I'm trying to print numbers in a label but I'm not having success. For example, I have the following code:
private: System::Void txtLeftWheel_Click_1(System::Object^ sender, System::EventArgs^ e)
{
for (int i = 1; i <= 1000; i++)
{
Sleep(100);
this->lblLeftWheel->Text = (Int32::Parse(this->lblLeftWheel->Text) + i).ToString();
}
}
The idea is that when I click the button, the numbers on the label increment from 1 to 1000.
The Sleep() is there to slow down the loop and the user can see something happening. However, if I put the Sleep() before the label->, the form freezes completely. If I put the Sleep() after the label-> text, the form freezes for a few seconds and the label text goes from 1 and jumps straight to 1000.
The expected functionality is that the label displays numbers 1 through 1000 but increment every second.
My goal is to have couple of items in the listbox and when highlighting one item a image in the picturebox should appear, and so on for each item in the listbox.I just don't know how to change image depending on selected item in the listbox instantly.Also when i highlight item a text in label should be like in highlighted item in listbox.
I am trying to change label text on button click, the way label.text = "string" work well before but not in this case. I tried to put this on other method and it work..it is just not working on the button that I would like to fire..
C# code :
protected void btnTotalGroupMember_Click(object sender, EventArgs e) { string s = "there"; string[] words = s.Split(' '); foreach (string word in words) { Label1.Text = s;
I am working on my first RPG. Nothing fancy so far... I haven't developed a story or anything, just trying to get the gameplay hammered out. Anyway, I have a couple of NPCs and Items and I was wondering how I should program these interactive spots. I'm unsure whether I should loop the Room info or continue forward with if statements. With Items, I want to prevent the player trying to use the option to get the item again (after you pick up the item, the option is gone. Here are a couple examples of where I have the problem
else if(playerloc == 3) { cout << "There is a hooded figure in the corner. " << "The person waves you over. ";
[Code]....
What I want to do after the character interaction is complete is continue forward with the option to go south or east. I could return to the room menu, or continue by coding forward and allow the option to go east or south with more if-else-if chains..
In the next bit, I want to program the item to be picked up and then the treasure chest will be empty.
else if(playerloc == 5) { cout << "There is a treasure chest in the Northwest corner of this room. "
I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:
OleDbConnection conn = new OleDbConnection(); conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb"; conn.Open(); Form1 frm1 = new Form1(); //frm1.Show(); //string tableName = frm1.tableName; //string time = "4/5/1991"; string fullName = memberscmb.Text;
I'm attempting to print a series of text from this loop, but for some reason all I am getting is the sum total and the number 1, like this
1 5175.11
When I want to get it for each iteration of the loop. I've cycled over this and compared it to my other loops I've used and I'm lost as to why this isn't working. I also tried using a do while but that didn't work as well.
I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm(); frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.
In my program I have WinForm and on this WinForm I have a User Control. On the User Control I have a TreeView.
So what I'm trying to do is passing a number, which is in the TreeNode Text to the WinForm. On the Winform I have a couple of Labels which I want to fill with Informations. To get those informations I have a class with a method which Needs my number from the User Controller. But I can not Access the Labels in the WinForm Method.
Here my code:
User Control private void TreeView_SelectedNode(object sender, TreeViewEventArgs e) { CwiaMain frmMain = new CwiaMain(TFS, TfsConnect); TreeNode tn = _tvWorkItemList.SelectedNode; if (tn == null) { MessageBox.Show("Error");
[URL] when I try to write my output to a file. I am building a life insurance premium calculator with c++. What my calculator does is read in a text file called "policies.txt" containing a number of different policies. For example:
Pol1 M N 20 100000 1 .04 99 Pol2 F S 30 100000 1 .05 99 Pol3 M S 72 750000 1 .03 99 Pol4 F N 45 1000000 1 .05 99
And using this, it creates a single premium. Once the calculator calculates the premium of each policy, I want it to write out the premium amount of each policy to a textfile called "output.txt". The problem is that when I check my "output.txt" file, only the premium for the last policy shows up. It only reads:
Premium for Pol4 is 220384 When I want it to read:
Premium for Pol1 is 14101.6 Premium for Pol2 is 14221.2 Premium for Pol3 is 582391 Premium for Pol4 is 220384
How come only the last policy is showing up? and is there any way to make all four policies appear in my output text file? Here is my code:
My program involves trajectory planning using cubic spline method for a robotic arm. In the process, I had to calculate joint angles for each point in the path. In the last few lines of the code I need to write the values for counter and theta1 into a text file which I called "Test.txt". I am doing this using a nested for loop(the counter runs until it reaches 19 and hence need 19 theta1 values corresponding to it). However, I can't get all the theta1 values transferred to the text file.The statement within my inner loop is wrong and don't know how to fix it.
