Adobe Reader via VB6...UGH 1

[Chad123]

Hi,

I have recently noticed something really weird with the Adobe Reader on a Windows 2000 Terminal server. If I log onto the console, everything is fine and works. However, if I login using a terminal session, I can open 1 pdf document fine. It is when I open up the second one, it seems to freeze and won't respond anymore.

The whole point to this is that we have an application that will create a pdf and then we bring it into view. Now when you try to load another pdf into the viewer (Adobe Reader), it gives an error message:
The instruction at "0x77fcb2a7" referenced memory at "0x00720045". The memory could not be "read".

Then:
The instruction at "0x77fcb03d" referenced memory at "0x00000000". The memory could not be "written"

Now, this will only happen in a terminal session. Now I can get the reader to freeze sometimes opening it by itself by opening more then 1 document at the same time.

FYI: We use the Amyuni PDF Creater to make our PDFs.
Adobe Reader: 5.0.5 (same issues as 5.0.1). Visual Studio 6.0 used for Application creation.

Anyone have any suggestions?

Are you using Reader, or PDF.OCx, or ActiveView?

Thanx for the info, however, I forgot to mention one thing... This was working for months upon months, but now all of a sudden I have encountered these errors. It is not a printer issue, and it is not a rights issue either...

Have you tried updating to Reader 5.1. Could be that there is a corruption in the Reader, also did you change the Terminal Server Mode? May be you need to include a Manifest for Reader.

 

[Chad123]

I have tried updating Adobe but that did not help, and I tried both modes!

I am reinstalling SP3 to see if that helps. Suppose it may just be my code that is pouched? (However, I have not made ANY modifications to that section)

hmmmmm

 

[rorubin]

Hold on. Do you shell out?

 

[Chad123]

What exactly do you mean by shell Out?

 

[rorubin]

Do you do this Shell("adobe exe " & "your.pdf&quot

 

[Chad123]

No, not for the viewer/pdf.

 

[rorubin]

How do you launch the Reader? Are you using Acrobat Exchange for building not PDF's?

 

[Chad123]

We use an actual API function call. We use an Adobe product to create the pdf, but I ma not sure which one to be honost with you.

Why? Whatcha thinkin?

 

[Chad123]

OK, I did some digging, and we use pdf.ocx to open the pdf's. (I did not design this part, I am just fixing it...)

Any ideas?

 

[rorubin]

Okay the PDF.OCX is not Supported by Adobe in the manner in which you are using. You need to download the SDK, and take a look at the example ActiveView. The error:
The instruction at "0x77fcb03d" referenced memory at "0x00000000". The memory could not be "written"

Is a problem in your exe, and I have seen it before which was why I initially asked.

Try it using the ActiveView Example. Please note that VB5Programmer led me to this in a prior thread I simply have no idea where that thread is anymore. Anyway it solved alot of my problems and may solve yours.
