Hello. I am trying to have my application (C# under .NET 3.51 SP1) recognize that a file has come from a "safe" source. My approach was I would sign the application and then, at a later date, I would use the private key from the same snk file to sign files. The application would use the public key (easily obtainable) and calculate if t...
I'm upgrading an application that was using jQuery 1.3.2 to consume a WCF Data Service (a.k.a. ADO.NET Data Services, a.k.a. Astoria) to use the latest version of jQuery (1.4.2). My application is now failing, with JSON parsing errors, because jQuery 1.4 now uses stricter JSON parsing. I've run the JSON returned by my data service throu...

The way I'm thinking to do it is as follows but the problem is that my Body field can get very big, and if i add it as string it gets ugly.

In a windows/.net environment I currently use castle monorails with jquery to provide an administrative interface to an e-commerce application. This application works nicely, but has no real concept of ui composition. Up to now this has not been a problem, because the ui was targeted to a single user base, and a single domain object. Th...

Hi, I'm curious as to what is good practice when it comes to certain scenarios involving nested types in .NET. Lets say you have a Wheel class, and the Wheel class holds Bearing objects. A Bearing object only makes sense within a Wheel and you do not want to allow it to be created independently, so it would make sense to have the Bear...
Hi all, is there any way to throttle the cpu usage of a windows service that is written in .NET, either inside the service code or outside. Setting the current thread to the lowest priority is not an option but as soon as exceptions start to occur the cpu load goes up, is it possible to limit this? thx in advance, greetings ...
We have a WPF app that allows our users to download encrypted content and we want to provide the ability to decrypt this content off-line. The idea is to download the keys and store them using the DPAPI but I'm having trouble with the entropy parameter. Is there any way to generate an entropy to consistently use for the DPAPI functions ...

In this question the OP implies that he wants to base the blog system he is developing on automatic creation of .aspx files, one for each new blog entry. In my answer to his question (which is related to something else), I told him that I would discourage him from using such an approach, but without giving any real reasons. He is now wan...

There are plenty of projects out there that assist developers in posting things to Twitter; the one I can think of off the top of my head is Twitterizer. Are there any projects for posting to StatusNet? Given that StatusNet implements an API very similar to Twitter, I could probably modify/extend Twitterizer to do just that. However, ...
I am loading an html page into a WebBrowser object in a VB.NET Windows Forms application. The user may make changes to textboxes, dropdowns, etc. on the HTML page displayed in the browser. I want the ability to save the current context to a .pdf file on the local HD. I am able to print using WebBrowser.Print(), which shows the current...
I have a user control that contains a collection of controls to be reused for presenting data on the UI. I've attempted implementing a "pop-out" option that will re-parent the control from another container on the form (a Panel, for example), create a new tab page, and then add the control to the tab page. Unfortunately, when the contr...
I am trying to read in the pixel data from an image file as a byte[], for in-memory storage. (The byte array will later be fed to a bitmap image object, but I want the data in memory so that there's no I/O holdup.) This is what I'm currently doing: private byte[] GetImageBytes(Uri imageUri) { //arraySize and stride previously de...
I have a list of objects and I need to find an object as quickly as possible (by it's name property). What data-structure should I use? I know I can use a Dictionary, but there wont ever be more than 10 items in the list, and if I remember correctly the dictionary is implemented as an array if the collection contains 10 items or less. T...

(The package creates files that are then transferred by my application to the client machine.) I have included the "Microsoft DTSPackage Object Library" COM reference in the application, but still ge...
