Public Function IsParameterTrue ( _

) As Boolean
Dim instance As InstallContext
Dim paramName As String
Dim returnValue As Boolean
returnValue = instance.IsParameterTrue(paramName)

public function IsParameterTrue (

) : boolean
Parameters
- paramName
The name of the command-line parameter to check.
Return Value
true if the specified parameter is set to "yes", "true", "1", or an empty string (""); otherwise, false.
This method accesses the Parameters property, which contains a parsed version of the command-line parameters, to determine whether the specified parameter is true.
This example is an excerpt of the sample in the class overview of the 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 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
// 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 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");
