Is there any Tool Bar control which is by default quite similar to Standard I.E explorer tool bar,which contains back forward stop refresh buttons etc.Creating such tool bar on our own will take time,so is there any available tool bar control like this.

No. You can have a prebuilt toolbar that supplies the buttons, but there's no way it can know what your using those buttons for and supply the code for them. You'll still have to write code behind the button click events so they'll actually do something.

Is it possible to stop people from being able to decompile a C# program or to 'rip' the code out of a compiled application?

Thanks.

there are many obfuscation programs are available in market which you can use to secure your source code.

a good defination of obfuscator from google : )
"Obfuscator is a program that garbles a source either by encryption or by substitution of codes. This means that the source to be compiled is hard to understand and hard to debug. But during runtime it is decrypted as pure source."

You can make it harder by using an obfuscator. An obfuscator takes the IL and mangles it so that it is tough for decompilers to figure out the original source, while still maintaining the original logic of the program.

All said and done, with enough time and resources, a motivated person can still decompile your code.

Listing Local Users/Groups

I managed to retrieve LOCAL user & groups and list them in a listbox. Now I need to find out which localusers are "memberof" a local group. With Active Directory (using LDAP) it works, but it won't work with localuser/groups.

The last I tried:

DirectoryEntry group = new DirectoryEntry("WinNT://127.0.0.1/Administrators", "", "", AuthenticationTypes.None);<br />
<br />
foreach(object dn in group.Properties["member"] )<br />
{<br />
Console.WriteLine(dn);<br />
}

Who knows what I'm doing wrong ? Or does somebody knows the right we to handle this?

Thanks

Jeah, I did it (stolen from a example from codeproject.com) Sigh | :sigh:

StringCollection userGps = new StringCollection();<br />
DirectoryEntry obDirEnt = new DirectoryEntry("WinNT://" + "127.0.0.1" + "/" + "Eric");<br />
object obGps = obDirEnt.Invoke("Groups");<br />
if (null != obGps)<br />
{<br />
  foreach (object obGp in (IEnumerable)obGps)<br />
  {<br />
    DirectoryEntry obGpEnt = new DirectoryEntry(obGp);<br />
    userGps.Add(obGpEnt.Name);<br />
  }<br />
}

Now I only ask, why does is take so long to 'invoke' ? Is there anyway to make this go faster ?

What do you mean by "when I activate this function, then doubleclick event not fire"? Are you trying to doubleclick on something WHILE your doing a Drag & Drop operation?

We need a better explanation of what your trying to do.

.NET Framework SDK Version 1.1 for C#

Anonymous1-May-05 21:30

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.

deserializing xml

JohnBeton1-May-05 20:53

1-May-05 20:53

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

I don't think that it can deserialize the inner array list because it doesn't know the type.

Why not use something like MycroXaml[^] to do the deserialization? Poke tongue | ;-P

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;}
}

Hi,

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

I think remoting is a bit heavy for that! Although if stuff gets complex you probably better off using remoting.

Easiest would probably be to create a TCP connection and just use the BinaryFormatter to (de)serialize objects. Be aware the files tend to have ALOT of padding in them, so use a byte compressor to make them smaller. Have a look at my libbz2 article. Works nicely Smile | :)

How do you find the graphics new point position??

OnlyTaz1-May-05 18:01

OnlyTaz

1-May-05 18:01

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??

Re: How do you find the graphics new point position??

leppie1-May-05 20:19

Use MeasureString to find the bounds of the text you want to draw. The you can either pass adjusted parameters for next DrawString, or use TranslateTransform to adjust the 'point position'.

Windows forms cache

1-May-05 15:04

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
