프로그래밍을 잘 모르는 학생인데요 어쩌다보니 일을 맞게 되었습니다.
문제가 생기는 부분은아래에 적어분 코드 전문에서 위의 코드는 잘 돌아가는데 아래에서 발생하는 문제가
private void sportRCV(object sender, EventArgs e)
{
Device.DataEventArgs de = (Device.DataEventArgs)e;
NeuroSky.ThinkGear.DataRow[] tempDataRowArray = de.DataRowArray;
TGParser tgParser = new TGParser();
tgParser.Read(de.DataRowArray);
L = tgParser.ParsedData.Length;
double[] RawLD = new double[L];
float[] RawL = new float[L];
if (serialPort1.BytesToRead > 0) //데이터가 읽혀지면 출력
{
string valueStr = serialPort1.ReadLine();
string[] valueStrArray = valueStr.Split(',');
이쪽인데요
Device.DataEventArgs de = (Device.DataEventArgs)e;
이부분이 EventArgs 타입을 DataEventArgs로 캐스팅 할수 없다고 하면서 오류가 납니다.
DataEventArgs타입의 경우 회사에서 준 솔루션 파일에 포함되어있는 헤더파일 안에 정의되어있고요
콘솔파일로 돌릴때는 돌아가는데 그걸 윈도우 폼으로 바꾸려고 다른 팀원이 작업중이던 원도우폼에 조금씩 잘라 붙여가고 있었는데
저곳에서 캐스팅 할수 없다면서 오류가 나더라고요
콘솔에서는 잘 캐스팅 되면서 왜 저기서는 저러는지 답답해 죽겠습니다 ㅜㅜㅜ
코드 전문도 올리겠습니다.

여기까지가 윈도우폼으로 바꾸려는 중에 있는 코드입니다.
코드가 아직 완성도 아니라 뒤죽박죽인데요
콘솔프로그램 돌릴때는 멀쩡히 하던 캐스팅을 왜 못하는지 모르겠습니다. ㅜㅜㅜㅜ
