My assignment this week is to create a simple cash register. The kicker here is that I have to have an input box pop up to accept the data. I know I need to use a Do Loop here, but I' not sure what the proper condition should be. Hitting cancel on the input box or inputting nothing ought to terminate the loop.
Private Sub btnCheckout_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnCheckout.Click
Static decPrice As Decimal
Static intCount As Integer
Static decSub As Decimal
I'm trying to convert an ancient cash register program to .net. Conquered everything else, but I can't pop open the cash register. Its connected to COM1, you are supposed to send a "trigger" text down COM1 that will cause the register to open.
Here is the .net code. MsgBox("Opening Drawer") Dim port As System.IO.Ports.SerialPort port = New System.IO.Ports.SerialPort("Com1") port.PortName = "COM1" port.BaudRate = 9600 [Code] .....
I get msgboxes "Signal Sent", "Done Pop Drawer". It just won't pop. It's an MS-Cash Drawer (EP125KC). Definitely connected to COM1, definitely has power. Chr(65) is the old code used to pop drawer and it works: Open drawerComPort For Output Access Write As #1 Print #1, Chr$(65); "A"; Close #1 The above code worked successfully. The root problem was caused by a reversed power cord (negative was on the wrong side).
Im getting mathematical errors. the part that I'm having problems with is, first, it doesn't add the tax to total the correct way. It adds it correctly if I put a dollar(1.00) but when I type one hundred dollars (100.00) it doesn't add the tax correctly. I am trying to compute and display the tax on the new subtotal. Second, it is not adding the correct change to the label in dollars, quarters, dimes, nickels, and cents. Third my arithmatic is not adding correctly when it has to do with the change due back. . Finally, forth I am also trying to do the following:
* add the total for this item to the order sub total and display the new subtotal.
* I have 2 clear buttons, one clears item, the other clears order the clear order button shoule clear out the change due and bordered label and have the subtotal reset to $0.00. The clear item should just clear out the quantity, unit price, and item total textbox.
* When the user has entered the amount of money tendered by the customer and click calc order button, the program should use the amount tendered and the current order total to compute and display the change due to the customer.
* the change due should be displayed in currency format in the readonly label, and should be displayed in terms of the number of dollars and coins due in the bordered label. [code]
I am writing a program that sims a cash register. Everything works fine except VB will not compute subtraction. If I put a replace - with + everything works. What could be the cause of this?
Here is part of the
'Convert input into number isConverted = Double.TryParse(owedTextBox.Text, NumberStyles.Currency, NumberFormatInfo.CurrentInfo, owed)
[CODE]...
***********If owed is 10 and paid is 5, it returns 0, but if I change the - to either a + or *, it returns the expected value
I have this cash register program with separate forms for the items and the display form. The code works untill you press the button 2x. It says 5.5 + 5.5 = 11.5??? Can you fix this code?
CashReg.ListBox1.Items.Add("Item 1") Dim cash As String cash = (5.5)[code]....
I am trying to create a socket class in my project to send data to ecr (electronic cash register).Ecr comes with software that listens for commands on port 3535. Command are in forms of XML Files. It has only one catch, I must close the connection on socket, so the ecr would know when to process the command and respond. Since I only send one command at a time,I need the simplest solution I can get.
How it works:I create the socket and connect it to 192.168.1.67:3535 I start
client.BeginReceive
Then I send the command with
client.BeginSend
And I do a
client.Disconnect(True)
so I can get response from ECR.And in 8 of 10 times it works just fine. The problem is this few times it doesn't work.At that time I cant receive anything because it reports that the client is not connected in ReceiveCallback but it still manages to send the data to ECR just fine. The bill comes out on the ECR, but I get no answer about what happened.
I call the class like this:
Dim dre As New HCPSocket Result2 = dre.Otkucaj(Command1, "192.168.1.67") Debug.Print(Result2) dre = Nothing
End the class looks like this:
Imports System Imports System.Net Imports System.Net.Sockets
i am pulling together a cash register that will allow both bar code product entry and manual key entry.imagine if you have a tin of beans in front of you, in a small corner shop they would probably type "47" and then hit "Produce". Fairly straight forward as I have the button Produce to act upon my code and update my salestrans.mdb but,if you scan the bar code I want the same form to handle both 'real' actions, (i assume that keyboard emulation barcode scanner includes "ENTER" after providing 13 digits)....
Q. in perhaps a long winded way i want to know how to kick off an event based on the "ENTER" key being activiated by the barcode scanner)?i do not want to have to hit any buttons if i am scanning bar codes.

I'm wondering, is it possible to create a (REALLY) simple web server in VB.NET? I may be wrong, but don't you essentially just need a listener for port 80 and a way to send pages to the client?
Im trying to create a program with a simple gui that enables me to search for and select parent folders containing child folders containing multiple files and then validate those files based off of constants i set per child folder and file.
Example
User selects Parent FolderX Parent FolderX > (ChildFolder1 ( Constant for ChildFolder1 says open file 4 ) > File 4
Compare multiple strings of text in a specific order based off of file name to constants i have set for that named file Then continue to ChildFolder2 ( Constant for ChildFolder2 says open file 16 ) > File 16 Compare multiple strings of text in a specific order based off of file name to constants i have set for that named file If there is any constants not read in one of the files after all have been checked, return msgbox with a notification and write .txt log with child folder and file names to specified directory?

I just want to be able to click on a commandbutton, menu_item, or maybe even a wizard at program install time, to make the database from scratch.
1) I do not care what type of database it is it is as long as it will run on any pc machine without having other programs installed except the one im creating.
2) I do not want to use access or the designers to create the database either
I apologize if this question is something of the most simple, but I'm not even sure what terms I should use to search. What I'm trying to do is create a 'Sub' that will do something when I call it in another Sub, however I am unsure in how I would pass variables from one another. Here is what I have;
Private Sub Log LogBox.AppendText(logstuff & vbNewLine) End Sub
I am a beginer and I am trying to create a simple web browser using Visual Basic 2005 Express Edition.
Public Class Form2 Private Sub Button3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs)
[Code].....
As you can see from the above code I do not have forward, back and stop buttons. Thats because I do not need them. The browser will be configured to go to a certain website directly.
What I need is this browser should be configured to use specific JRE. That is the browser should use ONLY JRE 1.3.1 or ONLY JRE 1.4.2
I am currently painting a light blue, partly transparent overlay over owner-drawn objects to indicate certain state. It's OK but I thought that it would be even nicer if I could at some sort of glass effect to further establish the idea that the particular object has "something" overlaid over the top of it.
I thought that some glass streaks, for example, in addition to the blue transparency would lend a nice effect.I've Googled around for GDI+ (and others) algorithms to do simple things painting like this but have come up empty. I prefer .NET but can figure out the painting from pseudo-code on up.
Sorry, shoul've also specified that I need to target WinXP and using .NET version 2.0 - So unable to use WPF or Vista/Win7 goodies.

I want to create a new module in DNN (VB) ... that;
1. does not use DAL or DAL+
2. has only one view.ascx control
3. It has to be a compiled module
I do not need DB connectivity and any bells and whistles just one view control. I thought it would be simple but googling for a day now and it seems very complicated.
