For this, I have said to use SeekToBegin. Hope it will work.

Something like this.
<br />
void CSRFToolDlg::OnBnClickedRead()<br />
{<br />
TCHAR tempBuffer[256] ;<br />
UINT readText = 0;<br />
openFile.SeekToBegin();<br />
readText = openFile.Read(tempBuffer, 256 ) ;<br />
SetDlgItemText(IDC_S_READ, tempBuffer ) ;<br />
}<br />
This code given by Naveen.R and seems it is work. But one issue is there, can't read line of text more than 256 characters.
I appreciate your help all the time...

You are reading only 256 at the maximum.

Actually that what I'm try to change. Want to set it to the length of a line of test(a string).
I appreciate your help all the time...

One solution can be as follows...
while( Not EOF file)
{
read the file.
add to a cstring.
}
set the cstring to edit control

come on,
now initiate a loop, and read character by character and save them to an array.
or
i think, CFile returns you the nuymber of bytes in the file, so, read that many number of bytes. iam not sure but just try it.
|
|
|
|
|
I think it is possible using CFile::GetLength(). Wait, I'll test it now.

I think _UNICODE is defined your project so you are writing some wchar and trying to read some multi byte cahracters. try changing the following way
void CSRFToolDlg::OnBnClickedRead()<br />
{<br />
TCHAR tempBuffer[256] ;<br />
UINT readText = 0;<br />
readText = openFile.Read(tempBuffer, 256 ) ;<br />
SetDlgItemText(IDC_S_READ, readText) ;<br />
}
|

|

I think the issue is on UINT. Is says that cannot convert parameters of SetDlgItemText() from 'UINT' to 'LPCTSTR'
I appreciate your help all the time...

I just noticed you are trying to set the number of bytes returned by the read() function. If you want to set the read text change the readText with tempBuffer.
SetDlgItemText(IDC_S_READ, tempBuffer) ;
|
|
|
|

I want to print the text which is write to the file. No need to find the number of bytes. Initially I've tried this one also. What happened is print some annoying text on the edit control. It is true, because the buffer is size of 256 which I've defined.
I appreciate your help all the time...

did u try after changing the char tempBuffer to TCHAR tempBuffer?
|
|
|
|
|
Yes I've tried it.
<br />
UINT readText = 0;<br />
readText = openFile.Read(tempBuffer, strlen(tempBuffer)) ;<br />
It's gives the error on above code. Gives an error on UINT and LPCTSTR. But I can't find any such conversions.
I appreciate your help all the time...

This is not the code I suggested you earlier
void CSRFToolDlg::OnBnClickedRead()
{
TCHAR tempBuffer[256] ;
UINT readText = 0;
readText = openFile.Read(tempBuffer, 256 ) ;
SetDlgItemText(IDC_S_READ, tempBuffer ) ;
}
The readtext is having the number og bytes read by the read function. And you are trying to set that UINT value to the edit box???? the tempBuffer containes the data actaully read from the file.

No dear, I'm talking about the same code as you say. I check all your suggestions, as I said earlier post it print some annoying characters except the text on the file. Until it fill-up 256 characters.
I appreciate your help all the time...

ok. that makes sense.
Now can you read the text in the file you open it in notepad?
|
|
|
|

I think you are still not clear on my question. can write anything to a file. But I can't read it still. When I click the read button, by using your above suggestion, it print some annoying(bunch of slashes actually) characters, except the string(letters) on the file. 
I appreciate your help all the time...

Ok. But i just want to ensure that your writing to file is proper. thats why i asked whether you can read the file in the notepad.
Also by the time try setting the tempBuffer as follows. This will set the intial content of the array to 0.
TCHAR tempBuffer[256] = {0};

Oops, you asking that I can read the text file on my naked eyes. Sure I can, that mean my application write text properly.
At the time you know what is the funny thing. When I use an empty buffer, nothing print on the edit control.
I appreciate your help all the time...

ok i think i got the problem. Update the function by calling the SeekToBegin() as follows
void CSRFToolDlg::OnBnClickedRead()<br />
{<br />
TCHAR tempBuffer[256] ;<br />
UINT readText = 0;<br />
openFile.SeekToBegin();<br />
readText = openFile.Read(tempBuffer, 256 ) ;<br />
SetDlgItemText(IDC_S_READ, tempBuffer ) ;<br />
}
|

Seems this is working fine. But one issue is there, if the string length is more than 256 characters. Can I set it to the length of the string which I've already written in the file.
Thanks
I appreciate your help all the time...
