Is the .NET Framework SDK Version 1.1 (for C#) available for download from Microsoft site, free for download?
Can I use it to make and market commercial applications, without restrictions? Moreover, can I develop full-fledged applications using it (of course the visual IDE will not be availabe if i understand correctly)?
I am forced to ask this question here because this SDK download is about 103 MB and the Microsoft site does not mention about the license conditions before the download is completed.
Thanks in advance.

Yes, you can develop and market applications written on the "free" version of the .NET Framework. Those are the exact same compilers used by the Visual Stduio IDE. The compilers are part of the Framework, not the IDE. There are no licensing restrictions.

Hi,
I have a problem deserializing xml into objects.
my class structure:
orderHeader
order
orderDetail
orderHeader has an arraylist of [order]
order has an arraylist of [orderDetail]
orderHeader and the arraylist of [order] is filled, but the arraylist of [orderDetail] remains empty.
this is the code i use to deserialize:
<br />
Dim serializer As New XmlSerializer(GetType(orderHeader))<br />
Dim fs As New FileStream("c:\schipUbnOrder.xml", FileMode.Open)<br />
Dim myOrderHeader As orderHeader<br />
myOrderHeader = CType(serializer.Deserialize(fs), orderHeader)<br />
What am i doing wrong ?
Thanks already
John

Hi,
Thanks for the reply, but i already found the problem:
the [orderDetail] arraylist in the [order] class was not initiated in the default constructor. Therefore he generates a nullReference...
It does know the type of the arraylist thanks to this code:
[XmlArray("orderLines")]
[XmlArrayItem("orderLine",typeof(orderDetail))]
public ArrayList orderDetail
{
get {return mOrderDetails;}
}
regards
John

Hi,
You can use .Net remoting for this purpose. The following link contain necessary information on .Net remoting.

When drawing text to the client area using the DrawString command. Is there a way of finding out what the new graphics point position is after the text is drawn?
What I am trying to do is Draw text to the screen which could take up any number of lines. After drawing the text I want to be able to draw something directly below the text. I need to be able to find the screen position to draw to once the text has been drawn so that I'm not drawing over the text.
Is there any way to do this??

I am familiar with ASP.NET C# for web development and have just now been learning windows forms development with the .NET framework/C#. However, I was wondering if anyone knew of a way to do caching in a windows form.
I am making a call to a web service and it takes a few seconds longer than I would like. Is it possible to store everything in a "System Cache" and then avoid calling the web service multiple times in the same execution of the program?
Thanks in advance

ASP.NET offers several places to store data, such as viewstate, session state, etc. In Windows Forms programming, if you want to cache anything, you'll need to write the code to do that yourself, using the System.Collections namespace. A hashtable is the best choice, to build a name/value pair. My approach is to write a class that maintains access to the underlying object ( a web service in your case ) and uses a hashtable to store values. The first time you access a property, or perhaps after a timeout, it reads from the web service. Every other time, it returns the cached value.

in the server side, i created a Lib class that has the implementation for the win32 API function that set the cursor position to (x,y)
[DllImport("user32.dll")]
public extern static int SetCursorPos(int x, int y);
public static int SetMousePos(int m,int n)
{
return SetCursorPos(m,n);
}
and i created a webserives and i imported the DLL file to use SetMousePos(x,y) function and i created a new Web Method that calls the SetMousePos(x,y); and passes the parameters to it, the returning values from SetMousePos(x,y) are ( "1" if the function executed right and "0" if it didnt"
in the client side, i added the webservice reference to my project and i called the WebMethod but it didnt work it returns 0 always,
I tried that in a windows Form and i called the SetMousePos when i pressed the button and it worked but it doesnt work with webservices
can u help plz

Well, I hope with all of my being that a web service is unable to change the position of my mouse cursor without my granting it the permission to run that sort of low level code.

