1. EuCOM 2.08 + WinXP Pro SP3

Hi,

Is anybody using Euphoria with WinXP PRO SP3... specifically SP3?
And worked with Eu v3.1 + win32lib v0.70.19 + EuCom 2.08 on it?

I have the following scenario at my place....

Till 3 weeks back, I had WinXP PRO SP2 + Eu v3.1 + Win32lib v.70.19 + EuCom v2.08 on my laptop working fine for last 4 years, when WinXP files got corrupt and I had to reinstall WinXP (with sony pre-install recovery cd) going back to year 2005 stage.

As I had to anyway get the latest updates for SP2, I decided to slipstream SP3 from my original i386 folder using RyanVM Integrator update packs and nLite. Everything went accordingly, and I could create an iso image which I installed on a VritualbOx instance/machine. I also installed all required Euphoria and other applications for my project.

Everything worked fine including IDE, untill I executed my main project which uses EuCom 2.08 for accessing third party ActiveX controls.

Now, the ActiveX control (present in c:\windows\system32 folder) Regiatration process fails with 0 (zero) as return code, which was working before the reinstall.

I tried using regsvr32 for registering same controls and they Displayed "DllRegiterServer in [control-name] succeeded" message. Also, my application setup installer program also deosn't generate any error while registering these controls.

Thinking that it could be SP3, I tried to execute same project on physical machine (with SP2), but getting the same result. I regenerated the wrapper using Tbrowse.exw, tried under both SP2 and SP3 environment, without any success.

But the sgrid.ocx provided with EuCom demo works just fine, I can register/unregister it using the same code in my program.
Also, the original demo program which was provided with third party ActiveX controls also works fine.

Following is the code -

atom RSVR32  
-- add various ocx names and their corresponding ids from respective ew files  
-- to following 2 sequences  
ocxnm1 = {"OneWayX.ocx", "OneWaySerialX.ocx"}  
ocxnm2 = {OneWay_clsid_ix, OneWaySerial_clsid_ix}  
--  
RSVR32 = 0  
-------------------------------------------------------------------  
--  Window SynInit -- Info Window  
global constant SynInit = createEx( Window, "Syndicate Setup", 0, 0, 0, 220, 64, 
			 {WS_BORDER, WS_CLIPSIBLINGS}, {WS_EX_DLGMODALFRAME} ), 
		LTextInit = createEx( CText, "Setting up File....", SynInit, 4, 4, 204, 24, 0, 0 )  
setVisible( SynInit, w32False )  
----------------------------------------------------------------------------  
--  
-- register and open ocx  
--  
global function reg_ocx(sequence regnm, atom clsid_ix)  
	RSVR32 = create_com_object( clsid_ix )  
	-- Try to register ocx if it didn't create properly  
	if not RSVR32 then  
		setText(SynInit, appName & " OCX Setup")  
		setText(LTextInit, "Registering " & regnm & " ...")  
		openWindow(SynInit, Normal)  
		setVisible(SynInit, w32True)  
    	        RSVR32 = open_dll( regnm )  
    	        RSVR32 = define_c_proc( RSVR32, "DllRegisterServer", {} )  
    	        c_proc( RSVR32, {} )  
		RSVR32 = create_com_object( clsid_ix )  
		sleep(2)  
		setVisible(SynInit, w32False)  
		closeWindow(SynInit)  
	else  
--		void = message_box("Already Registered!", regnm & " Msg", MB_ICONINFORMATION)  
		return RSVR32  
	end if  
	if not RSVR32 then  
		void = message_box(sprintf("Registration error : %d", {RSVR32}), regnm & " Msg", MB_ICONERROR)  
		abort(1)  
	else  
--		void = message_box("Registered successfully!", regnm & " Msg", MB_ICONINFORMATION)  
	end if  
	return RSVR32  
end function  
--  
-- unregister ocx  
--  
global procedure unreg_ocx(sequence regnm, atom clsid_ix)  
	RSVR32 = create_com_object( clsid_ix )  
	-- Try to unregister already registered ocx  
	if RSVR32 then  
		setText(SynInit, appName & " OCX Setup")  
		setText(LTextInit, "Unregistering " & regnm & " ...")  
		openWindow(SynInit, Normal)  
		setVisible(SynInit, w32True)  
		RSVR32 = open_dll( regnm )  
		RSVR32 = define_c_proc( RSVR32, "DllUnregisterServer", {} )  
		c_proc( RSVR32, {} )  
		RSVR32 = create_com_object( clsid_ix )  
		sleep(2)  
		setVisible(SynInit, w32False)  
		closeWindow(SynInit)  
	else  
--		void = message_box("NOT Registered yet!", regnm & " Msg", MB_ICONINFORMATION)  
		return  
	end if  
	if not RSVR32 then  
		void = message_box(sprintf("Unregistration error : %d",{RSVR32}), regnm & " Msg", MB_ICONERROR)  
		abort(1) 
	else 
--		void = message_box("Unregistered successfully!", regnm & " Msg", MB_ICONINFORMATION) 
	end if 
end procedure 

Any help is appreciated.

