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"

how to create a sub category in vb.net? well I'm thinking of building a sales and inventory system of computer parts and peripherals and here's the logic. I'll be assigning each of them category like for example:
Componenets[INDENT]Peripherals[/INDENT][INDENT]Networking[/INDENT] - Processor[INDENT]- Chasis[/INDENT][INDENT] - Router[/INDENT] - Memory[INDENT]- keyboards[/INDENT][INDENT] - Bridge[/INDENT] - Storage[INDENT]- Speakers[/INDENT][INDENT] -Hub[/INDENT] - Optical Drive[INDENT]- Flash Drives[/INDENT][INDENT] - Switch[/INDENT] - Graphics Card
There you go. and the main categories are: Componenets, Peripherals, Networking and the Subcategories are with the -(dash) on their names if you have an idea also on the database structure please give me also some tips about how to construct the database tables.

I wrote a VB 2010 app on a single core processor utilizing performance counters which runs fine. However the release exe fails on my quad core, trapped by the OS on its first access to a PerfCtr. I've loaded VB Express Studio into the quad core
and when running the app in Debug I get this error "Cannot load Counter Name data because an invalid index was read from the registry." Similarly, adding a counter to the app on the quad machine results in the empty drop-downs for category and it sub fields.
where I can get an update to these registry entries?

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.
