• Visual Studio 2008 (Pre-release) query and cache

  So under what kind of query is the cache used instead of actually making another query Is it only for exact match (i.e. "==") queries Could you expand or ref an article. The cache is checked when the query is a simple table.Where(pred) or table.First(pred) where the predicate refers only to the primary key. Otherwise the query is always sent and the cache only checked after the results are retrieved. ...Show All

• Smart Device Development Upgrade path for CF 1.1 design time capable custom controls to CF 2.0

  Does anybody know of one I read in this post: http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=129715&SiteID=1 of the genasm.exe tool, but searching on http://msdn.microsoft.com/ for it produces no results at all. There also does not seem to be an automatic way of creating the necessary *.xmta file outside of VS2005. Can anybody give me a heads up on this one please It does seem a bit ridiculous that none of the work I put in to create my CF 1.1 design time capable custom control can be used in developing a CF 2.0 version of it. You're right. There's no automatic way to do that. > It does seem a bit ridiculous that none ...Show All

• SQL Server Re : Enabling / Disabling Data Flow Tasks

  Hello, I have created around 10 seperate packages for our application data load. Now I am planning to create a master package (or a wrapper package) which will execute all the 10 packages (thru execute package task). Then I have a job which executes the master package at a given date and time. Question : How can I enable / disable execution of each package within the master package depending upon a flag variable. The reason why I need this mechanism is if the flag = 0 then I don't want all 10 packages within master package to execute and if flag = 1 then master package execution should begin and subsequently execute all packages wi ...Show All

• Windows Forms Is there a built in Most Recently Used (MRU) class?

  I want to implement a MRU list for recent files in my Windows Forms application, and I want the data to be stored in the user.settings file. This seems like a very common task, so I'm wondering if there is something like this built into the framework. Or available somewhere else. Any thoughts Thanks!

• Windows Forms CallBack in GridView

  Hello: I am in the process of extending GridView and adding some functionalities. For example, I added a single row click to postback and handle the event. I would like now to be able to do a CallBack instead of PostBack. Do you know if there is a whitepaper on how that CallBack functionality is added to the Grid currently through sorting and paging I believe it is better to follow the same technique used. I have been trying for some time, im getting all the needed methods and functions, and I have added for example: Grid1.EditIndex = e.GridViewRow.RowIndex; inside the handler of the sinlge click which is being fired upon a ...Show All

• Visual Basic Regions bug

  Every day after I’ve been working in the IDE for a while, the collapsed #regions will not open with a single click on the plus sign anymore. Instead it takes 5 to 10 clicks to open them. Actually in different source code files it takes a different number of clicks in order to un-collapse a #region . (but always the same number of clicks within the same source code file) I sure hope this will be fixed soon. It's been doing this all along since I switched in February. Any idea what's causing this Which versions on VB are you using.... VS Studio, VB Express Has it been doing this f ...Show All
