Re: Updating Scrollbar in editbox .... - C / C++ / MFC Discussion Boards

Hi I think if you are using MFC you can simpy use the function LineScroll with a number greater that the required and you will automatically scroll to the last line. But if you are not using MFC, you can try the following mesg ::SendMessage(m_hWnd, EM_LINESCROLL, nChars, nLines); use the nChars as zero and the nLines as a great number as possible Kumar

Here is one method to append text and updating the scrollbar. Suppose you have a CEdit named m_wndText:

int nSel = m_wndText.GetWindowTextLength(); // Get length of text in the textbox
m_wndText.SetSel(nSel, nSel, TRUE);         // Put cursor at the end, without scrolling
m_wndText.ReplaceSel("Add this text");      // Add some text...
nSel = m_wndText.GetWindowTextLength();     // Get new text length
m_wndText.SetSel(nSel, nSel);               // Scroll to the last char

This is usually faster than getting the text with GetWindowText(), appending a string and then updating the entire textbox with SetWindowText().

Hi,
I have to create a application that works almost like a SlideShow that is available in WindowsMe ( in Pictures Folder ), except that I have to kept the pictures in exe so no one can copy it in addition I also want to disable the ( PrintScreen ) & ( Alt+Print Screen ) to disable capturing of the pictures.
So the target picture in full screen with a Next, Previous, First & Last & Exit buttons in a corner of a screen. I can put the Images in the Resource tab & then call them using the Image Control. Am I going the right way.
Any help according to this is appreciated.

Hi try to look into Global Hooks, which can trap windows keyinput. Like for ex you might have seen CBT and CB-Training programs, which do not seen to repond to the standard windows keyinput also. You can get a Global Hook and trap the keyinput and not forward the mesgs. kumar

And what about the app, which stays in memory, and every 5 secs gets active window and make copy of its dc to bmp and to file on disk? No user interaction - but works. I think that there is no way to totally block such possibility.
Do not put images (in bmp/gif/iff/jpeg/... format into the resource, cause many application (for example MsDev) can easily read resources from executable. Open exe as resource, and then export what just You want.
To workaround above problem, You must compress/encrypt or in other way alter images. Do not use commonly known algos, like zip and rar.
Hope this helps Smile | :)

I am currently experiencing problems with the rich edit control and
RTF text in piece of software I've written.

I have a Rich Edit View, using version 1 of the Rich Edit Control, for
display various pieces of RTF text. The text is edited via a dialog.

Running under Windows 95, Windows 98, Windows Me and Windows NT 4.0 I
have experienced no problems. However under Windows 2000 the RTF text
becomes corrupt when displayed. The text in the edit dialog is OK. It
seems that the font definitions in the display are being switched
round in 2000. For example,
in everything else f0 may be Arial, f1 roman, f2 symbol. But under
2000, it switches the number used for symbol, so I end up with
something like this - f0 Arial, f1 symbol, f2 roman. This causes the
text to be displayed wrong.

As far as I can see I have 4 options:

1. Use a newer version of the Rich Edit Control, but this might have
unwanted side effects on the other platforms.

2. Release a special Windows 2000 version of the software.

3. Write some kind of parser that will reset all the fonts every time.

4. Abandon RTF and use an HTML view control, but this would require
major rewrites.

Any help would be appreciated.

Thanks,

Andrew Sage
