hi,

Subject: ImageResize in else statement.

i am using asp.net with c# using dotnetnuke.

when i upload a image it will check the valid image width and height size.

if it is valid saved. if it is invalid got to resize.

for example:

This is my code to check the valid image width and height size.
=======
protected void cmdUpdate_Click(System.Object sender, System.EventArgs e)
 {

using (System.Drawing.Bitmap objmap = new System.Drawing.Bitmap(FileUpload1.PostedFile.InputStream, false))
                {
            int one, two;
                    string path2 = "";
                    one = Convert.ToInt32(fixedWide);
                    two = Convert.ToInt32(fixedHgt);
                    if (objmap.Width == one && objmap.Height == two)
                    {
                        path1 = FileUpload1.PostedFile.FileName.ToString();
                        path2 = path1.Substring(path1.LastIndexOf("\\") + 1);

                        string getimagepath = Server.MapPath(@"~\ImageFolders\");
                        getimagepath = getimagepath  + Convert.ToString(ModuleId) + "_img_" + path2;
                        FileUpload1.SaveAs(getimagepath);
                        lblMsg.Text = "filesaved";
                    }
                    else
                    {
                        lblMsg.Text = "Please give valid image size...";
                    }
                }
}
=====
This code is run good.my question is: how to call the resize function in else statement.
i don't know how to do image resize function. so, please give some idea and related reference source.

and

i just cut and paste this code in my else part statement: but i don't know this is correct or not?

Please verify where can i made mistake?

This is my full code for imageupload:
