I created a program what will type a text for me automatically by using SendKeys command. When I press start button the text will be typed as it should, and when I press start button the text will stop from typing. The typing is done by using an interval timer which will decide when to start typing and have a brief space between typing 2 lines.
The problem is that when I start typing and type part of the message then press stop before program can type the entire message then start typing again, the message will continue to type from where it stopped. For example I want to type the message "123456789". I start typing then program types "1234" then press stop so program wont type no more. Then when I press start again program should start typing from 1, but instead my program types "56789".
How to reset the line when I stop, then start again? I tried to make the message as a "message" variable which is reset when I press stop button but it doesn't work.
This is how I set to type every interval tick:
private void Space(object sender, EventArgs e)
{
if (cbRandomLine.Checked || tickCount < lbMessage.Items.Count)
{
var index = cbRandomLine.Checked ? randomLine : tickCount;
var item = lbMessage.Items[index].ToString();
SendKeys.Send(item.Substring(currentChar++, 1));
if (currentChar == item.Length)
{
SendKeys.Send("{enter}");
tmrSpace.Enabled = false;
currentChar = 0;
}
}
tmrSpace.Interval = random.Next(10, 100);
}
private void Delay(object sender, EventArgs e)
{
if (delayCount == 0)
{
tmrDelay.Stop();
tmrInterval.Start();
lblDelay.Text = "Typing...";
}
else lblDelay.Text = "Typing in: " + delayCount;
delayCount--;
}
// METHODS
private void WhenStarted()
{
tickCount = 0;
delayCount = 2;
lbMessage.Enabled = false;
txtMessage.Enabled = false;
if (cbDelay.Checked)
{
lblDelay.Text = "Typing...";
tmrInterval.Enabled = true;
}
else
{
lblDelay.Text = "Typing in: 3";
tmrDelay.Enabled = true;
}
cbPause.Enabled = false;
cbDelay.Enabled = false;
cbRandomLine.Enabled = false;
btnStart.Enabled = false;
btnStop.Enabled = true;
btnStop.Focus();
}
private void WhenStopped()
{
lblDelay.Text = string.Empty;
whenStart = false;
tickCount = 0;
txtMessage.Text = string.Empty;
lbMessage.Enabled = true;
txtMessage.Enabled = true;
cbPause.Enabled = true;
cbDelay.Enabled = true;
cbRandomLine.Enabled = true;
btnStart.Enabled = true;
btnStop.Enabled = false;
btnStart.Focus();
tmrDelay.Enabled = false;
tmrInterval.Enabled = false;
tmrSpace.Enabled = false;
}
private void SetInterval()
{
if (nudPlusMinus.Value == 0)
{
tmrInterval.Interval = int.Parse(nudInterval.Value.ToString());
}
else
{
tmrInterval.Interval = random.Next(int.Parse(nudInterval.Value.ToString()) - int.Parse(nudPlusMinus.Value.ToString()), int.Parse(nudInterval.Value.ToString()) + int.Parse(nudPlusMinus.Value.ToString()));
}
}
private void ListBoxContentCheck()
{
if (lbMessage.Items.Count > 0)
{
btnStart.Enabled = true;
}
else
{
btnStart.Enabled = false;
}
}
You need to reset the currentChar variable.

im trying to clear the picturebox that are created from a list in my game once it has ended, i have cleared the list but the picturebox still display i have tried using the below code in a timer that is enable upon the game ending

this would do:
foreach (var control in this.Controls)

var pb = control as PictureBox;
if (pb != null)
{
if (pb.Name != "SpaceFighter")
{
pb.Dispose();
this.Controls.Remove(pb);
}
}
}
for the listbox sorting:
using System.Collections;
ArrayList Sorting = new ArrayList();
foreach (var o in listBox1.Items)
{
Sorting.Add(o);
}
Sorting.Sort();
Sorting.Reverse();
listBox1.Items.Clear();
foreach (var o in Sorting)
{
listBox1.Items.Add(o);
}
i have a method that enabling and disabling button in here.My if-else block should do when enter a number to lbDivide the 'öde', '0' and '00' buttons should be active but only activing öde button.How do i solve this ?
öde = make payment
Kişi Sayısı = How many person?
private void Bol_Click(object sender, RoutedEventArgs e)
{
lbDivide.Text = "0";
btnBol.Opacity = 0.5;
btnBol.IsEnabled = false;
lbPayment.Visibility = Visibility.Hidden;
if (lbDivide.Text == "0")
{
btnQr.Opacity = 0.5;
btnQr.IsEnabled = false;
zero.Opacity = 0.2;
zero.IsEnabled = false;
double_zero.IsEnabled = false;
double_zero.Opacity = 0.2;
}
else
{
btnQr.Opacity = 1;
btnQr.IsEnabled = true;
zero.Opacity = 1;
double_zero.Opacity = 1;
zero.IsEnabled = true;
double_zero.IsEnabled = true;
}
I think I know where the error is.
private void Bol_Click(object sender, RoutedEventArgs e)
{
lbDivide.Text = "0"; /// in this line of code you're basically setting lbDivide.text to be 0 every time the button is clicked, so the else condition will never be met.
btnBol.Opacity = 0.5;
btnBol.IsEnabled = false; /// you're basically disabling the button after the first click.
lbPayment.Visibility = Visibility.Hidden;
if (lbDivide.Text == "0")
{
btnQr.Opacity = 0.5;
btnQr.IsEnabled = false;
zero.Opacity = 0.2;
zero.IsEnabled = false;
double_zero.IsEnabled = false;
double_zero.Opacity = 0.2;
}
else
{
btnQr.Opacity = 1;
btnQr.IsEnabled = true;
zero.Opacity = 1;
double_zero.Opacity = 1;
zero.IsEnabled = true;
double_zero.IsEnabled = true;
}
}
change if(lbDivide.Text == "0") by if(lbDivide.Text.Equals("0"))
As you can see I've created an array of images, but I'm not sure how to load each image into successive indexes.
Someone told me to do this for my game but I'm not sure how or if it will fix my problem
I've made a game where the character walks left then up then down then right and a few timers that load the animation and handle the movement but when I draw using this code
*e.Graphics.DrawImage(Properties.Resources.Corn_Cobs, 70, 70, 40, 40);*
My character gets really laggy/slow but when I don't draw the image it works smoothly and the character speeds up like normal.
Here is the code:
namespace Rice_Boy_Tester_2

