What does not work there?

I can only assume when and what error there can be.
For instance, you're not disposing the of the , but the box itself on Line , which leads to an exception trying to access a disposed object.

Usually in WinForms you the image, by disposing it first, since it's a common memory leak mistake. Do it with something like this:

Try not to dispose the , but the object inside it.

im not sure whats not working, i disposed and set the picturebox to null so it must be what is set on the picturebox that is not resetting itself

somewhere between lines 73-88 I'd assume

So, what is your desired result?

that when i press the reset button i can change the images position without it keeping the original image

Okay, what do you mean by "change the images position"?

i made a way that the user can chose the x, y and size

and im trying to make it possible to reset the image cause of original icon is still there afterword

If you dispose and clear the picturebox's like I described it's fine.

SSpReeD If you dispose and clear the picturebox's `Image` like I described it's fine.

this is the latest code

SpReeD•4/11/24, 12:53 AM

There's no problem in and the image should save and clear the by adding on line 116.
After this, you can recreate an image and altering the x,y,width & height

I would guess your dialogs are holding the images hostage at this point

leowest•4/11/24, 6:08 AM

u dont dispose of a single dialog after u use them

Lleowest u dont dispose of a single dialog after u use them

FrostyioOP•4/11/24, 2:55 PM

i'll look into it

Lleowest u dont dispose of a single dialog after u use them

FrostyioOP•4/11/24, 9:32 PM

i disposed them, same result

FrostyioOP•4/11/24, 9:35 PM

ok i got some new results, when in my program if I open file dialogs again and chose the same images and generate it again (without using my reset button) it removes the old Image and adds the new one

FrostyioOP•4/11/24, 9:35 PM

but how come they keep my original image if I dont reopen file dialogs?

I did some testing, the problem is that it keeps the stream alive so its always modifying the stream your loading in memory that's why it never wipes it.

What u want to do is, use a Bitmap, and manipulate that bitmap.

For example:

And
