• SQL Server Copying database using "Copy Database" - still failing after SP2

  I am struggling with the "Copy Database Wizard" in SQL Server 2005. I am used to working with DTS to copy data from one server to another, but with the new tools, I am having serious problems (in fact, it's unusable) 1. When copying a database using the "SQL Management Object" method, I always get errors concerning logins. If I select not to copy logins, I get errors "sp_grantdbaccess failed". If I do select to copy logins, the logins can't be created because the machine names are different (one the source machine, the login is called MACHINE1/mylogin, but on the destination machine, such a login cannot be created) 2. For small databases, I ALWAYS get the error "CREATE DATABASE failed. Primary file must be at least 3 MB to accommodat ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. GraphicsStream.InternalDataPointer null?

  Good day, We are creating a texture from a bitmap region using an unsafe section in C#, but occasionally the InternalDataPointer for the GraphicsStream's returned from Texture.LockRectangle will be null. Following are the relevant lines: Texture texture = new Texture (device, bitmap.Width, bitmap.Height, 1, Usage .Dynamic, Format .A8R8G8B8, Pool .Default); int pitch; GraphicsStream graphicsStream = texture.LockRectangle(0, LockFlags .None, out pitch); unsafe { byte * to = ( byte *)graphicsStream.InternalDataPointer; ... It is a multi-threaded app, but to our knowledge no other thread acts on these members. What could cause a null InternalDataPointer Thanks in advance... ...Show All

• SQL Server sql server lockup after strange error in log, help please.

  Can anyone help me solve why my server is locking up. We're running sql server 2005 ent on a 2 cpu dual core server. With 3gig. Once each the last couple weeks, the machine has hung and the only thing I can find that's suspicious is on the sql server log.  It's below.  After the excerpt is about 50 more different memory errors.  As far as I know there's no ssl configured for log in, it mostly uses private lan cards for security between it and the web/application server. 05/31/2006 14:39:48,spid2s,Unknown,MEMORYCLERK_SQLQUERYEXEC (Total) <nl/> VM Reserved = 0 KB <nl/> VM Committed = 0 KB <nl/> AWE Allocated = 0 KB <nl/> SM Reserved = 0 KB <nl/> SM Committe ...Show All

• Windows Forms Console Output from a Windows Form

  I have a windows form program which also includes a command line interface to a few of its features. When command line options are pased to the program the GUI is not displayed, and the command line code is properly excuted. However none of the output to the console appears. I was able to get the console output to be displayed by having Visual Studio 2005 compile my program as a console app instead of a windows app, but this causes a console window to be opened when you run just the GUI portion of the program. Is there anyway I can get the console output to appear without having this console window opened with my program when running the GUI part may be not related directly to your question but look at ...Show All