Hi, I have code that reads and writes to a COM port. When the program reads from the COM port it searches for a string value and puts it in a variable. After it does this, it again listens to the COM port. I need to write to the COM port and read some new data, but I'm not seeing the value has changing to a new value.
Here is my code:
private void timer1_Tick(object sender, EventArgs e)
{
sq = "777";
if (CommunicationManager.myQ.Count != 0)
{
sq = CommunicationManager.myQ.Dequeue().ToString();
textBox1.Text = sq + textBox1.Text;
buffer = Regex.Match(textBox1.Text, #"\
((.+?)\,15,").Groups[1].Value;
}
}
private void button1_Click(object sender, EventArgs e)
{
for (int i = 0; i <= numtst; i++)
{
listView1.Items[i].BackColor = Color.White;
fl[i] = false;
}
nt = 0;
flon = false;
flag[0] = false;
comm.WriteData("AT\r\n");
wait(700);
if (buffer.lenght == 16)
{
flag[0] = true
}
if (flag[0] == true)
{
flon = true;
CommunicationManager.myQ.Clear();
break;
}
}
if (flon == true)
{
listView1.Items[nt].BackColor = Color.LightGreen;
fl[nt] = true;
}
else
{
listView1.Items[nt].BackColor = Color.Red;
if (flag[76] == true)
{
button1.Enabled = true;
button1.BackColor = Color.Red;
button1.Text = "Test ERROR";
return;
}
}
comm.WriteData("ATT\r\n");
wait(3700);
comm.WriteData("AT4\r\n");
nt = 1;
flon = false;
flag[1] = false;
if (buffer == text4.text)
{
flag[1] = true
}
wait(700);
if (flag[1] == true)
{
flon = true;
CommunicationManager.myQ.Clear();
break;
}
if (flag[76] == true)
{
button1.Enabled = true;
return;
}
}
if (flon == true)
{
listView1.Items[nt].BackColor = Color.LightGreen;
fl[nt] = true;
}
else
{
listView1.Items[nt].BackColor = Color.Red;
if (flag[76] == true)
{
button1.Enabled = true;
button1.BackColor = Color.Red;
button1.Text = "Test ERROR";
return;
}
}
in the second part if (buffer == text4.text) i see only first value of the buffer variable.
i checked in the terminal and all commands working good.
How can I dynamically, during method's loops still working, assign values and make them update on the form? What happens in my program is, that when launched it hangs until it finishes (finds the solution to the sudoku) and then populates the Textboxes.
Here is the main method:
bool SolveSudoku()
{
if (!FindUnassignedLocation()) return true;
for (int num = 1; num <= 9; num++)
{
if (NoConflicts(emptyRow, emptyCol, num))
{
Grid[emptyRow, emptyCol].Text = num.ToString();
Grid[emptyRow, emptyCol].BackColor = Color.White;
Grid[emptyRow, emptyCol].ForeColor = Color.Black;
if (SolveSudoku()) return true;
Grid[emptyRow, emptyCol].Text = "";
}
}
bool checkIfFirstBackTrack = true;
do {
if (checkIfFirstBackTrack)
{
backtrackCounter++;
checkIfFirstBackTrack = false;
}
if (emptyCol == 0 && emptyRow > 0)
{
emptyCol = 8;
emptyRow--;
}
else if (emptyCol > 0)
{
emptyCol--;
}
}
while(Preset[emptyRow, emptyCol] != "");
return false;
}
}
One option would be a background worker See more information on setting up a background worker here.:
private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)
{
BackgroundWorker worker = sender as BackgroundWorker;
for (int i = 1; i <= 10; i++)
{
if (worker.CancellationPending == true)
{
e.Cancel = true;
break;
}
else
{
//// your code here
}
}
}
