My problem is that the user control is programatically created during run time, and during this time a DoubleClick event handler is added for the picture box that is within the user control.
I need to be able to set the custom properties for the picture box during the creation of the user control, so that when the control (picture box) is double clicked I can read these values but am unsure on how to access them.
The picture box is the entire size of the user control, or I would just add the custom properties right to the user control and add the DoubleClick event handler to that. However, double clicking needs to be done on the picture box since it takes up the entire user control, unless anyone has an idea to trigger the DoubleClick event of the user control when the picture box is double clicked.

View 2 RepliesUsing ASP.Net MVC1 and am dynamically creating the html in a model that is then dropped into the view and rendered at run time.
My view is a single page that looks like this:
<%@ Page Language="VB" Inherits="System.Web.Mvc.ViewPage" %>
<%=(ViewData("Content"))%>
This dynamically created content is mostly dropdownlist boxes in the format of
<form method=post action="/questions/nextBatch">
<div id="text">What is your preferred drink?</div>
<select>
[Code]....
Is it is possible to perform validation on the dropdowns lists to ensure that a value has been selected? If any of the dropdownlists that still have the default value (the "please make a selection" text) the page is then redisplayed with the font colour of the question or dropdownlist box changed to say red?
I'm from the Webforms world and have made the switch over to MVC (which I really like!) and I know there are some pretty slick validation tools out there but you seem to have to account for them within the view itself.
I cannot pass a HTML helper through the viewdata of the controller as it does not render unless it has been coded directly into the view itself.
Also, I'm looking for a pure asp.net solution as I cannot use javascript due to accessiblity concerns. I can access all the values of the dropdowns without any problems throug the formscollection object but from there I'm a bit stuck.
I am dynamically creating a list of questions (Labels and TextBoxes in a table).Some questions need to be filled in, so I'm also creating the RequiredFieldValidators in the code behind.To display the ErrorMessages, I use a ValidationSummary.What I want to do is to display a '*' next to the TextBox and the question in the ValidationSummary.On the aspx page it could be done like this:
<asp:RequiredFieldValidator ID="reqFieldValWOline" runat="server" CssClass="errorLabelNoBox"
ControlToValidate="txtWOline" ErrorMessage="the question">*
</asp:RequiredFieldValidator>

I've tried countless other methods... none seem to actually get the checkbox ON/OFF value in vb.net.
I've got a form with parent-child setup. The parent displays name and other demographic info.The child displays multiple addresses, one row at a time. There can only be one primary address for a name and this is designated by a checkbox at the top of the child form.If the user wants to change the primary address to another address,then they find the other address and click on the checkbox.The form checks the other addresses and if one is found that is designated as primary,the user is warned that one already exists and prompts them to change it.
So for example, a name has 2 addresses, the 2nd being the primary address.The user wants to change the 1st address to be primary.They click on the Primary Address checkbox for the 1st address.A warning displays that there is already an address listed as primary.The user then answers the prompt to change the 1st address to the primary address.The checkbox for the 2nd address will be unchecked and the checkbox will be checked for the 1st address.My problem is getting the checkbox unchecked for the 2nd address.If I close the form and reopen, then the checkbox is unchecked.How do I refresh the checkbox for the 2nd address?Here is the code I'm using to find if an address has already been marked as primary:[code]......

I have a .NET dll which I use from a C++ program. Now I have to register the dll programmatically on a deployment computer. How do i do that (programmatically! not using regasm)? I remember, when I once called a VB6 dll from a C++ dll, I had to use DllRegisterServer and DllUnregisterServer. Is that still so with a .NET dll? It seems I have to somehow add the dllregisterserver function to the .NET dll.

View 5 RepliesI've written an interface with a 3rd party web service in VB.NET. The final step in that interface involves the 3rd party delivering to us (as a stream) a PDF document. After streaming is complete I save a copy of the PDF on our servers, so that our users can view the PDF by clicking on a link in our system. The PDF opens fine in Acrobat X, but when I try to open it programatically I an error saying that "the file is damaged and could not be repaired". I can also open the file in IE just fine, with no issues, and the same code that displays this PDF works just fine on lots of other existing PDFs that predate the 3rd party interface.
I have emptied out temporary internet files as suggested in some posts I saw online. I also opened the PDF in Notepad++ and the %PDF tag is first, and the %%EOF tag is last, so there's certainly no corruption visible in the document source that I can see. Below is the (very standard) code we use to open PDFs into a separate browser instance on our site:
