Report Is Not Change

[Erfan Gholami]

I Found that StimulReport Have a bug in this Case
I Load a Report From Byte Array In Function A
.
.
Function A()
.
.
report.LoadPackedReport(buff)
.
.
End Function
.
.
And I Use Report In function B More Than One Time
.
.
Function B()
.
.
report.RegData(MyDataSet)
report.Render()
.
.
End Function
.
.
It work in fist time that i call Function B
But When I Call it again it dos not Work .
It throw an exception : "Invalid Parameter" Or "Invalid character in a Base-64 string"
OR It Show Fields In Mistake Position For Example Display "Field Alpha Data" In "Field Beta Position"
I Use Your Offered Code(DataStore.Clear() OR Dictionary.Clear() OR Dictionary.Synchronize() ) And I Check MY Dataset Data Several Times But It's not work Yet
But when I Use This Code :

Function B()
.
.
report.LoadPackedReport(buff)
report.RegData(MyDataSet)
report.Render()
.
.
End Function
it work successfuly but ReLoading the report is Time Consuming . and I can not ReLoad ReportContent every time i want to render the Report.
Please tell me what i should do to solve this problem
Thanks

hi
My problem Was Solved
The Problem was that I save My Dataset To Bank and Fetch it when need.
But When I Save It To Bank I Dont Write SChema Of Dataset And I Use This Code

Code: Select all

.
.
MyDataSet.WriteXml(MyBinaryWriter)
.
.

and i read dataset with this code

Code: Select all

.
.
MyDataSet.ReadXml(MyStreamReader)
.
.

When We Use "MyDataSet.WriteXml(MyBinaryWriter)" The Schema Of Dataset that Contains Type Of Each Columns Is

not Save and StiReport Can Not Match The Dataset Columns With His Dictionary Columns And Throw Some Exception

When We want To Save Our Dataset To A File Or Stream We Must Save "Data And Schema" both With These Codes:

Code: Select all

MyDataSet.WriteXml(MyBinaryWriter , XmlWriteMode.WriteSchema)
.
.
MyDataSet.ReadXml(MyStreamReader  , XmlReadMode.ReadSchema )

The StimulReport Is The Best Reporting Tool I Know With the great Supporting Service . But it is Expensive :grinder:
