Origin Version: OriginPro 7.5 SR6 v7.5885(B885)
Operating System: Windows XP Pro SP2

I would like to work with an ADO Connection object and an ADO Command object. I have the following code:

static Object occnxn;
static Object occmd;
BOOL testCXN()
{
string strConn;
occnxn = CreateObject("ADODB.Connection");
if( !occnxn )
return FALSE;
strConn = "Provider=SQLOLEDB; Server=jayg; Database=flocis; User ID=jay; WSID=JAYG; Trusted_Connection=Yes";
occnxn.open(strConn);
occmd = CreateObject("ADODB.Command");
if( !occmd )
return FALSE;
occmd.ActiveConnection = occnxn; // ERROR HERE
/* more code later */
occnxn.Close();
return TRUE;
}

The line marked "// ERROR HERE" gives me this compile error:
Error, Incompatible variable types in expression

Microsoft's docs say the ActiveConnection property is expecting a variant. I am confused by their Visual C++ code example, however. Can anyone help me figure out how to make the ActiveConnection property assignment?

Hi Jay,

The assignment you are trying is not possible in 7.5. I can't think of a workaround.

I was able to find a workaround by using the Execute method of the ADO Connection object:

occnxn = CreateObject("ADODB.Connection");
if( !occnxn )
return FALSE;
strConn = "Provider=SQLOLEDB; Server=jayg; Database=flocis; User ID=jay; WSID=JAYG; Trusted_Connection=Yes";
occnxn.open(strConn);
occnxn.Execute("spChangePipeSize @HeaderID=1,@NewSize='20'",NULL,0x88);
occnxn.Close();

[not sure why the underline is there - j]
