The program is currently trying to pull information from three different database tables and compiling the information onto one screen, to do this i am using three different connections and a function to handle the data at each stage. The issue is as my code hits PageLoadStage of "2" and runs the QueryDatabase() Function i am encountering an error of: "OleDB exception unhandled: No value given for one or more of the required parameters." This occurs on line 15 of the first code snippet. Can anyone explain this and/or identify any code issues if that is the cause.

View 1 RepliesI've currently got a service that produces xml files every 10 seconds containing server information. I'm looking for a way to display this on a web page.

However how can I use AJAX? Should I add a ASP.NET website to my visual studio project? OR should I look to use javascript & AJAX in something like dreamweaver? I'm very new to programming so i only really have a bit of experience in vb.net.
View 2 RepliesI am trying to take specific information from a web page and then process that information so that it can be sent to a label or text box.Previously, I had wanted to do this by using Regular Expressions. I've looked around and it seems that using regular expressions to parse information isn't always the best way because website aren't always coded to standards.Regardless, learning regex isn't working out too well for me. So, I was wondering if there was another way to do this?I was thinking that I might be able to use the web browser control. It would be ideal to be able to see the page in the form, select the information, and then be able to display it.

I am trying to scrape it using the webbrowser control using the WebBrowser1.DocumentText property, but it doesn't even show the links simply when I view the source in ie. I am sure this has something to do with the javascript it uses to load up the page or maybe iFrames,

View 10 RepliesI have two comboboxes and a listBox to display data from several databases. The whole process should be that after an option is selected in the first comboBox, the second comboBox and the listBox are populated. So for example, I could select a Company from the first comboBox, and the second conboBox will be populated with all it's locations while the listBox will first display the location of the headquarters(default location). But the user can then select a different location from the second comboBox if they want to and the listBox will then display the location of that newly selected office location.how do I dynamically pull these data from various databases cause all the companies will have their information in separate DB's. My challenge is how to dynamically pull these data from the various DB's to populate these 3 controls.
