I create a web service with an DelItem() method to delete a record of a table in SQL2000 database via a store procedure.
It works correctly itself but when i call it in my web application an error (UNAUTHORIZED) occurs.
Whats the problem?
---------------------------------------------
Exception Details: System.Net.WebException: The request failed with HTTP status 401: Unauthorized.
Source Error:
Line 59: [System.Web.Services.Protocols.SoapDocumentMethodAttribute("http://localhost/webservice/wsns/delitem",RequestNamespace="http://localhost/webservice/wsns",ResponseNamespace="http://localhost/webservice/wsns",Use=System.Web.Services.Description.SoapBindingUse.Literal,ParameterStyle=System.Web.Services.Protocols.SoapParameterStyle.Wrapped)]
Line 60: public string delitem(short code) {
Line 61: object[] results = this.Invoke("delitem", new object[] {
Line 62: code});
Line 63: return ((string)(results[0]));

Your webservice needs authentication and your client application failed to provide credentials.
On the web services client, set the Credentials property to some valid credentials, e.g., CredentialCache.DefaultCredentials.
Yes, even I am blogging now!

Or change the web service to allow anonymous acces. This can be done from
Administrative Tools | Internet Information Serives. Then right clicking and select Properties on web site. Click the "Directory Security" tab and then the top "Edit" button. From the here select the "Anonymous access" check box.
Real simple, eh?
Cheers,

hello i have a foreach loop that loops through each char in a string what i am wondering tho is how would i advance to the next char within the foreach loop without losing my current place within the string
|
|

You will have to use a for loop.. something like:
string str = "this is a test";<br />
<br />
for (int i = 0; i < str.Length; i++)<br />
{<br />
char currentChar = str[i];<br />
MessageBox.Show("Current Character = " + currentChar.ToString() + "\n\nCurrent Position = " + i.ToString());

i know what a for loop is i was just hoping there was someway to peek at the next char in a foreach and advance the loop when i needed to for ease i guess
|
|
|
|

Please refer to the code...hope u get some clue:
string temp = "ABCDEFGHIJ";
System.Diagnostics.Debug.WriteLine("for loop output");
for(int i = 0; i < temp.Length; i++)
{
char c = temp[i];
System.Diagnostics.Debug.WriteLine(i + " place char = "+ c);
}
System.Diagnostics.Debug.WriteLine("foreach loop output");
int j = 0;
foreach(char c in temp)
{
System.Diagnostics.Debug.WriteLine(j + " place char = "+ c);
j++;
}

I need a solution for reducing or removing the flicker in the user controls (some controls I made) ... I'm seeking an effectient way; so please if anyone know how to do it, please tell me ...
NOTE : I have already used the DoubleBuffer Style and still got some sort of flicker ... The controls are drawn from A to Z so it continue flickering and flickering  ...
Thanks for your time ....

For the control's painting have you used Graphics from PaintEventArgs?.
like for form Paining.....same as below code.
private void Form1_Paint(object sender, System.Windows.Forms.PaintEventArgs e)
{
Graphics g = e.Graphics;
g.DrawString("Happy X-Mas", this.Font, Brushes.Blue, 0,0);
}
Note: If you DONOT use Graphics from PaintEventArgs, there will always reamin flickering, I had the similar problem once, I solved it using the above approach.

I'm using the graphics supplied as a parameter in the OnPaint ; What really makes the control filkering more and more, is its nature as a container (such as the panel), When the control is drawn without any children controls, it works very good but when adding the children controls, it starts flickering in an unacceptable fashion ... Thanks for helping but I stell need some more IDEAS ...

This is the piece of code in Early Binding and works as expected.
---------------------------------------------------------------------------
using
ControlLicenseService LicenseInfoClient lic =new ControlLicenseService LicenseInfoClient();
lic.Initialize("sk26901CODA904O",10300);
if (lic.IsSuccess )
{
MessageBox.Show("Success");
}
else
MessageBox.Show("Failure");
This is my code in Late binding:
------------------------------------
Assembly asm = null;
Type PublishType = null;
try
{
string strPath = GetInstalledPath();
asm = Assembly.LoadFrom ("c:\\somefile.dll");
PublishType = asm.GetType("ControlLicenseService.LicenseInfoClient");
Object theObj = Activator.CreateInstance(PublishType);
// Array with Two members for passing the Parameter for Initialize method.
Type[] paramTypes = new Type[2];
paramTypes[0]= Type.GetType("System.String");
paramTypes[1]= Type.GetType("System.Int32");
// Get method info for Initialize( )
MethodInfo InitializeInfo =
PublishType.GetMethod("Initialize",paramTypes);
// Fill the array with the actual parameters
Object[] parameters = new Object[2];
parameters[0] = "sk26901CODA904O";
parameters[1] = 10300;
InitializeInfo.Invoke(theObj,parameters);
PropertyInfo pi = PublishType.GetProperty("IsSuccess");
string valu = pi.GetValue(theObj,null).ToString();
MessageBox.Show(valu);
}
Does there are any exceptions in reflections? What I found thru debugging was the parameters are setting properly n the late binding but the method is not invoked properly or it fails in the method.
Any idea ? or is the code wrong?

Sometimes I can associate file extensions with my application (a C# form based application), and sometimes I can't . And worse - I can't figure out what I change to lose or gain this capability.
Specifically what I'm referring to is being able to click on a file in explorer and have explorer start my application if the file extension is jpg. Sometimes I can right click on jpg files, select "Open With" and then "Chopse Program ..." and then browse to my program, select it - and - sometimes this works, and sometimes it doesn't. Anyone know what I'm missing?
Also, even when it does work, I only see the icon show on the list of applications that I can associate a file extension with - the name of the application has never shown up.

Hello,
For example the TabControl, if you select it, in the property window, under all the properties theres also a section where you can click on "Add Tab". I want to know how to add such link(buttons) to your user control. I got a tips on DesignerVerbs and I made this:
public virtual System.ComponentModel.Design.DesignerVerbCollection Verbs
{
get
{
verbs = new DesignerVerbCollection();
verbs.Add(new System.ComponentModel.Design.DesignerVerb("&Add Section", new EventHandler(OnAddSection)));
return verbs;
}
}
private void OnAddSection(object sender, EventArgs args)
{
System.Windows.Forms.MessageBox.Show("The first designer verb was invoked.");
}
but I'm not sure thats it, because now another property is added under misc called Verbs with a collection as value. Not what I wanted.
Tips and code is appreciated!
Thanks in advance!

I am unable to compile and build spart parser (spart_src.zip) by Jonathan de Halleux, written in C#.
In a case like this you should contact the author directly (best would be to use the article discussion board). Anyway, the article you're talking about has been updated on 2003-12-23 and there is a confirmed message on the article discussion board from 2003-12-26 that the build is broken. So it seems there is no complete version on CP right now. Also the web site mentioned by Jonathan seems to be down.
Best regards
