Parameters:

[in]

aIndexes

The index list to process.

Returns:

List of most bottom indexes.

QString Bps::computerName

(

)

const

Get the computer name.

The computer name taken from the environment variables COMPUTERNAME. For fat clients COMPUTERNAME is the name of the workstation. For thin clients COMPUTERNAME is the name of the terminal server.

Returns:

The computer name as string.

QString Bps::createTempFile

(

const QString &

aTemplate = QString()

)

const

Creates a temporary file and returns the complete file name.

It is purpose of the application to delete the file when it is no longer needed.

In most cases it will be more convenient to use QTemporaryFile, however there are special cases like when printing where you need to provide a file name and the class will open, write and close the file itself.

Parameters:

[in]

aTemplate

A file name template, as in QTemporaryFile.

Returns:

The name of the created file.

int Bps::decryptPin	(	int	aUserid,
		int	aPin
	)		const

Decrypt a user PIN.

Parameters:

QStringList Bps::directionTexts

(

const

Returns:

QString Bps::directory

(

const QString &

aName = QString()

)

const

Get a BPS application directory.

The path is first searched in the environment where aName is prefixed with "BPS_".

When the path was not found in the environment variables, it is searched in the file bps.conf which is in the directory where the executable was started from. The key aName is expected in section [Paths].

If the found path is relative (not starting with a drive or slash/backslash), it is assumed to be relative to the BPS installation directory (one above the exe's). The returned path is made absolute under this premise.

Example 1: Relative path in environment variable

aName	Logs
Environment variable BPS_LOGS=	mylogs
BPS installation directory	C:\Program Files\IBK BPS 2.0.0
Returned path	C:/Program Files/IBK BPS 2.0.0/mylogs

Example 2: Relative path in bps.conf

aName	Logs
Environment variable BPS_LOGS=	(not found)
bps.conf: [Paths] ... Logs=	logs
BPS installation directory	C:\Program Files\IBK BPS 2.0.0
Returned path	C:/Program Files/IBK BPS 2.0.0/logs

Parameters:

[in]

aName

Logical path name, for example: Logs, CSS, Plugins or Scripts. Get the BPS installation directory if aName is empty.

Returns:

The absolute path, or empty string if path unknown.
