Problem of getting the value in the byref argument(function which accepts the byref
argument exists in a dotnet dll):
I have a dotnet dll which has got public function with four optional parameters (two
byval and two byref).
This dll function is called from a webmethod to return a value based on the passed
parameters. The problem that we are facing here is, though we are assigning the value
to the byref arguments the value is not reflected at the webmethod side.
Webmethod : public function( ) as string
{
x = generatexml(mapname)
return x
}
private function generatexml(byval mapname as string) as string
{
'x1 and x2 are byval arguments
'x3 and x4 are byref arguments
call ffReturnXmlString(x1,x2,x3,x4)
return x3
}
The function ffReturnXmlString exists in another dotnet dll. This function generates
the xml and assigns the xml string to the passed byref x3 argument, but once the
statement is executed and the control switches to this function the value of x3
becomes nothing. What should be done to retain the value?
please let me know.
