Problem connecting to SQL ServerI am new to all this... it is been a titanic struggle consuming hours & days & .... I am trying to create an SQL database programatically. But my code stalls before it gets started, and can't establish a connection to SQL Server. Here is my code: ======================================================== Sub MakeDatabase() Dim cn As New SqlConnection, cmd As New SqlCommand Dim connect$, sql$ connect$ = "Data Source=(local); Integrated Security=SSPI; Initial Catalog=;" cn.ConnectionString = Connect$ Try cn.Open() Catch ae As SqlException MsgBox(ae.Message.ToString, MsgBoxStyle.Critical, "SQL Connection") Exit Sub End Try sql$ = "CREATE DATABASE Cf" cmd.Connection = cn cmd.CommandText = sql$ cmd.ExecuteNonQuery() cn.Close() End Sub This thing stalls and can't connect, giving me an error #5. The error message suggest that my installed SQL might not allow "remote access". But I checked and it does. I am using VB 2005 Express and SQL 2005 Express. <b**@datasync.com> wrote in message

If your SQL Server instance is anonymous, don't add the \SqlExpress. Also had issues here with (local). Replacing (local) with either of the above fixed the connection. Thanks! That was the problem all along.

When you installed SQL Server 2005 Express did you take the default of installing a named instance? (The install wants to create a named instance named SQLExpress). If so, then try changing the data source in the connect string to: Data Source=(local)\SQLExpress; Kerry Moorman Show quoteHide quote "b**@datasync.com" wrote: > Can anyone help me connect to SQL Server??? > > I am new to all this... it is been a titanic struggle consuming hours & > > days & .... > > I am trying to create an SQL database programatically.

Express install. Frankly, when I installed it I didn't really know exactly what was going on... This is my first engagement/battle with Sql Server. Thanks so much.

Have a look at this sample on our website. http://www.vb-tips.com/default.aspx?ID=e76b8450-4c8a-4662-8f41-d6dda3c888c8 I think there is more in than you need, but the information you can use. You are the first one who uses still sql$ by the way in these newsgroups and I have seen much. There is nothing wrong with that, however as written tomorrow by GhostAD, you don't write a program for the computers, write it to let others know what you are doing.

When I had sent my both messages and had read the answers from Peter and Kerry I saw as well the answer to your problem. For that there was no need for me to sent another message. Your code is however in a very personal style: good readable probably by VB diehards, but not as we see code today. That was what I did mean with my text about the mystring$. To say it in other words the old literals are not so common anymore. In my opinion( but not mine alone) is one of the first commands to create a program using a program language as VBNet, is to make it maintainable by others.

I'm glad you brought that up -- I am just in love with those "old literals". I guess you mean by that that Dim sql as String is preferred to Dim sql$ I think the last form is so much better. Especially when you see people doing this: Dim strSql See what I mean? (A lot of people must like the "sql$" approach, because I notice that MS (after threatening to drop this capability) kept it in VB.NET all the way through VB.NET 2005.

It is in my idea not consistent (the last format we don't talk about that is only possible with option strict of) and therefore something extra to remind or to check for if you are not used to it. Dim Str$ is the exception. Dim str as String Dim whatever as MyClass Dim .. as etc etc. Therefore in my idea Dim str as String tells directer to people (what program language they are used) what you mean. However feel free to do it your way, it is only my opinion.

discouraged. One reason is that there isn't a type declaration character for all data types, and it makes it difficult for other developers that aren't used to read code you have written using type declaration characters. Obviously it is a matter of preference, but personally I find code with type declaration characters hideous and downright difficult to read, but hey that's just my opinion. :-) Another issue you touch upon Cor, is that of using Hungarian Notation (VB prefixes such as str, int etc.), which is also discouraged.

Check out my last response to Cor's comments, it gives my opinion on this about as well as I can explain it. Thanks for your comments though. btw, while I freely use the suffixs when they are available for a particular data type, I don't tack them onto the numeric variables (such as "n%") in the body of my procedures, I just use the $ in the body, to remind me which ones are strings.

I see what you been there -- your way is (a) consistent with the way other objects work in vb, and (b) clear to others that don't know vb. I would point out re (b), that no one is going to be studying my programs that is (a) not me, or (b) doesn't already know vb. I don't think vb beginners are going to be using my programs to learn on! Regarding (a), there is a certain consistency to my method, because other common types (though not all) also can use a suffux, such as % for integer.Remember that its nice to have a reminder of the type of variable in the body of the procedure. Lots of people use the prefix system -- eg, strName -- to remind them. But "Name$" is to me a lot better than "strName". With the latter, you are constantly seeing first the "str" instead of the actual name of the variable, and it gets old. The other way, you can just tack on $ at the end and know its a string. Also, I often use one-letter variable names (such a "s" for a string I might need, "n" for a number type, etc.) If I don't have a reminder of which ones are strings, I can get confused. In such cases, "s$" is makes a lot more sense than "strS" Anyway, as you say, its all what you prefer and/or what you are used to. I just think my system is as good or better than the "strName" approach I see in books everywhere, and I get sick of that system and can't understand why more people don't at least mention mine. By the way, I notice that some very good authors do actually use my system, such as the author of the book on Windows API for Visual Basic. Check it out.

You don't see those solution almost no more (expect there where really needed and that is seldom). About what you wrote, you are right that not everybody is using the same methods to declare. Although I try to avoid forever global or in top of a method placed names. Which makes it me easy to see what the format of something is, but even that is not standard.
