That did it. Thanks Mike.

I wish the debug version of MFC was less forgiving so I could have found it sooner.

have a look at strtime and strdate and related functions to create a formated string of a time and a date.

and to put it on the dialog, create a CStatic and use SetWindowText.

you can do this like that :

CTime t1;
t1=CTime::GetCurrentTime();
((CStatic*)GetDlgItem(YOUR_STATIC_ID))->SetWindowText((LPCTSTR)t1.Format("%H:%M:%S"));

that would be running...

It seems to be shutting down every time a calculation is being made. Any suggestions?

Here is the program. Maybe I just coded something wrong...I dunno. Thanks for the help though.

Anybody have any idea how to solve Brouncker's continued fraction expansion using a recursive function???

ie: 4/pie = 1 + 1^2/(2+ (3^2/2+ (5^2/2+....))).

Thanks.;P

Hello,

I have created an MFC SDI and I want to set the main windows title. At the moment I have:

this->SetTitle("My Name");

But I'm left with a "Untitled" after the title:

My Name - Untitled

How do I get rid of "Untitled" from the title?

Thanks in advance;)

Hi,

I updated from Intellipoint 4.1 to 5.0 but since i don't have the Explore My Computer option for a mouse button assignment i decided to buid my own using the WindowsHookEx and the WH_GETMESSAGE or the WH_MOUSE_LL type for the WM_XBUTTONDOWN and MK_XBUTTON1 to open windows explorer sending the WM_HOTKEY to the Shelltraywindow and it works except for some kind of windows when it opens twice and process message (Back button). Windows like the ones in VS.net tabbed environment, inside a popup menu, some toolbars.

Any ideas will help a lot.

Thanks.

How to get icon given a file extension?

How to get icon that corresponds to given file extension ?
I can't use SHGetFileInfo because file may be not on my hard drive but on FTP server.

Re: How to get icon given a file extension?

Michael Dunn25-Jan-04 18:51

You can indeed use SHGetFileInfo(). Give it a filename of "foo.xyz" (or whatever extension you're interested in, in place of .xyz) and use the SHGFI_USEFILEATTRIBUTES flag. From the docs:

pszPath
...
If the uFlags parameter includes the SHGFI_USEFILEATTRIBUTES flag, this parameter does not have to be a valid file name. The function proceeds as if the file exists with the specified name and with the file attributes passed in the dwFileAttributes parameter. This enables you to obtain information about a file type by passing just the extension for pszPath and passing FILE_ATTRIBUTE_NORMAL in dwFileAttributes.

Question about CDateTimeCtrl

Mukkie25-Jan-04 7:34

Mukkie

25-Jan-04 7:34

Hello!

I used CDateTimeCtrl in my project. Send value from CTime, and I saw, that CDateTimeCtrl controls displays something different from what is present in CTime object.
What I want to do is to display FILETIME in CDateTimeCtrl, or something similar which supports full formatting of date/time.
So I wrote :
FileTimeToSystemTime
SystemTimeToTzSpecificLocalTime
CDateTimeCtrl::SetTime
and it worked correctly.

Great! .... but SystemTimeToTzSpecificLocalTime is not present Windows 98.

Any ideas?

Easy question on CString

Hi,

I have a question on CString. I want to put a multiline string in a CString variable and I don't want to put all the text in one line. Is there a easy way to do it? What I want is something like following.

CString temp;
temp = "aaaaaaaaaaaaaaaaaaaaaaa
bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb
ccccccccccccccccccccccccccccccccccccccc
ddddddddddddddddddddddddddddddddd
ffffffffffffffffffffffffffffffffffffffffffffffffff
fffffffff";

Please advise

CString temp;
temp = "aaaaaaaaaaaaaaaaaaaaaaaaaaaaa"
"bbbbbbbbbbbbbbbbbbbbbbbb"
"ccccccccccccccccccccccccc"
...

The compiler will automatically concatenate the strings for you (without any runtime overhead - all is done compile time).

That seem easy to do.

if you want to split a line, you can do this :

CString temp;
temp = "aaaaaaaaaaaaaaaaaaaaaaa"
       "bbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbbb"
       "ccccccccccccccccccccccccccccccccccccccc"
       "ddddddddddddddddddddddddddddddddd"
       "ffffffffffffffffffffffffffffffffffffffffffffffffff"
       "fffffffff";

you just have to put each lines between "" and that's it, te compiler will automatical concatenate the lines into once.

Control Parent in CDocument

sschilachi25-Jan-04 3:48

25-Jan-04 3:48

I want to create a button control in the constructor of my CDocument class in an SDI program but I cannot figure out what the parent CWnd should be, as it cannot be '*this' as '*this' return a CDocument.

I have tried using the following code:

m_wndButton.Create("OK",BS_PUSHBUTTON|WS_VISIBLE,rect,::AfxGetMainWnd(),IDD_BUTTON);

but I get an assertion error and when I debug it the error line reads:

ASSERT(pParentWnd != NULL);

It seems as though ::AfxGetMainWnd is returning NULL but I do not understand why.

Can you please advise me what to put in place of ::AfxGetMainWnd() so the parent class is the main frame.

Thank you