Of course it didn't work! Web Service code executes remotely, not on the local machine. The SetMousePos function tried to set the position of the mouse pointer on the server, not your machine. But, since the account that the web service is running under a limited access account, it didn't have the rights to change the mouse cursor, so it failed.

but this is what i want, i want it to change the cursor position on the server, first i thought web services doen't call any Invoked win32 API function, so i tried to call the method that calls this Win32 API function
int flg;
[DllImport("wininet.dll")]
private extern static bool InternetGetConnectedState( out int Flags ,int Reserved);
public static bool Connected()
{
return InternetGetConnectedState( out flags,0);
}
this method returns true if the computer (the server in my case) is connected to the internet otherwise it returns flase..
I called the WebMethod from the client App that calles Connected() and it worked. it returned true and when i disconnect it returns fales
so why this method workes normally but the other method doesn't work, and if i have to give the Webservice some extra permeations, how can i do that

I'm going to recant my last statement, to a point. I don't think it's a permissions problem, but rather the fact that the Web Service is just that, a service. It doesn't have a desktop, a visible one anyway, to set the mouse cursor position on. Since it's running under IIS, you can't use the same techniques you can with a normal service to set it up for interaction with the visible desktop.

Hi!
A friend of mine needs some help with some custom controls for his current project, and I've offered to help him with this. I've just found an article here at codeproject that shows how to export C# controls as ActiveX object, which is great, since then I might use C# to help him out... but it's proven to not be all that easy. I've registered the controls using the "Register for COM interop" check box in the property sheet of the C# project, and I'm able to instantiate at least one of the controls in tstcon32. The program crashed when I tried to instantiate the other controls, but I'll look into that later. The problem is that his project is coded using Borland C++ Builder 6 which doesn't list my controls as registered ones. And I'm not able to add them as one would with other activex controls since there's no OCX file generated when the C# file is compiled... Is it possible to fix this in any way? Or will I have to make the controls in C++??

I dont know if i was just looking in the wrong place on MSDn for that or if it isnt what i need. I am at the point where i can open the browser from my app, but then i want it to find an html form field such as
<input name=user type=text>
and put some data in it
then find the
<input type=submit value=find user>
and "click" it.
is that something the HTML post can do? i mean i know it should be able to be done, i just can't find where to look to find out how. i hope i've cleared this up, does anyone know what i'm looking for????

Yes the POST reply is what your looking for,
It might be the case that you don't need to open a browser at all, if you just need to fill out a form.
Have a look at the WebRequest[^] class.

what i want to extract the non-file part from a url so that i could use it for further processing
for instance if there is a url like http://site.com/abc/efg/file.ext
i want to extract BOLD part from the Url,i could split w.r.t / and then check each chunk whether its a file or not,but i was looking for some built-in method for such task,Uri was working fine unless i encounter above mentioned problem

Hello Developers,
I want to create a rotated font, and I use the following code to achieve this, like in this sample (http://winfx.msdn.microsoft.com/library/default.asp?url=/library/en-us/dv_fxsamples/html/7c8b073b-5889-45e7-9a99-ebee39fe3b79.asp[^]), but using 1.1 framework.
Font CreateRotatedFont(int angle, Graphics g)
{
LOGFONT lf = new LOGFONT();
// scale a 12 point font for current screen DPI
lf.Height = (int)(-16f * g.DpiY / 96);
lf.Width = 0;
// rotation angle in tenths of degrees
lf.Escapement = angle * 10;
// Orientation == Escapement for mobile device OS
lf.Orientation = lf.Escapement;
lf.Weight = 0;
lf.Italic = 0;
lf.Underline = 0;
lf.StrikeOut = 0;
lf.CharSet = 0; //LogFontCharSet.Default;
lf.OutPrecision = 0;//LogFontPrecision.Default;
lf.ClipPrecision = 0;//LogFontClipPrecision.Default;
lf.Quality = 5;//LogFontQuality.ClearType;
lf.PitchAndFamily = 0;//LogFontPitchAndFamily.Default;
lf.FaceName = "Tahoma";
return System.Drawing.Font.FromLogFont(lf);
}
Am I doing something wrong in this code, or maybe someone did similar code once?
Thank you!
