To convert byte -> octet and byte -> hex :

byte myByte = 250;
string octet = Convert.ToString(myByte, 8);
string hex = Convert.ToString(myByte, 16);

To send the ring tone, I think you must use the AT command from nokia, see the Manual.
Search it in nokia website for AT command.

Then use SerialPort class for writing AT command to phone.

But I gave an answer to 1 of the two conversions, surely that is allowed?

I am confused as why you need to convert a Byte to either octet of hex in order to send data? after all both Octet and Hex are just different was to display a byte value. If you want to convert a byte (or int) to string values for hex then...

string hex = myInt.ToString("X");//Convert to hex string

...I'm not sure of an easy way to convert an int to octet string thou sorry

FYI: octet is French for byte, so there is no conversion required at all. What you want is "octal" or base-8 notation.

After connecting to an instance of IE, i'm trying to control/monitor the events. So far everything works but the filedownload event handler. Anybody have any tips on how to do it? The following (C#) is the syntax for all of my event handlers.

myInternetExplorer.FileDownload += new SHDocVw.DWebBrowserEvents2_FileDownloadEventHandler(OnDownload);

Any clues/pointers would be helpful!

thanks

You can't make an installer force a reboot directly from visual studio project, you need to modify the installer that gets created.

A tool called [annoyingly] Orca is useful, it lets you modify the installer:

You'll need to do this every time you re-build the installer package Frown | :(

Create a floating object

Hi forum!!!

I have the next question...

i have in my proyect in c#, a form with a picturebox (with a image loaded), and I need to create over my image a floating object which I can to move over my image. this floating object is like the objects in power point (put a rectangle, circle, some shapes) to change its properties with the mouse (width, heigth,...)

How I can do it?

Re: Create a floating object

You can draw on picturebox control using the Graphics object. Here is an example code fragment:

 // Create the graphics object for the picturebox
Graphics gr = pictureBox1.CreateGraphics();

// Draw a red rectangle on the center of the picturebox
Rectangle rect = new Rectangle();
rect.X = pictureBox1.ClientRectangle.X + pictureBox1.ClientRectangle.Width / 4;
rect.Y = pictureBox1.ClientRectangle.Y + pictureBox1.ClientRectangle.Height / 4;
rect.Width = pictureBox1.ClientRectangle.Width / 2;
rect.Height = pictureBox1.ClientRectangle.Height / 2;
gr.DrawRectangle(new Pen(Color.Red), rect);

.....

You can use the MouseDown, MouseMove and MouseUp events for the picture box, to make the object floating or to change its width and height with the mouse.

you can use the event 'mousemove' 'mouseover' to catch it .
in mousemove event , you can get a parameter(e).
e.x is width, e.y is height

Hi, you can first creat a div, then let it move like this:

function Movediv() {
var div = document.getElementById(g_DivName);
var xx = new Array();
var speed = 1; //distance
var speed2 = 20; //interval time, 10ms
xx.push(0);
//xx.push((document.documentElement || document.body).offsetWidth - div.offsetWidth - 20);
xx.push((window.innerWidth || document.body.clientWidth) - div.offsetWidth - 30);
var x = parseInt(div.style.left.replace(/^(\d+).*?$/, "$1"));

div.style.left = x + speed * g_MoveDirection + "px";
if (x <= xx[0]) { g_nMoveDirection = 1; }
else if (x >= xx[1]) { g_MoveDirection = -1; }
//setTimeout("Movediv()", speed2);
}

Compatability problem with Transparency key

Hi friends,

I tried to draw graphics on a transparent form by using the Transparency key.

"this.BackColor = Color.Blue; this.TransparencyKey = BackColor;".

The problem is, it is working fine with Vista. But when I am using the same code to draw on XP, it is not working. I am using visual studio 2008, so is there a compatability problem?

Hmm.. I never used tranparency key before. But in XP, I use property Opacity for transparency. Set it from 0% to 100%.

9-Sep-09 23:48

Yeah, I tried the solution first by setting the opacity, but when I am setting the opacity to the from, the drawings (graphics) are also becoming opaque, thats why I used the Transparency key.

you want to set the form's background color to transparent.
1) so you can set the form to Irregular Form.
2) or you can set the form's background color to transparent

Which GUI Toolkit for variable User Interfaces and Mono-Compatibility

softwarejaeger9-Sep-09 22:08

softwarejaeger

9-Sep-09 22:08

Hello,

i want to make a very variable user interface for my applications, i would need to have the ability like in wpf to put graphics and contorls into my forms and arrange them without boundaries. In most GUI-toolkits you can only put your Controls into tables or other panels, but i want to arrange them freely.

Is there a GUI Toolkit for it? Is there one with Mono-Compatibility? Or is there a way to put Images over Images in Winforms too (2 transculent PNGs).

Another Problem is, that WinForms looks in Mono really Win95-like. Is there a control-kit which doesn't looks like that?

Many thanks
