Thread: Barcode Generator

I don't personally know how to create Barcodes, but this website should give you all the libraries and documentation that you would ever want: TWiki . Javapedia . Barcode

Dear aussiemcgr,

Thanks for the reply...I have done the coding in .Net when it comes to Java i have issues like code not getting executed correctly i have given part of the code here coz i cant produce the entire code right.....please have a look at the below code...

 
 
public class BarCodeVerifier {
	int nAPMCCode = 0; 
	int nDate = 0; 
	int nMonth = 0; 
	int nTime = 0; 
	int nTrader = 0; 
	int nLorry = 0; 
	int nCommodity = 0; 
	int nQuantity = 0; 
	int nMinute = 0;
	//String dt = DateFormat.getDateInstance().format(new Date()); // DateTime.Now.ToLongDateString();
 
 
 
	public BarCodeVerifier() {
	}
 
	public int[] GetDecodedData(String strCoded) {
 
		int[] nArr = { 1, 2, 3, 4, 5, 6, 7, 8, 9 };
		// strip the last char...
		char c = strCoded.toCharArray()[strCoded.length() - 1];
		if (strCoded.length() > 17) {
			String strMinuteCode = strCoded.substring(15, 17);
			int nMunite = (int) (Base36Decode(strMinuteCode));
			strCoded = new String(strCoded.substring(0, strCoded.length() - 3));
			nArr[8] = nMunite;
		} else {
			strCoded = strCoded.substring(0, strCoded.length() - 1);
			nArr[8] = 0;
		}
		// char c = strCoded.ToCharArray()[strCoded.Length-1];
		// strCoded = strCoded.substring(0,strCoded.length()-1);
 
		int nTime = (int) Base36Decode(String.valueOf(c));
		int nTemp = (nTime < 15) ? (15 - nTime) : (15 - (nTime - 15));
		strCoded = RotateString(strCoded, nTemp);
		nArr[0] = (int) (Base36Decode(strCoded.substring(0, 2))); 
		nArr[1] = (int) (Base36Decode(strCoded.substring(2, 3))); 
		nArr[2] = (int) (Base36Decode(strCoded.substring(3, 4))); 
		nArr[3] = nTime; // Time
		nArr[4] = (int) (Base36Decode(strCoded.substring(4, 7))); 
		nArr[5] = (int) (Base36Decode(strCoded.substring(7, 10))); 
		nArr[6] = (int) (Base36Decode(strCoded.substring(10, 12))); 
		// CODE
		nArr[7] = (int) (Base36Decode(strCoded.substring(12, 15))); 
 
 
 
		return nArr;
	}
 
	// Converts base36 string to int64 string .. All capitals
 
	public static long Base36Decode(String input) {
		/*
		 * This function converts the input String characters into base36 values
		 */
		String base36Chars = "0123456789ABCDEFGHIJKLMNOPQRSTUVWXYZ";
		char[] arrInput = new char[input.length()];
		arrInput=input.toCharArray();
		for (int i = input.length() - 1, j = 0; i != -1; i--, j++) {
			arrInput[j] = input.charAt(i);
		}
		long returnValue = 0, rv=0;;
		int value=1;
		for (int i = 0; i < arrInput.length; i++) {
 
			int valueindex = base36Chars.indexOf(arrInput[i]);
			if(i==0)
			{
				rv=valueindex;
			}
			else
			{
			for(int j=0;j<=i;j++)
 
			{
				   if(j==0)
					{
						value=1;
					}
					else
					{
					value*=36;
					}
 
			}
			returnValue+= valueindex*value;
			}
		}
		return rv+returnValue;
	}
	private String RotateString(String strRotate, int nTimes) {
		/*
		 * Function can Rotates the String
		 */
		char[] cTemp;
		char cur, nxt;
		int nLen = strRotate.length();
		for (int nIndex = 0; nIndex < nTimes; nIndex++) {
			cTemp = strRotate.toCharArray();
			cur = cTemp[0];
			nxt = cur;
			for (int nTemp = 0; nTemp < nLen - 1; nTemp++) {
				nxt = cTemp[nTemp + 1];
				cTemp[nTemp + 1] = cur;
				cur = nxt;
			}
			cTemp[0] = nxt;
			strRotate = new String(cTemp);
		}
 
		return strRotate;
	}
 
}

My code may not be correct...And my output is it should display me a barcode as of now and when i scan it,it should display me the details related to that barcode...As of now it should create me a barcode........Any Solution would be appreciable....Thanks in Advance....
