I am trying to add a hyperlink that will direct a user of the application to a website. I see that MFC has a built in "MFC Link Control". In the dialog-editor. My hyperlinks look to work correctly.
When I debug my program, the links instead turn into buttons.
Is there a way to add non-button hyperlinks?
Thanks.
CButton is the natural base class of CMFCLinkCtrl. If it misses certain key properies, CMFCLinkCtrl will revert back to a CButton. My bet is on the URL. Try this:
CMFCLinkCtrl m_btnLink; // <-- associate with your control!
...
BOOL CTestDlg::OnInitDialog()
{
...
m_btnLink.SetURL(_T("http://www.example.com"));
m_btnLink.SetTooltip(_T("Link to my site"));
m_btnLink.SizeToContent();
...
}
Drag SysLink from Toolbox to your dialog box. Double click it and add this line to void function:
ShellExecute(
NULL, // or your can use GetSafeHwnd()
L"open",
L"http://stackoverflow.com/a/29181060/4057688",
NULL,
NULL,
SW_SHOWNORMAL
);

I am using VS2008.
I have MFC dialog based application with split button control.
I want to display a list box on the BCN_DROPDOWN event of split button control. I dont know how to achieve it?
Reference to the documentation of the CSplitButton class: https://msdn.microsoft.com/en-us/library/bb514109.aspx
If you want to change default behaviour then use the override:
BEGIN_MESSAGE_MAP(CMySplitButton,
CSplitButton)
ON_NOTIFY_REFLECT(BCN_DROPDOWN, &CMySplitButton::OnDropDown)
END_MESSAGE_MAP()
(...)
afx_msg void OnDropDown(NMHDR* pNMHDR, LRESULT* pResult);
You can in this function show your listbox or whatever you like.
If the listbox you refer to the actual submenu (3) as shown in the documentation, then add a menu: https://msdn.microsoft.com/en-us/library/4b6tafew.aspx and set the resource ID for that menu into SetDropDownMenu() function
void SetDropDownMenu(
UINT nMenuId,
UINT nSubMenuId);
Good luck :)
You must add your menu into a resource.
Ex:IDR_MENU_BUTTON_ANY
Declare some Resource symbols for submenu. It will change *.rc and resource.h.
Your resource will look like:
IDR_MENU_BUTTON_ANY
BEGIN
POPUP "SampleMenu"
BEGIN
MENUITEM "Sub1", ID_SUB_MENU_1
MENUITEM "Sub2", ID_SUB_MENU_2
END
END
When you initialize your dialog. You should insert some code as below:
//Your split button
CMFCSplitButton m_btnAny;
//Set dropdown menu
m_btnAny.SetDropDownMenu(IDR_MENU_BUTTON_ANY, 0);
More, I found the following link. The author provided an example. It may help you.

I'm using some Windows Forms Control Library elements in my app.
My question is:
How to perform button click event which this element comes from Windows Forms Control Library?
So, I can get *library* textbox value in ProgramDlg.cpp file like this:
void CMFCApplication1Dlg::OnBnClickedButton1()
{
// TODO: Add your control notification handler code here
AfxMessageBox(CString(m_ctrl1.GetControl()->textBox1->Text));
// m_ctrl1.GetControl()->button1->Click();
// how can I write this above line to perform click event?
}
I defined m_ctrl1 in ProgramDlg.h:
// ....
public:
CMFCApplication1Dlg(CWnd* pParent = NULL); // standard constructor
// Data member for the .NET User Control:
CWinFormsControl<WindowsFormsControlLibrary1::UserControl1> m_ctrl1;
// ....
p.s sorry for my bad english.
Thanks.
I solved my problem by visiting this link.

I am building a textEdit application with MFC. Is there a way to create a hyperlink automatically when a user write web address? It's like when you write a web address "www.google.com" the application detects web address and create a hyperlink right away. I have searched documents that explains about this, but couldn't find it..
and i couldn't make it..
i already have made notepad but i couldn't add the function of hyperlink on the notepad.
the following sentences are functions of hyperlink.
Clicking the text needs to open a browser window to the location specified by the text.
The cursor needs to change from the standard arrow cursor to a pointing index finger when it moves over the control.
The text in the control needs to be underlined when the cursor moves over the control.
A hyperlink control needs to display text in a different color—black just won't do.
The features that I added are:
5.A hyperlink control once visited needs to change color.
6.The hyperlink control should be accessible from the keyboard.
7.It should install some kind of hooks to allow the programmer to perform some actions when the control has the focus or when the cursor is hovering over the control.