I am facing a problem that I want to write the label name in a word document and the word is connected with the visual studio using COM option. Like if the name of the is Label1 and I want to write it in a word document using some code or something else.
With the LoadLibrary function (followed by GetProcAddress) you can get a function or any other thing that is on DLL export. AFAIK, when you assemble one program, it loses all user-reading data (names in general). How do the OS's get them?
My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.
I have a dbcontext object from a table that I'm trying to assign to a label, but the page is blank and the label doesn't show the output. How can I successfully assign a label on button click so that the table data is visible? The object I'm referring to is aMessage.highScoreEasy
protected void myScoresButton_Click(object sender, EventArgs e) { int num = 2; int num1 = 5; int num2 = 6; easyScoreLabel.Text = num.ToString(); mediumScoreLabel.Text = num1.ToString();
This program was running at first but when I started to change the couts and cins to fouts and fins (in order for them to be save in a file directory), it shows a lot of errors such as:
initialization of 'fin' is skipped by 'case' label 'std::ifstream fin': redefinition
Here is the code of the program:
#include <iostream> #include <iomanip> #include <fstream> using namespace std; struct file{ int fnum; char fname[50], lname[50];
Write an interactive text based menu interface (using a loop) that will allow the user to
Enter a task or assignment Display all of the tasks that are in the file Find a task by Course Quit For each task, you need to keep track of:
Course Name that it is for (e.g., CS162) Description of the assignment (e.g., Finish Lab 2) Due date (e.g., 9/26/2009)
Allow the program to keep looping until user wants to quit. When the program starts, it should load the tasks from external file ("tasks.txt") into memory. When user enters the three items of a task, the program needs to read them in, save them in memory and eventually write them to the external data file ("tasks.txt"). The file format could look like: (The ';' is used as a delimiter or field seperator.)
Some Implementation Requirements:
Write at least four functions WITH arguments for this assignment. Use struct named Task to model task Use array of structs to model the collection of tasks. Hint: In this assignment, the description and course name may have multiple words in it. Therefore, you now SHOULD read using the 3 argument version of get. Watch out. When using the 3 argument version of get you need to make sure to remove the delimiter or newline. Therefore, anytime you read (even a confirmation message), make sure to eat the newline! Make sure to have a delimiter written between each item in the file – like a newline. This will be important when you read the information back from the file.
This is my code so far:
#include <iostream> int main() { char cname[25],desc[20];
Ok here I have a program that reads a word from a text file randomly and matches it with the definition. The user has to guess what the word is according to the definition.
I'm having trouble with my for loop, I'm not getting any errors. But I just know something is off.
using namespace std; int main(){ int number; int count = 0; int numOfGuess = 0;

I am a newbie to C++ and VS ++. I have created a windows form application by dragging and dropping button, label..etc. i wish label text to be appeared as return value from a function. The function returns ' const char* '.how this returned string pointer can be used to display label text.?
I have a non form class. I want to update label/ check status of check box etc.. in non form class ( here resides functions that contains logic). How can i do that ?
We are making a program--but every time we input a value for scanf, the following for loop does not work and the program quits without displaying the for loop's function. We are not getting any errors.
I have tried to submit this topic before but i didn't submit my whole code and it was removed. So here it is. All I am trying to do is load form2 from form1 then back to form1 from form2 for a certain number of times the get out of the loop. I am new to C-Sharp and it seems as though I cant seem to figure out a way to do this.
Here is form1 and form2 code. I have commented out a few things I have tried.
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data;
