• Visual Studio Team System % Time in RT checks threshold

  Hi (slumley :)), I am loadtesting a sample ASP.NET web site with 4 requests. All of them extract image blob from the DB, through asp.net handler, and show it along with simple additional data. I get critical threshold value of 25% for the '% Time in RT checks' counter. How can I further investigate where the problem is located Thanks, Martin Sometimes the threshold rule on % Time in RT checks will be fired when there really isn't a problem, so before you spend a lot of time trying to figure this out, you should also look at the value for the performance counter "Total Runtime Checks" in the same category (both are ...Show All

• Windows Forms Looking for a quick and smart way to recreate a project.

  Hi, I think I have some problem with a project of mine.  It was probably converted from the older VS.Net to VS.Net2003.  I am having those corrupted metafile database link error.  I was told that I should start from a clean VS.Net2003 project and import the old files back.  The problem is that the files for Windows Forms look different in the solution explorer than before.  In the old project, I can see the form icon next to the header file and a resource file show as a child under it.  Now these related Windows Forms files seem to be unrelated in the Solution Explorer and I can no longer double-click on the h ...Show All

• Visual Studio constrain the number of a specific shape

  hi, i have three different shapes that i could 'drag&drop' from the toolbox: shapeA, shapeB, shapeC how can i constrain if there is already a shapeA within my designer workspace, that a second shapeA cannot be drag&dropped to the designer workspace The constraint should be, that only one shapeA within the designer workspace is allowed. Any ideas Thanks! Hi, I think your best option is to wait for the upcomming CTP that has a new "validation framework" included. It should take to long for this CTP to arrive. The validation framework makes it possible write constraints for a concept in pure C#. I ...Show All

But I want to access this service repeatedly, and drive the thing from a table. I've got the Foreach Loop correctly getting variables from the recordset I populate from the table. That works and I can run a script with msgbox showing all the correct values being read from the table. My problem is taking these variables and sticking them in the Name / Type / Value entries in the Input tab of the Web Service Task. There doesn't seem to be any mechanism for dynamically updating these at runtime, and if there isn't, that ...Show All
