Howdy - I've got the code I need to add and remove menu items that I need, but I'm not sure where to place this code.
Using an SDI MFC app, what message do I handle to know that the user dropped down a menu in the main menu?
Thanks!

Please, try out WM_INITMENUPOPUP. It is useful to modify popup menu at runtime

I guess I overlooked that one, Thanks!

My application is MDI application.
So,I cannot know what parameter use in following code???
m_tabPages[0]->Create(CMyTabDlg,this);
>>>>>>>>>>>>>>>This is my error>>>>>>>>>>>>>>
MyTabCtrl.cpp(54) : error C2275: 'CMyTabDlg' :
illegal use of this type as an expression
MyTabdlg.h(13) :
see declaration of CMyTabDlg'
>>>>>>>>>>>>>>>This is My code>>>>>>>>>>>>>>>>
//MyTabCtrl.cpp
CDialog *m_tabPages[2];
//MyTabCtrl.cpp
void CMyTabCtrl::Init()
{
m_tabCurrent=0;
m_tabPages[0]->Create(CMyTabDlg,this);
//what i use parameter
m_tabPages[1]->Create(CMyTabDlg,this);
//what i use parameter
m_tabPages[0]->ShowWindow(SW_SHOW);
m_tabPages[1]->ShowWindow(SW_HIDE);
SetRectangle();
}
//MyView.h
CMyTabCtrl m_tab;
//MyView.cpp
void CMyView::OnInitialUpdate()
{
CFormView::OnInitialUpdate();
m_tab.InsertItem(0, _T("One"));
m_tab.InsertItem(1, _T("Two"));
m_tab.Init();
}

As I thought, CMyTabDlg was a class name, not variable name, so that, it is illegal to appear as a function argument.
|
|
|
|
|
//CMyTab
//MyTab.h
CDialog *m_tabPages[2];
//MyTab.cpp
m_tabPages[0]->Create(CMyTabDlg,this);
My demo is MDI application.
i have a class.This is CMyTabCtrl,
i found codeproject web site.
this demo is dialog base application.
i run this demo is ok.
and i making mdi application.
and use this class.
but i don't know.what parameter place in
"CWnd* pParentWnd".
>>>>>m_tabPages[0]->Create(CMyTabDlg,this);
>>>>>function argument(CDialog::Create)
BOOL Create( LPCTSTR lpszTemplateName,
CWnd* pParentWnd = NULL );
|
|
|
|
|
BOOL Create( LPCTSTR lpszTemplateName, CWnd* pParentWnd = NULL );
In this case, the first argument typed string?
|
|
|
|
|
Yes!!!
i change.................
m_tabPages[0]->Create(IDD_MY_DLG,this);
thank you so much...........

I assume you mean Gauss-Jordan elimination, but I wouldn't do it that way. It works, but it's very unstable. A much safer way would be to use LU decomposition.

When I try to modify the afxcore.rtf or afxprint.rtf for any reason, for example, I try to replace <<your app="">> with the name of my app the modified rtf file won't compile. Help workshop gives a couple of compile errors when I compile the hlp this way.
I open the files as rtf's in Word and save them in Word.
Anyone else out there have this happen?
Is it a MVC++ problem?

1) What are the errors?
2) Are you sure you're saving the files in Rich Text format, not Word's native format?

All,
I am working on a project to simulate a Jungle using C++. Being a 'non-graphics' coder, I am having a hard time envisioning a nice, easy way to graphically represent this Jungle simulation.
A little background:
The Jungle contains a few different kinds of animals which Move, Attack, Defend, Breed, etc.
The Jungle must be a simulation of the interaction of the animals...2-dimensional is recommended
Now, I am OK on the code for the interaction and the storage of the classes and all that...but, since I am a 'non-graphics' coder, what would you all suggest the 'best' option for me to graphically simulate these 'animals' (i.e. E's for elephants, M's for monkeys) moving around in this Jungle (in Windows, using Visual Studio 6, C++).
I could technically work with an array of characters that changes as the symbols that represent the animals move around, fight, breed, etc and simply print that to the standard console...but I am not sure how well ths works in a Windows Console. I know with Unix, I could use cursors or something like that to make it look nice (doesnt just continually scroll and display, scroll and display each time a day goes by in this sim). Is this the easiest option? Will this become a factor after a long enough running simulation (like 1000 sim-days of movement/breeding/fighting)
Is there a better way with forms/panels/datagrids? I am simply looking for suggestions on how to best use VC++ and Visual Studio to show the symbols moving around in a grid-like (2-dimensional) environment that wont cause me huge headaches and that is relatively simple to develop. I dont have all the time in the world  .
Any input is greatly appreciated. Thanks!!!!

Direct Draw. Then you can just create a bitmap that contains all the images you need, and draw the bits you want in the right places.

I am not sure I understand 'Direct Draw'?
Also...can these symbols be moved on the bitmap alot? They need to move alot...prolly each item needs to move about 1000+ times...
Thanks!

I think Direct Draw would be good to handle so many moves. Another option is OpenGL.
Have a great day ahead!

Google is your friend. Direct Draw is part of DirectX.

Much as you like - knock yourself out. Open GL is for 3D, that's a ton more work that Direct Draw ( 2D ).

Thanks -
I will look into Direct Draw.
I appreciate your help. I may call on you again should I get stuck with the graphical widgets.
Greatly appreciated!!!

Alright here is the situation...I want to have an MFC image frame that when you drag a picture from a web site or hard drive onto the frame the program copies the image to a selected folder and displays the image in the frame. I found the option to accept files but i don't know what to do from there. Any assistance would be helpful. Thank You.

I have this program I made to do some stuff I wanted. It uses plain win32 (no-MFC) and draws a bitmap in a window. Well, at first I was just using normal GDI and StretchBlt and it worked perfectly, but I wanted bicubic interpolation so I converted it to GDI+. So it basicly works fantastically and looks much more crisp, but for some reason the redrawing is highly erratic. When it needs to redraw (after another window was hiding or something like that), it sometimes work but more often it doesn't work and just displays an empty window. Sometimes, however, you can see the image flicker as the window gets unhidden and then the image immidiately disappears. Also, when you would move the window so some of it is out of the monitor's bounderies and then move it quickly into show again, the image would have empty reigons that do not get redrawn even after letting go of the window. And it's not just the image: If I make it also fill a rect on the whole client area, it would have the same erratic behavior. So, it's not just the image. Is GDI+ known to have these oddities when redrawing? I haven't updated my GDI+ libraries or DLLs; My DLL is just what came in XP and my libraries are just what came with VS.NET 2003. I'm starting up GDI+ and shutting it down all just fine, and I link everything just fine and I don't get any unresolved externals or anything, and it does work, except for this weird redrawing issues.
Any help would be much aprreciated. Thanks.
