Hi,
I am facing some problems when passing array from javascript to COM components:
The code is working properly for VBSCript.
When I checked the datatype for this array, I am getting the different values:
for VBScript it is showing as VT_ARRAY and for Javascript as VT_DISPATCH.
Because of this I am not able to get the array members in VC++ component.
PLease suggest me how to resolve this?
Javascript code:
----------------
function main()
{
var procName;
var prmIn = new Array(1); prmIn[0] = "g1";
prmIn[1] = "g2";
var boolValue;
boolValue = myAPI(prmIn);
if(boolValue == 0)
{
logMessage(1, "ERR: executeSPOutParams failed");
}
else
{
logMessage(1, "executeSPOutParams PASS");
}
} COM code:
----------
HRESULT test::myAPI(VARIANT* varInParams)
{..................
VARIANT *varArrParams;
try
{
long lParamCount = 0;
HRESULT hr;
if(varInParams->vt == (VT_VARIANT|VT_BYREF|VT_ARRAY))
{
//Input SP parameter SAFEARRAY** ppsa = (SAFEARRAY**)varInParams->pparray;
hr = SafeArrayGetUBound(*ppsa, 1, &lParamCount);
SafeArrayAccessData(*ppsa, (void **)&varArrParams); for(long lPrmCount =
0 ; lPrmCount <= lParamCount; lPrmCount++)
{
//data here varArrParams[lPrmCount]);
}
SafeArrayUnaccessData(*ppsa);
}
else if(varInParams->vt != VT_EMPTY)
{
..........................
}
.....................
} For Vb script if part is executed and for and for javascript it goes to else
part. Please suggest me if it is VT_DISPATCH how to get the array values?
Thanks & Regards
