Introduction

I am just trying to explain, how can use "ean13.tff" font in c#.net.
First you downlaod / copy (from your source folder) ean13.tff font.
Then install this font your font directory ( C:\Windows\fonts). Then try to run project or
WINFOnt.exe file .

Using the code

In my sample Code have two methods

1. EAN8(string chaine)

public string EAN8(string chaine)

{

int i;

double checksum;

string CodeBarre = "";

checksum = 0;

if (chaine.Length == 7)

{

for (i = 1; i <= 7; i++)

{

int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));

if ((L1 < 48) || (L1 > 57))

{

i = 0;

break;

}

}

if (i == 8)

{

for (i = 7; i > 0; i = i - 2)

{

checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));

}

checksum = checksum * 3;

for (i = 6; i > 0; i = i - 2)

{

checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));

}

chaine = chaine + (10 - checksum % 10) % 10;

CodeBarre = ":";

for (i = 1; i <= 4; i++)

{

CodeBarre = CodeBarre + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

}

CodeBarre = CodeBarre + "*";

for (i = 5; i <= 8; i++)

{

CodeBarre = CodeBarre + Convert.ToChar(97 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

}

CodeBarre = CodeBarre + "+";

}

}

return CodeBarre;

}

EAN13(string chaine)

public object EAN13(string chaine)

{

object functionReturnValue = null;

int i;

int checksum = 0;

int first;

string CodeBarre;

bool tableA;

functionReturnValue = "";

if (chaine.Length == 12)

{

for (i = 1; i <= 12; i++)

{

int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));

if (L1 < 48 || L1 > 57)

{

i = 0;

break;

}

}

if (i == 13)

{

for (i = 12; i >= 1; i += -2)

{

checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));

}

checksum = checksum * 3;

for (i = 11; i >= 1; i += -2)

{

checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));

}

chaine = chaine + (10 - checksum % 10) % 10;

CodeBarre = chaine.Substring(0, 1) + Convert.ToChar(65 + Convert.ToInt32((chaine.Substring(1, 1))));

first = Convert.ToInt32(chaine.Substring(0, 1));

for (i = 3; i <= 7; i++)

{

tableA = false;

switch (i)

{

case 3:

switch (first)

{

case 0:

case 1:

case 2:

case 3:

tableA = true;

break;

}

break;

case 4:

switch (first)

{

case 0:

case 4:

case 7:

case 8:

tableA = true;

break;

}

break;

case 5:

switch (first)

{

case 0:

case 1:

case 4:

case 5:

case 9:

tableA = true;

break;

}

break;

case 6:

switch (first)

{

case 0:

case 2:

case 5:

case 6:

case 7:

tableA = true;

break;

}

break;

case 7:

switch (first)

{

case 0:

case 3:

case 6:

case 8:

case 9:

tableA = true;

break;

}

break;

}

if (tableA)

{

CodeBarre = CodeBarre + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

}

else

{

CodeBarre = CodeBarre + Convert.ToChar(75 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

}

}

CodeBarre = CodeBarre + "*";

for (i = 8; i <= 13; i++)

{

CodeBarre = CodeBarre + Convert.ToChar(97 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

}

CodeBarre = CodeBarre + "+";

functionReturnValue = CodeBarre;

}

}

return functionReturnValue;

}

AddOn(string chaine)

public string AddOn(string chaine)

{

int i;

int checksum = 0;

string AddOnn = "";

bool tableA;

if (chaine.Length == 2 || chaine.Length == 5)

{

for (i = 1; i < chaine.Length; i++)

{

int L1 = Convert.ToChar(chaine.Substring(i - 1, 1));

if (L1 < 48 || L1 > 57)

{

break;

}

if (chaine.Length == 2)

{

checksum = 10 + Convert.ToInt32(chaine) % 4;

}

else if (chaine.Length == 5)

{

for (i = 1; i == 5; i = i - 2)

{

checksum = checksum + Convert.ToInt32(chaine.Substring(i - 1, 1));

}

checksum = (checksum * 3 + Convert.ToInt32(chaine.Substring(2, 1)) * 9 + Convert.ToInt32(chaine.Substring(4, 1)) * 9) % 10;

}

AddOnn = "[";

for (i = 1; i <= chaine.Length; i++)

{

tableA = false;

switch (i)

{

case 1:

int[] str = { 4, 9, 10, 11 };

for (int j = 0; j < str.Length; j++)

{

if (str[j] == checksum)

{

tableA = false;

break;

}

}

break;

case 2:

int[] str1 = { 1, 2, 3, 5, 6, 7, 10, 12 };

for (int j = 0; j < str1.Length; j++)

{

if (str1[j] == checksum)

{

tableA = false;

break;

}

}

break;

case 3:

int[] str2 = { 0, 2, 3, 6, 7 };

for (int j = 0; j < str2.Length; j++)

{

if (str2[j] == checksum)

{

tableA = false;

break;

}

}

break;

case 4:

int[] str3 = { 1, 3, 4, 8, 9 };

for (int j = 0; j < str3.Length; j++)

{

if (str3[j] == checksum)

{

tableA = false;

break;

}

}

break;

case 5:

int[] str4 = { 0, 1, 2, 4, 5, 7 };

for (int j = 0; j < str4.Length; j++)

{

if (str4[j] == checksum)

{

tableA = false;

break;

}

}

break;

}

if (tableA)

AddOnn = AddOnn + Convert.ToChar(65 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

else

AddOnn = AddOnn + Convert.ToChar(75 + Convert.ToInt32(chaine.Substring(i - 1, 1)));

if ((chaine.Length == 2 && i == 1) || (chaine.Length == 5 && i < 5))

AddOnn = AddOnn + Convert.ToChar(92);

}

 

}

}

return AddOnn;

}
