Provides the failure error code returned by a component function.
$ObjErrCode
Number (LONGINT). Can be reset by an application program.
The variable gives the failure error code returned by a component function. This variable is set to $null when a component operation triggers a Zim error and is set to a meaningful value when a Zim 5207 error is encountered.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Destroy an ActiveX object.
$ObjDestroy (Object)
| Object | a component object variable or formfield of type OLE |
Returns a boolean; TRUE if the object was destroyed.
In Zim 7.1, setting an object to $Null will also destroy it. This is the preferred method of releasing an object. For example:
Let MyObj = $Null
Instead of
$ ObjDestroy(MyObj)
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Explains the most likely cause of the last error to occur during the application session.
EXPLERR
File system path to the directory to be used for Cut, Copy, and Paste operations that involve user interface objects in the Screen Painter.
$clippath
A character string. Cannot be reset by an application program.
$ClipPath is set to the value of the ClipPath entry in the registry, or the value of the [ZIM] environment variable. If neither of the preceding values is set, the variable is set to the null string (which is interpreted as the current disk directory).
To indicate the current ClipPath directory in a file name, start the name with a tilde (~) character.
Note: How $ClipPath is set depends on the operating system under which the software is running.
Provides the name of the ActiveX object that triggered an exception.
$ObjErrObjectType
Character string (VARALPHA). Can be reset by an application program.
The variable gives the name of the ActiveX object that triggered an exception in the component. This variable is set to $null when a component operation triggers a Zim error but is set to a meaningful value when a Zim 5207 error is generated.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Provides a description of the error that triggered an exception.
$ObjErrDescription
Character string (VARALPHA). Can be reset by an application program.
The variable gives a meaningful description of the error that triggered an exception in the component. This variable is set to $null when a component operation triggers a Zim error but is set to a meaningful value when a Zim 5207 error is encountered.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
Calculates the arccosine of a number.
$acos(number)where
| number | a number, or an expression that evaluates to a number |
Number, with the same number of decimal places as number.
Use $acos to calculate the arccosine (in radians) of a number. The value returned by this function has the same number of decimal places as number. The absolute value of the number must be between 0 and 1.
let vAngle[3] = $acos(0.500)
The preceding command sets the third element of array variable vAngle to 1.047.
Freshly initializes per user entity sets and relationships with data.
INITIALIZE PERUSER objectname
| objectname
| An entity set name or relationship name (with fields).
|
INITIALIZE PERUSER creates a new physical file corresponding to the objectname. It eliminates the need of deleting all data from the object or copying physical files. Also, it doesn’t affect the internal data dictionary nor requires recompilation of programs after executing it.
It can be executed anytime a fresh file is needed.
objectname must be a PerUser object defined in the data dictionary and no longer needs to be indicated in the file “areas.zim”.
Example
If MyCustomer is an entity set defined as per user in the Data Dictionary, then the following statements are valid:
>INITIALIZE PERUSER MyCustomer
>ADD 1000000 MyCustomer FROM …
>FIND MyCustomer
>1000000 selected.
>INITIALIZE PERUSER MyCustomer
>FIND MyCustomer
>0 selected.
Provides the name of the help file that the component provided when an exception was raised.
$ObjErrHelpFile
Character string (VARALPHA). Can be reset by an application program.
The variable provides the name of the help file that the component provided when an exception was raised because of an improper operation. This variable is set to $null when a component operation triggers a Zim error but is set to a meaningful value when a Zim 5207 error is encountered.
COM objects are being discontinued by Microsoft and may not be available in future releases of Zim-X.
