That is the way I do it. It may sound like a lot of work but crystal is quirky unless you do things there way.

CodeDom Type cast bug

Ever tried to make an property with the type of what you think should be Nullable<Single> a.k.a. Single?.
CodeDom will make cast this as Nullable<float>.

In short i cant seem to find anything on the net about this bug.
heres an test script:

CodeMemberProperty MyProperty = new CodeMemberProperty();
MyProperty.Type = new CodeTypeReference(typeof( Nullable<Single> )); // please notice the type
MyProperty.Name = "MySingleValue";
MyProperty.Attributes = MemberAttributes.Public | MemberAttributes.Final;

this will generate this:

public Nullable<float> MySingleValue
{ 
...
}

Has anyone any fix for this ???

With great code, comes great complexity, so keep it simple stupid... $Shucks | :-\$ $Shucks | :-\$

The c# float keyword is a System.Single?

I read it again, you're missing the point. float is C# syntactic sugar for the .NET type System.Single. They are one and the same thing.

If you're wondering why CodeDom changes your definition of float to System.Single its because CodeDom is language agnostic and the float keyword is only relevant to C#

UPS!!!!!

I did actualy find the solution to this... its because im an old VB developer but havent been using this for some years now...

Single is float in C# terms BUT in VB.Net its still Single.

So if i look in the VB generated code its an Single and in the C# generated code its Float.

My mistake...

I let it rest here...

Thanks for hammering my head, with the correct answer...

Http basic authentication issue

Hello everyone,

I am using IIS 6.0 and I am going to using the built-in function of basic authentication of IIS.

To authenticate, we must have user name and password. After some search, I am still confused where are the user name and password coming from? From Windows existing user account or somewhere else?

thanks in advance,
George

You can create user accounts on the machine or domain and then assign the security to the directories using standard windows security features. Basic authentication is not recommended for domain accounts as they are sent in plain text. BTW, I think this is a web dev question.

Hi Ennis,

1.

I understand how to create user account for local machine, but how to create user account for a domain? Any guides or documents?

2.

"assign the security to the directories using standard windows security features" -- not sure which management function do you mean, confused -- both Windows Server and IIS has a couple of various account management dialogs. Could you post some links or documents about what do you mean "assign the security to the directories using standard windows security features" please?

regards,
George

Call a .NET 2.0 library from a .NET 1.1 Library [modified]

Title says it all really, is it possible to call a .NET 2 library from a .NET 1.1 library?

The obvious and immediate answer is no, as the 1.1 library will be running in a 1.1 AppDomain that does not include the 2.0 framework. However is there anyway to "bridge" across, maybe remoting/custom socket server?

Haven't tested Remoting (although I think it is possible) but low level socket communication is definitely functioning.

Which class are you using to read webpages? If it is HttpWebRequest, then have a look at Credentials property.

Web Service XML Tag Rename

il_manti25-Sep-08 1:21

il_manti

25-Sep-08 1:21

Hi all,

I am developing a couple of web services for work. Most of the methods return custom classes but I want one of them to just return a 'string' (either "OK" or "NOTOK").

The problem is that, whilst with custom classes the webservice's XML's tags are named according to the variable name (for example: <hotelsummary><hotelid>5 ... where HotelSummary is a type but HotelID is the variable name), with strings the XML returned is <string>OK.

Is it possible to rename the tags to display, for example, <hotelcheck>OK instead of the datatype?

Thanks a lot.
