There are no problems for load/open a solution or project and complie and run the projects. But the problems occurs when i create a new project or solution. After new project, set the type of the application and set the path, and then "OK", I got an error: "Microsoft JScript Compile error". Would you please tell me what is my mistake? Thanks in advance! chen Re: New project problem?

Other than that, I believe this is not a programming question, and would suggest you to post either on a public MS VS.NET NG (likely to get an answer), or even http://support.microsoft.com How low can you go ?

Best Regards, chen Re: New project problem? Stephane Rodriguez.29-Oct-02 19:33 Stephane Rodriguez. 29-Oct-02 19:33  In the Windows control panel, double-click the Internet Options icon. Then, in the security tab, click the "Local Intranet zone" (I believe you the issue is not from the untrusted Internet zone), and either : - in the dropdown list, choose Low - or check the radio buttons so that everything is accepted and enabled. Just to make sure you are not restricting anything to execute. How low can you go ? (MS rant) Soapsuds and "Invalid schema data" Anonymous29-Oct-02 12:40 Anonymous 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 Re: Soapsuds and "Invalid schema data" Senkwe Chanda31-Oct-02 2:00 Senkwe Chanda 31-Oct-02 2:00  Could be that MyForm isn't serializable. *shrug* What are you trying to do ASP.NET can never fail as working with it is like fitting bras to supermodels - it's one pleasure after the next - David Wulff Converting from Java to C# problem.. Ed K29-Oct-02 12:18 Ed K 29-Oct-02 12:18  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 /> or <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?

Christian Graus29-Oct-02 15:28 Christian Graus 29-Oct-02 15:28  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 ?

Re: Converting from Java to C# problem.. leppie31-Oct-02 6:09 leppie 31-Oct-02 6:09  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 "There are no stupid question's, just stupid people." Re: Converting from Java to C# problem.. Stephane Rodriguez.29-Oct-02 19:16 Stephane Rodriguez. 29-Oct-02 19:16  You are just showing how little you know about Java. I don't know much either, but I can read the reference doc. 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'; PS : Java being a joke? Ha ha!!!!

Anonymous30-Oct-02 11:23 Anonymous 30-Oct-02 11:23  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.

I know that when I obtain data in a DataTable, each of the DataColumn objects contain information about the column including the column name and the data type, however, the type that it provides is a System.* C# type. Is there any way to determine the SQL Server type name (e.g. int, smallint, etc.) programmatically?

Re: Determing SQL Server Type from C# perlmunger29-Oct-02 10:54 perlmunger 29-Oct-02 10:54  I've been looking in there through the debugger as well as in the DataTable and DataColumn and I don't see anything that would tell me the type or the length of the individual columns. Do you know of something more specific? -Matt ------------------------------------------ The 3 great virtues of a programmer: Laziness, Impatience, and Hubris. --Larry Wall Re: Determing SQL Server Type from C# leppie29-Oct-02 11:05 leppie 29-Oct-02 11:05  Your dataset contains the mapping from SQL types to .NET types, if you dont have a dataset (which I doubt), just get one of the data adapters auto generate u one. Then double click that file (the .xsd file) and it will show the equivalent SQL types. For the length of each type (of each parameter), that too get auto generated if you are using stored procedures. Hope this helps "There are no stupid question's, just stupid people." Re: Determing SQL Server Type from C# perlmunger29-Oct-02 11:11 perlmunger 29-Oct-02 11:11  You say that "Your dataset contains the mapping from SQL types to .NET types...". I do have a DataSet, I just don't know where this mapping is that you are referring to. What member of the DataSet contains this information? You understand that I want to obtain this info programmatically, right? Thanks again. -Matt ------------------------------------------ The 3 great virtues of a programmer: Laziness, Impatience, and Hubris. --Larry Wall Re: Determing SQL Server Type from C# leppie29-Oct-02 11:39 leppie 29-Oct-02 11:39  perlmunger wrote: You understand that I want to obtain this info programmatically, right? No, but i do now <dataset instance="">.<tablename>.Columns["Usersorwhatever"].....oh damn I have no idea, where that takes place... You can find out the .NET types, so I assume the cast from SQL to .NET is auto, inserting values u need the SqlType and width though, so I'm not sure how this is done. I will look tomorrow, I need some desperate sleep "There are no stupid question's, just stupid people."
