View 2 RepliesI 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.
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 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:

I 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 RepliesI'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).

Okay so here's the question how do I get the links that open in a new window to open in my main webbrowser control. The above code does some, but it's not fool proof.
I want to open up an existing instance if my program is already running only if its running the same version.I noticed that this question was asked for only if the name exists, but what if the version is older, I just want to notify the user that an older version is still running, "please remove older version before starting this version."The other link is this one:Return to an already open application when a user tries to open a new instance but they don't talk about closing an instance if an older or newer version is detected.

View 1 RepliesI've noticed that when you click on a web page in Windows Explorer, or open a file in general, and the default application to open it is internet explorer, ie opens and opens the file. However, when I tried this on my Web Browser it opened, but ignored the file and went on its usual routine. How can I get my Web Browser to open and open the file that was clicked on in explorer?

I saved a file with the extension .doc. I use the RichText to write and save the text. I did not set any encoding type when I saved it. When I tried to open the file in the Richtextbox again, I got all the formatting characters in the RTF file. How do I correct this? How do I open and re-open a .doc file in the Rich Text box control without the formatting showing up in the box with the document contents?

View 8 RepliesI have a function on my program that allows a user to load a listbox filled with words that are matched with words inside a databank. The databank is filled with 2 string arrays and file of .jpg Pictures. The Arrays attached to each word inside the listbox are approximately one page. Each page is two paragraphs of Text(string Array) and one Picture(20Kbytes).My problem is this. When the user selects the option print all, the listbox with approximately 10255 words is selected and begins to fill a Microsoft Word Document.Because the alotted amount of space needed for the MS Word Document is approximately 5 Gbytes,I need to open about 10 Documents and insert the String Array's and Pictures into each document one at a time.Is there anyway to check the filesize of the Open Document before saving the document.This way I could check the open document inside the algorithm for 512 Mbytes of memory and save the document before the size gets above 512 Mbytes.[code]

View 1 RepliesI have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.
Unfortnately, I cannot get it to work for more than one file.
System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened
System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.
