outside your dialog it isnt your message => no way

except your others windows are informing your dialog via messaging.

When your modal dialog is active, the other windows in your application are deactivated, so can't receive input like mouse button presses.

However - you do get WM_SETCURSOR messages[^] when mouse buttons are pressed outside the window, with the hi-word of the lParam set to the mouse-message that has caused the WM_SETCURSOR message.

Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Getting unicode string

How get unicode string( say Arabic ) from a RichEdit control and to draw that string in a DC using DrawText? Also I want to know how to store unicode string for later use?

Getting Unicode out of a rich-edit control:

Use EM_STREAMOUT[^] with the flags set to SF_TEXT|SF_UNICODE
Use SendMessageW (i.e. the Unicode variant of SendMessage) to send WM_GETTEXT to the control (IF there is less than 64K characters in the rich-edit control)

BenjaminBruno wrote:

Just make sure you use the Unicode variant of DrawText and that the font you're drawing the text with has glyphs for the characters you want to display.

BenjaminBruno wrote:

How much later? If it's just within the same run of the program, then a variable of type CStringW[^] would do the job nicely. To save Unicode to a file on-disk, the routines in this article[^] look useful?

Dear All,

I am working on VC++ and developing a tool for Weather monitoring system.
Here I am facing problem in displaying different views for same dateset from the document class, where all the calculations are take place.

Here I am using SDI Multiple views architecture.All (Two) views are controlled by the menu and they are switching fine.

At this moment only one view is connected to the document and displaying the date.Second view is not updating the data implicitly.

Please suggest me an idea to update the data to both views concurrently.

Thanks in Adavance
Madhu

use Invalidate() or an user defined PostMessage to inform the view to redraw.

Hi KarstenK,

Thanks for your prompt reply and valuable suggestion.

I did try with Invalidate().

I have wrote code as follows

/ / This is View1 connected to the document with

void CStringView::OnDraw(CDC* pDC)
{
CPoemDoc* pDoc = GetDocument();
pDoc->UpdateAllViews(NULL);
}

//This is View2 to be updated

void CHexView::OnUpdate(CView* pSender, LPARAM lHint, CObject* pHint)
{
// TODO: Add your specialized code here and/or call the base class
Invalidate();
}

But it is not triggering OnDraw() of CHexView().

I do not have any idea about user defined PostMessage to redraw.

Please give me some idea to move on...

Thanks
Madhu K

are you shure that CHexView::OnUpdate() got called.

use RegisterMessage() to get a valid message id and use PostMessage() to send it to your CHexView-Window.
Write a message handler

Read the msdn or google for the bold stuff

where is this function defined? A linker error usually means that the compiler is unable to find the definition of the function. You may need to specify the library for it under the linker settings.

You need to google first, if you have "It's urgent please" mentioned in your question.

Why obviously ? Seing your error and the fact that you are sure that you have a body for your function, then I would say that it is obvious that the file is not added to your project.
I am talking here about the cpp file, not the h file. How did you add this file to your project ?

Can you also post the function prototye (which is in the header file) and the function body (which is in the cpp file) ? Please use the code tag to format the code properly when posting.

Note that if you're building for Unicode then the first is an ANSI string and the second is Unicode and so the second in NOT the definition of the first.
