问题 How can I use Sonar to display results of the output produced by FxCop. I used FxCop to run static code analysis on .NET Project and FxCop generate the result report in an XML format. Can I use Sonar to take this XML file an input and display the output with it? How can this be done? I am looking for an open source dash board tool to present the output the result produced by FxCop to the end user. 回答1: Sonar has a C# plug-in, documented here: http://docs.codehaus.org/display/SONAR/C-Sharp

问题 Ok I was a little unsure on how best name this problem :) But assume this scenarion, you're going out and fetching some webpage (with various urls) and caching it locally. The cache part is pretty easy to solve even with multiple threads. However, imagine that one thread starts fetching an url, and a couple of milliseconds later another want to get the same url. Is there any good pattern for making the seconds thread's method wait on the first one to fetch the page , insert it into the cache

问题 I have been trying to extract the Windows login password hint for Windows 7 programmatically and I came to know it can be retrieved from the following location in the registry HKLM\SAM\SAM\Domains\Account\Users\"userkey"\UserPasswordHint However, I am not able to figure out is there any way to find out userkey for the currently logged-on user programmatically? 回答1: If you can get the current user name, it's quite easy, using the same registry tree. Take a look in HKLM\SAM\SAM\Domains\Account

问题 I just found, web.config with below settings in all the environments including prod. <machineKey validationKey="AutoGenerate,IsolateApps" decryptionKey="AutoGenerate,IsolateApps" validation="SHA1" decryption="Auto" /> Now, application is going to start using with load balancing. Would it create problem as its not using static machine keys ? If I change this key now to static validaitnKey and static decrptionKey then it creates another problem for already protected keys unable to decrypt.

问题 I have some data in a database that I read out with SqlDataReader . I want to put these in a HTML table in my ASP.NET site, but I can't figure out how to do so. 回答1: You can use a gridview. It is an asp.net control which you just bind your datareader to your gridview, and it will display every row that is returned from your database as an html table row. You can even combine two or more columns, and add pictures or links instead of just displaying the data with a templated row. Google it and
