Hi,

If we click on the file the contents can be read {text file}.
I want to know is there any way I can make a file unreadable when its opened from outside, I want to know to how to compress when file when it is closed and uncompressed when it is opened by the program.
Can u please give me some suggestions.
Thanking you,
Suresh H.

Why don't you encrypt/decrypt it?

You can find several in Criptography[^] category.
I have tested this one[^] and I think you could use it. All depends on the degree of security you need or if you just needs a first stop for a possible opener.
I hope it helps,

Dear Sir,
I still have difficult to do printPreview.
I need to do printPreview without doc/view facilities , to preview more than one pages.
And I can have more than one dialogs to preview.
Who can help me?

I go directly to the printpreview adresse.
After doing all, I have this message on #include "PrintExtension.h";
fatal error C1083: Cannot open include file: 'PrintExtension.h': No such file or directory
What to do ?
|

check you have this file and check path from this file is correct
|

Whar is true is that this fine don't exist, we have only *.lib and *.dll that I put thoses in the program path and c:\windows\system32, but still have the same error

From the demo example copy this file to my path but i have this message:
C:\backupmik\research\help\dialogpreview.cpp(16) : error C2039: 'classCPrintPreviewDialog' : is not a member of 'CPrintPreviewDialog'
I don't understank because this file I copy it like that from the dem project.

error C2039: 'classCPrintPreviewDialog' : is not a member of 'CPrintPreviewDialog'

You get this error "Cannot open include file: 'PrintExtension.h':"
so you include this file and compiler cant find this file so it show this error to you

Excuse me, i was create CFormView instead of CDialog.
Now I coorect it, no compilation error but in execution, they ask me PrintExtension.dll. I don't see this file because i have only PrintExtensiond.lib(PrintExtensiond.dll).

I was unable to figure this out with http://www.codeproject.com/printing/printextension.asp[^]. This was a big problem for me because I need this functionality to work. So what I did was write everything into a dc in memory and then found some functionality to rotate the dc 90 degrees. After rotating it 90 degrees I was then showed the print preview. Even though the print preview was still showing portrait everything was rotated 90 degress so it was really landscape.
I know this seems pretty complicated and it was. Like I said I had to make this functionality work....and I did. It just took a lot of work.
