Displaying images on a form using code

Displaying images on a form using code

• Joe Mirwaisi

  Thanks for the help, I was thinking i had to create an array of pictureboxes and add eachone to the array through the loop.
  I do have one question about your solution, doesn't it create multiple 'pb' objects and all with the same name
  
  I also have another code question, I couldn't find out how to do this anywhere online, but how do you find the number of filenames that were selected when you allow a dialog box to have multiple selections
  
  -You have been very helpful
  -Thanks

  Here is the resulting code you helped me with, thanks. I also posted a resulting picture of the code on my blog: http://learningcode.blogspot.com/ 
  
  Also, is there an easier way of retrieving the number of image files besides keeping a tally in the foreach loop
  
  Thanks
  
  private void btnAddImages_Click(object sender, EventArgs e)

  {

  int selectedImage = 0;

  int imageLocationX = 13;

  int imageLocationY = 132;

  PageGenerator ActivePage = new PageGenerator();

  if (dlgBoxSelectImage.ShowDialog()==DialogResult.OK)

  {

  foreach (string newImage in dlgBoxSelectImage.FileNames)

  {

  //Creating a new image and displaying it

  PictureBox pb = new PictureBox();

  pb.Image = Image.FromFile(newImage);

  this.Controls.Add(pb);

  //Changing the picture properties

  pb.Location = new Point(imageLocationX, imageLocationY);

  pb.SizeMode = PictureBoxSizeMode.Zoom;

  pb.Size = new Size(88, 88);

  //View number of items selected

  Console.WriteLine(selectedImage);

  //Setting Properties for next image

  ++selectedImage;

  if (selectedImage%4==0)

  {

  imageLocationY += 90;

  imageLocationX = 13;

  }

  else

  {

  imageLocationX += 90;

  }

  }

  }

  }

  Hi,
  
  
  Here's a code that Displays a picture in the picturebox given a filename....
  
  pictureBox1.Image = Drawing.Image.FromFile("C:\\myPic.jpg");
  
  
  It's your decision if you try to loop, But I suggest just display it in a listbox... let the user choose on what he wants to view...

  Hi,
  
  
  Here's code for Location and size:
  
  
  pictureBox1.Location = Drawing.Point(100,100);
  pictureBox1.Size = Drawing.Size(100,100);
  
  
  
  
  cheers,

  I was looking if someone can give me some help with my code. I need to know what the best way would be to have a dialog box that returns an array of image filenames and use that array to create a new picture box for each image that was selected and display it on the form Should i use a for loop or a foreach loop I think I just need help figuring out the best way to create a new picture box for each image. What I plan to do after the images are displayed on the form is let the user select which images he would like removed. Once all the he wants are selected and displayed on the form I will then copy the images to a new directory. Here is what I have so far... private void btnAddImages_Click(object sender, EventArgs e) { if (dlgBoxSelectImage.ShowDialog()==DialogResult.OK) {    foreach (string images in dlgBoxSelectImage.FileNames)    {          //Not Sure what should go here...    } } }

  
  Mike,
  
     What you want to do is create a new PictureBox, add it to the form, and then set the image.  So, you can do this in your loop:
  
  

  PictureBox pb = new PictureBox();pb.Image = Image.FromFile("filename");this.Controls.Add(pb);

  
  
     You will also want to add code that will set the position of the imageboxes, so that they are aligned nicely.
  
     Hope this helps.
