I've been trying to do one last thing for an app I've been developing to help me learn c# and I don't get why its not working the number wont update after one try its very annoying and help help would be appreciated thank you :)
int num = 1;
Dispatcher.Invoke(new Action(() => Connectorbutton.Content = num += 1));
Thread.Sleep(2000);
the button is writing too only goes up one number even while its looped. I imagine its not updating the text but is in the background because I've tried to update it on the mainthread and it still wont update like I need it too. LMK if you have any ideas thank you for your time!
Do like this. Your caller block your thread.

I am sending some keys and text to a website in Firefox with this code:
IntPtr calcWindow = FindWindow(null, "website - Mozilla Firefox");
if (SetForegroundWindow(calcWindow))
{
SendKeys.SendWait("{TAB}");
SendKeys.SendWait("{ENTER}");
SendKeys.SendWait("hello world");
}
Now the problem is that it is sent too many times. For example, the text "hello word" that he sends in the text box is sent about 60, 70 times. I want each key or text to be sent only once. Thank you for your help.
I made a correction to the code but I did not get any results.
After guiding the esteemed users, I realized that the problem is in the ring counter numbers, and after changing the condition and the for loop counter, I reached the appropriate result and the problem was solved.
The counter part in the for loop can increase or decrease the value of the variable. The for loop executes a block of code repeatedly.

[how to call an integer as it is changing when loop is running i want print and calculate every single time loop runs hope you understand my question
You need to change the line
total = perunit * quanitity
to
total += perunit * quantity
this will add the result to total, not override total every time.

I want a Method in C# which is going to make a break for 5 Seconds between 2 lines of codes.
Thread.sleep(5000);
isn't working because the rest of the code does also make a break. Have you got any Idea how to solve this?
falling.timespeed = 0.6f;
falling.fallingl = -50f;
// here I want a break for 5 Seconds
falling.timespeed = 1f;
falling.fallingl = -200f;
Are you familiar with the asynchronous features in modern c#?
In c# 5 and above:
async Task DoSomeWork()
{
// Do the first part of the work
await Task.Delay(5000); // Asynchronously wait for a 5 second timer to expire.
// Do the second part of the work
}
Note that, depending on the threading context that you call this method, part 2 may be executed on the same thread, or a different thread.

I'm trying to make a C# (Windows Forms) application which utilizes SQLite. Anyway, my code is this :
try
{
db.Insert("COLUMN_NAME", data);
}
catch (Exception e)
{
//MessageBox.Show(e.Message);
}
I made COLUMN_NAME unique, so it throws an SQL error, intentionally. But I don't want to see the error message in a MessageBox, so I commented out the MessageBox.Show() line, but still the error message pops up. Is it a property of try / catch ? If so, how can I prevent it ?
P.S.
I know there are better ways to do this task, but it is not important. I just want to learn how to get rid of error messages in exceptions.
Thanks for any help !
I figured the problem. The line db.Insert(); itself has a try/catch block, which shows a MessageBox.
I found the code here by the way.
Thanks again for all the help !
There is RunTime error in your line at
db.Insert("COLUMN_NAME", data);
So you need to fix this.
Try by clean and then build your code. Then run the code. Sometimes dll file is not refreshed. It will be regeneratedby clean and build your code.

Good Day Every one,
Can you help me produce a code to produce pop up window like return confirm? the thing is it should be inside a method not after a click.
if (a == "1")
{
//Page.ClientScript.RegisterStartupScript(this.GetType(), "messagebox", "<script>$(document).ready( function() { csscody.confirm('<br/><h1> Confirmation</h1><br/> We have currently existing Details for that Upload Proceed?<br/>',{onComplete: function(e){if(e){process();__doPostBack('ctl00$ContentPlaceHolder1$btnCommitSaving','');}}});return false;});</script>", false);
//ClientScript.RegisterStartupScript(typeof(string), "messagebox", "<script language='javascript'>alert('Continue Uploading?.');</script>");
// here a pop up message should appear if he press yes he will do the procedure if no the program will cancel the procedure
// the other one is just an alert with OK button not having Yes or no
}
i tried the code with // but its not working it just passes by it in debug mode.
im sorry but i have a very minimal understanding about javascripts. so please help me any reading materials for my future reference would be ideal but a code with explanation would be better Thank you so much!
**Edit
Honestly Speaking i really do not know why it is not working in debug mode it just passes in that statement without any pop up box that appears, im really sorry if i do not know about javascripts that's why im asking help to enlighten me, also to find a way around about this problem.
ClientScript.RegisterStartupScript
you should only do it on if you want to add the script on page first load and not after you postback and you can use javascript confirm
Page.ClientScript.RegisterStartupScript(this.GetType(),
"ButtonClickScript", "confirm('Please select date within the same month and year')", true);
