How to display image in WinForms and then delete?

When my form opens it uses the file path that is provided from another form and displays the images, and when I close the form I want it to delete all the images.
But when I close it keeps stating the file is being used, is there a better way of doing it please?
public frmMark(string strImagePath)
{
InitializeComponent();
pbImage1.Image = new Bitmap(strImagePath + "1.jpg");
pbImage2.Image = new Bitmap(strImagePath + "2.jpg");
pbImage3.Image = new Bitmap(strImagePath + "3.jpg");
}
private void frmMark_FormClosing(object sender, FormClosingEventArgs e)
{
File.Delete(deletepath + "1.jpg");
}

Change this:
pbImage1.Image = new Bitmap(strImagePath + "1.jpg");
to this:
pbImage1.ImageLocation = Path.Combine(strImagePath, "1.jpg");
and for the others and your issue should go away because the files will not be locked, so you don't have to worry about unlocking them.

Perhaps create a language extension which clones the original image, load the image then deletes the physical file.
public static class PictureBoxExtensions
{
public static void LoadClone(this PictureBox pictureBox, string fileName)
{
var imageOriginal = Image.FromFile(fileName);
var imageClone = new Bitmap(imageOriginal.Width, imageOriginal.Height);
Graphics gr = Graphics.FromImage(imageClone);
gr.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;
gr.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.NearestNeighbor;
gr.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighSpeed;
gr.DrawImage(imageOriginal, 0, 0, imageOriginal.Width, imageOriginal.Height);
gr.Dispose();
imageOriginal.Dispose();
pictureBox.Image = imageClone; // assign the clone to picture box
File.Delete(fileName); // remove original
}
}
Or if not always needing to remove an image add another parameter,in this case remove where the default is to remove which of course you can set the default to false.
public static class PictureBoxExtensions
{
public static void LoadClone(this PictureBox pictureBox, string fileName, bool remove = true)
{
var imageOriginal = Image.FromFile(fileName);
var imageClone = new Bitmap(imageOriginal.Width, imageOriginal.Height);
Graphics gr = Graphics.FromImage(imageClone);
gr.SmoothingMode = System.Drawing.Drawing2D.SmoothingMode.None;
gr.InterpolationMode = System.Drawing.Drawing2D.InterpolationMode.NearestNeighbor;
gr.PixelOffsetMode = System.Drawing.Drawing2D.PixelOffsetMode.HighSpeed;
gr.DrawImage(imageOriginal, 0, 0, imageOriginal.Width, imageOriginal.Height);
gr.Dispose();
imageOriginal.Dispose();
pictureBox.Image = imageClone; // assign the clone to picture box
if (remove)
{
File.Delete(fileName); // remove original
}
}
}
Usage
public frmMark(string strImagePath)
{
InitializeComponent();
pbImage1.LoadClone(strImagePath + "1.jpg");
pbImage2.LoadClone(strImagePath + "2.jpg");
pbImage2.LoadClone(strImagePath + "3.jpg");
}

image doesn't change - WPF

I'm trying to change an image on runtime but it's not working.
I have a user control that when you click on imagebtn it's opening a new window with a list of images.
the next step is to take the image selected from the list, close the new window, and put the image on the imagebtn.
the user control still opens in the background.
this is my code.
NewWindow:
private string myData;
public ImagesWindow()
{
InitializeComponent();
InitialImageList();
}
private async void InitialImageList()
{
//add try catch
string get = await HttpRequests.GetRequest(URLImages);
allJsonCategory = JsonConvert.DeserializeObject<List<ImageArray>>(get);
Console.WriteLine(get);
ImageBoxList.ItemsSource = images;
foreach (var item in allJsonCategory)
{
images.Add(item);
}
}
private void ImageBoxList_SelectionChanged(object sender, SelectionChangedEventArgs e)
{
selectedImage = (ImageArray)ImageBoxList.SelectedItem;
myData = selectedImage.full_path;
Console.WriteLine("you clicked on: " + selectedImage.name);
ProductsCategory pro = new ProductsCategory();
pro.imagePath = myData;
this.Close();
}
my usercontrol(in mainWindow):
public void setImage(string imagePath)
{
if (!imageURL.Equals(""))
{
Image imageBtn = new Image();
var imgUrl = new Uri(imagePath);
var imageData = new WebClient().DownloadData(imgUrl);
// or you can download it Async won't block your UI
// var imageData = await new WebClient().DownloadDataTaskAsync(imgUrl);
var bitmapImage = new BitmapImage { CacheOption = BitmapCacheOption.OnLoad };
bitmapImage.BeginInit();
bitmapImage.StreamSource = new MemoryStream(imageData);
bitmapImage.EndInit();
imageBtn.Source = bitmapImage;
//this.imageBtn.InvalidateVisual();
}
}
XAML of the image:
where is my mistake?
thank you all :)

