Did you specify the "Report" style for the control?

I do not see any property like that in the property window. How do I set it?

It's the 'View' property - set the 'View' property to 'Report'.

How do you route message to a view?

I have a CFormView. I want to handle menu events in my View. But my CFrameWnd is actually capturing the events of the Frame level. For example, I want to handle Window-maximize event from my CFormView. Or if there's a way I can route the message from CFrameWnd to CFormView, it'll be great. Any idea?

Only if you have relevant handlers in your frame?

I have a vanilla SDI app. I've just added a handler for ID_FILE_OPEN to the view class. It caught the relevant message.

For the maximize event, you will have to explicitly route the message. Add the following handler to your frame class and your view should get visibility of maximize events.

void CMainFrame::OnSysCommand(UINT nID, LPARAM lParam)
{
   GetActiveView()->SendMessage(WM_SYSCOMMAND, nID, lParam);

   CFrameWndEx::OnSysCommand(nID, lParam);
}

Also Stuart, how do we access the Document from a Dialog that I added through "insert new dialog" in resource option?

Re: From A FrameWindow

Stuart Dootson4-Mar-09 6:22

Well, you would need to tell the dialog about the document. You could add a CDocument* member variable to the dialog and set it before you call DoModal.

Alternatively (and I prefer this one), just pass the relevant attributes of the document to the dialog, so the dialog doesn't need to know about the document - letting the dialog have visibility of the document class upsets my aesthetic sense.

use of MFC library

Hi to all again,

Here is an another doubt of mine.
while creting an mfc application it ask "how would you like to use the mfc library" .And the options are
1. as a shared dll
2. as a static linked library

What does this actually means?What is the difference?Is there any relation between this option the exe size.

Thanks in advance

I am a beginner

It specifies how you will link to the MFC libraries:
- static linking, in which case, all the required MFC functionalities are imported into your application. Which makes the exe size larger.
- dynamic linking (dll), in which case you use a MFC dll which makes your exe size much smaller. The draw back is that you need to distribute the MFC dlls along your application (if they are not present on the target machine).

(probably bad explanation, I'm still not fully awake)

1. Will use the shared MFC dll : meaning that if you have 2 different MFC applications with this setting, they share the MFC code in the DLL; meaning the MFC code is NOT included INSIDE your application, making it size smaller. There are potential issues if there are different versions
of MFC dll installed (or not) on the target machines (refer to DLL hell), most of the time you will need to ship your application with the "redistributable" (sp?) DLLs, makeing the installation packages bigger.

2. static linked : ill include the MFC code INSIDE your application, making it fully independant and stand-alone, and should run on target machines without MFC installed; this will make the application bigger, but will remove most (if not all) external dependancies, and limit DLL hell.

I think someone explained you few hours before.[^]

When you statically link it. (just like you link an MFC runtime) This gets added to your executable. You will not have a dependency but the executable size becomes bigger. When you link dynamically, the dll is kept independent and your exe uses it everytime and hence the advantage. Any number of exes can share the same dll.

please help me to draw a arc betwwen two lines without using windows API.

and then i have to find angle betwwen these lines.

this code is being written for a embedded project in VC 6 thats why i cant use windows APIs.

Your question is a bit vague. Which information do you have for each of the lines ?

And how will you draw something if you can't use the windows API ? With your pen maybe ?
There is still a windows API even if you develop for an embedded platform.

actually i am new in this field thats why i wrote as per my scope and thats why i am here to take help from you guys...

so details for first question-->
i have these three co-ordinates for these two lines.
these arc will be drawn basically to show angle measurement

and in this product there will be some RTOS thats why i wrote not to use windows API..i may be wrong in this context Smile | :)

Which 3 coordinates ? I guess (but it's just a guess) the coordinates of the intersection point, and of the two other end of the lines ? Are the two segments the same lenght ? If yes, that would help a lot because then you know that the center of the circle is the intersection point.

You told us you were using VC6 Confused | :confused:

. So, which platform are you targeting ? To draw something on the screen, you'll probably need to use OS specific functions.

If you have the coordinates of three mainingful points (for instance one of them must be the intersection between the lines Roll eyes | :rolleyes:

) then you may calculate the component of the vectors, take the dot product, divide by the vector modules and finally use the inverse cosine function to get the angle (well one of the two...).

As about drawing without APIs, I have a suggestion: [^].

1. Find the forumla to generate all the points[That makes up the arc] between given two points.
2. SetPixel() all those points.
