View 6 RepliesThe coding below is to retrieve the Raw Image Data from the Database and then write as a JPG image file. The problem is the image file (image.jpg) is "nothing" after file created. I guess there is something wrong in the following coding.
fs.Write(rawData, 0, fileSize)
No any runtime errors I can find, and I double check rawData (i.e. Buffer) contains data. But don't know why there is "nothing" inside the image (image.jpg).

View 7 RepliesWe have a winforms appliction that has to talk to an AS400. To do this we imported the IBM.Data.DB2.iSeries classes in the Winforms application and have IBM System I Access for Windows on our machines. It must have the System I Access or it will not talk to the AS/400. Everything works fine on my 64bit development machine. It also works fine on the client's 64bit machine. However when we attempt to install it on a 32bit machine we get a Bad Image format exception. We tried making just an x86 installer instead of any cpu but that did not work (same bad image exception).
