• Visual C# How to make a treeview control like a FolderBrowserDialog that can view files within those folders

  hi How to make a treeview control like a FolderBrowserDialog that can view files within those folders so that the user can select the file. Here is a small piece of code modified from your question some time ago: protected void AppendDirectoriesToTreeNode( TreeNode node, string root ) { DirectoryInfo rootDir = new DirectoryInfo( root ); foreach ( DirectoryInfo subDir in rootDir.GetDirectories() ) { TreeNode subdirNode = new TreeNode( subDir.Name ); AppendDirectoriesToTreeNode( subdirNode, subDir.FullName ); foreach ( FileInfo fileInfo in subDir.GetFiles() ) { subdirNode.Nodes.Add( fileInfo.Name ); } node.Nodes.Add( subdirNode ); } }   ...Show All

• Windows Forms Best Component for the job?

  Hi, I'm not sure if the header is the right one, so if it's confusing, I'm sorry. I come from Sun's Java world and don't know my way around the GUI programming in C# yet. When I want to display a tabular data structure in Java, I use the JTable object, which is suitable for any type of tabular data, and can be provided with a 2 dimensional array of objects that can be placed in the table using the toString() method, regardless of the data source that is used for that table. I'm trying to do something similar in c#, and I'm having trouble working with the DataGridView, which is simple only if you connect it to a datasource. I have a TCP server program written in c# that needs to display data about connected clients. I need to ...Show All

• Visual Studio 2008 (Pre-release) License to deploy June CTP WCF in a server

  Hi Is there necessary to request a special license to deploy June CTP in a producction server Thanks in advance Javier Hello Javier, I am afraid that we have not provided a Go-Live agreement for the June CTP release and do not recommend using the release in a production environment. If you need to deploy your release into production, use the Beta 2 release (after signing the supplemental use agreement), or wait until the next production quality preview release of the .NET Framework 3.0 that will ship with the next major Windows Vista project release. Thanks, - Craig McLuckie ...Show All

• Visual Studio 2008 (Pre-release) Help: RC1 ListView Memory Leak

  I've got a memory leak problem with the ListView. I just have a long list of items that I put in a list with 2 GridViewColumns, and as I scroll up and down the list the memory goes up and up and up, until I eventually run out of memory on my machine if I do it long enough. I find it hard to believe that there's a problem like this with list view, so I'm wondering what I've done wrong. I'm running RC1 on Windows XP x64. I've done a real simple example. The code is below. You can run an XBAP version from here: http://150.101.100.238/~john/LeakyList/LeakyListXBAP.xbap In task manager, watch PresentationHost.exe Mem Usage grow as you scroll the scrollbar up and down. Press "Collect Garbage" and the Mem Usage won't go down ...Show All

• .NET Development Sorting of datasource

  I have a datalistview which is bind to a datasource. May I know which is a better mechanism in order for user to click on the header to sort the display..using the bind source sort property or the data list view Regards Alu I can't speak to whether one method is "better" in terms of performance or not, but I personally have standardised all our projects on using the BindingSource methods for everything, simply because they seem to work more often with less fuss, and because they're the same regardless of the underlying data source, be it a DataTable or a strongly-typed collection of business objects (which doesn't provide a DataView). ...Show All

• Visual Studio 2008 (Pre-release) Support for Group By, Having etc

  How sophisticated are the query capabilities for LINQ. Can a SELECT includes Group Bys, Aggregate Functions, Having Clauses. I have a sophisticated query which runs within the MS Access query designer, but running the same query using .NET OleDb provider results in an error. The query uses joins to selects which have group by and aggregate functions in them. The error message says there is an error in the Syntax after the From clause. So I'm thinking to return result sets back to VB.NET and use LINQ to further process the data into the final result set. The other alternative is use a lot more code to massage the data into the final result set which is going to be nasty. The VB LINQ support in ...Show All

• SQL Server Server Broker Contract talking to Multiple Computers

  Hello, I solved the previous issue I had and now need to find out how to make it so I have Service Broker running on one machine and the services running on another machine. I mean you can set a connection string to post a message to the service broker but then it will need to respond and the connection string in the method called does not allow you to put a server in the connection string. The other issue is because the stored procedure calls the method in your code based on a namespace and then a method but does not specify a server. I am sure a way exists but am not familiar with it. This is the last piece of the architecture I need to work out before I finish designing the system. Thanks, Scott Allison... Hi Scott, If yo ...Show All

• Visual Basic Setup Produced By "Build, Publish" Gives Error After I Uninstalled VB With CD And 'Removed' All Installation CD Programs

  Hello, I created a setup file from my application. I did this because I want to put my application on other PCs without installing Visual Basic. I basically want to just run the applicatoin on other PCs. What I did to create the setup file was within VB I clicked "Build" then "Publish." I then wanted to test the setup file on my PC, so I removed everything given to me by the VB installation CD! So, I uninstalled VB using the installation CD. But, I also had to go to the control panel to remove some of the programs that the installation CD gave me. I did this because the uninstall via the CD left things on my system that the installation CD gave me. When I was done, the control panel, remove programs listing ...Show All

  Having an intermittent problem printing To: From: CC: Subject: Attachments: headers on emails. Usually happens with larger emails or emails with large attachments or emails that have been replied to or forwarded from other people. Have installed Generic/text printer and sent the email to this printer but sometimes the headers are still missing even printing this way. I have if I open the offending email and highlight just one or two words in the text of the email eg Dear John and then print the email using my HP printer (not as text on Generic printer) - the headers then print and so does the selected words.
