Interface Generator 1.0 - Get it!

[techjunkie]

[quote="Num3"]I've been messing with VB ActiveX controls and they work just fine [quote]

Same goes for me... Beautiful work!! Now we are talking...

Thank you! Great stuff!!!!!

[Edwin Knoppert]

Do you mean controls?
Do you have a simple example?

Thanks,

[ricardo]

@Num3 Thanks.

The file requester should keep the last directory you went to...

You are right. I'm aware that I could do something more on the GUI side of the Interface Generator. Use a Menu and/or Toolbar... I thought it would be useful to publish the tool now, so it can be used. I'll work on improvement from now. Any other suggestions?

I was way from the forums sometime, sorry if i make a stupid question

I make the interface for the MSscript.ocx

Code: Select all

; Interface generated by Interface Generator 1.0, Date 05/31/2004 

; MSScriptControl, Microsoft Script Control 1.0

; Enumerations

Enumeration ; ScriptControlStates
  #Initialized = 0
  #Connected = 1
EndEnumeration

; DispInterfaces

Interface IScriptProcedure Extends IDispatch
  get_Name(a)

  get_HasReturnValue(a)

EndInterface

  AddObject(a,b,c)
  Reset()

EndInterface

Which is the next step to be able to use it in PB?

As described in the documentation you can download COMLIB from http://home.planet.nl/~aXend/purebasic/COMLIB_demo.zip. This LIB contains the function

Code: Select all

object = CreateObject(ProgID)

After that you can do

Code: Select all

object\function()

as found in the Interface.

You have to find the meaning of the methods and properties in the manuals of MSScript. I can't help you with that.

[Edwin Knoppert]

Is it possible to have visible controls?

Thanks for your answers!

One more question: where did i get the ProgID?

---

In this case the object\function() could be, per example, object\AddCode()?

Your application and your library seams very good!!

Thanks in advance for your help

[ricardo]

Doing this don't work, what im doing wrong?

Code: Select all

IncludeFile "msscript interface.pb" ;the interface i show in other post here
Debug object.IScriptControl = CreateObject("MSScriptControl.ScriptControl.1")
Debug object\_AboutBox()

Thanks in advance

[aXend]

I've been playing with ScriptControl. What you did is correct, except for the "Debug object\_AboutBox()". You should leave the Debug and code object\_AboutBox(). This works!

See my test code.

Code: Select all

IncludeFile "MSScriptControl.pb" ; the Interface file

Structure SAFEARRAYBOUND
   cElements.l;   // The number of elements in the dimension
   lLbound.l;     // Lowerbound of the dimension
EndStructure

Structure SAFEARRAY
   cDims.w;       // Count of dimensions in this array.
   fFeatures.w;   // Flags used by the SafeArray routines documented below.
   cbElements.l;  // Size of an element of the array. Does not include size of pointed-To Data.
   cLocks.l;      // Number of times the array has been locked without corresponding unlock.
   pvData.l;      // Pointer to the data.
   rgsabound.SAFEARRAYBOUND[1] ;      // One bound for each dimension.
EndStructure

Very nice example!!

I understand most of it at first time, the rest will study it with care.

Thanks a lot for the example and for your hard work to bring this powerfull option to PB!

[ricardo]

A very fast and direct example:

Code: Select all

IncludeFile "msscript interface.pb" ;the one showed here before
object.IScriptControl = CreateObject("MSScriptControl.ScriptControl.1")
object\_AboutBox()
object\put_Language(Ansi2Uni("vbscript"))
object\ExecuteStatement(Ansi2Uni("msgbox " + Chr(34) + "hello msscript from PB" + Chr(34)))
object\ExecuteStatement(Ansi2Uni("Value = (3*3)+100:MsgBox Value"))
ReleaseObject(object)

Have fun!

[ricardo]

One more question.

What to do when i know there are some 'elements' that are not showed in the interface?
I found this same problem in VB, but there no matter if the elements are not listed, they work.

One example:

If i create the interface for "Shell.Application" i know i can work with all this

Code: Select all

Set oWeb = CreateObject("Shell.Application")
Set Web = Web.Windows

Web.count
Web.Item(i).Document

But in the interface i cant see, per example, item().document

As i said before, this same thing happends when using VB, the intelisense of VB or the object examination DONT show document and many others, but they work if i put it there... in PB what can i done?

In this case:

1.- How can i do this:
Set oWeb = CreateObject("Shell.Application")
Set Web = Web.Windows

2.- Then how can access to
Web. count
Web, Item(i).Document... etc

Because many Activex dont display for some reason all they properties, methods, etc. with the interface but they are there and could be used.

Thanks in advance

[aXend]

You said this worked with VB, but I tested it and it didn't.

Set oWeb = CreateObject("Shell.Application")
Set Web = Web.Windows

Web.count
Web.Item(i).Document

First I had to change "Set Web = Web.Windows" to "Set Web = oWeb.Windows".
After that I got the message that "Document" was not a supported method or property with "Web.Item(i)...".

You can do the first three statements with the Interfaces. It would be something like this:

Code: Select all

oWeb.IShellDispatch  = CreateObject("Shell.Application")
oWeb\Windows(@Web.Folder3)
Web\Items(@WebItems.FolderItems3)
WebItems\get_Count(@count.l)

I didn't test this yet. I guess you'll have to rearrange the Interface file, because some interfaces refer to others and they're not in the order that PB wants to.

[EDIT] I found that some of the interfaces already exist in PB. I think we have to blame Fred for that...

[Fred]

Very handy tool, good work aXend !

[ricardo]

@aXend

I will try out tonight because want to find a way to go to deeper usages on this, is very interesant!


The Web.Item(i) not only have Document, but many others, in fact has more deeper 'levels': Web.Item(i).Document .All.Tags etc, etc.

That same thing i found in many Activex, that has much more than is listed on the interface. Need to find a way to use it in PB.

Thanks

I think you'll need to query using the IID for these interfaces.
I don't think it's useful though.
