Syntax

Visual Basic

Property ALCD(lALID As Long) As Integer


Visual C++

short GetAlcd(long lALID)
void SetAlcd(long lALID, short nNewValue)


ArgumentDescription
lALIDAlarm ID

Return Value

Example

If ALID was not registered, user cannot set value. If user wants to get the list of registered ALID, take following steps.

First, read ALIDCount property value.

Visual Basic

Dim lCount As Long
lCount = .ALIDCount


Visual C++

long lCount = m_ctrl.GetALIDCount();


Since ALIDCount property returns the number of registered ALID, the index should be between 0 and (ALIDCount - 1). Convert index into ALID using ToALID method.

Visual Basic

Dim lALID As Long
lALID = .ToALID(0)


Visual C++

long lALID = m_ctrl.ToALID(0);


Once ALID were determined, it is possible to access ALCD property and ALTX property.

Visual Basic

Dim nALCD As Integer
nALCD = .ALCD(lALID)


Visual C++

int nALCD = m_ctrl.GetAlcd(lALID);


Enumerate all the ALIDs using “for” loop. Following is the entire source code.

Visual Basic

Dim lCount As Long
lCount = .ALIDCount

Dim lCnt As Long
For lCnt = 0 to lCount – 1
    Dim lALID As Long
    lALID = .ToALID(lCnt)

    Dim nALCD As Integer
    nALCD = .ALCD(lALID)

    Dim strALTX As String
    strALTX = .ALTX(lALID)
Next lCnt


Visual C++

long lCount = m_ctrl.GetALIDCount();
for(long lCnt=0;lCnt<lCount;lCnt++)
{
    long lALID = m_ctrl.ToALID(0);
    int nALCD = m_ctrl.GetAlcd(lALID);
    String strALTX = m_ctrl.GetAltx(lALID);
}

Remarks

When value was set in ALCD property, only lower 7-bit would be recorded. The highest bit of ALCD is used for "alarm set" or "alarm cleared". This bit can be changed by InvokeAlarm method (use argument).
