Hallo an alle

Ich möchte wissen, ob es möglich ist, zu testen, eine Voraussetzung für die Frage einer DLL, und wenn sie nicht gut zu verlassen, ohne die Upgrade-Funktion aufrufen.

Dies auch, um den Test zu jeder Funktion, ohne daß man jedes Mal

Code des DLL

Code: Alles auswählen

ProcedureDLL AttachProcess(Instance) 
 
 Buffer.s = Space(1024)
 Bufsize.l = 1024 
 GetComputerName_(@Buffer, @Bufsize) 
 NamePc.s = Buffer
 
 If NamePc <> "ComputerName"
  MessageRequester("Test", "The name of the PC is no good", 0)
 EndIf
 
EndProcedure

ProcedureDLL Message() 
 MessageRequester("Test", "Hello is good", 0)
EndProcedure

Code des Programms

Code: Alles auswählen

OpenLibrary(0, "PureBasic.dll")
CallFunction(0, "Message")
CloseLibrary(0)

Ich danke Ihnen
Guten Tag

And in deutch i walk in the complet dark

I have asked the question, in the two forums, because it's a very hard question, same SROD which is a very good programer was not the answer

Well, I called the master Freak and he gave me the answer to ASM
I post the link, if a friend of this forum is interested:

Thanks a lot for your interest

I have a new problem, the code of FREAK works fine for exit a DLL, without execute the rest of DLL.
Directly of the AttachProcess function

It's really useful, for test if a program have the autorisation to use the DLL

It works fine when the DLL called by a PB program, else when the DLL called with VB6, i have an error 48 "File no found : PureBasic.dll"

Somebody know why VB call don't works ?

What is the difference of the DLL management between PB and VB6 ?

Code: Alles auswählen

ProcedureDLL AttachProcess(Instance) 
 
 Global AppPath.s
 AppPath = Space(200)
 GetCurrentDirectory_(200, @AppPath)
 AppPath = Trim(AppPath)
 
 If Right(AppPath,1) <> "\" 
  AppPath + "\" 
 EndIf

 Global NomExecutable.s
 Application.s = Space(255) 
 GetModuleFileName_(0, @Application, 255) 
 NomExecutable = GetFilePart(Application) 
 Application = ""
 
 Global AutorisationAppli = #False
 ReadFile(1, AppPath + "Autorisation")
 
 Repeat
 
  Donnee$ = ReadString(1)
  NomAppliFichier.s = StringField(UCase(Trim(Donnee$)), 1, "=")
  
  If FindString(UCase(Trim(NomExecutable)), NomAppliFichier, 1) 
   AutorisationAppli = #True
   Break
  EndIf
      
 Until Eof(1) <> 0
 
 CloseFile(1)
 
 If AutorisationAppli = #False

  MessageRequester(NomDLL, Space(8) + "Le logiciel " + NomExecutable + " n'est pas autorisé à utiliser " + NomDll + "," + Chr(13) + "veuillez contacter le développeur pour obtenir une autorisation.")

  !ADD esp, 8     ; remove Instance variable and return address from stack 
  !MOV eax, 0     ; set returnvalue to 0 
  !RET 12         ; return from DllEntryPoint 

 Else 

  ProcedureReturn ; return normally 

 EndIf 
 
EndProcedure

"File no found : PureBasic.dll"

dll in apppath ?

Verfasst: **03.06.2008 13:54**

Yes, and i declare her like this :

Code: Alles auswählen

Private Declare Function Kcc Lib "PureBasic.dll" (ByVal Session As String) As Long

If i remove the code of FREAK, the DLL works fine in VB and in pb

Then "File not found" is probably a generic error that VB displays when the dll cannot be loaded.
This is what you want, isn't it ? If you prevent the dll from loading, VB has to display some kind of error.

Hello FREAK, thanks to help me

It's a normal comportement of VB for you !!!
But it's a more big mule that me, because the DLL is here, she just no be loaded.
This mule said "no DLL", if he said "The DLL can not be loaded" that is a good error message, but he said "no DLL". what a mule....

Perhaps, i must manage this error in VB ???

This VB, more i programing PB, more i hate him

Verfasst: **03.06.2008 17:34**

I read the VB doc, and see :
VB can not manage error DLL

I search again

I have some news about VB and the library, thank RENFIELD a VB programer

He said me, to use the API "LoadLibrary" before call the function in the DLL
And that's right, it's works

I give in this forum this information, if a crazy like me use a day this fonction

Thanks you very much at all
