Hi Ive created an application using c# vs2008 and sql server 2005
on my pc everything works fine, but when i release it onto a server it has trouble connecting to the database.
Im using Linq - ive created a DataLinq project, a DataAccess project and a BusinessLogic project...
For the Linq project i simply added a dbml file, dragged all the necessary tables across and voila...
If I do a search for 'connectionString' in the DataLinq project - it appears in a number of places with the actual value hard coded - its in:
app.config
bin\Debug\DataLinq.dll.config
DBLinq.dbml
Settings.Designer.cs
Settings.settings
I would expect it in the app.config file - am I expected to change it in all the locations before release or am i doing something wrong?
Cheers,
Chas

Just app.config will be enough!
bin\Debug\DataLinq.dll.config is a copy of app.config made by VS on build success.
application settings are written to the app.config as well (in settings you can choose application or user)

You can the jpg file, the top region of the topmost panel is covered with toolstrip.

Hi,
Is this just a problem with the way you have constructed the form in the designer? With docking controls you really need to start at the outside and work in towards the middle.
1) Form
2) menu strip
3) tool strip
4) split container.
Alan.

When this sort of thing happens, simply right-click on the control that is partly hidden and from the context menu that appears click Bring To Front.
Problem Solved!

I want to remove the http response header using regular expression
for example the following is the response i get
-----------------------------------------------
HTTP/1.1 200 OK
Date: Fri, 07 Aug 2009 18:10:29 GMT
Server: Apache/2.0.63 (Unix) mod_ssl/2.0.63 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimited/1.4 FrontPage/5.0.2.2635 PHP/5.2.8
X-Powered-By: PHP/5.2.8
Content-Length: 140
Connection: close
Content-Type: text/html
A Word a Moment
Word : somber
Pron : sombu(r)
Meaning :
1. Lacking brightness or colour; dull
Example : (empty)
---------------------------------------------------
and i need only the text after "A word a moment"
so i thought of this code which is not as expected
string outs = Regex.Replace(cont, "^.*\r\n\r\n", "", RegexOptions.Multiline);
what could be the pattern to remove the http response header so that i can just use the actual response?

I think it would be easier for you if you don't use a regexp. You can simply drop all the header, directly when reading from the socket's stream.
If you can only have the full text in a string (for example if you are using a third-party library and cannot modify the code which reads from the socket), then you can parse it and find the beginning of the text you need.

sure. but i thought i can include the knowledge of using regex with win32. actually i already have a program written in win32 api which is working well. in that i used strpos to find the two \r\n\r\n to find the end of the response header. coding in win32 api to accomplish my need gets tedious so i am writing the same program in c#. instead of the old way i thought of trying new. anyway do you know how to read the response body using any of System.Net.Sockets ? ... and the program is here ... http://vikku.info/wordreminder/[^]

Ok I see. Well, if you want to use regexps, the easiest way I can think of is something like:
string HttpText = "HTTP/1.1 200 OK\r\nDate: Fri, 07 Aug 2009 18:10:29 GMT\r\nServer: Apache
/2.0.63 (Unix) mod_ssl/2.0.63 OpenSSL/0.9.8e-fips-rhel5 mod_auth_passthrough/2.1 mod_bwlimi
ted/1.4 FrontPage/5.0.2.2635 PHP/5.2.8\r\nX-Powered-By: PHP/5.2.8\r\nContent-Length: 140\r\
nConnection: close\r\nContent-Type: text/html\r\n\r\nA Word a Moment\r\nWord : somber\r\n\r
\nPron : sombu(r)\r\n\r\nMeaning :\r\n1. Lacking brightness or colour; dull\r\n\r\nExample
: (empty)\r\n\r\n";
Regex MyRegex = new Regex("\r\n\r\n");
String[] MyStrings = MyRegex.Split(HttpText, 2);
if (MyStrings.Length != 2)
{
throw new ApplicationException("Error parsing HTTP response!");
}
Console.WriteLine("Header:");
Console.WriteLine("-------");
Console.WriteLine(MyStrings[0]);
Console.WriteLine("Body:");
Console.WriteLine("-------");
Console.WriteLine(MyStrings[1]);
Console.WriteLine("-------");
But it doesn't make much sense to use the Regex object here, since the pattern separating header from body is a fixed string ("\r\n\r\n"), so the same can be done using String.Split(), which is simpler and more performing.
If you want to use Regex.Replace(), like in your example, then you will have to limit the number of matches to replace to one, otherwise ALL matches will be replaced with the empty string! See the docs here[^].
Regarding how to read data from a socket, if you check the docs for objects in System.Net.Sockets, like TcpClient[^], you'll see they expose methods to obtain a NetworkStream[^], which you can use to read data.