Among the functions, What I mostly want to complete is the first one.
If I click a Hyperlink text, it should be linked to a browser window on the Internet.
Please answer and help me. Thanks.
Just use a CRichEditCtrl control (remember to call AfxInitRichEdit2 in your InitInstance). Call SetAutoURLDetect. Done.
Unfortunately this is not enough to make it work. It will display text that resembles URL as blue underlined but it will not invoke the link.
This will have to be handled by additional code. This will set needed event mask:
long lMask = m_RichEditCtrl.GetEventMask();
m_RichEditCtrl.SetEventMask(lMask | ENM_LINK);
m_RichEditCtrl.SetAutoURLDetect();
Also reflected EN_LINK will has to be handled to follow the link. For example:
void CHyperLinkInEditView::OnEnLink(NMHDR *pNMHDR, LRESULT *pResult)
{
ENLINK *p_Link = reinterpret_cast<ENLINK *>(pNMHDR);
if(p_Link && p_Link->msg == WM_LBUTTONDOWN)
{
//int iRange = m_RichEditCtrl.GetTextRange(p_enLinkInfo->chrg.cpMin, p_enLinkInfo->chrg.cpMax);
m_RichEditCtrl.SetSel(p_Link->chrg);
CString szLinkString = m_RichEditCtrl.GetSelText ();
ShellExecute(m_hWnd, L"Open", szLinkString, NULL, NULL, SW_MAXIMIZE);
}
*pResult = 0;
}
All of the above will solve requirement 1, 2, 3 (partially –text is underlined always), and 4.
I do not quite understand 5, 6 and 7.
Could you elaborate?
I've created a read-only edit box in an MFC dialog box. I'm trying to have it so a user clicks in the edit box, which is read-only, it opens a file dialog, and then puts this value into the text box using UpdateData. I'm catching the ON_EN_SETFOCUS message but pressing OK on the file dialog respawns it, so I get caught in an infinite loop.
UpdateData(TRUE);
CFileDialog fileDialog(TRUE,NULL, NULL,OFN_HIDEREADONLY|OFN_FILEMUSTEXIST, _T("Text Files(*.txt)|*.txt||"));
if( fileDialog.DoModal() == IDOK )
{
configFile=fileDialog.GetPathName(); //Note to self, this includes filename, getPathName includes filename and path.
}
else
{
return;
}
UpdateData(FALSE);
If you've got any ideas on how this should be done, I would be very grateful.
Alright Mr. Lister I guess I'll add an answer.
First off I would preface this with I would probably simply add a button name "..." to launch the file dialog to the right of the edit box for opening the file dialog as that's the simplest solution and what most windows users will expect.
Another option however is to extend an MFC control. When deciding to extend a control you want to pick one that mostly has the desired behavior and that has a virtual destructor which lends itself to being a subclass. Since you want button like behavior CButton may be a good choice.
Your class interface might look something like this:
class CPathButton : public CButton
{
public:
enum { ID /*= IDC_BUTTON1*/ };
const CString GetPath() const;
const CString GetFileName() const;
const CString GetDirectory() const;
const CString GetExtension() const;
// other useful methods for setting file filters etc
protected:
// add ON_CONTROL(BN_CLICKED, ID, &OnClick) or ON_BN_CLICKED(ID, &OnClick)
DECLARE_MESSAGE_MAP()
// CFileDialog fdlg.DoModal(), m_path = fdlg.GetPathName(), SetWindowText(fdlg.GetFileTitle()), etc
afx_msg void OnClick();
// additional message handlers etc
private:
CString m_path; // save full path for after dialog is closed
};
You can add as much or as little customization as you want depending on if the control will be created dynamically, via the resource file, or whatever. The basic idea being that you display the currently selected file name on the button while storing the full path for other uses as a member so the user doesn't need to see the clutter of a long path with nested directories.
If you don't like the way it looks by default you can override OnPaint and handle WM_PAINT messages and use a custom font, size, or add ellipsis for a long file title. You could also handle re-sizing the button to fit the file title by using text metrics and GetTextExtent to ensure the name fits or simply display a CToolTipCtrl when they hover the mouse over the button so they can see the full name. The CMFCButton from the MFC feature pack in VS2008+ has tool tip functionality built in so if you inherit from that instead of CButton displaying a tool tip would be as simple as calling SetTooltip(m_path)
If you want to get really fancy you could use some of the uxtheme API or new windows animation API.
