Hey Guys, I posted this on another forum with no luck. I figured I'd give it a try here too. If you know a solution... please don't be shy!!
---
I've been tasked with creating a webservice. It is useful to pass some parameters as custom objects. These custom objects are defined in a seperate assembly I'll refer to as SS. Both the webservice and the application consuming the web service reference the assembly SS. My problem is that the application consuming the service is changing the type of parameters. The following may help explain...
Assembly SS defines a User object (SS.User)
Web Service references assembly SS
Web Method takes SS.User as a parameter
WebMethod(SS.User TheUser) {
...
}
Application references assembly SS, I want to pass SS.User as a parameter to the web service but when I consume the webservice the method signature looks like this...
Service.WebMethod(TheApplication.TheWebServiceName.User)
My first thought was to create a SS.User object within the application then cast to TheApplication.TheWebServiceName.User then pass it. However, I get a compliation error as that cast is not allowed.
Any thoughts?? Is this expected behavior for some reason I don't understand??
---------------
this next part is my reply to a post, so it's not quite in context but adds some depth.
---------------
Anyways, yes. That I know. The object definition exists on both webservice side and on the application side. Both the application and the webservice independantly reference the SS assembly. The object data should just be serialized and passed to the service, then the object can be recreated on the server. Am I right??
Why when I consume the webservice does the webmethod signature not look like...
WebMethod(SS.User) ??? It looks like WebMethod(ApplicationNamespace.WebServiceName.User). And I can't cast from SS.User to ApplicationNamespace.WebServiceName.User.
This is maddening, because I swear I've done this before with no issues. GAR!

anwyays, thanks in advance for any replies

The application that is consuming the webservice does not need to pass an object of type SS.User. The webservice itself defines a proxy class that gets returned (TheApplication.TheWebServiceName.User).
You should be able to return a class of this type, i think.

OK, I see what you are saying. Does this mean that what I want to do is not really possible in the way I want to do it?

Hi
How to extract text from already existing captcha image.I have some captcha images(jpg format) with me,from that images i have to read the letters one by one and convert them as a string.
|
|
|
|
|
Generally speaking the point of captcha images is that its hard to do this. I would have to ask what it is you need it for.
|
|
|
|
|
From my point of view not possible ........
Easily you can't get text from image
Might be there are third party tools available check for that option
Thanks and Regards

All server controls that you use when you are developing a web application are web controls.
Most web controls support data binding in one form or another. If you choose to use the controls this way depends on if it suits what you want to accomplish.

The Formview option allows you to edit a row in a table, add a new row in a table, and delete a row in a table. How do you set up a formview where only the edit and new functions are enable but a user cannot delete a record?

What is the point of using data sources such as SqlDataSource or ObjectDataSource?
Consider a simple example of a web page with a dropdown list used to filter the content of a pageable, sortable GridView. Each control needs a data source and that results in two calls to SQL Server. We are also told to keep the number of "round trips" to SQL Server to a minimum, for best performance. These scenarios are incompatible (although the difference in my example is trivial).
The only solution I have spotted is to make a single call to a compound SQL Server stored procedure and to put the results in a dataset (a repeater cannot be used for a pageable, sortable GridView) and bind each control to the appropriate table in the dataset. The disadvantage to this method is that I now have to code the GridView Sorting and PageIndexChanging events rather than just supplying attributes for that control.

The objectDataSource is a very tool. It allows you to bind collection of objects to a gridview instead of always using a dataset or a datatable, dataview. I wrote and article on the objectdatasource and the gridview. Take a look at it and let me know what you think?
http://www.codeproject.com/useritems/GridViewObjectDataSource.asp[^]
I am currently using something close to what I showed in this article in production now. The objects and the gridview it self are a lot more complex, but the basic function is the same.

Use HttpRequest and response object
HttpWebRequest myHttpWebRequest = (HttpWebRequest)WebRequest.Create(URL);
HttpWebResponse response = (HttpWebResponse)myHttpWebRequest.GetResponse();
resStream = response.GetResponseStream();
re = new StreamReader(resStream);
Store the streamreader as you want you can also set cookies and Proxy in this aproach i think this might helpfull
Thanks and Regards

The problem is that I want to bind a data grid or a repeater in a background thread coz the binding process is a time consuming task that might slow down the response. I already binded the grid in the background thread but the problem is to update the UI from that thread.

