:confused: Please help me. I am writing a program in visual basic to create invoices for a future fictional buissness. I cannot find any sample code of cash registers. If you have any please tell me
:Thanx:

Re: Visual Basic

VB isn't my speciality, even though I do know some. What exactually do you want? Do you want a sort of interface like a cash register, code that processes functions that a cash register might have, etc.?

What do you mean by "sample code of cash registers"? Also, what edition and version of VB are you using? EE has a bunch of helpful controls. And how do you plan to store data about products? Like name, ID, price, etc. And what 'distribution' method are you going to do? LAN, DDE, multi form, what?

All of this effects what you use and how you do it.

I am using vb6.0

Re: Visual Basic

Can we see your code??? Or is it a secret?

Re: Visual Basic

are you compileing your variables before you try and sum them or is it an after affect

ie. function sample(x,y,z,p,d,q)

sum = x+Y+Z+P+D+Q

or
sum1 = x+y+z

sum2 = P+D+Q

Total = sum1 + sum2

i have found that doing inbetween steps like example 2 under each part of your program works better

Are you using Quanity textboxes, too?

say:

cbRC_Add as CommandButton
cbBat_Add as CommandButton
tbRC_Quanity as Textbox
lblRC_Total as Label
lblRC_Price as Label
tbBat_Quanity as Textbox
lblBat_Total as Label
lblBat_Price as Label
tbTotal as Label

These are the controls on your form.

So:

Code:

const RC_Price as currency = 500 'Sub type of variant

const Bat_Price as currency = 100

dim RC_Quanity as long, RC_Total as Currency

dim Bat_Quanity as long, Bat_Total as currency

dim Total as currency



private sub Form_Load ()

 RC_Quanity = 0

 Bat_Quanity = 0

 Update

end sub



Public sub Update()

 RC_Total = RC_Price * RC_Quanity

 Bat_Total = Bat_Price * Bat_Quanity

 Total = RC_Total + Bat_Total



 tbRC_Quanity = RC_Quanity

 tbRC_Total = RC_Total

 lblRC_Price = RC_Price

 tbBat_Quanity = Bat_Quanity

 tbBat_Total = Bat_Total

 lblBat_Price = Bat_Price

 tbTotal = Total

end sub

Be sure to insert Event hadlers for the command buttons and text boxes (Check for correct type).

Re: Visual Basic

I agree with Astronouth7303 200% what are you doing using a picture box!!!???!!?!!?!!? If you don't want people to be able to change the value then even using a label would be better then a picture box!

Re: Visual Basic

probably because he is using Print() so that he doesn't have to deal with linebreaks and the previous contents. however, i agree that a textbox is probably better here - the small amount of extra code is worth it.

i'd probably recommend a global variable to keep a running total in.

Re: Visual Basic

If you look at my code, I use variables for storing values and controls to display them. You could use the controls for storing values (VB handles conversions). But this introduces errors (possibly).

Re: Visual Basic

I just found something out about VB: it's predictable! :D lol

my brother (Bro) has been doing VC++ for a few months and has totally forgoten how to use VB, and I'm helping him make a control (Or: telling him he has to use "Not A" instead of "!A")

Hardly any (hopefully none) professional programmers would do this. Not only do you introduce the possiblity of introducing errors, it is less clean and violates a lot of principles of programming, such as information hiding.

P.S. VB gives me shivers. ;) Go Java and C++. :)
