When user enters a wrong value, I write that valid event return false.

• Windows Forms OracleClient with Clickonce Deployment

  I am trying to deploy an application using Clickonce. I previously was using OleDbConnection to connect to an oracle database. However i would like to use the System.Data.OracleClient namespace instead. Upon publishing the application the users get an error when they try to connect to the database. Do i have to install the oracle connectivity files manually on the user's computer Is there a way to distribute the needed files as prerequisites Thanks for your help. In your case I think you just have to install the oracle client software on the client. In the end I used OleDb instead of Oracle to get past my problem. ...Show All

• Visual Studio Team System Is there any way I can disallow regular user to delete solution projects from TFS Version Control?

  I would like my regular developer group to have rights to read, check out, check in and lock the files from TFS Version Control, but I don’t want this regular group to have right to delete the solution projects from TFS Version Control. It looks like to me that Source Control Explorer does not provide the interface to disable project “delete” menu. You're correct, there is no separate 'delete' permission. The only way to stop regular developers from deleting *.sln/*.proj files is to remove the PendChange and/or Checkin permissions on those files...but if you do that, they won't be able to make any changes to them at all. ...Show All

• .NET Development Pragmatics of using IDbComand for direct manipulation of sql statements vs DataTable,DataSet and DataView.

  I have a few WindowForm apps which work with my own database where only i have access to. I am doing daily updates where less than 1% of the main table affected and weekend update where I truncate 2 main tables, drop their indexes, completely reload them and rebuild indexes. Naturally I am directly manipulating SqlComand.Text and using SqlComand. ExecuteNonQuery(), SqlComand.Execute Scalar(), SqlComand.Execute Reader(). Does it make sense to use DataTable,DataSet and DataView only in case of small datasets with relatively insignificant updates with multiple users accesses You might want to check out this article for some recommendation of using DataSet: http://msdn2.microsoft.com/en-us/library/8fxztkff.aspx ...Show All

• .NET Development How to call a legacy COM collection by IEnumerable interface

  I have one legacy COM, after I imported it into one C# project, it expose three function: _NewEnum, item, Count Now I can not walk through its items by foreach( ... in ... ) clause, it seems that _NewEnum function returns one " EnumeratorViewOfEnumVariant " object instead of IEnumerable instance object.

• Game Technologies: DirectX, XNA, XACT, etc. debug drawing

  hrmm how are people handling not being able to draw lines Previously i've extensively used line drawing (in opengl at least) for debugging purposes, but now dx10 is all shader driven i cant do this can i what methods are you using for debug drawing currently i load up the opengl version of my engine to see debugging then load up the dx10 version to see what it looks like under dx10, but this is annoying :-/ I am not sure about what API feature you are talking here. Line drawing is still supported as primitive topology ( D3D10_PRIMITIVE_TOPOLOGY_LINELIST and D3D10_PRIMITIVE_TOPOLOGY_LINESTRIP) If you want to see the wireframe of your objects you have to create a second set of rasterizer sta ...Show All
