• Visual Studio Unable to overwrite a corrupted data file in VSS 6.0

  Hi, There is a corrupted file in ..VSS\Project\data\b\ folder - file name "bwibaaaa.a".  I tried to replace this file from a backup.  It came up with a message "Cannot copy bwibaaaa:  The file or directory is corrupted and unreadable." I'm doesn't allow me to rename or delete this file either.  The same above message appears when I do that. Please help! Thanks, -Wei It sounds like you may have a corrupted disk if you get the message "Cannot copy bwibaaaa:  The file or directory is corrupted and unreadable." when you attempt to overwrite the file from WindowsExplorer. You should run a disk check (either in command like "chkdsk /F C:\") or in WindowsExplorer select ...Show All

• SQL Server connection string error

  OK - I have seen lots posted on this, but the behavior is very strange, and I am trying to understand: I am using Visual Basic 2003 with SQLEXPRESS 2005 to connect to a database and to develop a desktop application.

• SQL Server Data Mining Add-Ins doesn't work with non-English regional settings

  I tried Data Mining Add-Ins for Office 2007 - CTP December 2006. Test settings: Windows XP SP2 english with Italian regional settings, Office 2007 english (RTM), SQL Server 2005 Developer (with SP2 CTP Dec06) and Data Mining Add-ins for Office 2007 (CTP Dec06). If I keep regional settings in Italian, I get error like this: Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD)) If I change regional settings to English, the Add-in works. I found this description as the possible cause of the problem: http://msdn2.microsoft.com/en-us/library/ms178780(vs.80).aspx - if this is the issue, it would be necessary to change the ExcelLocale1033Attribute on the component.

• Visual Studio 2008 (Pre-release) WPF application makes call to server through WCF and hangs

  Hi, OK, this is what we did: Created two console applications, one server, one client. Implemented an server interface and callback. After setting the config files on server and client (using named pipes and WCF) we got everything to work. We are making a call to the server, and within this call, the server calls the client back [ServiceBehavior(InstanceContextMode = InstanceContextMode.Single,ConcurrencyMode=ConcurrencyMode.Reentrant)] Then we switched the client to a WPF (STAThreading). When the WPF app calls the server, the call makes it to the server, but never comes back. The client just times out... The really weird thing is that this only happens if we create the service in the Button handler, code looks like this: [Button handler c ...Show All

• Visual C# Default value for C# properties/functions?

  In VB .NET, I can create a property or function that doesn't explicitly return a value. For example: ReadOnly Property FallThrough() As Integer Get End Get End Property I can leave that property as-is, and it will return 0 when I retrieve its value. I'd like to be able to do the same thing in C#, but it looks like it requires a value to be explicitly returned. The problem is I'm going to have properties with many different data types (so I can't just return 0 in every case) and my requirements say that I can't use the System.Reflection namespace. Basically, I have some code that goes into each property, if certain criteria aren't met, I'd like to just return the initial/default value for whatever data t ...Show All

• Visual FoxPro Memo field conversion

  I am not a Foxpro developer so I'm throwing myself on the kindness of my foxpro brethern. I'm converting data from a foxpro system into Oracle and have run into a problem with a memo field. The data appears to be stored in a .fpt file and I haven't a clue as to how to get to the data and and convert it (including the foreign key) into a text file, excell or any other format that I can use. Any advice you can give me will be greatly appreciated. Alex Feldstein wrote: A FoxPro table is a DBF.

• Visual Studio Printing without the ReportViewer

  In a Win Forms app, is it possible to print a report without using the ReportViewer control I want to provide a print button on a Form (like Outlook does) and then use an embedded Report to print the data so I don't really need the ReportViewer. I would want to display the PrinterDialog though and use the settings from here to control the printed Report. Is this possible too Regards Graham I figured out the print quality issue. The sample code in this post uses the drawimage improperly.
