Last time I had a task to modify an image which is displayed on collection letter.
Just simple change.
The issue was, that nobody at company had original image.
Image was stored in one of Dynamics AX tables, so I had to take it out from there
Below you can find a simple code how to get this image and save it to some disk location
static void GetFile_PKI(Args _args)
{
CustCollectionLetterLine collectionLetterLine;
container image;
Bindata bin = new bindata();
str tmpImageHolder;
//I knew what RecId of that record is, so it's just simple select statement
select collectionLetterLine
where collectionLetterLine.recId == 5637144577;
//This is a table field where I have my image. Field is container type
image = collectionLetterLine.NotesLogo_PKI;
bin.setData(image);
// This will give me a string encoded as base64
tmpImageHolder = bin.base64Encode();
// I've chosen .jpg extension but in fact it does not matter
//You have to have a look on file header (for example in notepad) to get
//information what type of file it is.
AifUtil::saveBase64ToFile(@"C:\temp\test.jpg", tmpImageHolder);
}
