The only way I can think to do this is to enable/disable the title bar on the form in the "LostFocus" and "GotFocus" events. This way when the form is not in focus, it has a title bar and can be tabbed to. Then when it gets tabbed to the title bar disappears before the user sees it. The only problem here is that when there are two applications on the window side by side, you could lose focus without actually covering up the app so the user may see the title bar every now and then.

I wonder if u can help me in solving the following problem:
I want to divide a number by 10 and get the result as the highest number.
Let me explain with following examples:
13/10 = 2 and
27/10 = 3
I am using Math.Ceiling to get the higher value, but the problem is that it only works for double value. I have the following code:
decimal weight = 20.1;
decimal MaxWeight = 20;
double weightInDouble = Convert.ToDouble(weight);
double PackageWeight = Convert.ToDouble(MaxWeight);
double NumberOfPackagesNeeded = Math.Ceiling(weightInDouble / PackageWeight);
However, the problem I am facing is that if the weight=20.1 and I convert it to double value, I get 40.2, and this would give me a wrong answer.
So how can I get the higher value when I divide two decimal values.
regards

Have you actually tried what you are saying here? Im probably not getting you right but calling Convert.ToDouble(someDecimalValue) doesn't give you a value which is doubled. It just converts a number in a decimal format into a double format (which means double precision floating point number). Except for some very slight rounding issues the value will not be changed.

I am using VS.net debugger to run through my code. And when I convert 20.1 to double, VS.net debugger shows the weightInDouble=40.2
I also get the wrong answer:
double NumberOfPackagesNeeded = Math.Ceiling(20.1/ 20);
Should give me 2... but currently I am getting 3
regards

Check it again. Following code outputs "2" twice:
decimal weight = (decimal)20.1;
decimal MaxWeight = 20;
double weightInDouble = Convert.ToDouble(weight);
double PackageWeight = Convert.ToDouble(MaxWeight);
double NumberOfPackagesNeeded = Math.Ceiling(weightInDouble / PackageWeight);
Console.WriteLine(NumberOfPackagesNeeded);
NumberOfPackagesNeeded = Math.Ceiling(20.1/ 20);
Console.WriteLine(NumberOfPackagesNeeded);
Note that I changed the first line of code from our original post. The way you posted it gives a compilation error because the compiler identifies 20.1 as a double value which cannot be implicitely casted to decimal. Thats why I had to insert an explicit cast.

my mistake my mistake my mistake
After re-checking my code, I realised that 40.2 is the correct amount. I am getting "weight" value from database and I was expecting to get 20.1 instead of 40.2. So when I got 40.2, I thought there was something wrong with my application code.
Anyway, thanks again

Hi,
Can someone please tell me how can I scroll an image?and how can I manipulate its size so that it's adjust it according to the monitor size of the user's monitor?
Thanks,
E.A.

You scroll an image by changing which part of the image you draw. You change it's display size by drawing it to the size of the window you're drawing on.

![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif) Hi,
I am having a problem with using the IHTMLElementRender in my C# Application.
First I redefine IHTMLElementRender as below
[Guid("3050f669-98b5-11cf-bb82-00aa00bdce0b"),
InterfaceType(ComInterfaceType.InterfaceIsIUnknown),
ComVisible(true),
ComImport]
interface IHTMLElementRender
{
void DrawToDC([In] IntPtr hDC);
void SetDocumentPrinter([In, MarshalAs(UnmanagedType.BStr)] string bstrPrinterName, [In] IntPtr hDC);
On the main form of the application I am have the folowing code
InternetExplorer ie=new InternetExplorer();
object v1="",v2="",v3="",v4="";
ie.Visible=true;
string strUrl="http://blogs.msdn.com/rfarber/archive/2004/10/12/240943.aspx";
ie.Navigate(strUrl,ref v1,ref v2,ref v3,ref v4);
Thread.Sleep(5000);
IHTMLDocument2 idoc=(IHTMLDocument2)ie.Document;
//IHTMLElement el=(IHTMLElement)idoc.body;
//IHTMLElementRender ren=(IHTMLElementRender)el;//System.InvalidCastException
IHTMLElementRender ren=(IHTMLElementRender)idoc.body.GetType().GetInterface("IHTMLElementRender",true);//ren returns as null
Is there any solutions to my problem?
thaks for any help.

Dear all,
Please let me know how to capture the screen of the other systems which are under LAN from my system.
|
|
|
|
|
You have to install a program on each system that can capture the screen and send it to your system.

Hello
I have an abstract class and a second class that inherits.
My question is.
Which class executes first when I do this in the constructor
public void NoAbstractClassConstructor(): base();
I have several methods in the abstract class and i would like to know if they executes first.
Thanks in advance
Jose

Huh? If you wanted to know the order of execution of constructors, then the base class constructor executes first before the derived class's. Not 100%[^] true, because field initializers run before the base class constructor is called, but you can safely assume it is true for most cases.

Hi friends,
I want to access all members of Color enum one by one . any one can help me?
|
|
|
|
|
You are looking for Enum.GetNames[^]. Pass any enum type as a parameter and it returns a n array of strings containing the names of the enum elements. In your case, you need to call it as Enum.GetNames(typeof(Color));.
Hope this helps.
Regards
Senthil

How can I Draw a string in reverse color of background?It is easy using code like this
private void tb_Paint(object sender, PaintEventArgs e)<br />
{<br />
string text = ((TouchButton)sender).strName;<br />
FontFamily fontFamily = new FontFamily("Times New Roman");<br />
Font font = new Font(fontFamily,12,FontStyle.Bold,GraphicsUnit.Point);<br />
Rectangle rect = new Rectangle(this.iHorizentalSpacing ,<br />
this.iVerticalSpacing , this.iWidth - 2 * this.iHorizentalSpacing<br />
, this.iHeight - 2 * this.iVerticalSpacing);<br />
e.Graphics.FillRectangle(Brushes.Black,rect);<br />
e.Graphics.DrawString(text,font,Brushes.White,rect);<br />
}
but I Want to generate colors and they reverses manually.

Does negating the hex value of the background color work? Something like
Color bgColor = Color.Black;
g.FillRectangle(new SolidBrush(bgColor), 0, 0, this.Width, this.Height);
int val = bgColor.ToArgb();
val = ~val;
Color foreColor = Color.FromArgb((0x000000FF & (val >> 16)), (0x000000FF & (val >> 8)) , (0x000000FF & (val)));
g.FillRectangle(new SolidBrush(foreColor), 0, 0, 100, 100);

Dear All,
There is a squid server on WinXP (127.0.0.1:8081).
I have a C# application that I want to it redirect ALL HTTP request to squid(transparent proxy).
(application and squid run on same system)
I use GlobalProxySelection and below code in my application, but dont work.
Uri proxyURI = new Uri("http://127.0.0.1:8081");
GlobalProxySelection.Select = new WebProxy(proxyURI);
How can I redirect ALL http request to this proxy server?
Is correct this question!? Can I do it on windows OS?

I have this problem too.
Can everybody help us?

If you are running a transparent proxy, you dont need to change anything on the clients. The proxy get automatically used for outgoing requests to port 80 as directed by iptables in linux. You can verify this by inspecting the http repsonse headers. Squid should add 1 or 2 headers to the response. If your are using this for webservices you mite wanna disable caching on the webservice else your requests will be cached by squid.

Hi
I want to redirect all my network traffic especially UDP through proxy server. I want to change contents of some of my packets and then send that packet to the destination. Any idea how I can do this. I am not good in C, any solutions in C# will be a plus as I have to complete it early.
