• .NET Development unzipping files in a ZIP file

  I need to read in a ZIP file (WinZIP file) and write out the files contained to a folder, can I use System.IO.Compression I've looked at the deflate stream method, and this looks easy enough to decompress to memory, but how do I write out the files from this point thanks Not sure if the compression namespace supports ZIP Compression or not, but you could try this out: http://www.icsharpcode.net/OpenSource/SharpZipLib/ I've been using it since the 1.1 framework and it works rather well. Thanks Wayne ...Show All

• Visual Studio VS2005b2 automatic attribute code generation

  Hi there! I'm writing my own C# component to be used with the Windows Forms Designer. This component has a DesignerSerializer attached. Within my CodeDomSerializer I would like to generate additional attributes that get noted infront of some form controls. Like this: [My.ActionSourceAttribute("APP17", "New.Action", "")] private System.Windows.Forms.Button button1; I really could manage all that to get the attribute generated at the right place. My problem is that after inserting the attribute by using DTE, it's no longer possible to add new controls in the Designer. To be more precise: One still can add a control using the Designer b ...Show All

• Visual Studio Express Editions Reconfiguring dataset with Access database

  I have a database created with Access. My question is if I make changes to the database within Access what is the proper method of reconfiguring the dataset in the VB editor so that the changes are seen. As an example I created a Users table in Access and then added this datasource to my VB project. I then went back and added a column to the table. What is the proper method of resetting the dataset in the VB editor. Thanks. Because of these issues... I never use these features in VS2005. I read a table in and I use enumerated offsets... the enumeration might look like this: Public Enum DataR ...Show All

• SQL Server Add a variable from custom component

  Hi I am writing a custom transformation component that utilises a user variable. Before using the variable at run time I am checking that the variable exists, but it would be nice to be able to add it if it does not. I cannot find any documentation on the subject, though I can see that the Variables class is derived from a ReadOnlyCollectionBase. Is there a way to add a user variable with package scope from a custom component, either at run time or design time Thanks . . . Ed ...Show All

• SQL Server Incremental loading

  Hi Friends please let me know how can we incrementally load a destination table with source table. bearing in mind that we need to track that there are no duplicates in the destination table. I need to load only changed or new data in the final load. Please give me some examples also. I am tryin this from last 2 days as I am totally new to SSIS. Hi, First off: do you have a column on your source data that indicates that a row is new or changed If you do, then you can select from your source based on that column, using parameterised queries. This might be the case with, for example, an orders_table where the data on the row change ...Show All

• Windows Forms How to show a different text for bool

  Hi, is there a simple way to display a different text on a bool-bound text. Assume I have an app with a label showing some bool value from an SQL-Table. This shows True or False - what I want is to show (for an example) Yes / No, or 1 / 0 on "Out off office" / "In the office". Another "problem" is that I sometimes want to bind reverse. So for an example I want to hide a button if some expression is true. The other way is simple - I bind the Visible attribute to the bool - but what if this is different. Or what if I want to enable when a textfield has a certain value In ASP.NET I would write something like Attr="<%# Eval("F ...Show All

• SQL Server DCOM error

  I just installed sql server 2005 on a windows 2003 server.  I chose the option to install but do not configure.  After restarting, I used the Reporting SErvices Configuration Manager and it all looks ok.  When I browse to //localhost/reports I get a rs page with the message of: The request failed with HTTP status 400: Bad Request. One slightly unusual thing is SQL Server 2005 was installed as a named instance ("(local)\SQL2K5") - the server's default instance is a sql 2000 installation, which had RS installed and running.  Before configuring RS for 2k5, I deleted the VDs for Reports and ReportServer ...Show All
