Re: Encryption/Decryption of files instantly zorro.tmh1-Apr-06 23:00 zorro.tmh 1-Apr-06 23:00  Dear Michel, How can open the retuned MemoryStream Object ? in my case this object is a video file and I want to play it in media player .. the media player needs a path .. how can I get the path ? Thanks in advance . Re: Encryption/Decryption of files instantly Le centriste3-Apr-06 4:00 Le centriste 3-Apr-06 4:00  The MemorySTream object resides in memory, unlike a FileStream, which is on disk. If the player needs a path, you are screwed, because you will need to have the decrypted data on disk. Read the player's documentation to see if there is a possibilty of streaming to it. -------- "I say no to drugs, but they don't listen." - Marilyn Manson Creating ODBC DSN Entries using .

Why Sleep()?? _Dito_30-Mar-06 0:16 _Dito_ 30-Mar-06 0:16  I have a really strange problem in my ASP.NET app. the situation is really usual Do some changes to DB and then refresh data for client --- SqlCommand myCmd = new SqlCommand ('UPDATE TBL SET ....'); MyTypedDataTable tbl = MyTypedTableAdapter.GetData(); -- so everybody have done something like this. update and refresh. BUT! Last GetData() returns table without any update. If I will add Thread.Sleep() between this to lines of code, then everything is working fine. Do anybody has any ideas why this happens? all these components are default without any "starnge" settings. there is no cashing and no async calls. just normal SqlCommand and SqlTableAdapter. Re: ExecuteNonQuery? Why Sleep()?? Antony M Kancidrowski30-Mar-06 1:20 Antony M Kancidrowski 30-Mar-06 1:20  Why don't you make changes to the data in the TableAdapter then use TableAdapter.Update to send the changes back to the database?

Goto: Program Files->Microsoft Visual Studio 2005->Visual Studio Remote Tools->Remote File Viewer It will ask what you want to connect to, choose the Emulator. You can copy files back and forth in the same way you use Explorer. Ant. I'm hard, yet soft. I'm coloured, yet clear. I'm fruity and sweet. I'm jelly, what am I?

I have a problem with inheritance in .NET: I think the Queen can inherit both Rock, Elephant because the queen move like the rock + elephant. But .NET does not support multi inheritace.

Antony M Kancidrowski30-Mar-06 0:39 Antony M Kancidrowski 30-Mar-06 0:39  The interfaces would declare the functions. You would implement the functions in the class that derives from the interface.

It appears that the epoch for System.DateTime within .NET 2.0 is 30/12/1899 where as the epoch for smalldatetime within MSDE (v8 stuffs) is 1/1/1900. Therefore when using the ToOADate() method the value returned is 2 days out (i.e. 2.0 greater than the value I ought to be passing to the database) I know I can adjust the value so that the difference is taken into account but I was wondering whether this is a mistake introduced in .NET 2.0 or is a known difference that we need to accommodate for.

Each user must be allowed to change his password at any time (so the passwords (or better: the password md5 hashes) cannot be "hard coded" in the software); therefore I'm looking for the best way to store the passwords, and I would like to avoid using the windows registry. Of course I cannot simply write the user/md5hash pairs in a regular text file, otherwise anyone could simply replace the md5 hashes with the hashes of known passwords and get full access to the system. Can anybody help me? Thank you. Re: Application password storage Antony M Kancidrowski29-Mar-06 23:14 Antony M Kancidrowski 29-Mar-06 23:14  It is probably best practice to encrypt the storage data file and therefore not possible for someone to tamper with the contents.

Sometimes on error word doesn't close correctly and stays unmotivated and blocking in memory. This apps can not continue until word is cleaned from memory. I have no ideas where and how I can get these proc-ID's. But in an very useful app called "Process Explorer" you can see the relationship between the apps who called sub-apps (master - slave). Who can show me a codesnippet, which returns the proc ID's of apps which were started from my (master) application. With this information I could kill the lazy blocking (word)-exe's. Thanks for all your good ideas in advance. Frank -- modified at 5:00 Thursday 30th March, 2006
