Stap 3: Microsoft Visual Studio C# applicatie
Nu is het tijd voor het opstarten van Microsoft Visual Studio. We beginnen met het maken van een C# windows-formuliertoepassing. Ik beginnen door het creëren van de UI. Het gaat hierbij om 5 labels, 1 RTF-vak en 2 knoppen. Deze kunnen worden toegevoegd aan het formulier met behulp van de werkset aan de linker kant van het scherm.
Zodra u de bovenstaande items hebt toegevoegd, kunt u dubbelklikken op de bovenste rand van uw toepassing. Dit zal omhoog het C#-codevenster achter uw programma brengen. In de code aangesloten en hieronder ik heb geprobeerd om veel van het commentaar, het vrij gemakkelijk te volgen moet zijn. Zo niet ik heb een "officiële" versie van het programma en de Visual Studio-projectbestand bijgevoegd.
U kunt de COM-poort op wat uw robot is op. Mijn robot was op COM5.
