found this function online, which works great... except I can't figure out how to default it to print in landscape.
private void PrintClick(object sender, RoutedEventArgs e)
{
PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{ dialog.PrintVisual(_PrintCanvas, "My Canvas"); }
}
How does one actually set the default to print my wpf content to landscape mode?
Edit: Fixed variable name, mentioned by #SHIN JaeGuk
private void PrintClick(object sender, RoutedEventArgs e)
{
PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{
//Set PageOrientation to Landscape
dialog.PrintTicket.PageOrientation = PageOrientation.Landscape;
dialog.PrintVisual(_PrintCanvas, "My Canvas");
}
}
Original Answer
This has already been answered:
Setting PageOrientation for the Wpf DocumentViewer PrintDialog
End Original Answer
Edit:
It appears there is a problem with the PrintTicket and printing visuals, check out:
Same question on MSDN
The original poster on the MSDN forum posted on the last post that the work around they used was to basically capture the visual and convert to xps document for printing, this will allow the usage of PrintTicket to set the orientation of the printed document.
private void PrintClick(object sender, RoutedEventArgs e)
{
PrintDialog dialog = new PrintDialog();
if (dialog.ShowDialog() == true)
{
dialog.PrintTicket.PageOrientation=System.Printing.PageOrientation.Landscape;
dialog.PrintVisual(this, "First LandScape");
}
}
You need to add a reference to ReachFramework.dll and System.Printing.dll each.

i have been looking for a while now, i have found a solution in csharp , but i couldn't translate it (implement it in my vb.net app).
My only aim is that when the user clicks a link no popups appear.
thank you for your help.
My vb.net coding skill is beginner level, c sharp no knowledge.
the working solution in c sharp:
using CefSharp;
using CefSharp.WinForms;
namespace popup_cefsharp
{
public partial class frm_main : Form
{
public frm_main()
{
InitializeComponent();
}
//variable
ChromiumWebBrowser chrome, chrome_popup;
private void initialize_browser()
{
try
{
CefSettings settings = new CefSettings();
Cef.Initialize(settings);
//main browser
chrome = new ChromiumWebBrowser(this.txt_url.Text.Trim());
LifespanHandler life = new LifespanHandler();
chrome.LifeSpanHandler = life;
life.popup_request += life_popup_request;
this.pan_container.Controls.Add(chrome);
chrome.Dock = DockStyle.Fill;
//second browser (popup browser)
chrome_popup = new ChromiumWebBrowser("");
this.pan_container_popup.Controls.Add(chrome_popup);
chrome_popup.Dock = DockStyle.Fill;
}
catch (Exception ex)
{
MessageBox.Show("Error in initializing the browser. Error: " + ex.Message);
}
}
private void carregar_popup_new_browser(string url)
{
//open pop up in second browser
chrome_popup.Load(url);
}
private void frm_main_FormClosing(object sender, FormClosingEventArgs e)
{
//close o object cef
Cef.Shutdown();
Application.Exit();
}
private void frm_main_Load(object sender, EventArgs e)
{
//initialize the browser
this.initialize_browser();
}
private void life_popup_request(string obj)
{
//function for open pop up in a new browser
this.carregar_popup_new_browser(obj);
}
}
}
link original post: https://www.codeproject.com/Articles/1194609/Capturing-a-pop-up-window-using-LifeSpanHandler-an
finally found the solution , if anyone is interested
here is the link, you will need to install the cefsharp nuggets packages, add lifespanhandler as a new class, the file is in the link, then copy the method to call the function from the mainform...
cheers...

I'm having an issue with duplicated content from redirected output.
In my forms I have two buttons: Run and Clear.
public partial class BatchRun : Form
{
Process process = new Process();
public BatchRun()
{
InitializeComponent();
}
private void RunBTN_Click(object sender, EventArgs e)
{
//initiate the process
this.process.StartInfo.FileName = sMasterBATname;
this.process.StartInfo.UseShellExecute = false;
this.process.StartInfo.CreateNoWindow = true;
this.process.StartInfo.RedirectStandardOutput = true;
this.process.OutputDataReceived += new DataReceivedEventHandler(StandardOutputHandler);
this.process.StartInfo.RedirectStandardInput = true;
this.process.Start();
this.process.BeginOutputReadLine();
}
public void StandardOutputHandler(object sender, DataReceivedEventArgs outLine)
{
BeginInvoke(new MethodInvoker(() =>
{
Label TestLBL = new Label();
TestLBL.Text = text.TrimStart();
TestLBL.AutoSize = true;
TestLBL.Location = new Point(10, CMDpanel.AutoScrollPosition.Y + CMDpanel.Controls.Count * 20);
CMDpanel.Controls.Add(TestLBL);
CMDpanel.AutoScrollPosition = new Point(10, CMDpanel.Controls.Count * 20);
}));
}
private void ClearBTN_Click(object sender, EventArgs e)
{
CMDpanel.Controls.Clear();
this.process.CancelOutputRead();
this.process.Close();
this.process.Refresh();
}
}
This works great if I want to run process only once i.e. close the forms once process has completed.
