Hi,

How can I get the last part ("1") of the file name using strstr or something else ???

char dtSrt[BUF_SIZE] = "C:\\Test\\6.20.1.txt"		
char *pdest;
pdest = strstr(dtSrt,""); // ?????

Thnx again

Searching a bit longer proves to be a good option for me .... Unsure | :~

char dtSrt[BUF_SIZE] = "C:\\Test\\6.20.1.txt"
char *pdest;
pdest = strrchr(dtSrt,'.');

if( pdest > dtSrt )

char c = pdest[ -1 ];

This will point you to the dot separating the file's name from its extension:

char *pExt = PathFindExtension(dtSrt);

CFile open and create file

I want to lock a file so that another application will not be able to open it. I am using CFile.open method with the flags CFile::modeRead|CFile::shareExclusive. However, after opening the file (and keeping it open) I am able to open the file using the windows api CreateFile function. How can I lock the file so that, the CreateFile function will fail?

I found out the problem. If you use createfile function with dwDesiredAccess flag as 0, then it will not try to open the file. It will only check whether the file exists.

I don't think that is a solution, at least for the problem you posted.
What will happen if another application tries to open your file?

if you can send the file, may be someone can chk it. I don't understand any particular reason for this to be possible. Like i told you window's does force not to write on a file that is being used.. u can get the exact details from the book "Windows Driver Development"

Changing default speaker configuration on Vista

i am preparing application to test sound at different speaker configuration for Windows vista and Windows XP.
for doing this i am using API SetSpeakerConfig() to set the different configuration and API GetSpeakerConfig()for getting same configuration.
this is working fine in Windows XP. but not in Windows Vista.
The call to SetSpeakerConfig() succeeds in Vista, but doesn't actually change anything.
Is there any way other than by using the Sound control panel.

SYSTEMTIME sys;
GetSystemTime (&sys);
//sys.wYear has the year that you require

Also you can have a look at
CTime::GetYear()

Somethings seem HARD to do, until we know how to do them.

Well, yes and no. If I statically link some libraries to the application and fiddle with it's settings it works (local & other computers), and on the other hand if I don't do it I get and error when I want to run the exe on a different machine. Someone told me it has to do with CRT dll's and the whole .Net Framework ... and it's a long story ... thanx for asking Naveen

Wow, that would need that you need to know the format of PDF and encode everything yourself. That's a quite a bit extreme. Why don't you simply use an existing library that does the job for you ?
You can find one here[^] for example (I'm sure if you search a little bit, you'll find plenty of).

Hello All,

I have a List Box { IDC_FILE_LIST } and add button { IDC_FILE }

When we click on the add button it should popup a window where we can browse some file name with path and it should be added to list box.
For that I have used the below code but I am getting errors can anyone please tell me what is wrong in the below code.

BOOL CALLBACK DlgProc(HWND hwnd, UINT Message, WPARAM wParam, LPARAM lParam)
{

switch(Message)

OpenFile(hwnd);
break;

OPENFILENAME ofn;
char szFileName[MAX_PATH] = "";

ZeroMemory(&ofn, sizeof(ofn));

ofn.lStructSize = sizeof(OPENFILENAME);
ofn.hwndOwner = hwnd;
ofn.lpstrFilter = "Text Files (*.txt)\0*.txt\0All Files (*.*)\0*.*\0";
ofn.lpstrFile = szFileName;
ofn.nMaxFile = MAX_PATH;
ofn.Flags = OFN_EXPLORER | OFN_FILEMUSTEXIST | OFN_HIDEREADONLY;
ofn.lpstrDefExt = "txt";

if(GetOpenFileName(&ofn))
{
HWND hEdit = GetDlgItem(hwnd, IDC_FILE_LIST);
SendDlgItemMessage(hwnd, IDC_FILE_LIST, LB_ADDSTRING, 0, (LPARAM)ofn);
}

}
