I have a custom control that builds what we refer to as "Formlets" around some content in a page. These are basically content "wrapper" sections that are tables that have a colored header and provide an open TD with a DIV in it for the content of this formlet. (The DIV is for DHTML to hide and show the content) I've created a web page...

I see that the Application_OnStart event is fired only once for a certain application. I'm interested in creating a "global" object (an object that will be available to all requests for the application). I thought I could use this event to create an instance of my object. I find that the event does get fired and an instance is created....

I have the Microsoft Press: Developing Microsoft ASP.NET Server Controls and Components book. It's starting to shine some light on control development but there is something about composite controls that I don't understand... I've included a snippet from Chapter 12 below on Composite Controls: <start> Override the CreateChildControls...

I'm reposting this because I really need some advice. I have a web app that makes many queries to the database on every page. In order to save development effort, I've consolidated all database querying to methods in a single static class, so whenever I need data, I pass a SQL string to a method and I am passed a datareader or else...

I'm constructing an ASP page that I'd like to test by writing a program that simulates "many" users hitting the submit button on a form. I assume it's possible to manually construct an httprequest object, but the docs are more oriented towards using one that already exists. Am I on the right track or is there an easier way? In my case the...

Now they want to add new features change some of the existing ones, it's not a major rework, but probably a week of work or so.

I think I'll never come across that error. It happens when running code from a DLL that tries to write to disk. I added permissions in the project folder, the wwwroot and in IIS to NETWORK_SERVICE and Everyone, with Full Control to see if it's a permissions problem. The project is hosted in a Windows 2003 Server and developed from PCs in a...

In one of the applications that I'm working on I have 2 sets of functions that build different datasets. Imagine 4 columns in a datagrid. Inside those 4 columns I have nested datalists. Two of the datalists' datasources point to database A and the other two point to database B. This effect allows the client to perform a side-by-side...

When a user clicks one of these hyperlinks, he will navigate to another aspx page (referred to here as page_2).

It works, but connection string to the database is hard coded, as in this method : public DataSet GetCategories() { SqlConnection conn = new SqlConnection("Data Source=DEVSERVER;Initial Catalog=XXXX;User ID=X;Password=Y");
