Hi,
I have a little problem when I am trying to use the SoapClient class from WSE 2.0 sp 1. I have to write a .NET application that must access some webservices written in Perl. I respect with the MS QuickStart samples the code that I wrote look like this:
Uri destUri = new Uri(http://82.77.28.243/site/arl/soap.tr/arac/tkn.ars);
ADotNetClient client = new ADotNetClient(destUri);
where:
[SoapService("http://schemas.company.net/arl/soap.tr/arac")]
public class ADotNetClient : SoapClient
{
public LoginClient(Uri to) : base(to)
{
}
[SoapMethod("http://schemas.company.net/arl/soap.tr/arac/tkn")]
public SoapEnvelope LoginSoap(SoapEnvelope envelope)
{
return base.SendRequestResponse("http://schemas.company.net/arl/soap.tr/arac/tkn#Get", envelope);
}
}
When a try to call LoginSoap I receive an error. Trying to solve the problem I traced the message which sent to the PerlWebServer and I found somehow the problem which appear to be in the HTTP header. Normally the first line of the http header should lool like this:
POST /vonc/arl/soap.tr/arac/tkn HTTP/1.1
but in my case look like this:
POST http://82.77.28.243/vonc/arl/soap.tr/arac/tkn HTTP/1.1
Pls explain to my why appear this and how can possibly solve the problem.

i would ask u 1 question in every tutorial has properties i see the get and set methods then in set it says MyString =
value ; in any tutorial it is value so what it means and is it a default one?

value is the implicit parameter used in setting accessors and to add or remove event handlers.

It lets you easily define access functions for a variable
In C++ you'd have something like
private:
int myint;
public:
int myint_get()
{
return myint;
}
void myint_set(int newval)
{
if( do some kind of check to make sure the value is valid )
{
myint = newval;
do any processing that has to happen if myint changes
}
}
so in the main code, if you want to increment the value of myint you'd have to do something like obj.myint_set(obj.myint_get()+1); which is somewhat messy
In C# access functions are made much tidier, like so
private int myint;
public int MyInt
{
get
{
return myint;
}
set
{
if( do some kind of check to make sure the value is valid )
{
myint = value;
do any processing that has to happen if myint changes
}
}
}
in other words, to answer your question value is whatever gets passed into the set function, i.e. obj.MyInt = 42; --then value would be 42
this lets you do stuff like obj.MyInt++; and treat it as if you'd just declared a public variable in the first place (without any of the worry about messing up your value)
You can make a read only variable by omitting the set{} part, or make it write only by omitting the get{} part if you so desire
NOTE: This code was just written off the top of my head - it's not expected to actually compile

I just wanted to include that if you look at any property that is generated with a setter method, the parameter name of the variable is always generated as value. For example, if you look at the InnerXml property of the XmlElement class (randomly chosen) you will see the following:
public override void set_InnerXml(string value)
{
this.RemoveAllChildren();
XmlLoader loader1 = new XmlLoader();
loader1.LoadInnerXmlElement(this, value);
}
With this logic you will see that the properties in C# simply generate getter and setter method with method signatures like set_[PropertyName] and get_[PropertyName].

Hı, My name is sait. I have a problem for this Registry and Eventlog.
in this way, now I haven't logon administration. but I want to while not have an admin to know write and Read to Registry and Eventlog file? Do you understant me? sorry I little speak and write english! 
thank you very much... I wait to your answer...
Good evening...

You can read and write to certain areas of the eventlog and registry even if you are not logged in as an administrator.
For registry you can always read and write to HKEY-CURRENT-USER.
With the event log only administrators have access to the Security Log.
Does this help a little?

can any 1 solve this problem 4 me ?

There are two quick solutions:
1) Add the following line to AddRc():
test.TableName = "test";
2) OR change the following line in button1_Click()
DataTable Dtable = DS.Tables["test"].Copy();
to
DataTable Dtable = DS.Tables[0].Copy();
Essentially you're trying to reference a table called test which does not exist (even though the object you created was called test - it does not mean the table name will be set to "test").

hi
thanx 4 u r help this fixe the problem . but i have a new problem now which is :
when i click the button 4 the first time the row will be added to the datagrid and i can C it but when i click the button again nothing happen and no data added to the data grid ?!!! any idea ? ? ? ?
|

Having quickly looked at the code.. I changed the following:
1) You don't want to clone the dataset since you won't be updating the one that is linked to the control.
Change the line
this.DS= addRCDataSet.Clone();
to
this.DS= addRCDataSet;
2) I modified the whole button1_click() method to:
private void button1_Click(object sender, System.EventArgs e)
{
object[] values = new object[1];
values[0] = textBox1.Text;
DS.Tables["test"].Rows.Add(values);
}
This just seemed a lot simpler to me - your earlier method was giving me problems.

It would be good to know which line of your code produces the error.
Anyway, by the given error message it's obvious that you try to use an object which wasn't instanciated yet.
So look which line causes the error and verify if you instanciated every object used there.

