I don't think there's a huge performance loss when using CString; internally, it must be similar to using LPCSTR ( char* )é

For day to day operation, just the simpler usage of CString ( or std::string ) makes it up for the programmer at least.

it depends on how you use it! Smile | :)

CString is realy OK, the only thing
you should do is, if you pass a CString
as a parameter, pass it as const CString&
and dont an a lot of small datachungs
to a CString in a loop

int n=0;
CString dummy;
while(n<10000) {
 dummy+=(char)((n%30)+30);
 ++n;
}

AfxSetAppName( )?

I have an SDI application. The title bar text is:

FileName - AppName

My question is: how can I change AppName on the fly? I have a menu item to swtich between two options. I want the application title bar to reflect which option is currently selected. So I want the title bar text to be something as:

FileName - AppName option1
or
FileName - AppName option2

I searched MSDN, and found there is a function AfxGetAppName( ), but it is to get CWinApp.m_pszAppName. Is there a function to set the m_pszAppName?

Thank you very much for any hint.

So there are two major activities in your project.

1) Workiing with Serial Ports
2) Working with Modems

Which one do you want or need help with?
You might get more response to smaller more specific questions.

You must provide more specific information than that in order for someone to determine how to help.

CFileDialog - customize

Hi, I want to pre-configure the state of the a CFileDialog (dialog) I use. What I want is the view to be set to "view Large Icons" or thumbnails.

Also, in another question, can I use the "Search (results) dialog" like a CFileDialog. My use would be a file/folder browse dialog that shows all possible files that match a certain file extension (.BMP,.JPG,.ICO) all under a common root folder.

Thanks!
Regards,
Johnny

Defaulting to large icons is easy enough using both CFileDialog and GetOpenFileName(). However, I've not been able to default to thumbnails using CFileDialog, only GetOpenFileName().

Either the parent frame is the desktop or the parent frame is a direct descendent of the desktop. Put a breakpoint on that line to see which of the two conditions is evaluating to FALSE.

Hi Raghunandan,

Did you subclass a view? It sounds like you are using a view where you should have a window. For example, CListCtrl is derived from CWnd but CListView is derived from CView.

Hi,
Mine is an SDI application where I do like this:
CSingleDocTemplate* pDocTemplate;
pDocTemplate = new CSingleDocTemplate(
IDR_MAINFRAME,
RUNTIME_CLASS(CConvertDoc),
RUNTIME_CLASS(CMainFrame),
RUNTIME_CLASS(CConvertView));
AddDocTemplate(pDocTemplate);

in my initinstance

CMainFrame is derived from CFrameWnd and CConvertView is derived from CEditView.

Is there any problme in this kind of creation?

UNC paths and CStdioFile

pranavamhari14-Jul-04 2:51

14-Jul-04 2:51

Hi,

My program uses 'GetspecialfolderPath(CSIDL_PERSONAL)' to retreive the my documents folder, and saves a file in the folder using CStdioFile.

On Win2000 this my-docs folder path is returned as an UNC path like '\\server\\..$\my documents\...'

Here, CStdioFile fails to create the file. I guess it is due to UNC name. How can I convert this to the mapped drive ?

or is there any workaround ?

Please help, thanks in advance to all.
