  Hi, After attaching an XML schema to word 2007 document, I would like to generate an XSLT file from it. In Word 2003, I can do it by running WML2XSLT.exe tool on doc.xml file.

I run it through the command line on my production server the following way: D:\test\CMS_MoveContentToLive>dtexec /f D:\test\CMS_MoveContentToLive\CMSMoveIte mToLive.dtsx -de The -de option is because i changed the default security protection level of the package as BOL says that for the default protection level (EncryptAllWithUserKey): "Only the user who created or exported the package can open the package in SSIS Designer or run the package by using the dtexec command prompt utility." The problem is that the package does not run successfully and vomits a ...Show All

• SQL Server Mapping Variables to Resultsets

  Is there a problem mapping variables to resultsets with a bigint as datatype I've tried using int64, and others, but all fail except for object datatype. I cant use object datatype because i wont be able to use it as a derived column. Any ideas here Big integers are returned now as strings.

• .NET Development XmlSerializer or custom serialization?

  Hi! I'm currently not sure whether I should use XmlSerializer to save the properties of a class to an xml file or if should just write the file manually with XmlTextWriter. The problem hereby lies in the speed of deserialization. My program will load an undefined number of such files and create instances of the corresponding class at startup. Thus the deserialization operation should take as few time as possible, even if that means writing more code. If I have a class named Employee with the properties Name, Address, Age, and Salary I'd deserialize it with an XmlReader as follows: while (reader.Read()) {     if (reader. ...Show All

These collection classes all have the same property members that I have overriden,, such as Add, Remove (Overloaded), this, etc etc. I may be going down the wrong route with Generic's here, but could I have one Collection Class with these Property Methods that holds generic Types, and then do some running conversion to the appropriate types Am I going down the right path with this Tryst The idea behind ...Show All
