MFC中怎么设置文件过滤器？

[cau228charm]

默认情况下，打开文件时，显示所有文件（*.*），我现在想只让他显示*.bmp文件。应该怎么设。谢谢大家。。。。。。

[fmjk525283]

//选择打开文件夹
CFileDialog dlg(TRUE,"*.pct",NULL,OFN_HIDEREADONLY|OFN_OVERWRITEPROMPT,
"工艺卡片模板(*.pct)|*.pct|");

只打开.pct文件

[fmjk525283]

pct换成bmp就行

[sunraiing9]

CFileDialog dlg(FALSE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
_T("UC3D Mesh File(*.xml)|*.xml|;UC3D Binary Mesh File(*.bin)|*.bin|"),this);

看看我这个写法你就知道了 呵呵

不对啊，我的操作没有涉及到通用窗口的操作

quote:我的操作没有涉及到通用窗口的操作

难道你自己自定义一个打开文件对话框？

[cau228charm]

我直接用的mfc框架直接生成的阿 只是重写了OnOpenDocument函数
BOOL CEdgeContourDoc::OnOpenDocument(LPCTSTR lpszPathName)
{
CFile file; //定义文件对象，CFile是MFC类库中所有文件类的基类
CFileException fe; //定义文件异常对象，主要用来捕捉找不到指定文件的情况
。。。。。。。
这样的话
CFileDialog dlg(FALSE,NULL,NULL,OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
_T("UC3D Mesh File(*.xml)|*.xml|;UC3D Binary Mesh File(*.bin)|*.bin|"),this);
这些代码可以在那个文件里找到

[clever101]

explicit CFileDialog(
BOOL bOpenFileDialog,
LPCTSTR lpszDefExt = NULL,
LPCTSTR lpszFileName = NULL,
DWORD dwFlags = OFN_HIDEREADONLY | OFN_OVERWRITEPROMPT,
LPCTSTR lpszFilter = NULL,
CWnd* pParentWnd = NULL,
DWORD dwSize = 0
);
Parameters
bOpenFileDialog
Set to TRUE to construct a File Open dialog box or FALSE to construct a File Save As dialog box.
lpszDefExt
The default filename extension. If the user does not include an extension in the Filename edit box, the extension specified by lpszDefExt is automatically appended to the filename. If this parameter is NULL, no file extension is appended.
lpszFileName
The initial filename that appears in the filename edit box. If NULL, no filename initially appears.
dwFlags
A combination of one or more flags that allow you to customize the dialog box. For a description of these flags, see the OPENFILENAME structure in the Platform SDK. If you modify the m_ofn.Flags structure member, use a bitwise-OR operator in your changes to keep the default behavior intact.
lpszFilter
A series of string pairs that specify filters you can apply to the file. If you specify file filters, only selected files will appear in the Files list box. See the Remarks section for more information on how to work with file filters.
pParentWnd
A pointer to the file dialog-box object's parent or owner window.
dwSize
The size of the OPENFILENAME structure. This value is dependent on the operating system version, so MFC can determine the appropriate kind of dialog to create (for example, new Windows 2000 dialogs as opposed to NT4 dialogs).


lpszFilter 这个就是文件过滤器，msdn上的一个例子是
static char BASED_CODE szFilter[] = "Chart Files (*.xlc)|*.xlc|Worksheet Files (*.xls)|*.xls|Data Files (*.xlc;*.xls)|*.xlc; *.xls|All Files (*.*)|*.*||";

你对应参考一下吧

[hurryboylqs]

\0作为分割，\0\0作为结尾

我也有这个问题，在stringtable里可以解决，但是框架会报错

在stringtable里面,我想一次让两种或以上的格式显示,应该怎么做??
