The trackbar can trivially be used to get a changing value. The real question is, what motion sensitivity level ?

Is there a way that I can import multiple projects (csproj, vbproj) at one time. As we all know vs2005 has a add project to solution option, but I cannot select multiple projects at once. I have a lot of projects and importing one at a time get tedious very quickly. So if there is any plugin/app/workaround please let me know.

Is there .NET wrappers for shared memory ?
I'm using .NET 1.1, and I just need to have a counter variable (Integer type) that needs to be accessed from different processes of the same program.
Think it this way, when a program runs, it increments this counter once. So at any time, the counter value is the number of current instances of the same program.

Hello, my name is Joan Miramontes, and im actually developing an application using the upnp stuff,
this is for a project for my BA D,
... so i have been using the upnp intels tools to get familiarized with them, in order to develop an application with c#,
the objective is to develop a control point, the control point need to have the posibility as well as one of the tools of intels of be aware of all the activity of the devices and be capable of control them, also it will be able of .. show the device, like if it was the device, in the other hand also build the devices... in order that the control point can control them, or should i say use them.
Well the thing here so far is thath i already know more or less how to build the device, im using the intel tools(the device builder and author service ) and just add the c# code that i need on every device. my prob here is that i have no idea on how make the control point, how to make the application that discovers the devices, and be able to control them or use the services that each one has... how to make the functions or the classes... or if its some already build it, where to find them or use them...
i forget to mention that all the applications im developing is for windows so im using projects on the .net application with forms and all the graphic stuff.
I hope that someone will be able to help me...

This isn't a C# question but this link will help you
http://www.computerhope.com/datehlp.htm[^]
I use batch files A LOT and they can do thing in two or three lines that a 300k C# app can't...

Hi,
I Have a Problem with this code ; below code is in turbo c++ and don't Know How To Convert it to c#2.0 code ?
#define COM 0x3f8
void Init_Serial(unsigned int Parity)
{
//Init Serial
int c;
outp(COM+3,0x80);//DLAB=1
outp(COM,0x0c); //Baud rate 9600
outp(COM+1,0x00);
outp(COM+3,Parity);
c= inp(COM+5);

http://msdn2.microsoft.com/en-us/library/c8zc5kah.aspx[^]
The above link is an example showing how to use serial ports in C#. It will show you how to setup, open, send data, and so on...
It is even easier than C++ in WindowsNT; though not as easy as Win 9X (read DOS) days with direct hardware access...

i saw that theres a way to host an internet explorer window inside winform application and also that i can host any application that has an activex like adobe acrobat, microsoft word, excel etc.
how can i (if at all) create a winform that can host any application ? a window that just enables me to run every regular application that i have inside it ?
thanx,
|
|
|
|
|
ActiveX is via interop with COM and for IE I'd suggest the "Web Browser" control (it is just IE)
|
|
|
|
|
for ie hosting on my winform im indeed using webform control, and for other apps that arrive with activex i can add the activex to my winform. my question is, how can i host other applications that doesnt arrive with activex ?
and another question: i used the code on this website to produce a transparent and clickthrough enabled, but i wish to have controls on the page that arent transparent and clickthrough, how can i acheive this ?
thanx,
|

From what I know/understand you can only use COM and "managed" (read .NET code) inside a C# project.
(note ActiveX is just a small part of COM)
If the it is possible to host non-COM objects I don't know how, if you' just wish to start another process then http://blogs.msdn.com/csharpfaq/archive/2004/06/01/146375.aspx[^] will help you...
I'm not sure what you mean by "wish to have controls on the page that arent transparent and clickthrough"
Do you want to have a form with a button of a z-index of 1 and overlay say a picture box with a z-index of 2 but when you click on the picture box where the button is location it will process a click on the button?

You have to launch the other application, wait for it's message pump to start, then grab it's main window handle and, using a P/Invoke call to the Win32 API function SetParent, change it's parent window to a host control on your form, like a Panel:
[DllImport("user32.dll", EntryPoint = "SetParent", SetLastError = true)]
private static extern IntPtr SetParent(IntPtr hwndChild, IntPtr hwndParent);
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
SetParent(p.MainWindowHandle, panel1.Handle);
WARNING! This will not work for every application out there! It's dependant on the hosted application rending it's own window. Using this technique CAN and WILL cause rendering problems with these applications and there's nothing you can do about it.
The hosted application will act just like it does if opened on the desktop. The user can minimize the app, resize it's window, yada, yada, yada, inside your application window, just like your app was the Desktop. They can even CLOSE THE HOSTED APPLICATION, and there's nothing you can do to stop that from hanppening!

