Hi All,

I want to load an image(jpeg,png,..etc) from the hard disk and load it into image control in ASP.NET.
I prefer C# as the programming language.

After loading the image , i want to save the file location in a text file. Then the next time i can read the text file and i can get the image location[path]. I can do the same thing for the form application, but difficult to mange web applications[ASP.NET].

So simply what i need is; code segment for

-Browse an image file from the disk
-Load it into a image control[if resizing is possible, then good]
-then save the image location to a text file

can anybody help me to do this?

Thanks,
Charithmax

You can use the UploadControl to upload your images from asp.net. You can access the image bytes through .FileBytes and the file name through .FileName

Thanks Martins, I followed your instructions and found a good article. here is the link.

http://asp.net-tutorials.com/controls/file-upload-control/

this is the code segment....

--------------------File Upload Control--------------------------------------------------------------------------------------------

<form id="form1" runat="server">
    <asp:FileUpload id="FileUploadControl" runat="server" />
    <asp:Button runat="server" id="UploadButton" text="Upload" onclick="UploadButton_Click" />
    <br /><br />
    <asp:Label runat="server" id="StatusLabel" text="Upload status: " />
form>

this is the program code.you can control the file size too.... :)


protected void UploadButton_Click(object sender, EventArgs e)
{
    if(FileUploadControl.HasFile)
    {
        try
        {
            if(FileUploadControl.PostedFile.ContentType == "image/jpeg")
            {
                if(FileUploadControl.PostedFile.ContentLength < 102400)
                {
                    string filename = Path.GetFileName(FileUploadControl.FileName);
                    FileUploadControl.SaveAs(Server.MapPath("~/") + filename);
                    StatusLabel.Text = "Upload status: File uploaded!";
                }
                else
                    StatusLabel.Text = "Upload status: The file has to be less than 100 kb!";
            }
            else
                StatusLabel.Text = "Upload status: Only JPEG files are accepted!";
        }
        catch(Exception ex)
        {
            StatusLabel.Text = "Upload status: The file could not be uploaded. The following error occured: " + ex.Message;
        }
