//以上我的查找文件的时候,添加的一个进度条,查找文件没有问题...
我发现的是,在这里的话,进度条处理的方法:
//Management the ProgressBar form.
void MngProgressBarForm() {
try {
MethodInvoker proBarFormInvo = ProgressBarFormShow;
this.BeginInvoke(proBarFormInvo);
Thread.Sleep(1000); //sleep for a while to show the window.
bool bIncProBar = false; //determine whether increase the ProgressBar successfully.
do {
Thread.Sleep(5); //sleep a while each time trying to increase the ProgressBar value.
bIncProBar = (bool)this.Invoke(_incProBar, new object[] { 2 });
} while(bIncProBar);
}
catch(System.Exception ex) {
MessageBox.Show(ex.Message);
}
}
//中, Thread.Sleep(1000); //sleep for a while to show the window.如果改成线程暂停时间较短的话,进度条窗口不前进...什么意思哈...
