Problem with creating DLL

Thorsten · Post by **Thorsten** » Sun May 04, 2003 1:43 pm

My DLL Code:

ProcedureDLL.l GetFolder(Mainfolder.s, Patter.s, Number.l, Gadget.l)
  
  Protected Mainfolder
  Protected Patter
  Protected Number
  Protected Gadget
  
  ;Number := Freie ID
  ;Patter := Welche Dateien sollen ausgegeben werden? Beispiel: *.exe
  ;Mainfolder := Ordner, wo die E-Mail Daten gespeichert sind
  ;Gatget := Die Gadget Nummer des Zieles
  
  Protected What.l
  

  
  If ExamineDirectory(Number, Mainfolder, Patter) <> 0
    
    ClearGadgetItemList(Gadget)
    
    Repeat
      What = NextDirectoryEntry()
      If What = 2        
        AddGadgetItem(Gadget, -1, DirectoryEntryName()) 
      EndIf
    Until What = 0
    
    ProcedureReturn #True
    
  Else
    MessageRequester("Fehler","Das Datenverzeichnis kann nicht durchsucht werden!",#MB_SETFOREGROUND|#PB_MessageRequester_Ok|#MB_ICONEXCLAMATION|#MB_DEFBUTTON1)
    ProcedureReturn #False
  EndIf  
  
EndProcedure

I create now a DLL. Then I copy the new PureBasic.dll to my program
directory and rename it.

But any time the OpenLibrary() function don't work. I can't open my own
DLL ....

I use the newest PB version with all updates from
http://www.purebasic.com/update/

Did you disable the debugger when creating the dll?
I heared there are some problems when not.

I am also not sure, if stuff like AddGadgetItem() works with Gadgetsthat are created from the main program. You'll have to test that.

Yes - the debugger is off

But I can't test the Gadget things, if the simple
OpenLibrary() don't work

Any idea?

What's about this: Any one from you make for me the DLL
(see the code at top) and I test it.

If this is okay, my PB have a problem. If not - maybe PB have
a bug.

I've tested your code on my system (WinXP SP1, PB3.62 + latest updates) and the OpenLibrary function worked without problems. But you must SAVE your source with the loading rountine first (in same directory as the renamed Dll)...
See also my more detailed answer on your thread in german forum.

Ohh ... I have found the problem

What have I do?

I have erase my complete PB. Then I have my PB 2.9
install and then the update to the newest version.

Then: All is okay, my DLL work's fine

But: If I copy the updates from http://www.purebasic.com/update/
to my PB, the DLL don't work

So - the updates have a new bug

!!!

Sorry - the updates are okay

I have test it a little bit, and the error is inside the editor 8O
If I start the editor first time, and I make then my DLL, all is okay.

But if I make the DLL again - I can't use the DLL.
If I restart the editor - all is fine. But only for the first DLL ...

Hmm ... is hard to describe with english ....
