c# - How to make a manually created button invisible after it is clicked in Windows Form? -


Manually created a button using the code below, usually with the button I have my visible = false to invisible, which I do in the setInvisible method when I click the button. I can not do this manually with the built-in button, though? 

  myButtonObject start = new myButtonObject (); Public mainstream () {Initial group (); EventHandler My Handler = New Event Handler (Startcall); start.Click + = myHandler; Start.Location = new system.downing.point (200, 500); Start.Size = New System Drawing. Size (101, 101); //start.Text="Start "; This.Controls.Add (start); } Zero start_Click (object sender, System.EventArgs e) {start.Visible = false; SetInvisible (); // sets a set of invisible set buttons; // Set sets another group} Public class myButtonObject: UserControl {// New button Draw. Secure Override Zero OnPaint (PaintEventArgs E) {Graphics Graphics = E. Graphics; Pen myPen = new pen (color black); // Draw the button as a circle graphic. FillEllipse (Brush Goldnode, 0, 0, 100, 100); Graphics Drylips (MyPain, 0, 0, 100, 100); Text renderer Dave Text (Graphics, "Start", New Font ("Ariel Black", 12.25F, System. Drawing. FONT City. BOLD), New Point (23,37), SystemCollars.Control Text); myPen.Dispose (); }    
 
 
 You can create your manually created button  field ,  outside the constructor :  
  start mybuttonObject private;   
 Something like that  
  public class mainframe () // // in any property // button declaration as a field to access it Do class private myButtonObject start / method / creator; ...} Public MainForm () {InitializeComponent (); Start = new myButtonObject (); EventHandler My Handler = New Event Handler (Startcall); Start.Click + = myHandler; Start.Location = new system.downing.point (200, 500); Start.Size = New System Drawing. Size (101, 101); This.Controls.Add (start); ...} private void setInvisible () {... // You can use the button within the setInvisible () method. View = false; }

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise. To clarify - this will not be a method error because it is a linked list. There should not be any way involved. import java.awt. *; Import java.awt.event. *; Import javax.swing. *; Import java.util. *; Import java.util.Scanner; Import java.util.LinkedList; Public class TopTenList JFrame {Private TopTenList tt; See the Private JTextArea list; Private JTextField cmdTextField; Private JTextField resultsTestfield; // This GUI window is the code for the public toptist...

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
