FE_SetFormulaDirectory

The function FE_SetFormulaDirectory sets the formula directory. The function unloads the old formulas and loads the new formulas.The function can be invoked in OnFormulaStartEval.

svOldDir = FE_SetFormulaDirectory(svDir)

Return Value

svOldDir is a string vector containing the old formula directory.

Parameters

svDir

svDir is a string vector with the new Formula directory. The function concatenates the vector elements by adding a semicolon (;).

Example

The function OnFormulaStartEval is invoked when the user starts a formula evaluation, e.g. by pressing the F9 key. In the following example the directory is set depending of the value of ssCreator in the NC file.

def OnFormulaStartEval(ncid)
{
    if (nc_attinq_datatype(ncid, NC_GLOBAL, "Creator") == NC_CHAR) {
        ssCreator = nc_attget(ncid, NC_GLOBAL, "Creator");
        if (strmatch("*Pasy*", ssCreator)) {
            FE_SetFormulaDirectory("c:/formel1_pasy; C:/formel2_pasy");
            return TRUE;
        } else {
            ssPath = GetProfileString("Formula", ssCreator, "c:/myformula.ini")
            if (ssPath != "") {
                FE_SetFormulaDirectory(ssPath);
            }
        }
    }
    return TRUE;
}
