• Visual Studio How to avoid failures in "failures.log"?

  Hi! When starting VSS-Administrator (2005), there is permanently a list of users which had produced inconsistencies in the database. Even after running analyze.exe, the same errors occur. What is the cause Thx. It is likely that VSS or VS is crashing for those users, or they are killing the SSExp or VS processes. When VSS is not shutdown gracefully, a temporary file remains in the user's temp folder. Next time VSS is open against the same database, the user is warned there might be corruption in the database and the user's name is written in failures.log. The failures.log file is read when you start ssadmin - the administrator is warned then to run analyze on the database. I was also told there is ...Show All

• SQL Server IUSER Security Risk??

  We have an old ASP application that authenticates to a SQL Server 2000 database using the IUSER account. We are exploring the possibility of moving it to a DMZ so users can access from home. The IUSER account is being used for all database activity for this application. Is there any reason to be concerned about using IUSER as opposed to sql authentication for this tool, or any other security risks I should be wary of. Mind you there may be some sensitive information contained in the database. Thanks in advance. I would recommend either application roles or some other security method, such as a middle-tier or at least SQL Server security to access the database rather than this user. For one thing, you c ...Show All

• Visual Studio Team System Feature Request: Sql Data Compare-limit what is compared by table

  CTP5 is great! As a developer, I am excited about the new MSBuild functionality. This will allow us to update our developer DB after each stage build. However the data compare piece does not appear to have the ability to limit what is compared/updated on a table level (i.e only compare/update Users with age>40). Perhaps a bad example, but when your stage DB is 15GB, it would be great to be able to pull down a sub set of your larger tables to your Dev environment. Typically we only want to pull down data related to specific User Sets (ie. Users in specific companies etc.). Thanks for forwarding my table level filters suggestion. Not caching identical records will help with the amount of space req ...Show All

• Commerce Server Any way to make the CS 2007 help portable?

  This is kind of off topic, but hopefully one of you legends will have a great solution. Is there any easy way to copy the Commerce Server help onto another PC This used to be easy as it was a single CHM file. However, the help system has changed again and this no longer seems possible. I can't just install the Help as the install will not run without pre-reqs. I want to do this do I can do design work on another PC that does not have CS on. I know the docs are online, but it is not a great experience... You can always use the online version of Commerce Server 2007 Documentation ( http://msdn2.microsoft.com/en-us/library/ms864793.aspx ) on computers where you don't want to install the entire product.

• Windows Forms change Color of dataGridView line

  1) How to change Color of dataGridView line 2) How to find a value in dataGridView and make it highlight Thanks Hi Bender I need a similar mechanism, but when I tried your method it did not work. It works when the cell is "visible", but not otherwise. I have a column in my grid that is "invisible" and I need to compare the value in this "cell" to a constant value to see if the row needs to be highlighted or not. For example, I will look at the NT user logged on and if the user appears in the "hidden" column that row would be highlighted. Any help/suggestions would be greatly appreciated.
