Djg.DoModal();

if (Djg.DoModal()!=IDOK) return;

m_nLineWidth=Djg.m_nLineWidth; m_red=Djg.m_red; m_green=Djg.m_green; m_blue=Djg.m_blue; } （4）、存储和打开线数据的功能：主要通过菜单项弹出对话框来确定，其主要函数在视图类中表示时为OnSave()和OnOpen()，其具体实现为： void CMyView::OnSave() {

// TODO: Add your command handler code here CFileDat filedat;

if (filedat.DoModal()!=IDOK) return;

int size=Save.size();

ofstream OFile(filedat.m_File,ios_base::binary); OFile.write((char*)&size,4); for (int j=0;j<Save.size();j++) { //this->Getting=Save[j]; OFile.write((char*)&Save[j],sizeof(CGetting)); }

OFile.close(); }

void CMyView::OnOpen() {

// TODO: Add your command handler code here CFileDat filedat1;

if (filedat1.DoModal()!=IDOK) return; int size;

ifstream IFile(filedat1.m_File,ios_base::binary); IFile.read((char*)&size,4); Save.clear();

for (int k=0;k<size;k++) { IFile.read((char*)&Getting,sizeof(CGetting)); Save.push_back(this->Getting); }

IFile.close();