However, I need to allow user to rerun the same process or run a new one hence I have added a clear button the clear various controls etc.
The problem I'm having is that after clicking clear button, I want to click run button again without closing which should then run the sMAsterBAT file(CMD).
StandardOutputHandler seems to be including content of the previous run as well as the new one resulting in duplicated labels in my CMDpanel.
Is this stored in some kind of buffer? If so, How do i clear it to allow me a rerun?
Could someone explain why this is happening and how to resolve it please.
Spoke to someone at work who fixed it for me. So easy lol
private void ClearBTN_Click(object sender, EventArgs e)
{
CMDpanel.Controls.Clear();
this.process.CancelOutputRead();
this.process.Close();
this.process.Refresh();
this.process = new Process(); // this line resolved my issue!!
}
}
I'm trying to drag an image file from explorer into my wpf image control. My current code is
private void Image_Drop(object sender, DragEventArgs e)
{
string fpath = (string)e.Data.GetData(DataFormats.StringFormat);
BitmapImage tmpImage = new BitmapImage((new Uri(fpath)));
testImg.Source = tmpImage;
}
Which is currently giving me NullReferenceException error when I drop the file on the control.
Update:
Using Patrick's suggestion, by changing the code to this
private void Image_Drop(object sender, DragEventArgs e)
{
object data = e.Data.GetData(DataFormats.FileDrop);
foreach (string str in (string[])data)
{
BitmapImage tmpImage = new BitmapImage((new Uri(str)));
testImg.Source = tmpImage;
}
}
The image correctly update the source. Will probably need to add code for handling multiple images selection drop.
You should use the DataFormats.FileDrop. It will give a list of file names in the GetData. This is a working example from my own app:
object data = e.Data.GetData(DataFormats.FileDrop);
if (data is string[])
{
string[] files = (string[])data;
}
You are trying to get a file as a string, so I imagine it's your e.Data.GetData(DataFormats.StringFormat) line that is throwing. If you're dropping a bitmap onto your control then you can treat it as such. Try this.
private void Image_Drop(object sender, DragEventArgs e)
{
BitmapImage tmpImage = e.Data.GetData(DataFormats.Bitmap);
testImg.Source = tmpImage;
}
Although I recommend you put in code to ensure you are checking the type of what has been dragged onto your control before assuming it is a bitmap.
I want to read a text file from the Internet and I want while reading the file a picturebox, that is a gif animation, show and after the reading is finished picturebox hide.
I use background worker. I have a lable that shows the state, but when I click BtnCheck Button bg doesn't work and the lable doesn't change.
My code:
private void Form1_Load(object sender, EventArgs e)
{
backgroundWorker1.WorkerReportsProgress = true;
backgroundWorker1.WorkerSupportsCancellation = true;
}
private void BtnCheck_Click(object sender, EventArgs e)
{
PbLoading.Visible = true;
if (backgroundWorker1.IsBusy != true)
{
// Start the asynchronous operation.
backgroundWorker1.RunWorkerAsync();
}
}
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
LbleState.Text = "Reading txt File...";
webClient1 = new WebClient();
if (CheckForInternetConnection())
{
try
{
Stream stream = webClient1.OpenRead(TxtWebAdrss);
StreamReader reader = new StreamReader(stream);
String content = reader.ReadToEnd();
reader.Close();
LbleState.Text = "Reading Finished .";
}
catch
{
LbleState.Text = "Error reading";
}
}
else LbleState.Text = "Internet not connected!";
}
You may just need to do a bit more research into this class. You should perform UI changes on the UI thread.
