PseudoResources in Automation Plugin

Question

My company has published a small automation plugin for Photoshop using the Adobe Photoshop 5.0 SDK.  It currently works on my machine (Windows 2000) using Photoshop 7.<br /><br />I'm trying to modify the plugin so that it saves some data in the current document.  The docs say that Pseudo Resources are the way to do this.  Whenever I call addProc, I get no error, but countProc and getProc act as though I haven't added anything.  Can anyone clue me in to what I've left out / done wrong in the following incantation?....<br /><br /><pre><br />#include <PIUtilities.h><br /><br />class PSPseudoResource_t : public PIUSuitePointer<ResourceProcs> {<br />   public:<br />   PSPseudoResource_t(SPBasicSuite* inSPBasic);<br />};<br /><br />PSPseudoResource_t::PSPseudoResource_t(SPBasicSuite* inSPBasic = NULL) :<br />   PIUSuitePointer <ResourceProcs> (<br />      inSPBasic,<br />      kPIResourceSuite,<br />      kPIResourceSuiteVersion<br />   ) {<br />}<br /><br />PSPseudoResource_t sPSPseudoResource(NULL);<br /><br /> *snip*<br /><br />SPAPI SPErr ENTRYPOINT(const char* const caller, <br />   const char* const selector, const void* const data) {<br />   const char* optionalSuiteIDs [] = {<br />      kPSBasicActionControlSuite,<br />      kPSChannelPortsSuite,<br />      kPIResourceSuite,<br />      NULL<br />   };<br /><br />   // This C++ object takes care of all dispatching.<br />   static PIUDispatch* dispatcher = new PIUDispatch (<br />      (char**) &optionalSuiteIDs,<br />      ADMAboutID,<br />      PIUAPI_None,<br />      Plugin::sExecute,<br />      PIUAPI_None,<br />      PIUAPI_None,<br />      PIUAPI_None,<br />      PIUAPI_None<br />   );<br /><br /> *snip*<br /><br />   #define MY_RES_TYPE 0x61746164<br />   int ret = 0;<br />   Handle h = NULL;<br />   char prbuff[1024] = "some_text";<br />   SPBasicSuite *sbs = &*sSPBasic;<br />   if (sbs != NULL) {<br />      h = sPSHandle->New(256);<br />      GlobalLock(h);<br />      strcpy(*h, prbuff);<br />      GlobalUnlock(h);<br />      PSPseudoResource_t new_sPSPseudoResource(sbs);<br />      sPSPseudoResource = new_sPSPseudoResource;<br />      // Returns 0<br />      ret = new_sPSPseudoResource->countProc(MY_RES_TYPE);<br />      if (ret == 0) {<br />         // Returns 0<br />         ret = new_sPSPseudoResource->addProc(MY_RES_TYPE, h);<br />      }<br />      // Returns 0<br />      ret = new_sPSPseudoResource->countProc(MY_RES_TYPE);<br />      // Returns NULL<br />      h = new_sPSPseudoResource->getProc(MY_RES_TYPE, 1);<br />   }<br /><br />   *snip*<br />}<br /></pre>

Try making a filter plug-in and adding your resources there. Make the filter plug-in scriptable so you can call it from your automation plug-in.
