• Windows Forms Closing forms in Control validation events...

  I am developing an application with custom security mechanism. Whenever a TextBox on one of my application's form loses focus, I need to validate it. Depending on its contents, I sometimes have to close the form. The validation occurs in the security mechanism implemented, which closes the form using the My.Application.OpenForms collection, if need be. It took me a complete day to figure out that a form cannot be closed if one of its controls Validating or Validated events are being processed (the Form.Close() instruction simply doesn't do anything as if it were not there). Can someone tell me why it is so, & how can I overcome it The amount of code in the framework dedicated to making Validating wo ...Show All

• SQL Server Where to use SQLCLR ? Data access is not recommended?

  Just wondering which scenarios is suitable to use SQLCLR. Any kind of data access is not recommended I guess. Only things that cannot be easily done in TSQL should be done in SQLCLR but why Can't those things be done in app layer itself Scenarios recommended for SQL CLR: - External data access like filesystem, registry etc - Complex calculation - Recursion without data access (this can be implemented with CTE for data access) If data access with SQL CLR is not recommended why should CLR should be even used and logic reside in database layer.. it makes no sense to me. Any thoughts Hello Sequel2k5, I suppose set-based TSQL would be faster than iterating over a result set, but again, I could just issue a set ...Show All

• SQL Server Data script task - how to generate multiple rows from one row ? (string splitter)

  Hi in input we have a set of rows, each one with a column containing a string (eg: "AAOOOOAAAOOA"). We'd like to split this string (using a vb.net data script task) into tokens (eg: "AA", then "OOOO","AAA","OO","A"), and to output one line per token. How can we achieve that with a vb.net data script task (Or anything else ) best regards Thibaut DarrenSQLIS wrote: Phil, I agree in principal, the native stock components should be faster as a rule, but have you got any references Yep, no problem... http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=857796&SiteID=1 ...Show All

• .NET Development WebClient.DownloadFile - random 500 byte download problem - pls help

  I have been suffering from a random problem that I cannot pin down.  Quite simply I am trying to download a file using a very simple application.  The problem is that sometimes the full file is downloaded and other times only the first 500bytes.  This occurs with different files of different types. I have used an HTTP sniffer program and the full file is included in the http response! The file is using a "web folders" uri and therefore uses FileWebRequest/Response and not HttpWebRequest/Response. The original code is: webClient.DownloadFile(filePath, "C:\somefile.doc") This was revised to the following so I could get a byte count: Dim request As FileWebRequest = FileWebRequest.CreateDefault(New Uri(filePath)) ...Show All

You can serialize the XML back to file (DB) with XmlWriter. ...Show All

• SQL Server Adding a 2nd subscrber makes my Merge replication blow up.

  I have two machines running SQL Express that I am attempting to use as proxies for a client application as the security admin has deemed that outside clients can not connect directly to the main DB servers. When I have one of the SQL Express boxes subscribed to my SQL 2005 standard server, everything is happy, but when I attempt to add the second SQL Express box as a subscriber, everything seems to blow up. OK, I'm setup as a merge with updates and no filter since I want all of the servers to get all of the data. I'm also on a non-standard port but have my aliases setup, and I don't have any connection issues. When I run the subscription wizard from the management studio, it comes back with "Success", but about 2 seconds la ...Show All

• Audio and Video Development full file encyption

  What's the design consideration of Media Foundation in the case of full file encyption, where the media source cannot get stream description or split stream without the decryptor (to decrypt at least part of a file) The assumption in Media Foundation is that the Media Source should be able to describe the presentation, and this description should be accessible even to non-protection-savvy code. (Note that as a corollary, Media Sources that have muxed streams are expected to demux them, and in particular that might mean doing a little demuxing even before Start() if doing so is going to be necessary to describe the streams -- i.e. mediatypes, etc) Tell me a little more about what you're doing... format, protection system, e ...Show All
