FAQ941C.txt OLE Exception: 'Type mismatch'
Category :VCL
Platform :All
Product :C++Builder 1.x
Question:
When passing Variant arguments to Variant::OleProcedure, I get
an OLE exception "Type mismatch". Why?
Answer:
VCL's implementation of Variant::OleProcedure is broken.
Instead of calling OleProcedure, try doing the following,
Variant vOLEServer = CreateOleObject(...);
variantarg v;
// Initialize v, your arguments to the OLE server's procedure
.
.
.
Procedure p("SomeServerProc");
p << &variantarg; //VCL only supports passing Variants by ref
vOleServer.Exec(p);
