How to Add the values of List into the List after encoding it to Barcode in c#

Question

I have two List one is of string and the other is of PictureBox type. I want to take the values of List of type string and the convert it into the Barcode then save it to th

Answer 1

I believe, if bar1.Encode actually has return type of Image, this lines in PrintButton_Click method :

PictureBoxList[j].Image = bar1.Encode(barcodetype1 ,SerialNumberList[j]); // It gives me exception of Index out of range
PictureBoxList.Add(PictureBoxList[j]);

should be like this :

var pictureBox = new PictureBox();
pictureBox.Image = bar1.Encode(barcodetype1 ,SerialNumberList[j]); 
PictureBoxList.Add(pictureBox);

UPDATE :

To make it clear, my answer above meant PrintButton_Click should be as follow :

private void PrintButton_Click(object sender, EventArgs e)
{
   for(int j =0 ; j < SerialNumberList.Count ; j++)
   {
        BarcodeLib.TYPE barcodetype1 = BarcodeLib.TYPE.CODE39;
        BarcodeLib.Barcode bar1 = new BarcodeLib.Barcode();
        bar1.IncludeLabel = true;
        var pictureBox = new PictureBox();
        pictureBox.Image = bar1.Encode(barcodetype1 ,SerialNumberList[j]);
        PictureBoxList.Add(pictureBox);
        printDocument1.PrintPage += new System.Drawing.Printing.PrintPageEventHandler(printDocument1_PrintPage);
        printDocument1.Print();
   }
}

Answer 2

mean you have string and you have converted it to barcode. finally we have a property in barcode which holds the value of string right?? now you want to display that string as image??

if so then refer the below code -

    public Image stringToImage(string inputString)
    {
        string text = inputString.Trim();

        Bitmap bmp = new Bitmap(1, 1);

        //Set the font style of output image
        Font font = new Font("Arial", 25, FontStyle.Regular, GraphicsUnit.Pixel);

        Graphics graphics = Graphics.FromImage(bmp);

        int width = (int)graphics.MeasureString(text, font).Width;
        int height = (int)graphics.MeasureString(text, font).Height;

        bmp = new Bitmap(bmp, new Size(width, height));
        graphics = Graphics.FromImage(bmp);



        //Specify the background color of the image
        graphics.Clear(Color.Cyan);
        graphics.SmoothingMode = SmoothingMode.AntiAlias;
        graphics.TextRenderingHint = TextRenderingHint.AntiAlias;



        //Specify the text, font, Text Color, X position and Y position of the image
        graphics.DrawString(text, font, new SolidBrush(Color.Black), 0, 0);
        graphics.Flush();
        graphics.Dispose();

        //if you want to save the image  uncomment the below line.
        //bmp.Save(@"d:\myimage.jpg", ImageFormat.Jpeg);

        return bmp;
    }

Answer 3

you want like this.. right?? see this is the representaion of the this string "S1253551" in 3of9 and plain text and finally as image right??

    public Image stringToImage(string inputString)
    { 
        string text = inputString.Trim();

        Bitmap bmp = new Bitmap(1, 1);

        //Set the font style of output image
        Font font = new Font("Free 3 of 9", 25, FontStyle.Regular, GraphicsUnit.Pixel);
        Font font2 = new Font("Arial", 15, FontStyle.Regular, GraphicsUnit.Pixel);

        Graphics graphics = Graphics.FromImage(bmp);

        int width = (int)graphics.MeasureString(text, font).Width;
        int height = (int)graphics.MeasureString(text, font).Height;

        int height2 = (int)graphics.MeasureString(text, font2).Height;

        bmp = new Bitmap(bmp, new Size(width, height+height2));
        graphics = Graphics.FromImage(bmp);



        //Specify the background color of the image
        graphics.Clear(Color.Cyan);
        graphics.SmoothingMode = SmoothingMode.AntiAlias;
        graphics.TextRenderingHint = TextRenderingHint.AntiAlias;



        //Specify the text, font, Text Color, X position and Y position of the image
        graphics.DrawString(text, font, new SolidBrush(Color.Black), 0, 0);
        graphics.DrawString(text, font2, new SolidBrush(Color.Black), 0, height);

        graphics.Flush();
        graphics.Dispose();

        //if you want to save the image  uncomment the below line.
        //bmp.Save(@"d:\myimage.jpg", ImageFormat.Jpeg);

        return bmp;
    }

Remember you must have installed "free 3 of 9" font.

you pass the string "S1253551" and it generate the barcode and add the plain text at bottom and finally return it as image.

Its working code i have tried at my end. Enjoy. :)
