• Windows Forms Click Once: Creating .appref-ms manually is not valid

  Hello All, To get around firefox we are sending firefox users .appref-ms files. This is fine. For security reasons the application URL is pointed to a Download.ashx ... allowing dynamic creation and removal of the application for the authenticated user. This all works fine in IE For firefox of course .application extensions don't work because fire wont let you run the .application extension from its real location. Hence the .appref-ms approch. Again this works fine if the .appref-ms is copied from the start menu and sent to someone or downloaded but it appears there are some undocumented elements in the .appref-ms process. Creating a text file with content http://localhost/downloads.ashx user=AB2F11B1B5E96100E3EE1F247EE ...Show All

• Visual C# Interface & Class Discrepancy with Java

  Discrepancy with Java               In java if I have interface with 5 methods & if I am not interested to override all the 5 methods then I can create an abstract class and I can implement only few methods. Later I can inherit the abstract class to my original class to override those abstract methods.               This is the simple way to use the required function from the interface. When I tried the same logic with C# or J# it doesn’t work. I declared a class as abstract and avoid to implement few methods it throwing a compiler error.         &n ...Show All

• Visual Studio 2008 (Pre-release) WPF Application Caching

  Hi, I am looking for a way to cache data in a WPF application. The process works like this: I make a call to a web service, and retrieve customer information. I want to be able to store this information at the application level so that the user has the option of retrieving it from the cache, rather than having to call the web service each time. Before calling the web service, I want to be able to check the cache to see if the information exists. If it does, the information is retrieved from the cache. If it doesn't, then the new infomation is added. I was thinking of doing this using a Dictionary or Hashtable, but I'm not sure how to make this object available at the application scope. Is this a good approach, or is there a ...Show All

• .NET Development Going crazy updating database

  I'm about to go crazy about this. I have a database with a couple of tables. I have inserted all tables into a dataset. The data is modified partially by databound fields and partially by manual adding/deletion/modifying. The problems come when i try to transfer dataset to database. I have tried a shitload of different ways but it won't work. This last time i tried OleDbCommandBuilder mybuilder = new OleDbCommandBuilder(MyAdapter); MyConnection.Open(); DataSet ch = MyDataSet.GetChanges(); MyAdapter.Update(ch, "Currencies"); MyConnection.Close(); where Currencies is a table in my database. I have also tried OleDbCommandBuilder mybuilder = new OleDbCommandBuilder(MyAdapter); MyConnect ...Show All

• .NET Development Detecting a router's external IP

  Hello everybody, I'm just getting started in the realm of networking w/ the .NET framework. I'm coding my app in C#, it's just a simple command line server that will listen for commands from an external client. Right now, I'm just trying to get the server, when started, to print out the local machine's IP. However, I want it to print out the address as seen by computers not on my network. So, instead of 192.168.1.XXX, I want it to give me what a website like http://whatismyipaddress.com/ would return. Thanks in advance! If you have a web server yourself, the easiest way for one of your programs to get its WAN IP address is to do what Aymaneez suggests, but to load the address from your own web server.

• Visual Studio Team System Configuration of TFS

  IS there documentation about best practices or suggestions about how best to configure TFS for a particular development environment. What I am referring to here is a discussion about the use of Team Projects, Areas, and the likes and thigns to consider. For example at my compnay we have a TFS installed and will be used by three departments. Each department has about 5 applications that will be managed with TFS and we are wondering what the best approach is. Is each department a Team Project or is each application regardless of department a Team Project. Questions like this.

• SQL Server Importing Excel "Reports"

  I'm trying to import data which from Excel which has been "prettied up" to make it readable to users. The report has a fixed number of columns and the data itself is well structured, but there are blank lines etc. The problem I'm having is unless the first row of the spreadsheet contains or headers, SSIS fails with error "External table is not in the expected format." and the exception below is thrown. So I thought I'd be clever and create a template spreadsheet with the same number of columns and set the first row to strings - I made all columns DT_WSTR thinking I could extract the numeric and datetime data from the actual rows which contain data and convert using a script. But SSIS simply ignores the numeric ...Show All
