i agree with the pallini's solution and also david gave a good description. string literals r located in a const part of memory which is not writable. this is why arrays don't cause crash. they're located in heap or stack based on whether u allocate them or use local variables which r both writable parts of memory. there's an API function to determine whether a block of memory or a string is const named AfxIsValidAddress. it may also test whether the block is writable. but if i were u, i would use _strdup anyway, and would pass the arg as const for the caller to make sure that the original version of the passed string is not altered.

Ok and why do you think I should use vi, gvim, or BBEdit? What are the special features? Do they provide code completion or sth. like the Intelli-Sense in VS? C# and other languages[^]

A well deserved 5 for answering your own question. Deja View - the feeling that you've seen this post before.

Thank you very much!:-D

:laugh: Yeah and Google is culpable as well since they provide a perfectly usable Search Engine.

Thank you very much.

I have to try 3. I think. I hoped i don't have to use a timer :(

I never understand why people save their connection strings in web.config... how unsecure is that? This is how I avoid your problem: 1) In global.asax I have a function like this: Sub Application_Start(ByVal sender As Object, ByVal e As EventArgs) Select Case Server.MachineName.ToLower Case "aaaaa" ' local Application("ServerName") = "local" Case "bbbbb" ' laptop Application("ServerName") = "laptop" Case Else ' ' live Application("ServerName") = "live" End Select End Sub You will need to find out, if you don't know already, your local machines name. User Server.MachineName in any aspx page to find out if you need to. 2) I then make a publicly available function such this: Public Class myFunctions Public Function dbConnection(ByVal ServerName As String) As String Select Case ServerName Case "live" Return "data source=xxxxx;initial catalog=xxxxx;uid=xxxxx;pwd=xxxxx" Case "local" Return "data source=yyyyy;initial catalog=yyyyy;uid=yyyyyy;pwd=yyyyyy" Case "laptop" Return "data source=zzzzzz;initial catalog=zzzzz;uid=zzzzz;pwd=zzzzz" End Select End Function End Class 3) Then I can use the same code throught my app to connect to the database on whateve computer I am running on: Dim myFunction As New myFunctions Dim objConn As New SqlClient.SqlConnection objConn.ConnectionString = myFunction.dbConnection(Application("ServerName")) Works a treat! -- modified at 15:11 Tuesday 28th August, 2007 Of course, you don't acually need to use the Application object at all, but could call the function directly with objConn.ConnectionString = myFunction.dbConnection(Server.MachineName) if you replaced the Select..Case in the dbConnection function with the amchine names there instead of the aliases I created. But there was a reason I did it this way when I first came up with it - just can't remember what it was now! - and I have always done it the same way since! Fred

and yes i forgot to mention one thing, this type of error usually occurs when you are going to another class/form, like the way you were doing myform.show() and in your myform load event you had something n there you get some error :)

OK thank you. I have to do it for work :D

Thank you very much everyone :D

This might be a little vague, but better than nothing I hope. One way to rotate about an arbitrary axis (there are others): - find the unique point on the axis such that a line from that point to the origin is perpendicular to the axis - let's suppose the point is 1,2,3 -translate that point to the origin - Translation(-1,-2,-3) -do the rotation -undo the translation - Translation(1,2,3) Hope that helps a bit

you could use FileStream to copy the file into a MemoryStream, and later use StreamReader from MemoryStream to parse it. FileStream fs = new FileStream("text.txt", FileMode.Open, FileAccess.Read); MemoryStream ms = new MemoryStream(); byte[] buf = new byte[4096]; int bytes = 0; while((bytes = fs.Read(buf, 0, 4096)) > 0) { ms.Write(buf, 0, bytes); } fs.close(); StreamReader sr = new StreamReader(ms); string x = sr.ReadLine(); My second computer is your linux box.

Ok i'll try it, but would you post an example how to integrate this method in my line? That's the biggest problem i have :-O

Perhaps but when a question is posed so vague as to say where is my null reference exception i think any little bit of help will help. Now you are correct in that when I said d.Month I was wrong. Sometimes I say the stupidest things. Of course, that could also fall into the category of someone designing an OO language that doesn't fully support nulls until the third release. File Not Found

I found a solution select gen_id(, 0) from rdb\$database @cleako Could you post an small example? I'm new to programming with databases. Thank you

Thank you, it works for me :D For everyone else, if you use this tool on FB Embedded and you are promted for username and password but you never used it because you don't had to, use sysadmin / masterkey. That's the standard.

Ah, thanks, now i understand :D

Thank you, i'll have a look at both!:-D
