Selgor here. Matt .. I want to Drag and Drop . Drag an icon or file and put it in a specific place. For example put an icon as a shortcut to a programme on the desktop from its original directory (folder). Can't see how the programme you suggest does that. What am I not seeing, doing ??? Thanks for the reply. Need more !.

Selgor.

The following code lets you drag and drop a file icon onto the textbox control and have that icon's path displayed in the textbox.

include Win32Lib.ew 
 
constant Window1 = createEx( Window, "Window1", 0, Default, Default, 371, 119, 0, 0 ) 
constant txt_FileName = createEx( EditText, "", Window1, 24, 16, 308, 32, 0, 0 ) 
 
procedure txt_FileName_onDragAndDrop (integer self, integer event, sequence params)--params is ( int id, seq FileName ) 
	if length(params[2]) > 0 then 
		setText( txt_FileName, params[2] ) 
	end if 
end procedure 
setHandler( txt_FileName, w32HDragAndDrop, routine_id("txt_FileName_onDragAndDrop")) 
 
WinMain( Window1,Normal )

To create shortcuts, he'll need to use some simple COM calls, a search for "shortcut" in the archive will provide a few different libs to do this.

This is the native behavior of shortcuts in Windows, so long as one's application will take a file name as a single parameter.

So whatever his reason for "upgrading" win32lib, with all apologies to Derek et al, if Selgor put all his required includes in the same dir with his app, including the older version of win32lib, his app may run again.

Seriously? You know you are using the wrong version yet you complain that it's not working?! Have you tried getting the current version and using that?

Seriously? I hope then you are still using Euphoria version 2 on Windows 1.0

I swear i don't understand humans.

Selgor said he lost the win32lib version his app was written to work with because of a system crash. He replaced it with a current win32lib version. His app does not work with the current win32lib, as win32lib versions are generally not backwards compatable. Selgor then asked if anyone has a version 0.57.9 to send him, so his app can run again.

This is where you chime in and ridicule him for using the wrong version (a current version) and ask if he's tried downloading and using a current version.

I have some older versions, but i quit writing for win32lib when it quit being backwards compatable. And i always save an app with the version of win32lib it was written for, because usually no other version will work.

If you are saying that each release of the library completely invalidates all programs written using the previous release then I dispute this. I believe that apart from mistakes (and one release which was announced with at least 12 months notice), each release is compatible with its predecessor. Please give examples in which you can demonstrate backwards incompatibility.

The particular problem you are describing in this thread appears to be one in which recent code won't work on an earlier library - that is not backward incompatibility.

I'm confused then ... in one post you say you are not using the right version and in another post you say you are using the right version.

The error message you are getting implies that the addLVItem() routine being called has the id parameter declared as an atom, but the current version of the library has that parameter declared as an object. So it seems that you are NOT using the right version of the library.

Exactly which version of Win32lib.ew is actually being used by this application?

In the meantime, I'll cut down the program you submitted to the minimum required to demonstrate the issue being discussed.

Be that as it may, the code should run correctly with the CURRENT version. I've got the sample code now running on my system using win32lib V0_70_20 and Eu4.

I don't know what that is, but it sounds like something fairly old. I'm not as, er, adamant about non-breaking changes in Win32Lib as Derek is. I think I was still fairly heavily involved back in the 0.55 days.

I think Derek has gone to a lot of trouble to maintain backward compatibility for some time, which probably explains his comments. If you look at the current library, you'll see compat01.ew and compat02.ew. These are full of deprecated bits of code that allow older programs to continue working.

Yes, I suspect that you might start seeing default parameters used something like this in new development.

Yes, the new ifdef stuff can be used for this sort of thing. Obviously, it makes library development a lot more difficult, so I suspect that if it gets used, it may happen on a case by case basis (if at all). I've been working on Win32Lib in an attempt to port it to run on 64-bit windows, and it is a big, complicated bit of code.

LOL

Selgor here.

Derek . Let's be clear on one thing. The win32Lib used is 0.70.20 . The latest. And the above programme was run under Euphor1a 3.1 . This was clearly stated above.

Now this is what I have done. I downloaded win32Lib 0.70.20 and the new euphoria 4.03. And I cleaned out all my euphoria from one of my other computers. So on this computer NO EUPHORIA IS PRESENT. I installed new euphoria. I installed the win32Library. I made sure the include file contained all necessary .ew's . Then the programme was "installed".

And this is what happened when I ran the programme.

Error message.

