• Visual C# How to determine file reading progress

  I am using streamreader to read lines of text from a file. I would like to indicate on a progress bar the status of the reading process. What would be the best way to determine where I am within the file so that I could divide this number by the filename.Length member to display in my statusBar I'm having trouble finding the right method for indicating where the file pointer is... You don't use Control.Invoke to read the file. You use a different thread to read the file, then Control.Invoke from that other thread to update the UI.

• Visual C# Thread safe wrapper around generic dictionary

  Could someone give me a pointer as to how I might implement a thread safe wrapper around a genric dictionary   I've written thread-safe dictionaries in C# 1.x by inheriting from the DictionaryBase but I'm a bit stumped as to how to acheive this using Generics. TIA Danny Tobin, thanks for the feedback.  In the absence of any other guidance over the last month I implemented the first option, the 'sub'-class.  Not elegant but it works.  I am very much a threading newbie so to be honest the discussions you've been having with Tag have largely gone over my head. All I'm doing in my class is usi ...Show All

  hi all,   I am experimenting adding WPF controls to an existing MFC app.  Everything seems to work fine except that everytime i make changes to the WPF control xaml, the hole MFC app recompile itself.  I looked at the sample app in the handon lab, and it does the same thing.  Is there a way to get around this jz I am not familiar with the code of the hands on lab.

• Visual C# INullableValue removed from .NET 2.0 RTM??

  I began the process of upgrading one of our Beta2 applications to run under the 2.0 RTM and the compiler is complaining that INullableValue cannot be found in the System namespace. Using the object browser I can verify that there isn't a INullableValue interface defined in the mscorlib assembly version 2.0.50727. Was it intentionally removed If so, why has the documentation not been updated to reflect that change The code I am trying to use has this form: if ( value is INullableValue && ( (INullableValue) value ).HasValue == false ) {    //do something } else if ( value == null ) {    //d ...Show All

• SQL Server Database restores using Enterprise Manager

  Good afternoon. I am using MS SQL 2K and was wondering if it is possible to restore multiple back-up files (database and transaction logs) to a database, if you haven't created a back-up set, using Enterprise Manager. I know that you can write T-SQL to first restore the back-up file and each of the transaction log files, except the last one, with the option of norecovery, and then the last transaction log file, with recovery. Any help would be greatly appreciated. Thank you. Chris That the way, restoring the database files one by one. HTH, Jens Suessmeyer. --- http://www.sqlserver2005.de --- ...Show All
