Start by using the debugger: put a breakpoint on the first line in the function, and run your code through the debugger. Then look at your code, and at your data and work out what should happen manually. Then single step each line checking that what you expected to happen is exactly what did. When it isn't, that's when you have a problem, and you can back-track (or run it again and look more closely) to find out why. You need to find out which argument is out of range, and what the valid range is - until you have that, you can't start looking at why it's out of range!
Sorry, but we can't do that for you - time for you to learn a new (and very, very useful) skill: debugging!

I do. When im running without border... I don't know how, but this part just skipping
private void _Load(object sender, EventArgs e)
{
_form_resize._get_initial_size();
}
So when they skip, my
var _controls = _get_all_controls(form);
Equally 0. And i get exception

public void _resize()
{
if (_arr_control_storage.Count == 0) return;

If you are trying to "seamlessly" scale a WinForm UI ... and I recommend you don't ... this is an excellent resource: [^].
Remember that most fonts have (internally) special "optical tunings" to look good at certain discrete sizes/weights.

hey trying to get my code to dispaly a times table but it just comes out in a straight line
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using TestLibary;
namespace ICA25
{
class Program
{
static void Main(string[] args)
{
string sTitle;
bool bExit = false;
sTitle = ("ICA 25 - Times table");
Console.WriteLine("{0,60}\n", sTitle);
do
{
{
int[,] iFinal;
int iNum = GetValue("Please enter the size (4-20) of the times table: ", 4, 20);
Console.Write("Here is the times table for that size: \n");
iFinal = GenerateTT(iNum);
DisplayTT(iFinal);
}
}
while ((YesNo("Would you like to do another? Y or N:") == "Y") && !bExit);
bExit = true;
}
static public int GetValue(string s, int iMin, int iMax)
{
int iNum;
Utilities.GetValue(out iNum, s, 4, 20);
return iNum;
}
static public int[,] GenerateTT(int iValue)
{
int[,] iNum = new int[iValue, iValue];
for (int iRow = 0; iRow < iNum.GetLength(0); iRow++)
{
for (int iCol = 0; iCol < iNum.GetLength(1); iCol++)
{
iNum[iRow, iCol] = (iCol) * (iRow);
}

Hi,
1.
the way you set things up, every Console.Write is followed by a Console.WriteLine, so you will never get two adjacent numbers: every number will take a new line.
2.
Writing
Console.Write( iFinal[iRow, iCol]);
{
Console.WriteLine();
}
and writing
Console.WriteLine( iFinal[iRow, iCol]);
is absolutely equivalent.
3.
you fooled yourself by using a lot of redundant brackets. The compiler doesn't mind, but you lost track of what is inside the inner for loop and what isn't.
4.
Once you fix the problem, you'll find out you're not there yet, as Write() or WriteLine() will use whatever number of positions is required to represent the number, so the table may well be badly aligned. If so, start looking at some overloads of int.ToString().

Dear CodeProject members,
Hope you can help with the second code that i'm struggling as the other one was answered.
I'm new to C# and compiled this code but I'm stuck and getting error Argument 1: cannot convert from 'System.Management.MamangementScope' to 'string' which is in bold and underlined below
my references are
using System;
using System.Linq;
using System.Management;
using System.Net;
using System.Net.NetworkInformation;
using System.Net.Sockets;
using System.Text;
private void WMI_Click(object sender, EventArgs e)
ManagementObjectSearcher objSearcher = null;
ManagementObjectCollection objCollection = null;
ManagementScope objScope = null;
ManagementQuery objQuery = null;
ConnectionOptions objOptions = null;
objOptions = new ConnectionOptions();
objOptions.Impersonation = ImpersonationLevel.Impersonate;
//options.Username = "Username";
//options.Password = "Password";
//options.Authority = "NTLMDOMAIN:DOMAIN";
objScope = new ManagementScope("\\\\Computer\\root\\cimv2:", objOptions);
objScope.Connect();
objQuery = new ObjectQuery("SELECT * FROM Win32_PnPEntity");
objSearcher = new ManagementObjectSearcher(objScope, objQuery);
objCollection = objSearcher.Get();
//objQuery = new ManagementQuery ("SELECT * FROM Win32_PnPEntity");
Thank you and much appreciate your help.

In your variable declarations, change "ManagementQuery" to "ObjectQuery". You cannot declare an instance variable as an abstract class type and then start calling methods and setting properties on it as the abstract class won't have implementations of those properties and methods.
ManagementObjectSearcher objSearcher = null;
ManagementObjectCollection objCollection = null;
ManagementScope objScope = null;
ObjectQuery objQuery = null;
ConnectionOptions objOptions = null;

Thank you to all and to Dave thank you for correcting me.
Now i'm very happy to have completed this code.
I thank all of you again for helping.
Wish you a lovely day

I spun a quick project and copy'n'pasted the OP's code into it. Sure enough, he's got the exact error message and the line in comes up on correct.
It took me an embarrassing number of minutes staring at it before I looked up the ManagementObject class and saw it was an abstract. Then it all clicked.

Hi Dave and Richard, thank you for checking my code.
Richard yes that is error I’m getting and thank you trying Dave.
I’m stuck and will have to check Microsoft links tomorrow at work like I said it is my first time and I’m stuck and don’t understand.
Dave since you tried and saw the errors would you be kind to highlight where I’m going wrong so that I can learn from please but if you think it’s better to read the links then I would do that but if I’m not mistaken I got some of the code from Microsoft to understand and I tried but without success.
Thank you and have a great evening.

He told you exactly what to do in his original reply!
Did you try it at all?

Hi All,
Is there a simple C# Dot Net API available to record AVI files for a given set of BMP images ?
Would appreciate any code samples that shows the usage of such an API !
Thanks In Advance !

What do you mean by "column header sort doesn't work"?
Please show your sort method, and explain which part of it has the problem.

I want to number the dataGgridView but it doesn't work, you see the red rectangular image file
