I need to unarchive the Print Screen function of a file.

The file I posted was the same one I found on the internet.
This code works on this file, but when trying to run in the 2013 version it gets in error.

Would anyone know how to solve it?

Thisworkbook:
Code:

Private Sub Workbook_BeforeClose(Cancel As Boolean)
    UnsetKeyboardHook
End Sub


Private Sub Workbook_Deactivate()
 UnsetKeyboardHook
End Sub


Private Sub Workbook_Open()
    SetKeyboardHook

Hi
Yes my system is 64 bits, but still it continues with the error.


I'm going to put the Print of the 1st error, so I added the PtrSafe.


Then the second error appeared, as shown in Print 2.




Error 1

Compile error: The code for this project must be updated for use on a 64-bit system. Review and update the Declare statements, and then mark them with the PtrSafe attribute

[/COLOR]Error 2
Compile Error: Incompatible Types

I tested it on my home computer, and it did not work. But I want it to work on 64 because I'm going to use the company I work for, and they only use 64.

The following should work for all systems 32 as well as 64 its :

    End If
    
End Function

Note that setting this keyboard hook in this fashion is very dangerous as any unhandled error while the hook is installed will definitely crash the whole application !! so be careful.

Try doing a search for the PeekMessage API with the wRemoveMsg argument set to PM_REMOVE which although requires running a continious loop in the background is much safer ..Otherwise run the above SetWindowsHookEx code from a seperate workbook.

Hi Jaafar,
Still not working.
I'll explain better what's happening now.

In the company where I work has two different machines:

When I add the code in the machine (Print Cpu) the code appears (Print Error).
And in the normal desktop this highlight does not appear in the code and does not work. You know what the reason is?

Print Cpu
[url = [url]https://drive.google.com/open?id=1LgXdyJKDU40K9lwe06hqZJ-LG34ccHoh[/URL] [/ img] [/ url]

Print Error
[url = [url]https://drive.google.com/open?id=1fYmxq8slCh0iHEt4-uK3COdWOfDGzKYj[/URL] [/ img] [/ url]

When I click Compile VBAProject the following error appears (Print Newerror)
[url = https://drive.google.com/open?id=1d043wpDa8knaqyz36FI8ECeVKArtJIQS [/ img] [/ url]

This error appears on both machines

Don't worry about those red lines. They are not compiled in excel editions after excel 2010.


That compile error means that the code doesn't see the lpllkHookStruct Type definition. Are you sure that the whole code I posted (including the declarations at the top) resides in the same standard module ?

Yes, I added all the code you sent in the same module. I tested the code on my cpu at home that has 32bit and it also did not work ...

It should work .. as a matter of fact, I 've just tested the code on a 32bit windows machine Excel 2007 and worked fine as expected.
