This for loop replaces the stars ******** in an array that contains a word to be guessed with the correct letter (c) that the user inputs if the word contains that letter.
Problem: After every guess the same hidden string of stars ******* is displayed instead of ex: ***W**** (assuming W was entered by the user)
How can I update the old ******** string in the Stars array with the new string that includes the correct letters chosen, so after every correct guess at a letter in the word a new string is displayed including the correct letters chosen?
I'm pretty sure I have to use strcpy but not sure how to implement it using a loop.
Code:
for(i = 0; i < strlen(unscrambledWord); i++) {
if(unscrambledWord [i] == c) {
Stars[i] = c;
} }
I want to do this but do not know exactly how to do it:
Create an array of space ship objects and write a program that continually updates their positions until they all go off the screen. Assume that the size of the screen is 1024 pixels by 768 pixels.
I have begun to write a bit code but the problem is when you want to see the space ship moving step for step on the screen I do not know how to create the ship visible so you can see it is moving. Here's my code so far
Code:
#include <iostream>
using namespace std;
struct SpaceShips
{
int x_coordinate;
int y_coordinate;

is there a way to tell WPF that I'm going to do a lengthy update on a control (TextBlock), and that it shouldn't redraw it until I tell it I'm done? I'm adding a large number of items to the Inlines property, and it has to redraw the entire control every time I add an item, which takes a very long time - about 1 second for every 100 items. I know some other frameworks allow freezing of certain controls, but I haven't been able to find anything in the documentation or on google. I've tried collapsing the TextBlock, and then making it visible again after the update, but it did not improve the performance at all.

Am trying to update the MSI database via a transforms (MST) file. using below code.
WindowsInstaller.Installer inst = (WindowsInstaller.Installer)new Installer();
Database instDb = inst.OpenDatabase(MSIFile.FullName, WindowsInstaller.MsiOpenDatabaseMode.msiOpenDatabaseModeReadOnly);
instDb.ApplyTransform(MSTpath, MsiTransformError.msiTransformErrorViewTransform);
WindowsInstaller.View view1 = instDb.OpenView("INSERT INTO `Registry`(`Registry`,`Root`,`Key`,`Name`,`Value`,`Component_`) VALUES('" + Registry1 + "', '" + Root + "', '" + Key + "', '" + Name1 + "', '" + Value1 + "', '" + Component + "')");
view1.Execute(null);
view1.Close();
instDb.Commit();
When i try for MSI database before including instDb.ApplyTransform(MSTpath, MsiTransformError.msiTransformErrorViewTransform);
it worked fine for MSI, the values got updated in the MSI database, But i face error in the above line of code.
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.

View 3 Replies View RelatedIm trying to make a Tic Tac Toe board for an assignment. Right now it compiles fine but when I enter an x or o it does not update the board it just prints out the '.'s that the board is initialized to. Also, when I get to player 2 the board will printout twice so its 6 rows or 3 columns. The project uses a main to ask who starts then goes to a play function that asks for inputs and calls the makeMove function to place the x's and o's and the print function to display the updated board.
bool Board::makeMove(int rowIn, int columnIn, char currentPlayer) {
if (playBoard[rowIn][columnIn] == '.') {
playBoard[rowIn][columnIn] = currentPlayer;

ProductID|Name|Category|Description|quantity
1|Coat|men|black coat|5

3|Pillow|Home|white|10
a user can edit quantity ie productID 1 has quantity 10, and ProductID 2 has quantity 3, it should update once clicked update button. however i must highlight both rows to do it so if i leave the selected cell on product id 3 it will upate only that row. is there a way to update the rows that have been changed when not highlighted.
for (int i = 0; i < dataGridView1.SelectedCells.Count; i++) {
int selectedrowindex = dataGridView1.SelectedCells[i].RowIndex;

I am trying to create an application interface serial data reception using c #. I send the data from the serial adc microcontroller adc atmega 16 ... the data is 0 to 1023. In the textbox that I use as a data reception, data updates to the bottom if I use ReadLine coding.
examples:
1023
1023
1023
256
669
If I use ReadExisting, the data displayed by the textbox moves to the side. examples 102310231023256669
When the data changes from 0-1023 of serial communication, and clear the data will store in otomatiis in the textbox.
When there is reception of data with a value of 1023 and immediately there is a change to the value of 555 textbox value will not store the value of 1023, I want the value in 1023 immediately deleted automatically and change the value to 555 when a change in the value of the data ...

It's my understanding that there are three ways to go about updating a control on a form from a class.
A) Instance the form, eg: Form1 Frm = new Form1();
The problems I have run into with this is that while writing text to a richtextbox using the instance Frm, the richtextbox never updates on the form.
B) Passing the object to the class.
This method seems less used and can be very problematic. Haven't looked into it thoroughly.
C) Exposing the objects using classes within the Form.
While making methods public they still do now show as available for use when calling from classes, unless I instance them but then I run into problem A. I've considered making the methods static so no instancing is required but when doing so the object(in this case richtextbox) becomes invalid due to itself being instanced by the automatically generated code when adding the object.
I know there is another way to pass values then force the object to update but that won't necessarily work with a richtextbox as you have the option to deal with color and font variations.
I imagine I'm missing something pretty simple here but I can't find any resources online about how to handle objects with more complex data than just straight text.
Example of problem A
//called from a class
Form1 Chat = new Form1();
Chat.BeginChat();
Chat.AddChat(Color.Lime, "Testing");
Chat.EndChat();