how to generate PDF from .aspx page

i want to create PDF, from a currently running .aspx page and i successfully done this. But problem is that when i login through a login page and go for to create a PDF of a report_page(i can access this report_page only when i successfully login) and click on button to generate a PDF of currently running report_page then here PDF is generating of a login page rather than report_page.
And here i have another report_page which need not to login to generate report when i am generating report through this report_page(not need to login) and try to convert it to PDF then it is working correctly means here PDF is generated of report_page.
here i paste my code please check it and give me solution for this:

this.ThumbnailImage = (Bitmap)ThumbnailImage.GetThumbnailImage(Width, Height, null, IntPtr.Zero);
}

The issue is that you are requesting the page-to-be-generated in a separate request which does not include your login cookie/session. It is requesting it as though it was a completely separate browser would.
The only way I can think is that if you have basic authentication turned on in IIS you can change the url to be: http://myThumbnailUser:myThumbnailPassw0rd#www.mydomain.com/path/to/page/to/be/rendered.aspx.
You could try and attach the method that does all the generation to the page unload event to allow you to get the response stream, pump it into the WebBrowser control and thenuse that to generate your PDF.
protected void btn_print_Click(object sender, EventArgs e)
{
try
{
int width = 850;
int height = 550;
this.Page.Unload += delegate {
Thumbnail1 thumbnail = new Thumbnail1(this.Page, 990, 1000, width, height);
Bitmap image = thumbnail.GenerateThumbnail();
image.Save(Server.MapPath("~") + "/Dwnld/Thumbnail.bmp");
imagepath = Server.MapPath("~").ToString() + "\\Dwnld\\" + "Thumbnail.bmp";
imagepath1 = Server.MapPath("~").ToString() + "\\Dwnld\\" + "Thumbnail.pdf";
convetToPdf();
}
}
catch (Exception)
{
throw;
}
}
...
public Thumbnail1(Page page, int BrowserWidth, int BrowserHeight, int ThumbnailWidth, int ThumbnailHeight)
{
this.Page = page;
this.BrowserWidth = BrowserWidth;
this.BrowserHeight = BrowserHeight;
this.Height = ThumbnailHeight;
this.Width = ThumbnailWidth;
}
...
private void GenerateThumbnailInteral()
{
WebBrowser webBrowser = new WebBrowser();
webBrowser.ScrollBarsEnabled = false;
webBrowser.Navigate(this.Url);
webBrowser.DocumentStream = this.Page.Response.GetResponseStream()
webBrowser.ClientSize = new Size(this.BrowserWidth, this.BrowserHeight);
webBrowser.ScrollBarsEnabled = false;
this.ThumbnailImage = new Bitmap(webBrowser.Bounds.Width, webBrowser.Bounds.Height);
webBrowser.BringToFront();
webBrowser.DrawToBitmap(ThumbnailImage, webBrowser.Bounds);
this.ThumbnailImage = (Bitmap)ThumbnailImage.GetThumbnailImage(Width, Height, null, IntPtr.Zero);
}
That also might work..

How do I get an image to save after rotation at runtime?

