I'm coding an ASP.NET page, with VB code behind. When the user clicks a button on the page, I send them an email with information and instructions. Rather than sending a plain text email, I send a nice, pretty, HTML-formatted one. Right now, I'm doing this in a way that I KNOW will be difficult to maintain. That is, I'm straight up writing out all of the html. [code]...

View 4 RepliesI have 50 checkboxes that I need to write onto an aspx page. Each checkbox comes with 3 textboxes.[code]...
Now this shall go for all 50 states, depending on which states the person wishes to donate. In each state's row shall be a checkbox. So initially the page shall have value 0.00 in donation and new donation checkboxes, but all 50 states shall be visible. When the person puts a value of donation in certain state, that state shall get "checked" value and the donation, after submitting. On reloading, the value shall be populated automatically and checkbox checked automatically.
How do I make these 50 checkboxes in VB.NET?

View 1 RepliesI'm using the following code to retrieve a URL and then parse the HTML from the page:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnStart.Click
Dim Temp As String, searchstr As String

I think my problem is that I don't exactly understand how I am supposed to start and end the parsing. I know that in my above code, the "meta" tag is the start and the chr(34), double quotes, is the ending.
When I modify my code, I have price line, which in th html ends with another character, the ">" sign. In the first code, the "content" tag doesn't end with another character, it just continues the line, which is easy and it works.

View 2 RepliesI have a master page which contains everything that inherits it within a form. A page inheriting from it needs to run some javascript to act on a text field on a page. However, I can't seem to reference that text field through the javascript, since the form begins on the master page. The following line will come up bogus: document.form1.txtFindUser.value = blah.responseText; This is because form1 is defined on the master page, while txtFindUser is on the current page.

I have an aspx page with three web controls: one to control the List Users page, one to control the Edit Users page, and one to control the Add User page. I have discovered a method for accessing these elements, but it seems to be limited. Here is what I have done:
Protected Sub editUser(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewEditEventArgs)
'set selected user from gridview.

This works in most cases. However, I am unable to access the "enabled" attribute of these web controls. Why is this, and how might I access that attribute?
I am trying to check all the checkboxes on a webform (aspx) page, which is inside a master page,depending on the ID of the checkbox.

I have a parent page and child page, both aspx. All is working, but now I would like to close child page, if user leaves child popup page and goes back to parent page and clicks on something else like page index of Gridview. I CANNOT close popup child page if user goes to another app, or some other location, I only want to close if something on parent page is changed.
I have the PageIndexChange Event set up for other purposes, I would just like to add some functionality, perhaps a script manager to close the child popup page if the Gridview index is changed, java or another way which ever works best.I think I might also need to check if the child page is even open.

dynamically creating buttons with images in them and then accessing the on click event for that button. However lets say for example I have three buttons created during run time, button 1, 2 and 3 for simplicities sake. Each button needs to correspond to a value (lets say one, two and three). The problem comes in when i want to, for example, click on dynamically generated button 3 and have it display "three" in a message box. But button 2 might close the program. How can i reference an event when i don't know which button corresponds to which action..

View 1 RepliesOn my main form I have a 9 button grid that I need to fill with a gradient colour so that it represents a "heat map" going from Green (lower left) to Red (upper right). The "heat map" needs to be generated dynamically as - if I use an pregenerated image I have noticed colour variances when working on different screens / projectors as in the app there are other dynamically generated graphics & the two sets of colours need to match.So to achieve this - on my main form I have a PictureBox that I fill with the gradient colour.On top of the PictureBox I place my grid of 9 buttons.I then hide each button & take a screenshot of what is behind it & that then becomes the background image for the button. The button is then made visible.All works fine when I am testing in on a simple form The issue is that this arrangement needs to be placed on a tab control & I'm having difficulty replicating what I could do successfully on the simple form.....
Code for the colour gradient :-
Dim A As Integer
Dim B As Integer
Dim C As Integer
Dim D As Integer
