Label printing using zebra printers

Hi,

A programmer who used to work in my position created an application in ASP.net & c# (web application) to print a label in zebra printer Ht-146. I am so new to this kind of application and not sure how he did that. I think he used EPL2 programming language to print it. Right now the printer company zebra has discontinued this printer and I am not sure where to get help from. I don't have their programmer's manual to learn the EPL2language. My question is, is there any way that i could preview the label before printing it. Below is the code to print the label:

public int printlabel(string field1, string field2){

StringBuilder sb = new StringBuilder(2500);

//O-Hardware oprions. O- Disable all the options

sb.Append("O" + Environment.NewLine);

//Q-will cause the printer to recalculate and reformat the image buffer.

sb.Append("Q1014,1" + Environment.NewLine);

//q-set label width.

sb.Append("q608" + Environment.NewLine);

//S-selects the speed of the printer

sb.Append("S3" + Environment.NewLine);

//D-Print density

sb.Append("D5" + Environment.NewLine);

//Z-Print orientation T-Prining from top of image buffer

sb.Append("ZT" + Environment.NewLine);

//JF-Top of the form back up feature

sb.Append("JF" + Environment.NewLine);

sb.Append(Environment.NewLine);

//N-Clears the image buffer prior to building a new label image

sb.Append("N" + Environment.NewLine);

//LE-Line draw exclusive

sb.Append("LE305,2,1,1013" + Environment.NewLine);

//X-Draws a box shape P1-Horizontal start position P2-Vertical start position P3-Line thickness

//P4-Horizontal end position P5-Vertical end position

sb.Append("X305,507,1,458,1016" + Environment.NewLine);

sb.Append(Environment.NewLine);

sb.Append("X305,0,1,458,509" + Environment.NewLine);

sb.Append(Environment.NewLine);

//A -Command(ASCII), P1-Horizontal start position P2-Vertical Start Position P3-Rotation (3-270 degrees)

//P4 - Font Selection P5- Horizontal multiplier P6 - Vertical multiplier N-Normal or R-Reverse image.

sb.Append("A10,1009,3,3,1,1,N,\"PART NO. AND ITEM DESCRIPTION\"" + Environment.NewLine);

//LE-Line Draw Exclusive P1-Horizontal start position P2-Vertical start posiion P3-Horizontal length in dots

//P4-P4-Vertical length in dots

sb.Append("LE83,38,1,508" + Environment.NewLine);

sb.Append("LE83,38,1,508" + Environment.NewLine);

sb.Append("A109,1010,3,3,1,1,N,\"PN: " + field1 + "\"" + Environment.NewLine);

sb.Append("A133,1010,3,3,1,1,N,\"\"" + Environment.NewLine);

sb.Append("A157,1010,3,3,1,1,N,\"\"" + Environment.NewLine);

sb.Append("A181,1010,3,3,1,1,N,\"" + field2 + "\"" + Environment.NewLine);

sb.Append("A205,1010,3,3,1,1,N,\"\"" + Environment.NewLine);

printString = sb.ToString();

sendBytes = Encoding.ASCII.GetBytes(printString);

strlength = printString.Length;

try

{

TcpClient printer = new TcpClient(ip,portno);

NetworkStream strm = printer.GetStream();

strm.Write(sendBytes, 0, strlength);

strm.Close();

printer.Close();

}

catch (Exception exc)

{

return -1;

}

return 1;

}

Can anyone explain me whether there is any way to preview this label before printing it?
Is it possible for me to preview the label just by installing the print driver without the printer itself?
I would really appreciate your help.

NOTE: We have Bar-one software to create the label but not sure how to do that.
Thanks

i have one document which describes the PCL of zebra printers, let me know your mail id, so that i can mail that to you.

Ninety-eight percent of the thrill comes from knowing that the thing you designed works, and works almost the way you expected it would. If that happens, part of you is in that machine.

Hi,
I have 3 questions.

1: How to Get sql numeric datatype in C#.Net

Exp:

dr.GetInt32(); // What will here

2:I have a combox which bind with a default View Manager and i set properties of combox like this:

adpclientinfo.Fill(dsclientinfo);
this.dviewmgrclient = dsclientinfo.DefaultViewManager;
this.cbclientname.DataSource = this.dviewmgrclient;
this.cbclientname.DisplayMember = "Client_Info.Client_Name";
this.cbclientname.ValueMember = "Client_Info.Client_Name";
this.txtclientcode.DataBindings.Add(new System.Windows.Forms.Binding("Text", this.dviewmgrclient, "Client_Info.Client_Id"));

Now i get value from db table and i want to select(mean select index or any other) same value from combox.

I use this.cbclientname.selectedValue = dr.GetString(0); //Client Name

(1) dr.GetInt32(index);
or Convert.Int32(dr.GetValue(index));
index being the index of the column in a particular record.

