I'm currently reading/programming from "Head first C#" book. I have this project which is making a program that has four dogs which race and there are three players that can bet on the race. I need to learn how to make the "dogs" (picture boxes) move from left end to the right end of a picture box.
Here is the code:
using System; using System.Collections.Generic; using System.Text; using System.Windows.Forms; using System.Drawing;
I have a picture box, inside a table layout panel. The default size for the picture box is 456, 457. However, what I want to do is have the picture box be the size of the available area, even if the form is full screen.
I have the picture box dock set to fill etc. but not matter what I do, it refuses to change the dimensions from the ones above.
The only work around I could find that worked was this:
this.pbMainMap.Size = new Size(Screen.GetWorkingArea(this).Width, Screen.GetWorkingArea(this).Height);
Which is pretty useless if you are using a table layout panel. Can I grab the dimensions from the cell I am in or something?
I Was Try To Change PictureBox To The Memory Stream And Then I Read Memory Stream Bytes And I Send Over The Netwrok Here Is Code
MemoryStream ms = new MemoryStream(); pictureBox1.Image.Save(ms, System.Drawing.Imaging.ImageFormat.Jpeg); // we save the image in side the Memory strem byte[] pic_array = new byte[ms.Length]; ms.Position = 0; ms.Read(pic_array, 0, pic_array.Length); //
[Code]...
but when i want get the Data o mean Bytes from Network tream How can i save in memory stream then dispaly in the picture box ? i try some thing but it is gave me error !
Socket handlerSocket = (Socket)alSockets[alSockets.Count - 1]; NetworkStream networkStream = new NetworkStream(handlerSocket); int thisRead = 0; int blockSize = 1024;
I've been working on making a sprite generator and this is one thing that has kept giving me difficulties. No matter what I've looked up nothing directly says how to nor can I find anything on a similar topic to try and apply to it either. I know how to add the resources and names for the options but how do I get the options to make my picturebox image change in relation to the selection?
I've been looking for a C# library that is well documented and can show DICOM (medical CT scan data, including the image) as jpeg/bmp data that is viewable in a PictureBox.
I've only found OpenDicom which is more or less unsupported now and EvilDicom - whose owner has made some significant changes to it, making all existing stack overflow questions on it irrelevant.
I am creating an employee details project, the image is getting stored in the database but i am not able display it in the picture box.
private void button1_Click(object sender, EventArgs e) { SqlConnection con = new SqlConnection(Connectionstring); con.Open(); SqlCommand cmd = new SqlCommand("select photo from emprecordtable where eid='"+comboBox1.Text+"'", con); //SqlDataAdapter da = new SqlDataAdapter(cmd); //DataSet ds = new DataSet();
[code] ....
In sql server i have table called emprecordtable and i have the fields eid, rfid, empname, designation, phno, addres, and photo which is the image field and i have given the datatype as image but in the database the image is getting stored as Binary Data.. So, how to display in the picturebox from the database.
I am trying to build a WinForm application that will allow you to load an image into a picturebox and then draw multiple rectangles (empty or translucent) to kind of highlight areas. I want all the rectangles to stay on the image (i can take care of a clear method later). The code below has the latest two attempts I've tried. One is all commented out and the other is not. Both will load the image just fine but neither will allow me to draw/select rectangles on the image.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.Drawing.Drawing2D; using System.Linq;
What i'm trying to do is load an image from my database create some graphics to it. probably just some lines and marks and save it back to my database. here's so far what I got.
for creating graphics: } private void pictureBox3_MouseDown(object sender, MouseEventArgs e) { draw = true; } private void pictureBox3_MouseMove(object sender, MouseEventArgs e) { if (draw) { Graphics g = Graphics.FromImage(pictureBox3.Image);
[Code] ....
but the saving part doesnt work :( I think it only saves the image loaded to the picturebox but not the graphics created to it. how to merge it? i've tried to google it and found some sort of same cases but fails to make it work, something like converting it to bitmap.
I have a form with a picturebox and some buttons to move the picturebox. I don't want the user to guide the picturebox out of the form even by dragging the form border picturebox moves just in the form border, and also there is a button to guide the picturebox to the start position (start choose by user). What can i do?
Program background: Ticket Sales Details You will sell tickets in advance and at the door. Prices for buying in advance and at the door will be given. Also, the total number of tickets sold in advance will be given. Each guest will have a unique number. If there are n tickets sold in advance, then these guests will be numbered 0 through n-1. As the event starts, requests to buy tickets at the door may be made and these guests will be numbered sequentially, starting at the lowest unassigned number. The maximum number of guests will be 1000. The first line of the file contains the following three values, separated by spaces: Cost of the presales tickets (in dollars), Cost of the tickets at the door (in dollars), and the number of presale tickets. The first two values will be positive real numbers to two decimal places and the last will be a positive integer.
The second line of the file will contain one positive integer representing the number of auction items followed by a positive real value to two decimal places (at most) representing the minimum bid increment, in dollars. The first value is guaranteed to be 1000 or less and the second will be in between 1 and 50, inclusive.
The third line of the file will contain all the prices of the auction items, in dollars, separated by spaces, in order. Thus, the first price is the price of item 0, the next price is the price of item 1, and so on. These values will be real numbers represented to up to 2 decimal places.
The fourth line of the file will contain the three following positive integers pertaining to the raffle: the number of raffle tickets available, the cost of a raffle ticket in dollars, and the number of raffle prizes. (It's strange to have raffle tickets that don't cost a whole number of dollars.)
