Hi
Actually i have Rich text contol present in my dialog. I will get messages from the board, when the messages exceeds the size of the window, scroll bar automatically comes because of i had set the scroll bar(Vertical scroll bar) property of Rich Text Control.
My question is, when message exceeds the window size, the scroll bar automatically goes up. i don want scroll bar to move up rather it should go down, then only i can able to see latest updates form the board at time itself.
Thanks in advance,
Thanks,
Balaji

Not sure that I understand. When you say "get messages from the board" do you mean the keyboard? I also don't understand how adding text to a rich edit control moves the scroll bar up. If you add text to the end of the edit control then the scroll bar moves down for me. The text does move up.
Perhaps you can try LineScroll() with a negative number of lines. For instance
MyEdit.LineScroll(MyEdit.GetFirstVisibleLine(), 0)
makes the top line of the text in the edit control visible

Hi Graham,
thanks for ur reply. I'm explaining the problem on behalf of Balaji.
Problem :
Information in Rich Text Box are updated by thread, whenever thread gets message(text), it will be updated on RichTextBox Control.
Right now, we are concatenaing the message(text) and update the concate_string in the RichTextControl, using the following API,
myRichTextBox.SetText(concat_string);
What we are suppose to do is, recently updated text should be visible to user.
To view the recent text, we are using scroll bars manually. Instead, we want to display the last updated text.
we are using Rich Text Box 6.0 (SP4). we tried with the following APIs,
myEdit.SetScrollBar();
but it's throwing Error..
Thanks

OK, things are a lot clearer now, thanks. I was assuming that you were using the CRichEditCtrl from MFC, but you are actually using RichTextBox from the .Net framework library
What I think you want to do is:
a) Before appending the message to the RichTextBox get the current length of the text from the TextLength property. This is the char index of the last character of the last message
b) Calculate the line number of this position using GetLineFromCharIndex
c) Append the text
d) Calculate the line number that you want at the bottom of the display from the number calculated in b) plus the number of lines in the display
e) Calculate the char index of the beginning of the line calculated in d) using the GetFirstCharIndexFromLine
f) Set the caret to begining of the line calculated above using the Select method
g) Scroll the caret to the bottom of the display using the ScrollToCaret() method
The following code should do it (note I have not tested this yet)
int line = myRichTextBox.GetLineFromCharIndex(myRichTextBox.TextLength);
myRichTextBox.SetText(concat_string);
int pos = myRichTextBox.GetFirstCharIndexFromLine(line + NumberOfLinesInRichTextBox(myRichTextBox));
myRichTextBox.Select(pos, pos);
myRichTextBox.ScrollToCaret();
As in a previous answer[^] the function NumberOfLinesInRichTextBox could either return a constant value determined by experiment or calculate the number of visible lines in the RichTextBox using Text Metrics.
Apologies for not having time at the moment to test this out, but I hope I've given you enough of a steer to allow you to get this working

Hi all
I would like to stop executing the
std::getline( std::cin, aString )
function from another thread
when getline is blocked waiting for user input.
A possible solution is to put the function into another thread
and stop this last when I need.
Instead of using another thread, is there some global
function or OS function that is possible to call?
I imagine since std::cin should be running in a OS
thread, right?...maybe some signal?
Thanks for your help

Please let me how to change the font of parent node and also how to make it BOLD in tree control.
Thanks in Advance
|
|

There is no TVM_SETITEMFONT message, and TVITEM has no font member - so you're going to have to roll your sleeves and do it yourself.
Or, there are plenty of articles on codeproject to do with owner draw tree controls.
It's a shame, though - I'd think font is quite a good extension to a tree view item properties. But it's not up to me!
Good luck,
Iain.

You can change the font with custom draw. Handle NM_CUSTOMDRAW and select a new font into the DC that you get with the message. Bolding an item is built-in, set the TVIS_BOLD style on the node (or you can just select a bold font when you handle NM_CUSTOMDRAW).

I am trying to build this custom control - one of the child windows is an edit control and at one point it gets the focus (you can type in it) but the cursor has disappeared... what could cause this and how can I fix this?
Thanks in advance

That's the default behaviour of the edit field, you can see the same behaviour in a lot of programs, when you start typing, it hides the mouse cursor. Just run notepad and start typing...
