Great! Thanks CJ.

Been distracted with other part of the application.

This version still needs to write images back and forth to the local disk to load into ddoc, yuck.
Because of this the logic had to be changed for client/server.
This is fast without the server, but leaves something to be desired running on a server.

The %TestMode variable shows the pushing and popping the database back and forth between local/server.
I'm not sure if that is killing the performance.  I'll work on this more when time permits.
Switching between local and remote is now very safe, but not sure it is implemented well.

Need to investigate ddoc source or perhaps these links:

Hello,

Been thinking.

I normally read images from the SQLitening Database and place them on the Picture Control. Like this:


sPicture = slFN("Picture")
VD_IPictureBox_LoadImageByMem(hfrmDPRRegistrationForm, %ID_FRMDPRREGISTRATIONFORM_VD_IPICTUREBOX1, StrPtr(sPicture), Len(sPicture)) 


I wish I could just use it to place the image on DDOC. Is there anyway to use it with dpAddGraphic?

Best regards,

VD_IPictureBox_LoadImageByMem() is wrapper function for PwrDev.

Hello CJ,

I am thinking of storing the images in a disk file.

The thing is, I am printing a Picture and a Name on the same page and can't figure out how to correctly match the appropriate Picture with the Name if the images are stored in disk file. I intend printing multiple pages at a go using a BatchNo.

Any ideas? Thank you for your responses.

How about an index to the locations in the flat file with any captions, titles, date you need by using a Table

slexe "create Table if not exists LocateImageTable(key UNIQUE, StartByteColumn,LengthColumn)"

I guess this is in response to my last post before this.

Its a bit confusing. A flat file using a Table like in SQLite?

Associate the picture and name with the starting byte in the file.
The table used to be an index to the file can contain anything and even the image.