There are three event handlers that you can use and these are,
backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
backgroundWorker1_ProgressChanged(object sender, ProgressChangedEventArgs e)
backgroundWorker1_RunWorkerCompleted(object sender, RunWorkerCompletedEventArgs e)

I am working on a Windows 8 metro app and having multiple SettingsFlyout items which get added by below mentioned code
SettingsCommand cmd1 = new SettingsCommand("sample", "Color Settings", (x) =>
{
// create a new instance of the flyout
SettingsFlyout settings = new SettingsFlyout();
// set the desired width. If you leave this out, you will get Narrow (346px)
// optionally change header and content background colors away from defaults (recommended)
// if using Callisto's AppManifestHelper you can grab the element from some member var you held it in
// settings.HeaderBrush = new SolidColorBrush(App.VisualElements.BackgroundColor);
settings.HeaderBrush = new SolidColorBrush(Colors.Black);
settings.HeaderText = string.Format("Color Settings", App.VisualElements.DisplayName);
settings.Background = new SolidColorBrush(_background);
settings.Margin = new Thickness(0);
// provide some logo (preferrably the smallogo the app uses)
BitmapImage bmp = new BitmapImage(App.VisualElements.SmallLogoUri);
settings.SmallLogoImageSource = bmp;
// set the content for the flyout
settings.Content = new ColorSettings();
settings.HorizontalAlignment = Windows.UI.Xaml.HorizontalAlignment.Stretch;
// open it
settings.IsOpen = true;
// this is only for the test app and not needed
// you would not use this code in your real app
// ObjectTracker.Track(settings);
});
Currently using (SettingsPane.Show()) i can be able to show the added flyout items list but I want to programmatically open any setting Flyout item instead of opening a flyout list.
Create a new class
public class SettingsFlyout
{
private const int _width = 346;
private Popup _popup;
/// <summary>
/// Show the Flyout with the UserControl as content
/// </summary>
/// <param name="control"></param>
public void ShowFlyout(UserControl control)
{
_popup = new Popup();
_popup.Closed += OnPopupClosed;
Window.Current.Activated += OnWindowActivated;
_popup.IsLightDismissEnabled = true;
_popup.Width = _width;
_popup.Height = Window.Current.Bounds.Height;
control.Width = _width;
control.Height = Window.Current.Bounds.Height;
_popup.Child = control;
_popup.SetValue(Canvas.LeftProperty, Window.Current.Bounds.Width - _width);
_popup.SetValue(Canvas.TopProperty, 0);
_popup.IsOpen = true;
}
private void OnWindowActivated(object sender, Windows.UI.Core.WindowActivatedEventArgs e)
{
if (e.WindowActivationState == Windows.UI.Core.CoreWindowActivationState.Deactivated)
{
_popup.IsOpen = false;
}
}
void OnPopupClosed(object sender, object e)
{
Window.Current.Activated -= OnWindowActivated;
}
}
In a XAML page take a button and then write the button click event.
private void Button_Click_1(object sender, RoutedEventArgs e)
{
SettingsFlyout flyout = new SettingsFlyout();
flyout.ShowFlyout(new FlyoutContentUserControl());
}
Please note one thing FlyoutContentUserControl is the user control which you would like to show.
Credits goes to Q42.WinRT
The code you posted registers a SettingsCommands to the system settings pane. When your command is invoked from the system settings pane, you new up a SettingsFlyout instance and set IsOpen=True on it.
You just need to refactor this code to a separate method (e.g. ShowColorSettingsFlyout()), and also call that method from your Button.Click event handler. You can create a new Callisto SettingsFlyout and set IsOpen=True on it anywhere.
In App.xaml.cs add the following to register your SettingsFlyout e.g. CustomSetting ...
protected override void OnWindowCreated(WindowCreatedEventArgs args)
{
SettingsPane.GetForCurrentView().CommandsRequested += OnCommandsRequested;
}
private void OnCommandsRequested(SettingsPane sender, SettingsPaneCommandsRequestedEventArgs args)
{
args.Request.ApplicationCommands.Add(new SettingsCommand(
"Custom Setting", "Custom Setting", (handler) => ShowCustomSettingFlyout()));
}
public void ShowCustomSettingFlyout()
{
CustomSetting CustomSettingFlyout = new CustomSetting();
CustomSettingFlyout.Show();
}
Then anywhere in your code you want to programmatically open the CustomSetting flyout, call ShowCustomSettingFlyout, e.g. in the event handler for a button click...
void Button_Click_1(object sender, RoutedEventArgs e)
{
ShowCustomSettingFlyout()
}