Excellent. thank you for your needful reply. the tcpclient will help for now and also i will tinger with the others. i had a quick view of your links and i have to spend more time on that.

Hello,
I am creating a GUID and then using that ID inside a SQL statement. I get an error saying that incorrect syntax near '-' , and I believe its referring to the dashes that are created with the GUID. So i was going to split up the GUID and just make it a string of characters. Can anyone help me do this? BElow is a little bit of code to show how I'm using it. Thanks for your help!
SqlConnection sqlConn = new SqlConnection("Data Source=localhost;Initial Catalog=Cost_Model;Integrated Security=True");
sqlConn.Open();
System.Guid UID = System.Guid.NewGuid();
Int16 SCENARIOID = 1;
SqlCommand sqlComm1 = new SqlCommand(
"INSERT INTO web_far15 select " + UID + ", * from fn_far15(" + SCENARIOID + ")",
sqlConn);
SqlDataReader r = sqlComm1.ExecuteReader(CommandBehavior.CloseConnection);
Session["TableName"] = "web_far15";
Session["SessionID"] = UID;
r.Close();
Thanks again for your help!

Ummm... what? If you provide the GUID as a string SQL Server will parse it.
SELECT * FROM table WHERE ID='blah-blah-blah...'
I don't know whether or not other databases will.
But you'd have an even easier time using a parameterized statement.
|
|
|
|
|
All I did to get the GUID was
System.Guid UID = System.Guid.NewGuid();<code> which created the code.<br />
<br />
When I try to pass the GUID directly it does not allow it, I get the '-' error explained above. Its also not letting me typecast it to a string.
|
|
|
|
|
Parse it with what? Why do you need to parse it?
System.Guid has a constructor that will do it. SQL Server will do it. But you shouldn't need to do it at all.
|
|
|
|
|
I believe I need to parse it so I can take out the dashes. When I run the code, I get the error "Incorrect syntax near '-'." and it breaks at SqlDataReader r = sqlComm1.ExecuteReader(CommandBehavior.CloseConnection);
So when I read that, that sounds like I need to take out the dashes. Am I incorrect?

0) Put the GUID in apostrophes if you insist on writing poor SQL.
1) Use a parameterized query to write good SQL.

I am trying to retrieve the contents of multiple textboxes using a for loop as follows:
for (int x = 1; x < 6; x++)
{
string vDate = "txtDate" + x + ".Text"; // vDate = txtDate1.Text on 1st iteration
string vFund = "txtFund" + x + ".Text";
string outDate = vDate; // this should = txtDate1.Text on 1st iteration
string outFund = vFund;
}
When I run the code outDate = txtDate1.Text and outFund = txtFund1.Text. How do I set variable to equal the text contents of the textbox? Any help would be appreciated.
Thanks

Instead of just outputting C# code in text file better leverage C# ability to write code that in turn output code for you. You can then execute that outputted code. I am taking about code dom feature of C#
|
|
|
|
|
private void DoSomethingWithATextBox(TextBox textBox){
}
...
DoSomethingWithATextBox(txtDate1);
DoSomethingWithATextBox(txtDate2);
DoSomethingWithATextBox(txtDate3);
DoSomethingWithATextBox(txtDate4);
DoSomethingWithATextBox(txtDate5);
DoSomethingWithATextBox(txtDate6);
Much easier than doing the loop method which will be dependent on proper code generation. Also, the loop method is available in ASP.NET but I still don't like it. My method is much cleaner and easier to maintain.

Hi,
two easy ways:
1.
use a List<TextBox> textboxes to which you add the textboxes of interest, then a simple foreach(TextBox tb in textboxes) will do the job.
2.
if you want to enumerate ALL the textboxes of a Form, and they all are at the top level of that form, you could do:
foreach (Control c in this.Controls) {
TextBox tb=c as TextBox;
if (tb!=null) { ... do something to tb ... }
}

Anyone got a good idea as to how I can monitor the number of times my application is actively running on various PCs across a network. I want to licence my product based on concurrent usage, therefore allow it to be installed on any number of PCs on a newtwork, but perhaps only allow ten instances to be running/accessed at the same time. My app does not use a database, therefore preventing me monitoring the number of logged in connections. I suppose I could place a file in a shared location, but would rely on the application have the rights to update the file, and not making it obvious to users that this file monitors the number of active instances. Neither can I guarentee the network admin will allow a socket server type application to be installed allowing each program to connect as a client.
The reason for this query is that I'm not too keen on having to enforce users or company to register a product key based on the PC's MAC address (or something simplar) for each PC it's installed on, but if this is the best approach, then this is the approach I'll take.
Any ideas on a possible way forward?? 
Andy
