Hi everyone,

I am trying to use 1way activex in a PB program via ComatePlus and I'm having problems with setting up the calls properly.

1way is an ActiveX control which provides a way to create a time-limited trial version of an application. I had used it before in VB
The way it's supposed to be used in the app is as follows:
1) instantiate the activex in the app
2) call GetData(AppID) to retrieve registration info and set AppStatus and AppDaysLeft properties
3) check AppStatus

if AppStatus = 0, data for app had not been setup yet so a call to SetData(AppID, NewAppStatus, NewAppDaysLeft) will have to be made

if AppStatus = 1, app is still within the trial period, display days left in trial and let the app continue to run

if AppStatus = 2, app is expired - show nag screen, disable some functions in the app or exit

if AppStatus = 3, app is registered, let the app continue to run

I was able to do step 1 but could not get pass step 2 - here is the relevant portion of the code I'm working with:

Code: Select all


IncludeFile "COMatePLUS.pbi"

DataSection
    OCXsourceStart:
      IncludeBinary "OneWayX.ocx"
    OCXsourceEnd:
EndDataSection 

Enumeration
	#holder_0
EndEnumeration

If OpenWindow(0, #PB_Ignore, #PB_Ignore, 300, 150, "OneWay Test", #PB_Window_SystemMenu|#PB_Window_Invisible)
	;I'm making a copy of the ocx and registering it before using it
	x = CreateFile(1, GetCurrentDirectory() + "OneWayX.ocx")
	If x > 0
		WriteData(1, ?OCXsourceStart, ?OCXsourceEnd-?OCXsourceStart)
		CloseFile(1)
	EndIf
	ocxFile.s = "/s " + Chr(34) + GetTemporaryDirectory() + "OneWayX.ocx" + Chr(34)
	RunProgram("regsvr32 ", ocxFile, "")
	
	Object_1Way.COMateObject
	ContainerGadget(#holder_0, 0, 10, 35, 35)
	   Object_1Way = COMate_CreateActiveXControl(0, 0, 35, 35, "OneWayX.OneWay")	;"{2BF78C6C-FB88-4F6C-87AB-C6E7F4CE6575}")	
	   Debug "container created...."
		Debug "Object_1Way = " + Str(Object_1Way)
		Debug "error code = " + Str(COMate_GetLastErrorCode())
		Debug "error desc = " + COMate_GetLastErrorDescription()
		Debug "=============================="
	CloseGadgetList()
	HideGadget(#holder_0, 1)
	;=========================================
	; A                                     A
	; |                                     |	
	; +---------  OKAY UP TO HERE  ---------+
	;
	;=========================================
	;
	; +--------  PROBLEM DOWN HERE  --------+
	; |                                     |
	; V                                     V
	;=========================================
	If Object_1Way 	
		appId.s = "testApp"		
		OneWayGetDataCall.s = "GetData('" + appId + "')"    ;<==== how should the invocation 
		Object_1Way\Invoke(OneWayGetDataCall)               ;<==== to GetData() look like
		Debug OneWayGetDataCall
		Debug "error code = " + Str(COMate_GetLastErrorCode())
		Debug "error desc = " + COMate_GetLastErrorDescription()
	EndIf
EndIf

Based on the 1way help file, the GetData function take in a string and returns a boolean

Boolean GetData(AppID)
Parameters
AppID : string
Return Value
GetData returns True if it was able to retrieve the saved data correctly:
GetData returns False if there was an error condition and the data could not be retrieved correctly

If I run the code above using the function definition from the 1way help file, I get these results:

Code: Select all

container created....
Object_1Way = 36052624
error code = 0
error desc = Okay.
==============================
GetData('testApp')
error code = -2147352570
error desc = Method/property not supported by this object.

When I used the TypeLib Explorer to find the function, I see the function listed as:

Code: Select all

    GetData(a, b)
    ; a BYVAL AppID INTEGER (#VT_BSTR)
    ; b BYREF Value BYTE (#VT_BOOL)

So now, how should I structure the function call that I wanted to make?

If needed, a trial version of the ocx can be downloaded from here: http://atma-software.com/1way/1WaySetup.exe
