VB calculator code This article is mainly for the beginners. I am trying to explain the use of Control Arrays with the help of Calculator Sample.I feel control arrays are overlooked in classic visual basic.
A Calculator Project in VB NET. In the next few pages, you're going to create a Calculator. We'll make a start on the VB NET code for the all those buttons. Jan 12, 2014. 2010 visual basic code simple calculator simple. How to Create a Simple Calculator in. In VB.Net - VB.NET Tutorials vb calculator code sample.
If the way to implement is understood, it is much useful in reducing the code. Control Arrays can be used in the situations like whenever the need of same controls being used several times in an application. We can make them as an array, and the controls can be accessed by their index in all the respective events VB 6 Control Arrays in form As shown in the following figure, Design the form. Create a Command Button named as Command1 and copy that and paste it 11 times.
This will create a control array. Then assign the text as shown in the figure. All the controls under red boxes are under one group. So design it accordingly. Like wise create cmdOperator control array for the green box group. Now you can use the sample code to try VB Calculator we actually storing the Last Operator used and The first part of the number used in a class level variable.
So that they can be accessed across the events and functions. Since the operators also created as control arrays.
We had drastically reduced the amount of code required for a simple calculator. Source Code - Simple(VB 6.0).
GUEST hi thanks 9/16/2009 7:28:10 AM. GUEST wow nice tnx i can use this 1:00:37 AM. GUEST i really need to know how to use or make a code for my project.we're planning to do some program which is cybercafe program but we really dont know how to use coding.we're done with our interface.the problem is the coding. 7:23:44 AM. GUEST.tnx a lot!! 1/24/2010 7:12:37 PM. GUEST Thanks a lot 2/15/2010 11:22:27 PM.
GUEST thnx buddies 3/22/2010 10:46:15 AM. GUEST really helpful, but i do not get the cmdCleat button too work 4/21/2010 1:51:07 AM. pons It actually clears all the operators and the results. So that it will reset the calculator.
Hope that helps you to understand. If not please elaborate more on where exactly you are unable to understand.
Thanks 4/21/2010 2:13:49 AM. GUEST Thank u soo much.I really need it. 6/3/2010 7:23:32 AM.

Calculator Code In Vb
GUEST code of simple calculator in vb 9/29/2010 9:27:18 PM. GUEST I need some help coding a simple calculator without the number buttons. It is setup with a text box (as display) and 6 buttons ( +, -,., /)(C and CE) Can someone help me get started out atleast.? 10/2/2010 3:29:25 PM.
pons If you dont have number buttons and text box is only for display, how will you get the numbers to work on? Do you recieve it from externaly(from otherforms?) 10/3/2010 2:12:26 AM. GUEST thnx.jejejeje 10/7/2010 7:51:35 AM. GUEST tnx!!
^^ 8:28:15 PM. GUEST thanks you're indeed helpful.^^ gamsahamnida 7:55:02 PM. GUEST Thank u very much am use this code its working very nice 2:47:05 AM. GUEST thank u very much am use this code its working very nice -k.deepa 2:47:48 AM. GUEST THKS 2:57:51 AM. GUEST how do you add an operation that solves the exponent?
Create Calculator In Vb
The symbol looks like this ' ^ '. 2/17/2011 4:55:35 PM. pons I dont have 'Classic Visual Basic' installed in my machine. I checked in.Net and the excel macro(close to vb i guess) i can conclude that MsgBox(8 ^ 3) produces 512. So hope that helps.
If not please explain your questions in detail. Thanks 2/17/2011 6:13:15 PM. GUEST thanks a lot. 2/24/2011 5:57:16 PM. GUEST Thanks a Lot;) 3/8/2011 4:29:55 AM.
Simple Calculator Program In Android Studio
GUEST I needed to understand listbox arrays (and how to manipulate them) and couldnt find the specific help I needed so I'm using this tutorial to help me understand how to manipulate arrays in general. I have followed the examples as given, but the command operator (+) just displays the first and second number, it does'nt add them together, it just displays which numbers were selected. All other operators work as expected. Looking at the code, I cant see why this would be, it's supposed to add them both together and give the result. It's indicative of a problem I had with another project I was working on. It required arrays in listbox form.
The problem I was having there was I only wanted calculations happening to 1 element of the array when selected from the form, the problem being all elements of the array would chime in with their calculations, even when just trying to manipulate just 1. I clearly have a problem with arrays I just dont understand how to work with them. Was wondering if (with the above explantion in mind) you could point me to a resource which explains to the beginner how to manipulate and work with arrays?
I have looked, but I have yet to find a resource which is specific enough for me to use as an example. Thanks for any help. 3/9/2011 9:40:42 PM. pons The reason why the (+) operator fails can be due to the datatype mismatch. You may change the following line from - Text1.Text = Text1.Text + Command1(Index).Caption to Text1.Text = cInt(Text1.Text) + cInt(Command1(Index).Caption) This will cast both the strings to integer before applying the specific operation. BTW which version of visualbasic are you using?
You may refer to the following MSDN Link for more information on arrays Feel free to discuss here. It will help future readers who may have encountered the same issue as you. 3/9/2011 11:00:04 PM. GUEST Hi, thanks for the response. I'm using VB6. I know I should be using a later version but I've only just started with this stuff (I had a copy of VB6 lying around and it was quicker to get going with that). I really am a rank newbie but I have managed to develop one number crunching app and purposely steered clear of arrays to do it.
My coding is naieve to say the least. I dont yet know the shorthand way to code variables and arrays so I end up doing lines of basic looking code for every possible combination of events (haha - the caveman approach to developing!). I should have mentioned earlier I was referring to multi select listbox arrays. I have a specific problem. It would take me forever to explain it the way it occurs in my head so it would probably be better for me just to throw the code up, explain the situation and let you see whats happening.
