• .NET Development XSD.exe generation of <remarks>

  When one uses xsd.exe to generate class files from an XSD, it inserts empty <remarks> comments above each member. These do not seem to be persisted back when one uses xsd.exe to generate an XSD from the generated class. Do these sections get filled from a particular attribute or element in the XSD If not then why are they there I think the main reason most code generaters (xsd.exe, wsdl.exe ect.) make empty <remarks/> is to avoid warnings from the compiler about missing documentation. For that reason it makes sense that it isn't persisted back to the XSD. ...Show All

• .NET Development Update requires a valid UpdateCommand when passed DataRow collection with modified rows

  I m coding with VB.Net. I have a datagrid on my form with a dataset as its datasource. The dataset contains rows from a joined two tables: Feature table and Price table. Feature table contains the customers'features. It has the ID of the features, the date the feature was added, the expiry date, the employee who added it....

• SQL Server Is there anyway to do SUM on join table?

  I would like to start using SQL Server CE rather than SQLite for an application I am developing, due to it's replication support for SQL Server however there appears to be a gaping hole in it that means I can't even consider it. Specifically to do with aggregates against detail tables. Is there any way to do the equivalent of the following in SQL using SQL Server CE SELECT [Customer_Id], [Customer_name], COALESCE([OT].[Count_Orders],0) [CountOrders], COALESCE([OT].[Sum_Value],0) [OrderValue] FROM [Customers] LEFT OUTER JOIN (SELECT .[Customer_Id], COUNT(*) [Count_Orders], SUM( .[Order_Value]) [Sum_Value] FROM [Orders] GROUP BY .[Customer_Id]) [OT] ON [OT].[Customer_Id] = [Customers].[Customer_Id]); Any help would be most welcome Adrian ...Show All

Exsample: <Old data size:1gb><NewData size:500mb><Old data size:5gb> how i can do this Thanks are you trying to do a virtual file system I think you should do a VFS Stream reader/writer and use an index at the start of your big file. then with the writer you write chunks and upodate the index, with the reader read the index to find which chunks are used by your files inside, and ultimately a defrag tool to write all the chunks in the right order. ...Show All

• Visual C++ C++/CLI problems/issues

  I have some questions on C++/CLI issue. Let me explain my situation: I have an existing native COM dll that contains my logic. It has been tested and works fine with native C++ client using CoCreateInstance. I would like to add a new logic and notice that BCL has a class that I can use. So I add a new source file and header which I compile with /clr since I need to use one of BCL classes (actually, at this point, it is just an empty shell). When I tried to CoCreateInstance in my native client, it couldn’t create. But if I go back to my COM dll project and take out the /clr in my new source file, it works fine. After some debugging, I found out the problem and have been able to fix the issue. However, I would like to get more detai ...Show All

  Someone told me that if I deploy my project to my xbox 360 along with the xna framework it would void my warrenty. Is this true Unless by "deploy" you mean "take hard drive out and copy your project onto it directly". No need to worry. Btw, you deploy your project onto the Xbox using Game Studio Express via the network. The launcher has everything necessary to run your compiled project. No need to send the "XNA framework" to your box. ...Show All

• Windows Forms BindingSource: when to add form data to underlying list

  I have a BindingSource with an underlying list assigned as a datasource. I create the list from a flat file using the list contructor and then assign the list to my BindingSource's DataSource property. The BindingSource is assigned to a BindingNavigator. I use the Position Changed event to move data from the list to the form for display. This works perfectly for the MoveNext, MovePrevious, MoveFirst, and MoveLast events. Now I am ready to add a new record. My first thought was to use the AddNew event; however, the AddNew event is called prior to having entered the new data into the form. So, what is the proper event to catch for moving the data from the form to the empty record (which is created by the default AddNew processing) ...Show All

• Software Development for Windows Vista elevate(UAC) activeX in vista?

  Hi, We have an activeX dll which does file/registry writing and spawns childs process which also seems to need elevated UAC access. I have searched net, and found you could elevate executables by embeding 'manifest' file into the executables. I've also found analyzing tool 'standard user analyzer' for exe files, but it won't help me with activeX What should I do for activeX to be able to perform restricted writing and such One solution I found is that I could run IE as 'Run as administrator', and the activeX control could perform all neccessary actions. However, I don't want the user of the activeX to do that. Any help will be much appreciated. Thanks On Windows Vista, a process contains a single token an ...Show All
