You did not say how big the file is, but it is conceivable to read the file into a CString variable, make the necessary modifications, and write the CString variable back out to the file. Depending on how you want to alter the data, using a LPBYTE type instead of a CString object is also possible.

how do you convert double to char? i mean to keep it the way it is as double for display.
exp: 3.5 will be 3.5 as char (maybe to CString or array since this is 3 characters)
|
|
|
|
|
CString str;
double dblValue = 2.25;
str.Format("%0.2f",dblValue);
Hope it helps

If you use CString to store the value, try the "format" method.
If you use char * , try to use "sprintf".
If the result will put into unicode string, try "swprintf"

Hi,
In my application I get the recent opened file from m_pRecentFileList variable. Here is the code
CString the_File=(*m_pRecentFileList)[0];
OpenDocument(the_File);
In OpenDocument I have
pDoc->Load(CComVariant(lpszPathName));
Here it always fails.
But If I give the path directly,
ie CString the_File="c:\\text.abc"
It works fine.
Regards
Neha

pDoc is an XMLDocument object:
Here is the source:
IXMLDOMDocument *pDoc;
CoCreateInstance(CLSID_DOMDocument, NULL, CLSCTX_INPROC_SERVER,
IID_IXMLDOMDocument, (void**)&pDoc)

Have you put a breakpoint on this statement to see the value of the_File ?

This is a new configurable setting of windows XP. You have to change the OS options under your display settings.

Here you go.
bool dirExists
(CString strDirectory)
{
TCHAR* fullPath = _tfullpath (NULL, strDirectory, 0);
if (fullPath == NULL)
return (false);
TCHAR szCurrDir [_MAX_PATH];
_tgetcwd (szCurrDir, _MAX_PATH - 1);
long nStatus = _tchdir (fullPath);
_tchdir (szCurrDir);
free (fullPath);
if (nStatus == 0)
return (true);
return (false);

You can do a simple check like this
use
GetFileAttributes(..) to get the attributes of the folder, if you receive valid values that means that directory exits, elese its not there.
BOOL CheckExistedFolder(CString strFolderName)
{
if(GetFileAttributes(strFolderName) == INVALID_FILE_ATTRIBUTES)
{
return false;
}
else
{
return true;
}
}

You also might want to check the attributes for FILE_ATTRIBUTE_DIRECTORY to make sure it is not a file.

_access() , GetFileAttributes() , and CFile::GetStatus() are my favorites.

Hello.
I am designing an application that requires the support of SSL/TLS layer socket transfer. I would like to know what is the most extensible solution.
- OpenSSL
- Win32 SSL API
The Win32 SSL API is quicker in terms of implementation. OpenSSL requires the use and in-depth knowledge of how the library handles I/O.
My primary concern is with non-blocking I/O model. Part of the design includes an OVERLAPPED I/O model via winsock. I have no problem blending Win32 SSL API with the current OVERLAPPED I/O. However, OpenSSL is somewhat different. Here is what OpenSSL design could end up.
- Winsock connect
- Associate socket to OpenSSL layer (global context)
- OpenSSL connect
- sent/recv via OpenSSL API
OpenSSL does support an event callback interface. However, is its send and receive API blocking or non-blocking? How will it affect the winsock OVERLAPPED layer? In other words, if there is incoming data, will OpenSSL handles the callback or will winsock handle the callback?
Thanks,
Kuphryn

Anyone know how to accomplish this? I want an effect similar to the one that Trillian uses for its custom buttons.
