Hello, Im creating simple dialog for my 3DXI exporter, so i want specify some specific folders and Im trying to show DoMaxBrowseForFolder
INT_PTR CALLBACK ExportOptionsDlgProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch(message) {
case WM_COMMAND:
switch (LOWORD(wParam))
{
case IDC_BTN_MESH:
pathControl = IDC_PATH_MESH;
initPath = params.m_meshPath;
Interface13* imax = GetCOREInterface13();
imax->DoMaxBrowseForFolder(hWnd, _M(""), initPath);
//..
The dialog is showing, but buttons or other controls don`t work, Ive tried pass NULL or MaxhWnd as hWnd to DoMaxBrowseForFolder.
Ive checked in the debugger that the threads locks in NtPeekMessage, may be i have specify something?
Here im creating dialog:
if (!suppressPrompts && !DialogBoxParam(hInstance, MAKEINTRESOURCE(IDD_PANEL), pInterface->GetMAXHWnd(), ExportOptionsDlgProc, (LPARAM)(LPVOID)this))
return 1;
Is it OK that parent for FolderDialog also dialog?
MaxSDK 13.

I’ve tried a lot of things, but, unfortunately without success.
The exception still occur.
Here a code of FileDialog creation:
MSTR title = _M("Save as File"), _fname = _M(""), _path = _M("");
Interface13* imax = GetCOREInterface13();
FilterList filterList;
imax->DoMaxSaveAsDialog(imax->GetMAXHWnd(), title, _fname, _path, filterList));
In the samples the code is same, i don’t know why my isn’t work.
Here is exception:
Unhandled exception at 0x0000000140496249 in 3dsmax.exe: 0xC000041D: An unhandled exception was encountered during a user callback.