You can override PreTranslateMessage() in your dialog class, and determine if the edit control was clicked that way:
CEdit m_CEditCtrl;
// ...
BOOL YourDialogClass::PreTranslateMessage(MSG *pMsg)
{
if((pMsg->wParam == VK_LBUTTON) && (m_CEditCtrl.m_hWnd == pMsg->hwnd))
{
// open your file dialog
return TRUE; // Return that the message was translated and doesn't need to be dispatched
}
return CDialog::PreTranslateMessage(pMsg);
}
Update: You can also (and it may be a better idea) to override your CEdit control's CWnd::PreTranslateMessage() function. This would require deriving a class from CEdit.
If you are using VS2008 SP1 or above, the easiest way to ask for a path is with CMFCEditBrowseCtrl. It displays an edit control with a button. The steps to use it are:
Change your edit control's class to CMFCEditBrowseCtrl
Call EnableFileBrowseButton to tell it that you want to browse for files, not folders (you can set a filter and default extension)
When the user clicks the button, a file dialog appears, and when you click OK in it, the selected path is written in the edit control.
Building a file open dialog replacement. Much of it works now, but I would like to generate the view-mode drop-down for the toolbar directly from the shell view object.
Looking at IShellView2, I can see IShellView2::GetView() will give me the FOLDERVIEWMODE's supported. However, that doesn't give me the names of these modes, nor format that popup menu for me, nor immediately give me a way to actually set one of those modes (it would appear it is necessary to destroy the shell view window and create a replacement one for the current folder and specify the new FOLDERVIEWMODE desired... yeesh).
At any rate, if one right clicks on an IShellView window, one gets a context menu, the first submenu of which is exactly what I want to place in my drop-down toolbar button (ie. the "view" fly-out menu (e.g. Small Icons, Medium Icons, etc.)).
It seems like there ought to be a way to grab that submenu directly from the IShellView, rather than having to hardcode my values (and that way, if a given instance of IShellView supports extra view modes, they'd be there. Similarly, those which should be disabled would be, since it would all be under the IShellView's control).
I have read Raymond Chen's excellent How to host an IContextMenu. Unfortunately, that just gives me a very simplistic context menu - the one for the folder itself, or for a file in a given folder, but NOT the context menu for the IShellView's shell view window (from which I might obtain the view fly-out).
I have tried the following, based on Chen's article:
CComQIPtr<IContextMenu> pcm(m_shell_view); // <<-- FAIL resulting pointer is NULL <<<
// create a blank menu
CMenu menu;
if (!menu.CreatePopupMenu())
throw CContextException("Unable to create an empty menu in which to store the context menu: ");
// obtain the full popup menu we need
if (FAILED(m_hresult = pcm->QueryContextMenu(menu, 0, SCRATCH_QCM_FIRST, SCRATCH_QCM_LAST, CMF_NORMAL)))
throw CLabeledException("Unable to query the context menu for the current folder");
// display the menu to the user
// menu.getsubmenu
::TrackPopupMenu(menu, ::GetSystemMetrics(SM_MENUDROPALIGNMENT)|TPM_TOPALIGN|TPM_LEFTBUTTON, pt.x, pt.y, 0, m_shell_view_hwnd, NULL);
Unfortunately, the attempt to query the m_shell_view (which is an IShellView*) for its IContextMenu interface fails. This "works":
// retrieve our current folder's PIDL
PidlUtils::Pidl pidl(m_folder);
// get the context menu for the current folder
CComPtr<IContextMenu> pcm;
if (FAILED(m_hresult = GetUIObjectOf(m_owner->m_hWnd, pidl, IID_PPV_ARGS(&pcm))))
throw CLabeledException("Unable to obtain the PIDL for the current folder");
But here I get only a very few options in the context menu (Open, Explore, ...). Not the detailed context menu that I get if I simply right click on the shell view itself.
I'm out of ideas as to how to proceed. Help?! ;)
Try IShellView::GetItemObject with SVGIO_BACKGROUND as uItem to get a IContextMenu on the view object : http://msdn.microsoft.com/en-us/library/bb774832%28VS.85%29.aspx
There is the SHCreateDefaultContextMenu (Vista an up) that may be of help. Bjarke Viksoe website contains great info as well.
SVGIO_BACKGROUND will get you the background context menu of the shell view. You may need to call repeatedly pShellView->SelectItem for each PIDL you may have, then do the GetUIObjectOf call (then QI for IContextMenu, create a menu, call IContextMenu(3)::QueryContextMenu and finally display it with TrackPopupMenu).
