myLib have some code :
<br />
this.url = "myurl";<br />
userid = "myid";<br />
passwd = "mypwd";<br />
comment = "cat/etc/resolv.conf";<br />
<br />
[System.Web.Services.Protocols.SoapDocumentMethodAttribute<br />
("",RequestNamespace="urn:execute",ResponseNamespace="urn:myLib",Use=<br />
System.Web.Services.Description.SoapBindingUse.Encoded, ParameterStyle=<br />
System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]<br />
<br />
public string execute(string userid, string passwd, string command)<br />
{<br />
object [] results = this.Invoke("execute",new object[] { userid, passwd, command });<br />
return ((string)(results[0]));<br />
}<br />
and my application has code :
<br />
string result = myLib.execute(userid, passwd, command.Text);<br />
I don't understand [System.Web.Services.Protocols.SoapDocumentMethodAttribute
("",RequestNamespace="urn:execute",ResponseNamespace="urn:myLib",Use=
System.Web.Services.Description.SoapBindingUse.Encoded, ParameterStyle=
System.Web.Services.Protocols.SoapParameterStyle.Wrapped)] does and somebody can explain that , what 'this.Invoke("execute", new object[] {userid, passwd, command));' do???
please help me?? thanks

hi,
i want to do insert statement in access db. but, i found somethings wrong.
would anyone give a helping hand?
here is the code:
String strCmd = new String(' ', 1024);
strCmd = "insert into profile(id, interval, address) values(1,1, \"tuen moon\")";
OleDbCommand cmd = new OleDbCommand(strCmd, conn);
int result = cmd.ExecuteNonQuery();
there is a exception.
"Syntax error in INSERT INTO statement"
i can't see any syntax error on my sql statement...
anyone can help? is it related to MS Access?
thanks,
jim

bool switchB=true;
private void button1_Click(object sender, System.EventArgs e)
{
if(switchB==true)
{
<code>
switchB=false;
}
else if(switchB==false)
{
}
}
I have a set of 7 buttons, numbered from 0-7, right to left, and all their text set to "0".
now, all of the button's onclicks go to the above method...
As you can see, inside the for loop... Now all I need it to do is this...
Change the text of whatever (of the 8) buttons were clicked.

this works:
Button btn = null;
if(switchB==true){
<code> btn </code>= (Button)<code>sender</code>;
<code> btn</code>.Text = "<code>Persian Gulf</code>";
switchB = false;
}
Don't forget, that's Persian Gulf not Arabian gulf!

Ok, cool. That worked. I didn't know you could declare your own Button, like you can a variable...
I'm confused... whatever... thanks again.

Have you ever programmed before? You can declare a variable of any type you want. This is evident in every programming language. You can use generics or types for variables, fields, properties, function parameters, and whatever you choose.
Some languages like JavaScript/JScript may declare a variable type as var (a generic), but even it has a type - the type of whatever function or object filled it (like var d = new Date(); - d is now of type Date)
Similarily, the same is true in .NET (and Java and MFC). Every class in those frameworks (and some others) derives from Object (or CObject, etc.) If you assign a different type to a generic variable, the type is still that of the type you assigned it:
object o = new Button();
o is actually of type Button, even though it is declared as an Object. You could also declare that variable as a Button, or a Control, or any base class of the Button type. Casting that object doesn't change it - merely gives you access to the methods and properties defined for that class (or inherited by base classes). For example, it wouldn't matter if the variable was declared as a Object or a Button. If you called the ToString method, the method that is called is the one declared on Button because it overrided the method of a base class. This is typically (shall I say, "standard") object-oriented programming (OOP).
I recommend you pick up a good book on .NET programming, or even just OO programming. Looking at a lot of the questions that you've posted, you should also browse around the base class library (BCL) documentation that was installed with the .NET Framework SDK and Visual Studio .NET.
This isn't a slam, but a reminder that research is only half (if not more) of development. Guessing and getting other people to do the work is not going to teach you anything. Browsing around the .NET Framework library will at least familiarize you with what is available so you have some idea of what you could use in a given problem so you don't have to reinvent the wheel. A good book on OO will help you design efficient and effective code.

