  • Problems using wxWidgets (wxMSW) within multiple DLL instances

    Preface I'm developing VST-plugins which are DLL-based software modules and loaded by VST-supporting host applications. To open a VST-plugin the host applications loads the VST-DLL and calls an appropriate function of the plugin while providing a native window handle, which the plugin can use to draw it's GUI. I managed to port my original VSTGUI code to the wxWidgets-Framework and now all my plugins run under wxMSW and wxMac but I still have problems under wxMSW to find a correct way to open and close the plugins and I am not sure if this is a wxMSW-only issue. Problem If I use any VST-host application I can open and close multiple instances of one of my VST-plugins without any problems. As soon as I open another of my VST-plugins besides my first VST-plugin and then close all instances of my first VST-plugin the application crashes after a short amount of time within the wxEventHandlerr::ProcessEvent function telling me that the wxTheApp object isn't valid any longer during execution of wxTheApp-FilterEvent (see below). So it seems to be that the wxTheApp objects was deleted after closing all instances of the first plugin and is no longer available for the second plugin. bool wxEvtHandler::ProcessEvent(wxEvent& event) { // allow the application to hook into event processing if ( wxTheApp ) { int rc = wxTheApp->FilterEvent(event); if ( rc != -1 ) { wxASSERT_MSG( rc == 1 || rc == 0, _T("unexpected wxApp::FilterEvent return value") ); return rc != 0; } //else: proceed normally } .... } Preconditions 1.) All my VST-plugins a dynamically linked against the C-Runtime and wxWidgets libraries. With regard to the wxWidgets forum this seemed to be the best way to run multiple instances of the software side by side. 2.) The DllMain of each VST-Plugin is defined as follows: // WXW #include "wx/app.h" #include "wx/defs.h" #include "wx/gdicmn.h" #include "wx/image.h" #ifdef __WXMSW__ #include <windows.h> #include "wx/msw/winundef.h" BOOL APIENTRY DllMain ( HANDLE hModule, DWORD ul_reason_for_call, LPVOID lpReserved ) { switch (ul_reason_for_call) { case DLL_PROCESS_ATTACH: { wxInitialize(); ::wxInitAllImageHandlers(); break; } case DLL_THREAD_ATTACH: break; case DLL_THREAD_DETACH: break; case DLL_PROCESS_DETACH: wxUninitialize(); break; } return TRUE; } #endif // __WXMSW__ class Application : public wxApp {}; IMPLEMENT_APP_NO_MAIN(Application) Question How can I prevent this behavior respectively how can I properly handle the wxTheApp object if I have multiple instances of different VST-plugins (DLL-modules), which are dynamically linked against the C-Runtime and wxWidgets libraries? Best reagards, Steffen

  • Changing Graphic Instance using ActionScript

    - by Luke Duddridge
    Hi, I was wondering if it is at all possible to change the "Graphic" used in a frame dynamically using actionscript. I was hoping to either change the image the Graphic is an instance of or change the Graphic I am using in the current frame. Cheers Addition: Could I have a layer for each Graphic and then using action script choose which layer shows?

  • Which is more Efficient HTML DOM or JQuery

    - by Quasar the space thing
    I am trying to add new Elements in an HTML page body by using document.createElement via Javascript, I am doing this with few if/else case and function callings. All is working fine. Recently I came to know that I can do this with JQuery, too. I have not done too much of coding yet so I was wondering which way is the best in terms of efficiency ? Using native DOM methods or using JQuery to add elements dynamically on the page?

From my searches on the web everything seem to be OK. Any idea?

  • Dynamic Attachment Size for Paperclip (Rails)

    - by CalebHC
    Is there anyway to have the validates_attachment_size except a dynamic file size limit? Here's an example: class Document < ActiveRecord::Base belongs_to :folder has_attached_file :document validates_attachment_size :document, :less_than => get_current_file_size_limit private def get_current_file_size_limit 10.megabytes # This will dynamically change end end I've tried this but I keep getting an error saying "unknown method". Lambdas and Procs don't work either. Has anyone ever tried this? Thanks

  • Access Controls in Silverlight DataGrid Column Header from Code

    - by fuzzyman
    We have custom headers in the Silverlight DataGrid using the ContentTemplate. We've got a button in the header and need to programmatically access the button to hook up the event. We're using IronPython, so we can't statically bind the event in the xaml (plus we use the grid for many different views - so we dynamically generate the xaml). How can we get access to controls inside a datagrid column header?

  • Query Results Not Expected

    - by E-Madd
    I've been a CF developer for 15 years and I've never run into anything this strange or frustrating. I've pulled my hair out for hours, googled, abstracted, simplified, prayed and done it all in reverse. Can you help me? A cffunction takes one string argument and from that string I build an array of "phrases" to run a query with, attempting to match a location name in my database. For example, the string "the republic of boulder" would produce the array: ["the","republic","of","boulder","the republic","the republic of","the republic of boulder","republic of","republic of boulder","of boulder"]. Another cffunction uses the aforementioned cffunction and runs a cfquery. A query based on the previously given example would be... select locationid, locationname, locationaliasname from vwLocationsWithAlias where LocationName in ('the','the republic','the republic of','republic','republic of','republic of boulder','of','of boulder','boulder') or LocationAliasName in ('the','the republic','the republic of','republic','republic of','republic of boulder','of','of boulder','boulder') This returns 2 records... locationid - locationname - locationalias 99 - 'Boulder' - 'the republic' 68 - 'Boulder' - NULL This is good. Works fine and dandy. HOWEVER... if the string is changed to "the republic", resulting in the phrases array ["the","republic","the republic"] which is then used to produce the query... select locationid, locationname, locationaliasname from vwLocationsWithAlias where LocationName in ('the','the republic','republic') or LocationAliasName in ('the','the republic','republic') This returns 0 records. Say what?! OK, just to make sure I'm not involuntarily HIGH I run that very same query in my SQL console against the same database in the cf datasource. 1 RECORD! locationid - locationname - locationalias 99 - 'Boulder' - 'the republic' I can even hard-code that sql within the same cffunction and get that one result, but never from the dynamically generated SQL. I can get my location phrases from another cffunction of a different name that returns hard-coded array values and those work, but never if the array is dynamically built. I've tried removing cfqueryparams, triple-checking my datatypes, datasource setups, etc., etc., etc. NO DICE WTF!? Is this an obscure bug? Am I losing my mind? I've tried everything I can think of and others (including Ray Camden) can think of. ColdFusion 8 (with all the latest hotfixes) SQL Server 2005 (with all the greatest service packs) Windows 2003 Server (with all the latest updates, service packs and nightly MS voodoo)

  • table cell and row borders different on each edge in C#

    - by tbischel
    I'm trying to dynamically generate a report in a table where the borders are different on each side of a cell or row, but can't figure out how. The TableRow, TableCell, and Table objects each have a BorderStyle property, but it seems to apply to the entire border rather than just one side. Can this be done without nesting tables? For my case, I'd like a solid border around the first two rows of a table (because the first row has a cell spanning two rows), and a solid border around each subsequent row.
