• SQL Server Merge Join vs. Lookup vs. Custom Script - which is fastest?

  Very often we have 50'000+ rows which you need to pull values from different source (e.g. CityNames from citycode in Excel file). Currently we are using Lookup - but the questions is which of those 3 options is best in performance wise Crispin wrote: Do a fair comparison though. Either change your query to cache the rows from SQL or disable caching on the lookup. Oranges != Apples. A non cached lookup will be expremely slow as was your script component. It would be best to try to replicate full caching in the script component. The purpose of the exercise was to see which was faster. So, we know how fast (and legitimately so) the lookup component was, now how fast can we get the script component to process The ...Show All

• Visual C# Raising events from one thread to other

  Hello, I am new in C# and would appreciate any information on standard ways to raise events from worker thread (System.Threading.Thread) to the main UI thread, where the main form is created and lives. Here I interested in the events only (as they usually used within the thread scope), not Control.Invoke()/BeginInvoke(), not BackgroundWorker class, as they are more or less learnt and OK. By default, raised events go to the same thread, is it the only behavior If not, how I should redirect them into UI thread's message loop Thank you in advance. Try this thread. I had the same question and it was answered well in this thread. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=797 ...Show All

• Visual Studio Team System Installing TFS with the default web site on a port other than 80

  Hi, I'm working on an install of TFS on a an exisiting server where we've moved the default web site (along with Reporting Services and SharePoint) away from port 80. Is there an easy way to get the TFS install to work in this situation, or would it be simpler to move these sites back to port 80 for the install then reconfigure everything afterwards I've found some references on the internet to doing the latter, although these were mostly on the personal weblogs of sysadmins - so far I've not found any "official" documentation or guidance on doing any of this. Any pointers or advice gratefully received. I'll be experiementing in the meantime so if I come up with a working solution I'll post it in this thread. Thanks, ...Show All

• Visual C++ LNK4098 and static libraries using different runtime types

  I've inherited a project that has various problems. This project is a DLL linking with the MT run-time libraries. It also links to several static libraries that are outside of my control but I believe they're all compiled with the same version of Visual C++. I'm assuming the LNK4098 warning is being dumped out because one or more of the other static libs were compiled with a different runtime type (assuming single threaded). The dox for LNK4098 mention "...prevent mixing different [run-time] types... You receive this warning if you try to use different types ... of the run-time library...". A warning doesn't seem like prevention to me. It then goes on to describe the NODEFAULTLIB option and what run-time libraries to ignore wh ...Show All

• Windows Forms Horizontal scrolling with SHIFT and MouseWheel

  I would like to change the behavior of ScrollableControl that it is able to scroll horizontal with SHIFT and MouseWheel. This behavior is seen in some applications like the Visual Studio Class Designer. My idea was: protected override void OnMouseWheel( MouseEventArgs e) { if (ModifierKeys == Keys .Shift) { // Scroll horizontal ... } else { // Scroll vertical ... } // Don't call the base method because it would call the default implementation of ScrollableControl // base.OnMouseWheel(e); // Fire the event to all listeners if (MouseWheel != null ) { MouseWheel(e); } } The problem is that I am not able to fire the Event MouseWheel. Only the base class Control is able to fire this event. Ha ...Show All

• SQL Server Is it possible to version custom SSIS components?

  Is it possible to use versioning at all with SSIS components My experience so far is that I have not figured out how version them at all, because if I change the version number, then apparently the <property name="UserComponentTypeName" ...> has to be changed in every single reference to the component, in every dataflow, in every single dtsx file that uses the component at all -- this will be a tremendous headache as some of this stuff is in source control. It seemsl clearly infeasible to check out and substitute and change all these references, and check them all back in, except very infrequently -- surely not feasible to do it for each small change. I am in the habit of versioning dlls and assemblies, and actually chang ...Show All
