I have a program which I try to clock, or profile. When I compile with -O flags some functions disappears from the out put from gprof. Is there an explanation to this..?
the problem with my code is that trace toggle can only be turn on, not off and trace does not demarcate the (substring) in progress. how do i fix this?
Am developing windows forms application where in my form am fetching data into list from some object which takes around 2 minutes to complete processing so meantime i want to show progress bar before starting process till it ends with percentage. I have return a code to do multitasking but it is throwing error as "Cross-thread operation not valid: Control 'listOrg' accessed from a thread other than the thread it was created on".
private void btnOrg_Click(object sender, EventArgs e) { try { // To report progress from the background worker we need to set this property backgroundWorker1.WorkerReportsProgress = true;
I am running a windows forms project. on the form there is a datagridview, a progress bar, a textbox and two 2 buttons.
The two buttons are used to navigate through the records(one for next record and the other for previous record) the textbox displays the record that is being currently viewed.
How can I link the progress with the database or in this case the datagridview and when the next button is pressed it increments and when the previous button is clicked it decrements and also the progress to be fully filled when the last record is reached ?
For a project I'm working on, I need to be able to download a file from an FTP server and store it to a predetermined location with a predetermined name. No user interaction should be needed. Because the file is rather large, and I need the main program to remain responsive, this is going to need a progress dialog.
I could write all this myself and use the MFC wininet wrappers (CInternetSession et al) to do the downloading, but... Explorer already has this, and IE has such a dialog also. It doesn't seem unreasonable to assume those dialogs are available via some API.
Is a "FTP download with dialog" available as a windows API, or do I really need to write all this myself ?
Write a program that asks the user to enter the number of calories and fat grams in a food item. The program should display the percentage of the calories that come from fat. One gram of fat has 9 calories, so:
(Calories from fat) = (fat grams) * 9
The percentage of calories from fat can be calculated as:
(Calories from fat) / (total calories)
Extend as follow
1. The user first enters from a menu whether it is breakfast (B or b), lunch (L or l) or dinner (D or d). Use character and process by a switch. 2. The threshold for low calorie is different, for breakfast 10%, lunch 20%, dinner 30% (this value has to be assigned to some threshold variable in the above switch). 3. Include validation of menu choice. 4. In case any validation fails, display detailed error and exit the program by calling return 1 or return EXIT_FAILURE 5. Display the % from fat with one decimal digit.
Example 1: What you have to eat: B - breakfast L - lunch D - dinner What you have: C Error: C is not a valid menu choice
Example 2: What you have to eat: B - breakfast L - lunch D - dinner What you have: L How many calories: 600 How many grams of fat: 10 Your food has 15.0% calories from fat It is a low calories food
Process the menu in a switch, setting the threshold as either 10, 20, or 30%. The rest of the program will be the same regardless what was the menu choice.
Incremental development: first do the textbook problem without input validation, then extend with validation, then extend for the additional parts.
I'm having problems with progress bar when using a big number in set range. For numbers below 50000 it works very well but for big numbers like 100.000 it doesn't work, it makes 2-3 rounds of animation
Code: int number= 50000; // 50k works well but if i put 100k it won't work (it will animate 2-3 rounds instead of complete one) progressbar1.SetRange(0, number); progressbar1.SetStep(1); for (int i = 0; i < number; ++i) { listcontrol1.InsertItem(i, _T("whatever")); progressbar1.StepIt(); }
What I need to do Is constantly read the cpu percentage and display it to a textbox, but the issue is I am using the windows form not the console so I cant use a while loop. I think my best bet is to use an event, but I am not sure how.
I'm making a quiz game in c++. I've already completed it. But now I've thought of creating a profile and saving the progress for the user so when he enters his name the game continues frm where he had saved it.
I have a module that pings the network to find available devices using threading.
the money line:
var valids = range.AsParallel().AsOrdered().Where(ip => ip.Ping()).ToList();
The problem is, I need to display a progress bar while this function runs. I have the progress bar implemented with a background worker, but it won't update while the ping module is executing. I *think* it's because I'm using the available threads for the ping module.
When the user clicks a button, I need the ping module to run while the progress bar updates, or even just set IsIndeterminite to true. What would be the best way to accomplish this?
I am using codeblocks for school and I am trying to create a program to calculate a percentage for commission and a bonus. I have tried using a decimal for percentage, int and floats with casting. Every time it I try it displays 0 or just the bonus. I even took and did a test page. My head is about to pop.
Write an algorithm that can be used to calculate the commission earned in a real estate transaction. The chart below describes the formulas used to calculate the commission.
Sales Price Commission Less than $100,000 5% of Sales Price $100,000 to $300,000 $5,000 + 10% of Sales Price over $100,000 More than $300,000 $25,000 + 15% of Sales Price over $300,000
// Commission and Bonuses. #include <iostream> #include <iomanip>
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."
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.
