MFC SDI文件打开对话框 [英] MFC SDI File Open Dialog

问题描述

我创建了一个基于资源管理器样式的MFC SDI项目（它有一个包含树视图的左侧窗格，右边我希望打开文件的手窗格。



已经有一个打开文件对话框的文件打开菜单项。当用户从文件打开对话框中选择文件时，如何知道文件已被选中以及其名称和目录位置是什么？如何在我的代码中捕获它？



非常感谢。

解决方案

我编写任何MFC已经四年多了东西，但它是这样的：

 CString路径; 
  if （dlg.DoModal（）== IDOK）
 {
 path = dlg.GetPathName（）; 
} 

您可以使用CFileDialog :: DoModa（）函数的返回值。如果是IDOK，则用户选择文件并通过单击打开按钮关闭对话框，如果是IDCANCEL，则使用取消按钮或X按钮关闭对话框。

示例：

 CFileDialog FileDilog; 
 if（FileDialog.DoModal（）== IDOK）
 {
 //所选文件的完整路径。 
 CString strFilePath = FileDialog.GetPathName（）; 
} 

如果您想知道允许多个文件选择使用代码，

 if（FileDialog.DoModal（）== IDOK）
 {
 POSITION pos = FileDialog.GetStartPosition（）; 
 while（pos！= NULL）
 {
 CString strFilePath = FileDialog.GetNextPathName（pos）; 
 //处理文件
} 
}

只需覆盖应用程序基于CDocument的类中的虚拟OnFileOpen函数。

 虚拟 BOOL OnOpenDocument（LPCTSTR lpszPathName）; 

Hi,

I have created an MFC SDI project based on the explorer style (it has a left-hand pane containing a tree-view, and a right-hand pane into which I wish to open files).

There is already a file-open menu item which opens a file dialog. When the user selects a file from within the file-open dialog, how do I know that a file has been selected and what its name and directory location is? How do I capture this in my code?

Many thanks.

解决方案

It''s been more than four years since I wrote any MFC stuff, but it goes something like this:

CString path;
if (dlg.DoModal() == IDOK)
{
    path = dlg.GetPathName();
}

Hi You can use the Return value of CFileDialog::DoModa(), Function. If it is IDOK the user selected a file and closed the dialog by clicking on open button and if it is IDCANCEL the dialog was closed using cancel button or X button.
Example:

CFileDialog FileDilog;
if(FileDialog.DoModal() == IDOK)
{
      //Full path of selected file.
      CString strFilePath = FileDialog.GetPathName();
}

In case if you want to know allow multiple file selection Use The code,

if (FileDialog.DoModal() == IDOK)
{
  POSITION pos = FileDialog.GetStartPosition();
  while (pos != NULL)
  {
    CString strFilePath = FileDialog.GetNextPathName(pos);
    // Process the file
  }
}

Check MSDN for More info.

Just override the virtual OnFileOpen function in your application''s CDocument based class.

virtual BOOL OnOpenDocument(LPCTSTR lpszPathName);
