Hello,
I'm creating Win32 application with XAML island. I want to allow drag-and-drop of UI element. Below is the code to give an idea of what I'm trying to do. Basically, I want to drag TextBlock and drop on Canvas.
This is working as expected for normal launch, but if I launch in administrative mode, it's crashing when I try to drag the TextBlock.
Can you please help me understand the reason and possible fix to this issue?
TextBlock* tb1, * tb2;
Canvas* z1;
StackPanel* xc;
void DragStarting([[maybe_unused]] UIElement const& pSender, DragStartingEventArgs const& pArgs) noexcept
{
pArgs.Data().SetText(pSender.try_as<FrameworkElement>().Name());
}
void DragOver(const winrt::Windows::Foundation::IInspectable pSender, DragEventArgs const& pArgs) noexcept
{
pArgs.AcceptedOperation(DataPackageOperation::Move);
}
void Drop(const winrt::Windows::Foundation::IInspectable pSender, DragEventArgs const& pArgs) noexcept
{
uint32_t index;
if (pArgs.DataView().Contains(StandardDataFormats::Text())) {
if ((*xc).Children().IndexOf(*tb1, index)) {
(*xc).Children().RemoveAt(index);
(*z1).Children().Append(*tb1);
}
}
}
int CALLBACK WinMain(_In_ HINSTANCE hInstance, _In_opt_ HINSTANCE hPrevInstance, _In_ LPSTR lpCmdLine, _In_ int nCmdShow)
{
// ... create window and xaml island ...
// Add UI elements for drag and drop
Windows::UI::Xaml::Controls::StackPanel xamlContainer;
Canvas zone;
Windows::UI::Xaml::Controls::TextBlock textblock;
Windows::UI::Xaml::Controls::TextBlock textblock1;
tb1 = &textblock;
tb2 = &textblock1;
z1 = &zone;
xc = &xamlContainer;
textblock.Text(L"Drag this...");
textblock.Name(L"textblock");
textblock.CanDrag(true);
textblock.DragStarting(DragStarting);
xamlContainer.Children().Append(textblock);
textblock1.Text(L"Drop here...");
textblock.Name(L"textblock1");
zone.Children().Append(textblock1);
zone.Margin({ 100, 100, 100, 100 });
zone.AllowDrop(true);
zone.DragOver(DragOver);
zone.Drop(Drop);
xamlContainer.Children().Append(zone);
// ... Message loop ...
return 0;
}
Thanks.
Could you please tell us what is the error you got when the application crash?
@Jeanine Zhang-MSFT There is no error box or anything, it(process) is just dying.
I'm running .exe directly to open in admin mode. I'll check and let you know if we can launch with debugger in admin mode to get some logs.

Below are the logs when it's crashing, if it helps.

Access is denied is related to the permissions. Whether it crashes only when run as administrator? It's so weird. Whether have you tried testing with a different device?
Does your application have to run in admin mode?
@Jeanine Zhang-MSFT Sorry for the delay.
Yes, I tried with different devices (including Windows 10 and 11 both), facing same issue.
Our application SHOULD run in admin mode.