I am working with WPF and I have an application that the user loads an image file into a RichTextBox and they can rotate the image and print it. I am not sure as to why the image after it has been rotated will not print as it is displayed on the screen. Instead it prints the original. I am new to this so any help would be greatly appreciated!
The following is the code for my application. Code when the retrieve file Button is clicked:
private void retrieve_button_Click(object sender, RoutedEventArgs e)
{
//Retrieve the file or image you are looking for
OpenFileDialog of = new OpenFileDialog();
of.Filter = "Formats|*.jpg;*.png;*.bmp;*.gif;*.ico;*.txt|JPG Image|*.jpg|BMP image|*.bmp|PNG image|*.png|GIF Image|*.gif|Icon|*.ico|Text File|*.txt";
var dialogResult = of.ShowDialog();
if (dialogResult == System.Windows.Forms.DialogResult.OK)
{
try
{
System.Windows.Controls.RichTextBox myRTB = new System.Windows.Controls.RichTextBox();
{
Run myRun = new Run();
System.Windows.Controls.Image MyImage = new System.Windows.Controls.Image();
MyImage.Source = new BitmapImage(new Uri(of.FileName, UriKind.RelativeOrAbsolute));
InlineUIContainer MyUI = new InlineUIContainer();
MyUI.Child = MyImage;
rotateright_button.IsEnabled = true;
print_button.IsEnabled = true;
Paragraph paragraph = new Paragraph();
paragraph.Inlines.Add(myRun);
paragraph.Inlines.Add(MyUI);
FlowDocument document = new FlowDocument(paragraph);
richTextBox.Document = document;
}
}
catch (ArgumentException)
{
System.Windows.Forms.MessageBox.Show("Invalid File");
}
}
}
When the rotate right button is clicked the following code is executed:
RotateTransform cwRotateTransform;
private void rotateright_button_Click(object sender, RoutedEventArgs e)
{
richTextBox.LayoutTransform = cwRotateTransform;
if (cwRotateTransform == null)
{
cwRotateTransform = new RotateTransform();
}
if (cwRotateTransform.Angle == 360)
{
cwRotateTransform.Angle = 0;
}
else
{
cwRotateTransform.Angle += 90;
}
}
After the Image has been loaded and rotated the user can use the following code to print:
private void InvokePrint(object sender, RoutedEventArgs e)
{
System.Windows.Controls.PrintDialog printDialog = new System.Windows.Controls.PrintDialog();
if ((bool)printDialog.ShowDialog().GetValueOrDefault())
{
FlowDocument flowDocument = new FlowDocument();
flowDocument = richTextBox.Document;
flowDocument.ColumnWidth = printDialog.PrintableAreaWidth;
flowDocument.PagePadding = new Thickness(65);
IDocumentPaginatorSource iDocPag = flowDocument;
printDialog.PrintDocument(iDocPag.DocumentPaginator, "Print Document");
}
}

Try this (substitute yourImageControl in the first line, specify which RotateFlipType you want and be sure to reference the System.Drawing dll):
System.Drawing.Bitmap bitmap = BitmapSourceToBitmap((BitmapSource)YourImageControl.Source);
bitmap.RotateFlip(System.Drawing.RotateFlipType.Rotate90FlipNone);
public static System.Drawing.Bitmap BitmapSourceToBitmap(BitmapSource bitmapsource)
{
System.Drawing.Bitmap bitmap;
using (MemoryStream outStream = new MemoryStream())
{
BitmapEncoder enc = new BmpBitmapEncoder();
enc.Frames.Add(BitmapFrame.Create(bitmapsource));
enc.Save(outStream);
bitmap = new System.Drawing.Bitmap(outStream);
}
return bitmap;
}
Another option for conversion...
P.S. You would get a better answer in less time if you posted some code and told us more about what you have tried.

