Creating XML Schemas In .Net?
Apr 14, 2010
I've been trying to create an XML schema that describes the types used in an XML document I've created but have been having some trouble understanding what exactly I need to do. I'm using VB.Net and would much prefer to do things the right way (i.e by using the appropriate api calls) but I can't figure out which ones to use. Granted, I'm new to XML Schemas but I thought it would be as easy as creating the initial XML document for which I need the schema (which was a breeze).

In my database I have three schemas:
Schema1
Schema2
Schema3
Objects are separated out into each of these schemas depending on that objects function, which I thought was a good way of doing things. This in turn leaves no objects in dbo except the default objects from the model database which I have not modified.When I try to reference a stored procedure from code, whilst specifying its a stored procedure, I receive a Stored Procedure Not Found error. When I change the CommandType back to text, the code then works.
I don't have the code to had, but it looks something like this (written off the top of my head, so dont expect it to compile):

I currently have a sofware with 80 customers.All share the same database structure, when data are differents.We got 5 database for each customer.Today, we have named instances, so the program is accessing to Bdd with something like :
Connect to 127.0.0.1/CUSTOMER1
select * from base1..table1
Now, we need to change, we got many instances.The idea is to have unique SQLSERVER instance, obviously i want to avoid changing the code (VB.NET).Just tried to play with schemas and users, seems to be an option, but since the schema is under the database, in can't make it works :
Connect to 127.0.0.1/GLOBAL_INSTANCE as specific user (customer1)
select * from base1..table1 -> error @ this point
When THIS works :
Connect to 127.0.0.1/GLOBAL_INSTANCE as specific user (customer1)
Use Base1
select * from base1..table1 / or select * from table1
I can easily script some user or schema creation, and change connection strings for all customers, but i can't really change All requests: huge number.

I only have a very basic knowledge of VB but am trying. Basically I want to run a script that will add this website to the trusted site of users. We will have hundreds who need this and want to create a script to speed it along. I will be adding other things to the script as time goes on but this is the first step.

I'm looking to create an API for a website I have built. The API will be built in ASP.Net - probably using VB and will need to be consumed by multiple platforms including PHP. I've read a bit about REST vs. SOAP APIs and am confused about which route I should go. I also need some examples and frameworks I can use to get started.

I am trying to learn how to create a DLL in C (using Visual C++ 2010) for use in Visual Basic (2008 Express). I am a novice programmer, so please bear with me. My objective is to learn how to do starting with a very simple function, and I foundC++.html This examples presented in that tutorial are for Visual C++ 6 and VB6. I know there are differences between VB6 and VB2008, so maybe this is why I am running into problems following this example. In Visual C++, I created the DLL as a Win32 project. The function is simply summing two integers. I put the function "sum" in the source file "dllmain.cpp."

Is there any C# .NET ORM that can create databases? It should be capable of creating MS + MySQL + PostGre + Oracle databases at least.And I don't mean tables or schemas, I mean the database only.I use nHibernate, but it can only create tables and schemas, and query/insert but not creating the database itself.

I'm building a simple udp lan chat application in vb.net and I'm wondering how I should split my packets. Each sent packet should have like an id, a username and ip address from where it's coming and maybe also a command part for like join or leave to update my userlist and a text message. I'd like to know what is the easiest way to put all this in a simple packet then easily split and access different parts from it when it's received. thanks.I'm using UDP since this is only in lan so i'm broadcasting to *.*.*.255
What I want to know is what would be the most easy and powerful way to format my packets so they include a username , an id, a command and a text message, then the user receiving it decrypt it to show only the message written by which user or if it's a command like join or leave to show the appropriate message of joining and add the user to the list for exemple.

I have a vb.net web app, and I need to give my users the facility to download a ms-word .doc file. This file needs to be created dynamically, and should contain some bold text and a table.
I've come across this code, which builds a .doc file, and lets you download it:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strFileName As String = "GenerateDocument" + ".doc"
[Code]....
...but I don't know how to make the text bold, or create a table. I'm sure there's a better way.

I want to create a big list box that has lots of default values in many lines so they can then be edited later.Right now I have in my initializer:
Dim counter As Integer = 0
For counter = 0 To counter = totalNumber
listBoxThingy.Items(counter) = ("DEFAULT DETAILS TO BE COMPLETED")
Next
with my list box called listBoxThingy and totalNumber a previously defined constant of how many items I want in my list box.yet when I try to run the code I always just end up with the first list value containing the text.Even if I put a counter=counter+1 it still only gives me the one completed value of my list box?

How can I create a confirmation popup box into my Windows Form project? I use SQL Server Compact and Visual Studio 2008 Pro.At the moment I have some buttons and operations that delete selected rows straight from my database.
What I want to do, is have those buttons continue with the coded operation if the user clicks "OK" on the confirmation box.The box should be like the MsgBox, but with two selections: "OK" and "CANCEL".
P.S. I have several places to include that confirmation operation.

I'm trying to develop 2 companion applications. One application will be a FileSystemWatcher service application that will create/maintain a database containing file metadata (file properties) from a specific folder structure on the user's C drive. The other application is executed by the user which contains edit boxes pertaining to the metadata. As the user enters data in the edit boxes, the code will execute an SQL statement which in turn will display a list of file matching the entered criteria.
I'm thinking about using Microsoft Access as the database since all users have it but I'm willing to use another database format as long as it something intrinsic to the Windows XP 64 bit system (i.e. I don't want to install another database application in order to utilize its database format). So, do you have a suggestion on a database format? Do you have some pointers or links, on how to create database file and tables on the fly? Should I use DAO or ADO or something else? I'd prefer to work in VB.NET.

I created a new class project. I added a new COM object.The .ddl contains a single Public Function and one Public method. The method contains one line of code, a msgbox.I have "Register for COM interop" checked in the Project>Configuration>Compile page.I have ComVisible(true) in the AsseblyInfo.vb file.I use RegAsm to register the .dll and the .tlbI have used RegAsm to create a .reg file and then imorted successfully into the registry. If I open Excel, and go to Macro I cannot add the .dll as a refernce. The exact message I get is "Can't add a refernce to a specified file".I can reference the .tlb file and the Intelisense works. However, when the Excel Macro code runs I get the error, "Can't find file".I don't really expect anyone to download it to solve my problem. But if you become as frustrated as I am, I thought it might help to see the actual files. Be aware that I enclosed the .reg file from the RegAsm process. You can view it by opening notepad first and browsing for it. Do not click on the .reg file as I think that might modify your registry.

I've no problem dragging and dropping controls to a form, but what I am trying to do at the moment is create a simple label and display it at run time. Since the form doesn't exist at compile time, it isn't shown as a member of my basic form in the drop down on VB2008 and, of course, doesn't appear before the program is run.No problem creating the label and assigning property values (size, position and text etc.) in my program, but for some reason I cannot get it to display. Checked inherited properties such as visible and everything looks ok. No exceptions are thrown, all is well but the label never appears.Here's the code for display...label 2 is an existing visible label, a member of the form. Perhaps I am goofing in not making label3 a member of the form as well?
'place label near label 2
label3.Location = New Point(Me.Label2.Location.X + 20, Me.Label2.Location.Y + 20)
label3.Size = New Size(75, 75)
label3.Text = "here I am, Ma!"

Im new to programming and I'm having a problem with an university assignment.I need to control a pneumatic system through a vb app and i want to create a log in which I save all operations. I have a textbox_log and everytime something happens a new line in that text box appears.
I want that text box to save it self automatically in a txt file everytime a new line is written, but the problem is that I can only save the whole text box at a time! And i want to add just the new line to the txt file. Is that even possible?
