There really isn't anything we can do to help here: there are just too many variables.

So start by looking for differences between the PC where it works - your development PC - and teh PC where it doesn't. Look at the OS, the size (32 bit / 64 bit), the .NET versions installed, the datafiles your app uses, databases, the disk space, anything which is different. If you can't find anything there that looks significant, then start by adding logging info to your app and work out how far it gets before it crashes.
Then, narrow the area down with more logging, and start using try...catch blocks to try and find out what the exception (if any) is.

There isn't anything we can do from this end: you need to gather information and start thinking about your code - which we can't do because we have no access to it!

There is a good change you didn't deploy one or more .DLL's those referenced .DLL's depends on. With the information you provided there isn't enough information to tell which .DLL(s) are missing dependencies, if any.

I suggest you go down the list of the assemblies you references and get the documentation on each library to see if you have to do something special on the client machine to deploy that library.

Start by using the debugger and looking at the data you have downloaded from the file: what exactly does it contain?
Then look at the array content post-split: what is in the second array element, exactly?

The chances are that the data is not what you expect, and the "second line" does not contain just a number.
But we can't check that for you!

I saw the file, and i suppose you get these 2 strings:
"15.66"
"15.88"
Those strings hold double value, and you get exception because of that.

Hide a Panel on MDI Container

Hi,

I have frmMain which is an MDI Container and (frmCustomer & frmOrders) which are MDI child

On frmMain I have panelHeader.

I want to hide panelHeader every time frmCustomer or frmOrders are shown and then show it back when MDI child is closed.

so what I want is if an MDI child is shown (MDI Child > 0) then panelHeader visibility to be false else it should be true.

How can I dot this please?

Thanks,
Jassim[^]

Toggle the Visibility-property in the appropriate event.

That might mean having a window-focus event recounting how much of those windows are approrpriate (OfType<frmcustomer> and..) and update the status.

What have you tried?

Ive create a method that will handle keydown event

it has a lot of "if" statment and it say i has a high complexity and its scores 33

is there way to decrease its complexity
actually the method is not finish

here is the code

private static void FlyouCommandEvent(object sender, KeyEventArgs e)
{
    var fd = (FlyoutDialog)sender;
    if ((e.KeyCode == Keys.A || (e.Alt && e.KeyCode == Keys.A)) && fd.CanExecuteCommand(Helpers.FlyoutCommandAbort))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandAbort);
    }
    else if (e.KeyCode == Keys.Escape && fd.CanExecuteCommand(Helpers.FlyoutCommandCancel))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandCancel);
    }
    else if ((e.KeyCode == Keys.I || (e.Alt && e.KeyCode == Keys.I)) && fd.CanExecuteCommand(Helpers.FlyoutCommandIgnore))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandIgnore);
    }
    else if ((e.KeyCode == Keys.N || (e.Alt && e.KeyCode == Keys.N)) && fd.CanExecuteCommand(Helpers.FlyoutCommandNo))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandNo);
    }
    else if ((e.KeyCode == Keys.N || (e.Alt && e.KeyCode == Keys.N)) && fd.CanExecuteCommand(Helpers.FlyoutCommandNone))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandNone);
    }
    else if (e.KeyCode == Keys.Enter && fd.CanExecuteCommand(Helpers.FlyoutCommandOK))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandOK);
    }
    else if ((e.KeyCode == Keys.R || (e.Alt && e.KeyCode == Keys.R)) && fd.CanExecuteCommand(Helpers.FlyoutCommandRetry))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandRetry);
    }
    else if ((e.KeyCode == Keys.Y || (e.Alt && e.KeyCode == Keys.Y)) && fd.CanExecuteCommand(Helpers.FlyoutCommandYes))
    {
        fd.ExecuteCommand(Helpers.FlyoutCommandYes);
    }
}

any suggestion is highly appreciated

There's a heck of a lot of code going on here, and it certainly appears as though you're violating SRP here. Rather than doing things like this, I would look to implement separate classes that do what you need to do - each class would then decide whether it was the one that handled the case. There's even a name for this, as a pattern; it's called the Chain Of Responsibility. So, you would end up with something like this:

public abstract class HandlerBase
{
  private IHandler successor;
  public void SetSuccessor(IHandler successor)
  {
    this.successor = handler;
  }
  public virtual void HandleRequest(KeyEventArgs e)
  {
    if (CanHandleRequest(e))
    {
      return;
    }
    if (successor != null)
    {
      successor.HandleRequest(e);
    }
  }

  public abstract bool CanHandleRequest(KeyEventArgs e);
  public abstract void HandleRequest(FlyoutDialog fd);
}

public class FlyoutAbort : HandlerBase
{
  public virtual bool CanHandleRequest(KeyEventArgs e)
  {
    return (e.KeyCode == Keys.A || (e.Alt && e.KeyCode == Keys.A)) && fd.CanExecuteCommand(Helpers.FlyoutCommandAbort);
  }

  public abstract void HandleRequest(FlyoutDialog fd)
  {
    fd.ExecuteCommand(Helpers.FlyoutCommandAbort); // In reality, I would look to move the command from Helpers, into this class.
  }
}

public class FlyoutCancel : HandlerBase
{
  public virtual bool CanHandleRequest(KeyEventArgs e)
  {
    return e.KeyCode == Keys.Escape && fd.CanExecuteCommand(Helpers.FlyoutCommandCancel;
  }

  public abstract void HandleRequest(FlyoutDialog fd)
  {
    fd.ExecuteCommand(Helpers.FlyoutCommandCancel);
  }
}

Then, in your main class, you simply do this:

private FlyoutAbort flyoutAbort;
private FlyoutCancel flyoutCancel;

private void InitializeChain()
{
  flyoutAbort = new FlyoutAbort();
  flyoutCancel = new FlyoutCancel();
  flyoutAbort.SetSuccessor(flyoutCancel);
}

Finally, all you need to do to handle the request (if it can be handled that is), is call:

flyoutAbort.HandleRequest(e);

Off topic with regards to your question but is your key testing code correct?

I assume the intention of the following code is to allow A or Alt-A

if ((e.KeyCode == Keys.A || (e.Alt && e.KeyCode == Keys.A))

The first condition does not test for modifier keys so would be true for A with any combination of modifiers keys (including none). Due to shortcut evaluation the second condition will be evaluated only if the first is false, that is if the Key is NOT A and I'm sure you can see the problem with that. Even if it was evaluated the condition does not exclude additional modifiers so Ctrl-Alt-A would be allowed.

The solution is to test the key and the modifiers separately. Specifically the modifiers test should be for none or just Alt.

if ((e.KeyCode == Keys.A) && (e.Modifiers == Keys.None || e.Modifiers == Keys.Alt))

Hope that helps, Alan.

I really hate using anonymous types because they just make your code harder to debug and understand. I strongly suggest replacing the anonymous type with an actual class. I see no reason why you need to use a anonymous type here.

Anonymous types are good for use inside the method where it's defined, not really for passing around to other methods.

The reason being is that you have to define your anonymous type all over again just so you can cast the value back to that type. That's doubling your work and introducing another opportunity to introduce bugs into your code. This is especially true in this case because if you change the type definition, you have to do it in multiple places. YUK!

Whilst I agree you should really use a concrete class for anything that leaves the context in which it was created, to answer the question you could use this

private void myWorker_DoWork(object sender, DoWorkEventArgs e)
{
    dynamic arg = (dynamic) e.Argument;
    Console.WriteLine(arg.DateRangeStart);
}
