[RESOLVED] Error in calling a class

Hi, i have a class, with 2 functions in it. I am calling them like normal, but it seems to error.

My class:

c# Code:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Drawing;
 
namespace WebBrowser
{
    class Mypicssave
    {
        public static void Mypictures(Bitmap thumbnail)
        {
            String SaveName = DateTime.Now.ToShortDateString().Replace("/", "-") + ".png";
            thumbnail.Save(Environment.SpecialFolder.MyPictures + @"\" + SaveName, System.Drawing.Imaging.ImageFormat.Png);
        }
        public static void Specicifed(Bitmap thumbnail)
        {
            String SaveName = DateTime.Now.ToShortDateString().Replace("/", "-") + ".png";
            thumbnail.Save(Properties.Settings.Default.specifiedfolder + @"\" + SaveName, System.Drawing.Imaging.ImageFormat.Png);
        }
 
    }
 
}

And my error:

Any chance someone could help me?

Hey,

Ok, that's better.

So you have defined a method as:

Code:

---

public static void Mypictures(Bitmap thumbnail)

---

It is expecting a parameter of type Bitmap when it is called, but you are not giving it one. You would need to call it like:

Code:

---

Mypicsave.MyPictures(myBitmap);

---

Where myBitmap is an instance of a Bitmap class that you want to work with.

Gary

Okay, so if i put mybitmap it should work? Or would i have to put thumbnail or something?

Hey,

mybitmap was just an example variable name, to indicate how it should be called. I was assuming that elsewhere in your code you already have a variable of type Bitmap that you are using. Is this not the case?

Gary

Well i have the thumbnail generate image, which i want to be saved and when i replace myBitmap with thumbnail it errors too, so im not sure...could you look through the whole source link and see what is what..Please?

Hey,

What is the error that you are getting now?

Gary

Oh, I see what it is...

Code:

---

private void screenshotToolStripMenuItem_Click(object sender, EventArgs e)
        {
            if (Properties.Settings.Default.prompt == true)
            {
                Bitmap thumbnail = GenerateScreenshot(webBrowser1.Url.ToString());
                SaveFileDialog saveDialog = new SaveFileDialog();
                saveDialog.Filter = "JPeg Image|*.jpg";
                saveDialog.Title = "Save Image as";
                saveDialog.ShowDialog();
                if (saveDialog.FileName != string.Empty)
                    thumbnail.Save(saveDialog.FileName, ImageFormat.Jpeg);
 
                thumbnail.Dispose();
            }
            else if (Properties.Settings.Default.Mypics == true)
                {
                    Mypicssave.Mypictures();
                }
 
            else if (Properties.Settings.Default.Specified == true)
                {
                    Mypicssave.Specicifed();
                }
                    }

---

thumbnail is created within the first if statement, as a result, it does not exist when/if you go into the else if statements. You are likely getting a compile error saying that thumbnail is not declared anywhere. Try the following:

Code:

---

private void screenshotToolStripMenuItem_Click(object sender, EventArgs e)
        {
            Bitmap thumbnail = GenerateScreenshot(webBrowser1.Url.ToString());

            if (Properties.Settings.Default.prompt == true)
            {
                SaveFileDialog saveDialog = new SaveFileDialog();
                saveDialog.Filter = "JPeg Image|*.jpg";
                saveDialog.Title = "Save Image as";
                saveDialog.ShowDialog();
                if (saveDialog.FileName != string.Empty)
                    thumbnail.Save(saveDialog.FileName, ImageFormat.Jpeg);
 
                thumbnail.Dispose();
            }
            else if (Properties.Settings.Default.Mypics == true)
                {
                    Mypicssave.Mypictures(thumbnail);
                }
 
            else if (Properties.Settings.Default.Specified == true)
                {
                    Mypicssave.Specicifed(thumbnail);
                }
                    }
