Issue with Form.Close() in Winforms

I have a custom form called CustomMessageBox In that form, I have a method that defines a button click, when the button is clicked the form will record the action and close. I also have a method for CustomMessageBox_Formclosing(), which is called automatically when the form is closed. Now the issue is, within CustomMessageBox_Formclosing(), i have an implementation to handle if the close reason was user induced i.e. the user clicked the X button. But the kicker is that the button method defined earlier, interpretes the close method as a user induced close. How can i resolve this?

What I have tried : Setting the form's .Visiblle to false, which works in theory, but i dont want to leave many forms open like that

I am not sure I understood your needs but how about this

bool button = false;
private void button1_Click(object sender, EventArgs e)
{
    button = true;
    this.Close();
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing && button)
    {
        // user clicked button
        button = false;
        return;
    }
    e.Cancel = true;
}

bool button = false;
private void button1_Click(object sender, EventArgs e)
{
    button = true;
    this.Close();
}

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
    if (e.CloseReason == CloseReason.UserClosing && button)
    {
        // user clicked button
        button = false;
        return;
    }
    e.Cancel = true;
}

basically when button is clicked u set a flag to true and then it will check both the flag and the reason if they match it closes otherwise it ignores you can also hide the close button

Not really but im open to trying a new approach

leowest•3mo ago

what is your goal? because from what u said u want to know if the click came from the button vs the X

Yes exactly I managed to find a solution, I used a slight modification to what you described. Thank you

yeah I mean the idea is simple just using a bool to identify where it came from since its only 2 locations

Use the /close command to mark a forum thread as answered

can anyone use this when its done, or is this just for admins?

leowest•3mo ago

its only for who created the thread and mods+ but the bot sending the message anyone can do its just $close

oke•3mo ago

so someone pasting a powershell script without code blocks could really fuck the bot over

leowest•3mo ago

try and find out

oke•3mo ago

$close = "$close"
