Namespace: PPJ.Runtime.Windows

Assembly: PPJ.Web.49 (4.9.0.0)

Base class for SAL applications.

public class SalApplication

Public Class SalApplication

Constructors

SalApplication()

Properties

ApplicationType

Type: Returns the type of the application.

CompanyName

String: Returns the company of the application loaded from the AssemblyCompany attribute;

DefaultPrinterSettings

PrinterSettings: Returns the default printer settings. This is set by SalPrt

SalApplication: Singleton instance of the SalApplication object. When this is the main SalApplication object, the instance is created as the startup form. References assemblies, instead, create their session instance of the SalApplication object upon accessing the Instance singleton property.

Applications can have multiple instances of the SalApplication object, one for each ported assembly. Each SalApplication class belongs necessarily to a different namespace.

String: Returns the title of the application loaded from the AssemblyTitle attribute;

Form[]: Returns a list of all top-level forms that belong to this application.

Int32: Returns the version of the framework.

Methods

Increase the reference count for the application object. It is called every time a new SalForm is created.

Returns: Int32. Updated reference count

Disables input to all open forms. Use SalAppDisable and SalAppEnable when there are multiple applications running simultaneously and you want to control which application receives user input.

Returns: Boolean. bOk

Enables input to all open forms that were disabled by SalAppDisable. Use SalAppDisable and SalAppEnable when there are multiple applications running simultaneously and you want to control which application receives user input.

Returns: Boolean. bOk

Stops all tracing. Any calls to SalTrace() occurring after SalEndTrace() will be ignored.

Returns: Boolean.

Retrieves the integer value of an entry in the specified section of an initialization file or registry.

Returns: UInt32.

Returns: Int32.

Executes javascript on the client.

Starts an application.

Returns: Boolean.

Returns: Boolean.

Forces the termination of the application.

Forces the browser to reload the document. It's necessary when changing the Mdi tabbed layout and may come handy for other live changes.

Decreases the reference count for the application object. When the count drops to zero (or below if there is a bug), the application exits. It is called every time a Sal form is destroyed. This should emulate SAL application's behavior with respect to top level windows. When the last form is destroyed the app exits.

Returns: Int32.

Main method to startup a SAL application.

Returns: Int32.

The SAL application class that extends SalApplication should call this method in the application's Main form OnLoad() method.

public class MainForm : Form
{
  protected override void OnLoad(EventArgs e)
  {
    new App().Run();
  }
}

Set the value of an entry in the specified section of an initialization file or registry. All profile information is stored as string, so if you want to store an integer it must be converted to a string first. Then it can be retrieved as an integer using the SalGetProfileInt- Function .

Returns: Boolean. bOk

Allows tracing to begin.

Returns: Boolean.

Outputs a string to the trace output target selected earlier in the SalStartTrace function. Note that if tracing is not already activated, this function will return TRUE even though no trace action is taken. When writing to the event log, the severity level is kept in numeric form. When writing to any other output target, it is translated into a text string such as "Warning".

Returns: Boolean.

Enables logging of unhandled exceptions in the event log.

Returns: Boolean.

This function is used to re-direct all SalProfile* functions to use the Registry. All values for the SalProfile* functions are saved as strings. The INI file name used as the last parameter of the SalProfile* functions will be used as the application name. The resulting path will be: \HKEY_CURRENT_USER\Software[company name][application name][section][setting]\

Returns: Boolean. bOk
