How to set font size in DateTimePicker - c#

I want to increase font size in DateTimePicker in Window Form C#. I want to set minimum 14 to 16 font size in DateTime picker.
I have tried below code but it's not working.
dateTimePicker1.CalendarFont = new Font("Courier New", 8.25F, FontStyle.Italic, GraphicsUnit.Point, ((Byte)(0)));

If you wish to retain visual styles for the other controls in your application, but disable for the date picker's drop down only, you can use the following code:
public class MyDateTimePicker : DateTimePicker
{
[DllImport("uxtheme.dll", ExactSpelling = true, CharSet = CharSet.Unicode)]
static extern Int32 SetWindowTheme(IntPtr hWnd, String textSubAppName, String textSubIdList);
[DllImport("user32.dll", CharSet = CharSet.Auto)]
static extern IntPtr SendMessage(IntPtr hWnd, UInt32 Msg, IntPtr wParam, IntPtr lParam);
[DllImport("user32.dll", SetLastError = true)]
static extern IntPtr GetParent(IntPtr hWnd);
[DllImport("user32.dll", SetLastError = true)]
static extern bool MoveWindow(IntPtr hWnd, int X, int Y, int nWidth, int nHeight, bool bRepaint);
protected override void OnDropDown(EventArgs eventargs)
{
if (Application.RenderWithVisualStyles)
{
const int DTM_GETMONTHCAL = 0x1008;
//Get handle of calendar control - disable theming
IntPtr hCalendar = SendMessage(this.Handle, DTM_GETMONTHCAL, IntPtr.Zero, IntPtr.Zero);
if (hCalendar != IntPtr.Zero)
{
SetWindowTheme(hCalendar, "", "");
//Get handle of parent popup - resize appropriately
IntPtr hParent = GetParent(hCalendar);
if (hParent != IntPtr.Zero)
{
//The size you specify here will depend on the CalendarFont size chosen
MoveWindow(hParent, 0, 0, 400, 300, true);
}
}
}
base.OnDropDown(eventargs);
}
}

In main program delete / comment line Application.EnableVisualStyles();
and add new line of code after yours:
dateTimePicker1.Font = new Font("Courier New", 8.25F, FontStyle.Italic, GraphicsUnit.Point, ((Byte)(0)));

In iOS u have to make a renderer:
private void SetFont(CustomPicker view)
{
UIFont uiFont;
Control.Font = UIFont.SystemFontOfSize(11f); //the size which u want
}
In android you have to set the font for the renderer:
private void SetFont(CustomDatePicker view)
{
if (view.Font != Font.Default)
{
Control.TextSize = view.Font.ToScaledPixel();
Typeface font = Typeface.CreateFromAsset(Forms.Context.Assets,"Roboto-Bold.ttf");
Control.Typeface = font;
Control.Typeface = view.Font.ToTypeface();
}
}

Autoresize called process within a panel C#

I have the following code that opens notepad within a tabControl panel, this works when I start the form maximized.
this.WindowState = FormWindowState.Maximized
Tab Opening:
TabPage tp = new TabPage("notepad");
Panel tb = new Panel();
tb.Dock = DockStyle.Fill;
tp.Controls.Add(tb);
myTab.TabPages.Add(tp);
The problem is when I launch the form not maximized, opens Notepad then resize the form, the following happens (see picture link) --- notepad doesn't stretch out.
After Opening Notepad within Panel the form is maximized
Any suggestions? Thanks!

return ShowWindowAsync(_Process.MainWindowHandle, nCmdShow);
}
After few trials, I was able to resize it automatically.
On my loadProcess method, I have stored the process in a hashtable for reference later.
Process p = Process.Start("Notepad");
p.WaitForInputIdle();
sessions.Add(tabName, p);
on tabControl1_Selecting event:
String name = myProcess.SelectedTab.Name;
Process pHandle = (Process) sessions[name];
SetForegroundWindow(pHandle.MainWindowHandle);
SetFocus(pHandle.MainWindowHandle);
MoveWindow(pHandle.MainWindowHandle, 0, 0, this.Width, this.Height, true);
I've added a Form1_Resize event so it will resize accordingly.
String name = myProcess.SelectedTab.Name;
Process pHandle = (Process) sessions[name];
MoveWindow(pHandle.MainWindowHandle, 0, 0, this.Width, this.Height, true);

