Let's say I have many-to-many relationship (using the ActiveRecord attribute HasAndBelongsToMany) between Posts and Tags (domain object names changed to protect the innocent), and I wanted a method like FindAllPostByTags(IList<Tag> tags) that returns all Posts that have all (not just some of) the Tags in the parameter. Any way I could ac...

If I want to put a form up on SharePoint, is it easier to use InfoPath or build a custom web part in C#? Are there other options that I should consider? What are the requirements and hurdles for each option? ...
It's common knowledge that using System.Diagnostics.Process.Start is the way to launch a url from a C# applicaiton: System.Diagnostics.Process.Start("http://www.mywebsite.com"); However, if this url is invalid the application seems to have no way of knowing that the call failed or why. Is there a better way to launch a web browser? If ...
I have a page in my vb.net web application that needs to toss a bunch of data into a text file and then present it to the user for download. What's the best / most efficient way to build such a text file on a .net web server? Edit: to answer a question down below, this is going to be a download once and then throw-away kind of file. U...

My form receives asynchronous callbacks from another object on random worker threads. I have been passing the data to the main thread (where it can be used to update onscreen controls) using delegates as shown below. Performance is dreadful -- once I reach 500 updates per second, the program completely locks up. My GUI processing itse...

If it helps, I know that the class implements IMyCustomInterface and is from an assembly loaded into the...
Here's the situation. I have a webservice (C# 2.0), which consists of (mainly) a class inheriting from System.Web.Services.WebService. It contains a few methods, which all need to call a method that checks if they're authorized or not. Basically something like this (pardon the architecture, this is purely as an example ;)): public cl...
Is there any setting in Visual Studio 2008 to group/organize tabs? For example, I'd prefer to have all code-behind files open in a tab next to its .aspx page if that page is open and vice versa. Dragging tabs around really kills my productivity. ...
I assume there must be a system and language independent way to just stick the "current" EOL character into a text file, but my MSDN-fu seems to be weak today. Bonus points if there is a way to do this in a web application that will put the correct EOL character for the current client's machine's OS, not the web server's. ...
I use int.MaxValue as a penalty and sometimes I am computing the penalties together. Is there a function or how would you create one with the most grace and efficiency that does that. ie. 50 + 100 = 150 int.Max + 50 = int.Max and not int.Min + 50 ...
I got a program that writes some data to a file using a method like the one below. public void ExportToFile(string filename) { using(FileStream fstream = new FileStream(filename,FileMode.Create)) using (TextWriter writer = new StreamWriter(fstream)) { // try catch block for write permissions writer.Wri...

Based on which radio button is selected I want to display the proper control to the user. The way I'm doing this now is just loading both controls and setting up an OnRadioButtonSelectionChanged() method whic...

Hi, What is a .snk file for? I know it stands for Strongly Named Key, but all explanations of what it is and how it works goes over my head. Is there any simple explanation on how a strongly named key is used and how it works? I'm using this in BizTalk server. ...
I have a ListView which sometimes I need to put around 10000 items in. ListViews don't really handle this well, and they lock up for a couple of seconds while they sort the items and draw them. If you add the items in individually, it's even worse, locking up for nearly a minute. To get around this, I thought I'd try populating the List...
