How can you delete crystal report parameters

[INFORMAT]

Hello

I have a CR report with 4 parameters.
On my form I place an OLE control that send these 4 parameters to crystal reports.
I use the following code to fill the parameter fields:

THISFORM.OleControl1.ParameterFields(0) = ...
THISFORM.OleControl1.ParameterFields(1) = ...
THISFORM.OleControl1.ParameterFields(2) = ...
THISFORM.OleControl1.ParameterFields(3) = ...

Then I print my report and after this report I want to print directly an other report that have no parameters.
How can I delete the 4 parameters that I have created with my first report. If I don't delete these parameters, they are used for my second report and these report doesn't allow parameters and the I receive the CR error 20553 that means that I use invalid parameters.

Thanks for your time and answer

THISFORM.OleControl1.ParameterFields(0) = ...

Can't you simply say:

THISFORM.OleControl1.ParameterFields(0) = ""

etc.? Do this just after the report is off to the printer (or CR... whatever works). Alternatively, you could generically do this before each report.

PS. You might have to say = 0 or = .null. or = .F. depending on how these fields work.

Hi Informat,

The Crystal OCX has a Reset method you can call after printing the first report that will reset its properties to their default values.

THISFORM.OleControl1.Object.PrintReport
THISFORM.OleControl1.Object.Reset

Jon,

That's certainly convient. But what if there are perhaps some properties you don't want to change back to default? Do you have to reset them each time, or is there some sort of 'make default' method which can be used? Relatedly, are the defaults stored in the registry or somewhere else? --Dave
