• Visual C# Random Division

  Hello. I am currently generating 2 random int numbers that will be used to divide between each other (num1 / num2). However, I only want numbers that (when divided), result in an integer number that does not contain a decimal (or remainder). For example: Good numbers: 6/3=2, 10/2=5, etc, Bad numbers: 7/3=2.33, 8/6=1.33, etc. All help is appreciated. Thanks, that should not be that hard. just check if number1%number2 is more than zero. If it is you will get a decimal number like 1.5456, if not you will get an int. Look here for the %-operator: http://cplus.about.com/od/learnin2/l/aa082504e.ht ...Show All

• Visual C++ Redistribution of C runtime libraries without MSI installation

  Hi guys, I'm trying to get an installer of our product working.  I've finally gotten it compiling and running under VS2005.  For various technical and political reasons, I have to use NSIS as our installation technique. This is where the problem begins.  I can't quite see how to redistribute the relevant CRT libraries.  I've been round and round in circles following the MSDN information, and various blog postings (e.g. http://blogs.msdn.com/martynl/archive/2005/10/13/480880.aspx ) but I've not been able to see how I can redistribute the CRT in this way. Obviously, merge modules aren't an option for me.  I've tried pl ...Show All

• Visual Studio Team System Activity: Cost a Development Task

  MSF Agile prescribes that the dev has to cost the task which of course is logical. My question is: in which field of the WIT Task should the dev enter hers/his estimate and what is the prescribed procedure/algorithm . The wit Task has several fields that have to do with estimates and/or amount of work: baseline work, remaining work, work completed, but none of them maps to MS Projects “work” or “duration” fields. (Actually, only the MS Project’s “work” field would be the correct choice for setting the estimate, since the “duration” filed takes the calendar into account.) The wit Scenario has Rough Order of Magnitude field but ...Show All

I have created ASP applications using C# and VB and also windows app using both however, this for this application they want it to "look" like a web based application (imagemaps, gridviews, etc) but it is going to be tied to a single computer because it will be accessing USB ports and various peripherals.