Cannot change position of the MonthCalendar popup of the datetimepicker Winform control

I'm currently developing a custom datetimepicker control that derives from the standard datetimepicker control.
The problem is I cannot change the position of the monthcalendar popup when dropped down.
Here is my code that shifts the monthcalendar popup control to the left by 50px and it works for the control but not the popup window below it:
private const int DTM_FIRST = 0x1000;
private const int DTM_GETMONTHCAL = (DTM_FIRST + 8);
private const uint SWP_NOSIZE = 0x1;
[DllImport("User32.dll", SetLastError = true)]
private static extern IntPtr SendMessage(IntPtr h, int msg, int param, int data);
[DllImport("user32.dll", SetLastError = true)]
static extern bool SetWindowPos(IntPtr hWnd, IntPtr hWndInsertAfter,
int X, int Y, int cx, int cy, uint uFlags);
protected override void OnDropDown(EventArgs eventargs)
{
IntPtr monthCalHandle = SendMessage(this.Handle, DTM_GETMONTHCAL, 0, 0);
if (monthCalHandle == IntPtr.Zero)
{
throw new Exception("Cannot get calendar control");
}
bool success = SetWindowPos(monthCalHandle, IntPtr.Zero,
-50, 0, 0, 0, SWP_NOSIZE);
base.OnDropDown(eventargs);
}
Here is what it looks like from the above code. As you can see the control shifted to the left by 50px but not the popup window below it:
So I thought I should get hold of the parent popup window of the monthcalendar control and set it's position and this is what I did:
[DllImport("user32.dll", ExactSpelling = true, CharSet = CharSet.Auto)]
public static extern IntPtr GetParent(IntPtr hWnd);
protected override void OnDropDown(EventArgs eventargs)
{
IntPtr monthCalHandle = SendMessage(this.Handle, DTM_GETMONTHCAL, 0, 0);
if (monthCalHandle == IntPtr.Zero)
{
throw new Exception("Cannot get calendar control");
}
IntPtr parentHandle = GetParent(monthCalHandle);
if (parentHandle == IntPtr.Zero)
{
throw new Exception("Cannot get calendar parent popup");
}
bool success = SetWindowPos(parentHandle, IntPtr.Zero,
-50, 0, 0, 0, SWP_NOSIZE);
base.OnDropDown(eventargs);
}
And nothing changed is what I get:
By the way
No exceptions were thrown when I run the application. I am using VS 2015 Community and the project targets .NET v4.0.
Appreciate your kind advice.
Thanks in advance.

How do I implement mouse click in Awesomium?

