[rdnzl-devel] Problems with Interop calls
by Eric 27 Dec '09

27 Dec '09

Hello everybody first off all i wanna thank you for this nice interface to the .Net-Framework. Now to my problem: I'm using RDNZL to control to ORC-Systems via .Net, my problem is that one OCR (tesseract) is working fine with it because it is possible to compile it with Microsoft Visual Studio(no problem at all). The other OCR-System ABBYY FineReader consits of DLL for which ABBYY provides an Interop-Assembly to communicate with it directly from the .Net-Framework. For controlling FineReader im using a C# Klasse (as an mediator in a DLL) which does futher action and intraktion with the OCR-System. If i use this Class direktly with a console-application compield in the .net-framework everything is fine. But if i use lisp and RDNZL to create an instance of the class and call a function of instance that calls _itself _a function of the ABBYY Interop-Assemble sometime the function call into the assembly don't came back. And if i start the process from Lispworks again everything works fine. Normally i would say it has nothing to do with RDNZL, but maybe it has some effects on the .Net-Framework which make it reacted different ??? So my question: Has someone experience with such a problem or does some know what i can do to find a workaround for this problem? -> When it stucks always the first call to the Interop-Assembly stucks, if this call don't stuck everything runs perfect. -> I also tried to call this Interop-Assembly directly with RDNZL with the same result, it sometimes stucks. Thanks a bunch for your help, Eric (If there is something unclear concerning my bad English and/or bad description i would be happy to describe it in detail) My System: - Win XP - LispWorks 5.1.1 Personal Edition - RDNZL 0.12.2. - Visual Studio 2008 Express Editions - .Net-Framework 3.5 Some Code: Unfortunately i can not provide an complete example or my full code, but here are at least some snippets. Also there happens nothing special, so i think the problem is somewhere else... and there is no exception coming back as if it is waiting or the call is not delivered. The function with starts the hole process in lisp: (defun OCR++FineReaderBildAuswerten (Speicherort bild sprache neuerSpeicherort ) (RDNZL:rdnzl-handler-case (let(dotNetList bilderAnzahl (ergebnis (list ) )) (OCR++FineReader-BilderPraeparieren (concatenate 'string Speicherort "\\" bild ) neuerSpeicherort) <<<---first Function to .Net see below (setq bilderAnzahl (- (OCR++FineReader-BilderAnzahl) 1)) (loop for n from 0 to bilderAnzahl do (OCR++FineReader-BilderOeffen n) (OCR++FineReader-InhaltAnalysieren ) (OCR++FineReader-InhaltAufbereiten sprache ) (OCR++FineReader-Speichern neuerSpeicherort bild :frz t :txt t) (setq dotNetList (OCR--FineReader-TextDatenStrukturLesen)) (setq ergebnis (cons (ORC--FineReader-erstelle-verschachtelterListe-Text dotNetList) ergebnis)) (OCR--FineReader-DokumentenAnalyseSaeubern)) (RDNZL:enable-rdnzl-syntax) (reverse ergebnis)) ( "System.Exception" (e) (print (RDNZL:invoke e "ToString") ) nil) )) =============================================== The first function which calls a function in the #Class: (defun OCR++FineReader-BildPraeparierenUndOeffnen(bild) (RDNZL:invoke fineref "bildPraeparierenUndOeffnen" bild ) ) =============================================== The function in the C# Class which calls a function of the Interop-Assembly: public Boolean bildPraeparierenUndOeffnen(String bildpfad) { Logger.logIT(this, " bildPraeparierenUndOeffnen: " + bildpfad, log); bildInformation = pEngine.PrepareAndOpenImage(bildpfad, bildBearbeitungsParameter, null, ref dokumentenInformation);*<<< here it stucks* Logger.logIT(this, " bildPraeparierenUndOeffnen: ende", log); return true; }

I should have thought of that myself... I made a new release with this change. Thanks and Happy Holidays, Edi.

[rdnzl-devel] New release 0.13.1 (Was: Could not load file or assembly error)
by Edi Weitz 22 Dec '09

22 Dec '09

I have now released a new version 0.13.1 which uses Load as a fallback (I had the same idea initially) and also exports do-rdnzl-collection. Raymond, thanks again for your help, but essentially this "fix" is against your original idea to catch errors early if an assembly isn't found, right? Do you have a better idea? (And good to hear about your experiences with RDNZL. I don't know of many users who deploy RDNZL "in earnest" - I'm certainly not one of them - but I'm always happy to hear about it.) Seth, thanks for the report. Cheers, Edi.

[rdnzl-devel] Could not load file or assembly error
by Seth Burleigh 15 Dec '09

15 Dec '09

Im attempting to get this to work on windows 7. I have .net 3.5 installed but when I try this. (defpackage :rdnzl-test (:use :cl :rdnzl)) (in-package :rdnzl-test) (enable-rdnzl-syntax) (import-types "System.Windows.Forms" "MessageBox" "MessageBoxButtons" "DialogResult") I get the error .NET error (System.IO.FileNotFoundException): Could not load file or assembly 'System.Windows.Forms' or one of its dependencies. The system cannot find the file specified. Im pretty new to all of this, though im guessing this has something to do with setting environmental vars or something. But since you know the library I figure you'll probably know the solution. Looking forward to getting this to work! Thanks!
