what MSDN is trying to indicate here on this tutorial, ref this page: Walkthrough: Creating a SQL Server Express Database.I cannot make this happen in VS2008 SQL Server 3.5 ?

A few years ago I have been busy creating this application but it didn't succeed, now Im coming back to it and similar problems occur. Basically I use SetPixel on a given window to draw a line, work fine, but the line goes away as the window redraws itself.The problem: I have been putting timers and threads on it to make sure the line is being drawn. Is there any way to make a loop to make a certain thing happen about 10-30 times without taking in too much memory/CPU?

I am new user of Crystal Reports and experienced at using VS2008 (VB). I have a big gap that I have found no explanation on bridging. There must be some type of import process that I have been unable to find.
I built a report using SQL Server 2005 (Business Intelligence Dev Studio) and it works. I need to use the report in a VS2008 (VB) project. How do I get it into my VB project and call it? The SQL project creates a report with an .rdl definition file. I think the VB project requires an .rpt file. How do I import it into the VB project?
I created a Visual basic DLL in Visual Studio 2008 on my computer( not server). I want to copy this DLL to the server.I want web pages to call this DLL What do I need to install on the server (2003) to make this DLL work? I think I would need

I want to create a setup which requires Microsoft SQL Server 2005 and .NET Framework 3.5. If this software isn't installed, the Setup should offer the user to install them now.
Write code or use tableadaptors, bindingsources, dataset, etc.? I have experience with the older ways i.e. connection strings, ado code, sql, etc. but was hoping the newer tools in vs would make the user interface easier and more flexible. So far i have been disappointed. Am I wrong and I am missing something? Am I alone in this opinion or ? What is your past experience in VB and have you found vb.net to be a step forward in db user interface design? if your answer is yes then what is the easiest way to put a table record count into a text box? should i bypass all the new stuff/objects ( adaptors, binding sources, navigators, designers, etc) and just write code or what?
After developing using the Excel Interop with .Net for a while, i have become increasingly annoyed with the how many "odd things" happen - such as this question i posted earlier.
I have a server which has around 300+ users on it. Though the problem is that its coded in VB6, and if somebody has a bad ping, everybody has a bad ping. I need a tunneling server which will tunnel the incoming and outgoing connections and make there ping appear to be 0 in the server. Client to Server, Server to Client.
I'm wondering what would happen if my program was used say, on a computer with a chinese keyboard? I assume the text box controls will be fine, but sometimes I compare english strings.. such as "!" and "@" and a few other things.
I have a form with seven tickboxes - one for each day of the week - each one saved in my.settings.monday, my.settings.tuesday, etc Now I need to check if something should happen today and the code I'm using (below) seems very longwinded. Can anyone help 'tidy it up'?
If Now.DayOfWeek = DayOfWeek.Monday And My.Settings.monday = True Then 'do it End If
Strange problem: This code gives the appearance the I have 'Split' 1 button into 2 (B -> B(1) & B(2)) and then can 'Join' them back(B(1) & B(2) disappear and B returns). All this works fine, 'cept when I try to declare the only container where this can happen. The 'Control-S' part works as long as the lower portion is commented out, when I uncomment the lower portion 'Control-J' neither part works - the code skips down to the msgbox -
If e.Modifiers = Keys.Control AndAlso e.KeyCode = Keys.S Then If DirectCast(sender, Button).Parent Is flp1 Then MakeButton(sender.text & "(1)") 'sub that makes the button passing the text thru
I have a website that i've been working on for about a year now.Recently, it's started throwing System.AccessViolationException every now and then, in my dev machine, mostly, when I was away from the machine.I haven't changed anything on the server code in weeks, since I've been working 100% on the Javascript part, and this error started appearing recently.
Also, the code I'm doing is 100% managed. I'm not doing any interop, calling strange DLLs, nothing. It's pure VB.Net, so I don't see how I could be generating one of these myself.Now, I've been using this new machine for a couple of months, and it's not working 100% right. Every 2 or 3 days I'm getting a blue screen for example. I haven't had time to diagnose it properly, but I'm suspecting I may have a faulty RAM chip.
I have an application in which i have a database .mdf file in directory which i use a connection string to give a path of to access it, which means without installing sql server i can access database. Connection string below to access this database(.mdf) which placed in the directory.
dim con as sqlconnection = New SqlConnection("Data Source=.SQLExpress;integrated security=true;attachdbfilename=|DataDirectory|Universal_data.mdf;user instance=true")
Now the question is that if i access this .mdf file without installing sql server, i also want to access to this .mdf file on other computer(client) after creating DSN or any other connectivity tool.
Let me know you that when i install sql server 2000 or 2005 i create SA user name and password which i use to create DSN on client computer and give SA username and password in the connection string that successfully works and client get access to sql server, connection string is below.
Dim serv = "MY-LAPTOP" dim con as sqlconnection = new sqlconnection("Data Source=" & serv & ";Initial Catalog=clinic;Persist Security Info=True;User ID=sa")
I only need to know that my application access .mdf file without installing sql server works fine on a single computer, and i want to give access to this .mdf file on other clients without installing sql server on server computer (like i mentioned above paragraph) how will do it.....
I have made 2 application server/client. I want to remote the client from server for example if I press 1 then one action should happen in client, if 2 then another action should occur. How can I do it? I think I should use select statment

I have this function I put together with help online and it works just fine until the program runs over night. I don't think it is night time that is the problem, just the long run time. I take bitmaps and place text on them then convert them to icons so that the image can be used on the system tray.