I wrote this code to test the Inject mouse method but it is not working for me. The test is supposed to click in the google text box search area, but the box never gets highlighted. Any idea why?
Google's page does load. The code runs (confirmed through break points), but nothing happens.
public partial class Form1 : Form
{
private IWebView webView;
public Form1()
{
InitializeComponent();
initiate();
}
private void button1_Click(object sender, EventArgs e)
{
click(650, 405);
}
private async void initiate()
{
WebSession session = WebCore.CreateWebSession(
#"C:\SessionDataPath", WebPreferences.Default);
webView = WebCore.CreateWebView(
this.ClientSize.Width,
this.ClientSize.Height, session, WebViewType.Window
);
webView.ParentWindow = this.Handle;
webView.Source = new Uri("http://www.google.com");
await Task.Delay(30000);
click(650, 405);
}
public void click(int x, int y)
{
webView.InjectMouseMove(x, y);
webView.InjectMouseDown(MouseButton.Left);
webView.InjectMouseUp(MouseButton.Left);
}
}
I tried to get this code to work with chromium handle by looking at the proper chromium class but it didn't work
private async Task<bool> clickCoorindate(Point point)
{
webView.FocusView();
int x = point.X; // X coordinate of the click
int y = point.Y; // Y coordinate of the click
IntPtr handle = webView.ProcessHandle;
StringBuilder className = new StringBuilder(100);
while (className.ToString() != "Chrome_RenderWidgetHostHWND") // The class control for the browser
{
handle = GetWindow(handle, 5); // Get a handle to the child window
GetClassName(handle, className, className.Capacity);
if (className.ToString() == "Chrome_RenderWidgetHostHWND")
handle = Handle;
}
IntPtr lParam = (IntPtr)((y << 16) | x); // The coordinates
IntPtr wParam = IntPtr.Zero; // Additional parameters for the click (e.g. Ctrl)
const uint downCode = 0x201; // Left click down code
const uint upCode = 0x202; // Left click up code
const uint moveCode = 0x200;
SendMessage(handle, downCode, wParam, lParam); // Mouse button down
SendMessage(handle, upCode, wParam, lParam); // Mouse button up
Thread.Sleep(20);
SendMessage(handle, downCode, wParam, lParam); // Mouse button down
SendMessage(handle, upCode, wParam, lParam); // Mouse button up
return true;
}
As mentioned in the documentation (see: WebViewType), a windowed view captures all input itself and you cannot inject input programmatically using Awesomium API (you could do this as you tried, by sending native Windows messages to the appropriate HWND but it's not suggested and straightforward procedure).
To be able to inject input programmatically using the InjectXXX methods, make sure your view is of type offscreen.
in my XNA game i use a lot Awesomium and this is my InputSystem i've implemented in my awesomium component, it works very well.
note that this is just a part of my class, so some methods aren't here but they are not needed to understand the process
basically in my thread. basically i hook to the messages in my form and relay them to the WebView. Hope this helps

note that in my component, to hook the message pump, i use

my surface in an Offscreen webview so the more complex, this should work for you too
i posted a separated answer to give another direction:
take a look at this gist: https://gist.github.com/robertkhrona/918109
it seems to suggest to do
webView.InjectMouseMove(x,y);
webView.InjectMouseDown(MouseButton.Left);
webView.InjectMouseMove(x,y);
webView.InjectMouseUp(MouseButton.Left);
so moving (to the same position) between the two mousedown/up event
btw i think this shouldn't be needed tho
which version of awesomium are you running?
update:
Remember to set the focus on your WebView before injecting inputs
webView.Focus();
I set the viewtype to offscreen and the injectclick worked fine, when set to window it doesn't work. I don't know why, but I can work with that.

Getting a second IE Window to open on a different display

I'm writing a .exe that is supposed to run as a scheduled task to check if I have required IE windows open running .Xbaps on specific monitors. I have code that checks what URL is supposed to run, if it's not I use this code to launch it, then move it to the correct monitor:
Process myProcess = Process.Start("iexplore.exe", "-new -k " + "http://server01:123/software.client.xbap");
myProcess.WaitForInputIdle();
Thread.Sleep(500);
MoveWindowToMonitor(myProcess.MainWindowHandle, 1);
Window Moving code:
private static void MoveWindowToMonitor(IntPtr windowHandler, int monitor)
{
RECT windowRec = new RECT();
GetWindowRect(windowHandler, ref windowRec);
int width = windowRec.Right - windowRec.Left;
int height = windowRec.Top - windowRec.Bottom;
if (width < 0)
width = width * -1;
if (height < 0)
height = height * -1;
SetWindowPos(windowHandler, (IntPtr)SpecialWindowHandles.HWND_TOP, Screen.AllScreens[monitor].WorkingArea.Left,
Screen.AllScreens[monitor].WorkingArea.Top, width, height, SetWindowPosFlags.SWP_SHOWWINDOW);
}
Running a quick test version of this gets the first IE window open, Xbap launched, and then quickly moves it over to my other monitor. When I run it a second time, without closing the first IE window, I always get InvalidOperationException
"Process has exited, so the requested information is not available."
I've checked my Task Manager as this is happening and I actually get two iexplore.exe items under details the first time I run the task, and only one additional iexplorer.exe for each subsequent execution of the task. I also get one PresentationHost.exe per xbap launched.
Anyone have any idea what I'm doing wrong or a better way to do this?
My end goal is to be able to do this:
Launch IE in Kiosk Mode on monitor 1 with specific url X:
Launch IE in Kiosk Mode on monitor 2 with specific url Y:
After you launch an IE process, it does some funny stuff and that process you have launched can occasionally end right away as another takes over the window.
What I would do is, using the methods below, is EnumTheWindows which would step through every visible window running and look for Internet Explorer or my baseURL. Then I would pass that Window Handle to GetURL and get the specific URL that IE window was running. This allowed me to use ConfirmProcessIsOnProperMonitor() and MoveWindowToMonitor() to get the windows on the proper monitor.