C:\EUPHORIA\include\w32file.ew:888 
SHFILEINFO_SIZEOF has not been declared 
    lSHFILEINFO = w32acquire_mem(0, SHFILEINFO_SIZEOF)

C:\EUPHORIA\include\w32file.ew:888 
SHFILEINFO_SIZEOF has not been declared 
    lSHFILEINFO = w32acquire_mem(0, SHFILEINFO_SIZEOF) 

Now I'm not saying that you haven't done what you said you have, but that particular error message is impossible if you are using the v0.70.20 version of the library. I say this because line 888 of file w32file.ew in that version is ...

-- 

Yes, a single comment line with no text. However, in a much earlier version of the library (one that was unofficially amended for the IDE) has in line 888 ...

    lSHFILEINFO = w32acquire_mem(0, SHFILEINFO_SIZEOF) 

This occurs in the function called "getFileInfo()". Now looking at the equivalent line in the v0.70.20 edition of the w32file.ew code, we see ...

    lSHFILEINFO = w32acquire_mem(0, SIZEOF_SHFILEINFO) 

From this evidence, I'm guessing (and its just a guess), that either you have downloaded a different version of the library than you thought you did, or you still have some remnants of an old library hanging about.

So, what is the path to the v0.70.20 version of Euphoria that you downloaded? Is it "C:\EUPHORIA\include\" ?

Also, what is the actual URL that you used to get the download from? Was it either
https://sourceforge.net/projects/win32libex/files/latest/download?_test=goal
or
http://sourceforge.net/projects/win32libex/files/v_0_70_20/win32lib_0_70_20.zip/download

The symbol OFN_EXPLORER is declared as a global symbol in w32constants.ew (line 3875), which is included by win32lib.ew.

Can you confirm if your copy of the file w32constants.ew has that declaration and that you are including win32lib.ew?

I'm sorry Selgor, but are you trying to help me help you? You seem more intent on making it hard as possible to help you.

I'm sure you are aware that I can't actually see your screen, so what exactly do you mean by "many items"? And did it LITERALLY stop at ...

win32lib.ew:(26310)w32Color_WINDOWTEXT..  
class FGColor[lControll]=call_func(pRID[kCRID_Controll],{classPGColor",w32Color_WINDOWTEXT})  

Ok ... I'll make a guess at what you are trying to tell me this time ... you are saying that Euphoria is reporting many items that seem to be undeclared.

So here is my summary of what you are trying to report ...

1. The folder "C:\euphoria\include" contains EVERY include file that is part of the Win32lib library.
2. The version of win32lib that you have in "c:\euphoria\include" is v0.70.20
3. You are running Eu v4
4. When running eui win32lib.ew, with the current directory set to "C:\euphoria\include", Euphoria can find "win32lib.ew" and but is not seeing some, or all, of the symbols in the files that "win32lib.ew" itself includes. (I assume it is not reporting that it can't find the files.)

Is this a fair summary?

Ok, here is something else to try ... Similar to before, run this command line ...

eui -i c:\euphoria\include win32lib.ew 

And this time, if it shows you some ERROR messages, can you tell me what the FIRST error message says.

When you ran the command above, was your current directory set to "C:\euphoria\include"?

If not then PLEASE repeat the command AFTER changing the current directory to "C:\euphoria\include".

If it was, can you tell me (using 'dir' for example) if w32lib.ew is in that directory.

I am unsure that I can help you. I keep getting confusing, conflicting and abridged information. Sorry that my skills do not meet your needs.

Thank you.

Well, not actually. In previous posts you also got a lot of other messages that seemed to have disappeared now.

Again, thank you, but that was not the entire message was it? This is only the first line of a message. What type of error/warning did this line related to?

And by the term "item" I assume you mean "line". Was there any error message to go with line?

Hang on ... you just said the other line was the last line. How can you have more lines after the last one?

Well in that case, there is not much more I can do as I need a lot more information about your set up. There are some strange inconsistencies in what you are reporting, such as message seeming to indicate that Euphoria can't find information in the files that you insist are present and apparently with correct content.

Also, warning message of the type "Warning {not used}" are not the default so you must be running Euphoria with some special switches set. What other switches have are you using that you haven't mentioned? Are there any eu.cfg files that you have hanging around?

Anyhow, sorry I was unable to help.

Hmm. Could you tarball your c:\euphoria\include directory as well as the entire code of your program?

That might allow someone else to sort out the mess and figure out how to clean up your system so as to get the program to run for you.

I'd just say to use eudist, but eudist doesn't work if not all include files can be found.

I understand that this is a clean system, set up just so you can debug this problem. However, it seems you may have accidently copied over some of the breakage when you copied over your program to it.

Yes, I pointed out the demo previously, and he said it wasn't what he wanted, but couldn't articulate why it wasn't what he wanted or how it should be different. His refusal to follow best practices has exceeded his ability to maintain a working system, and that just makes the task of helping him that much more difficult.
