SetDlgItemText

SetDlgItemText is a function in the Windows API used to set the text of a control in a dialog box. It is part of the User32 library and is commonly used in Windows applications to update the content displayed by controls such as labels, buttons, and edit boxes. The function takes three parameters: the handle to the dialog box, the identifier of the control, and a pointer to the new text string. The function returns a nonzero value if successful, or zero if it fails. This function is particularly useful for dynamically updating the user interface based on user actions or application state changes. It is often used in conjunction with other dialog box functions to create interactive and responsive applications.
