Hello everyone, I am currently working with TTreeViewCtrl and implementing the HitTest function. However, I have noticed a potential issue regarding how we pass the TTvHitTestInfo structure to SendMessage. Here are two different implementations: 1️⃣ Implementation A (Correct?) //OWLNext 6.44 inline HTREEITEM TTreeViewCtrl::HitTest(TTvHitTestInfo* info) { return reinterpret_cast<HTREEITEM>(SendMessage(TVM_HITTEST, 0, TParam2(info))); } 2️⃣ Implementation B (Incorrect?) //OWLNext 7.16 inline HTREEITEM...

In OWLNext 6.44 it was: //listviewctrl.h bool TListViewCtrl::SetItemState(int index, uint state, uint mask) //listviewctrl.cpp bool TListViewCtrl::SetItemState(int index, uint state, uint mask) { LVITEM item; item.state = state; item.stateMask = mask; return ToBool(SendMessage(LVM_SETITEMSTATE, index, TParam2(&item))); } In OWLNext 7 it is: //listviewctrl.h auto TListViewCtrl::SetItemState(int index, TLvItem::TListState state, uint mask) -> bool //listviewctrl.cpp auto TListViewCtrl::SetItemState(int...

Hii @Vidar Hasfjord , While Investigation i found that in TLvItem class in listviewctrl.h file the TMaskFlag value is changed . (Refer below code) This is the reason my TLvItem is not inserted Properly in InsertItem(); in OWLNext 7: class _OWLCLASS TLvItem : public LVITEM { public: enum TMaskFlag { lvifAll = 0xFFFFFFFF }; in OWLNext 6: #if !defined(LVCF_ALL) # define LVCF_ALL (LVCF_FMT|LVCF_SUBITEM|LVCF_TEXT|LVCF_WIDTH) #endif #if !defined(LVIF_ALL) # define LVIF_ALL (LVIF_TEXT|LVIF_IMAGE|LVIF_PARAM|LVIF_STATE)...

we can also use this Solution : #ifdef _WIN64 return *(TUnknown*)((char*)this-(long long)(&((TUnknown*)0)->I)); #else return *(TUnknown*)((char*)this-(int)(&((TUnknown*)0)->I)); #endif Thank You !

Hii while upgrading project to cpp 17 from cpp14 , getting multiple errors for byte ambiguous symbol? is there any way to solve it . Support for OWLNext 7.For that, we first need to upgrade the C++ standard to C++17.While upgrading, I encountered a lot of errors related to byte types. Error C2872 'byte': ambiguous symbol i think the reason is there are multiple byte types are defined like :- but when i explicitly define (scope) like this std::byte then issue is fixed but in most of the cases i need...

Hii, I am reaching out to inquire about the upgrade process from OWLNext 6 to OWLNext 7. Specifically, I would like to understand the following: What are the key differences between OWLNext 6 and OWLNext 7? I am particularly interested in any new features or improvements that may impact our usage. What changes do we need to implement during the upgrade? Are there specific steps we should follow to ensure a smooth transition? Are there any additional considerations or resources you recommend for this...

Hi there! In my desktop application developed in C++, when I use Ctrl + X, I get a message beep, but I don’t want that beep. Additionally, when I use Ctrl + Shift + X, my dialog opens, and I again hear the message beep. I want to suppress or disable the message beep. How can I do this?

Hello Support Team, I need help with installing and setting up OWLNext 7. I attempted to install OWLNext using the OWLMaker.exe and created a new empty C++ project in Visual Studio 2022. However, I am unable to create an application because I believe I haven’t properly configured OWL with the project properties (such as include directories and additional directories). Could someone please provide guidance on how to correctly configure OWL with a new project in Visual Studio 2022? Thank you for your...
