Examples
This example is an excerpt of the example in the class overview of InstallContext class.
It uses the IsParameterTrue method to find out if the LogtoConsole parameter has been set. If yes, it will then use the LogMessage method to write status messages to the installation log file and the console.
// Check whether the "LogtoConsole" parameter has been set.
if ( myInstallContext->IsParameterTrue( "LogtoConsole" ) )
{
// Display the message to the console and add it to the logfile.
myInstallContext->LogMessage( "The 'Install' method has been called" );
}
// Check whether the "LogtoConsole" parameter has been set.
if( myInstallContext.IsParameterTrue( "LogtoConsole" ) == true )
{
// Display the message to the console and add it to the logfile.
myInstallContext.LogMessage( "The 'Install' method has been called" );
}
' Check wether the "LogtoConsole" parameter has been set.
If myInstallContext.IsParameterTrue("LogtoConsole") = True Then
' Display the message to the console and add it to the logfile.
myInstallContext.LogMessage("The 'Install' method has been called")
End If
Remarks
An installer can call this method to write progress or other status information to the log file. If the command-line parameters specify that a user interface should be displayed, the installer should show message boxes or make queries in addition to calling the LogMessage method. Text written to the log file will not be seen by the user unless InstallUtil.exe is used to run the installation and "/LogToConsole= true" is specified in the command line.
