I basically want the user to be able to enter an equation like SQRT(5 * 6) / (2 ^ 4) and then I want vb to use system.math to solve it. If I write this in my code, vb is able to do it, so how could I do this at runtime.

View 10 RepliesBuild A Date Calculator Utility (DateCalc)?
May 10, 2011I am trying to build a date calculator utility (DateCalc). It returns the number of days,weeks, months etc between two dates.I worked hard and long trying to find out how to convert a date into a format on which you can perform math operations (for the "what's the date in 'n' days time" part) and it works! I can also use the minus operator to find out previous dates, from say 10000 days ago... BUT...I want to develop it further, and this is where I need help (i am still very newbie remember)Can you help me to find a way to code this bit to ignore weekends and saturdays or sundays individually, and a range of dates in its calculation? I have two datetime pickers and a some checkboxes.DTPickFromDTPickToChkBoxExWeekendChkBoxEXSaturdaysChkBoxExSundays An image of my form and it's components is here :--> [URL] Also, as part of my 'Datecalc', I'd like to find the dates of every other saturday and sunday in the future.

View 2 RepliesVS 2008 Make A Release Build Instead Of A Debug Build?
May 3, 2010I am using 2008 Express Edition. I am trying to make a Release build instead of a Debug build.Under Tools->Options, Projects and Solutions->General - I checked Show advanced build configurations. The option to switch configurations does not show up in the IDE.
After this, I went to the Project Properties->Compile and switched the Configuration from Active(Debug) to Release.After building, I looked in my project directory, however only in the Debug sub-directory was the .exe and nothing in the Release sub-directory.I have used Visual C++ Express Edition, where I noticed that if you do not change to Release in the IDE than after changing to Release in properties, resets the project to the last configuration setting which is usually Debug.how to make the Debug/Release box available in the IDE, since Tools/Options does not make it show up?

View 12 RepliesPerform Release Build And Not Debug Build For Exe
Aug 4, 2010I have some very simple questions about making a release build exe in vb.net using MS VB 2010 Express.
I realize that my project's executable is built in the bin/debug folder. However, when I copy this to any other location on my computer or someone else's, this executable does not function. I have read that I need to create a release build but in MS VB 2010 Express, when I use the Project-Properties menu and change the Compile tab configuration to Release and the path to binRelease, I still get the exe in the binDebug folder and not the binRelease folder.
1) Is it normal that exe's from the debug folder do not function outside of the debug folder?
2) Most importantly, if the release build produces a faster exe, could someone please explain step by step how to do this with MS VB 2010 Express ? I do not see any button on the compile tab in the project properties that actually builds the release.

VB Console App Calculator?
Oct 26, 2011I need a little help in programming a console calculator.I'll start by saying that VB is a new programming language for me. I started a class in school that uses VB to teach an introduction to computer logic and programming. It's not the first language i have learned, but it the first one that i have gotten in depth with in console apps.I have a basic set up of asking the user for the first number, then the operator, then the second number.I'm currently using a Select Case statement to start the calculation area of the program, a Do Until at the beginning of the Select Case for a repeat, then it proceeds to getting the numbers and operators.
I'm also wanting to get all the possible math operators that VB provides included.What i'm hoping for is to clean up my code and make it to where the program asks the user for the equation itself. Example.
Console.WriteLine("Enter the equation")
equation = Console.ReadKey()
