ExecStrCommand Method |

Applies to
Declaration
procedure ExecStrCommand(CommandID: Integer; param: Integer; const StrParam: WideString);
CommandID = 1:
Set the state of the field using the parameter 'param' inside the event OnFieldGetText. The State is used for band conditions of the integrated reporting.
0: Default value
1: Field is not known (default if checking field and band conditions, i.e. ?field=null )
2: Field is defined and NULL
3: Field is defined and ZERO
4: Field is defined (set this value unless it is null or zero)
Example - Simulate certain conditions:
private void wpdllInt2_OnFieldGetText(object Sender,
int Editor, string FieldName, IWPFieldContents Contents)
{
// test the conditions
if (!Contents.IsMergefield)
{
if (FieldName == "ISNULL")
Contents.ExecStrCommand(1, 2, "");
else if (FieldName == "ISZERO")
Contents.ExecStrCommand(1, 3, "");
else if (FieldName == "ISUNDEF")
Contents.ExecStrCommand(1, 1, "");
else
{
Contents.ExecStrCommand(1, 4, ""); // Known
Contents.StringValue = "123";
}
} else
....
}
This conditions can be used inside band tokens like in this simplified sample (See Token to Template Conversion):

This method can be extended for custom manipulations of the inserted text - if you have a wish please let us know.
