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")

Probably bad code but I'm wondering why I'm getting these errors for the code below?
Value of type 'System.EventArgs' cannot be converted to 'System.Drawing.Image'.
Syntax error.
Private Sub rdbtnVisa_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles rdbtnVisa.CheckedChanged
If rdbtnVisa.Checked Then
pBoxVisa.Image = E:VBClassProjectProjectProjectinDebugVisa.jpg
End If
I've underlined an marked in red the characters that are spitting the error.

if 2 is generated image2.gif. However I have 52 such images to be displayed in 16 picture boxes so I was wondering
if there is a more efficient way than a select case method for each image and each picture box.

When I view images on my development PC they look fine, but when I view them on other PC's, the images are sized differently and often get cut off. I've tested this on multiple PC's and the images always get cut off.I've attached the images from my PC and another PC to this post, the image that is cut off if from a Windows XP PC.I'm using VS 2010 on Windows 7 64-bit.

I have a directory which has n number of Images (.jpg) files. I want to be able to show a print preview and print those Images. (Multiple Images should be printed on a single page, depending on Image size. Better if I can show the images in 2 columns, since images are small in size). I created a DataTable out of Images. (snippet below).

If you can take a look at the received tab [url] It is meant to display the hosted images full properties. It doesnt at the moment because it completly fills the tab with ugly information.Can any of you think of a better way to display the newly hosted images information.?Im thinking of just killing off the tab. But thats not very professioanl in case the user wants the full picture information?

I am using VS2008. I have a table in which the jpg images are stored. I can retrieve the images from the table and display it in datagridview. But many images are of different sizes. So the cell height of the datagridview changes according to the image size. Is it possible to give a fixed cell size for the image column and also shrink the image to that cell height.

I want to pre-load a number of images from the web, so that I can display them in a form, and scroll through them without delay. It can be a large number, but i only need to pre-load perhaps 20, and then remove/add in advance, as I scroll through. The images will typically be .GIF or .PNG, of quite small size, <50kb. The link for any single image will look something like this: [URL]..and I will keep a list of all the links I need to access.
What "type" shall I use to store these images? And how do I make web requests to put the data into this type? I guess it will be more convenient to keep this as in-code list of some memorystream type (?) instead of saving them to disk and having to deal with file names and stuff..? Also, what type of control shall I use to display such images? Do I use a PictureBox?And if a memorystream is indeed the best choice, how do I make this show in the picturebox?
