How much text can a CEdit control contain?

Hi all,

I have created a dialogbased MFC application. The dialogbox contains a normal editbox based on CEdit. I need to write at least 100kB text out in the editbox, but it will only display about 40kB of the text.

Is this the upper limit for the CEdit control?
Can a RichEditBox contain more text?
Any other suggestions to how a can solve this problem?

Thanks

Hi,

you are right, the capacity of a CEdit control is limited (obviously it's based on 16 bit-code). If you want to display more text in your dialog, you should use a CRichEditCtrl instead.

Greetings, Jörg

the limit is 64k if my memory is correct...
However, you can have an amount of text which is only limited by the amount of memory available on your computer (virtually unlimited) in a RichEdit control

no it doesnt work
is there some setting i must do?

to use a CRichEditCtrl you have to call the AfxInitRichEdit once before using these controls! If you have a Dialog based application I would recommend to make the call in the CWinApp derived class in the InitInstance function.

You can change the amount of text that a CEdit can hold by using SetLimitText.

Hope that helps.
