I’ve run into the problem a few times now: How to pre-authenticate .NET WebRequest calls doing an HTTP call to the server – essentially send authentication credentials on the very first request instead of waiting for a server challenge first? At first glance this sound like it should be easy:…

Man I can't believe this. I'm still mucking around with OFX servers and it drives me absolutely crazy how some these servers are just so unbelievably misconfigured. I've recently hit three different 3 major brokerages which fail HTTP validation with bad or corrupt certificates at least according to…

The dynamic type in C# 4.0 is a welcome addition to the language. One thing I’ve been doing a lot with it is to remove explicit Reflection code that’s often necessary when you ‘dynamically’ need to walk and object hierarchy. In the past I’ve had a number of ReflectionUtils that used string based expressions…

I’ve written quite a bit about Visual FoxPro interoperating with .NET in the past both for ASP.NET interacting with Visual FoxPro COM objects as well as Visual FoxPro calling into .NET code via COM Interop. COM Interop with Visual FoxPro has a number of problems but one of them at least got a lot…

I want to create a GraphicsPath and a list of Points to form the outline of the non-transparent area of a bitmap. If needed, I can guarantee that each image has only one solid collection of nontransparent pixels. So for example, I should be able to record the points either clockwise or counter-clockwise…

Is there anyway to change the coordinates of some of the points within a GraphicsPath object while leaving the other points where they are?
The GraphicsPath object that gets passed into my method will contain a mixture of polygons and lines. My method would want to look something like:
void UpdateGraphicsPath(GraphicsPath…

I am creating a rounded rectangle GraphicsPath (see red outline image below), and then using this as a clip region both when drawing graphics, and as the Region of a Form.
Unfortunately, although the path looks good, it doesn't work well as a region (see solid black image below)
Is there a way…

In a form I draw a graph. This graph has some distinct paths that should have differently drawn. Say AxesPath, SalesPath, CostsPath etc...
When I resize the form need I to scale every of components Paths?
Take an example:
Imports System.Drawing.Drawing2D

Dim lineOne As GraphicsPath
