Problem:
I want to create a class in the static lib that has an unknown base class . Unknown means it must be a CWnd or CView or a class derived from one of those. The reason is so I dont have to maintain the code in multiple classes as I want to use the class in a CView derived class and CWnd derived class, but another person needs to use it in a CBaseView derived class and a CBaseWnd derived class. The problem I have come across so far is the message map and the IMPLEMENT_DYNAMIC macros. Any Ideas? Open to sugestions for a better solution.

I have a RichEditCtrl that "initially" does not diplay text that is pasted into it (using my_RichEditCtrl->Paste() or by Shift-Insert,Ctrl- V). The text "is" displayed if you then obscure the window and cause a redraw.
What do I have to do to get the text to be made visible after the paste? Is it something to do with the configuration of the RE Ctrl, e.g in the Create call, or something I must do after the paste?.
Thank-you
Steve

I found that calling
m_pMyRichEditCtrl->RedrawWindow();
does the trick but why? What's going on? Are there others ways?

I still have a problem..
The processing behind the "Paste" button in my application is simply:
m_pMyRichEditCtrl->Paste();
m_pMyRichEditCtrl->RedrawWindow();
which solves the text not visible problem from the button but it does not solve the same problem when I paste using Ctrl-V. Any idea what else I need to do?
Thanks

Make sure you have handler for Ctrl+V and it pointed to your function that does Paste(); RedrawWindow();

I'm having some frustrating issues and I'm hoping that
someone can help me. I have two apps created by VC++6.0
that have an Access database, they are data entry and data
search apps. The code internally is arranged, in the data
entry app, so that it is in edit mode for maybe a 1/10 of a
second as it copies local variables to the dataset and
updates it. However, while the entry app is being used the
data search app (when started up) get an error message that
says 'Couldn't Update; currently locked by user admin on
machine <machine name="">'. Now this just started recently, I
checked the mdb file itself under
[Tools->Options->Advanced] the 'Default Open Mode' is set to
Shared, and the 'Default Record Locking' is set to No
Locks. What would be causing this?? I really appreciate
any help someone might have with this.

Does anyone have experience with keyboard hooks?
I have created a keyboard hook and it works just fine provided the exe driving the dll displays a dialog box with an edit control and the edit control has focus.
However, if another app has focus, say Notepad.exe, then the keyboard hook never receives the messages.
What I think I need is some way to force the keyboard hook to the top of the message chain.
I would like to start a dialog with anyone that has worked with keyboard hooks before.
Thank you.

Are you using SetWindowsHookEx? If so can I see a snippet of the code you are using?

Here is the
ghHook = SetWindowsHookEx(WH_KEYBOARD, &KeyboardProc, ghInstance, NULL);
Since I reported the problem, I believe I have found an answer.
I am using
SendMessage(ghWnd, gnKeyMsg, wParam, lParam);
to get information out of keyhook.
This dll attaches itself to every process in the system. One dll but many memory spaces.
The problem is only the exe that launches the dll sets the value of hgWnd, in all other memory spaces it is NULL.
I think what I need to do is set this value in the registery and read it into each memory space.
What do you think.
Thank you.

Hi,
you can use universal message filters and look for keyboard messagers. I tried other ways too, but no one works. I the sample file you can replace ::GetCurrentThreadId() by NULL to have a system-wide filter.

Hi!
I need to combine a stored bitmap (>= 256 color) with some graphic elements (e.g. lines, text, ...) and save it as a 256 color bitmap. Do you have any code to reduce the color depth of a bitmap (because this is the real hard thing for me)? Thank you in advance!
Ciao,

Hi all,
I have a Dialog based app that creates a Modal Dialog Box
that then creates some modeless dialog's.
What I need to know is when a modeless dialog exits,
I wish it to pass a message back to the Modal Dialog when the modeless dialog Box has been finished
with a EndDialog.
Sorry for this being a simple question. But I have looked through a stack of samples, And couldn't find an example of this being done.

You could pass a pointer to your modal dialog up to its child modeless dialog. Then place a function in your modal dialog that will allow you to set your message. Then from your modeless dialog you can call that function before you call enddialog.

Colin,
Do not use EndDialog() with Modeless Dialogboxes. What you need to do is override the OnOK() and OnCancel() methods and call DestroyWindow(). As for passing a message back to the parent dialogbox, all you need to do is have a "MyParent" variable and do the type cast back to the parent class.
Ex: (( CYourClassHere *) MyParent)->VariableOrMethodHere;
** Note ** : This assumes that your dialogs are CWnd based.
- Mike
P.S. - Any other questions - drop me an e-mail or pop a rely to this message ...

I have a dialog based app with three listboxes. I used AddString("") to add several items to
each string. When I run the program, it allows me to select all the items at one time. I
want the user to only be able to select one item at a time. How do I do this?
Thanks,
Stephanie

Hi,
If you create list boxes explicitely using create function then make sure that you didn't specify LBS_EXTENDEDSEL or LBS_MULTIPLESEL style.
If you use dialog editor for creating the template for your dialog then you have to display a property dialog for the list box control. On this dialog you have to select the second page "Styles" and in the "Selection" combo box you have to choose "Single" item

I had "Single" selected. It makes the list box gray (instead of white) and won't unselect
item. ie. The default selection is String1. If you click on String2, both are blue. If you
click again on String1, it stays blue. It's impossible to select only one string, unless you
take the default. I'm not sure what's going on.

I just figured out what it was. In an earlier version of the dialog box, I was changing the
color. I don't need that anymore, and when I took out the code, it started working as it
should.
Thanks for your help!

I am using VC5. If you place a Rich Edit (RE) control in a dialog from the controls toolbar and bring up the class wizard the RE control ID is not listed in the list of member variables. Is this correct? How are you supposed to exchange data with the RE control? The object ID for the RE control does appear in the Message Maps tab of the class wizard. Do I write handlers (as required) for the 26 NM_ and EN_ messages listed? Do I manually add a CRichEditCtrl member variable to the dialog class?
Thanks again for any help supplied
Steve

This is probably due to the fact that the ID is not yet linked with the dialog. If VC5 works the same as VC6 in the resource editor, hit ctrl+w after clicking on the richedit control...it should automatically bring up the RichEdit ID in the box (then, make sure to select the dialog class, if it is not already selected, so that your inserted functions go in the right class).

How can I reload explorer.exe through C++?
I need to do this so it rereads the registry.
Thanx.

I remember seeing how to do this in "Visual C++ Windows Shell Programming" (a cool book BTW). The topic isn't in the index (and I'm not really up for searching through 660+ pages for it) so this is from memory...
I believe you get the HWND of the window with class "Program Manager" and send it a WM_CLOSE. Then re-run Explorer to restart the shell. The only trouble with this is that some of your tray icons will be blown away.

Ah, I found it after all!
HWND hwnd = FindWindow( _T("Progman"), NULL );
PostMessage( hwnd, WM_QUIT, 0, 0 );
ShellExecute( NULL, NULL, _T("explorer.exe"), NULL, NULL, SW_SHOW );
