WIN32 PROGRAMMING, HOW TO ADD CONTROLS

3.Right-click on the folder, add resources, and then select Dialogs to add a dialog. Then the dialog box and toolbar will automatically appear, you can click on the toolbar on the right to click on the desired control (such as a button), then click on the middle dialog box to hold on, and then drag the mouse to "draw" the control on the dialog box.

If you need to add a new dialog, you can right-click on the resource folder to add it.

Click on the space on the right, and then draw a rectangle on the box on the left.

How good its practical MFC is, many things are written directly for you by the system.

Win32, you need to live your own button class object, and then call the create function to dynamically create a button, set the resource ID and coordinate location, and then write a message response.

Let's see if there's an API like drawimage

WM hasn't done it.

How do you write that?

Post it out and take a look.

This stuff is probably going to be used by you.

The VS2010 I am using now is to open the dialog box where you want to add a button in the resource view, and then right-click on the button, select "Add Message Response Function", and then it will let you choose which class to put the function in, and then automatically generate the declaration, message and definition of the function, and then you can write the operation you want directly in the function definition.

Under MFC programming, just double-click the button you want to add.

1. Open the dialog box to add a button in the resource view, then right-click on the button, select "Add Message Response Function", and then select which class to put the function in, make sure to automatically generate the declaration, message and definition of the function, and then write the required operation directly in the function definition.

2. In the oncommand method (if you don't add it yourself), take out the high and low bits of wparam, the low bit is the control ID, and the high bit is the message uint message=hiword(wparam);

int nid=loword(wparam);

Then determine whether this ID is the ID of the control to be responded to, and determine whether the message is a message that needs to be responded to.
