Make your C# form go fullscreen

Many applications have the ability to go fullscreen. Here’s a simple snippet which will make your form go fullscreen and restore to its original location.

For testing purposes, I’ve attached a very simple KeyDown event which checks for F11 keypresses (the standard fullscreen keyboard shortcut in many applications).

using System.Drawing;
using System.Windows.Forms;

namespace Danny_GB_Net {
public partial class FullscreenForm : Form {
// struct containing key information needed to restore the form to its original size/state
struct FullscreenRestoreState {
public Point location;
public int width;
public int height;
public FormWindowState state;
public FormBorderStyle style;
};
FullscreenRestoreState restoreState;

// used in ToggleFullscreen so that the program knows whether it needs to go fullscreen or restore
bool isFullscreen = false;

// standard constructor
public FullscreenForm() {
InitializeComponent();

// attach a test event
KeyDown += new System.Windows.Forms.KeyEventHandler(KeyDownEventHandler);
}

void ToggleFullscreen() {
if (!isFullscreen) { // save state information to restoreState and go fullscreen
restoreState.location = Location;
restoreState.width = Width;
restoreState.height = Height;
restoreState.state = WindowState;
restoreState.style = FormBorderStyle;

TopMost = true;
Location = new Point(0, 0);
FormBorderStyle = FormBorderStyle.None;
Width = Screen.PrimaryScreen.Bounds.Width;
Height = Screen.PrimaryScreen.Bounds.Height;
} else { // restore from restoreState
TopMost = false;
Location = restoreState.location;
Width = restoreState.width;
Height = restoreState.height;
WindowState = restoreState.state;
FormBorderStyle = restoreState.style;
}

// toggle our variable
isFullscreen = !isFullscreen;
}

// event for testing purposes
private void KeyDownEventHandler(object sender, KeyEventArgs e) {
if (e.KeyCode == Keys.F11) {
ToggleFullscreen();
}
}
}
}

using System.Drawing;

using System.Windows.Forms;

namespace Danny_GB_Net {

public partial class FullscreenForm : Form {

// struct containing key information needed to restore the form to its original size/state

struct FullscreenRestoreState {

public Point location;

public int width;

public int height;

public FormWindowState state;

public FormBorderStyle style;

};

FullscreenRestoreState restoreState;

// used in ToggleFullscreen so that the program knows whether it needs to go fullscreen or restore

bool isFullscreen = false;

// standard constructor

public FullscreenForm() {

InitializeComponent();

// attach a test event

KeyDown += new System.Windows.Forms.KeyEventHandler(KeyDownEventHandler);

}

void ToggleFullscreen() {

if (!isFullscreen) { // save state information to restoreState and go fullscreen

restoreState.location = Location;

restoreState.width = Width;

restoreState.height = Height;

restoreState.state = WindowState;

restoreState.style = FormBorderStyle;

TopMost = true;

Location = new Point(0, 0);

FormBorderStyle = FormBorderStyle.None;

Width = Screen.PrimaryScreen.Bounds.Width;

Height = Screen.PrimaryScreen.Bounds.Height;

} else { // restore from restoreState

TopMost = false;

Location = restoreState.location;

Width = restoreState.width;

Height = restoreState.height;

WindowState = restoreState.state;

FormBorderStyle = restoreState.style;

}

// toggle our variable

isFullscreen = !isFullscreen;

}

// event for testing purposes

private void KeyDownEventHandler(object sender, KeyEventArgs e) {

if (e.KeyCode == Keys.F11) {

ToggleFullscreen();

}

Compile the wxWidgets source – batch script

When setting up a development environment for wxWidgets, it’s usually necessary to compile your own binaries from the source. This can be a tedious task, so I threw together a simple batch script which simplifies the whole process.

Note: As of 2.9.5, it is possible to download pre-built binaries for Visual C++ users.

@ECHO OFF

REM Prompt the user to enter the path to MinGW compiler

ECHO Please enter the path to MinGW (NOTE: It should not contain spaces.
ECHO If it does, it is recommended that you put it in the root of your C drive
ECHO (example, C:\MinGW\bin)

REM Get the input

SET /p PATH=

REM Prompt the user to enter the path to wxWidgets

ECHO Please enter the installation path of wxWidgets
ECHO (example, C:\wxWidgets-2.8.9)

REM Get the input

SET /p WX=

ECHO Executing... Go get a coffee, this may take a while ;)

REM Move into the WX directory

cd %WX%\build\msw

REM First we need to clean the source

@ECHO ON

%PATH%\mingw32-make -f makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release clean
REM Now compile it

%PATH%\mingw32-make -f makefile.gcc MONOLITHIC=1 SHARED=1 UNICODE=1 BUILD=release
ECHO Aaaaand... we're done. Did you enjoy your coffee? :)

ECHO Press any key to exit

WP-Members: Automatically login after registration

WP-Members is a fantastic plugin for securing various areas of your WordPress site for access by registered users. While extremely versatile, not everything can be controlled through the settings alone.

An often-requested feature is for the plugin to automatically login a user after they have registered. Unfortunately, this functionality is unavailable in the current version of the plugin. However, by adding an action to WP-Members’ wpmem_post_register_data tag, it becomes possible to add this extra functionality. The following can be added to your plugin file, or even to your theme’s functions.php file:

add_action('wpmem_post_register_data', 'my_registration_hook', 1);

function my_registration_hook($fields) {
	$user_login = $fields[username];
	$user_id = $fields[ID];

	wp_set_current_user($user_id);
	wp_set_auth_cookie($user_login);
	do_action('wp_login', $user_login);

	wp_set_current_user($fields[ID]);
}

add_action('wpmem_post_register_data', 'my_registration_hook', 1);

function my_registration_hook($fields) {

$user_login = $fields[username];

$user_id = $fields[ID];

wp_set_current_user($user_id);

wp_set_auth_cookie($user_login);

do_action('wp_login', $user_login);

wp_set_current_user($fields[ID]);

}

Note: At the time of writing, the current production version of WP-Members is 2.8.2
