From VB6 to .net via COM and Remoting...What a mess!
I have some legacy vb6 applications that need to talk to my .Net engine application. The engine provides an interface that can be connected to via .net Remoting. Now I have a stub class library that wraps all of the types that the interface exposes. The purpose of this stub is to translate my .net types into COM-friendly types. When I r...
.NET: What is the purpose of the ProhibitDtd property in XmlReaderSettings? Why is DTD a security issue?
The documentation says: When set to true, the XmlReader throws an XmlException when any DTD content is encountered. Do not enable DTD processing if you are concerned about Denial of Service issues or if you are dealing with untrusted sources. If you have DTD processing enabled, you can use the XmlSecureResolver to restrict the...

What's an efficient way to tell if a bitmap is entirely black?
I'm wondering if there's a super-efficient way of confirming that an Image object references an entirely black image, so every pixel within the bitmap is ARGB(255, 0, 0, 0). What would you recommend? Most of these bitmaps will be 1024 x 6000 pixels (although it's not safe to assume they'll always be that size). I need this because we'r...
.net, do you get a transaction object?
Working with SQL / ADO, got me thinking about something that I think should logically be included with the .net framework, and I was wondering if such a thing exists, let me explain.

When using WebBrowser control how do you have the text appear without margins?
I'm using a System.Windows.Forms.WebBrowser control next to textboxes with the left margins of each control aligned on the same X axis. The appearance however is "ugly" because the WebBrowser control inserts a margin/padding around the content of the control. Therefore the text in the WebBrowser control is several pixels to the right of ...
