Howdy Mr. Pikman!

Here is a description of the environment that I am working in.

I work on a research project under the anacronym ALERT standing for Advanced Law Enforcement Response Technology. If you would like to learn more about this project you are welcome to go to our web page at:
http://alert.tamu.edu.

My task is to produce the software applictaions that will run on the officers workstation. These include law enforcement information(LEI) queries, gps mapping, e-messaging, and last but not least databases. Of these tasks I am creating the LEI and databases and integrating the other applications.

Citation or any relevant data is entered on a handheld computer and saved as an access database and seperate .bmp images. Digital images are also captured from a Kodack camera and associated with the record. The images are captured signature images and notes that the officer may make. These files are transfered via wireless communications to the vehicle. Then the vehicle sends that information back to the base computer where I import the information, images and all. The need arose to export the images for legal and insurance purposes thus I need to extract select images.

While they are in one of my forms viewing the images they may hit a button that will bring up a save as prompt. When they decide upon a filename then hit save as, I call the code that you have provided. Unfortunately I have not had any success at opening the .fpt file. After the file is saved 'filename.fpt' I rename it to 'filename.bmp' but am not able to open it with paintbrush, etc.

I hope that this is enough background information for you. Oh, my programming experience is as follows:
2 years MS Access Database - single user application.
1 year MS Visual Basic
2 months VFP.

Here again is the code snippet that I am using.

SELECT citations
SET ORDER TO citation_n
CitationNumber = INT(VAL(CitationNumber))
SEEK CitationNumber
COPY FIELD citation_images_signature NEXT 1 TO &Filename

Once again thank you for your time and advice, it is nice to know that there are people who help struggling programmers.
