C++ :: How To Retain All Project Properties When Change From Debug To Release Mode
Aug 1, 2013
I'm developing C++ application in visual studio 2012. I have couple of C++ projects in my solution. I have put some library paths in every project's properties ( i.e ,Config properties - > C/C++ - > Additional Include Directories and Linker - > Additional Include directories ).I developed in debug mode, if i change to release mode, all library settings gone.Is there any possibility to retain all settings when change to debug to release mode and vice versa ?
i've got an assigment that requires me to overload some operators and add some objects together.
I will show the code and explain as good as I can.
void SArray::operator+= (const SArray &obj) { Sphere * tmp_arr; tmp_arr = new Sphere[obj.antalobjekt+this->antalobjekt]; //antalobjekt = //Gets amount of elements in the arrays.
[Code]......
m_arr is the inner array for storing elements, do ask if something is not clear enough. The copy constructor works, so i have not included it.
I am getting some weird errors while building in release mode. It works fine in debug mode. Libraries and includes are linked in both debug and release version, but it's acting like it's not.
I get this error when i try to run this code for an inventory in debug mode in VS. But for some reason it works just fine in release mode.
void Push_Back_Item(Item *item){ for(int y = 0; y < InvSizeY; y ++) for(int x = 0; x < InvSizeX; x ++){ auto Iter = ItemList.find(std::make_pair(x,y)); if(Iter != ItemList.end()){ item->SetDead(); // ERROR } } }
This isnt the full code though but it still gives me the same error.
The only thing "item->SetDead()" does is to set a bool to true.
This is the map i get the iterator from std::map<std::pair<int,int>,Item*> ItemList;
This have been bugging me for quite some time now.
Kinda like in properties, where you choose the height and width of the window, but in actual code. So everybody who open my program see the same window.
I have researched quite extensively, experimented, and still cannot seem to change the properties of a control on an active winform from a user control.
So I have a user control which populates each dynamically added tab page in a tab control.
I have a textbox in the user control which I would like to type in, capture the text_change event, and change the text of the label in the winform.
i am just making some new programmings and testing it. But every time after compile and run The dos window is closing and again I have to compile And run command so i want The dos windows should prompt me for next input rather than closing.
I am trying to release my C++ app to run on desktops that dont have VS installed and have created an install shield app to install on the desired computer. my issue is even after packaging it, it still requires certain DLL's...I read online that I had to copy 'msvcr120.dll' and a few others to syswow64 and sys32 folders but now when I try run my app it just crashes before starting.
I think it sucks that Microsoft no longer packages required DLL's like it used to in 2010.
I have a project which does a specific thing, like an open file dialog.
I would like to open it in a different project on a click of a button.
Also, It has a different namespace.
I'm guessing that it would involve a "using" statement to add the namespace And I will have to add reference to an *.exe or *.dll -> I'll have to look up how to make a *.dll, I know where the *.exe file is.
I have searched for a different things on Google, but I don't think that I am looking for the correct phrase (which is always frustrating...)
Is it possible to access file properties from c++ program? For example, user could drag file to program and then it displays a detailed information about file like date modified, size, type and etc..
I have startes making a game where there is 3 ships that cross the screen verticaly, and the point is to shoot them down. So far I have actually managed to do this. I have also managed to add gamescore to the ships. But here is my problem, I cant find a way to combine the score from all three ships in to one score. I have all three ships in different classes, is that wrong? When I try to combine the scores, ship score1 cant see the other scores.
Do I need to somehow have all the ships in one class. Or are there a way to read the scores from three classes, and adding them up in to one in a new class?
One of the errors I get is "the name 'score1' does not exist in the current context.
I've been attempting to design a multiform WFA in Visual Studio 2010, but I'm so rusty with the language it's hard to remember how to do a lot of things, especially when it comes to visual programming, which my class only partially covered. I've never made a multiform application before, and my problem essentially boils down to how to pass data between forms.
My application is a simple item list and order form, sort of mimicking what you might see on a site like Amazon or eBay. My first form contains a drop down list and 'checkout' button. The dropdown list has been populated with an object collection, each object holding the product's name and price.
public partial class Form1 : Form { //Item class for dropdown menu public class Item { public string Name; public decimal Price; public string itemName
[Code] ....
