Re: Soapsuds and "Invalid schema data"

29-Oct-02 12:40

I have an object derived from MarshalByRefObject. Here's my problem:
If I have:

public class TheTransfer : System.MarshalByRefObject, IRemoting
{
public Form theForm;
//more blablabla
}
and run Soapsuds on the assembly it works fine. But if I use a class derived from Form, it won't. I get "Invalid schema data, Value cannot be null".

public class MyForm : Form
{
}
public class TheTransfer : System.MarshalByRefObject, IRemoting
{
public MyForm theForm;
}
Did anybody see this before?

Thanks

Could be that MyForm isn't serializable. *shrug* What are you trying to do Smile | :)

Converting from Java to C# problem..

I am converting a java app to C# and the passwords were encrypted with an algorithm written in java which uses the following to convert from a char to an int. Does anyone know the equivalent for C#?

<br />
int result = Character.getNumericValue('b'); // returns 11<br />

The 'equivalent' in C# returns different results...

<br />
double d12 = Char.GetNumericValue('b'); // returns -1.0????!!!!<br />

<br />
int i12 = Convert.ToInt32('b'); // returns 98<br />

What is the cause (other than java being a joke!) and how can I get the correct result?

Thanks,

I can't think of any reason, in any context, for 'b' to be '11'. I know capital A is 65 in ASCII, I'm not sure if lowercase b is ASCII 98. In any case, why don't you just subtract 87 ? Or is it not just for lowercase letters ?

I was about to do that then the meeting started so I fired off the question to see if anyone had run across it. I'm going to try that in the morning and walk the keyboard and see if everything fits. If not...do some sort of lookup.

Have you checked out MS's Java to C# convertor? Last time I checked it was still in early beta and didnt do such a good job (think it only supports Java 1.1), but it definately looked handy Smile | :)

You are just showing how little you know about Java. I don't know much either, but I can read the reference doc. Frown | :(

In short, Character.getNumericValue returns a code from an internal vm table known as the UAT (Unicode Attribute Table). As a result, this returns what you may call "weird" numbers.

To get the unicode from a char, you just need to cast it.

int unicodevalue = (int) 'b';

Hi All,
Is it possible to create an Access DB "on the fly" using ADO? If not is there any other method?
Thanks,

I wanted to do just that without having to include an interop assembly. I just created a blank db in Access and added it as a resource to my project. Then whenever I wanted to create a new blank db I just created a new file and streamed out the binary resource data for the mdb. Probably wouldn't get your program a "Designed for" Windows sticker, but it works.
