Hi everyone,

I just recently started programming in C# (my first language, also) and I'm still pretty green.

I was wondering how, or if it's possible, to initiate a process in a parent form when a boolean variable in it's child form is set to "true".

I see events such as "text changed" but I need something in the parent that can catch a variable change on the child as soon as it occurs and take action right away. Any suggestions?

Thanks! Smile | :)

you could try creating your own events in the child class and handling them in the parent class.

look here for good example:

I dont think you can take another approach. If you want to do something, when another form changes you need to listen for that change.

I dont know what your exact requirements are but perhaps you could use static functions in another class. Or just call the function by accessing the child forms parent form.

something like (though i have not tested):

FormOfTypeParent parentForm = (FormOfTypeParent)this.ParentForm;
parentForm.MyFunction();

FormOfTypeParent = the form type that is your parent form i.e. MainForm, Form1 etc.

calling this when a variable changes, make the variable a property i.e.

private bool changingThing = false;

public bool ChangingThing{
get{return changingThing;}
set{changingThing = value;ProcessChange();}
}

private void ProcessChange()
{
if(changingThing)
{
FormOfTypeParent parentForm = (FormOfTypeParent)this.ParentForm;
parentForm.MyFunction();
}
}

I am attempting to find another way to get around this problem, so I have another question regarding this:

Is it possible to call an event in a child form from the parent form?
I've attempted this in the past without success, but I feel that it should be possible given that events that don't involve "physical" (such as a button click event) components on the form can be called by the parent.

Can anyone verify this and/or explain why/how it is or is not possible? Thanks so much!

By adding them? With a loop? However you want?

Form1.Controls.Add(controlName);?

Don't really understand your question. You create them at run time.

Hi,

when you add a Control to myForm using Visual Designer, what it does is two things:
1. add code to a file (probably myForm.designer.cs);
2. execute that code, so you see the results immediately.

Have a look at that code, copy it, paste it elsewhere and adapt it according to your needs, and it will do similar things at run-time.

You have a Panel class. Create its object and add it to form's controls whenever you want to.

The word "politics" describes the process so well: "Poli" in Latin meaning "many" and "tics" meaning "bloodsucking creatures."

Hi,

does anyone know where the individual character descriptions (not the font name) are held in a .ttf file?

thanks

AFAIK the information is stored in tables which are defined in the header of the file. For the information itself, perhaps these would be interesting:

Hi all,

I am trying to terminate an application on a remote machine. Any ideas on how to do this in C#?

Many thanks in advance

Yeah, go to the remote location, use the mouse or task manager or kill whatever process you'd like. Otherwise, look into remote access.

Your intelligence isn't questioned, your common sense is.

How many times do people post questionable requests here? Hide from task manager? Keylogger? Now remote access to kill applications? Maybe you might wanna brush up on that there intelligence a bit now that I think about it..

As long as you've been a member here you should realize that this questioned is asked at least once a week. A little research would have given you the answer.

You need to have control over the remote machine and that makes it suspicious. Controlling someones else's system is always on the darker side.

That can only be done if you've got admin rights to the target machine. If not, there's nothing you can do.

Once you have the admin permissions, you can use either the Process class, or WMI and the System.Management namespace to do this. In the later case, you'd be using the WMI Win32_Process class.

Since this is a very sensitive subject, I leave the research up to you. You've been given more than everything you need to research this subject yourself.

That statement should have come very apperent to some of the other members ...

Furthermore I would like to thank you for the only positive feedback.
