I am having a problem loading a file into an editing dialog box, if the file is too large to load into notepad it won't load into my program. is there a different type of window or dialog box that can hold more text of larger files? I will need to have enough room to load a file with 65,532 bytes and more.
thanks in advance for any help or point in the right direction.
