I think _T macro is giving U a problem

char* pFileName = "mysetce.txt";
CStdioFile f1;
if( !f1.Open( pFileName, CFile::modeCreate
| CFile::modeWrite | CFile::typeText ) ) {
exit( 1 );

Hi, thanks for your help.

When i used your method, which is:
char* pFileName = "mysetce.txt";

Im getting this error:
'Open' : cannot convert parameter 1 from 'char*' to 'const unsigned short*'

But this below, doesnt give me any error:
CString fname=(_T("mysetce.txt"));

In addition, Im trying to read a file not write to a file.

However, at the point of 'open', i get this 'Assertion failed' message-box which doesnt help me much

Windows CE does not support CStdioFile

But still im having problem even when I use CFile, although not the same problem!

Here is my code:

char pbuf[50];
CFile f;

if( f.Open(L"mysetce.txt",CFile::modeReadWrite|
CFile::shareDenyNone) )
{
UINT d= f.Read(pbuf,50);
f.Close();
str = pbuf;
}

The file "mysetce" is a text file and its not empty.
This 'Open' process above goes through with no error and it runs BUT 'pbuf' remains EMPTY !!!!! (it doesn't read into it) WHY?????

What's returned in "d"?

How about Rewinding to the beginning, (just a precautionary measure).
Maybe something like
Seek(CFDile::begin, 0 );

I guess it should work then.

its retuned zero in "d"

dear waseemanis, my palm top is currently away, so Im going to have to wait for another 2 weeks.
I will let you know as soon as I try your test.
Thanks a lot for your help.

How about trying on Emulator.

ASKER

You cannot test/debug for open/read/write files on the Emulator

So I should wait till I get my palm top back.

Thanks

waseemanis

why sure you can...all youy need to do is to empfile to the emulator.
Try it !!
Luck Waseem.

Have you tried something like:
TCHAR szName[32] = TEXT("MyFile.TXT");
and then use szName as your file name in the open call?

Is there some difference between using CFile and the API MOIN ???
I guess CFile would work perfect.
