Hi,
I am having a problem with a stored procedure. I am getting the
following error
ADODB.Command error '800a0d5d'
Application uses a value of the wrong type for the current operation.
/myproofs/includes/functions.asp, line 183
I have higlighted line 183 with #######
FUNCTION addPublication( strName, dtCreationDate, dtDeadlineDate, blnOpen)

Bad practice here. Always use Set when assigning an object to a variable or
property. Without the Set keyword, the default property of objConn (its
connection string) is assigned to ActiveConnectio n. This causes a new
connection to be implicitly created and opened when you execute the Command,
in effect, disabling session pooling.
objComm.Command Text = "Insert_Add_Pub lication" objComm.Command Type = adCmdStoredProc
objComm.Paramet ers.Append objComm.CreateP arameter("@tblP ublicationName" , adVarChar,adPar amInput,50,strN ame) objComm.Paramet ers.Append ######objComm.C reateParameter( "@tblPublicatio nCreationDate", adDBDate,adPara mInput,4,dtCrea tionDate)
1. The correct datatype constant to use is adDBTimeStamp
2. You need to verify that dtCreationDate actually contains a date. Use
CDate with error-handling to do this verification. If dtCreationDate
contains an empty string, you need to assign Null to the variable.
3. You don't have any output parameters that I can see, and you don't seem
to be interested in reading the return parameter, so you do not need an
explicit Command object., using the "stored-procedure-as-connection-method"
technique to execute your procedure instead. You can rewrite your function
as follows:
FUNCTION addPublication( strName, dtCreationDate, dtDeadlineDate, blnOpen)
' validate your inputs per step 2 above, then:
on error resume next
objConn.Insert_ Add_Publication strName, dtCreationDate, blnOpen, _
dtDeadlineDate
if err <> 0 then
'handle the error
end if
end function
I only use an explicit Command object when
a. I need to read the value of the return parameter
b. I need to use output parameters
c. both of the above

And what does that imply WRT JScript (where there is no Set keyword) and
connection pooling?

If you check out the "Implicit Connections" thread started by Mark McGinty,
you will see me eating crow about this. It turns out that the Set keyword is
actually not needed in this situation for some reason. Somehow, the
ADODB.Command class is handling it the way it should be handled.
I do not believe this issue would have any bearing wrt jscript anyways,
since, as you say, there is no equivalent of a Set keyword in that language.

And perhaps just as importantly, no default properties.

Hello,
I am trying to build the boost 1.31.0 sample extension hello.cpp.
