The GdkEventType enumeration provides a list of available event types. These can be used to determine the type of event that has occurred, since you may not always know what has happened. For example, if you connect the button-press-event signal to a widget, there are three different types of events that can cause the signal s callback function to be run: GDK_BUTTON_PRESS, GDK_2BUTTON_PRESS, and GDK_3BUTTON_PRESS. Double-clicks and triple-clicks emit the GDK_BUTTON_PRESS as a second event as well, so being able to distinguish between different types of events is necessary. In Appendix B, you can see a complete list of the events available to you. It shows the signal name that is passed to g_signal_connect(), the GdkEventType enumeration value, and a description of the event. Let s look at the delete-event callback function from Listing 2-2. We already know that delete-event is of the type GDK_DELETE, but let us assume for a moment that we did not know that. We can easily test this by using the following conditional statement: static gboolean delete_event (GtkWidget *window, GdkEvent *event, gpointer data) { if (event->type == GDK_DELETE) return FALSE; return TRUE; } In this example, if the event type is GDK_DELETE, FALSE is returned, and gtk_widget_destroy() will be called on the widget. Otherwise, TRUE is returned, and no further action is taken. convert excel file to pdf using c#: Convert .XLS to .PDF using C# - MSDN - Microsoft convert excel to pdf c# free How to convert Excel to PDF using C# and VB.NET | WinForms - PDF

Sometimes, you may already know what type of event has been emitted. In the following example, we know that a key-press-event will always be emitted: g_signal_connect (G_OBJECT (widget), "key-press-event" G_CALLBACK (key_press), NULL); In this case, it is safe to assume that the type of event will always be GDK_KEY_PRESS, and the callback function can be declared as such. static gboolean key_press (GtkWidget *widget, GdkEventKey *event, gpointer data) function Button1_onclick() { var testCar = new AJAXBook.Car('Honda','Pilot','2005'); alert(testCar.get_MakeandModel()); alert(testCar.get_Year()); var testSUV = new AJAXBook.SUV('Honda','Pilot','2005','Active'); alert("SUV Make and Model: " + testSUV.get_MakeandModel()); alert(testSUV.get_Year()); Since we know that the type of event is a GDK_KEY_PRESS, we will not need access to all of the structures in GdkEvent. We will only have a use for GdkEventKey, which we can use instead of GdkEvent in the callback function. Since the event is already cast as GdkEventKey, we will have direct access to only the elements in that structure. typedef struct { GdkEventType type; GdkWindow *window; gint8 send_event; guint32 time; guint state; guint keyval; gint length; gchar *string; guint16 hardware_keycode; guint8 group; guint is_modifier : 1; } GdkEventKey; convert excel file to pdf using c# Create Excel file and save as PDF. - Stack Overflow

Steps to convert excel document to PDF programmatically: It means that you should avoid unnecessary mechanisms in your code in favor of simplicity In order to keep software simple and security checks localized, you can take advantage of a concept called a choke point A choke point is a centralized piece of code through which control must pass You could, for instance, force all security operations in a piece of software to go through one piece of code For example, you should only have one checkPassword() function in your system all password checks should be centralized, and the code that does the password check should be as small and simple as possible so that it can be easily reviewed for correctness The advantage is that the system is more likely to be secure as long as the code is correct. // // // // // // // // // // // alert(testSUV.get_DriveType()); return false; } GDK_KEY_PRESS or GDK_KEY_RELEASE The window that received the event TRUE if the event used XSendEvent The length of the event in milliseconds The state of Control, Shift, and Alt The key that was pressed <gdk/gdkkeysyms.h> The length of string A string approximating the entered text Raw code of the key that was pressed or released The keyboard group Whether hardware_keycode was mapped (since 2.10) This is all built on the concept that the less functionality one has to look at in a given application, the less security exposure and vulnerability that piece of software will have Software that is simple will be easier to test and keep secure.. There are many useful properties in the GdkEventKey structure that we will use throughout the book. At some point it would be useful for you to browse some of the GdkEvent structures in the API documentation. We will cover a few of the most important structures in this book, including GdkEventKey and GdkEventButton. The only variable that is available in all of the event structures is the event type, which defines the type of event that has occurred. It is a good idea to always check the event type to avoid handling it in the wrong way. c# code to save excel file as pdf C# Converting existed excel file to pdf - MSDN - Microsoft
