Open Cash Drawer For Receipt Printer TM-U220?
Apr 29, 2010Prob 1: While the printing is going on, the whole system hangs. I would like the printing to go on while in spooling and not monitor its status.

Below is the whole set of code I used for testing. It is really very urgent request. (This code makes the whole system hang till printing is complete)[code]...
Check Whether Or Not The Cash Drawer Is Closed
Dec 16, 2009I am still working on a POS application in VB.Net 2003. What I need to do is check the state of the cash drawer. I want to make sure the drawer is closed before a cashier is allowed to move on to the next sale. The cash drawer I am using is a MMF ECD200 (not sure if this will make a difference). Here is the code I am using to open the drawer:

Cash Register Program - Opening Drawer?
Feb 9, 2010I'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).

View 2 RepliesSliding Drawer Effect In WinForms?
Mar 15, 2012I am looking to add a sliding drawer effect in a Winforms project.To explain myself further, I am looking to have a tab on the bottom of my form, then when the the tab is clicked the rest of the tab or tab control is shown. Any ways on how to do this or even having a docked tab will work as long as the docks/tabs width does not span across the whole form like all the other examples I have seen.I seen an example of a sliding panel when clicked by a button although I cant find the example anymore.
View 2 RepliesC# - If Not Check Then Add To Cash
Sep 9, 2011Basically, the code checks if the amount being entered is check. If it is check, insert the check value into chckval. If it is cash insert the cash value into cashval. So far, it is half working. It inserts the check into the check fieldname and inserts 0 into cash fieldname. What is not working is inserting cash into cash fieldname if the money is cash. It inserts the cash into cash fieldname as it should but it also inserts the same amount into check fieldname. This is not good. If it is cash and it is inserted into cash fieldname, I want check value to be 0.
Here is the latest code.
For x = 1 To 5 Step 1
dedval = Gridview1.FindControl("ded" & CStr(x))
chckval = Gridview1.FindControl("chck" & CStr(x))
chcknumval = Gridview1.FindControl("chcknum" & CStr(x))
checkboxval = Gridview1.FindControl("chckBox" & CStr(x))
[Code] .....
I think there is some issue with the
IF chckval.Text <> "" And Not checkboxval.Checked Then
statement

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.

View 9 RepliesMath / Change Return For A Cash Register
Feb 6, 2011Im 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]

View 4 RepliesReate A Socket Class In Project To Send Data To Ecr (electronic Cash Register)?
Jan 9, 2012I 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:

Forms :: Auto-Detect BarCode Scan Entry OR Manual Entry - Cash Register?
Sep 8, 2009i 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.
