I have been searching for a way to extract images from access forms. A search on Google will nearly always point to OLEtoDisk. This software allows to export images stor
If you are looking to re-use the image in another access database (ie you lost the original image file, but want to use it elsewhere), a far easier method would be to import the object (form, report etc) into your new Access database using the External Data -> Access menu.
You can then just copy paste the image control where you want to use it...
Unfortunately copy/paste of image controls between Access databases doesnt work as you'd like.
The picture data is an EMF file, with a wrapper of 8 bytes. This is your routine modified to use the correct file extension
Public Function savePict(pImage As Access.Image)
Dim fname As String 'The name of the file to save the picture to
Dim iFileNum As Double
Dim bArray() As Byte, cArray() As Byte
Dim lngRet As Long
fname = Environ("Temp") + "\temp.emf" ' Destination file path
iFileNum = FreeFile 'The next free file from the file system
' Resize to hold entire PictureData prop
ReDim bArray(LenB(pImage.PictureData) - 1)
' Resize to hold the EMF wrapped in the PictureData prop
ReDim cArray(LenB(pImage.PictureData) - (1 + 8))
' Copy to our array
bArray = pImage.PictureData
For lngRet = 8 To UBound(cArray)
cArray(lngRet - 8) = bArray(lngRet)
Next
Open fname For Binary Access Write As iFileNum
'Write the byte array to the file
Put #iFileNum, , cArray
Close #iFileNum
End Function
Finally here is the code that worked as intended : Export a PNG image from a form's Image control.
Public Function savePict(pImage As Access.Image)
Dim fname As String 'The name of the file to save the picture to
fname = Environ("Temp") + "\temp.png" ' Destination file path
Dim iFileNum As Double
iFileNum = FreeFile 'The next free file from the file system
Dim pngImage As String 'Stores the image data as a string
pngImage = StrConv(pImage.PictureData, vbUnicode) 'Convert the byte array to a string
'Writes the string to the file
Open fname For Binary Access Write As iFileNum
Put #iFileNum, , pngImage
Close #iFileNum
End Function
