Simple Edit Box problem, help!

[Desvario]

I guess it is simple...

I have this edit box where i am trying to show a HUGE amount of text. The problem comes when you scroll the same edit box, the lines that is beeing scroolled become "overwrited".
How to avoid this? By Invalidate everytime someone scroll the editbox?

Please help.
Thanks.

Nope, I think this might be issue with Edit control.

What is text size in bytes ?

[Desvario]

Hi there...
Thanks for the reply...
The actual size of the text i dont have idea, but is an entire A4 page full of text. And the edit box area is just half of the A4 size, so in order to check the rest of the text, you have to scroll. And the problem comes when u actually scroll. The text gets overwrited.

Any idea, hints, suggestion?
;-)

Thanks.

Thats weird, it's not that huge data, and I tried it here and dosent happen as you have described. Are you doing any event processing on that edit box ?

[Desvario]

What i did is that to the editbox, i attached a variable CString m_text.
to this m_text i just did: m_text = " the hole text...."; where the hole text is the equivalente of a A4 page.
But when i scroll, it gets messed.

Can i send u the code?

Thanks.
Desva.

Yeah, post it here.

Also can you try (make a copy of project) removing the CString member variable and use

SetWindowText(hWnd_Edit , szText);

[Desvario]

Ok...
I have a dialog, on this dialog there is a EditBox to which a variable type CString is attached called m_text.
This m_text has a A4 long text. The EditBox is just half of a A4 therefore to read everything you need to scroll the area, but when doing this, the text gets overwrited.

I tried your last suggestion, check what happend:

	error C2660: 'SetWindowTextA' : function does not take 2 parameters

I did

SetWindowText(IDC_terms , m_tt);

where IDC_terms is the name of the EditBox and m_tt is the name of the variable that is holding the entire A4 of text.

Thanks... but continue the same
:-D

First parameter of ::SetWindowText() is the handle to the window( in your case it should be the handle to the Edit box) but you pass the Edit box ID which is different thing.

Anyway try this:

HWND hEdit = GetDlgItem(IDC_terms );
::SetWindowText(hEdit,"some text");

OR

SetDlgItemText(IDC_terms,"Some text");

Cheers

you might wnat to consider using the MS TextBox control. you would have to add that to your project (activex controls).

Hi there!
Thanks for the reply...
I found the problem, but still not knowing how to solve it...
I am using a SKIN, so everytime the editbox is scrolled the skin seems NOT to be redraw...
I will upload the project so if anyone wants to give me a hand.

In order to check the error, u must "de-select" de text on the edit box and just then scroll it. And this is something "interesting" since if the text in the edit box is selected and then u scroll, nothing happens, but if it is the way around, the error appears.

Anyone knows why?

Thanks again.

It's Better if you Simple go for a CRichEditCtrl instead of edit control.

[Desvario]

Hi there...
Again, thanks for the reply.
I just checked that option and there is a little "big" problem.
I must give the address to load the file, right?
I cant, since it must be "hardwired" or the text, no matter if it is huge, must be in the code itself.
Have you checked the attached file?
Thanks...
cheers!
