Custom Programs

Hi, I have a custom program writen in VB6 that works without a problem in AutoCad 2002. But if I run the program in AutoCad 2005 it stop in the code and I get a runtime error.

frmProgress.ProgressBar1.Value = 27

Application.Update
Application.ZoomExtents <<<stops here
Unload frmProgress
Unload frmDrawShed

This is the error message I get . Run-time error '-2145320932 (8021001c)':AutoCAD Main window is invisible.
Any help would be appreciated. I have support subscription with autodesk. This is what they suggested which wasn't much help (Thank you for choosing Autodesk Subscription.

I am sorry for not being able to help you much on this occasion.

Hope the above information helps.)
This makes me wounder why I paid for support in the first place. If anyone can help me it would be much appreciated.

 

Hi Matthew,

In addition, they could have told you that you can join the Autodesk
Developers Network where you can get support for things like this. (Cost
may be prohibitive for an individual.)

However, their advice to come here is sensible as there are many users here
who will try to help.

Most likely you will find that your VB code has a reference to the R2000
format drawing objects.

In later versions of AutoCAD you will need a reference to the R2004 format
drawing objects.

Open your VB project and check the references. Compile the file under a
suitable name to distinguish it from the original.

Do you have an active document at the time of the zoom ??

 

Hi Jorge, no at the time the program is run all that is active is AutoCad 2005, the form from the program, and a progress bar. I have tried unloading the form and progress bar before zooming but it get the error.

 

Hi Laurie, do you mean in the visual basic editor, tools menu, reference I had a look there but I couldn't find R2000
format drawing objects or R2004 format drawing objects. In the list. Is this the spot you are talking about I'm still learning. Thanks.

 

Hi Laurie, had alook at you companys web site it mentions training just woundering what AutoCad and Visual basic training courses you have in Melbourne ?

 

What Jorge meant was is there a drawing open. If no drawing is open, then
you can't do a zoom extents.

You also need to show more code. For example what is Application and how do
you set it? By default, Application is the program you are runnning which
would be your VB6 app [or are you really in VBA?]; Application would not be
AutoCAD.

Yes there is a drawing open after the program stops. you can zoom from the command line. I've posted more code I hope it helps.

Try this to see what happens.

Maybe ACAD is still busy when you issue the zoomextents
If so, a check for no activity (IsQuiescent = True) would be a good idea
before doing the zoom.

 

Hi Matthew,

We do a one day introduction to VBA course and a whole range of Land
Desktop, Civil Design, Survey, Civil 3D courses as well as training in our
own software.

Any further discussion on this is not appropriate in the public NG. Please
write to to get further details.

Melbourne ?

 

Hi, I removed the application.update and add the code before zoom but i still have the same problem it stops at zoomextents. Thanks for your help.

Matt.

 

Just to be sure, is the acad window visible at the time ??
Is the active document (dwg) visible??

 

BTW, have you tried making the acad windows the top window
using the system API call

Public Const SWP_NOMOVE = 2
Public Const SWP_NOSIZE = 1
Public Const FLAGS = SWP_NOMOVE Or SWP_NOSIZE
Public Const HWND_TOPMOST = -1
Public Const HWND_NOTOPMOST = -2

Declare Function SetWindowPos Lib "User32" _
(ByVal hwnd As Long, _
ByVal hWndInsertAfter As Long, _
ByVal x As Long, _
ByVal y As Long, _
ByVal cx As Long, _
ByVal cy As Long, _
ByVal wFlags As Long) As Long

SetWindowPos(hwnd, HWND_TOPMOST, 0, 0, 0, 0, FLAGS) before doing any zoom
???

 

I had a second look at the program reference you were right. I didn't see it the first time I looked. Feel pretty stupid anyway thanks a bunch.

Kind Regards,
Matt

 

Hi Matthew,

I had similar problems with several programs that I had written in Delphi. They ran fine in AutoCAD 2000 but would cause AutoCAD 2005 to throw and exception--usually before/after Saves, Regens, and Zooms. It appears that the out-of-process automation controller is getting ahead of AutoCAD. I added code to check the state of AutoCAD before/after Saves, Regens, and Zooms and that seems to have eliminated the freeze-ups.

Here's my code in Delphi and a VB version (which I didn't test):
[pre]
// Delphi
procedure WaitForAcad( const Acad : AcadApplication );
var
IsIdle : Boolean;
State : AcadState;
begin
State := Acad.GetAcadState;
IsIdle := False;
repeat
IsIdle := State.IsQuiescent;
until IsIdle;
end;

' Visual Basic
Public Sub WaitForAcad( Acad As AcadApplication )
Dim IsIdle As Boolean
Dim State As AcadState

State = Application.GetAcadState;
IsIdle = False;
Do
IsIdle = State.IsQuiescent;
Loop Until IsIdle;
End Sub

' In your code...
WaitForAcad Application
Application.ZoomExtents
[/pre]

There may be a better method of resolving this problem but the above solution works and got my users up and running for the time being.

 

Hi, Thanks for the code I wil give it a try. I've had some luck with changing the program references in some of my programs to get them going.Thanks.

Matt.