The fifth line of the file will contain each of the values of the raffle items, in dollars, separated by spaces, in order. Thus, the first price is the price if item 0, the next price is the price of item 1, and so on. These values will be real numbers with upto 2 decimal places.
The sixth line of the file will contain ten positive integers representing the number of each of the drinks 0 through 9, in order, that are in stock.
The seventh line of the file will contain ten positive real numbers with upto 2 decimal places representing the price of each of the drinks 0 through 9, in order.
The eighth line of the file will contain a single positive integer, numEvents, representing the number of events that occur at the charity ball. These events are split into two groups: actions by guests at the ball and awards given (raffle, auction, person, totalrevenue). All of the actions precede all of the awards. You will produce exactly one line of output for each event described. Here are the formats of each event that could occur:
If a patron buys a ticket at the door, a command will be on a line by itself:
BUY TICKET k
where k is a positive integer indicating the number of tickets bought at the door. These guests will be numbered as previously mentioned. You are guaranteed that the total number of tickets bought, including presales, will not exceed 1000. This is what I have so far and I cannot figure out why it wont calculate the total revenue. I am not completely sure if it is even accessing the if statement in main.
Code:
#include <stdio.h> #include <stdlib.h> #include <string.h> #define N 1000
I wrote the below code to find the line with "abc" as my parameter to strTosearch. I expected to the line 1st line but, this function always match the 2nd line. What am I missing here?
I wanted "found" to be "abc def hgi SSS".
Code in main() String found=GetstringColSamLine("mytext.txt", "abc");
I just got assigned a project in my C programming class. The objective is to find the min and max number out of a .txt file full of numbers on separate lines called "data.txt". I am pretty much stuck at this point. I don't know how to actually scan the file and print the min and max. Also, the list of numbers in the data.txt file contains hundred on hundreds of numbers. So I couldn't specify the exact amount of numbers listed in the file. I must also find the count number, sum, and the average of the given data, So far I have:
Code:
#include<stdio.h> int main() { int counter=0; int maximum=0, minimum=1; int num_data_points, avg; double max, min; FILE *sensor; sensor = fopen("data.txt", "r");
when I try to run the program (new to VC++, I click the green arrow next to "Debug" in the toolbar, right) and I get a message box - code builds without errors - but the debugger says: "Unable to start program 'c:users/sal/documents/visual studio 2010/Projects/SFML App/Debug/SFML App.exe Cannot find file specified"...well, I go to the directory it says, and nothing is even in the Debug file.
I'm trying to write a program for a pong game using a tutorial online. Every time i try to run my program its telling me "Cannot find or open pdb file" I have tried running Microsoft visual c++ as administrator and checking the box next to the Microsoft symbol server. I only get a black console screen with a blinking cursor.
I can't debug anything and get an error whenever I try. Being able to release a program to run it works sometimes, but it's hit or miss. I've created a very simple program to show the problem. The error on the screen is a result of me trying to debug, but I actually received the same error when trying to release as well.
'test.exe': Loaded 'C:UsersPcDocumentsVisual Studio 2010Projects estDebug est.exe', Symbols loaded. 'test.exe': Loaded 'C:WindowsSysWOW64 tdll.dll', Symbols loaded (source information stripped). 'test.exe': Loaded 'C:WindowsSysWOW64kernel32.dll', Symbols loaded (source information stripped).

I have write a program to read ppm file and write a new ppm file. However, I'm not sure how to find the darkest point in this ppm file.
Note: 1. there are 610200 RGB point, but my new file only created 176196 RGB point. 2. RGB range: 0-255. (0,0,0)= black; (255,255,255)= white 3. When reporting the location of your dark pixels, assume the upper left corner of the image is location 1, 1
I'm working on a silent auction program that will scan a file and find the highest from each group of bids, then have a running total of money made throughout the auction. I'm pretty sure the rest of my code works, i'm just getting stuck on finding the largest number from the line in the file, saving it, then moving to the next auction.
input file text (first number is num of auctions, after that it's num of bids, then the bids):
Sample Output Auction 1 sold for $500.00! Auction 2 sold for $700.00! Auction 3 sold for $300.00! Auction 4 sold for $920.00! Auction 5 sold for $50.00!
The silent auction raised $2470.00 for charity!

The first loop will print out all of numbers in the velocity column. The second while loop is looking for the maximum value in that column. It is supposed to print out the max velocity in the end of the second loop. However, when I build and run the program, it's crashed. I run debugger and received "Segmentation fault" error. When I eliminate the second loop, it run just fine I use Code::Block for text editor.
I have a program that gives the user the option to create an employee ID, name, address and so on. It also has the option to search employee by employee ID.
What I want to know is how to add and replace employee info. For example employee changes address. Also how to delete employee information from text file.
Here's my code:
//This program uses file input and output for an employee information system. #include <iostream> #include <string> #include <fstream> using namespace std; int main(){ ifstream inFile; //declare ifstream as inFile and ofstream as outFile ofstream outFile;
How does one read the number of characters in a .txt file excluding the spaces? Here is my code so far. I am getting 67, which is the correct number including spaces but can't find out how to exclude them. Here's my code!
#include <iostream> #include <string> #include <fstream> using namespace std; /////////------------------///////// //Function Prototypes// int fileLength();
I've written a function that has to receive a word as parameter, and then has to find the amount of times that word (uppercase & lowercase) occurs in a text file:
For example, if the word "the" is sent as a parameter, the total amount of times the words "the" and "THE" occurs in the text file, has to be calculated.
However, my function is not displaying the correct amount, what is wrong with my function:
int WordCount :: countWords(string wrd) { int counter=0; string temp = "";
