I am making a calculator for a school project, I want to have it so it looks similar to windows calc ( with one button for each number & only one text box),My code has a few blank spots but so far it is :
Public Class calc
Private Sub Btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Btn1.Click
IOBox.Text = IOBox.Text + "1"
End Sub
[code].....
so i am new to v basic and as you can see in the picture below that i have 2 textboxes just to put in them 2 numbers and then do mathematical calcualtions on them and a label up there that shows the answer so i wanted to make 1 textbox to type in the 1 st number then press the symbol for example + and then type the 2nd number and then press equal so the result is formed in the same textbox the only problem is idk how i searched google but i couldnt understand here is my source code

View 2 RepliesSo I am supposed to be choosing a final project for my visual basic 2008 class. I cannot help but remember an old high school classmate from web design class who made a program that used the speaker built into the motherboard (or whatever makes the start up beep when you turn computer on) to time the beeps to play simple songs. It was very funny and amusing and I was wondering if anyone had seen something similar or knows how to go about making one?
View 5 RepliesSo as the message says i believe im having a problem when declaring an array as control. The background:Im doing a school project where a picture is covered by 48 buttons. When a user clicks a button, they are asked a question. If they answer write, the button disappears until the whole image is displayed.
Im using each buttons visible property to hide it. Now that i think about it, i should probably un-enable it after a question is answered correctly.anyway, I keep getting a NullReferenceException when making the visible set to false. Any suggestions would be awesome. I have already created all the buttons and named them Q1-Q48.

Ok. I just took my final for VB and the last chapter we did was on procedures and functions. Functions was the only thing out of this whole semester that I was just completely lost. I'm trying to work on this cause I'm taking Advanced VB next so I wanna know what I'm doing. So I'm trying another tutorial in the book and I'm really lost. Here is what the it wants you to do.
Retail Price Calculator
Write an application that accepts from the user the wholesale cost of an item and its markup percentage. (For example, if an item's wholesale cost is $5 and its retail price is $10, then the markup is 100%)
The program should contain a function named CalculateRetail that receives the wholesale cost and markup percentage as arguments, and returns the retail price of the item.
When the user clicks the Get Retail button, the program should do the following:Verify that the values entered by the user for the wholesale cost and the markup percent are numeric and not negative. Call the CalculateRetail function Display the retail cost as returned from the function.
Here's what the calculator looks like and my code so far.
Public Class Form1
Private Sub btnRetail_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnRetail.Click

just Addition only at this time each number 0 to 9 have this code[code].....here what he says..Write the code for the equals button. There's only three lines in total, and here's a little help.
You need to use the other variable that was set up at the top of the coding window, total2. The variable total1 will be added to whatever is total2.The first line of code will be this
total2 = total1 + (something missing here)
Your job is to supply the missing code. In other words, replace "(something missing here)"
Remember that total1 contains the first number to be added. And you know where that came from. The only thing left to do is to add the second number.For the second line of code, you need to transfer the total2 variable to the textbox.For the third line of code, all you are doing is resetting the variable total1 to zero. That's because after the equals button has been pressed, we have finished adding up. If you wanted to do some more adding up, that total1 will still hold the value from the last time. If you reset it to zero, you can start adding some new numbers.

It's just a small calculator project so it's no big deal, but after I had built the project, I wanted to change the project name and all the file names that had that string in it (and all internal references to that string). I had played with this before and knew that it was asking for trouble but I thought, "What the hell, I'll try it again." feeling a bit brash.
Well, everything works fine in debug mode, but there is this DOS window that pops up just before the main form does, and it doesn't go away for the entire debugging session. I think I see that window pop up on all other projects too (if the main form doesn't cover it up completely), but normally, it's only there for a split second.
I'm very new at using Visual Studio (about 3 days!). I want to create a project that I created into an executable file. The help menu states that I should go under the 'File' drop down menu and select 'Make' to convert into an .exe format. However, the 'Make' selection is not present under the 'File' drop down menu. How can I make a project into an executable file??
