Hi All,

I've got a workspace style app (MDI), with a CDialogBar derived window containing a tree control on the left (for navigation, opening views, etc), and a CDialogBar derived window containing an edit control on the bottom (for messages), which sort of looks like the Visual Studio workspace. On exiting the application, I need to save the window position and state of the docking windows. How do I do this?

I guess can get a window rect with GetWindow?? soething or other, but how do I get the docked/undocked state of the window?

Thanks in advance,

Aaron

Have a look at

SetWindowPlacement/GetWindowPlacement for normal windows.

SaveBarState/LoadBarState for CControlbar windows.

Max.

Hey Thanks!

That worked pretty good, so far. I found the DOCKTOOL sample searching for that as well, which has helped.

So far, I am able to save the placement of the main frame, and restore the stae of the control bars.

But, what should I use to save/restore the size of the control bars? Ie, when I close the app, the message bar comes up with the correct state, but is not the correct size.

Can I use GetWindowPlacement for the control bars? Or do I need something like GetWindowRect/MoveWindow?

Thanks Again,

Aaron

richedit control--AfxInitRichEdit

AfxInitRichEdit();

I put this in the app class in an MFC MDI.

Now I have just a CDialog based app, and if I dont put it in, i dont get anything.....

Where should it go?

Appreciate your help,

The dialog based application still should have a class derived from CWinApp...put the AfxInitRichEdit call in the app's InitInstance function

Wrapping around font in CEdit

ns13-Jan-03 6:03

13-Jan-03 6:03

I have a CEdit with multiline and hScroll and VScroll but the contents arent wrapping automatically . How to get this to happen? Do I have to use a richedit control if I want to wrap contents? Surely there must be a way to wrap stuff around in a plane old CEdit...?

Appreciate your help,
ns

Have you tried the styles ES_MULTILINE, and ES_AUTOVSCROLL?

Those two alone should do the trick.

This is, I think an M$ feature! it is documened in the MSDN, here is a code snippet of mine from an old prog, in OnVScroll method

   // OnVScroll does not pass in a 32 bit value for nPos<br />
   // the UINT can also be -ve!! So DIY!!<br />
SCROLLINFO		info;<br />
   // Get the real position of the tracker<br />
info.cbSize = sizeof(SCROLLINFO);<br />
info.fMask = SIF_TRACKPOS;	<br />
<br />
GetScrollInfo(SB_VERT, &info);

Scrollbar range

When I use the SetScrollSizes() function of a CScrollView, it accepts a 32-bit integer... ok... but when I scroll the scrollbar over 32767(Seems to be about there), the scrollbar warps back to the beginning and stays there... why? Is that the limit it can have?

Only tested it with vertical scrollbar, btw.

Creating tables

I am aware of programs like Grid Control that allow you to deal with cells. However, I want to write my own source code that creates tables and that allows the user to edit the contents of a table. Simply, I need to create some excel-like cells. Can anyone tell me what windows functions I can use for that?

none

Handling default cut/copy/paste in CEdit control

Anonymous13-Jan-03 4:30

How can we handle the default pop-up menu (rbuttonclk) option in case of CEdit control.
I have a CFormView with some dialog controls.
When I do right mouse button click on the selected text of CEdit control it shows default popup menu(Undo/Cut/Copy/Paste/Select All Menu). I want to handle this operation through Main menu.
How should I proceed in this case. How can I know the text is selected(for copy), or clipboard is already having some copied text(for paste)?

Thanks in advance,
- Vijay

"Cut/Copy/Paste" are already in the main menu (Edit).
Examine the members of CEdit to get the selected text.
See MSDN GetClipboardData for clipboard operations.

there is a common sense for this sort of questions.

menu command goes to WM_COMMAND, override the message, click menu-item u want to handle, to see what the menu id is, then "case the_id" to handle it.

popping windows up top and behind. Cna this be done?

ns13-Jan-03 4:19

13-Jan-03 4:19

In my MFC MDI project I've got two views V1 and V2.

V1 spawns two modeless CDialogs. C1 and C2

Now I do a switchview and V2 is showing in the mainframe.
C1 and C2 remain floating on top of V2.

I want V2 to be on top of C1 and C2.

Now I switchview back to V1.

Now I want C1 and C2 to be back on top of V1.

What functions will do my first requirement?
What must I do to the already spawned C1 and C2 when I go back to V1, to make them pop up?

Appreciate your help,

You can have C1 and C2 behind the MAINFRAME, that is the Application window, but not between MainFrame and View.
Simply send them a message to set themselves to the last place in the Z-Order (or better, hide them?).

This is the normal behaviour of dialogs, sitting atop of their parent window.
Probably you have to send them a message to tell them to undo the first step.

That sounds like a plan. Now I need to know what the message looks like:

BasicallY i switchview fromn V1. So when I am doing this I sjphoulshave V1 send message to c1 and c2 right?
Something like C1->SendMEssage(" What goes here to make it hide? ")

Then in V2 whn I switch back to V1 I do again:

C1->SendMessage(" Come back into view - unhide..what command is this? ")

I guess is there something like WM_HIDE or something? and WM_UNHIDE?

I have thought about a user defined message (look for RegisterWindowMessage in MSDN, or some WM_APP+const) that are handled by the Dialogs by hiding/showing themselves using MoveWindow().

But you are right, maybe sending WM_SIZE is enough?
LRESULT result = pC1->SendMessage(WM_SIZE, (WPARAM)SIZE_MINIMIZED, (LPARAM)0);

But somehow I doubt it.
Maybe you have to search MSDN and/or Codeproject to find an examle for hiding a dialog from the outside.

Guess that will handle it
WM_SHOWWINDOW
"The WM_SHOWWINDOW message is sent to a window when the window is about to be hidden or shown.

WM_SHOWWINDOW
fShow = (BOOL) wParam; // show/hide flag
fnStatus = (int) lParam; // status flag

Parameters
fShow
Value of wParam. Specifies whether a window is being shown. It is TRUE if the window is being shown or FALSE if the window is being hidden. "

I am under the impression that neither WM_SIZE nor WM_SHOWINDOW are actually showing or hinding the window. Instead, they notify the window (its WindowProc) that it is about to be shown or hidden.

I think calling CWnd::ShowWindow() would be the way to go: It does not need more than SendMessage() needs (a pointer to the window class), but is much less work.
This would then probably result in WM_SIZE and/or WM_SHOWWINDOW sent to the window.

Activex on visual c++ 6

Hi,
I'm currently developping an activex in one session of visual c++ and so I often add some new methods, events, properties.

I build an exe project (to test it )in an other session (project) where I use the activex, and then use a Wrapper class to manage to access the activex methods...

I don't know how to upgrade the version of activex wrapper (add new added method in activex) to have the recent wrapper class version to be able to access new methods when I had some ni the activex project.

can anyone help me ?

Thank you so.
Smile | :)

Describe the wrapper. What is wrong with "#import", why do you need your own?

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
