RE: (forte-users) Any inputs on PutFormulas(...) method ofCrystal Repor

Question

Hi Jagadish,
The OLE error code of 0x80020003 translates to "Member not found." This may
indicate that the parameter is not properly defined as a Parameter field in
the Crystal Report you're using.
Additionally, the date format you're using is wrong. Crystal requires that
you pass a date as "Date(yyyy, mm, dd)." Your example, then, should read:
l_tdParam : TextData = New();
l_tdParam.SetValue('Date(2000, 03, 15)');
l_CrystalRepObj.PutParameterFields(0, l_tdParam.Value);
I hope this helps.

Crystal Report's ActiveX object
Hi Katie,
I am thankful for your time and effort.
I have a problem here. I did exactly the way you have suggested, but I get
this
exception.
SYSTEM ERROR: Error during Invoke; status code: -2147352573(0x80020003)
Class: OLEException with ReasonCode: OLE_ER_RESOURCE
Last TOOL statement: method DebugState.RaiseException
The parameter I want to set is a date type. This is the only parameter in
the
report.
First trial:
l_tdParam : TextData = New();
l_tdParam.SetValue('03/15/2000');
l_CrystalRepObj.PutParameterFields(0, l_tdParam.Value);
Second Trail:
l_dtdParam : DateTimeData = New();
l_dtdParam.SetCurrent(DR_DAY);
l_CrystalRepObj.PutParameterFields(0, l_dtdParam.TextValue.Value);
Do you think I am going wrong somewhere here. Please suggest.
Once again, I am thankful for your time and effort.

May I suggest:
1. Talk to Forte Consulting and get ReportKit. It's inexpensive, and the
Forte Consultant can help you get it set up quickly. It's a great product.
2. The following code has worked for me in the past (I have no way of
testing it now, but think it should still work):
// ptd_Parameter_Array is an ARRAY of TextData containing the
// VALUES to be placed in the parameter fields.
// Since Crystal Reports uses a zero-based array numbering
// scheme, we need to set up a counter and set its initial
// value to 0.
li_Counter : integer = 0;
for eachParam in ptd_Parameter_Array do
self.PutParameterFields(index = li_counter, param2 =
eachParam.Value);
li_Counter = li_counter + 1;
end for;
The VariantVoidResult is NIL by default, and you shouldn't need to worry
about it at all. It's the result that the Crystal OCX sends back to Forte.
The Index starts at 0, and continues to the number of parameters - 1.
The Param2 value is the string that contains the actual parameter value.
For example, if I have defined a Crystal parameter called "Country," then I
would send "USA" as the string value for param2.
I hope this helps (and I STRONGLY suggest ReportKit).
Regards,
-Katie

Subject: (forte-users) Any inputs on PutFormulas(...) method of Crystal
Report's ActiveX object
Hi,
Could someone give me inputs on how to use PutFormulas(index: i2, param2:
string, _VariantVoidResult = NIL) method of Crystal ActiveX object.
I want to use this method to modify Crystal Report formulas. I would like to
know
1. index parameter - what is the domain, or expected values to this
parameter
2. param2 parameter - How to formulate this?; a sample template please;
3. _VariantVoidResult parameter - what is the significance of this
parameter?
A working example will help me a lot.
Thanks in advance.