How to load image from isolated storage for secondary tile

I am attempting to populate a secondary tile background with an image saved from the PhotoChooserTask, but for some reason I cannot accomplish this. I have referenced a lot of sites but I have not found the proper implementation. All I do is call PhotoChooserTask, and then on the completed event I save the resulting image to isolated storage to be loaded later. This has worked with a HubTile in my application, but for some reason I cannot append the image to a secondary tile. So far what I have is as follows:
MainPage.xaml.cs
string imageFolder = #"\Shared\ShellContent";
string shareJPEG = "shareImage.jpg";
public MainPage()
{
InitializeComponent();
photoChooserTask = new PhotoChooserTask();
photoChooserTask.Completed += new EventHandler<PhotoResult>(photoChooserTask_Completed);
}
public void changePictureMenuItem_Tap(object sender, System.Windows.Input.GestureEventArgs e)
{
try
{
photoChooserTask.Show();
}
catch (System.InvalidOperationException)
{
MessageBox.Show("An error occurred");
}
}
void photoChooserTask_Completed(object sender, PhotoResult e)
{
if (e.TaskResult == TaskResult.OK)
{
//persist the data in isolated storage
using (IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication())
{
if(!myIsolatedStorage.DirectoryExists(imageFolder))
{
myIsolatedStorage.CreateDirectory(imageFolder);
}
if (myIsolatedStorage.FileExists(shareJPEG))
{
myIsolatedStorage.DeleteFile(shareJPEG);
}
string filePath = System.IO.Path.Combine(imageFolder, shareJPEG);
IsolatedStorageFileStream fileStream = myIsolatedStorage.CreateFile(filePath);
BitmapImage bitmap = new BitmapImage();
bitmap.SetSource(e.ChosenPhoto);
WriteableBitmap wb = new WriteableBitmap(bitmap);
// Encode WriteableBitmap object to a JPEG stream.
Extensions.SaveJpeg(wb, fileStream, 173, 173, 0, 100);
fileStream.Close();
}
}
}
private void CreateLiveTile(TileItem item)
{
//IsolatedStorageFile myIsolatedStorage = IsolatedStorageFile.GetUserStoreForApplication();
var title = item.Title.ToString();
string tileParameter = "Param=" + item.Title.ToString();
ShellTile Tile = CheckIfTileExist(tileParameter); // Check if Tile's title has been used
if (Tile == null)
{
//this is not working?
background = new Uri(#"isostore:/Shared/ShellContent/shareJPEG.png", UriKind.Absolute);
//background = new Uri("isostore:/Shared/ShellContent/shareJPEG.png", UriKind.Absolute);
try
{
var LiveTile = new StandardTileData
{
Title = item.TileName,
BackgroundImage = background, //not working
BackTitle = item.TileName,
BackBackgroundImage = new Uri("/background.png", UriKind.Relative),
BackContent = item.Message,
};
ShellTile.Create(new Uri("/MainPage.xaml?" + tileParameter, UriKind.Relative), LiveTile);
}
}
Ultimately, the secondary tile is created but there is no image for the BackgroundImage. How would I properly call the isolated strorage path to set the BackgroundImage of the secondary tile accordingly? Or is there something else I should be doing or change?

MainPage.xaml.cs
string imageFolder = #"\Shared\ShellContent";
string shareJPEG = "shareImage.jpg";
...
private void CreateLiveTile(TileItem item)
{
var title = item.Title.ToString();
string tileParameter = "Param=" + item.Title.ToString();
ShellTile Tile = CheckIfTileExist(tileParameter); // Check if Tile's title has been used
if (Tile == null)
{
string filePath = System.IO.Path.Combine(imageFolder, shareJPEG);
background = new Uri(#"isostore" + filePath, UriKind.Absolute); //this worked
...
}
}

Are you sure the image is saved successfully and exists? You save it as jpeg but you reference a png file. Try #"\Shared\ShellContent\shareJPEG.png"

first you should put your image at "\Shared\ShellContent" location. you can use .png or .jpg file
string imageFolder = #"\Shared\ShellContent";
string shareJPEG = "shareImage.jpg";
...
private void CreateLiveTile(TileItem item)
{
var title = item.Title.ToString();
string tileParameter = "Param=" + item.Title.ToString();
ShellTile Tile = CheckIfTileExist(tileParameter);
if (Tile == null)
{
string filePath = System.IO.Path.Combine(imageFolder, shareJPEG);
using (var iso = IsolatedStorageFile.GetUserStoreForApplication())
{
if (iso.FileExists(filePath)) // check file exist or not
background = new Uri(#"isostore:" + filePath, UriKind.Absolute);
}
...
}
}
