• .NET Development C# 2005 Web Service question

  Hello everyone, I'm fairly new to C# and I have a question about return types. Specifically, I have a web method returning a dataset, but I need to return an error message if there is one. How is this done in C# Thanks! Robert Lewis >> Give the method an "out" parameter, being a string to indicate an error message and return null if there is an error and set the "out" parameter to the error message you want. << Does an out parameter work on a web service Since the parameters & response are being marshalled through HTTP, I'd figure each would only go one way. >> Alternatively you could make a global variable in the webservice which you can access di ...Show All

• Visual C# Converting System.Type to OleDbType

  I can`t find class and methods that convert System.Type to any of dbtypes(OleDbType or SQLType). I know for the mapping tables, but I need conversion methods for all data providers(OleDb, SqlClient, ODBC) . It is not difficult to write that by your own, but I can`t belive that it is not alredy written by Microsoft. Exactly! That`s it, that is one solution. Just, I wanted to make software component that could be used in any situation, independent of the database (I just create dataset through the wizard, and then use one generic tableadapter that works with all datatables in dataset. Adapter creates statements dynamically based on datatable). That means avoiding stored procedures and implementing update, ...Show All

• Visual Studio Debug a DLL used by two programs

  I hope this is the correct forum. I have two program that use the same DLL. I want to launch both program and debug one of the programs as it uses this DLL. I want a single copy of the DLL in memory so that when I debug into the DLL I can see the footprints both program left behind. How do I setup Visual Studio 2005 to do this Jeff Stout When a program loads a DLL, that executable is mapped to that program's process space. Another process that uses the same DLL will map the code into it's OWN process space. The OS makes sure there's only one copy of it actually loaded into memory, but as far as the programs' are concerned, they each think they are the only user of it. If you can provide mo ...Show All

• SQL Server Access protection on deployed SQL Server

  How can we control the accesses to a SQL Server that has been deployed on customer site Basically, we do not want user to log in the database server, even as sa, except through our application. Any recommendation Thanks, Xiaodoudou In your case, I assume you have no control over the customer site - if that's the case, then you cannot enforce access only through your application.

• Software Development for Windows Vista How do I get a list of installed security updates?

  I am having trouble getting a list of installed security updates on my Vista Beta 2 machine. On Windows XP I just enumerated the uninstall key to get a list of Installed Applications and worked out which ones were security updates. On Vista the updates dont seem to be listed under the uninstall key any more, I guess they have been relocated. Any ideas how I can get a list of installed updates programatically I am using C++ Visual Studio 6.

• SQL Server programmatically setting package variables in job step command line

  We are trying to start a server job running an SSIS package and supply some parameters to the package when we start the job using SMO. What we have now is this: string cmdLine = job.JobSteps[0].Command; cmdLine += @" /SET \Package\GetGroupRatingYear_Id.Variables[User::RatingId].Value;1"; cmdLine += @" /SET \Package\GetGroupRatingYear_Id.Variables[User::GroupId].Value;1"; cmdLine += " /SET \\Package.Variables[User::period].Value;\"" + periodEndDate + "\""; job.JobSteps[0].Command = cmdLine; job.Start(); It appears that when the job is run, the modified command line is not used.

  Hi I'm trying to create an album-viewer of all my music albums. To this I'm using a ListBox with Orientation ="Horizontal" - this is all fine, and I can see my albums. But my issue is, that I want to center the item I just pressed. How can I do that Is there an alternative to ListBox which is better to use for this purpose I'm not clear on what you're trying to do. When you say that the ListBox's Orientation="Horizontal" do you mean that its ItemsPanel's Orientation is Horizontal What do you mean by saying that the selected item should be "centered" Centered vertically Horizontally ...Show All
