MFC 10 - Is it possible to have a CFrameWnd within a CView? - visual-studio-2010

I'm using MFC (yes must be MFC and no I can't interop with .Net) to create a CFrameWnd.
My goal is to create a CFrameWnd containing a CFormView which is based on a Dialog Template that resembles something like:
I have got the frame and view to display, and I have an Edit control on there. Now what I want is to have a CToolbar aligned to the top of the Edit Text control but not docked to the top frame.
Ideally I would like to have a child frame/view that I can dynamically add in place of the Statement Group. That way I could just dock the toolbar as normal.
The thing that I find odd is that I could easily achieve this if I had a splitter in there by using the CreateView function. I really don't want to have a splitter and feel there ought to be another way.
In summary, these are the question I need help with:
Q1 - How can I have a CFrameWnd within a CView (like what CSplitter::CreateView does)?
Q2 - How can I position a toolbar within a CView without docking or floating it within another frame (I'm more than willing to resize, position it manually if only I knew how)?
Now I really appreciate how easy things are in .Net.

I wouldn't recommend sticking a CFrameWnd within a CView. You'll be fighting MFC all the way, basically living in a world of ASSERTs as the internal functionality such as message routing assumes that Frames don't live in views.
Instead just use a CWnd instead of the CFrameWnd and in the 'Create' method manually create the toolbar and the edit ctrl and size and position them yourself (create a AdjustLayout method that uses CMFCToolbar::CalcFixedLayout to adjust the position of your other components).
A great example of this is in the Visual Studio sample app PropertiesViewBar.cpp:

Note: You might need to override OnCmdMsg to extend the message routing to the internal controls.

MFC colored button with native win7 appearance

I am using MFC to create a dialog project and trying to impart color to the buttons.
I came to know that the only way you can do is to make the button owner draw. OnCtlColor() does not work for buttons.
I am able to color the button overriding OnDrawItem , but the problem is that , in the process the 3D cool look (with slightly rounded corner that you get in Win7) is lost.
Is there any way to retain the native look and color the button on top of that?
This is not a trivial task. As long as you are using themed controls (what you want), you cannot do more than the theme allows.
You would have to re-implement drawing of the button on your own, making use of the theme API as much as possible to retain themed look, yet sneak-in your color.
Though note that you can hardly achieve anything better than, what .NET WinForms do, when you set the Button.BackColor:
See also question how to set Button BackColor?
Disassembling the WinForms ButtonStandardAdapter.PaintWorker will give you some idea and API you need to use. Beware, you need to do lots of coding!
For C++/MFC code check out Vista themed Owner-Drawn and Full-Custom Push/Menu/Image Buttons on CodeProject. Which probably actually does, what you want already (the SetBackgroundColor method), so you might reuse it.

How to implement a threaded view?

I need to implement a threaded view of sorts in an old VB6 app. It should look similar to this:
So, it's like a TreeView of sorts but there are buttons on the right (for each row) that could be pressed. The view does not need to collapse - it always stays in the expanded mode. The users should be able to respond to each node (via the comment button on the far right). And, of course, users should be able to scroll through the entries.
What are some of the ways I could implement this? I am open to 3rd party controls, paid or not.
VSFlexGrid has an outline mode. You can set the indent per row via the RowOutlineLevel property. It supports word wrap, images, etc within its cells/columns so you should be able to get pretty close to what you want. It also supports owner-drawn which lets you fully customize the cell painting (for example, to get those rounded corners).
I'm sure there are other controls out there as well...

How to place a windowless control on top of a windows control?

Say, I have an Image control (which seems to be a window-less control) and I want to make sure that it is on top of a TextBox. No matter what I do, the Image control will not appear on top of the Text box.
Is there a way?
P.S. I know I can use a PictureBox, but it does not support transparency, thus I must have the Image control.
There is no way to place an image control over a normal textbox as they are drawn onto the form itself so will always be below any other windowed components.
If you have VB6 installation media there are drawn (windowless) versions of controls including a TextBox you can use that will (probably) do what you want; http://support.microsoft.com/kb/184687
A custom usercontrol of some kind if probably better .. what is it exactly you want to overlay the textbox with?
The Image Control is considered a graphical control, like shapes, so it is always inferior to text controls. If you really want a transparent image, you can use a Microsoft 2.0 Form instead(only if you have it). Images there can be on top of textboxes, and you can make it transparent by setting the Backstyle to Transparent(0).
Completely different approach to my other answer (hence the seperate Answer), but you can set AutRedraw and ClipControls on your Form to false and it will allow the Image control to render on the same layer as a windowed control. You can get some flakey redrawing in some cases but for a quick solution you could try it.

I've created a tranparent overlay control to add a kind of annotation layer on top of a VB6 app. I'll attempt to describe it from memory, and if that doesn't provide enough information then you can post back and I'll try to dig up the code.
First, add a new USerControl to you application. Give it a name like ImageEx, PictureEx, or TransparntImage. There are several properties that you will need to use. Ensure the control is Windowed, so it can sit on top of other windowed controls. Locate the MaskColor property and set it to Cyan (or whatever color you elect to use to indicate a tranparent area. There might be an addition property enable the masking behavior, just browse the properties. Set the control background color to that of the MaskColor. At this point you have an invisible control. In my control I painted on top of the surface for annotations, but you can PaintPicture or maybe even set the image property for a really simple approach.
Of course, to make this a re-usable control, you will want to code in your own properties that allow the MaskColor and image, etc to be set so that you can the drop one of these on any form you want.
Some links:
MaskColor Property
MackPicture Property
1) Remove all your textboxes , labels and ... (But memorize their name and location in the form)
2) Go to (project > components) and mark the (Microsoft Forms 2.0 Object Library) then click ok
3) Now you can see new controls under your default controls in your toolbox...
4) Use its textbox and label controls instead of the default controls
5) Right click on your Image Control then click (Bring To Front)

chrome-like status bar in qt

I'm not big on creating GUI's, and generally my philosophy is: I don't create them, or I make them as simple as possible (and convince myself that it's better for usability :)
For my current project, I'm using Qt from Python (PyQt), and I want to start adding some GUI elements without cluttering the interface.
My idea is to create these elements as sort of floating-shaped-widgets that only appear when necessary; pretty much like the status bar (and find bar) in chrome.
Is there any standard api that enables creating this kind of interface?
This is not very complicated. If you want something like the status bar in Chrome you just need to have a QFrame at the bottom of your windows and show or hide it when you need it.
You have 2 options here, add is as part of your window layout so all the items move up when it is shown. Or you can have if floating, so it will be shown on top of the items. For the second option you need to create the QFrame with the window as parent and then in the window resizeEvent set the geometry of the frame.
This is an example of the second approach:
void MyWindow::resizeEvent(QResizeEvent* event)
{
frame.setGeometry(0, this->height() - frame.sizeHint().height(), this->width(), frame.sizeHint().height());
}
I hope this helps.

Visual C# Express 2008 Form Designer AutoScroll

This may not be the kind of question one should ask on StackOverflow, but here's a frustration that I've been trying to find a work-around for.
When using the form designer, suppose the entire form does not fit in the space allotted to the form designer, and I have a control say, down near the bottom of the form.
If I try to re-size that control, or move it using the mouse, the work area will auto-scroll to the top of the work area. This essentially pulls my control to the top of the screen. It isn't possible to scroll with the scroll wheel while "holding" a control, and even ScrollLock does nothing for me.
Is there any way to just turn the auto-scrolling off? That way I can at least work on my form without guessing numbers to type into the properties window.
Can't you just turn off autoscroll for the form?
I think it's off by default.
Form.AutoScroll = False
