• Visual Basic Parsing/extracting multiline fields

  I have a very large sequential file in which each data field is delimited by the same unique string (//, specifically). Each field of data is multiline. I would like to iterate through the file, extracting each field of data for purposes of parsing subfields and recording the offset of each field of data. Unfortunately, I can not identify a method that extracts/parses data fields that span multiple lines. TextFieldParser seems like a nice option, but it seems single line oriented also. I realize I could read each line of the file sequentially and concatenate each line until I reach the delimiter, but I would like a more efficient metho ...Show All

• Visual Studio Team System Project Class Libraries

  We utilize a large number of class library projects within our existing applications for our business logic. Within the Application Designer, it does not seem to allow for Class Library projects, only Web Apps, Web Service Apps, Windows Apps and a Generic App. What should I be using within 2005 Application Designer to create these Class Libraries They are not classes that I would be adding to a given application, they are complete projects. Is that the 'Generic Application' Thanks in advance, Chad The technique Elona described ensures that web service connections you make in referenced class libraries are e ...Show All

• SQL Server DTS in SQL 2005

  Hello, This is kind of a stupid problem. I just installed SQL 2005 Standard and I am trying to use DTS to transform a Access DB to SQL. I am having a tough time finding where that feature is. Is it by default insatlled or is it an add-on Thanks! In SQL 2005 it is no longer called DTS it is known as SSIS(SQL Server Integration Services). You can migrate DTS packages to SSIS or re-build them using the Business Intelligence Development Studio. ...Show All

• Visual C++ C++ name mangling change between 2003 and 2005

  We have a Win32 console DLL that we currently compile with VS C++ 2003, but we need to be able to allow it to be linked to and used by executables compiled with VS C++ 2005. For the most part this works. However, we have a couple of functions that take a std::exception as an argument, and these cannot be used in the 2005 executables because the name mangling is different. In 2003 the mangled name is: foo@@YAXVexception@@@Z and in 2005 it is: foo@@YAXVexception@std@@@Z Does anyone know of any way that we could control the way in which the names are mangled either in 2003 or 2005 to allow the function compiled by 2003 to be ca ...Show All

• Visual Studio "Start Debugging" vs "Start without Debugging" speed in VS2005

  I experienced extremely slow performance in VS2005, when I "Start Debugging" an application which uses System.Drawing.Bitmap (might be anything that uses interop, but that's just my wild guess). Everything is fast if I "Start withoug Debugging" and it does not matter if I compile a release or a debug version. Please check this little piece of code: namespace ConsoleApplication1 { class Program { static void Main( string [] args) { System.Drawing.Bitmap b = new System.Drawing.Bitmap(1000, 1000); int bla = 0; for ( int x = 0; x < 1000000; ++x) bla = bla + b.Width; } } }   It demonstrates the difference in speed nicely and ...Show All

• Windows Forms Any build-in feature to memorize datagridview setting?

  My winform application has a datagridview which let users to set columns' width and height freely. Is there any build-in functionality to store the setting of the datagridview(such as column's width, row's height .etc) so that the users don't need to set them everytime the application is started Thanks. Hello. There isn't anything built-in but I don't think this would be very difficult to create. You would realy just need to persist the DisplayIndex, Width, and Height of each column into something like an XML file in IsolatedStorage (so that it is per-user rather than per machine). There is a good example of this here   ...Show All

• .NET Development XML serializer does not serialize values of properties if value contains only spaces

  Hi all, I have a field of type string in a type that is serialized to XML. If the field value is just one space, the resulting XML is this: <FieldName /> This creates an issue with deserializing, because in the context of the application, " " is not equal to string.Empty. I've looked for options on the serializer, and for serialization attributes that would control this behavior, but I could not find any. Any help is appreciated. SA.
