In a C# winform app. I'm writing a Clipboard log manager that logs test to a log file, (everytime a Ctrl+c/x is pressed the copied/cut text gets appended to the file)
I also did the same for images, that is, if you press "prtScreen", the screen shot you took will also go to a folder.
I do that by using a timer, inside I have something which 'looks' like this:
if (Clipboard.ContainsImage())
{
if (IsClipboardUpdated())
{
LogData();
UpdateLastClipboardData();
}
}
This is how the rest of the methods look like:
public void UpdateLastClipboardData()
{
// ... other updates
LastClipboardImage = Clipboard.GetImage();
}
// This is how I determine if there's a new image in the clipboard...
public bool IsClipboardUpdated()
{
return (LastClipboardImage != Clipboard.GetImage());
}
public void LogData()
{
Clipboard.GetImage().Save(ImagesLogFolder + "\\Image" + now_hours + "_" + now_mins + "_" + now_secs + ".jpg");
}
The problem is: inside the update method, "LastClipboardImage != Clipboard.GetImage()" is always returning true!
I even did the following inside the update method:
Image img1 = Clipboard.GetImage();
Image img2 = Clipboard.GetImage();
Image img3 = img2;
bool b1 = img1 == img2; // this returned false. WHY??
bool b2 = img3 == img2; // this returned true. Makes sense.
Please help, the comparison isn't working... why?
