Can you elaborate more on the error and on which line you are getting it? It is not clear from your description.

original:
private void Button2_Click(object sender, EventArgs e)
{
SHEmptyRecycleBin(IntPtr.Zero, null, RecycleFlag.SHERB_NOSOUND | RecycleFlag.SHERB_NOCONFIRMATION);
}

above is my function, when i click the button, it will clean my dustbin. The code that i actually trying to do is, i need to tick the checkbox and click the button and then the dustbin wil clean up.

latest code:

private void Button2_Click(object sender, EventArgs e)
{

checkBox1.Checked = SHEmptyRecycleBin(IntPtr.Zero, null, RecycleFlag.SHERB_NOSOUND | RecycleFlag.SHERB_NOCONFIRMATION);

}

Question: how actually can i combine checkbox and button, to execute this program ?

Sorry mate for my unclear question.

Solution 1

SHEmptyRecycleBin return integer (int) value

if successfully empty Recycle Bin then return 0
and if Recycle Bin already empty and you fire button click then return value like -2147418113

so, you need to change code accordingly true false for check box checked/unchecked
