I recently write a simple test app(which is a winUI3 app (C )), and I want to put some message to console, in order to help me with debugging.
I used "console.WriteLine" but get this error: 'Console': is not a class or namespace.
I looked up in the Microsoft website, but it couldn't work either.(I could not include "system" in my .cpp file)
the code is following:
using namespace system; // would get this Error:'system': a namespace with this name does not exist
using namespace winrt::Windows::UI::Popups;
using namespace std;
using namespace winrt;
using namespace Windows::Foundation;
using namespace Microsoft::UI::Xaml;
namespace winrt::SampleApp::implementation
{
LoginPage::LoginPage()
{
InitializeComponent();
Console::WriteLine("hello!");
}
I have looked up following links, but got no luck. this is for c#
I just want a way to show the messages to help me debug.
Console is a good way, and I also tried OutputDebugString but no message output in the output window. Where did I do wrongly?
Can anyone help me? Thanks a lot! Any suggestion is appreciated!
CodePudding user response:
Have you tried 'cout << "Value of a is " << a;'
CodePudding user response:
Why cannot use "console.WriteLine" in winUI3 app (C )?
Because System.Console
is a .NET API.
If you want to print something to the debug output window in a WinUI 3 C app you could use the OutputDebugStringA
function:
LoginPage::LoginPage()
{
InitializeComponent();
OutputDebugStringA("hello1!\n");
}
