OK, so I have a Windows Forms Application in C++. It has 3 forms. In Form2.h i have 3 textboxes . I want you to give me the command (and where to put it) , so that when I enter values in the 1st and 2nd texbox, they are summed in the 3rd textbox
Here is my code for the Form2.h ... please edit it and place a right command on the right place, so my idea will work . (P.S. I've read a question simmilar like this here, but it didn't help me).
Code:
