MFC dynamically creates a button and implements a toggle display of the bitmap on the button "

Create a button dynamically and add a bitmap to the button to display a different bitmap by clicking the button, which can be set to show the button pressed and bounced in two states. Just determine the a value and enter a different response code.

1, add in the header file:

CButton *pbtn;

2. Add in the initialization function:

PBTN = new CButton ();

Pbtn->create (_t ("My button"), ws_child| Ws_visible|bs_pushbutton|bs_bitmap, CRect (0,0,100,40), this, Idc_button);//button display Name, property, ID number

Pbtn->movewindow (CRect (400,100,500,140));//position and button size

Pbtn->setbitmap (HBITMAP) LoadImage (AfxGetInstanceHandle (), "1.bmp", Image_bitmap, 0, 0, lr_loadfromfile | lr_createdibsection));//insert Bitmap, the position of the bitmap to be placed in the program

At this point, the program can display the button, and if there is a bitmap, the bitmap will appear on top of the button;

3, in the Resource.h

Add ID Number: such as # define Idc_button 1002

4. Below the header file

Protected

{{afx_msg (Cmy3view)

Note-the ClassWizard would add and remove member functions here.

Do not EDIT these blocks of generated code!

}}afx_msg

afx_msg void Onbutton ();//This Statement of function

Declare_message_map ()

5, in

Begin_message_map (Cmy3view, CFormView)

{{Afx_msg_map (Cmy3view)

Note-the ClassWizard would add and remove mapping macros here.

Do not EDIT these blocks of generated code!

}}afx_msg_map

Standard printing commands

On_bn_clicked (Idc_button, Onbutton)//Outside (ID number, response function number name)

End_message_map ()

6. Add the response function manually

void Cmyview::onbutton ()

{

MessageBox ("response function added test succeeded");

}

7. Add an integer member variable to the header file

int A;

8. Initialization in constructors

A = 0;

9. Add in the button response function

void Cmyview::onbutton ()

{

if (a%2 = = 0)

{

Pbtn->setbitmap (HBITMAP) LoadImage (AfxGetInstanceHandle (), "2.bmp", Image_bitmap, 0, 0, lr_loadfromfile | lr_createdibsection));

}

else if (a%2 = = 1)

{

Pbtn->setbitmap (HBITMAP) LoadImage (AfxGetInstanceHandle (), "1.bmp", Image_bitmap, 0, 0, lr_loadfromfile | lr_createdibsection));

}

a++;

}

It is recommended to use the CBitmapButton class if you simply implement a bitmap switch for the button.
