cli里控件的使用和c#有很大的相似性，先看看 openfiledialog ， backgroundworker， FolderBroswerDialog

1.把控件拖到界面上

2. 开始写按钮事件

//打开一个文本文件，并开始一个线程进行分析工作
openFileDialog1->Filter=gcnew String("文本文件|*.txt");
openFileDialog1->Title=gcnew String("选择用例");
openFileDialog1->Multiselect=true;
if(openFileDialog1->ShowDialog()==System::Windows::Forms::DialogResult::OK)
{
progressBar1->Location=System::Drawing::Point(11, 520);
myPercent=0;
this->backgroundWorker1->RunWorkerAsync();

}
else
{
ResetProgress();
}

3. backgroundworker 的使用

private: System::Void backgroundWorker1_DoWork(System::Object^ sender, System::ComponentModel::DoWorkEventArgs^ e) {

array<String^>^ NameArr=gcnew array<String^>(10000);
string msg;
NameArr=openFileDialog1->FileNames;
for(int i=0;i<NameArr->Length;i++)
{
int per=100/NameArr->Length;

if(openFileDialog1->FileName->Length>0)
{
if(isStep)
{
//不干了
if(iStop==0)
break;
AutoYongli(NameArr[i],per,i*per,backgroundWorker1,msg);
}
else
{
ReadYongli(NameArr[i],per,i*per,backgroundWorker1,msg);
}
}

}

//this->backgroundWorker1->ReportProgress(100);
ResetProgress();
}
private: System::Void backgroundWorker1_ProgressChanged(System::Object^ sender, System::ComponentModel::ProgressChangedEventArgs^ e) {
this->progressBar1->Value=e->ProgressPercentage;
}
private: System::Void backgroundWorker1_RunWorkerCompleted(System::Object^ sender, System::ComponentModel::RunWorkerCompletedEventArgs^ e) {
//MessageBox::Show("Work Completed");
}

3 选定一个文件夹，并赋值给路径box

fbd->ShowNewFolderButton=true;
if(fbd->ShowDialog()==System::Windows::Forms::DialogResult::OK)
{
txtLogPath->Text=fbd->SelectedPath;
txtLogPath->Text+="\\";
}
