If you've globally set an animated wait cursor then I guess that will be displayed instead of the hour glass. Also you can try LoadCursorFromFile.

I wrote this code in the button click event, but no change in the run time
I get normal pointer cursor. please advice, I want to display animated cursor.

HCURSOR hcur;
	hcur = ::LoadCursorFromFile((LPCWSTR)"C:\\eglobe.ani");  
	::SetSystemCursor(hcur,OCR_NORMAL);

when I add watch for "hcur" it is null and unused

WriteProfileString()

after choosing and closing the Font Dialog in an SDI appliction, the last choosen Fon must be saved via WriteProfileString() and by the next call
it should be loaded sot that the Font is automatically selected via GetProfileString().

I have the following code:

CString strFaceName;
CString strFontSize;
CString strFontStyle;
CString strFontValue;

CFont *m_cfont = (CFont*) new CFont();

LOGFONTA *m_lf = new LOGFONTA();

int m_nFontSize = 0;

CWinApp* pApp = AfxGetApp();

m_cfdlg.GetCurrentFont(m_lf);

strFaceName = m_cfdlg.GetFaceName();

m_nFontSize = m_cfdlg.GetSize() ;

m_cfont->CreateFont(m_nFontSize, m_lf->lfWidth,m_lf->lfEscapement,m_lf->lfOrientation,
m_lf->lfWeight,m_lf->lfItalic,false,0,1,OUT_DEFAULT_PRECIS,
CLIP_DEFAULT_PRECIS,DEFAULT_QUALITY,DEFAULT_PITCH | FF_SWISS,strFaceName);

itoa(m_nFontSize,(char*)strFontSize.GetString (),10);

pApp->WriteProfileString(strFaceName, strFontSize, strFontStyle);

strFontValue = pApp->GetProfileString(strFaceName, strFontSize, strFontStyle);

as i know WriteProfileString, write in the registry, but this code needs something more to work properly?

Your post is confusing, unclear and clueless ALL at the same time. Anyone attempting to answer you will have a tendency to jab a needle into their eye.

However, to answer your post: If the other application has opened the file in exclusive access mode, you will not be able to even read it. Again, if you do have access to the file, it is not clear from your post if you want to save updates to the same file (depends on if the application that created the file is allowing other applications to perform a write operation on it).

not sure what you mean - if its some sort of program you've written, then its quite easy to keep a 'dirty'/'has-been-modified' flag, set that when ever data is changed, inspect it periodically and save the data if it has been set.

If you mean controlling some sort of other program not written by you then you'll have to supply more information

What is the question ?

do you need help in writing files of different formats ?
or
do you need help on how to implement an auto-save feature ?

ANSI to UTF-8

Hi there,

I found a code snippet on the web which converts an ANSI string to UTF-8 format. I implemented it in my own and it works.

<br />
////////////<br />
// to UTF-8<br />
char text[1024]={0};<br />
WCHAR w[1024]={0};<br />
int erg=0;<br />
<br />
strcpy(text, m_pData);<br />
<br />
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, sizeof(w) / sizeof(WCHAR)); // ANSI to UNICODE<br />
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, sizeof(text), 0, 0);	    // UNICODE to UTF-8<br />
//<br />
////////////<br />

After that 'text' is UTF-8 formatted just nicely.

Now I was wondering, why doesn´t the following (slightly altered) code not work? I just created a char* instead of char[];

<br />
////////////<br />
// to UTF-8<br />
char* text = new char[1024];<br />
WCHAR w[1024]={0};<br />
int erg=0;<br />
<br />
strcpy(text, m_pData);<br />
<br />
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, sizeof(w) / sizeof(WCHAR)); // ANSI to UNICODE<br />
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, sizeof(text), 0, 0);	    // UNICODE to UTF-8<br />
//<br />
////////////<br />

Thanks,

Souldrift

My guess is in the first example the sizeof operator can calculate the size of the array. When it comes to pointers - no such luck. Try passing the size of the allocated memory directly (preferably by using a #define):

#define ARRAY_SIZE 1024
erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, ARRAY_SIZE); // ANSI to UNICODE
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, ARRAY_SIZE, 0, 0); // UNICODE

Try to avoid using numbers directly or hard coding instead store in a constant.

const int SIZE = 1024; // Bytes
char* text = new char[SIZE];
WCHAR w[SIZE]={0};

erg=MultiByteToWideChar(CP_ACP, 0, text, -1, w, SIZE); // ANSI to UNICODE
erg=WideCharToMultiByte(CP_UTF8, 0, w, -1, text, SIZE, 0, 0); // UNICODE to UTF-8

So when you change SIZE, this code still keeps working.

Thanks. That to both of you. That works.
Problem is that I wanted to avoid a const size and instead use the variable size of m_pData (the original text). Is that possible?
