[問題] VC++2008的backgroundWorker
遇到的問題： (題意請描述清楚)
我想用練習使用backgroundWorker
我把想用子thread做的事情寫在DoWork裡
然後在button的click裡叫它run
但是它不理我
一點反應都沒有 毫無動靜 囧
是因為沒加please不夠禮貌嗎......
自婊好爛的梗 Orz"
開發平台： (例: VC++ or gcc/g++ or Dev-C++, Windows or Linux)
VC++ 2008
有問題的code： (請善用置底文標色功能)
// button1 for calling thread run
private: System::Void button1_Click(System::Object^ sender,
System::EventArgs^ e) {
backgroundWorker1->RunWorkerAsync();
}
// backgroundWorker
private: System::Void backgroundWorker1_DoWork(System::Object^ sender,
System::ComponentModel::DoWorkEventArgs^ e) {
int i = 0;
while(1)
{
i ++;
label1->Text = i.ToString("e");
}
}
}
// button2 for calling thread canceled
private: System::Void button2_Click(System::Object^ sender,
System::EventArgs^ e) {
backgroundWorker1->CancelAsync();
}
=======================回應loveme大的分隔線=========================
loveme大, 請問您說的是這段嗎?
this->backgroundWorker1->DoWork += gcnew System::ComponentModel::\
DoWorkEventHandler(this,&Form1::backgroundWorker1_DoWork);
我是用win form designer拉元件進去
這段是designer自動生成的
補充說明：
先謝謝說明的高手了
感激 ^^"
