Hi,

After you have initialized the combo box with values try using this :

[combo_box_name].SelectedItem = [value];

.
(without the brackets) Smile | :)

It works for me. Is this what you were asking?

Regards,
Alex

How do I disable external memory writing access to a Process?

Combobox.SelectedIndex = 0; is more accurate. As well as check if Combobox have items. eg

if(Combobox.Items.Count != 0)

I'm sure the title is confusing, but here's what I'm trying to do: I have a process that I create using the System.Diagnostics.Process class, and I want the memory the application uses to be read-only to all external applications except mine, that starts the process.

Does anyone know of a way to do this?

Not possible. Windows doesn't support what you want to do.

I see, well that's disappointing. I guess I'm going to have to go about this a different way then.

Thank you.

I'm not sure what you want, but isn't memory from other processes always read only unless the process using it explicitly shares it? The problem isn't other apps snooping at your 2nd processes memory, it's that unless #2 cooperates you can't snoop either.

Today's lesson is brought to you by the word "niggardly". Remember kids, don't attribute to racism what can be explained by Scandinavian language roots.

What I was hoping to do is create a process and then disallow any other process from modifying the memory allocated to the process I generate aside from the process itself, and the app that generated the process.

I don't think that process memory is protected like you say, as game trainers and the like wouldn't be nearly as abundant if the memory was write protected.

Could it be an option to spawn a remote process? I cannot snoop memory that's on a computer that I have no access to Smile | :)

Unfortunately, no, that is not an option. Although, a great idea if it was an option.

Can I determine CPU/RAM useage percent when use Thread in Windows Service?

For example I want to allow max %10 CPU usuge for this thread?

Hi,

there are no provisions for limiting a thread's CPU usage.
You could throttle it yourself by adding some Thread.Sleep() calls.
On a multi-core CPU with N cores each thread cannot take more than 1/N of the available cycles, so on a dual-core a thread's maximum would be 50% anyway.
