• Visual Studio 2008 (Pre-release) Rolebased Security & controls

  Hello, For my WPF application, I need to use rolebased security to: a) Disable buttons b) Make controls readonly or read/write I'm planning to use an access matrix for each role. Each control has a boolean that indicates if it is enabled or if it is readonly. It just seems like a lot of work, and lot of binding code (in xaml-binding and cs-properties). aya-yaya... Is there a way out of this Is there a better approach Thanks Houman Josh, I'm going to spend some time playing with this suggestion. Sounds good to me... If I'm not mistaken this way all the enable/disable logic/lookup can happen in the class that wraps the dependency property I haven't used dependency propertie ...Show All

• .NET Development Copying/Cloning question

  A third-party grid control I am using does not appear to support Cloning/Copying, nor does its' ColumnCollection which is what I really want to get at. Question is do I need to custom-implement some way of copying/cloning what I want or is there anything I might be overlooking here Thanks! I really appreciate you writing out that extremely detailed answer. I just need the column names and their visibility (for now) and to feed those back to the source grid, so I'll go with a custom struct for now. ...Show All

• SQL Server SQL Native Client Configuration or Remote Connections problem

  If I look under SQL native client configuration | Client protocols, I have no entries and no ability to look at the properties of SQL Native client Configuration. Something is missing which I think is related to an error when connecting to my local server. sqlcmd -E -S .\devmain, 1064 I get error : Encryption not support sqlcmd: Error: microsoft SQL native Client : Client unable to establish connection An error has occurred while establish a connection to the server. When connecting to SQL Server 2005, this failure may be caused by the fact that under the default settings SQL Server does not allow remote connections..

• Visual Studio Visual Studio 2005 Addin - How to find all the controls in a webform?

  Hi everyone, I’m the coordinator of project NMVP ( http://www.codeplex.com/nmvp ). It’s a framework to develop MVP architectures. The framework is doing really well, but there’s one task I’d like to automate that is the task of creating a contract for the web form.

• Windows Forms Change default icon on the application's exe file??

  I have been searching for the answer for this problem for a while now. I have been going through the settings without no luck at all. I have found out how to: * change the icon on the application window's left upper corner * set the icon that's showing in add/remove programs dialog * change the icon on a shortcut placed on the users desctop (by adding the icon to the programfolder and then change the shortcut's icon-property to that icon)...

But how do I change the default icon (white with blue border) on the application's exe file that is outputted to the programfolder by the installer project I have added the icon i want to use in app.rc by using the "Resource View"-windo ...Show All

• .NET Development HELP ME!!! Need to update database from dataset bound to a datagridview!!

  Hey guys, I'm still new to C# and have not coded for about 4 years (and that was c++ and I never touched databases or SQL) I have been developing a piece of simple software that uploads a .csv file into a dataset and then binds a datatable from that dataset to a datagridview control. This is fine and works ok. However, once changes are made to the Datagridview (and thus I presume to the datatable in the dataset as its bound to the datagridview), I then want to update the database with the updated datatable. However, when I call the update method for my OdbcDataAdapter object, it tells me that Update requires a valid UpdateCommand when passed DataRow collection with modified rows. I think I understand that in order to update the database ...Show All
