hi! my application is handling the communication with a hardware device. since the app should not wait for answers from the hardware, i use threads for talking and listening to the device. to make things more complicated, i have to make sure to only talk to the device when there is no answer pending...

i have a similar problem. i built wxwidgets 2.9.4 with the default options in windows. in the file C:\wxWidgets-2.9.4_vc11\include\wx\msw\setup.h it sais #define wxUSE_DATEPICKCTRL 1 // wxDatePickerCtrl but still i cannot use wxDatePickerCtrl (unresolved external symbol): error LNK2019: Verweis auf ...

perfect, thanx!

hi, i use wxWidgets 2.9.1 und am trying to use wxCTB 0.9. i get these "unresolved external symbol" errors: 1>wxctbd-0.9.lib(wxctb_lib_timer.obj) : error LNK2019: Verweis auf nicht aufgelöstes externes Symbol "[email protected]" in Funktion ""public: int __thiscall timer::stop(void)" ([email protected]...

ok, i will disable the part of my app that needs this dll in 64bit environments.
thanx!

ok, i just could load "wxmsw291ud_adv_vc_custom.dll" with the code above, so what could be wrong with the dlls that i cannot load? edit: when i open my dll with dependecy walker, there are three more dll errors than with wxmsw291ud_adv_vc_custom.dll: kbas6.dll, khdw6.dll and kioa6.dll are missing. i...

doublemax, thanx for your idea. the path is correct. when i change my code to #include "mnml_app.h" #include <wx/dynlib.h> #include <wx/stdpaths.h> #include <wx/file.h> bool App::OnInit() { wxString path = wxStandardPaths::Get().GetExecutablePath().BeforeLast('\\') + _("\\myDll.dll"); if(wxFile::Exi...

hi, in my application i had some code that used to work fine. some months ago i deactivated it with a comment and now that i want to ude it again it does not work anymore. in the meantime i switched from wxWidgets 2.8.12 to 2.9.1 and from xp to win7, but i already tested in the old configuration and...

thanx doublemax! while i was trying to compile a static linking version of wxwidgets, i came across a hint in http://wiki.wxwidgets.org/Microsoft_Visual_C%2B%2B_Guide#Version_information saying that wxWidgtes 2.8 does not yet support vs2010. i did not mention before that i was using wxwidgets 2.8.11...

thanx for your reply! i am not sure if i understand. in visual studio i changed c++->code generation->runtime library from \MDd to \MTd for the exe and all my dlls, but still i get the "no symbols loaded for wxmsw28ud_core_vc_custom.dll" entries in my call stack when i pause the exe. is there anythi...

has anyone any information about this?

here is the surrounding code: void PlotterBaseCont::doStepDirectly( int start, int stop ){ wxMemoryDC *sigMdc = new wxMemoryDC(); // <- the error occurs here if(sigMdc->IsOk()){ allBtmpCritSec->Enter(); sigMdc->SelectObject(*getAllBitmap()); doStep(start, stop, *sigMdc); sigMdc->SelectObject(wxNullB...

windbg shows me the line wxMemoryDC *sigMdc = new wxMemoryDC(); , so I guess the error occurs somewhere else and it just shows here. maybe there is a memory leak and wxMemoryDC is the place where it shows because it allocates a lot of memory?!? if the error should occur someplace else, how can i fin...

hi everyone, i am hunting a strange error that seems to be wx related, at least is sais something about wxPrintPaperType. does anyone have an idea about this? ======================================= VERIFIER STOP 00000002: pid 0x79C: Access violation exception. 11932FD4 : Invalid address causing the...

thank you for your answer! thing is, it sais in the docs for wxArray::Sort wxSortedArray doesn't have this function because it is always sorted. so, this is kinda awkward, don´t you think? how can one keep it sorted then? probably not using a wxSortedArray at all? i cannot imagine that i am the firs...