(2) this.cbclientname.selectedValue = dr.GetString(0); //Client Name
wont work. You will have to assign the actual object from the list.
The workaround is to set the text property.

this.cbclientname.Text = dr.GetString(0);

The combobox will automatically try to find a match from the datasource and if a
match is found SelectedIndex changes automatically.

this.cbclientname.Text = dr.GetString(0);

========================================
I get Value from GetString(0) is SK Technology and in combox it exits in second index i want to select SK Technology. which property of combox work.

1: SelectedItem
2: SelectedText

You should just set the Text property.
Setting the SelectedItem to work you must set the value to an actual object(not just text) from the source list.

Installer project help

Hello, I have created a Solution in C#.Net which consists of 3 separate
projects and numerous dependency files which are organized into
directories such as databases, images, usage files, etc. When the
program runs, it searchs for the various files it needs in each of
these directories. I am now working on creating an Installer project
for this Solution so that it may be simply installed on a user's
computer. I have added all of the necessary files to this
Installer/Set-up project and I see that it is possible to specify where
these files are installed onto a new computer but changing the "Folder"
property for each dependency to either "Application Folder", "User's
Desktop", or "User's Programs Menu". I would like to know how I can
specify that a dependency file be installed to a custom location such
as "Application Folder/images/". There must be some simple way to do
this that I am just missing. Any help would be much appreciated.
Thank you.

If I'm coding an RSS reader in C#, what's the method by which I can tell whether or not this specific item in this feed is new or not? There are no ID tags in the Item XML element in the feed. How can I tell whether or not the user has already downloaded this item?

Most of the RSS feeds have a guid element (under the item tag). If it's not available, you're out of luck, you can probably make do with the value in the link tag.

I am trying to drill down a xml file having schema reference in c# .NET and while processing have added namespace using XmlNamespaceManager but it still gives error "Namespace Manager or XsltContext needed. This query has a prefix, variable,or user-defined function." Following is the code snippet

-----------------code snippet-----------------------------------------
XmlDocument objDoc = new XmlDocument();

Hi Neel07,

The Problem is the line:
objXmlNS.AddNamespace("xmlns:OrigoNS","http://www.origoservices.com");

You register the namespace uri http://www.origoservices.com with the prefix xmlns:OrigoNS. But you request uses the prefix OrigoNS only.

Simple use following line:
objXmlNS.AddNamespace("OrigoNS","www.origoservices.com");

Good Luck!

Thanks a lot

I have found the solution and you are right we should mention only "OrigoNS" as namespace prefix. Also it should call the 1st overloaded method of SelectSingleNode passing the XmlNamespaceManager object in the 2nd parameter.

Corrected code
XmlDocument objXmlDoc = new XmlDocument();
objXmlDoc.Load("C:\\abc.xml");
objRoot=objXmlDoc.DocumentElement;

XmlNamespaceManager objXmlNS = new XmlNamespaceManager(objXmlDoc.NameTable);
objXmlNS.AddNamespace("OrigoNS","http://www.origoservices.com");

XmlNode objRoot;
string MsgID=objRoot.SelectSingleNode("//OrigoNS:message_id",objXmlNS).InnerText;

Error message with AutoNumber column issue- update DB

1-Aug-05 2:16

I implemented article “Inserting relational data using DataSet and DataAdapter” from this link: http://www.codeproject.com/cs/database/relationaladonet.asp[^] In my code.
It has a perfect explanation; still I got stuck at one point.
Debugger shows when that when I’m at this stage:

static void CustDataAdapter_OnRowUpdate(object sender, OleDbRowUpdatedEventArgs  e)
		{
			OleDbCommand custCmd = new OleDbCommand("SELECT @@IDENTITY", e.Command.Connection);   //right after this line
			e.Row["CustID"] = custCmd.ExecuteScalar();
			e.Row.AcceptChanges();
		}

This method defines the OleDbRowUpdatedEventHandler event, which comes to solve the AutoNumber column issue.

I got a message box error:

Problem populating dataset Box: [System.NullReferenceException: Object reference not set to an instance of an object at (object sender, OleDbRowUpdatedEventArgs e) in [path to file name]

There is some more text below it, but this seems to be the main thing. Why do I get NullReferenceException? What did I missed?

Hi,

I want to have to different login sections. One section for customer login, and the other login for administrators. Customers should login at wwwroot/customer/login.aspx, and administrators should log in at wwwroot/admin/login.aspx. Is it possible to have this in the webconfig file, what I mean is, if the user tries to access a page in one of these two sections the he/she will be directed to the correct login section? Is the web config file the correct way to do? Will it be able to keep track if the user is logged in or not?

Where can I get decent articles to read about the webconfig file?

All help is appreciated!!

Thanks

My question to you is how are you going to find out if the user is an admin or a customer until the credentials are typed in. The routing may/should only happen after that.
