Sending wrong paper size to printer

We have started a project for printing, however we are completely stuck when it comes to telling the printer what paper size is selected.
Everytime we select the paper size and hit print, the printer preview is showing A4 everytime and not our selected size although if we open the print preferences the correct size is selected.

I expect if we select A5, it tells the print driver to print A5,
If we select a custom "user defined" paper size, it tells the printer which size is selected. And not fixing this at A4 everytime
We cant seem to set the paper size outside the print dialog.

I believe; following this and this MSDN article; you are going to want to do something along the lines of:
System.Drawing.Printing.PaperSize paperSize = new System.Drawing.Printing.PaperSize("custom", width, height);
PrintDocument printDoc = new PrintDocument();
printDoc.DefaultPageSettings.PaperSize = paperSize;

I have walk through your code,
I think some event raise by front end (XAML) on specific use cases that is the overriding the actual value in "Properties.Settings.Default."
It would be better to resolve if you provide a XAML code for this issue.
I can look into it and will give you better solution.

add multiple images from openfiledilog to imagelist and display them in the listview

hello friends i am new to c# i am in a project and i want help
i want to add multiple images from openfiledilog to imagelist and display them in the listview.
its adding the images but showing the same picture
and here goes my code.. please help me
int b = 0;![enter image description here][1]
private void Form1_Load(object sender, EventArgs e)
{
var ofd = new OpenFileDialog();
ofd.Multiselect = true;
ofd.ShowDialog();
for (int z = 1; z <= ofd.FileNames.Length ; z++)
{
Image img = Image.FromFile(ofd.FileName);
string a = b.ToString();
imageList1.Images.Add(a, img);
var listViewItem = listView1.Items.Add("1");
listViewItem.ImageKey = a;
b++;
}
}

You need to iterate over the FileNames array instead of using the FileName property.
int b = 0;
private void Form1_Load(object sender, EventArgs e)
{
var ofd = new OpenFileDialog();
ofd.Multiselect = true;
ofd.ShowDialog();
for (int z = 0; z < ofd.FileNames.Length ; z++)
{
Image img = Image.FromFile(ofd.FileNames[z]);
string a = b.ToString();
imageList1.Images.Add(a, img);
var listViewItem = listView1.Items.Add("1");
listViewItem.ImageKey = a;
b++;
}
}
or
int b = 0;
private void Form1_Load(object sender, EventArgs e)
{
var ofd = new OpenFileDialog();
ofd.Multiselect = true;
ofd.ShowDialog();
foreach (string fileName in ofd.FileNames)
{
Image img = Image.FromFile(fileName);
string a = b.ToString();
imageList1.Images.Add(a, img);
var listViewItem = listView1.Items.Add("1");
listViewItem.ImageKey = a;
b++;
}
}

display image from listview to picturebox

I want to display image from list to picturebox.
My image is displaying in the picturebox but the problem is it shows the size the of the image in the picturebox that is defined in the list. Can anyone tell me how to enlarge my image size?
here is my piece of code:
private void listView_SelectedIndexChanged(object sender, EventArgs e)
{
foreach (ListViewItem itm in listView.SelectedItems)
{
int imgIndex = itm.ImageIndex;
if (imgIndex >= 0 && imgIndex < this.documents.Images.Count)
{
// this.documents.Images[imgIndex].Width = 417;
pictureBox.Image = this.documents.Images[imgIndex];
}
}
}
and this is how I am getting images from the database:
ImageList documents = new ImageList();
if (documents.Images.Count < 1)
{
MessageBox.Show("No Documents Found.");
}
else
{
// pictureBox.Image = documents.Images[1];
this.listView.View = View.LargeIcon;
documents.ImageSize = new Size(256, 256);
listView.LargeImageList = documents;
listView.Items.Clear();
for (int j = 0; j < documents.Images.Count; j++)
{
ListViewItem item = new ListViewItem();
item.ImageIndex = j;
this.listView.Items.Add(item);
}
}

PictureBox has SizeMode property that is used for manipulating image size:
pictureBox.SizeMode = PictureBoxSizeMode.StretchImage;
More about that on MSDN

