Prob 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.
Prob 2: To solve Prob 1, I removed the try..catch block and all the error messages BUT.. now my cash drawer does not OPEN.
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]...
I have a USB cash drawer that acts as a com port (lets assume com2)
any ideas on how I can open it? there is not really any documentation with it.
I 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:
[Code]...
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).

View 1 RepliesCan anyone recommend a POS receipt printer that would integrate easily to a .NET WinForms application?Basically what I mean by integrate easily, is that the printer would actually show up as a standard windows printer, because the existing application uses Microsoft reporting services to print receipts, and I do not want to have to redo the entire receipt process via some SDK or API exposed by some proprietary receipt printer.Right now the client is printing on 8.5x11 sheets of paper from a standard printer, and it is just silly to use such big paper for receipts.We thought about getting half sized paper, since the current laser printer tray supports it, but found that non standard paper sizes run much more expensive than standard size paper, and it is not worth it.So I will tweak the report layout to fit a smaller size once I have a printer in place to use, so I am just looking for a recommendation if anyone has worked with any specific POS receipt printers.

View 4 RepliesI'm trying to check the printer status of a shared printer on a Win98 platform pc and need some samples to get started.
View 3 RepliesBasically, 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))

I have printer vendor provided SDK implementing that i can get printer DEVMODE or HDC with correct printer settings.
My questions is:
I am already using printDocument to print the image (System.Drawing.Bitmap). How can send use this HDC or DEVMOD with printDocument.
I already tried using the "PrintDocument.SetDevMode". it seems not be working.
1. Detect if my printer is busy, because my code tells the printer to print more pages that it can cope with, so I need to delay the command for 'Print the next page' until the printer has finished printing the previous one.
2. Shift the output to my printer so that it gets printed in it's entirety on the paper, instead of seemingly being anchored to some nebulous point on the A4 page. It starts printing at X = 29mm from the left edge, and Y is 28mm from the top, and stops at X = 22mm from the right edge and Y stops at 22mm from the bottom edge, leaving (aprox) 50mm of X and 50mm of Y unprinted.
3. Get useful information on Bounds, which I'm fairly certain is what I need to control where my printing should start and finish.
I've hunted through this forum, MSDN, 'Help' (a misnomer if ever there was one) the VB Library and one or two other forums, which either baffle me with reams of code or suggest code to try which either just don't work or which doesn't declare all the variables and usually don't suggest what type of variable I need, it's all very frustrating

I am programmatically "reading" e-mails using WebDav. I am also deleting these e-mails when I've finished having my way with them, however, this is causing an interesting problem. Each time I delete an e-mail the original sender is getting a not read response. I have logged into OWA and checked the option Do not automatically send a response but this doesn't seem to help.Is there ANY way to remove the request for read receipt from the e-mail before deleting it?
