How can i make a text box that changes input constantly?

So I want to create a text box "static if possible" that when my user interacts with the story game the text inside changes to accommodate his action. so im guessing i want a pointer to the char variable, but it seems that i cant figure out how to do this... can someone help me please.

im thinking create the static box with a argument that is a pointer, so i can constantly 开发者_JAVA技巧change its address to another string of text. would this work? because at the moment im changing the value of the char string and nothing is happening.

To change the content of a standard Win32 textbox, you simply send the WM_SETTEXT message.