-Create a new imagelist (imagelist1)**
-Add images to your imagelist
-Create a new listview (listview1)
-Create a picturebox (picturebox1)
-Create a new button (button1)
-Create another button (button2)**
-Import images from imagelist1 to listview1
private void button1_Click(object sender, EventArgs e)
{
listView1.Scrollable = true;
listView1.View = View.LargeIcon;
imageList1.ImageSize = new Size(100, 100);
listView1.LargeImageList = imagelist1;
for (int i = 0; i < imagelist1.Images.Count; ++i)
{
string s = imagelist1.Images.Keys[i].ToString();
ListViewItem lstItem = new ListViewItem();
lstItem.ImageIndex = i;
lstItem.Text = s;
listView1.Items.Add(lstItem);
}
}
- Set the selected image into your picture box from listview
private void button2_Click(object sender, EventArgs e)
{
if (this != null && listView1.SelectedItems.Count > 0)
{
ListViewItem lvi = listView1.SelectedItems[0];
string imagekeyname = lvi.Text;
if (this.pictureBox1.Image != null)
{
this.pictureBox1.Image.Dispose();
this.pictureBox1.Image = null;
}
//set the selected image into your picturebox
this.pictureBox1.Image = imagelist1.Images[imagekeyname];
}
}

Clear PictureBox - c#

I'd like to modify this PictureBox Array Project.
i want to put a reset button than will clear all the PictureBox Array it created
more likely the form will be empty again as like from the beginning.
this is some of it's code;
// Function to add PictureBox Controls
private void AddControls(int cNumber)
{
imgArray = new System.Windows.Forms.PictureBox[cNumber]; // assign number array
for (int i = 0; i < cNumber; i++)
{
imgArray[i] = new System.Windows.Forms.PictureBox(); // Initialize one variable
}
// When call this function you determine number of controls
}
private void ImagesInFolder()
{
FileInfo FInfo;
// Fill the array (imgName) with all images in any folder
imgName = Directory.GetFiles(Application.StartupPath + #"\Images");
// How many Picture files in this folder
NumOfFiles = imgName.Length;
imgExtension = new string[NumOfFiles];
for (int i = 0; i < NumOfFiles; i++)
{
FInfo = new FileInfo(imgName[i]);
imgExtension[i] = FInfo.Extension; // We need to know the Extension
//
}
}
private void ShowFolderImages()
{
int Xpos = 8;
int Ypos = 8;
Image img;
Image.GetThumbnailImageAbort myCallback =
new Image.GetThumbnailImageAbort(ThumbnailCallback);
MyProgress.Visible = true;
MyProgress.Minimum = 1;
MyProgress.Maximum = NumOfFiles;
MyProgress.Value = 1;
MyProgress.Step = 1;
string[] Ext = new string [] {".GIF", ".JPG", ".BMP", ".PNG"};
AddControls(NumOfFiles);
for (int i = 0; i < NumOfFiles; i++)
{
switch (imgExtension[i].ToUpper())
{
case ".JPG":
case ".BMP":
case ".GIF":
case ".PNG":
img = Image.FromFile(imgName[i]); // or img = new Bitmap(imgName[i]);
imgArray[i].Image = img.GetThumbnailImage(64, 64, myCallback, IntPtr.Zero);
img = null;
if (Xpos > 432) // six images in a line
{
Xpos = 8; // leave eight pixels at Left
Ypos = Ypos + 72; // height of image + 8
}
imgArray[i].Left = Xpos;
imgArray[i].Top = Ypos;
imgArray[i].Width = 64;
imgArray[i].Height = 64;
imgArray[i].Visible = true;
// Fill the (Tag) with name and full path of image
imgArray[i].Tag = imgName[i];
imgArray[i].Click += new System.EventHandler(ClickImage);
this.BackPanel.Controls.Add(imgArray[i]);
Xpos = Xpos + 72; // width of image + 8
Application.DoEvents();
MyProgress.PerformStep();
break;
}
}
MyProgress.Visible = false;
}
private bool ThumbnailCallback()
{
return false;
}
private void btnLoad_Click(object sender, System.EventArgs e)
{
ImagesInFolder(); // Load images
ShowFolderImages(); // Show images on PictureBox array
this.Text = "Click wanted image";
}
how can i do that?
sorry i don't have any code for the reset button yet.
i don't know what to do, i am new to c#.

You can just set the image to null:
private void Clear()
{
foreach (var pictureBox in imgArray)
{
pictureBox.Image = null;
pictureBox.Invalidate();
}
}

I will follow this steps to be sure everything will be fred :
private void btnReset_Click(object sender, System.EventArgs e)
{
for(int x = this.BackPanel.Controls.Count - 1; x >= 0; x--)
{
if(this.BackPanel.Controls[x].GetType() == typeof(PictureBox))
this.BackPanel.Controls.Remove(x);
}
for(int x = 0; x < imgArray.Length; x++)
{
imgArray[x].Image = null;
imgArray[x] = null;
}
}

Assuming there are no other child controls in this.Backpanel (the container control that is actually displaying your images), this will probably work:
private void ClearImages() {
this.BackPanel.Controls.Clear();
imgArray = null;
}
Good Luck!

