Hi friends, I have one web service it works fine in localhost when I uploaded in server I got tested I am unable to see that and I got Internal Server Error 500.
What may be the fault?
I just published the WebService and hosted in server through FTP and later I checked I am getting above error.
Please help me.

Error 500 is the generic failure code because something went wrong with a component, not with the web server itself. In the case of a web service, it usually means your code threw an unhandled exception.

When the error is 500, that means it's an internal error, meaning internal to the service - the service threw an exception that was not caught.
Look in the Windows event logs on the service to see what went wrong.
Also, try:
- Go to menu Tools/Internet Options in your IE.
- Click on the Advanced tab, uncheck "Show friendly HTTP error messages" option and click Ok.
- Try accessing your web page again. Now you will see much more meaningful error message which will help you to troubleshoot the problem.
Other few possibilities:
There might be an issue in the way you have hosted your service. May be multiple config files?
Further, since you have not shared the type of webservice or what framework application it is, it can also be a cross domain policy issue after hosting on other server.

Hi
I have created a crystal report using Visual Studio 2005 C#/Asp.net, i have output like good average poor. I need to replace those with images or tick (right) mark using formula fields like
if{Read}="Good" then
"some image / tick mark"
else if {Read}="Average" then
"some image / tick mark"
else
"some image / tick mark".
If anybody knows, please reply me.
Thanks in advance

You can use conditional formula for the same.

BTW, this is not .NET Framework related question as such to be posted here in this section.

In the old days you could add a simple setup project to youe VS solution, add project output, set some properties and you had a usable setup project with no problems.
Nowadays - the setup build always complains about a mismatch in the target version (no matter what I do) - it often can't find some dependencies and usually needs to be deleted and done from scratch every time I do an update to the main project.
It used to be so simple.

See if this works:
1. Select installer project
2. Click on the icon at the top "Launch Conditions Editor"
3. Under Launch Conditions, Select ".Net framework" on the right
4. In "Properties" Select "Version" you will see a drop down.
5. Change the framework to your target framework
Try!

Brilliant, thank you very much. Why has endless google searching never provided such a clear answer?
Once again, thank you very much

Can anyone suggest a tool that operates similar to the Split Container tool? According to Microsoft[^] the SplitContainer tool still has an unfixed bug as of VS2005. I am using VS2010 and it's still not fixed keeps causing program to crash on every build.
Is there another tool that does something similar to what the Split Container does without the MS bug?
All I want to create in my VB form is a header, footer, and contents in the body so I can be able to dock them all.
Thanks.

reply 3
topic 2
reply 1
reply 2
reply 3
like this .
i have binded the topics in datalist . but dont know how to do the other part . can anyone help me out
this is the code i used for datalist
Sub binddata5()
Dim mycommand As New SqlCommand("SELECT * from alltopics", con)
con.Open()
topics.DataSource = mycommand.ExecuteReader
topics.DataBind()
con.Close()
datalist design
<asp:DataList ID="topics" runat="server" DataKeyField="id"
RepeatColumns="1">
<ItemTemplate>
<div>  <strong><asp:Label
ID="detail" runat="server" Text='<%#Container.DataItem("topicdetails")%>'></asp:Label></strong>   on   <asp:Label ID="date" runat="server" Text='<%#Container.DataItem("ondate")%>'></asp:Label></td></tr>
</div>
</ItemTemplate>
</asp:DataList>
the replys to any topics are stored in another table named tblreply.

You might get a better response by posting this in the correct forum[^].

Hi Guys,
I have a small big question.
What does the
using System
using System.Data
actually do when a program is executing?
To the best of my knowledge it loads a DLL related to those namespaces into the memory and then accesses the methods,but recently I came to know that <pre lang="c#">using</pre> tells the system to use the namespace and access the methods,but how is it possible to use the namespace and access the methods without actually loading the DLL into program execution memory?This recently came up in a discussion with a team member and he shattered my belief in .NET

The using keyword just makes your code a little simpler by allowing you to not specify namespaces when accessing classes. For example, if you have this class:
namespace Tester
{
class Test
{
private void TestMethod()
{
}
}
}
Without a using statement, you would use it like this:
var x = new Tester.Test();
With a using statement, you can have:
using Tester;
var x = new Test();
Provided you don't have a class name collision (which namespaces are used to avoid in the first place), you end up with 'simpler' code (for a given value of simpler). However, they aren't essential.
The DLL references are managed by the project file and then passed directly to the compiler, not using these statements.
Incidently, this isn't a specifically C# thing, the using namespace construct in C++ works in the same way.
Does that answer your question?

Got it,but does that load the DLL into the program memory while it is executing ?
for example in DataAccess.dll I have:
Using System.Data;
namespace A
{
Class DataAccess
{
}
}
in business layer/application project I refer the DataAccess DLL and I say
using A;
using System;
namespace B
{
Class c
{
DataAccess daObj = new DataAccess();
}
}
does the above line load the dll System.Data into the execution of the program when class C instance is accessed as we are accessing DataAccess class which refers to System.Data?

Generally speaking a DLL will be loaded at the first method call whose code is part of the DLL. Thus in your example above it will be loaded at the call to the DataAccess() constructor. However, there is lots of optimisation in .NET so it is quite possible it gets loaded through some 'look ahead' code to speed up the program.

Ok,so that means even if refer to the name spaces in multiple project also the DLL gets loaded only once.
For example referring to the Microsoft.Practices.EnterpriseLibrary.Data in business layer and data access layer will ensure that DLL having the namespace is loaded only once through out the entire program execution.

This has nothing to do with the using statement, or with the number of projects that it is used in. A DLL is a code library that is used by an executable program, and is loaded into memory when some code in the executable makes a call to one of its methods. Having a using statement in your source code merely allows the compiler to satisfy references to methods or classes that are not defined within any of the source modules of the project. However, if no direct references are made from the program that contains the using statement, then the associated DLL will not be loaded.

So referring the namespace in multiple project/class libraries does not affect the number of times a DLL into memory.
Something like referring to
Microsoft.Practices.EnterpriseLibrary.Data in BusinessLayer.DLL and DataAccess.DLL,will ensure that .NET loads the
Microsoft.Practices.EnterpriseLibrary.Data.dll only once ?

It doesn't "do" anything, it simply instructs the compiler where to look (in referenced DLL's or in .NET language, "assemblies"). They aren't evaluated during runtime at all, it's only used in the preprocessor during the linking phase of the compilation process.
Like the other poster said, if you don't use the "using" statement, you have to explicitly identify where to find certain functions in the included assemblies. It essentially just saves a lot of typing as stated.
Oddly enough, the "using" statement can also be used to re-assign namespaces and class names. You can use it to "alias" namespaces.
Another "using" keyword is to limit the scope of a variable and do automatic clean-up, like:
using (SolidBrush sb = new SolidBrush(Color.Red))
{
//Use the solid brush here
}
//Here the solid brush no longer exists, and the object is correctly disposed.
