C Sharp :: Change Background In All Forms With Button Click
Jul 14, 2013
I made 2 forms and Form2 has buttons with images like planets and game wallpapers etc. When I write the code for button:
this.BackgroundImage = new Bitmap(Properties.Resources._8_8008_by_amplifier404);
this.BackgroundImageLayout = ImageLayout.Stretch;
// where _8_8008_by_amplifier404 is name of the image located in resources
It only changes background in form which has those buttons as long the form is used. Once I go back to form1 it's changed to null. How to set background in all forms with a button click which will be there until another button with an image is clicked.

For now the app creates a new DateTime property which is binded to a label and shows the user the current time. Eventually I want to have the ability to select the timezone you are in, change font/background colors/etc etc... But that is all in time. My current step that I am trying to implement is having a button click (Binded to an event method) change screens. I find it hard to explain in words, but I would like the same Window to be used, just have different functions on the other when the button is clicked. So for example...
The only way I have found to do this so far is to create a whole new form or create tabs. While those are all good and have their place. I know that I need to start breaking up my code into classes, I am developing a bad habit throwing everything into the MainWindow Class...
Here is the code if needed:
XAML:
<Window x:Class="ClockApp.MainWindow"
xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
x:Name="MyWindow"
Title="Alarm Clock App" Height="180" Width="360" Visibility="Visible" ResizeMode="NoResize" WindowStyle="ToolWindow">
[Code] ....

I've created a new dialog in my MFC dialog based application. the new dialog contains 5 control buttons. The following happens and I don't understand why?
1. click on buttonX. (result ok, OnBnClicked message is sent)
2. click on on any place of the application, but not on the dialog.(removing focus from dialog)
3. click again on buttonX (FAILED, OnBnClicked message is NOT sent). but if instead I click on any other button in the dialog (result ok, OnBnClicked message is sent).
And when I do:
1. ...
2. ...
3. click on the dialog area just to set focus on the dialog again
4. click again on buttonX. (result ok, OnBnClicked message is sent)
**I need to do step 3 only if I want to click again on the buttonX! why?? I think it related to SetFocus() but I m not sure how.
I've tried different style like, tool windows, overlapped, popup. it happens in all the cases.
Code:
class CToolsDlg : public CBDialog {
DECLARE_DYNAMIC(CToolsDlg)
public:
CToolsDlg(CWnd* pParent = NULL); // standard constructor
virtual ~CToolsDlg();
CToolTipCtrl m_ToolsTips;
[Code] .....

Okay, I have a form and I have a tab control thing. On the second tab, I have a button which is supposed to turn the background green.
So, I have this:
#pragma endregion
private: System::Void greenButton_Click(System::Object^ sender, System::EventArgs^ e) {
this ->BackColor = System::Drawing::Color::Green;
But clearly that just turns the FORMS background green. How can I change the TAB background to green.

I'm creating a simple game with my friend that runs in the Terminal/Command Prompt window, but I would like to know how to change the color of the entire window via C++. I'm on a Mac, but my friend is on a Windows, so I need to a solution that is portable, if possible.
I've tried using a printf statement to change the color, but it only changes the background color of the text being printed.

Here is what I did,
Code:
oldHook = ::SetWindowsHookEx(WH_CALLWNDPROCRET, CallWndRetProc, NULL, ::GetCurrentThreadId());
MessageBox(...);
UnhookWindowsHookEx(oldHook);
Then within the callback function CallWndRetProc, I tried to change the background color of the dialog,
Code:
PAINTSTRUCT ps;
HDC hdc = BeginPaint(msg->hwnd, &ps);
::SetBkColor(hdc, RGB(255, 0, 0));
EndPaint(msg->hwnd, &ps);
But it doesn't change the background color of the dialog. I wonder what is the right way to do that?

What I'm doing is giving the user the choice to show 2 different dates. 1 in yyyy-mm-dd notation and the other in dd-mm-yyyy notation.
I'm using a second form to do this.
So from Form1 I have my data in the datagrid and in Form2 I have 2 radio buttons giving the user the choice between Date1 and Date2. So how would I be able to interact with the first form with the radio buttons?

The question says:
Place an Image on top of a Button. Move both when the Button is pushed.
Please have a look at this code:
#include <GUI.h>
using namespace Graph_lib;
//------------------------------------------------
class rotation : public Window {
public:
rotation(Point xy, int w, int h, const string& title):
Window(xy,w,h,title),
[Code] ....
The problem is that, it is not possible to define an Image in public/private part of the class rotation. Image needs all arguments to be supplied even when declaring one. (Image is here in Graph.h)
And if I define that Image in the body of main() function, so how to provide access for void rotate() to change its position with the position of button simultaneously.

I am writing a GUI application with C++ Visual component Libraries and Win32API under windows OS.
As part of this app, I have to change color of the MS Windows button control depending on the external state.
I understood, Win32 will not support changing button control color directly as it will not support for this.
how to change the button color?