You can't. Like I said in the article, it's the entire form, including all of it's child controls, or nothing.

Hello,
I'm building a base class to hold information taken from a robot movement file.
This means I have several lines, each with a set of points, and sometimes commands, between the points. Each point has some data (coordinates, orientation, zone, speed, work object, and a few more).
I'm using Eran Kampf's Sharp3D math library.
I would like a sugestion on how to implement the base class.
So far, I've done the following:
using Sharp3D.Math.Core
using Sharp3D.Math.Geometry3D
namespace ModelClass
{
#region Class constants
public enum Linetypes
{
undefined = -1,
laser = 0,
water = 1,
glue = 2,
primer = 3,
rough = 4
}
public enum Polysides
{
undefined = -5,
none = -1,
right = 0,
left = 1
}
#endregion
public class Point7D
{
// Represents a point in 3D space
Vector3F vector;
// Represents the quaternion of vector associated with point
QuaternionD quaternion;
// Point name descriptor
string name;
}
(...)
public class RobotPoint : Point7D
{
#region Constants
public enum zones
{
undefined,
fine,
z0,
z1,
z5
}
public enum speeds
{
undefined,
v5,
v10,
v100,
v1000
}
const string ActiveTool = "ActiveTool";
const string AuxPointData = "[0,0,0,0],[9E+09,9E+09,9E+09,9E+09,9E+09,9E+09]]";
#endregion
#region Internal fields
// Workplace definition
string workplace;
// Tool defined for the point
string tool;
// Zone definition
zones zone;
// Speed definition
speeds speed;
#endregion
}
public class PolyLine7D
{
#region Internal Fields
List<RobotPoint> pointList;
string name;
Linetypes type;
Polysides polyside;
#endregion
}
public class Model
{
#region Internal Fields
List<PolyLine7D> _ModelPolylines;
string _ModelFileName;
#endregion
}
}
Should the class PolyLine implement itself a static method for creating a list, instead of having the Model class do it?
Same question for the Model class if I want to have more than one file opened at the same time? In such case, I would create a Hashtable, with the _ModelFileName as a key.
Thanks for any help you can give me.

Hi guys,
I need some help please, example I have a string as follows T12322322232O, how do I parse everything between T and O using regex?
Please help.
sasa

If you mean you want to capture "everything between T and O using regex", then something like
"T(?'Data'.*)O" should work. If the regex Matches, there'll be a Group named "Data" whose Value contains the digits.
If that's not what you mean, then please post more details.

This sounds like a homework problem...
look for how to check for start and end (it is on MSDN)

hi, can anyone tell me how I could make c# search an xml file (i.e an RSS feed) for one of the components in the file (such as the title)
thanks,
Jacob

hmm, what i ment was like, i guess more like a dictionary, i was just saying rss to make it easyer, but it didnt,
say i have a dictionary and i have like
<dictionary>
<word>
<wordString>Example</wordString>
<Description>i duno =P</Description>
</word>
<word>
<wordString>Chair</wordString>
<Description>you sit on it</Description>
</word>
</dictionary>
so you would search for 1 word instead of of ts of words.

i want it so if i search "chair", it comes up with the description of the chair, and if i search Example it comes up with the description

if you use System.Xml you can do something like
XmlDocument xmlDoc = new XmlDocument();
xmlDoc.Load("http://www.someDomain.com/rssfile.rss");
XmlNodeList myList = xmlDoc.GetElementsByTagName("title");
foreach (XmlNode x in myList)
{
Console.WriteLine(x.Value);
}

What I posted will find every tag of that name
Example:
<rootElement>
<title>1</title>
<title>2</title>
<title>3</title>
<title>4</title>
<title>5</title>
<title>6</title>
<title>7</title>
<title>8</title>
<title>9</title>
</rootElement>
would output the following to the console
1
2
3
4
5
6
7
8
9
If you wish to use sub elements the example you posted then after the .getElementsByTagName("word")
check each node the node list as before see if there is more than one use .ChildNodes.Count on each value in the node list. If it is > 1 then it has more an just a text node under it. To goto the first child use .FirstChild to move down one level to <wordString> and .NextSibling to goto the <Description> tag
oh and hint hint
if .NextSibling == .LastChild then your at the end
