請問各位大大:
在C#中新增一個Button,主要功能是要清除所連結的資料庫裡面的內容
請問應該要怎麼寫呢??

另外,在下面的程式中,執行時在連結資料庫的時候似乎會有問題,請問大概是哪邊有問題呢?

謝謝各位大大的悉心解答~

private void Timer_Action_Tick(object sender, EventArgs e)

try

DataRow row = fpsdbDataSet.Tables[0].Rows[m_Pos];

axRemoteSetup.GetCam(i, "camtype", out(m_ANALOG));
axRemoteSetup.SetCam(i, "enable", row[5].ToString());
axRemoteSetup.SetNetworkService("rmapi", "monitor_framerate", row[6].ToString());
