I've written an application which will use virtual COM port (USB-to-Serial) to communicate with my device. I am using CreateFile/ReadFile/WriteFile functions. It is running fine until one issue found.
With the application open, when (somehow) the USB driver reload, my application fail to perform read/write. Even after I close the application and reopen it, it fails to get the handle.
Why is it happen? Are there anything that my application need to do when the USB driver is re-loaded?
Thanks.

:(CString FilePath;
FilePath = writeFilePath+ DMID + "." + test;
// then FilePath = c:/temp/1234.jpg
objEWFFile.Open(FilePath, CFile::modeCreate | CFile::modeWrite, NULL);
It doesn't work...
How can FilePath change to LPCTSTR ??

In what way? What errors do you get? When do you get them, compile time or runtime?
Did you debug your source code?
|

You can do this as
CString str="abcd";
const char* data_char = (LPCTSTR) str;
//However you shouldn't be having any errors with opening the file using a CString type filename
Somethings seem HARD to do, until we know how to do them.

CString has a LPCTSTR cast operator, which means you can safely do
LPCTSTR lpStr = (LPCTSTR)oMyCStringObj;

What is the type of objEWFFile??
Knock out 't' from can't,

Are you sure the // FilePath = c:/temp/1234.jpg path is correct?
check it and try following for opening file.
objEWFFile.Open((LPCTSTR)FilePath.GetBuffer(0), CFile::modeCreate | CFile::modeWrite, NULL);<br />
FilePath.ReleaseBuffer();
Knock out 't' from can't,

Hi,
Iam writing a ComPort related program. Iam setting the state of the com port using SetCommState(). Iam considering stop bits also. When I use 1 or 2 stop bits , SetCommState is working fine. But when I use 1.5 (ONE5STOPBITS), SetCommState() is not working, i.e its returning 0.
Why is it not working?What changes should I make?
Thank you.

Check EN_CHANGE and EN_UPDATE Notification messages

Derive it from (subclass)CMyEdit and override the WM_CHAR.

CString ::Right(), CString::Left() may help
