Hi
I don't think that you understood me correctly, I'll try to explain it better this time. I want to get values from my db (that I have done). There are at the most 100 values, but there can also be less, but they are all in the same formate (numbers). I want to put theese number in to at double array so I can write them out in a graph.
Thanks again!

If you want to read doubles from a DataReader like a SqlDataReader, then use SqlDataReader.GetDouble (these types of methods are declared on DataReader derivatives). If each field is a double, then continously read through your DataReader like you're doing, but then iterate over the field count and read those doubles into an array. You can either use an ArrayList or use a multi-dimensional or jagged array.

Hi wizzards and all!
In the MS-Help is allways a blue banner with title.
I'd like to have the same in my html-helpfiles. Is there an example how to do it?

Right-click and click "View Source". There's your example.
If you want to generate MS-Help like code documentation, then use NDoc[^]. We went to a lot of work to provide help files that work like MSDN (both old an new) and provide other documenters as well.

No, there is a link to some 'occult' files.
I look for a snipped, which makes the blue banner.
Thanks

Trust me - it's in there. How do you think we on the NDoc team got ours to look the same?
It's this block of HTML plus styles defined in the linked stylesheet:
<div id="nsbanner">
<div id="bannerrow1">
<TABLE CLASS="bannerparthead" CELLSPACING=0>
<TR ID="hdr">
<TD CLASS="runninghead" nowrap>.NET Framework Class Library</TD>
<TD CLASS="product" nowrap> </TD>
</TR>
</TABLE>
</div>
<div id="TitleRow">
<H1 class="dtH1"><A NAME="frlrfsystemexceptionclasstopic"></A>Exception Class</H1>
</div></div>
Use the relative path to the CSS file to see the source for that, which is easy enough. The styles to look at are #nsbanner, bannerparthead, runninghead, product, and dtH1.
<div style="width:100%;font-size:2px;margin-bottom:-10px;background-color:#FF9900;filter:progid:DXImageTransform.Microsoft.Gradient(GradientType=1,StartColorStr=#FFFF9900,EndColorStr=#FFFBEDBB);"> </div>

Hi all,
I created some drawing objects, which draws image on the screen by itself. I'm using graphics drawing method inside, for example; Graphics.Draw(), Graphics.DrawRectangle() etc.
I want to ask, is it possible to draw them with OR transparency? because sometimes, they can be overlapped.
How can I solve this problem ??
Thank you for your help....

If I don't make mistake , when you set your Pen or Brush from a Color structure , you can set it with Color.FromArgb method. You have to set its first argument. (alpha)

Thanks for reply,
I know we can get Pen / Brush with alpha setting, but Graphis.DrawImage() does not contains alpha setting.
g.DrawImage( image, location);
the main problem is when I drawing some image on screen, it can't draw as transparency. Is there a way to set the alpha of Graphics property??

I think if you first draw your image , then you can draw your other objects like rectangle with this option and use transparency. Search for GDI+ articless in this site, maybe you get better solutions there.

For Xor drawing, you want to look into Regions[^]. See the Region documentation here[^].

hello,
i have created a MDI form that contain two child forms
class ParentForm : Sytem.Windows.Forms.Form
{
........
void func()
{
this.IsMdiContains = true
ChildForm1 child1 = new ChildForm1();
child1.MdiParent = this;
child1.Show();
ChildForm2 child2 = new ChildForm2();
child2.MdiParent = this;
child2.Show();
}
my question is : i want to show both child1 and child2 and i`m using the next statement:
this.LayoutMdi(System.Windows.Forms.MdiLayout.TileHorizontal);
but the problem is that i dont want to see on the screen half from ChildForm1 and half from ChildForm2. i want to see the real size form definition of both Child forms. what should i do?
thank you
koby

You could try MdiLayout.Cascade instead and see if that layout works for you. If not, then you'll have to write your own code for laying out the child forms the way you want.

Hi,
I am trying find the services which are running on my machine on polling basis, and I am trying write this to a file before shutdown. I am trying to do this using a service, I am writing the code for file writing in the OnStop() method of the service. The problem is my service starts and stops immediately. Why this is happening??
Code Snippet:
OnStop()
{
System.IO.StreamWriter file = new System.IO.StreamWriter("d:\\test.txt");
Process [] curentProcess= Process.GetProcesses();
foreach(Process p in curentProcess)
file.WriteLine(p.ProcessName);
file.Close();
}
Regards,
Satya

Your service does not even reach OnStop(), the problem is Main() or in OnStart().
To locate the failure, check the event log. Are there any exception messages from your service?
If not, you can write a log file during OnStart(), to see where the service stops.

check the event log
Yeah, I checked the event log, it's having entries for start and stop.
When I comment the code, for file opening and writing, I find it running without any problem. How the file writing of the process names giving the problem I couldn't get.

Satya

ummm... I don't really have a solution to your problem, but I think I see a problem with your service. Basically, in order for your service to work, it has to be the first service to stopped during shutdown, else the GetProcess Method won't return those processes stopped before hand.

I think you are correct. Because the GetProcess couldn't get the Processes, file writing is also failing and the service is stopping immediately. Can we give priority (for making it first to stop)??
Regards,
Satya

I'm not too familiar with services, but you might try and see doing this
Thread th = Thread.CurrentThread;
th.Priority = ThreadPriority.Highest;
during onStart if it will help.

Whoa there Tex! Really bad idea. This will not give priority to the service to be shutdown first. As a matter of fact, you'll just end up slowing down the rest of the system doing this...
You can't give priority to any service to shutdown first. You might want to try overriding WndProc and watching for the WM_QUERYENDSESSION message.
