VS 2010 : Click Image / Webbrowser / HtmlElement Class / Multiple Identical Images?
Jan 7, 2011I need to click an image in a webbrowser from a Windows Form in VS 2010.I can click ordinary links using code such as this one:
Private Sub Button14_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button14.Click
Dim lnk As HtmlElement
For Each lnk In Form2.WebBrowser1.Document.Links
If lnk.InnerText = "the_text_of_the_link" Then
[code]....
When it comes to the second variation of the code I often get the following error message (exception):NullReferenceException was unhandled Object reference not set to an instance of an object.
Basically - how do I tell it to click on it only if there are two separate and unique strings of html code in a html tag?

Searching A Database With Use Of The 'LIKE' Statement?
Apr 3, 2009I am currently trying to develop a program, for personal use, that will monitor the lending of items of music equipments to friends and family etc. And, for my program, I have a requirement, which is the ability to search a relational database, for items loaned, through my program, based on criteria entered in a set of text boxes located upon the program's form. I have already set up the form, and have searched the Internet high and low, to no avail (probably didn't look hard enough).e,I would also like to make another request... if possible I would like to achieve this task with use of the 'LIKE' statement, so that I don't have to input the criteria in full, when I wish to search the database.
The database that I am using is a standard Microsoft Office Access database, saved in a '.mdf' format, and the database comprises of three tables; LoanTbl (which specifies the loan details), EquipTbl (which contains information about the equipment loaned) and a LinkTbl (which forms the relationship between these former two tables) - the reason for the LinkTbl, even though it may seem unnecessary, is because the data has undergone 'normalisation', so that it is stored in the most efficient way possible.
Also, whilst I am on the point of linking together my program and database, does anyone also possibly have any ideas as to ways in which to add data to this relational database; I do have coding for this, however, it only applies to a stand-alone table, whereas there are relationships between my tables.

VS 2008 Searching A .mdb Database?
Jun 11, 2009how to add and remove entries from a database and now I need to know how to search it. I'm going to be scanning a directory and subdirectories and adding all files found to the database. I need to check if the file has already been entered into the database before adding it.
I though it'd be simple and would just require looping though each entry and checking the item for each entry. I played around with a while loop a bit and ran into some problems. Like when the database is empty.
I don't want to half-ass some code that seems to work, since that'd probably be slow and inefficient.
Also what are the technical terms for a column and row in a database. I'd to use the proper terms in the future.
