How to open a file using openfile() method...

Hai...

i'm triying to open a file in read mode using the following method..

HFILE hFile;
hFile=OpenFile("D:\ss.doc",lpReOpenBuff,OF_READ);

i cant undestand what is the 2nd parameter is...

the syntax for openfile is

HFILE OpenFile(LPCSTR lpFileName,LPOFSTRUCT lpReOpenBuff,UINT uStyle);


plzz tell me what shall i put for lpReOpenBuff..

senthil.

msdn says:

Quote:

---

lpReOpenBuff
[out] A pointer to the OFSTRUCT structure that receives information about a file when it is first opened.

The structure can be used in subsequent calls to the OpenFile function to see an open file.

The OFSTRUCT structure contains a pathname string member with a length that is limited to OFS_MAXPATHNAME characters, which is currently 128 characters. Because of this, you cannot use the OpenFile function to open a file with a path length that exceeds 128 characters. The CreateFile function does not have a path length limitation.

I suggest:

Code:

---

OFSTRUCT ofs;

memset(&ofs, 0, sizeof(OFSTRUCT));

OpenFile("D:\ss.doc",&ofs,OF_READ);

---

when the call returns, the structure will be filled in with information about the file you chose to open. See the MSDN link for more information.

Hai sun,
thanks for ur reply...

ur help works supervly...

Now i want to open two files, one in read mode and the another in write mode..

and i want to read the contents of the read mode file and write it into the

write mode file...

i had tried the following method...

Code:

---

HANDLE hFile,hFile1;
DWORD wmWritten;
HFILE op,op1;
OFSTRUCT ofs;

memset(&ofs, 0, sizeof(OFSTRUCT));
op=OpenFile("C:\\tab.doc",&ofs,OF_READ);           
hFile = CreateFile(_T("C:\\text.doc"),GENERIC_READ|GENERIC_WRITE,        FILE_SHARE_READ,NULL,OPEN_ALWAYS,FILE_ATTRIBUTE_NORMAL,NULL);
op1=OpenFile("C:\\text.doc",&ofs,OF_WRITE); 

while(op!=EOF)
{
ReadFile(op,lpBuffer,(DWORD)(strlen(lpBuffer)),&wmWritten,NULL);
WriteFile(op1,lpBuffer,(DWORD)(strlen(lpBuffer)),&wmWritten,NULL);
}

---

Here i dont know the parameter lpBuffer...
Shall i put the path or anything?

Can u plzz explain me how to read the contents of one file and write into
another file...

is the above method enough for this process..
thanks...

Don't use OpenFile. It's Win16 legacy. Only use CreateFile.

lpBuffer is just a memory buffer. A char array, for example.

But don't do all this at all. To copy a file, you use the CopyFile API. You don't implement it yourself.
