I'm trying to export the details in my datalist into a PDF file by using this third part program called Itextsharp. However, I'm encountering problems in generating the PDF as it keeps giving me the "Object reference not set to an instance of an object" error which points to my "htmlparser.Parse(sr)"
I been trying for 2 hours now to fix this problem however no progress. Does anyone here have experience in Itextsharp?
Here is the code that runs the export to PDF command
Protected Sub Button15_Click(ByVal sender As Object, ByVal e As System.EventArgs)
Response.ContentType = "application/pdf"
Response.AddHeader("content-disposition", "attachment;filename=Resume.pdf")

Got a problem that's hopefully a quick fix. I've got a homework assignment where I have to link an access database file and allow the user to go through the records, add/delete records and save the file.
When I run the program everything seems to work fine, except when I hit the next button to go to the next record, it always skips 2 ahead, from 1 to 3 and 3 to 5. The previous does it also and when I click the delete it deletes 2 records. I can't figure out why it's doing this. The table we linked was already created for us so I don't believe that it is a problem with that. One weird thing I noticed is that it shows that there are 5 records so I wouldn't think that it is seeing 2 as 1.
Here is my code for the buttons:

I made a code that will change the background button when the mouse cursor over it, the user press and release it ,and it work great.The code below is a part of the code I made, which will change the background of the button when click by user.
Method to use:
butclick(sender)
Sub butclick(ByVal butname)
'code reset of button background start
Main.bestassi_bluebut_about.BackgroundImage = My.Resources.buttonbg
[code]....
But I had to reset all of the background of the button first, the picture below explain why I need to do like this:
BEFORE ALL BUTTON CLICKED BY USER:
IF NOT RESET AND ALL BUTTON CLICKED BY USER:
IF WITH RESET:
So is there any better code for this? Because my method seen a bit silly. Is there any code that can change the background of all the button in one time?
I am having a problem with passing a button and form to a method.Let me explain detail.
when i click a button it will send some this button and a form to a method. The method then do some job.[code]...
I have a custom application I am developing in vba. I have written all the code and the only thing I am confused about is how to configure a button to actually "start" or "run" the program. On the form on the user side, the user will type in an item number, then a button will be pushed that brings up a bunch of fields and textboxes on a new small form for the user to enter, The window displays the default values and will update/save new or updated fields and insert it into the database.
The button is designed in microsoft-gp but I have to manually code it to run the program. Right now, when I click the button, the window pops up, but no information is displayed in the textboxes nor are the combobox values being displayed.
Private rs As Recordset
Public Sub Main()
DisplayWindow
'Item Number is the primary field for pulling data
[code]....
When I run these two methods in vba, the information displays on the form and works 100% Now I have to code the button on the original form so this is what I have ; Test = name of the button
Private Sub Test_Changed()
frmItemProfile.Show
End Sub
How can I code the button to run the program properly?
When you click on a button control on a web form visual studio automatically put in this code for you in the code behind.
Protected Sub btnSave_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnFlightInfo.Click
end Sub
Say for example, I wanted to call this method from another method. How would I do that? I know that the sender is the actual button object, but what is e? Here is what I have so far inside another sub. Just trying to get a better understanding of how this method works.
btnSave_Click(btnSave, ??what would you put there??)
So Ive got some code thats in a public sub outside of my button.
Here is that.

How can I call that method from a button click event?
What code goes between the

This is obviously not entirely my code, E.G. the few errors from my attempt at implementing, however, before I even finish that Id like to know how to call that method from a button or form load, or any other event for that matter.
May i ask you based on your codes last time to create a button, is this how i modify to delete off the button after i clicked on it? So that means to say i click on this button at location 15,41 then only this button will be deleted. the below is my code to delete the button but it is not consistent as sometimes it can delete more than one button when i click on one button.

I'm creating a VB.NET application that includes two radio buttons inside of a groupbox. If the first radio button is selected, a certain tab on a tab form should be enabled. If the second radio button is selected, that tab should be disabled.
Is there a groupbox method that monitors both radio buttons and fires when the selection changes? Or do I need to set up individual methods for each radio button?
I have a UserControl, we'll call it myUC, that is one among several UserControls in the main window(myWindow) of my WPF application. myUC contains a number of standard controls, one of them being a button, we'll call it myButton.
When I click myButton, I would like to execute myMethod, which exists in the code-behind of myWindow.
The problem being that myUC doesn't have any idea that myWindow even exists, much less that myMethod exists.
How can I send the message: 'Hey, myWindow, wake up. myButton on myUc was just clicked; run myMethod'?

I have been searching around the web for a solution to this issue but have come across nothing so far.Basically I have a table as shown below, which I made up of ItemTemplate fields and is populated by a DataSet from my database. It shows brands to the user of which they can then click and go onto another page.I need to add another option to the table called "All Brands". Thus then I can use this to go to a page showing all the brands.However I can not seem to easily add this into the DataList.

I am completely Goggled out on this one. We currently have a datalist consisting of rows of data for our company. What I need to do is to add a link into the individual cells of a particular column called candidate profile. The link will be View Notes. When that link is clicked, I would like to have a new row expand right below the existing row to allow the additions of comments in the empty row. When the user comes to the page and there are existing comments for the row of data, have it expanded and give the user the ability to expand, or close the comments as they see fit. I also need to figure out the best way to allow the user to enter in the comments as well.

View 2 Replieshow I would put a maximum of rows in a datalist. I have the program reading from a db and I just need to limit the amount of users in the view. The database is organizing the users according to rank and I have it so that it will read the users by rank in descending order (highest rank 1st) I need to limit it to 5 users. Is there a method for this? P.S. I put this here because I know that this is more of a vb.net code oriented question(limiting amount of data shown by an object)
