• Smart Device Development Read specific line from a file?

  Hi, Is there a method to read a specific line of a text file The StreamReader class does not seem to have a method to do so. The Peek method isn't what I'm looking for either. Would appreciate your help. Thanks. Will threading help If you know in advance what is the file to be processed, you can start a thread to index it first. I did a simple test program, and indeed, with indexing, reading any line is extremely fast. In my program, if the user wants to read a line that has been indexed, the result is displayed immediately, otherwise, a timer is started to repeatedly check if the line has been indexed.

• .NET Development Limit on number of DIME attachments?

  Is there a limit on number of DIME attachments that can be attached to a response or request Soap Context Object ~Srilatha The RequestSoapContext and ResponseSoapContext objects both have the Attachments property which are of an unbound collection type. There is no limit to the number of file attachments you can add, however you may start to run into message/request size limits. You may also have to consider connection timeouts as the connection could get closed underneath you while uploading the files... in that case you'll either get an Underlying Connection was closed error, some other WebException& ...Show All

• .NET Development Is gacutil.exe redistributable

  I am producing a bespoke software system in C#/C++ for Windows 2000 that uses the Office XP Primary Interop Assemblies (PIAs) to talk to MS Access. I am required to provide our customer with both the executable system and full soure code on CD for full system installation & recovery as well as post-development by the customer. I believe the Office XP PIAs are redistributable so we should be allowed to include them on our delivery CD. However, in order to install them, we need to use gacutil.exe (Global Assembly Cache Utility) which come with the .NET Framework 2.0 SDK but this does not appear to be redistributable. The ...Show All

• SQL Server Optional Arguments in SQLCLR stored procs

  I expected Optional ByRef nArg as Integer=123 to setup a sp arg with a default value of 123. Doesn't look like it does. Anybody know what I'm doing wrong Also, I can't write a function with a return using AS System.Int32. There is no RETURN sp arg. Both situations compile/deploy without error. Turnbuckle wrote: I was hoping a function that is launched as a stored proc would create a return. Appears not to, so I'll probably end up altering the proc. I don't understand what you mean.
