Grab the handle to the app's main wind ...Show All

• SQL Server remote queries (linked servers) wait or timeout during a DBReindex of any table/index

  SQL2000 SP4 - build 2039 and also tested with a newly applied build 2162 It looks like when a SQLMaint optimization job OR a DBCC DBReindex is executed on ServerA, remote queries (at least using linked servers) to ServerA do not work.  They wait until the DBReindex is complete or until the connection (if connection has a specified timeout) times them out. Why can I not execute a remote query during an index rebuild   The query being run in the remote connection is very simple and does not read a table being 'reindexed'.  IE, I can run the same query locally during the reindex and it works.

• .NET Development Finalizer thread priority (exploit) ?

  Due to a design mistake, I have run into an infinite loop within the finalizer thread. As a consequence the VS interface was almost freezed (I was not able to click on Debug All for example). The Windows Task Manager (running with the "Above Normal" priority) was also almost freezed too. Therefore I have checked the finalizer thread priority, and I have found out that the finalizer thread priority is set to Highest . Since a .Net application can simply get control of the finalizer thread through a disposable object, it looks like it can increase is thread priority beyond the process base priority. Such behavior pretty much look like an "exp ...Show All

• Visual Studio Express Editions Using and saving Properties.Settings.Default.XXX

  I have been using Properties.Settings.Default.XXX to load and save user config settings (scope=user). Now, I want to set scope=application, and store general settings such as database server. I would like the user to be able to create this file, if it is not present using a dialog in my app, but it seems as though the settings are read-only if I set scope to application. If this is the case, what is the best way to store application settings which: (1) need to be stored in a text file in the app folder that is easily readable and editable. (2) Can be read and saved from the app. (3) Can be parsed easily by the app to ensure that all required ...Show All
