Hi,
I want to write 64bit TDM export programme in programming language Delphi. The problem I have is that function DDC_AddChannel always returns error code -6203 which means the wrong datatype was added to function. But for 32bit version works.
I call function like:
DDC_AddChannel(ChannelGroup, DDC_Float, PFieldName, PChNum, PFieldUnit, @channel);
The DDC_Float is defined in enum DDCDataType. The enum looks like:
type
DDCDataType= (
DDC_notype {= 0},
DDC_UInt8 {= 5}, // unsigned char
DDC_Int16 {= 2}, // short
DDC_Int32 {= 3}, // int
DDC_Float {= 9}, // float -> single
DDC_Double {= 10}, // double
DDC_String {= 23}, // string
DDC_Timestamp {= 30} // timestamp
);
So where is the problem ?
Thanks for the answers in advance.
Kind regards,
Primus
