Actually I'm glad, otherwise non-elevated programs could randomly jam my CD drive - but no wait, I'm on XP, so they can do it anyway Frown | :(

Sorry - that post's misleading as Luc and I went off topic a little (I'll edit again to make that clear).

Getting hard drive serial number by similar method doesn't work without elevation.
Locking the CD drive does work without elevation WTF | :WTF:

Work that out, one locks the hardware, the other reads a few bytes of insignificant data. Which one does MS decide to block Confused | :confused:

One day I'll understand their logic... maybe!

Simple progress bar code not working correctly.

Re: Simple progress bar code not working correctly.

Good morning.

I have the following code:

uipc.tsProgBar.Style = ProgressBarStyle.Marquee;
uipc.tsProgBar.MarqueeAnimationSpeed = 100;

// Do some processes

uipc.tsProgBar.Style = ProgressBarStyle.Continuous;
uipc.tsProgBar.MarqueeAnimationSpeed = 0;

If I put a messagebox after the
uipc.tsProgBar.Style = ProgressBarStyle.Marquee;
uipc.tsProgBar.MarqueeAnimationSpeed = 100; ,
then the progress bar with start "scrolling" and stop when the user click Ok on the messagebox.

Any suggestion? Thank you, WHEELS

If you're doing your processes on the main thread then the gui won't be able to update as you'll have hold of the thread. Look at using a BackgroundWorker so your gui remains responsive.

C# Winapp Window focus

Re: C# Winapp Window focus

Good morning.

We are having a challenging time when we switch back and forth to different form windows in our app.

The form gets hidden underneath the other windows and a random window on the task bar (e.g. Outlook) get the focus instead. The user has to then go ALT + Tab and select the proper window.

Does anyone know how to prevent the Form (window) from losing focus?

Thank you, WHEELS

Form_Load event problem

kanchoette27-Aug-09 4:01

27-Aug-09 4:01

Within my Form I am using

this.Load += new System.EventHandler(this.ItemForm_Load);

 private void ItemForm_Load(object sender, EventArgs e)
        {
            myDataSet.Merge(mainForm.newDataSet);           
        }

However, the merge does not take place. Placing a breakpoint in the debugger shows that the ItemForm_Load never gets hit.

Any pointers would be much appreciated.

Where are you subscribing to the Load event? If it's after it's loaded it's never going to get called again. If it's not already there, put it in the constructor.

Many thanks for your reply. I had my load subscription within

private void InitializeComponent()
{ 

}

Hi,

InitializeComponent() is the one method created and maintained by Visual Studio; you should not edit this method (and, since VS8 or VS9 it normally is in a separate file,
based on C#3.0 partial classes, so you shouldn't even edit the entire myForm.designer.cs files

Having it in there, is technically as good as having it in the Form's constructor, so the problem must be elsewhere. With the little info you have provided, I can't help you any further though.

How to limit the number of simultaneously connected clients

I'm confused, why are you manually maintaining the form load event handler. If you double click on the forms title bar VS creates this in the Designer.cs as with any other event wiring. I only ever do this if I have multiple subscribers to a single event or I'm creating a custom event.

Just stop calling accept until the number of connections is below your threshold value again?

Based on needing to control the conections per client, you are going to need to establish who the connection is from. What is the clint that is connecting? Can you not manage your interface so that after accepting the connection they must send a message to establish the full session. That way they can [provide additional information so the server knows who is connecting.