hello to all,
i m working on a project which have functionality of chat room. If any new user comes then the new user must show on the page on client side which is already opened , without any post back. so please tell me how to send messages/alerts from server to client side.
with regards ,

a) you can't do this directly, once connection is closed there is no way for the server to connect to the client.
b) you can use an HTTP streaming technique where the connection is never closed and the server flushes javascript down it (look it up on ajaxpatterns.org)
c) use an Ajax request at regular time intervals to check for recent activity
d) please don't ask for code its too complicated

Hi,
I am using ASP.NET 2005. In my project I am using CrystalReport which cotains 50 columns. At the runtime it binds as per the query.
Suppose, as per the query there are 5 columns so it binds with 5 columns. If it gets 20 columns then it binds with 20 columns, like that, but at the time of printing(by using the print button of the CrystalReportViewer ToolBar) it prints upto the length of CrystalReportViewer ToolBar showing on the Browser.
Also there is a problem it shows all the columns binds at runtime in IE, not in Mozila/Netscape. In mozila/Netscape it shows only upto the length of the CrystalReportViewer ToolBar.
Please help.
Thanks & regards

I want to have a File uploader inside a grid view control. I have bound this grid view to a datasource, so can I use the file uploader inside the gridview? I will have to writer manual coding to upload the file, isn't it?
can somebody tell me how I can sent the filename of the uploaded file to the datasource parameter??
thanks for any answer!!!

You can put a file uploader in a gridview control, you just need to use a Item Template for the column you want it to be in.
Here is some sample code from Microsoft help:
Visual Basic
Protected Sub Page_Load(ByVal sender As Object,
ByVal e As System.EventArgs) Handles Me.Load
If IsPostBack Then
Dim path As String = Server.MapPath("~/UploadedImages/")
Dim fileOK As Boolean = False
If FileUpload1.HasFile Then
Dim fileExtension As String
fileExtension = System.IO.Path. _
GetExtension(FileUpload1.FileName).ToLower()
Dim allowedExtensions As String() = _
{".jpg", ".jpeg", ".png", ".gif"}
For i As Integer = 0 To allowedExtensions.Length - 1
If fileExtension = allowedExtensions(i) Then
fileOK = True
End If
Next
If fileOK Then
Try
FileUpload1.PostedFile.SaveAs(path & _
FileUpload1.FileName)
Label1.Text = "File uploaded!"
Catch ex As Exception
Label1.Text = "File could not be uploaded."
End Try
Else
Label1.Text = "Cannot accept files of this type."
End If
End If
End If
End Sub
Hope that helps.
Ben
C#
protected void Page_Load(object sender, EventArgs e)
{
if(IsPostBack)
{
Boolean fileOK = false;
String path = Server.MapPath("~/UploadedImages/");
if (FileUpload1.HasFile)
{
String fileExtension =
System.IO.Path.GetExtension(FileUpload1.FileName).ToLower();
String[] allowedExtensions =
{".gif", ".png", ".jpeg", ".jpg"};
for (int i = 0; i < allowedExtensions.Length; i++)
{
if (fileExtension == allowedExtensions[i])
{
fileOK = true;
}
}
}
if (fileOK)
{
try
{
FileUpload1.PostedFile.SaveAs(path
+ FileUpload1.FileName);
Label1.Text = "File uploaded!";
}
catch (Exception ex)
{
Label1.Text = "File could not be uploaded.";
}
}
else
{
Label1.Text = "Cannot accept files of this type.";
}
}
}

Hi dears,
each user in my website can upload her photo into a directory named 'UserAvatar' . when a user wants to delete her photo an error occured with this message : access to the path c:\domains\mywebsite\UserAvatar\1.jpg is denied.
to fix this problem I got Write access role to ASPNET user for UserAvatar directory. the code is :
<br />
System.IO.DirectoryInfo dInfo = new DirectoryInfo(path);<br />
System.Security.AccessControl.DirectorySecurity dSecurity = dInfo.GetAccessControl();<br />
dSecurity.AddAccessRule(new System.Security.AccessControl.FileSystemAccessRule("ASPNET",System.Security.AccessControl.FileSystemRights.Write,System.Security.AccessControl.AccessControlType.Allow));<br />
dInfo.SetAccessControl(dSecurity);<br />
but the error was not fixed.
What should I do ???
thx,

Unless your ASPNET user has the appropriate access, you probably won't be able to set this programatically (and if they do have access, then you won't need to...)
Also, and i could be wrong about this, but will they not need modify rights to delete something?
