• Visual Studio Express Editions File System Tree View and Folder Contents

  I am trying to develop a program like Windows Explorer.  I have searched the forum a little and really have not gotten very many answers that I thought have 100% answered this.  I do not know how to display file structure.  I would like to be able to maniulate files in the Folder contents pane and navigate with the Tree View pane.  Anyone have any good links or source   Thanks.

• SQL Server Zero converted to null

  I have restore a SQL Server 2000 database in SQL Server 2005. I have a web aplication that uses dll to talk to the database using ODBC - SQL Native Cliente provider. I have a table with a key integer not null. The first element of my table has a key = 0. When the asp page recive the record set the value of the key field is null, why If i use the query directly in the SQL Server the value of the key is 0. Please help. Hi, thats really strange. Check your query in your frontend if you really did not request the second value. The SNAC does not rewrite queries on his own, there must be a difference in the queries. HTH, Jens K.

• .NET Development Overridden properties and Xml Serialization Question

  I've got a situation where I want an overridden property in a derived class to use a different xml element tag than the base class uses. Actually, that is my entire reason for overriding in the derived class and I'm getting the following error: Member '.ContentId' hides inherited member 'MediaInfo.ContentId', but has different custom attributes. The funny thing is that this is presented as an error, when it is actually a perfect description of the behavior I desire. Is there any way to achieve this or is this an inherant limitation of the Xml serializer Code sample below: class A{ [System.Xml.Serialization. XmlElementAttribute ( "content-id" )] public string ContentId {....} } class B : A{ [Sys ...Show All

• Visual C++ Best practices: marking threads as answered

  Just a friendly reminder to make sure you mark threads as answered if 1. you are reasonably certain that the thread has been answered, or at least the original poster is getting sufficient attention, 2. the thread has gone stale, or 3. the post has been deemed off-topic.  The reason for this is to encourage others to read a thread that still needs resolution. Thanks. Brian   My opinion is just my opinion, so please don't think you must do what I say. Even if I say you must, I mean that as a suggestion.

Is it possible to host the WinForms ReportViewer control in WPF context I have learned that WinForms controls can be hosted using WinFormsHost, but I wasn't sure about ReportViewer control sicne it's not really part of the .Net framework (I could be wrong about this).

• Software Development for Windows Vista COM interop call fails from Windows Service

  Hi! I have a Windows Service that makes a COM interop call to a VB6 COM object.

• Commerce Server Commerce Server Deployment Nightmare

  With my development about 1/2 done, I have been interested in moving what I have to a test environment, and I am having a horrible time. Here is the problem: The web server that will host the Commerce Server application will be on a separate server than the databases. I installed Commerce Server on the web server without event. I also was able to configure the databases so that the MSCS_Admin and CatalogScratch databases were created on the right server. Here's where the fairy tale ends however. The installation instructions say to then unpack the CSharpSite pup package. Well, since I don't want to use the default ootb site, I instead unpacked MY packaged site from my development machine. Again, the databases were created on the correc ...Show All

• Visual Basic Adding image to Project (and retrieve them in debug mode)

  Hi, I have a picturebox where I show a gif file. If I add the image using the 'image' property in the Properties tab, everything is ok and I see the image when I debug. However, I want the image to change depending on various actions from the user. Therefore I do like this : PictureBox1.ImageLocation = Application.StartupPath & "picture01.gif" When I run in debug mode it can't find the image, even though I have added the gif in my project. Why doesn't the debugger copy the image to the debug folder If I manually copy picture01.gif to the debug folder, then it is displayed ok. How to let the debugger 'copy' these pictures (and folders if that's needed) into to the debug folder I found ...Show All
