vncViewer 1.2.4.0 ABORT on CHAT

Postby splintercode » 2020-02-13 11:30

The CHAT function on release 1.2.4.0 cause the vncviewer to abort!

I have started from the latest source dated 10 february 21:09:16 from cyberfox123 - internal update projectfiles for new signing.

Compiled with vstudio 2017.

When I try to use CHAT, VncViewer go in abort.

Debugging, the code stop on the end of the TextChar:DoDialog

int TextChat::DoDialog()
{
return DialogBoxParam(pApp->m_instance, DIALOG_MAKEINTRESOURCE(IDD_TEXTCHAT_DLG),
NULL, (DLGPROC) TextChatDlgProc, (LONG_PTR) this);
}

The exception say:

Exception thrown at 0x77C2815A (ntdll.dll) in vncviewer.exe: 0xC0000005: access violation while reading the path 0xFEFEFEAE.

I have no problem during the compilation, so I think that my development environment is ok.

Thank you.

Hard to tell, you should check the callstack.
Possible something goes wrong during initialization, but nit reoeatable on test pc.

Code: Select all
BOOL CALLBACK TextChat::TextChatDlgProc(  HWND hWnd,  UINT uMsg,  WPARAM wParam, LPARAM lParam )
{
    TextChat *_this = helper::SafeGetWindowUserData<TextChat>(hWnd);

   switch (uMsg)
   {

   case WM_INITDIALOG:
