C++ :: 2D Side Scroll Game - Background Is Not Working Right
Dec 30, 2013
I am working on a 2D side scroller game. Where a ball is moving continuously towards right . I used a camera to follow the ball as soon as ball reaches the center of screen. I created a horizontal line to look like the surface on which the ball is rolling.
line runs from x=0 to x=800 (i.e screen width)
NOTE: (0,0) coordinate is at top left corner of display.
Problem: My display is 800 x 400 . Camera follows the ball, but soon the ball crosses x=800 and starts moving in black background. I want that line surface to stay there instead of going out of bound.
Additionally! I generated obstacles from x=800 which also move out of bound along with my line.
What should be done here? This is just my first c++ game project, so i might be skipping things that can solve the issue.
[Update] these screenshots manage to show, what the real problem is: [URL]

I want to have an animated background for my games logon screen. However sprite sheets only support an image size of 2048x2048. So my question is sense the background is 640,480. Would it be logical to use a video as the background and draw GUI components over the drawn video frame?

I am relatively new to C programming, and I am encountering numerous issues with this program that I cant seem to figure out how to fix.
First, when the user selects the arithmetic game, I keep on getting different incorrect answers from the arithgame function. For example, when I am presented with the question 3+2=_, sometimes the function claims the answer is the first number, 3, and other times the function gives me a multiplication answer, 6. This happens in both the addition and multiplication parts (ie. the multiplication answer will either be the first number or the addition answer).
Additionally, I cant figure out why my guessing game loops forever, rather than letting me guess until I get a correct answer.

I wrote a Simon game, and wanted to save the top 10 scores. I was working right, until I decided I wanted to still be able to read the file if someone enters a name containing spaces. Now, the results aren't right.
void FillScoreList(string Simon_Names[], int Simon_Scores[]) {
ifstream Simon_HiScores("Simon_Data.txt");
if (Simon_HiScores.is_open()) {
for( int x=0;x<10;x++){
[Code] ....
Even without trying to read names with spaces, I'm getting
dad 1
0
340176
0
... either a long number or a zero. No names

On a right angled triangle, if the user inputs only ONE side length (not the hypotenuse) and only ONE angle, what code is required to work out the hypotenuse? I know how to work out the final side and the remaining angle once I have this.

I know this question must have been asked before, but the problem that I am facing is that I am using a library PoDoFo to parse PDF files. It seems that it is only compatible with C++.
Now I want the application to be web-based. That is, the user uploads a PDF file on the server, the server parses it and the parsed content is then sent back to the user.
Is such a thing possible with C++, or maybe any good work-arounds? Or should I look at server-side scripting languages like PHP and their respective libraries?

I want to make something like this for a game:
It is a "list box" that has 2 scroll buttons (scroll bar not needed). One button push, "scrolls" the list one entry.
Needs to run crossplatform (windows, linux).

How do you add a value to the beginning of a string instead of the end?
This is for an assignment and I have to convert the user input (always assuming its a valid decimal number) to binary and store it in a string. I've got up to dividing by two to get the remainder ...

im trying to code a simple list box for my self made GUI but i seem to be stuck at the scroll bar. I already finished with the calculation for the scroll bar size but how I could calculate it's current vertical position depending on the current item on top of the list box.
My current code looks like this
ListBox struct:
struct MenuListBox {
int PosX;
int PosY;
int Width;
int ItemsVisible; //Items visible at the same time
int CurrentItem;
[code]....
Additional vars in the menu class:
MenuListBox* MenuListBoxes;
int ListBoxCount;
How could i calculate this:
New->CurrentScrollBarPosY = ; ?

I have an emulation project I've been working for a long time (the Altair32 Altair/IMSAI emulator) and I'm trying to simulate a dot-matrix printer for list output in CP/M.
Here's what I have so far and where I'm stuck and need a push in the right direction. I'm using a dialog box with a green bar paper bitmap as the client area background. I used CreateFont to load a dot matrix printer TrueType font and have the base code to print on subsequent lines. So, based on the dialog size, font size, etc., I get about 10 lines of dot matrix printing, 80-characters wide. So far so good.
The problem arises in how do I scroll the text like on a printer? I thought about trying a static text control or an edit box, but the text to be printed is of an unknown size and ISTR that both of those controls have finite size limits (32k but maybe I'm wrong). They would also need to be transparent so that the green bar paper shows through.

According to my project instructions, I have to make a "validation on the delete button, that before a record can be deleted it will check to see if the count of "In-Progress" orders for that product is 0. If it is greater than zero, it should not allow this record to be deleted."
So far I have on the code behind page:
protected void btnDeleteProduct_Click(object sender, EventArgs e)
{
DataView dv = (DataView)SqlOrders.Select(DataSourceSelectArguments.Empty);
[Coe].....
The professor said I have to: "As for getting the count, check your notes and book, specifically looking at SQL and the Aggregate functions. There is a function we talked about in class called "Count(OrderID)" and set the where clause to check for the productID.

For a ribbon bar with edit controls (CMFCRibbonEdit) I want to handle the mouse scroll events for the edit controls. That is, when the user clicks and then scrolls on the edit it will navigate a predefined list of strings. I want to capture the scroll event in order to update the edit text step by step.
This kind of behavior is implemented by the Spin Edit; I don't want to use the spin edit control since it only uses a list of integers and the spin buttons are too small.
Is there a way to catch the mouse scroll event for the CMFCRibbonEdit control? How to approach message handling for the ribbon (other messages than the COMMAND allowed by the ribbon designer). I'm using VS2010 on Windows 7 and the ribbon was designed with the ribbon designer?

Right after I close FIFO on the producer side, the app on the consumer side gets into an endless loop. select() returns that FIFO is ready to read. Below is the excerpt from the consumer code. The FIFO is opened "blocking" on both ends.
Code:
FifoClass fifo_r = FifoClass("/tmp/FIFO_READ");
int fdr = fifo_r.OpenR();// this->fd = open(name.c_str(), O_RDONLY , 0);
for(int i=0; ;i++) {
FD_ZERO(&rset);
FD_SET(fdr, &rset);

I have a question concerning the CDialogBar (:CControlBar).
I have a MDI application with a dockable toolbox (CDialogBar).
The user is able/allowed to move the DialogBar and to dock it at the right or left side When I dock at the left side, the content of my mdi-application (so all other open windows) are moved right (so the dockable bar moves the windows).
If i dock at the right side, nothing changes.
How can I change the behaviour of the bar, that the windows inside the application keep the same position when I dock left ?
(Problem is, that my windows are aligned on the right side of the application). When I dock the bar on the left, the windows are getting moved in the not visible area.)

I'm still at the very beginning of learning WPF and there are still countless things i don't fully understand. For instance, as I can see in my WPF project, there isn't an event that would fire when the Background property of some control is changed. Or am I just missing it? If i'm not blind after all, and it really doesn't exist, is there any way i could get notified when the Background color of some control is changed?

Okay, I have a form and I have a tab control thing. On the second tab, I have a button which is supposed to turn the background green.
So, I have this:
#pragma endregion
private: System::Void greenButton_Click(System::Object^ sender, System::EventArgs^ e) {
this ->BackColor = System::Drawing::Color::Green;
But clearly that just turns the FORMS background green. How can I change the TAB background to green.