When the 'checkout' button on form 1 is clicked, I want the Price and Name properties of the selected droplist item to appear in a pair of text boxes on form 2 for the purpose of lowering the user's cognitive load (if they can see what they've selected, it's one less thing to remember).
I've seen plenty of tutorials on how to send a textbox Text property between forms, but none for how to do this. As I said, I'm rusty with the language, and I'm pretty sure there's a better way to set up my combobox items, but I can't remember how to set it up.
public class MyClass { public int age { get; set; } } static void Main(string[] args) { MyClass testing = new MyClass(); testing.age = 44; Console.WriteLine(testing.age); }
output: 44
Code using regular variable declaration:
public class MyClass { public int age; } static void Main(string[] args) { MyClass testing = new MyClass(); testing.age = 44; Console.WriteLine(testing.age); }
output: 44
Why use the auto-implemented property when you can just as equally use the second code block to achieve the same thing?
I had written a "DLL" in VB.NET a year or two ago to read and set MP3 tags. I want to write this exact same library in C++ so I can convert it in my droid project, and to get a hands on introduction to C++. So far this attempt has been a total mind melt!
I am finally wrapping my head around .cpp and .h files so there is light at the end of this tunnel. Here is my problem now:
I wrote the VB project with properties for each tag in the MP3 file, then I could get and set them - easy stuff.
When I try this in C++ I get compile error: a property can only appear within the definition of a managed type. I can usually stumble through Google searches and figure out this type of stuff on my own, but this one is stumping me -- I think I am missing some fundamental stuff here.
My code:
// MP3Tags.h #pragma once; #include <string> using namespace std; using namespace System::IO;
I have been trying to make a custom control(list box with more features). I know how to setup custom properties, but how do I make it so that the property can be edited in a separate window ?
I think I figured out how to show the form itself, and I don't know how to make the [...] button like :
There's not much Custom Control tutorials out there, and that's really the problem here.
My coin/money change code works when there can be an exact change each time, i.e. when the 1 cent option is available. However, when the change options are only $10, $5, $1, 25 cents and 10 cents, it does not give me what I want for instance, I wanted to get change for $237.80, I was expecting to get:
23 10's, one 5, two 1's and 8 dimes. However, the code below is giving me 23 10's, one 5, two 1's and 3 quarters (there is no option left for the 5 remaining cents).how to fix it?
Code: #include<iostream> #include<algorithm> #include<vector> using namespace std; void change(double cents, int a[]); int main() { double Dollars; double cents;
Well I know how to pass values between forms using get and set properties. But the problem with it is everytime I want to pass values from form2 to form1 it doesn't appear. To make it appear I have to type form1.Show(); which open form1 a second time and then show the value. Is there any way I could make it appear without using form1.Show();?
I'm trying to get my head around threading and gui applications for fun, and I've ran into a problem I'm not too sure how to google it correctly or I don't understand the answers given. Basically I'm trying to access GUI item properties (add to a listview). I've been on stackoverflow alot, and I've noticed that accessing these properties is quite difficult. At least, I'm not really understanding how it is supposed to be done.
The following line gives me a null value.
frm.lstChat.Items.Add(newList);
From what I understand I need to access my form object instead of creating a new object window... but I'm not sure how to reference the initial form application.
using System; using System.Collections.Generic; using System.Linq; using System.Windows.Forms; using System.Net.Sockets; using System.IO; using System.Threading; namespace ModBot {
How can I write my own container which has properties of both vector and list.
E.g. I can access elements directly using [] operator like vector and behave like list in terms of memory (means we don't have to shift elements if we want to insert in between like list)....
I want to make such application in which user make directed graphs along with relations between them. After that application show that which graph properties are proved in this graph e.g Reflexive, Irreflexive, Symmetric, Anti Symmetric, transitive etc
How would you create a video game in c++? I'm not sure really how to display the graphics and set properties and do all that stuff. I don't have money to buy a book about so how do you?
