How can I capture and take screenshots of all the browser tabs and not only windows ?

Question

This class identifies all minimized windows and take a snapshot (screenshot) of them. I want to take screenshots also of all the broswer for example chrome tabs windows that are open but not in the front. Same idea that it get now the minimized windows but
to get the screenshots of the broswer opened tabs ! What should I change in the WindowSnap class? Since both classes are a bit long I added them to pastebin.com
What i'm doing now is to get all the minimized windows i mean all the the windows in the back if it's chrome browser windows or open tabs if it's program games other windows. This is what i'm doing in form1 constructor:
this.listBoxSnap.Items.AddRange(WindowSnap.GetAllWindows(true, true).ToArray());
int numitems = this.listBoxSnap.Items.Count;
for (int i = listBoxSnap.Items.Count - 1; i >= 0; i--)
string tt = listBoxSnap.Items[i].ToString();
if (tt.Contains(" ,"))
listBoxSnap.Items.RemoveAt(i);
listBoxSnap is just a regular listBox1 in my form1 designer.
And this is the WindowSnap class code, it's a bit long code but it's all connected:
I'm not sure what to show here from this class what is the most important part so i added all the class code to a link to pastebin.com:
WindowSnap.cs
What i'm calling/using in form1 constructor from this WindowSnap.cs class is the GetAllWaindows method:
public static WindowSnapCollection GetAllWindows(bool minimized, bool specialCapturring)
windowSnaps = new WindowSnapCollection();
countMinimizedWindows = minimized;//set minimized flag capture
useSpecialCapturing = specialCapturring;//set specialcapturing flag
EnumWindowsCallbackHandler callback = new EnumWindowsCallbackHandler(EnumWindowsCallback);
EnumWindows(callback, IntPtr.Zero);
return new WindowSnapCollection(windowSnaps.ToArray(), true);
EnumWindowsCallBackHandler is:
private delegate bool EnumWindowsCallbackHandler(IntPtr hWnd, IntPtr lParam);
EnumWindows is:
[DllImport("user32.dll")]
[return: MarshalAs(UnmanagedType.Bool)]
private static extern bool EnumWindows(EnumWindowsCallbackHandler lpEnumFunc, IntPtr lParam);
Then i have the class called WindowSnapCollection:
WindowSnapCollection.cs
The problem is in form1 constructor i'm getting only 23-24 windows in the listBox1. When i'm doing this two lines:
this.listBoxSnap.Items.AddRange(WindowSnap.GetAllWindows(true, true).ToArray());
int numitems = this.listBoxSnap.Items.Count;
I see in numitems about 30 windows and after filtering i'm getting 20 windows and i checked that's the correct number of opened minmizied windows i have in this example 20.
Now what i want to do is somehow to get with all this windows in the listBox also all the opened tabs in chrome.
For exmaple i have only 4 opened chrome windows. But in one of the chrome windows i have almost 40 tabs opened !
I want somehow to add to the listBox all this opened tabs also as captured screenshots like i'm doing now with the windows.
This is a screenshot of my program showing what i'm doing and what i get:
So now i have 19 windows captured in the next refresh it will show 20.
My question is if there is any way to capture also all the chrome opened tabs in all the windows if any opened tabs are opened at all ? Now i'm getting only the chrome opened windows captured screenshot. But i want to get also the chrome tabs captured screenshots.

Hi Chocolade1972,
Since this forum is discussing about Windows Forms general like winform controls, and your issue is related with Windows Desktop SDK, I will move this thread to the more related forum.
Thanks for your understanding.
Best Regards,
