how are you? I need to implement an autocomplete with a search on an entity to save it in a list of objects, all this with a previous confirmation message. After saving the item, I can't select the last line of the previously entered value. Any idea? I leave the step-by-step to try in TryMudBlazor.
TryMudBlazor Link
Search for "hey" and press enter
Confirm the message box
Select the string value (it is not possible to avoid the entire selection)
I need to save the last search value so I can continue searching for a similar item

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.

I am trying to cause a database validation error when inserting into (or editing) the database to test the try/catch
C# is too smart and catches my type casting errors.
Try inserting a value that doesn't fit into a column (a string 10 characters long in a varchar(2)),
reference a foreign key that does not exist,
a null value in a column that doesn't accept nulls,
try connecting to the database with the wrong password/user combination.
Without any sql/c# code it's hard to know how you have things setup
EDIT- answer in comments:
"do you have any identity fields? try inserting a value that already exists into that column"

I have a file contains a lot of C functions' declarations.
For example,
void Add (int a, int b);
void AddWithCarry (int a, int b);
And I am requesting the user to enter the name of the function he wants to delete and then the whole line should be deleted.
I have done the following psuedo code:
Check if line.Contains(string)
If yes, delete the whole line.
If not, check the other line.
It worked fine if the user requests to delete AddWithCarry function, but if the user requests to delete the Add function, both lines will be deleted as both of them contains the Add string.
How could I overcome this problem ?
Replace your if with:
if(line.Replace(" ", string.Empty).Contains(string + "("))
Not the prettiest way, but should work, as long as function calls are in format of : funcName();

I made a change password page using asp. When a user log in, he/she has an option to change a password by inserting a. old password in a text box, b.Inserting new password, c. Reinsert the new password. I created codes in the button OK for insert and I also made a selection using SQL string.Format. Every time I run the application, it works but no Updates been commence into my table??
If this is not a typo then you have your variables the wrong way round.
string sql = String.Format("Update Registration set
Password ='{0}'where Username='{1}'", username, newpassword);
