CopyFileEx API call

[gonpublic2k]

Excellent! That worked as expected. Much appreciated

[infratec]

I optimized it a bit and structured it a bit better.

It compiles now and is starting, but I have not tested it.

But I think it is really outdated.
So it would be better if you tell us what you want to do, or to have

What I want to have is something that copy files as fast as ROBOCOPY but to display some sort of
progress so tha the user is aware what's going on. At the end a log file of the files that were copied
and all the operations that were performed. Should be a graphical window with the option to specify
a source and destination and perhaps what folders or files to exclude if given the names. Basically,
I want something like I said as fast as ROBOCOPY but with a graphical interface and display a progress
bar or percentage of files and directories copied and a log at the end. That's all. I just don't know how
to accomplish that in PB.

Thank you!!

Hmm...

then use robocopy or rsync in background (hidden with RunProgram()) and catch the output.

Yes, I'd like to do that the problem is I don't find any examples to get me started.

Thank you, unfortunately this code doesn't work. After I input the source and destination the program just quits without any
information. Also, I don't want a console interface, I want a GUI to enter the source and destination paths. Even if robocopy
runs in the background in console mode, I need a way to tell the user something is going on, so a graphical of some sort (progressbar or else) is definetely a plus. Finally, a log of the results to be displayed in a window.

Hi gonpublic2k,

First... WOW! Was that a long time ago, but I have no problem using my Muli-Function Copy Tool on 5.71 (x86) or (x64)

I'm also not sure how robust 'SHFileOperation' is compared to RoboCopy.exe

Having said that... from what I can gather even RoboCopy cannot copy files that are locked open (or in use)



For this I'd suggest: GSCopyPro Version 8.1 https://www.gurusquad.com/GSCOPYPRO

GSCopyPro comes with an 'open file agent' which can copy files that are locked/ opened by other processes.

This point is crucial when copying server files... there is 'always' an open file somewhere in the system. {grin}

Here's their basic help PDF: https://www.gurusquad.com/GSCOPYPro_v81_Admin_Guide.pdf

PS - The 'Enterprise version' has even more options.
• Operates real-time.
• Provides byte-level file replication to save on bandwidth and file copy time.
• Uses compressed data during transmission, making transfers much more efficient and robust.
• Provides WebDAV support.
• Provides the option to replicate data across the internet with data being highly encrypted during
transmission.

Ya kind'a get what you pay for when it comes to backing up servers.

Hi BlueB ,

Thanks for the reply. Well, reading on the ROBOCOPY information, you can actually copy files in backup mode which takes care of the issue if a file
is locked. I want to write something in PB myself and not have to use any commercial solution, for that there are many out there, this is more of
a personal project that I want to complete in the process learn PB while I'm at it. If you think that 'SHFileOperation' can be as fast as ROBOCOPY
then I'm cool with that but I still need to modify it so that it creates an interface where the user can provide some options to exclude certain files
or folders if needed to. Having said that, I believe that your script will be more robust if it had those options included. I just don't know how to
add them. I'll keep exploring the forum and asking for help until I get that part resolved. I appreciate everyone's help so far, this is a great community.

Hello all,

Going forward here's what I want to accomplish in my adventure of discovering the power of PureBasic. The following
illustrates at its best what I want to do, exactly what I had in mind - if there's a way to replicate something like this in
PureBasic then I'd be happy:

https://sourceforge.net/projects/robocoprobocopy/

Check out that project and let me know who wants to join me in this adventure!



Thanks!!

Read the help about RunProgram() carefully.

Then you will also notice a flag called #PB_Program_Hide

It is possible with PB.
You have simply to do it.

Build your GUI, then start robocopy with the correct parameters in background and collect the output.
Both, stdout and stderr.
You have to do this in a thread to be able to update your GUI.

Hi gonpublic2k,

The fact that Microsoft has deprecated 'SHFileOperation' for 'IFileOperation'
leads me to favor RoboCopy... which has way more parameters (and option flags).

...you can actually copy files in backup mode which takes care of the issue if a file
is locked.

I'd be wary of that statement... look into this closely.

Another issue is long path names, I believe RoboCopy can handle this issue.

There are a lot of possibilities when you want to create your own programs with PureBasic...
- 'SHFileOperation' or 'IFileOperation'
-Xcopy
-RoboCopy
-RichCopy

And, using PureBasic as a front-end, you can always use proprietary 'command line tools' such
as GSCopyPro (and many others)... it just depends on how deep you want to go down the rabbit hole.

It's great that you want do it yourself to learn rather than using a ready-made product.
So we're not going to do it for you, but give you the method.

A good point is to make a progressbar and to do it, you musk know how many files need to be treated
To make a progress bar, you make a first pass of copy simulation (parameter /L) which allows you to count all the programs that need to be added, modified or deleted.
Then, you run Robocopy in the background and for each displayed line (updated, added, del), you advance the progress bar.

I think Robocopy can copy open files using the Volume Shadows Copy system (I don't remember how it works anymore)
That being said, the principle of a file backup is to make it run off-connection (users) for users and otherwise we inform them that they must close their files at such time and that otherwise they will not be backed up.
For some files such as those in databases this is not a problem because the copy is made using replication system or use Dump file.

That's correct Marcus. Thank you all for your support and feedback. I'm not sure if the progressbar method of calculating what files are going to be copied and parsing that
information to ROBOCOPY is a efficient method of doing it. What about a job that you have no information of what folders, files or otherwise is going to be copied? I believe
that the program should take whatever parameters you throw at it and use robocopy in the background to perform the copy process and somehow capture the information
and display it using a progressbar or showing it on the screen as it copies it, or both. Getting that to work together is the major task that I have in front of me now, I'll have
to study a lot of code in order to get me started. Thank God there are plenty of examples and code snippets in this forum to help me get started and that I have the support
of people like yourselves. Thank you.

A progressbar needs always an end value.
If you don't have one, you end up with progressbars which are starting again at 0
