Hi

BDS2006 (C++Builder).

A DLL with any of the following "TADOConnection", "TADOCommand",
"TADOTable->GetIndexNames()", "TADOCommand->Execute()",
"TADOQuery->SQL" will fail to build if the "Build With Runtime Packages"
project option is unchecked. Builds OK if checked.

Any workaround ?

I added the 2 libs as you mentioned to the DLL project and it solved the
problem. Thanks.

For your information, examples of the errors as follows:-

[Linker Error] Error: Unresolved external '__fastcall
Adodb::TADOCommand::TADOCommand(Classes::TComponent *)' referenced from
C:\PROGRAM FILES\BORLAND\BDS\4.0\PROJECTS\DLLFILES\DEBUG_BUILD\DLLDB.OBJ
[Linker Error] Error: Unresolved external '__fastcall
Adodb::TADOTable::GetIndexNames(Classes::TStrings *)' referenced from
C:\PROGRAM FILES\BORLAND\BDS\4.0\PROJECTS\DLLFILES\DEBUG_BUILD\DLLDB.OBJ
[Linker Error] Error: Unresolved external '__fastcall
Adodb::TADOQuery::GetSQL()' referenced from C:\PROGRAM
FILES\BORLAND\BDS\4.0\PROJECTS\DLLFILES\DEBUG_BUILD\DLLDB.OBJ

Only the ADO references mentioned caused Linker Errors. Many other ADO
references
in the DLL caused no Linker Error messages.

The following function works OK when used within a project :-

// Assemble End of Report message with to-days date and time
String EndOfReport() // Within Project
String __declspec(dllexport) EndOfReport() // DLL
{
String dateString, timeString, endOfReport;

dateString = Date();
timeString = TimeToStr(Time());
AV endOfReport = " End of Report --- Date Printed: " +
FormatDateTime("dddddd",dateString) + " at " +
timeString.SubString(1,5);

return endOfReport;
}

When called from a DLL it works the first time when printing a report.
When it is called a second time it fails with an AV on the line marked
and the debugger shows GETMEM.inc

Any help appreciated.
