runtime error -1(ffffffff)

[Transcend]

Hi there guys,

I'm a bit stuck. The scenario is there, I have a webbrowser control on a form and all it does is open up a picture when given a file location. Basically my users call up drawing records, and if a file location exists they can open up the picture. At the moment the way they close the form is just by clicking the little x at the top right of the form. However once I try to open up the 3rd or 4th picture I get the error

runtime error -1(ffffffff)
Method 'Show' of object 'frmDrawingImage' failed

and the program crashes.

However when I go into debug mode and hit debug here, then continue, the picture opens up fine!!
Any ideas??

Thanks in advance

I should add that i'm not opening up 4 different instances of the form - i'm closing the form then reopening it.

I'm just really stuck on this one! Should I be adding something to my form_unload event???

why not use the

on error goto Err:

Err:
exit sub Please pardon the grammar.
Not good in english.

In th Form_Unload event, be sure to Set all module level variables that contain object references to Nothing. I also would
Set formname = nothing
Also be sure that there are no references to the form or its controls elsewhere.

Put this in to see if the form is terminating.
Private Sub Form_Terminate()
' Do not reference any form or control properties.
Msgbox "terminated"
End Sub

If you do not get the message, the form is unloading the controls but not terminating. There is a difference. If the form does not terminate, module level variables will keep their values through the next Load.

Hi guys,

thanks for your replies, unfortunately nothing seemed to work!! I set EVERYTHING to nothing - and while I could just put an exit sub on an error occuring I'd rather not do this ... in the end I changed the way i was opening the drawing.

Instead of using the webbrowser control I now use the Shell command to open the drawing up in imaging preview

Haaa, Imaging Preview = Kodak/Wang Imaging controls (Image Edit to be more precise). So if you want to keep it in your own program....

Good Luck

Haha .. i didn't set it to imaging vb5prgrmr, it actually just opens up the drawings with whatever program the file is associated with

Most of the drawings are tif files and in my case the association was with imaging - if i change the file association a different program opens. We made it this way because they want the drawing to open outside the app - they have the option to edit it etc with another tool we created.

Thanks anyhow!
