    Edit/Rich Edit window size restrictions

    When creating an edit/rich edit window is there anyway to overcome the size restrictions? Rich edit windows only hold 32k, while edit windows can hold up to 65,535 bytes.

    After visiting Microsoft's website I learned that Wordpad uses MFC's doc/view architecture to display/edit plain text, etc. Can the same results be achieved without using MFC? (I mean using C since I don't have visual C++).

    Thanks

    You can upgrade your Windows version to get more space from an edit control or stream text to a Rich-edit. Look up the EDITSTREAM struct.

    Thanks Sorensen, you set me in the right direction.

    I searched for EM_STREAMOUT and found a site that also explained the default text limit in a rich control is 32k, but can be set higher with the EM_EXLIMITTEXT message.

    I tried the value 0x7ffffffd and it set the limit to 173,536 bytes -- haven't tested higher values yet...

    thanks again