private static bool ConfirmProcessIsOnProperMonitor(IntPtr windowHandler, int monitor)
{
//make sure you don't go to an incorrect monitor
if (monitor >= Screen.AllScreens.Count()) monitor = Screen.AllScreens.Count() - 1;
RECT windowRec = new RECT();
GetWindowRect(windowHandler, ref windowRec);
if (windowRec.Left != Screen.AllScreens[monitor].WorkingArea.Left || windowRec.Top != Screen.AllScreens[monitor].WorkingArea.Top)
return false;
else
return true;

int width = windowRec.Right - windowRec.Left;
int height = windowRec.Top - windowRec.Bottom;
if (width < 0)
width = width * -1;
if (height < 0)
height = height * -1;
SetWindowPos(windowHandler, (IntPtr)SpecialWindowHandles.HWND_TOP, Screen.AllScreens[monitor].WorkingArea.Left,
Screen.AllScreens[monitor].WorkingArea.Top, width, height, SetWindowPosFlags.SWP_SHOWWINDOW);

PowerPoint Viewer Embed issues

I've embedded a PowerPoint Viewer in my main form in order to display a pptx file. I have 2 monitors on my pc and am trying to run the app on my 2nd monitor. When I run the program on monitor 1, everything works as expected. But when I run it on monitor 2 (meaning I change the code to run the app on the 2nd monitor, not run the app and then move it myself to the 2nd monitor), the PowerPoint Viewer opens on the 1st monitor, then moves to the 2nd monitor where the program is running. I believe it has to do with the PowerPoint object not having the parent set properly but not too sure. Here's my code:
[DllImport("user32.dll", EntryPoint = "FindWindow", SetLastError = true)]
static extern IntPtr FindWindow(IntPtr ZeroOnly, string lpWindowName);

IntPtr pptptr = (IntPtr)sw.HWND;
SetParent(pptptr, splitContainerControl.Panel1.Handle);
splitContainerLeft.Panel1.LostFocus += new EventHandler(OnLostFocus);
splitContainerControl.PreviewKeyDown +=new PreviewKeyDownEventHandler(OnPreviewKeyDown);
splitContainerLeft.Panel1.AutoSize = true;
splitContainerControl.Panel1.Focus();
}
private void DisplayOnMonitor()
{
Screen[] sc;
sc = Screen.AllScreens;
this.FormBorderStyle = FormBorderStyle.None;
this.Left = sc[1].Bounds.Width;
this.Top = sc[1].Bounds.Height;
this.StartPosition = FormStartPosition.Manual;
this.Location = sc[1].Bounds.Location;
Point p = new Point(sc[1].Bounds.Location.X, sc[1].Bounds.Location.Y);
this.Location = p;
this.WindowState = FormWindowState.Maximized;
}
I know the PowerPoint Viewer appears when the sst1.Run() method is called, but I tried to make the app invisible before (and after) that but it throws an exception. If there was a way to instruct sst1 which display to open on, then I think it would resolve the issue, but I haven't had any luck with that so far.
Any help is appreciated!
