In an app that I am developing.
I am using following code to retrieve data from web service.
HTTPRequest("http://xxxx.xxx/" + gsID) sResult is Buffer = HTTPGetResult(httpResult) This will return a JSON string which will contain a list of JPG files.
Now my software will have to download each JPG file and save them on the storage media of phone and then show the same as slide show to user.
I tried to save the file with this code:
FileNum = fOpen(fn,foCreate) fWrite(FileNum,sFileData) fClose(FileNum) But the data save is corrupted and does not open up on any image viewer.
What wrong am I doing here?
TIA

Hi
1. We don't know how you got the data in the first place, so there may be a problem there
2. you are using what seems to be a string (sfiledata) to contain the image data (BINARY!). Use a buffer instead
3. Don't bother with fopen and such. A simple fSaveBuffer will do
Best regards |
