Well, what's actually stopping you?

I can see a few steps:

First, you need this to toggle on and off. If it was on all the time, anyone using this dialog will hate you. "I just tried to press OK, but the damn button keeps moving!"

You'll need to subclass your button(s), and override WM_LBUTTONDOWN,WM_MOUSEMOVE,WM_LBUTTONUP. For the button messages, either pass them on as normal, or toggle a "I'm dragging flag". In the mouse button, subtract the current position from the last position, and move the window by that much. Something like:

void CMyMovableButton::OnMouseMove (UINT fFlags, CPoint ptMouse)
{
    // Translate point into parent coords
    if (m_bDragging) // toggles in OnLButtonDown/Up
    {
        CWnd *pParent = GetParent ();
        // Translate coords to parent coords.
        MapWindowPoints (pParent, &ptMouse, 1);
        CPoint ptDelta = ptMouse - m_ptMouseLast; // you did save the lbutton down position, I hope!
        MoveWindow (ptDelta.x, ptDelta.y);
        SetWindowPos (NULL, ptDelta.x, ptDelta.y, 0,0, SWP_NOSIZE | SWP_NOZORDER);
        m_ptMouseLast = ptMouse;
    }
    else
        __super::OnMouseMove (fFlags, ptMouse);
}

You'll also need to store all your window positions when the dialog closes (or store them whenever a control has finished moving) so that you can use that information next time the dialog is used. Maybe make structure full of CPOints (ie, ptOKButton, ptCancelButton) and save that in the registry for use in you CMyMovableDlg::OnInitDialog function?

You might also want to look at CDiagramEditor - DIY vector and dialog editor[^] for an alternate way of doing all this.

It sounds like you have a lot of work ahead of you - and I know no shortcut. I hope you have a strong business case for this, and not just "wouldn't it be cool?"

Maybe when you're done, you could write an article based on it?

Good luck,

Iain.

Have a look at ListView_SetColumnOrderArray. It should do what you're looking for.

remove space for title at top of groupbox?

permutations13-Apr-10 12:04

Is there any way to remove the space for the title at the top of a groupbox. When I use the GetWindowRect property, it's giving me a rectangle with a gap at the top. I don't want the gap - I want the dimensions of the entire group box, with title area (which I am not using). How do I get this? I found a solution for .NET here, but nothing for MFC:

I'm obviously misunderstanding, but what is the difference between the "gap at the top" and the "title area?"

No difference - I'm talking about the title area. Is there a way to style the groupbox so no space is given to the title and GetWindowRect will return the entire groupbox, all the way to the top?

Not that I know of. You might try taking the height of the font and dividing it in half, since that's how much sticks above the group border.

Is there any built-in interface to allow me to make an extension for explorer that sits in explorer's title bar? If not, what is the best way to hook explorer so I can put something in the titlebar?

Visual Studio 6.0 to Visual Studio 2008 Issue

djcouture13-Apr-10 9:23

Hi,

I upgraded a legacy C++ application from Visual Studio 6.0 to Visual Studio 2008. The application mimics the front panel of a fire alarm system and is implemented by overlaying a bitmap drawing of the fire alarm panel with hidden button controls. When the VS 6.0 version was run with a resolution different than what was originally used to create it, the bitmap and the button controls became misaligned. After upgrading to Visual Studio 2008, this misalignment problem went away(!), so that I could run at any resolution.

A problem that occurred was that when I gave the .EXE to someone else to try on their machine, they received an error dialog that read:

“This application has failed to start because the application configuration is incorrect. Reinstalling the application may fix this problem.”

When I looked at the system error log, I saw the following 3 errors had occurred:

1) Source: SideBySide
EventID: 59
Description: Generate Activation Context failed for ...\Panel.exe. Reference error message: The operation completed successfully.

2) Source: SideBySide
EventID: 59
Description: Resolve Partial Assembly failed for Microsoft.VC90.MFC. Reference error message: The reference assembly is not installed on your system.

3) Source: SideBySide
EventID: 32
Description: Dependent Assembly Microsoft.VC90.MFC could not be found and Last Error was The referenced assembly is not installed on your system.

Thanks in advance.

You need to send the runtime redistribution package to the other person and have them install it, or compile and link your application statically.

Joe,

Thanks. I didn't mention that I had the user do that because my original question was already long enough. What happened after he did that though was that the application ran, BUT it repeated the behavior that had been seen using VS 6.0 which was that the buttons and the bitmap became misaligned. When I run the app created with VS 2008 on my machine, the buttons and the bitmap stay aligned no matter what screen resolution I use.

I'm going to now have to go back and verify what happens if I run the original executable created with VS 6.0 on my machine.

As Chris says, ASCII is a standard coding and you can't change it, we won't let you. Suspicious | :suss:

However, are you asking if you can change what is actually displayed when you print a particular ASCII character? If that's your question, then the answer is yes. Create your own font. Check out Dingbats for an example of how crazy you can get with that.

if(0x65)
{
cout << 0x66;
}

this is the way, but only hollow

like that,
65 means A ? YES
and 66 means B ? YES
now when we change it 65 will B, 66 mean A

but how ? Confused | :confused:

if we take a file which s called ascii table, let change something on it Wink | ;)

but ı couldnt see anyhing for now. ı just think

maybe its trivial and unused but something we should do that to me.

So clarify for us what you're trying to do. Is it when you execute the following line:

printf("%s", "Foo");

You want to change something in the OS so that the following output is produced?

Xyy

Do you mean to display like?

cout << (char)0x66;

Also 66 is 'B', 0x66 is not! 0x66 is 102, which is 'f'.

Or, do you a string-array, and want to manipulate it?
