Following are the methods to generate the barcode using C-Sharp...
private void
btn_GenerateBarCode_Click(object sender, EventArgs e)
{
GenerateBarCode();
}
private void
GenerateBarCode()
{
int barSize
= System.Convert.ToInt32(39);
System.Byte[] imgBarcode = Code39("*" + txtBarCodeText.Text + "*",
barSize, false, "");
MemoryStream
memStream = new MemoryStream(imgBarcode);
PictureBox_BarCodeResult.Image = new Bitmap(memStream);
//statbar.Panels[0].Text
= "Done.";
this.Cursor
= Cursors.Default;
}
// This Method is
used in above method
public byte[]
Code39(string code, int
barSize, bool showCodeString, string title)
{
MyBarCodeClass
c39 = new MyBarCodeClass();
string
appPath = Path.GetDirectoryName(Application.ExecutablePath);
// Create
stream....
MemoryStream
ms = new MemoryStream();
c39.FontFamilyName = "Free 3 of 9";
c39.FontFileName = appPath + "\\FREE3OF9.TTF";
c39.FontSize = barSize;
c39.ShowCodeString = showCodeString;
if (title +
"" != "")
c39.Title = title;
Bitmap
objBitmap = c39.GenerateBarcode(code);
objBitmap.Save(ms, ImageFormat.Png);
//return
bytes....
return
ms.GetBuffer();
}
