• .NET Development Regular expression - date validation in c#

  I am trying to validate a string input of nine characters, such as: 200504031 The first eight character must be a valid date entry, and the nineth (last) character must be between 1-9. Does anyone know how i can implement this Thanks Hi, This would be close "[1-2][0-9][0-9][0-9][0-1][0-9][0-3][0-9][1-9]" but not totally correct as it allow month values above 12 and days above 31 not to speak of months with 28, 29, 30 or 31 days. If you are not totally bound to using a regex, you can use DateTime.TryParse on the first 8 charaters of the string and do a separate check on the 9th character. -- SvenC ...Show All

• Visual Basic Converting VB6 DLL to VBNET

  I have converted a VB6 DDL, used in many Excel and Access applications, and can't use it after conversion. I have compiled using "Register for COM Interop" option and referenced the .TLB file within Access VBA. Access ends when I try to run it. I found that using object browser I can see all the Classes in the DLL. However, I can't see any of the methods of the Classes in the DLL. Can someone help me with it Thanks Thanks for your reply John.

• Game Technologies: DirectX, XNA, XACT, etc. Hi, im new to XNA

  Hey, I just recently found out about Microsoft's XNA program. I have some questions and was hoping someone could answer me. 1. I have a game that I am currently developing on Windows XP, it runs off DX9. Is there any possible way I could port it from the PC to XNA so I could play it on the 360 2. Will it cost money, and if so (which im asuming) how much 3. Will I need a special dev 360 or will I be able to use my off-the-shelf 360 4. If I have to completely re-create my game for XNA since I couldnt port it, Will there be engines I could use or will I be forced to create my own engine, and if so what language can I use 5. Where/when can I download this and start using it 6. What CDs/DVDs do I have to buy to work on the 360 ...Show All

• 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 BTW, the DBCC PAGE command is an undocumented command which means it is not supported by Microsoft (but nobody is stopping you from not using them). Try Googling around for some references on these undocumented commands, stored procedures and functions and you will find a lot of useful ones. ...Show All

As I display these records, I want to compare the date in that field to the current date and if it is less than today, I want to alter a seperate label to indicate that the item on the record is expired.

• Software Development for Windows Vista Missinng flash.ocx in vista rc1.....

  Hello i need help about windows vista rc1 build 5600 ... I tried to install my router's software but the autorun could not run because flash.ocx was missing (installing flash player 8 did not solve the problem) In windows xp/2000 the autorun works properly. What should i do plz help me Hello. The autorun program requires Adobe Flash ActiveX component which is not available in Windows Vista by default. You have probably tried to install Flash Player from other browser than MSIE. Since Adobe doesn't provide direct links to the component's installer, a browser specific version is always downloaded. First of all, try installing the player from this site: http://www.softwarepatch.com/internet/flash.html If this ...Show All

  The subject method appears in sample code for WindowsIdentity.  I cannot find information about the method WindowsIdentityMembers.LogonUser() in Help (i.e. MSDN for Whidby).  The method is a real aid to developers who previously were required to do a P/Invoke to unmanaged code to obtain the token.  See code from sample... // Retrieve the Windows account token for the current user.

• SQL Server SharePoint and Reporting Services on 1 box

  I have seen and understand the articles about how to configure one IIS to host both SharePoint and Reporting Services. Isn't it better to have a different machine host the Reporting Services - or am I misunderstanding how RS works. Maybe all the number crunching and data manipulation is handled through the data source connection on that server and RS just displays it on the web That would argue that having them both on the same server isn't too much. But in any case - if I did want them on seperate servers - can I do that Server1 has SharePoint referancing Webpart Reports that reside on Server2 Yes, you can have SharePoint and RS on different boxes. Just make sure to type in the correct URL when using th ...Show All

• SQL Server SQL Server Express and AMD 64 bit dual cores

  Hello All, I've installed SQL Server Express and its Management Studio Express on two different machines with the same hardware. http://msdn.microsoft.com/vstudio/express/sql/download/ Both machines are suffering the same problem. At least once a day, when the user starts a process, it will peg the cpu at 50% (so presumably one core is at 100%) and explorer.exe will hang. If you start another process, it will hang in the same way. Killing explorer and restarting it does not seem to solve the problem. Rebooting seems like the only course of action. I think this is related to SQL Server Express because this did not happen on either machine until it was installed on the machines, and it started happening immediately after installi ...Show All
