My guess is that Notepad opens the file for reading only (and only tries to open it for writing if the user wants to save, at which point it will also fail), when Excel or Word or the likes opens the file it probably allows other processes to read the file, but not to write to them (this would explain how you get a "open for reading only" option from Word if you try to open a document that is opened by another word instance/another user's word...). Can it be that when you use CreateFile to open the file you try to open it for writing?

Maybe the same difference there is between a C++ forum and Google.

are you scrapping from custom window or generic window?

hi i want to move button control on mouse LButton down with no Resize and position must be saved within the dialog.
How it can be done.
|
|
|
|

First, commas, full-stops and semicolons has a meaning also in natural langage:
Your question can be:
"hi, I want to move A button control on mouse LButton down, with no Resize; position must be saved within the dialog.
How it can be done?"
or
"hi I want to move button controls on mouse LButton down with no Resize and position. Must be saved within the dialog.
How it can be done?"
And they are quite different questions.
Assuming the first, since a control is a window, just use MoveWindow (note: mouse coordinates are obtained in screen coordinates, while move window requires parent client coordinates, so do the proper translation with ScreenToClient).
I don't understand what you mean with "saved within the dialog": if you mean "saved within the dialog RESOURCE", then give a look to http://msdn.microsoft.com/en-us/library/ms648004(v=VS.85).aspx[^].
Consider also that, unless you are writing a "resource management tool", modifying the resource result in modifying the "exe", and this is not, in general, a good idea: what does it happen if multiple users attempt to to modify your "exe" if it is shared across a network?
It is better to save the control positions in a file stored in a user specific directory (you can get the path with SHGetFolderPath, giving CSIDL_APPDATA as a CSIDL) and, when loading the dialog, change the controls positions (again, with MoveWindow) accordingly to such file (if existent) before showing the dialog.

Use MoveWindow [^] or SetWindowPos [^].

To make new position persistent, you may store coordinate values in a configuration file.

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)
{
if (m_bDragging)
{
CWnd *pParent = GetParent ();
MapWindowPoints (pParent, &ptMouse, 1);
CPoint ptDelta = ptMouse - m_ptMouseLast;
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.

AFAIK there's no magic for that: you have to rebuild properly the list.

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

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?

Problem is, I can't see any way to put something on the title bar of explorer using this.

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.
