OLE with byref sample (SOLVED)

[toninhofwi]

Hi friends,

Anybody know if there are example of default XP OLE components that works by reference ?

Something like:

---cut---
local a1, a2
oOle = CreateOle()
oOle:Test( @a1, @a2 )
---cut---

The sample is needed to fix a bug in Harbour OLE.

Thanks and Best Regards,

Toninho.

Antonio, do you have a sample please?

Viktor is asking me...

Toninho.

Toninho,

There are lots of examples for ole auto in these forums if you make a search for CreateObject.

But right now I can not remember any example that uses a parameter by reference

I´ve same problem...

how solve it ?

we can change source of xharbour ?

[Antonio Linares]

It has to be reported to the Harbour and xHarbour developers list (both).

Usually a test example (without using FWH) is required in order to check the problem and solve it.

Antonio tu poderia usar meu exemplo como referencia a este problema,
yo no consegui passar p/ CreateObjecto pero tu pode hacer isto abaixo segue lo exemplo:

Code: Select all

#include "fivewin.ch"
function main()
 public oWnd,oCommandbar,oToolA
 public Left:=Top:=Right:=Bottom:=0
 define window ownd

  oCommandBar:= TOleWevent():New("Codejock.CommandBars.13.0.0",Ownd)
   oCommandBar:AttachToWindow( oWnd:hWnd )
   cToolA:=oCommandBar:Add("ToolBar", 0)
   cToolA:GetWindowRect( @Left, @Top, @Right, @Bottom )  // GPF
   // Gpf yet here  
    MsgInfo(Left)
    MsgInfo(Top)
    MsgInfo(Right)
    MsgInfo(Bottom)

activate window ownd
return

Lailton,

You have to post an example to the Harbour and xHarbour developer list that does not use FWH and does not use a commercial ActiveX. You must use a Windows own ActiveX so other developers can test it.

No FWH, no CodeJock, got it ?

[lailton.webmaster]

Toninho,

that activeX you to be using ? can send to antonio ?

Antonio,

if Toninho don´t have it, so think that us need create something in VB
to send for they

I will try create it in Visual Basic a ocx.

Thanks

Hi Antonio,

I posted this message in harbour dev list, but Viktor can't fix it because my sample need register a DLL...

Please download this: http://www.fwi.com.br/nfe.zip.

You need dotnetfx.exe 2.0 or above installed, and you need register dll, because is OLE. There
are a registraDLL.bat file in that package.

to test:

--cut---
local oOle, nRet := 0, QtdErros := 0, Mensagem := ""
oOle = Win_OleCreateObject( "NFe_Util_PL005a.Util" )
oOle:ValidaXMLXHarbour( "", 1, @Mensagem, @QtdErros, @nRet )
? Mensagem, QtdErros, nRet
---cut---

The result NEED be:

---cut---
Erro: Arquivo de Schema Inexistente
0
3
---cut---


Best regards,

Toninho.

* harbour/contrib/hbwin/olecore.c
! fixed memory leak in PutParams()
! fixed parameters order in PutParams()
! fixed possible GPF due calling VariantClear() without VariantInit()
for C stack VARIANT item.
! fixed reverted #if condition - VT_I8 was not supported
+ implemented passing parameters by reference
Not tested at all - I do not have Windows and I'm not familiar
with OLE code/servers. I hope that Windows users can test it
and it Windows developers can update this code if necessary.

What i need change to use in xharbour ?

you can provide a sample toninho with it solved ?

thanks

[toninhofwi]

Hi Lailton.

I´m currently using Harbour, but xharbour works with OLE by reference too.

Do you have latest FWH ? There are a way to you test with Harbour to compare results ?

Regards,

Toninho.

[lailton.webmaster]

Hi Toninho,

I have fivewin 902

i have this problem and i dont know how solve it.

thanks

[toninhofwi]

Lailton, please do a test with Harbour.

The problem that I posted here is for pure OLE, without ActiveX, but Harbour ActiveX as implemented in the same way, so maybe it can work for you.

Sorry, but I can´t test it in XHarbour for while.

Regards,

Toninho.

No Problem TOninho thanks

I have too this problem, but i´m using Activex too, when i send for ref
give-me erro. i no use harbour.