If you are drawing on a pictureBox and you want to clear it:
Graphics g = Graphics.FromImage(this.pictureBox1.Image);
g.Clear(this.pictureBox1.BackColor);
After that you can draw again on the control.
I hope this can help to someone.

Images not changing on new search. C# (asp.net project)

This uses bing's web service. I have a single image button and an array of image buttons. The single changes each time it is clicked to the next image in the array. The problem is if I click it and do a new search the array of image buttons does not change.
CODE:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using bing_search.net.bing.api;
using System.Collections;
namespace bing_search
{
public partial class _Default : System.Web.UI.Page
{
static ArrayList images = new ArrayList();
static Image[] imagearry;
static ImageButton[] imgButtnsArray;
static int counter = 0;
int fooBarCount = 0;
int firstLoad = 0;
protected void Page_Load(object sender, EventArgs e)
{
}
protected void DoItButton_Click(object sender, EventArgs e)
{
images.Clear();
imagearry = null;
imgButtnsArray = null;
BingService bs = new BingService();
net.bing.api.SearchRequest req = new SearchRequest();
req.AppId = "0B15AB60D625A10059A4A04B68615C5B0D904CA9";
req.Query = SearchBox.Text;
req.Sources = new SourceType[] { SourceType.Image};
req.Market = "en-us";
req.Adult = AdultOption.Off;
req.Image = new ImageRequest();
req.Image.CountSpecified = true;
req.Image.Count = 50;
SearchResponse resp = bs.Search(req);
foreach (ImageResult result in resp.Image.Results)
{
Image im = new Image();
im.ImageUrl = result.MediaUrl;
im.Width = 200;
im.Height = 200;
images.Add(im);
//this.Controls.Add(im);
}
// Image lol = (Image)images[0];
int size = images.Count;
imagearry = new Image[size];
Type typ = typeof(Image);
imagearry = (Image [])images.ToArray(typ);
ImageButton1.ImageUrl = imagearry[0].ImageUrl;
int blaCount = 0;
ArrayList imgButtns = new ArrayList();
foreach (Image ii in images)
{
ImageButton imgb = new ImageButton();
imgb.Width = 200;
imgb.Height = 200;
imgButtns.Add(imgb);
}
size = imgButtns.Count;
imgButtnsArray = (ImageButton[])imgButtns.ToArray(typeof(ImageButton));
foreach (ImageButton iii in imgButtnsArray)
{
imgButtnsArray[fooBarCount].ImageUrl = imagearry[fooBarCount].ImageUrl;
Panel1.Controls.Add(iii);
fooBarCount++;
}
fooBarCount = 0;
counter = 0;
}
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
counter++;
heightLable.Text = "clicked";
Image tempImage = (Image)imagearry[counter];
ImageButton1.ImageUrl = tempImage.ImageUrl;
foreach (ImageButton iii in imgButtnsArray)
{
imgButtnsArray[fooBarCount].ImageUrl = imagearry[fooBarCount].ImageUrl;
Panel1.Controls.Add(iii);
fooBarCount++;
}
fooBarCount = 0;
counter = 0;
}
}
}

You reset both counters on every click, so its always starts from the same image.
fooBarCount = 0;
counter = 0;
also they are not static, so they reset to 0 anyway on every page load, and show the same image and not change.
If from the other hand the cache is the problem, because I can not know whats the image file name, and maybe this is the issue here, then try something like.
imgButtnsArray[fooBarCount].ImageUrl =
imagearry[fooBarCount].ImageUrl +
"?rnd=" + RandomNumber.ToString();

I changed ImageButton1_Click to this and now it works. thanks for the quick responses. Back to playing with .net
protected void ImageButton1_Click(object sender, ImageClickEventArgs e)
{
counter++;
heightLable.Text = "clicked";
Image tempImage = (Image)imagearry[counter];
ImageButton1.ImageUrl = tempImage.ImageUrl;
//Random RandomNumber = new Random(10000);
foreach (ImageButton iii in imgButtnsArray)
{
Panel1.Controls.Add((Image)imagearry[fooBarCount]);
fooBarCount++;
}
fooBarCount = 0;
counter = 0;
}
