• How to prevent form from being activated when the users clicks on it?

  - by riot_starter

  I have a main form and non-modal autocomplete form. How can I prevent the autocomplete form from being activated by the user, when the user clicks on the list in the autocomplete form? So, basically I want the autocomplete form the receive the mouse click message when the users clicks, but to never become active, because it causes problems with a third-party component in the main form over which I have no control.

• Is there a way to easily serialize form input into xml or yaml for database storage?

  - by aaandre

  I am dealing with an old app in asp classic vbscript. I'd like to store the input of a form in a database text field as the form fields are a subject to frequent change and I don't feel like normalizing the old database. Any solutions for serialization in vbscript? Thank you!

• MVC Entity Framework: Cannot open user default database. Login failed.

  - by Michael

  This type of stuff drives me nuts. I'm having trouble finding the exact issue that I'm having, maybe I just don't know the terminology. Anyway, I had a working website using MVC and Entity Framework, but then I coded an error in a partial view page (ascx). Then all of a sudden I started to get this message. Cannot open user default database. Login failed. Login failed for user 'NT AUTHORITY\SYSTEM' I've found plenty of suggestions about opening SQL Server Management Studio, Double Click on Security, Double Click on Logins, Double click on NT AUTHORITY\SYSTEM and then double click on User Mapping. In this view I'm suppose to check the box for my database so that this user is mapped to this login. However, since I created my database in Visio Studio 2008 as part of my solution, it doesn't show up to allow me to click on it. So what do I do now? What drives me nuts is that everything was working fine. I was using my computer name to access the website and everything was working fine until the coding error. I've fix the error but still getting the error. I should also mention that this error started yesterday too around the same time but later cleared itself up. If I use localhost to access the site, it works just fine. IIS7 configuration for my website: Application Pool = DefaultAppPool Physical Path Credentials Logon = ClearText With in connection strings. I do see the one for my database in this solution. Entry Type is local metadata=res://*/Models.DataModel.csdl|res://*/Models.DataModel.ssdl|res://*/Models.DataModel.msl; provider=System.Data.SqlClient; provider connection string="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\FFBall.mdf;Integrated Security=True;User Instance=True;MultipleActiveResultSets=True" And somewhere I remember changing the identity from Network Service to LocalSystem. Because when I first stared I was getting this same message, but I changed this value and it started working. I saw that suggested somewhere too but I do not recall. Wait I remember now, I believe in IIS7, under Application Pools, DefaultAppPool identity is set to LocalSystem. Additional things I've tried. Restart the computer Recycle the application pool. Antivirus isn't running. Any help would be appreciated. Thank you in advance.

• How do I quickly rename a mysql database (change schema name)?

  - by deadprogrammer

  Usually I just dump the database and reimport it with a new name. This is not an option for very big databases. Apparently RENAME {DATABASE | SCHEMA} db_name TO new_db_name; does bad things, exist only in a handful of versions, and is a bad idea overall. Oh, one more thing - this needs to work with InnoDB, which stores things very differently than MyISAM.

• How can I split mySQL query logs by database?

  - by barnaby

  I've been trying to implement a mySQL Proxy solution that can separate out the queries into per-database logs. Everything I've Googled has pointed to mySQL Proxy but I can only seem to capture the database a connection was opened to, not which the current query is being issued against. Is it even possible? Is there a different tool to use? Thanks for any suggestions.

• Faster way to know the total number of rows in MySQL database?

  - by Starx

  If I need to know the total number of rows in a table of database I do something like this: $query = "SELECT * FROM tablename WHERE link='1';"; $result = mysql_query($query); $rows = mysql_fetch_array($result); $count = count($rows); So you see the total number of data is recovered scanning through the entire database. Is there a better way?
