By following any one of the hundreds of examples that exist out there for this problem.

Or you could just sub-class the static and give it new behaviours so that (a) it's underlined, (b) has a different cursor (c) has a different colour (d) changes colour once visited (e) performs the desired action upon WM_LBUTTONUP, so long as it was under the mouse when the WM_LBUTTONDOWN message came in.

Remember, google is your friend. (Also, I believe Chris has written an article & class for this)

I haven't gone through the code for the link that I provided you. but the article writer must have used ShellExecute or something like that to help the user navigate to a URL on which he/she clicks. You can replace this code with creation/showing of a dialog

Hi,

You can use CFile, like this you open the file..

char* pszFileName = "c:\\test\\myfile.dat";
CFile myFile;
CFileException fileException;

if ( !myFile.Open( pszFileName, CFile::modeCreate |   
          CFile::modeReadWrite, &fileException ) )

like this you can read and write..

char      szBuffer[256]; 
UINT      nActual = 0; 
CFile myFile;

myFile.Write( szBuffer, sizeof( szBuffer ) ); 
myFile.Seek( 0, CFile::begin );
nActual = myFile.Read( szBuffer, sizeof( szBuffer ) );

Like this you close the file..

myFile.Close();

The price of anything is the amount of life you exchange for it.

Thanks and Regards.

sorry, I didn't notice that aspect of the things Smile | :)

The problem in your code is that you're using CFile::modeCreate, but according to the documentation[^], this flag tells to truncate the file if already existing :

MSDN says:
CFile::modeCreate
Directs the constructor to create a new file. If the file exists already, it is truncated to 0 length

So, you have to add the flag CFile::modeNoTruncate to counter this undesired behavior.
The use of this flag however keeps the file pointer at the beginning of the file. So if you want to append things at the end, you must call once after CStdioFile::Open() the function CStdioFile::Seek(CFile::end).

Does the following work better ?

CStdioFile file;
<font color="blue">if</font> (file.Open(_T(<font color="blue">"\\log.txt"</font>), CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) {
    <font color="green">//file.Seek(0, CFile::end);</font>
    file.SeekToEnd();
    file.WriteString(logfile);
    file.WriteString(_T(<font color="blue">"\n"</font>));
    file.Close();
}

god, I made a typo.

you shouldn't have read

if (_T(file.Open("\\log.txt"), CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) {

but this :

if (file.Open(_T("\\log.txt"), CFile::modeCreate | CFile::modeWrite | CFile::modeNoTruncate)) {

I fixed the previous post BTW.

and sorry, I am at work, and I have no compiler, so I couldn't test it before posting...

Yes you're right.

BTW, you still can call CFile::SeekToEnd() which takes no parameters, and moves directly to the end of file.

anyway, does it work now for you ?

Platform independent library - Suggestions needed

Christian Flutcher3-Sep-08 18:22

3-Sep-08 18:22

Hello,

I am planning to develop an opensource application which has to work on all three popular platforms (Linx, MAC and Windows). The application will have a core engine which is same for all the platforms and the UI will be different for each platform.

For windows, I plan to use WPF and for LINUX and MAC someother opensource UI framework.

I need to make the core engine as platform independent, hence I plan to write it on C++. How do I start about it? I am fairly new to C++ (I know the basics).

I know MFC is only for windows. Is it possible to develop a library which woks on all platforms using VC++? What are the other alternatives I have?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
