Hi,
in an application i used a trackbar to set input values to an output channel.
The arrow keys left right works fine, the arrow keys left decrement right increment the value.
But the arrow key up decrement and the arrow key down increment the value ??
with the key page up also decrements and the key down increments the value too ?
How could i fix this problem , so that arrow key up increments and arrow keys down decrements,
also the page up down ?

It's only a bug if you attribute "Up" to increasing the value and "Down" to decreasing it. If you turn the TrackBar vertical, the keys are correct. Visually, it's a bit backwards to reverse the keys.
You can create you're own TrackBar class by inheriting from TrackBar, then override the OnKeyDown method. Check for the appropriate keys and handle the Value of the trackbar yourself, skipping sending the keys to the base OnKeyDown method.

Hi, thanks for the answer,
i've created my own class, but if the code is running, nothing happens, because
if i press arrow up or down, this.value will correct set, but the control self set's
the value too (so he made the opposite and the control value is allways the same ) !!
Why ? i didnt call the base.OnKeyDown.
public class myTrackbar : TrackBar
{
protected override void OnKeyDown(KeyEventArgs e)
{
if(e.KeyCode == Keys.Up)
{
int delta = this.SmallChange;
this.Value += delta;
}
else if (e.KeyCode == Keys.Down)
{
int delta = this.SmallChange;
this.Value -= delta;
}
}
}

Hi,
I am trying to build a Network Printer Monitor. I found few softwares available for the same.
I need a print monitor component like dll or user control so that I can use it my application.
Or is there any development kit/API available for it?
Any suggestion?
Thanks,

Rather than re-invent the wheel, try the printer manufacturer?

What is that you want to do ? Can you explain it clearly?

Walk up to it and rest your head against it??
Seriously, how is anyone supposed to answer that question?
What is it you're trying to do by "listening to a network printer"???

Hello,
I want to search a set of directories that are organized by "LastName FirstName". However, the number of spaces between each name might vary (most only have 1 space, but some have 2 or 3 b/c of a typo). The only search pattern I know of to accommodate this is "LastName*FirstName", but I'd rather use some regex like "LastName[ ]+FirstName", that only allows spaces between the names. Is this possible, or would I just have to get all directories and manually evaluate the regex on each one?
Thanks,
Dybs

You have to get the list of files and RegEx each one yourself to find the matches. The search options in the GetFiles methods, or whatever else you use, do not support RegEx expressions and there is no search option that will only match "any number of spaces".

Dave,
I thought as much, but wanted to confirm. Thanks.

You'd wish the 'search pattern' worked like a wildcard, but it doesn't. Well, maybe just barely in that it's limited to the wildcards '*' and '?'. I got what I needed using LINQ and regular expressions:
DirectoryInfo[] jobs =
_dirJobsFolder.GetDirectories();
if (jobs.Length == 0) return null;
Regex r = new Regex("\d\d\d\d"); // Four digits
var joblist = from job in jobs
where r.IsMatch(job.ToString())
orderby job.ToString() ascending
select job.ToString();
_Jobs = (string[])joblist.ToArray();

I have a third party api that seems only to work in a winform, not within a windows service or console program. From the look of the api it seems to be message based.
Is it possible to somehow make a c# winform invisible. Or, how can I add a message queue to my c# windows service to see if that is what is needed?
