WindowsMediaPlaye C++ WInform reference file error

Question

Friends.

I developed an application to play mp3 files in C# and it's working perfectly. I converted this application to C++ Winforms. When running, I don't have any errors, except when I click on a song name to play. I've included all WindowsMediaPlayer references. When clicking on the name of the song to play, it gives the following error:

System.IO.FileNotFoundException: Could not load file or assembly 'Interop.WMPLib.1.0, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null' or one of its dependencies. The system cannot find the specified file.

File name: 'Interop.WMPLib.1.0, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null'

The file mentioned above is found in the solution explorer list.

Does anyone have any idea what it could be?

Answer 1

It works for me if I copy

AxInterop.WMPLib.1.0.dll

Interop.WMPLib.1.0.dll

into the .exe folder

Then I can create the WMP control by code :

			AxWMPLib::AxWindowsMediaPlayer^ musica = gcnew AxWMPLib::AxWindowsMediaPlayer();
			musica->Size = System::Drawing::Size(400, 400);
			musica->Location = System::Drawing::Point(300, 10);			
			this->Controls->Add(musica);
			musica->URL = "E:\\01. IMANY - Don't Be so Shy (Filatov & Karas Remix).mp3";
			musica->Ctlcontrols->play();

Hi José Carlos Souza,

The problem should be in the file path, I suggest you add AxInterop.WMPLib.dll and Interop.WMPLib.dll to your project folder.

Also, this document is worth your reference.

Hi Yujian,

Did not work. The program itself created a folder called Interop with the files you mentioned and others. These files are also in the Windows\System32 folder. But still having problems. Even including the WindowsMediaPlayer control doesn't work. It gives the same error. Interesting that in C# everything works.
