@Tim Sir I want to code it using pointers and by far there is no conversion directly from octal to hexadecimal.So it is not dat simple..... @Richard I read books n found out that there is no direct conversion and if u have read it properly i want the code in C not in .NET as the libraries are totally different.

Can somebody help me to write code for converting a hexadecimal no. to octal no. using pointer in C.I am not getting how to accept a hexadecimal no. from user and how to convert it in to octal equivalent using C.Thanking you in advance.

Hi I wrote the code for adding image as well as saving the image but whenever I add photos and save them the original size of the photos gets reduced.It takes size of 80,80 I commented the line but still the size of the photos is 80,80 Can somebody pls help...... //to add photos private void btnAddPhotos_Click(object sender, EventArgs e) { openFileDialog.Filter = "Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*"; openFileDialog.Multiselect = true; if (openFileDialog.ShowDialog() == DialogResult.OK) { listView1.View = View.LargeIcon; //imageList.ImageSize = new Size(80, 80); for (int c = 0; c < openFileDialog.FileNames.Length; c++) { Image i = Image.FromFile(openFileDialog.FileNames[c].ToString()); Image img = i.GetThumbnailImage(256, 256, null, new IntPtr()); imageList.Images.Add(img); } listView1.LargeImageList = imageList; int cntl = listView1.Items.Count; if (cntl == 1) { ListViewItem lstItem = new ListViewItem(); lstItem.ImageIndex = 1; listView1.Items.Add(lstItem); } else { for (int j = cntl; j < imageList.Images.Count; j++) { ListViewItem lstItem = new ListViewItem(); lstItem.ImageIndex = j; listView1.Items.Add(lstItem); } } } else { return; } } //to save photos private void btnSavePhotos_Click(object sender, EventArgs e) { clsImageSettings saveFileDia = new clsImageSettings(); clsImageSettings objSaveImage = new clsImageSettings(); FolderBrowserDialog objFolderDai = new FolderBrowserDialog(); string imgPath = ""; if (listView1.Items.Count > 0) { if (objFolderDai.ShowDialog() == DialogResult.OK) { imgPath = objFolderDai.SelectedPath; for (int i = 0; i < openFileDialog.SafeFileNames.Length; i++) { string imgFilePath = openFileDialo

After performing operations on mutiple images at the same time(batch image processing) I want to save the images in the same format as the original one.How can I achieve this Can someone pls help.

djsproject

can someone elaborate more on this.............

djsproject

can u give me an example to illustrate more

djsproject

can someone tell what third party components are and how can one integrate them in once programs?thanks in advance........

hello everybody i have one csharp .net code that selects multiple images.

string[] extensions = new string[] {"jpg", "gif", "bmp", /*...*/};
foreach (string extension in extensions)
{
FileInfo[] FileJpg = FileDirectory.GetFiles(string.Format("*.{0}", extension));
foreach (FileInfo File in FileJpg)
{
ImageList.Add(File.Name, File.FullName);
checkedListBox1.Items.Add(File.Name);
}
}

and a second code that performs rotation on one image.

namespace ImageRotation
{
public partial class Form1 : Form
{
private Image loadedImage;

    public Form1()
    {
        InitializeComponent();
    }

    private Image RotateImage(Image inputImg, double degreeAngle)
    {
        //Corners of the image
        PointF\[\] rotationPoints = { new PointF(0, 0),
                                    new PointF(inputImg.Width, 0),
                                    new PointF(0, inputImg.Height),
                                    new PointF(inputImg.Width, inputImg.Height)};

        //Rotate the corners
        PointMath.RotatePoints(rotationPoints, new PointF(inputImg.Width / 2.0f, inputImg.Height / 2.0f), degreeAngle);

        //Get the new bounds given from the rotation of the corners
        //(avoid clipping of the image)
        Rectangle bounds = PointMath.GetBounds(rotationPoints);

        //An empy bitmap to draw the rotated image
        Bitmap rotatedBitmap = new Bitmap(bounds.Width, bounds.Height);

        using (Graphics g = Graphics.FromImage(rotatedBitmap))
        {
            g.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.HighQuality;
            g.InterpolationMode = InterpolationMode.HighQualityBicubic;

            //Transformation matrix
            Matrix m = new Matrix();
            m.RotateAt((float)degreeAngle, new PointF(inputImg.Width / 2.0f, inputImg.Height / 2.0f));
            m.Translate(-bounds.Left, -bounds.Top, MatrixOrder.Append); //shift to compensate for the rotation

            g.Transform = m;
            g.DrawImage(inputImg, 0, 0);
        }
        return (Image)rotatedBitmap;
    }

    private void trackBar1\_Scroll(object sender, EventArgs e)
    {
        if (loadedImage != null)
            pictureBox1.Image = RotateImage(loadedImage, (double)tRotation.Value);
        pictureBox1.Refresh();
