using the DataFlex development, by that using the DLL interface
Using DebWin4 to sort out a problem.
It reports:
<LlPrintGetOptionString() → -18 (0xffffffee) (Parameter error. Please use debug mode to determine the error.)
If have set the debug mode to
LlSetDebugEf to LL_DEBUG_CMBTDWG and the debug mode is on.
So see all messages in Dedbwin4.
So I must be missing something because it still complains……

Can you paste the full context? Usual suspects would be using an invalid option constant or querying a print option without actually printing. A full log should help to troubleshoot the issue.
This

looks like it should rather be a call to LlGetOptionString or LlSetOptionString. Then, the constants passed would make more sense as they would resolve to
#define LL_OPTIONSTR_EXPORTS_AVAILABLE (17 ) /* r/o */
#define LL_OPTIONSTR_EXPORTS_ALLOWED (18 )
I was unable to find these calls in our DataFlex sample - are you positive they’re in there? Can you give me the full file name of the source file in this case?
tldr: change the call to use LlSetOptionString and LlGetOptionString and move the calls before LlPrint(WithBox)Start. That should help.
Here is the source I was toying with to sort out how I want my framework to work/look and feel
Just send did not look at you remarks.
LLInvoice.zip (5.1 KB)
Replace in the sample.
I always used Crystal. So wanted a bit or the same look and feel
This is my preview.
Will now look at you remarks

If I move it before the
LLPrintWithBoxStart
Call I get -4 as result “Print job not opened, no Print Object”
Peter
Here’s the culprit:
If (iDest=LL_PRINT_EXPORT) Begin
//LlSetOptionString(hJob, LL_OPTIONSTR_EXPORTS_ALLOWED,"PRV;HTML");
String sDummy_1
String sDummy_2
Get LLPrintGetOptionString of hoLL LL_OPTIONSTR_EXPORTS_ALLOWED to sDummy_1
Get LLPrintSetOptionString of hoLL LL_OPTIONSTR_EXPORTS_AVAILABLE "PRV;HTML" to iRet
Get LLPrintGetOptionString of hoLL LL_OPTIONSTR_EXPORTS_ALLOWED to sDummy_2
This should actually be LlSet... and LlGet... just like in the comment that’s also present. And it needs to be called earlier, here:
// Start the Report
//-> Insert the calls here!
Get LLPrintWithBoxStart of hoLL iProjectType sFile iDest LL_BOXTYPE_EMPTYABORT hWnd "Printing Records" to iRet
Can you double-check?
