I am trying a program that edit the existing exif image to to a newly one, but it seem that I don't have luck.

I extracted exif data in an image, this is the code:

Dim objExif As New ExifReader
Text2.Text = CommonDialog1.FileName
Dim txtExifInfo As String
If Text2.Text = "" Then
MsgBox ("please insert an image")
Else
objExif.Load (Text2.Text)
txtExifInfo = objExif.Tag(DateTimeOriginal)
Text1.Text = objExif.Tag(GpsLatitude)
Text3.Text = objExif.Tag(GpsLongitude)
Text4.Text = objExif.Tag(GPSInfo)
Text5.Text = objExif.Tag(DateTimeDigitized)
Text6.Text = objExif.Tag(Artist)

the textboxes are fill with this data, when I run the system was good, this is my problem, when I save the file, the exif data was lost (GPS Latitude and Longitude are lost the save image. another thing is the file size of the image gets bigger (from 28 Kb to 43 kb).

And One thing more, if the image doesn't have a gps lat and long, how can I edit the data and then save it to the property detail of the image.

any idea or code that might help to solve my problem will be gradually appreciated..

more thanks and more power to everyone!

I have a school project and I have no ideea where to start. I am a begginer and I need help understanding some things. The reason I am asking is because I can`t seem to find a straight answer to my problem no matter where I search for. Maybe I am asking the wrong question so I will try to describe my problem.

What I need to do is, to connect a java program to a database ( mysql ), and via GUI to display some records from a table.

Now, the table I am trying to display will be called "Flights", and has the next rows: "FlightiD","departure","destination","departureTime","arrivalTime","status",

The ideea is. that I need 2 GUI`s "Arrivals" and "Departures" that both take data from the table, and another one that allows me to modify the data into the table. Where do I find such a tutorial to help me do this? Is it possible for someone to show me pieces of code that will help me do this? How do I connect my java program to the database?

Of course the "Flights" table has data from other tables (company, Airport ).

I know it`s much to ask, but I need to start from somewhere and all the java tutorials I read and leaned, didn`t show me much about how I can do this.

This location path works nicely when reading the .XML file from my local machine where VS automatically chose the folder path from. The problem that I can see potentially would show itself once I deploy the app is that the deploy environment most probably wont have the same location path as my computer. I can imagine a good location for it but would really like to hear from people who actually have experience deploying XML files.

I do not want to create the XML on the fly owing to certain complexities in the file. So where should I put it so that I am guaranteed to find it on deploy ..

Somehow I have expanded the "quick find" window in visual c++ 2010 and

Any suggestions?

I have a program that gets .MID or .MIDI file volume.
midiOutGetVolume(0,&midvolme);
But I get MMSYSERROR_NODRIVER.
I run a program called driverdetective.
But I still can not get any MIDI drivers.

How do I get midi drivers on my 64 bit laptop with WINDOWS 8? ]]> Driver Development ROCKYCAT http://forums.codeguru.com/showthread.php?537101-Midi-driver
