Visual C++ :: Enable / Disable Menu Item 2 In OnUpdate Handler Of Menu Item 1?
Sep 15, 2014
I have two menu items. When item 1 is disabled, I want item 2 to be disabled as well. In the OnUpdate handler of menu item 1, I have tried to use "t_pMenu = pCmdUI->m_pMenu;", "t_pMenu = pCmdUI->m_pSubMenu;" and "t_pMenu = pCmdUI->m_pParentMenu;" but I always get NULL t_pMenu. How can I achieve this purpose?
I have ploughed through the exchanges in all the forums, yet I still cannot make it work. The following is a tiny Code::Blocks program, written to isolate the problem:
case ID_ENABLE is similar to case ID_DISABLE above, and neither works. case ID_MESSAGE and case ID_EXIT both works as expected.I have tinkered with EnableMenuItem(), but without success.
I'm using this tutorial for making an owner draw menu. [URL] ...
When I go into the .rc file and remove all of the MENUITEM SEPARATORs all the menu options are squished to the left of the menu as in the screenshot. As long as there is just one MENU SEPARATOR anywhere the menu is fine. If I could make the application without MENU SEPARATORs that would be awesome.
I quite often use an ide written in assembler: RadAsm3[URL] .....
It has a menu item to explore current path. I have used other ide's that have a similar feature but:
The one in RadAsm3 will activate a current Explorer window if the current path is the same as the one requested. All others open a new Explorer window.
I would like to implement the RadAsm3 approach using Visual Studio 2013 Community c++ as my host compiler for testing.
I tried to get the title of current windows but it appears ShellExecute "explore" does not produce a conventional window???
I know how to add a new item to a folder right-click menu, using the registry, but it won't show up on file right-click menu. give me a link to how this is done? I want this new menu appear on every file R-C menu, file registered with the system or not. Is there a simple way to do this as adding a item to folder R-C menu, or will i have to iterate all the registered file types in registry to do it. I tried google with many search terms, but i can't find a source for this.
I am trying to write a menu program that will be broken down into a series of calls to function for each of the menu items. Two of the menu items will be simple programs which I wrote.
I want two of the functions to run one of the two programs I am trying to include as items in the menu.
So far I am only familiar with variables, loops, if statements, and I just learned how to write functions.
The problem I am have is that I don't quite understand how to write a function that will run one of the two programs. Also I am having a hard time writing the program in away that would allow the user to select the menu items.
I'm creating a program that is based on a menu system. Basically each menu is its own user-defined function. The problem is at each menu you can input 'b' to go to the previous menu. I just have it call the function of that menu.
However, do the functions need to complete themselves eventually? If I just keep calling functions will I just keep going further and further deeper into ever running functions?
If so how do I avoid this and yet keep the option to go back to a previous menu/function?
This is what I have so far, it gives me a nice menu to select from and it all works but after I make a selection it closes the program. I tried to return to it but it won't work for me
#include <stdio.h> int main() { int choice; int deposit; int balance = 500; { printf(" CHOOSE FROM THE FOLLOWING
i have tried to search on the Internet but haven't found a suitable result that links in with what I want to do, that is to creation a WPF application and when you press a enable button it will enable the LAN and when I click the disable button it will disable the LAN until i click the enable button again. Now I know how to creation a WPF and the buttons, but how would I do the disabling LAN and enabling LAN?
By LAN i mean just the networking adapters, so that the PC cannot connect to a router and then the Internet.
If we work with a ListView,and want implement some functions like OnLBDblClick(), we only have a CPoint, but not the column and row that this point suppose. How can i Know that, is there another type of functions that gave us the row and column?
I need a ownerdraw CListBox where I can change the item height during working with the list. The msdn says that I can specify the height in OnMeasureItem when the listbox will be created (ownerdrawfixed) or when an item will be inserted (ownerdrawvariable).
How to change the height e.g. when I click a button?
I made also some tests with CListCtrl. There I can change the height. But there is only one height for all items. How to set individual heights for the items?
I am developing a CFormView MFC app. When I go to click something on the menu, it takes awhile before the event happens. The project is build optimized in release mode. I have 3 additional threads and I thought they might be blocking the internal MFC framework stuff, but I use the Sleep() call in each thread to yield to the MFC main app.
I derived a class from CRecentFileList in order to set the number of displayed chars for MRU.
The problem is that if I open the app with 256 set for this number (it is read from .ini file) the display is correct. But after I change it to 10 for e.g., File menu width remains unchanged altghough MRU are correctly displayed on 10 (or at least file name lenghts) chars.
how can I tell to the menu to shrink to actual width?
I want create menu button to change font of CString displyed in main window. We can see string "SAMPLE",and when i press menu button that i created i want to string "SAMPLE" to display with different font,i already created CFont object and added italic style with CreateFont;
This is my menu function:and CString m_text and CFont font1 are declared in FesbDoc.h
I have a (large) application that works perfectly under XP. When I run it under Windows 7 the "File Edit View..." menu in my application flickers when everything is otherwise idle.
I have traced this down to SetTimer and its associated OnTimer function. OnTimer usually does nothing, so I have commented out everything leaving this:
Code: void MyView::OnTimer(UINT nIDEvent) { }
I have also changed the SetTimer call to give one tick every five seconds.
I now see the same behaviour: the File menu is very briefly greyed-out every five seconds, leading to the flicker. Nothing else in the window is exhibiting this flicker.
So, I have a call to a null function every five seconds that manages to affect a menu.
I'm attaching a project that demonstrates the issue. I need to display a context menu with anti-aliased bitmaps. I wrote my own method to convert an icon into a bitmap (see the CreatePARGBBitmapFromIcon() method) but the resulting bitmap seems to lose all anti-aliasing when displayed in a menu. What is interesting is that the same bitmap is displayed without any issues in a CStatic 'stPic1' control (the one in the middle.) The visual artifact also seems to be different on different OS. Take a look at the screenshots attached.