Is there any chance in .NET to override standard look of Windows’ scroll bars (i.e. to make them be flat, change colors…) and then to attach them to standard controls: listbox, combobox, listview? Can I make my own scroll bar and attach it to mentioned controls?

Did you manage to solve your query? Because I would like to do the same! Please let me know!
Many thanks,

Hi...newbie here...yes it smells like an assignment but please if anyone can help with a formula on how to get this one.
My head is spinning....i've only got the inputs and im suppose to create a function not use the ones in the standard library.......pleasssse help with anything...................something......
^^^^^^^^^^^^^^^^
Write a function that takes the time as three integer arguments (hours, minutes and seconds) and returns the number of seconds since the last time the clock “struck 12.” Use this function in a program to calculate the amount of time in seconds between two times, both of which are within one 12-hour cycle of the clock.
|
|
|
|
|
Assuming you're only using 12 hour clocks and not 24 hour:
return (hour*60*60) + (minute*60) + second;
If my assumption is incorrect then you simply need to subtract 12 from hour if hour >= 12.
As for the second part - call the function twice and then take the absolute value of the difference of the two times.
|
|
|
|
|
Simply use the modulus operator to correct the hours value: (hour % 12)
The rest was already given by the previous post.

this is what i got...can anyone help integrating the formula suggested into this.........?
to make it simpler.....?
#include<iostream>
using std::cout;
using std::cin;
using std::endl;
int main ()
{
int time(int,int,int);
int h,h2; // 0-23
int m,m2; // 0-59
int s,s2; // 0 -59
cout <<"Please enter 2 times: "<<endl;
cout<<"enter="" hour="" for="" the="" 1st="" time:="" "<<endl;
="" cin="">> h;
cout <<"enter minute for the 1st time: "<<endl;
cin="">> m;
cout <<"enter seconds for the 1st time : "<<endl;
cin="">> s;
cout <<"Please enter the 2nd time: "<<endl;
cout<<"enter="" hour="" for="" the="" 2nd="" time:="" "<<endl;
="" cin="">> h2;
cout <<"enter minute for the 2nd time: "<<endl;
cin="">> m2;
cout <<"enter seconds for the 2nd time : "<<endl;
cin="">> s2;
cout <<"According to the times entered,"<< endl;
cout<<"the difference between the two times in seconds is "<<time(h,m,s)- time(h2,m2,s2)
="" <<"="" seconds."<<="" endl;
="" return="" 0;
}
int="" time(int="" hh,int="" mm,int="" ss)
{
="" int="" min="0,sec" =0,sec2="0;
" if="" (hh="">12)
min = hh * 60;
sec = min * 60; //converts hours to seconds
if (mm>0)
sec2 = mm * 60; //converts minutes to seconds
int x = sec + sec2+ss; //total seconds
return x; //returns total seconds

Hi newbie,
Well this sounds like a mathematical function that you would have to make something like -
public int returnSecondsSinceTwelve(int hour, int minute, int second)
{
int timeSinceTwelve = 0;
if(hour > 12)
{
timeSinceTwelve = hour - 12;
}
else if(hour < 12)
{
timeSinceTwelve = hour;
}
timeSinceTwelve = timeSinceTwelve * 60 * 60;
minute = minute * 60;
return timeSinceTwelve + minute + second;
}
i havent tried this function so i dont gaurantee that it will work (i just wrote it roughly and really quick) but the basic theory is - to get seconds out of an hour multiply it by 60 (minutes) and then again by 60 (seconds) - to get seconds out of an minute multiply it by 60. Then add these all up (including second which is already in the right format) and you will get the total seconds. Hope this clears thins up.

Hi,
Does itextSharp support editing an existing pdf file.
We have a pdf template file with placeholders for different values that needs to be replaced with the actuals programmatically.
Basically kind of "Find and Replace" text values.Is this possible by itextSharp from sourceforget.net or any other pdf writer/generators.
TIA

If you have questions specific to a particular product, then you need to ask on it's respective site. SourceForge has forums for each projects, so go to the iTextSharp project page and click on "Forums".
If that doesn't do what you need it to, there is another article on this site I just read the other day that may: A PDF Forms Parser[^]. There may be others as well, but you just need to search.

iTextSharp does not provide an option to EDIT an existing pdf file.
Here is a quote from their tutorial:
You can't 'parse' an existing PDF file using iText, you can only 'read' it page per page.
What does this mean?
The pdf format is just a canvas where text and graphics are placed without any structure information. As such there aren't any 'iText-objects' in a PDF file. In each page there will probably be a number of 'Strings', but you can't reconstruct a phrase or a paragraph using these strings. There are probably a number of lines drawn, but you can't retrieve a Table-object based on these lines. In short: parsing the content of a PDF-file is NOT POSSIBLE with iText. Post your question on the newsgroup news:
Also,
What iText DOES provide is the possibility to READ a PDF document and copy an entire page of this file into the PDF file you are constructing from scratch. This can be useful if you want to create a new document based on (an) existing document(s). You can add a Watermark, pagenumbers,...
You may want to check out http://itextsharp.sourceforge.net/tutorial/ch01.html[^]
