I'm new to C programming and I need to write a "small" expandable menu framework and I don't know where to start off.
This is my task: Create an expandable menu framework in C where you can add a infinite number of entries and Sub menus containing other Menu points or where the entries refer to a external function. So far I've created the structures I need
Code:
//Menu structure
struct menu {
char mtitel[MAX];
struct mpoint point;
struct menu *next, *prev;
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
To the topic: I've been following "SDL game development" book by Shaun Mitchell and (besides the many others in the past) I've encountered a problem in one of the chapters.
I'm in "creating and displaying tile maps". The chapter uses tintxml to load data outside the code, which is used to create a "map screen".
The problem is that the program work perfect except for not loading and/or rendering this "screen".
I know this is too vague of an explanation, but I wouldn't know what else to say.
I'm leaving the link to the repository with all the code: [URL]...
So I'm trying to accomplish something that right seems to hard for it to be worth it. I'm trying to write a plugin framework/system for my game. I have read about it and everything that pops up says it's OS-specific and you have to load the plugins from either a .so file on linux or from a .dll file on Windows. So here lie my questions:
-Is there any universal way of accomplishing this?
-Every way I've seen assumes i know the names of the functions I'm calling which doesn't hold true if the plugin are written by a 3rd party. How would i turn the table on this matter?
I am trying to load a .bmp file located in the same folder as main.cpp etc. but I'm not sure what to input as the resource path so that it picks it up and, when I distribute it, I want it to be preferably cross platform and run smoothly.
I have tried using:
hello_world.bmp SDL_Game/hello_world.bmp (SDL_Game is the name of the project)
but it will work if I use the full path. I don't want to do this though, because then it will not work on other computers and platforms.
I need to show in a comboBox thats shows infor from Entity framework but i need to select a specific colum in the tables..
All in C# visual studio xaml form
So I created a var but i get and output: name of programe.NLHEntities
using (var context = new NLHEntities()) { var blog = context.EtagesChambres .Where(b => b.TypeChanbre == "Prive") .FirstOrDefault(); textBox2Type.Text = Convert.ToString(blog);// i put a text box to see what the output would be.. }
i have created application using gembox i create a word file and save data on it but i want after saving it itis opened to me using microsoft word directly
it is the code
DocumentModel document1 = new DocumentModel(); Section section1 = new Section(document1); document1.Sections.Add(section1);
I developed a sample application in EF which has 3 tables
PersonDetails, BankDetails and FixedDepositDetails.
Please find the table structure below
create table PersonDetails (PersonId int Primary Key, PersonName varchar(30)) create table BankDetails (BankId int Primary Key, BankName varchar(100),
[Code] ....
But when I run the application I get an error as
The navigation property 'Bank_Id' is not a declared property on type 'FixedDepositDetails'. Verify that it has not been explicitly excluded from the model and that it is a valid navigation property.
If I am not wrong I think I have made some mistakes when creating the model.
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?
Yes, exactly, and I have been successfully creating EF Model before from the same database.... Why is it acting up now... I did check SO and they seems not to have a solution for it also....
I would like to make a program that automatically launches and loads a file when a file of that file type is double clicked within windows. As said I am unsure where to look for some information as to how to do that, and so turn to you all. Is there a simple way of doing such a thing without using any external libraries, if so, a simple tutorial or link to a reference for this; if there is no way of doing this without externals what would be a small and simple to use library for this?
Here is a simplified version of my Menu class, where submenus can be inserted arbitrarily deep. I need to add a new functionality "go back to previous menu", which I would like to be activated by entering 0 (universal command for all Menu instances). I considered the Memento Pattern, but that doesn't seem to quite fit. add that functionality to my Menu class.
#include <iostream> #include <cstring> using namespace std; const int END = -1, NO_SUBMENU = 0;
I'm working on a project that uses type char instead of type int to make selections in a menu that calls functions. I'm really hitting a wall with the while loop, I'm pretty sure my syntax is wrong for type char.
I am using a switch statement as a menu. If I enter a non-integer value as my choice, I expect the error message , "Invalid entry", to display but instead the output keeps running.
I hate vague errors where I don't even know where to start looking for an error. Error happens immediately and it says "Unhandled exception at 0x5981c9c7 (msvcr100d.dll) in experiment.exe: 0xC0000005: Access violation reading location 0xabababab."
I'm new here! I just wanted to ask, how can I go back to Main menu using this code that I have made (I know it's not yet finish I'm using Visual Studio c++ 2010! I there are any errors in my codes

#include <iostream> #include <string> using namespace std; int pcnum[5],x; //choice pc int pc; int i; //name int y; //hours
I just started learning the basics of programming. While encountering one of the practice problems in the book by Alex Allain I got a little confused. The question is as follows:
Write a menu program that lets the user select from a list of options, and if the input is not one of the options, reprint the list.
The author assumes you can answer this question only using if statements and/or loops (while, for and do).
This is the code I've written thus far:
Code: #include <iostream> using namespace std; int main() { int option; char reset;
[Code] ....
For some reason, the nested while loop keeps repeating even when you input a valid option (1, 2 or 3). I can't seem to figure out why this happens.
I am working on a database project, which can store (initially) 10,000 marksheets with following capabilities
1) new entry 2) edit/modification of entry 3)delete entry 4) separate Departements ( BBA, BCS, M.Phil, Phd., etc.) 5) can store data on files ( initially, all data is stored in a single file)
Now, I want to create a menu, in which i can use arrow keys to navigate through the menu and use Enter key fo selection.
What should i use in it?? The project is only on C language.
I need a few pointers on how to replace the multiple "return input" in my "choice" function with a statement that perform the same action in C Programming..

But I still do not load the excel file into my program by selecting the program from ContextMenu (right click on excel file and choose program). Although if select the path to excel file from the program, the data from excel file is loaded into the program.
I'm still missing something at function OpenExcelFileWithEasyForm(). How to complete this function to load the excel file into my program when selecting programs in ContextMenu.
