Hi
Is there any way to get the pasted text in a dialog?
Any control in the dialog may have the focus.

You can read the contents of the clipboard with the GetClipboardData()[^] function, and write it to any control.

One of these days I'm going to think of a really clever signature.

Thanks
But I want to get the text when it's pasted.
I checked WM_PASTE but it is send to the control that has the focus not it's parent CWnd.
My dialog has some control of buttons, edit boxes, list control, ...
so it is posible that any of these controls has the focus (when something is paste)

how can get a disk number of a logical drive?

10-Nov-12 21:27

You need to subclass the controls[^] and capture the message that way.

What do you mean by "disk number"?

disk may have multiple logical drive.

so i want to know the selected logical drive related to which disk.

Check out these functions[^]. It's a while since I have done this but I'm afraid it is somewhat involved in terms of getting mutliple sets of information and matching the pieces together. Hey, if it wasn't Microsoft it wouldn't be fun.

Probably by writing a program; but without some more details of exactly what you are trying to do it is difficult to be more precise.

How to stop typing in CDateTimeCtrl in MFC

I have a CDateTimeCtrl on my dialog. Through this I can choose any date in given range from drop down. But currently user is also allowed to press numeric keys to set the date. Is there any way to stop user from typing in it. I want, he should only be able to select the date from drop-down and I don't want to disable the control.
I have checked the "AllowEdit" property but that is different thing. Currently it is set to false.

You may derive a class from CDateTimeCtrl() and add a WM_CHAR / OnChar() handler that does nothing or calls the base class handler for non-digit chars only.

I've just tested it. It does not effect keys pressed in the drop down calendar and still allows cursor keys and TAB in the edit control.

Thanks Jochen, you are right. That way it will work. But for such a small requirement, I don't want to do big changes D'Oh! | :doh:

and also I don't want to go for pretranslate message. Is there any way to handle WM_CHAR/OnChar events for the date control on the same dialog class?

Re: How to stop typing in CDateTimeCtrl in MFC

You are using MFC, so you don't need to handle PreTranslateMessage(). Just use the wizard to derive a class, use the message properties to add the WM_CHAR handler, and comment the line calling CDateTimeCtrl::OnChar(). Done with a few mouse clicks. All you need to type in using the keyboard is the name of the drived class, the comment chars, and replacing the CDateTimeCtrl by your class name in your code.

The edit control of CDateTimeCtrl is not accessible. So it can't be done in the dialog. Even when it would be possible: It is always better to perform such things in the control rather than in the dialog. So it must be done only once and not within every dialog that uses such a control.

Why new Image failed?

Re: Why new Image failed?

XML

<pre lang="c++">
        Image*  m_pImage;
    CString  strTempIMGPath = m_strCurrentImagePath;
    wchar_t szFile[256] = {0};

    char *pStr = strTempIMGPath.GetBuffer(0);
    int size = MultiByteToWideChar(GetACP(), 0, pStr, -1, NULL, 0);
    MultiByteToWideChar(GetACP(), 0, pStr, -1, szFile, size);
    strTempIMGPath.ReleaseBuffer();
    if (m_pImage != NULL)
    {
        delete m_pImage;
        m_pImage = NULL;
    }
<b> m_pImage = new Image(szFile, FALSE);</b>
    if(m_pImage->GetLastStatus() == Gdiplus::Status::Ok)
    {
...
    }

After this statement,m_pImage = new Image(szFile, FALSE)
the m_pImage is NULL, I do not know why create Image failed, after debug that I find that the szFile is a right PNG image file path.

The last code used in a CDialog form, I use the CDialog::DoModel() to show this dialog in the
CMyApp::InitInstance()
I do not know whether I use this class Image too early, or I need use some code to initialize the GDI+ library?

replace the first line with this:

C++

Image*  m_pImage = NULL;

Otherwise, m_pImage is not NULL, and you are trying to delete uninitialised pointer, leadding to memory corruption

// Used for GDI+ initialisation.
ULONG_PTR m_gdiplusToken;

// Initialization of GDI+ library.
Gdiplus::GdiplusStartupInput gdiplusStartupInput;
Gdiplus::GdiplusStartup(&m_gdiplusToken, &gdiplusStartupInput, NULL);

The GdiplusStartup function initializes GDI+. Call GdiplusStartup before making any other GDI+ calls, and call GdiplusShutdown when you have finished using GDI+.
