Save image from control of another window with button click.

bhavtosh sharma

I have a winform app with few controls that loads an image and a datagrid to enter data. Issue: I want to save that image from my winform app when I click a button.

So far Im able to find the source window handle in C# code but do not know how to find that control and save the image...

I know I have to use winapi methods but do not know which ones...

Kindly provide some input or a sample code. I have attached the sample screenshot!!

Thank you...

As you said, they have different exe and you want to capture the image, as in the screenshot the picturebox is scrollable, we can't capture that. Although, you can use Graphic.CopyFromScreen(..) function and for that you first need to capture the window followed by its title bar.

@Rajanikant Hawaldar & @Amit Gupta,
control.find is limited to within app, here it is about 2 different exes with winforms...
It is do something with winapi methods & automation testing like White framework or MS uai, I need some starting points to sort this issue.

In addition to what @Rajanikant Hawaldar said, you can also add a get/set property in your control to fetch the image and then save that image.

Hope this will make your work quite easy and have a good architecture for your control

Good Luck!!