could you not add a universal handler for all of the buttons? then use
sender.GetType().Name="blabla"
Csharp™ the coder formally known as dynamic
Me.twins.duedate = DateTime.Now.AddDays(+17).ToLongDateString
Me.Birthday = DirectCast(Me.twins.DueDate, DateAndTime.SameDay)
|
|

here's a quick example i built for you...
<br />
private void Form1_Load(object sender, System.EventArgs e)<br />
{<br />
foreach(Control btn in this.Controls)<br />
{<br />
if(btn.GetType().Name=="Button")<br />
{<br />
btn.Click+=new System.EventHandler(this.Clicker);<br />
}<br />
}<br />
}<br />
<br />
private void Clicker(object sender, System.EventArgs e)<br />
{<br />
Button b=(Button)sender;<br />
MessageBox.Show(b.Name);<br />
}
hope it helps

Hello, I have a slight problem. I have an application written in Java, but i'm rewriting it to C# currently. Now i've run into some problems since some parts of the save procedure used java serialization (of a hashtable).
Of course I need to be able to still read files made with the java version, but how can this be done? basically I would need to decode the serialized java object. Is there any documentation to be found on this subject?
does anyone have an idea?

Yap: check on Sun's site if there is any doc on how the standard hashtables are serialized!
Once you know that,
open the files, and read them into a C# Hashtable as needed.
HTH,
F.O.R.

Keep in mind that the objects in the hashtable were also serialized. For the most part, if you were to use simply objects in a Java hashtable and save that to a file (I'm thinking just a simple test class with String members), you could also reverse engineer it. That wouldn't be so hard using your favorite hex editor. Depending on the complexity of the objects within it, though, that's another story.
If nothing else and worse comes to worse, you could always use the JNI concepts I cover in my article, Embedding .NET Controls in Java. The content of the article doesn't apply so much as the concept does - using JNI to bridge the gab between .NET and Java. A JNI Win32 DLL (not a managed assembly - Java won't know how to load it) to use Java calls to deserialize a hashtable and pass the members to .NET, or could even use late binding and the unmanaged CLR methods to get your .NET assembly to serialize the hashtable. Basically, this idea would be a one-time conversion utility (I recommend not overriding the old file though, or you should at least back it up).
Obviously, deserializing the hashtable would be preferred (and most likely not hard to do), but the latter idea could be handy in a worse-case scenario.

thanks for the help. fortunately my hashtable is expected to contain strings only and i've found out they have a very simple serialization scheme so I'm starting to get the hang of it now.. But there are still a couple of "mystic" bytes in there =)

here's the code...
private void menuItem2_Click(object sender, System.EventArgs e)
{
StreamWriter fout;
if(this.saveFileDialog1.ShowDialog()==DialogResult.OK)
{
fout= new StreamWriter (new FileStream(this.saveFileDialog1.FileName, FileMode.Create));
<code>fout.Write(this.listBoxLog.Items.ToString());</code> fout.Close();
}
}
Now the line in bold...
What would I put to make it write out the whole listBox...
Or would I have to put it in an array or something first...?
/\ |_ E X E GG

|

I think this works:
foreach(Object <code>o</code> in <code>this</code>.<code>listBoxLog</code>.<code>Items</code>)
fout.Write((<code>string</code>)<code>o</code>);
Don't forget, that's Persian Gulf not Arabian gulf!

Are dynamic textboxes or labels possible? Like for example you want to get a list of names and you want to put it in labels but you wouldnt know how many names will be sent?

Dynamic controls are very easy to implement. For example:
Label lblName ;
foreach(string sName in arrName)
{
lblName = New Label();
lblName.Text = sName;
myForm.Controls.Add(lblName);
}

If you use any CLS-compliant language you'll need the .NET redistributable on the target machine. An alternative is to use something like Macromedia Director or Macromedia Flash (make a standalone exe). You could also use the now obsolete VB6 (and hope that they have the VB runtime DLLs)
The safest approach would be to use HTML pages (you can then have gifs, jpgs, swf etc in sub directories)
