I have a asp.net web application that creates a Folder on a FTP site, but I need to grant permissions to that folder to some users of the active directory. How can I do that programatically, inside my app when I create the folder? ...
We have an asp.net application that needs to be expanded to notify users when an update occurs. All users need to be notified even if they don't have the asp.net app opened. All notifications must occur at the same time for everyone, so email is not an option. The application will run on a corporate network with standardized client co...
I'm having trouble with solution wide analysis since I upgraded to resharper 4.5. I'm continually getting false negatives, and having resharper report errors with my code that are not there. I find the only way to get rid of the errors is to open each of the reported in error files, find the offending types/classes, open those files an...
I want to run a query to get a string array of distinct "logName" items for a logType. The following works great: Dim stringArray() As String = (From item In dc.Vw_Logs Where item.LogType = [Passed in logType] Select item.LogName Distinct).ToArray() However, this only works when a specific LogType is set. I would like the ...
We have been going through a big memory leak analysis and have found one of the contributing factors has been the non removal of delegates on events causing objects to not be GCed quickly enough (or sometimes forever). Would anyone have any ideas as to how to write a rule in FXCop to ensure that we have delegates are removed from handl...
I'm using the SyndicationFeed class to generate an Atom feed and an Atom10FeedFormatter to serialize it. I'd like to be able to add line breaks between the elements when the file gets written to disk. I realize the feed readers don't care, but when I run my docs through http://feedvalidator.org/ it treats the whole doc as a single line...
I have a Dictionary that contains items and prices. The items are unique but slowly get added and updated through the lifetime of the app (i.e. I don't know the item strings in advance). I would like to bind this structure to a DataGridView so I can show updates on my Form, something like: Dictionary<string, double> _priceData = new Dic...
I am using ThreadStatic variables to store some data, but I am worried that the data I store on the thread will still be there after I am finished with it and release back to the ThreadPool. Do I need to worry about clearing my ThreadStatic variables before I am finished with the thread? Or will the ThreadPool do this for me before "pa...
I wrote a VB.NET windows service and I'd like to know if there is some library or something that will provide me with a very simple mini web server. If my service is running, I'd just like to be able to type, in my browser: http://localhost:1234 And have a status page popup. It will only be one single page and very simple html. Anyone ...
I really hate this error, because it can be so hard to pin point. In this case, I have a page with a user control on it that contains a gridview. When a button is clicked to view one of the records in the gridview, a pop-up window (in the form of a modal dialog) opens allowing the user to edit the fields. Then, when the pop-up is clos...
One solution would be to add a QueryString variable to the url that is a random guid, but that seems a little messy. Is there a setting somewhere that will prevent the browser from displaying a cached version of a page? ...
I have seen the abbreviation WS-*, but I have not been able to figure out what this means, and why is it important? ...
I don't know if i am asking a silly question but I want to know whether Convert.ToBase64String function in .NET returns the same length as it's source byte size or is it different? I wanted to try out the article from MSDN itself How To: Use Forms Authentication with SQL Server 2000 to hash my password but I found out that the function t...
I would like my canvas to automatically resize to the size of its items, so that the ScrollViewer scroll bars have the correct range. Can this be done in XAML? <ScrollViewer HorizontalScrollBarVisibility="Auto" x:Name="_scrollViewer"> <Grid x:Name ="_canvasGrid" Background="Yellow"> <Canvas x:Name="_canvas" HorizontalAlignme...
No matter how I try, I cannot mimic the clean syntax of Rhino Mocks, without declaring a delegate. Example: Expect.Call(service.HelloWorld("Thanks")) Do you have any idea on how to do this? Thanks. ...
I can't seem to get a transparent background for a DataForm in Silverlight 3 beta. The code below is what I am trying but it only makes the background partially transparent. Is there something I can do to fix it? <Grid x:Name="LayoutRoot" Background="Orange"> <Border Background="Blue" Margin="100,0,0,100"/> <Controls:DataForm ...
I have a desktop application which contains an App.config (program.exe.config at release) with clearly visible elements which define my WCF endpoints and WCF implementation. I would ideally like to hide this from the users eyes, from simple hacking, view and change. Should I: - Programmatically create and store my WCF endpoints and b...
I've been working on a .NET application and experiencing a memory error (I'm a java developer that can do other things), I've been thinking about performance. What I'm posting about was not the memory problem. The memory problem just started me thinking. I've repeated a trend in my ASP.NET application that I've used on countless J2EE ap...
Has someone ported the netTiers template set to Visual Studio's T4 templates? Or is there a system of similar scope? Does anyone use T4 in a work environment? What (if any) major differences are there between Codesmith and T4? ...
I want to save my program's DataModel objects to a file, and be able to reload the same object graph again. I want it to be in some flavor of text file, so I can diff it and open it in a text editor. XML would be fine, and seems like a good place to start since .NET has XML serialization built in. But which flavor of XML serialization s...
