[Solved] How does XScript::invoke work

[mangesh]

I have added the following application level macro to add two numbers using OOBasic IDE in My macros and dialogs section. This macro is added to the CalcLib/Module1.

Code: Select all

Function UGADD( int1 as Integer , int2 as Integer) as Integer

Dim total as Integer
total =  int1 + int2
UGADD = total

End Function

I call the macro from an external C++ application using the following code

Code: Select all

           Any aCtx;
            aCtx <<= OUString(); // This indicates OOoBasic script.
            Reference <XInterface> iFactory = rOfficeServiceManager->createInstance(
                                                    OUString( RTL_CONSTASCII_USTRINGPARAM(
                                                    "com.sun.star.script.provider.MasterScriptProviderFactory" )));

            
            if ( iFactory.is() )
            {
                Reference< XScriptProviderFactory > xFactory(iFactory, UNO_QUERY );
                Reference<XScriptProvider> xScriptProvider = xFactory->createScriptProvider(aCtx);
                        
                if ( !xScriptProvider.is() )
                {
                    printf("ExecuteOOoBasicCommand() Failed to create ScriptProvider");
                    return 1;
                }

                Reference<XScript> xScript = xScriptProvider->getScript(OUString( RTL_CONSTASCII_USTRINGPARAM                         ("vnd.sun.star.script:CalcLib.Module1.UGADD?language=Basic&location=application")));
            
                
                if ( !xScript.is() )
                {
                    printf("ExecuteOOoBasicCommand() Failed to obtain XScript");
                    return 1;
                }
                
                Sequence< Any  > inArgs(2);
                                
                Any aInt1 , aInt2;
                sal_Int32 i = 24, j = 26;
                aInt1 <<= i;  
                aInt2 <<= j;               

                inArgs.getArray()[0] = aInt1; // Input1 is 24
                inArgs.getArray()[1] = aInt2; // input2 is 26 
                

                Sequence< Any > outArgs;                
                Sequence< sal_Int16 > outIndex;

                xScript->invoke(inArgs,outIndex,outArgs);      

                
                sal_Int32 out1 = 0, out2 = 0;
                sal_Int32 in1= 0, in2 = 0;
                Any result;

                sal_Int32 len = outArgs.getLength();
                sal_Int32 num = outIndex.getLength();
                sal_Int32 num1 = inArgs.getLength();

                sal_Int16 val1 = 0, val2 = 0;

                inArgs[0] >>= in1;  // This value is 24 as above
                inArgs[1] >>= in2;  // This value is 26 as above

                outArgs[0] >>= out1; // This value is 24 
                outArgs[1] >>= out2; // This value is 24
                                
                outIndex[0] >>= val1; // This value is 0
                outIndex[1] >>= val2; // This value is 0
                
                sal_Int32 retVal;
                
                if( outArgs.getArray()[0] >>= retVal ) // This is incorrectly returned as the first input value.
                {
                    printf( "int successfully extracted %d!\n"  , retVal );
                }

            }

I need help in getting the output value from this call. I checked out the information at the following link,
http://www.openoffice.org/api/docs/comm ... cript.html

But I cant get the above working. Please help me in getting this sorted out.

thanks

I'd suspect that it works exactly as documented. The method takes exactly one URL string and 3 arrays as arguments. The second array has short integer indices. Do not expect that anybody will debug your code. This is entirely your job.

Simply keep the return value of the invoke method.

Hi Hanya,
I think I missed the return from the invoke. I was looking for the result in the outParams.
thanks for pointing this out.
