Bring custom control to front

I recently started to learn C# and right now I want to mess arouwnd with the Form[Design].
Right now I'm trying to BringToFront() custom controls each time I hover over a button (Ive got a few buttons close to each other, each time I hover over them I get a certain User Control).
This is what I've got so far:
private void button1_Hover(object sender, EventArgs e)
{
costumControl1.BringToFront();
}
private void button1_Leave(object sender, EventArgs e)
{
CostumControl0.BringToFront();
}
private void button2_Hover(object sender, EventArgs e)
{
costumControl2.BringToFront();
}
private void button2_Leave(object sender, EventArgs e)
{
CostumControl0.BringToFront();
}
private void button3_Hover(object sender, EventArgs e)
{
costumControl3.BringToFront();
}
private void button3_Leave(object sender, EventArgs e)
{
CostumControl0.BringToFront();
}
But bringing to front the user control costumControl0 when I hover from a button to another it's not what I want.
But I don't know how to go about this.
Is it possible to just add a if statement where I check if I'm not hovering the buttons close to my current one and then display the costumControl0.
Or a timer is necessary to delay the display of the costumControl0 and skip the command if I'm starting another event.
If the timer is needed, can I use one timer for all of the buttons or do I need to create one for each?
Or whats the best approach for this?

C# How to set button text of different buttons to the same textbox

I have a couple of buttons and a textbox. I want to make it so that when I press button1 the text from the textbox goes to button and when I press button2 the text goes to button2 and so on. I now have this:
protected void Button1_Click(object sender, EventArgs e)
{
Button1.Text = TextBox1.Text;
}
protected void Button2_Click(object sender, EventArgs e)
{
Button2.Text = TextBox1.Text;
}
protected void Button3_Click(object sender, EventArgs e)
{
Button3.Text = TextBox1.Text;
}
Edit: Is there a shorter way to do this?

If you point the Click event for each button to the same method you can have this in one method like so;
protected void Button_Click(object sender, EventArgs e)
{
((Button)sender).Text = TextBox1.Text;
}
You can change the method that is used for a button event in the designer by clicking on the button, going to the Properties window and clicking on the little lightening symbol for events and selecting the Button_Click method for the Click event.

How to make textbox appear only after user clicks button in c#

How would I make a textbox appear only after clicking a button. THis means that It should be hidden, and once user clicks, then it can appear.
private void button7_Click(object sender, EventArgs e)
{
// .. what next?
}

You can use Control.Visible to make any control visible or hidden:
private void button7_Click(object sender, EventArgs e)
{
theTextBox.Visible = true;
}
Just set it's Visible property to false initially (ie: in the designer).

Assuming you have defined a TextBox textBox1 somewhere:
private void button7_Click(object sender, EventArgs e)
{
textBox1.Visible = !textBox1.Visible;
}
This way you can toggle the visibility.
You can set it just to true if you like, but make sure the initial Visible state, you can set it in the designer, is false.

in c#, how can you disable a button after the 1st click, and enable it again after you click another button?

I cannot figure this out
i'm making a windows form application with visual basic in c#
i have a scan button and it scans everything in the folder and lists all of the files in the listbox
if you click it another time the list of files appear again
how can you make it so you can only press the scan button once, and then you can press it again if you click the browse button?
the browse button is to select the folder you want to scan
thanks

This is pretty trivial
private void ScanButtonClick(object sender, EventArgs e)
{
// do something
(sender as Button).Enabled = false;
}
private void BrowseButtonClick(object sender, EventArgs e)
{
ScanButton.Enabled = true;
}

Its a bit unclear if you're writing in C# or vb.net, but since the question is tagged as C#...
private void btnScan_Click(object sender, EventArgs e) {
btnScan.Enabled = false;
// other code here
}
private void btnBrowse_Click(object sender, EventArgs e) {
btnScan.Enabled = true;
//other code here
}

I tried this in my windows form application in C# and it works fine!
private void button3_Click_1(object sender, EventArgs e)
{
int count = 0;
count++;
//add your code here
if (count == 1) {
button3.Enabled = false;
//only one click allowed
}
}

Show/Hide button on MouseOver

I have a button on my WinForms app that I want to be invisible until the user moves his mouse over the button. Then they could click it. If the mouse leaves the button, it needs to be hidden again. The button.Visible parameter makes the button completely inaccessible and disables the mouse over. Any ideas or other button parameters I could use?
This currently does not work:
private void settingButton_MouseEnter(object sender, EventArgs e)
{
settingButton.Visible = true;
}
private void settingButton_MouseLeave(object sender, EventArgs e)
{
settingButton.Visible = false;
}

This issue was brought up and answered here:
C# WinForms MouseHover and MouseLeave problem
private void Form_MouseMove(object sender, MouseEventArgs e) {
if(settingButton.Bounds.Contains(e.Location) && !settingButton.Visible) {
settingButton.Show();
}
}
