1. You can do this from one of the debug windows (Autos, Locals, Watch etc). Just click on the variable's value and change it to whatever you want it to be.

2. All backslashes in a string need to be escaped thus:

CString path = "c:\\Temp\\bin_Images\\abc.txt";

Text getting truncated

Hello,

I am finding an issue where in I have a Text which is longer than a single line with no spaces. This text is not displayed completely in the tool tip. It gets truncated.

I make use of CDC for the tooltip display rectangle,

CDC* pDC = GetDC();
CRect rect(0, 0, 0, 0);
CString sComment = "this is a comment bigggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg comment 2 2 2";
pDC->DrawText(sComment, &rect, DT_CALCRECT | DT_LEFT | DT_WORDBREAK | DT_NOPREFIX | DT_TOP);
int iheight = rect.Height(); // It wont return the correct rectangle height

//Output is
this is a comment biggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggggg

Can anyone tell me what the issue is.

Thank you,
~ Vikram

If you don't like the clipped text, then why didn't you specify the DT_NOCLIP formt?

I need the text to be displayed on multiple lines, but i need to avoid text truncation.

I suppose you got the wrong height because you've passed an empty rectangle to the function.

Interestingly this is an exact duplicate of this question[^], even though the ids are different. I cannot believe that two different CP members randomly created exactly the same issue in the last few days. Are you (or the other person) perhaps a sock puppet?

Problem while displaying "Greek" and "Russian" Strings

Re: Problem while displaying "Greek" and "Russian" Strings

18-Oct-10 23:31

I am facing a strange problem.

In my dialog application (Win32), I have a button control.
I am loading a "Greek" string ("Επιλογή Εκτυπωτή")from a string DLL and trying to

>Case-1
display on the button control.

>Case-2
And also I am trying to use the same string to set the dialog's title.

But here the problem is,on the button, text is displayed correctly, but dialog's title displayed as
"?p???? ??t?p?t?"

I am using (both for Case-1 and Case-2)

>LoadStringW to load the string
>SetWindowTextW to display

While debugging, I found that strings are loaded properly in both the cases.
I have also tried by changing code pages using setlocale API.

But I couldn't solve this issue.
Please provide me some tips so that I can move forward.

Thanks in advance

The difference is on the font used for the two items: are you sure that the font used for window titles supports greek characters?

I have seen the dialog properties, the font is Microsoft Sans Serif.

I think this font supports Greek also. Check

I have just used your Greek phrase to set my dialog title and it appears correctly (font is MS Sans serif), so I cannot see what is different between your code and mine. Maybe you could show a bit more of your code as there may be a clue that you have missed.

Hi, thanks for the reply. Here is my code.

WCHAR* chr = L"Επιλογή Εκτυπωτή";
HWND hWnd = ::GetDlgItem(m_hWnd, IDC_BUTTON);

::SetWindowTextW(m_hWnd,  chr);
::SetWindowTextW(hWnd,  chr);

>> Where m_hWnd is handle to the Dialog and hWnd is handle to the Button.

>> Output

>> Button - "Επιλογή Εκτυπωτή"
>> Dialog's Title - "?p????? ??t?p?t?"

That is basically what I did and it worked fine. It would appear that the system is trying to translate the characters to a different font in the title of the dialog bar. I can only suggest rechecking your dialog settings, including verifying that the system is not sending a WM_SETFONT message which is changing it from your original font selection. Other than that I'm a bit lost I'm afraid.

I am often reminded of a sentence in "Programming Windows 3.1" by Charles Petzold where he says (if I remember correctly): "No-one said it has to be to be easy". Frown | :(
