• SQL Server Help!!!! Restore file mdf after exec "Drop table..." to previous state.

  Hi all. First, sorry about my poor english. I have a database which above 6 gb data and i have droped all table in my database. I try to restore from log file but my database is set to simple backup and auto shrink so log file doesn't help anymore. I have used some software to recovery from log file too but useless. My only hope right now is mdf file. Please help me. How could i restore my mdf file to state before i droped tables. Thanks Copy it from the results window and paste it into Notepad, another Query window etc. This is a 100% manual process. There are zero tools. There are no shortcuts. There is no easy way to do this. In essence you are going to manually type back in every single piece of data within the database. If you ...Show All

• .NET Development Issue with DateTime class

  I've got a program which uses DateTime to get the year, date (ie, 12 or 13) and the month to put into a string. This is the code: DateTime now = new DateTime(); now = DateTime.UtcNow; string year = now.Year.ToString(); string month = now.ToLongDateString(); month = month.Substring(3); month = month.Substring(0, month.Length - 5); string day = now.Day.ToString(); string datetoday = year + " " + month + " " + day; Although it works well on my system (and on those of many others), some users of the program have reported that the string "datetoday" appears as " 2006 rsday, 28 December 28". These users have been running .NET 3.0 an ...Show All

• Visual Studio Express Editions changing current directory to bin

  Hello all, I'm currently working on a project that requires me to switch the current directory of the project to the project's bin. I've looked in several places, and can't figure out how to do it. Does anyone have any ideas Thanks so much for any input... sorry for this stupid question -Robert Oh, no, sorry for being unclear... basically my predicament is that I've got an openfile dialog box that... when a user opens a file in a different directory, the path that the program saves files to (or whatnot) changes from the bin to the directory that was selected by the user via the openfiledialog. I'm wondering how I change it back to the bin after it gets changed from the openfiledialog. Again, sorry for being unclear, and thanks a tr ...Show All

• .NET Development Strange event behaviour

  Hello, i've got Windows Forms app, with own class instance with SerialPort inside. Everything working fine until i'm firing event from own class instance and handling it in form1. When i debug i see event handler incoming, correct args too, but when i try to show the args data in label or MessageBox nothing happen. I think it's some kind of 'thread' problem, because SerialPort runs in separate thread on background, i think. Could you be so kind and help me, please are you able to post this code remember, if you are trying to show the args/data recieved in a label, you need to invoke the UI for it to display the data on its thread, otherwise you will (99% of the time) recieve an illegal cross-t ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Numeric performance on 360

  A question for the framework/VM guys... I have ported one of my simpler benchmarks to the 360, and find that the numeric performance is running 5x slower than my 2.8GHz P4 desktop. Now I was expecting a drop in performance on the 360, allowing for the difference in CPU implementation (in order execution / branch prediction etc), but nothing like this magnitude! The benchmark simply transforms a source array of Vector4s to a destination array of Vector4s, using a 4x4 matrix. Have you guys done any benchmarking of pure numeric perf, and if so is this in line with what you get Andy. Okay, some hard numbers from my game. Basically, I'm decoding some data, creating meshes from some previously-loade ...Show All

• Windows Forms ContextMenuStrip behavior on a TreeView (repost)

  Reposting after getting Technet subscription set up: In VS2005 (SP1) I want to use a ContextMenuStrip as a context menu on a treeview, and found that doing a contextMenuStrip.Show() doesn't block while in the Show method like contextMenu.Show() does for the older style ContextMenu object. This causes a problem if the user right-clicks a node other than what is currently selected. With the contextMenu.Show(), the right-clicked node shows highlighted while the menu is visible and then again highlights the truly selected node again once a menu item is chosen or the user Escapes. With the contextMenuStrip.Show(), only the truly selected node is highlighted while the context menu is visible, which can confuse the user. Was this change by ...Show All

• SQL Server Messagebox in T-SQL

  Hi All, I am struggling to display a simple messagebox in a trigger in SQL 2005. I have created a script in which I would like to have a popup dialogue warning the user of something. The only thing I could find that comes close to what i want to do is the RAISEERROR statment. If i use this however with a serverity level of more that 10, it will roll back the data and the entire trigger is made useless. If I use a severity level of 10 or less, the message does not display but the transaction is not rolled back. I have also tried the PRINT statement but this does not popup with a dialogue either. Any ideas as I am stuck. Cheers, Todd There is no way to display messages that will wait for user re ...Show All
