Hello,

I have a simple problem. I want to save a file from ms access to the desk. However, chars are being added at the beginning of the file and when I'm extracting the files it's being corrupted.

Here's my application:

If I manually remove the added chars the file works just fine.

How can I fix this?

Thank you in advance.

Hi: i950;

I had no problem running the program and creating the file. When I ran WinZip on it, it uncompressed the file giving me two extracted files, it121_setup.exe and Readme.txt. I opened the readme file and it looks fine. What extra characters are being added on your system?

Hello,

It only works with WinRar not with WinZip. When I try it with WinZip I get:

error [c:\test.zip]: start of central directory not found; Zip file corrupt.
Possible cause: file transfer error.

The added characters differs from one editor to another. Here's what I get when I open it with NotePad:

$            Binary  Binary           Binary          ,؛  

Thanks.

Hi i950;

I looked at the two files the one you sent as the original and the one that I get from the DB file in your project.

   Original   =  47,660 Bytes
   From DB =  47,728 Bytes

And the byte values were all different as well as the two file being of different size. I suspect that the compression algorithm  that was used to compress the files were different. But I was able to uncompress both with no problem using WinRNR, I could not try WinZip because I do not have it on my machine.
