Can't Display Image File in Access Runtime on Some Windows 7 Systems
I have an Access 97 runtine application with about 800 users. (I know it's ancient ... I am currently re-writing / updating it, but that will take a few more months.)
One feature allows users to link to pictures in the database. The data table doesn't store the actual picture object; it stores the path to the picture (stored on the user's hard drive). The UI form allows the user to view the picture(s) and print as well.
This works as desired for the majority of users, but a handful of users with Windows 7 machines can't use this feature. When they try to add a picture, they get an error that the application doesn't support the file format, even though they are working with the standard JPG, GIF, or BMP formats.
To be clear, this is only happening to a few Win7 users. Many other Win7 users have no issue with the picture feature. I have two Win7 machines here and it works great on both, which of course makes it difficult for me to troubleshoot an issue that I can't reproduce.
I had a similar issue with this same application a number of years ago with Windows XP ... most users had no problem but a few received the "doesn't support this format" error. I was able to resolve that by creating a quick exe patch that set the Windows graphics filters on their machines ... they would run that once and then all would be fine. Running that exe patch on the Win 7 machines has not resolved the issue, and I haven't turned up any helpful research on graphics filters in Win 7.
I worked with one user that was experiencing this issue and I remotely accessed his PC and compared relevant registry keys to those in my Win7 machine and found no differences.
I'm including the code for the UI form here; the first sub is used to display the picture and the second sub allows the user to browse for a picture file and then stores the path to that picture in the table.
I would appreciate any suggestions to resolve this - whether it involves changing the code or something else that the user needs to do.
Thanks in advance for any advice!

Just some notes...
As a general rule, I don't "Call" the current event. (like you are doing in your button click code)
I let it trigger on its own.
If you need this "Image code", then put it in its own sub and Call it from the current event.
This is because the current event can also contain other code that you may not want to run, if you only need to display an image.
Then in your Button _Click code I would call this new sub, (not the Current Event)
Something like this:
Private Sub DisplayImage()
On Error Resume Next
If IsNull(Me.PicPath) = False Then
Me.imgPic.Picture = Me.PicPath
Else
Me.imgPic.Picture = ""
End If
Me.Refresh
End sub
Private Sub Form_Current()

Thanks again for the info. I have read the material / links you provided and it sure seems to be related to the issue some of my customers are having.
However, I'm a bit confused with the "Microsoft-speak" in the KB articles. Just to clarify ... is the security patch causing the problem, or is it intended to resolve the problem?
If it is causing the problem, are they then saying that users have to manually edit their registry keys (thus creating a security hole) in order to use graphic files in Office programs? Yikes!
Sorry to bug you, but I just want to make sure I understand this before making my customers (who are very basic PC-users, not experts at all) jump through hoops so we can test this.
Thanks!

Microsoft's patch disabled the graphics filters to alleviate a threat to Windows OS security (malicious code could be delivered behind an image). Thus the patch created the problem you are having.
Yes, changing the registry keys would have to be done on each machine having the problem. However, there are scripts that will automate the changes to the registry keys. Try googling on "VB code to change the windows registry keys".

Hello -
I have an update on this issue, which unfortunately is not resolved. I've connected with two customers who are experiencing the problem, and it seems the MS Security Patch referenced above is not the cause. Both of them had the problem before December, when the patch was released.
Does any one have any other suggestions?
Thanks!

Hi puppydogbuddy -
I reviewed the KB article you referenced. Although I don't use a separate function as is shown in the article, I am using the same assignment method to display the image:
ControlName.Picture = FilePathFileName
Thanks anyway ...