Thanks & Regards,
Rad.

Hi Matt,

The original test program provided with the activex control works fine with both
WinXP Pro SP2 and SP3 on my machine, and as expected the author confirmed the same.
At present I am back to WinXP Pro SP2 with latest updates (almost all).

I used com_err_out(1) and got the following display:

CoCreateInstance Error: 80040154
80040154: Unknown error
CoCreateInstance Error: 80040112
80040112: Unknown error

When I tried to register it again, I got:

CoCreateInstance Error: 80040112
80040112: Unknown error
CoCreateInstance Error: 80040112
80040112: Unknown error

I have this EMSA Register Dll Tool from the web, which displays the current
registration status (Yes/No) of specified Dll/Ocx file and allows to register/unregister
the same. I tried registering/unregistering my control with this utility and it
worked fine. Using this utility, I unregistered my ocx.
The registration status was set to "No".
And then executed my program.

My program got aborted with return code 0 (zero).
I went back to EMSA utility, and found that the ocx was in fact had got registered.
The registration status was "Yes".
But somehow the EuCOM return code is always coming back as zero.

Also, even after externally registering the ocx, the procedure mentioned
in the first post does not detect the existing registration and tries to register
the same ocx, giving the zero return code.

Because now I have a reinstalled WinXP, may be it is some missing windows
file which EuCOM requires? Can you please list the windows files that EuCOM
requires to run properly?

Thanks & Regards,
Rad.

Hi Matt,

As I will be distributing only ocx file with my application, I hadn't installed the ocx application on my machine, as it won't be on my client's machine.

After installing the ocx application and including its base folder in the PATH, EuCOM started to recognize ocx as registered. (The ocx was registered by the ocx application while installing it in the base folder.)

The difference between the ocx base folder and the folder where I have copied ocx file for my application, is one .lic file with ocx name.

I unregistered the ocx externally, and keeping the path same as ocx base folder with .lic file, tried to register it through my application using EuCOM. But got the same error status 0.

Again, I registered the ocx externally, and this time EuCOM picked up the registration correctly.

I put up the same Q for the ocx developer and got the following answer:
-------------------
It seems like it can't find the .lic file. Normally you need to have the corresponding .lic file present in the same directory as the .ocx in order to use it in a design environment (but not in a runtime environment).

When ocx is installed, the .lic file is in the same directory where the .ocx file is, but if you move it and register it somewhere else, the .lic file must be copied there too.

Microsoft's idea is that it provides a simple license protection for ActiveX controls, because normally the .lic file won't be distributed along with the ocx, as it's not required in a runtime environment. That means users can't just use the copy of the control which is distributed with some other application in their own applications.

---

Looks like there is an issue with this .lic file as indicated by code 80040112.
I have the .lic file in the required folder, but still EuCOM comes back with 0 status code.

How does EuCOM handle .lic file?

Thanks & Regards,
Rad.

Hi Matt,

I had put up a query with ocx developer regarding a dummy activex control for testing purpose and got the following reply:

I suggest that you rather use the trial version of the .ocx,
which you can download from my site. The only difference from the registered
version is that it has a random popup message every few function calls.

The activex control download site is http://www.atma-software.com
The application file name is 1Way and size is around 1 MB.

Thanks & Regards,
Rad.

No, sorry, haven't had much time for euphoria lately. Have you tried doing anything with those functions I mentioned before?

Matt

CoGetClassObject = define_c_func( ole32, "CoGetClassObject",\\ 
	{ C_POINTER, C_INT, C_POINTER, C_POINTER, C_POINTER }, C_LONG), 

	mset = w32new_memset() 
	ppv = w32acquire_mem( mset, 4 ) 
	rclsid = w32acquire_mem( mset, clsid_table[CLSID_BYTES][clsid_ix] ) 
	riid = w32acquire_mem( mset, iid_table[IID_BYTES][1] ) 
 
	ok = c_func( CoCreateInstance, { rclsid, 0 , 5, riid, ppv } ) 
 
	if not ok then 
		obj_ix = ref_com_object( clsid_ix, peek4u(ppv) ) 
	else 
		err:print_com_error( sprintf( "CoCreateInstance Error: %x\n",ok)) 
		err:com_error( ok ) 
		obj_ix = 0 
	end if

Hi,

Please can anybody guide me regarding incorporating relevant EuCOM functions in the existing code?
