Hi
I have an application where a user types a message into an edit control, after they have exceeded a certain number of characters they are shown a warning. ie AfxMessageBox("you have exceeded X number of characters");
it seems that if the user is typing fast by pressing return of the space bar this is calling the OnOK and quickly turning off the message box so the users are not seeing the warning.
Does anyone know if there is a way you can disable the return key and the space key on Afxmessagebox ? i could create a custom dialog to do this but that seems a long way round
can anyone help
thanks
Simon

You could try a few things.
1. Add MB_NOFOCUS to the flags. In theory this will not give focus to the message box, and so keyboard events will not get sent to it. There is no documentation that I could find on this, so behaviour might be a bit sketchy.
2. Try setting the default button to one that doesn't exist with MB_DEFBUTTON4.
If neither of these work, then all I can think of is:
1. Make a dialog box that looks like a message box and don't set a default button in it
2. If you want the message to have Vista/7 styles on Vista/7, use XMessageBox - A reverse-engineered MessageBox()[^] and don't set a default button.
3. Hooks. Either keyboard or API. This is a rather big way of doing it, so you would want to try this as a last resort.
I wish that more people think like you. While typing this message an update box popped up as I hit the space bar.

This sounds messy. Why not just send the edit control a EM_LIMITTEXT message?

You should initially disable the OK button and only enable it if all of the criteria have been met.

There is an option to expose C# classes/methods to COM, so you would access them from C++ in that way. Take a look at some of the articles here on CodeProject: try a search for "C# COM".

One simple solution is to create a CLI/Interop DLL compiled with /clr, this DLL can export standard C function, which the C++ code can call.
When implementing the standard C functions in the CLI/Interop DLL , then one is able to call standard .NET code, and it is possible for the CLI/Interop DLL to have references to other standard .NET assemblies.
This example hosts a WinForms control in a MFC application, but one could just aswell host a WPF control:

Then you must be doing something wrong, but we cannot guess what happens in your code without seeing some of it.

Actually i tried
CMenu *pMenuBar = this->GetMenu();
ASSERT_VALID(pMenuBar);
CMenu *pSubMenu = pMenuBar->GetSubMenu(0);
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_1, "First Item");
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_2, "Second Item");
By this i can add.but in the mainmenu already one Exit submenu is there.But i dont want that.
So i deleted that sub menu in resource file itself.And when i gave this code it shows assert error.
If i didnot delete Exit menu ,then after running application my FILE menu shows
FILE
Exit
FirstItem
Second Item

So can you not just remove it from the .rc file?

If i remove this Exit from .RC menu editor.When im runnong application it shows Unhandled Exception error.
So what i did,i coded like
pSubMenu->RemoveMenu(0, MF_BYPOSITION);
This will remove the Exit dynamically and then i added my menu by
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_1, "First Item");
pSubMenu->AppendMenu(MF_STRING | MF_ENABLED, ID_COMMAND_2, "Second Item");
Now i want to rename the main menu text dynamically.
I dont know how can i do that?

And that doesn't concern you?

Employing a "band-aid" fix is not the right answer.

How about ModifyMenu()?

You can override OnInitMenuPopup() and insert and remove menu items there.
What is happening is that your menu template (in the .rc file) is being loaded automatically. Until it is loaded, trying to insert or append will have no effect. OnInitMenuPopup() gives you a chance to modify the menu before it is displayed.

What do those two functions return? Have you tried calling ::InsertMenu() or ::AppendMenu() instead?

If the menu is already selected into the mainframe at time of modification, you need to call DrawMenuBar() after updating it for changes to take effect (be shown)
If you vote me down, my score will only get lower
