 | Re: Table listing It sounds like you're not updating "createConnection" with the value selected on the previous form. You probably need to upload a project so we can take a look at it. The problem you're describing is occuring outside the scope of the code you posted. |
| | You typically just put a parent in the constructor: [code=csharp] public IOAnalog() { } public IOAnalog(Sensor Parent, IOAnalogType AnalogType) : this() { this._parent = Parent; this._IOType = AnalogType; } [/code] Will this not work? |

| | [b]I have already answered your question.[/b] Please see [url]http://www.daniweb.com/forums/thread209172.html[/url] An "Image" is stored on disk in the native "image format" which is represented with "binary". "Binary" and "Image Format" are the same thing. However a [icode]byte[][/icode] array and [icode]Image[/icode] are different in managed code. Go back to the original thread …  |

| | This is really an SQL question. What you would do is: [code=sql] Declare @Name varchar(1), @City varchar(1), @State varchar(1) Set @Name = 'a' Set @City = 'b' Set @State = 'c' Insert Into Customer (Name, City, State) Select @Name, @City, @State Where NOT EXISTS ( Select * From Customer (NOLOCK) … |
| | [code=bash] sk@svn:~/test$ ls -al *.sql | awk '{ print $8 }' file1.sql file2.sql file3.sql [/code] If you're reading this from a file you can change it to: [code=bash] sk@svn:~/test$ ls -al *.sql >> someFile sk@svn:~/test$ awk '{ print $8 }' someFile file1.sql file2.sql file3.sql [/code] |
| | Not necessarily. You could do this: [code=sql] Declare @CityId int, @CategoryId int Set @CityId = (select city_id from city_master where city_name= 'abc') Set @CategoryId = (select city_id from city_master where city_name='123') Insert into wines_available(name, address, city_id, category_id) values (@name, @address, @cityid, @categoryid) [/code] |
| | You need to format the string before you populate the ListView. To get the thousand separator without decimals use: [code=c#] private void button2_Click(object sender, EventArgs e) { int i1 = 5555; Console.WriteLine(i1.ToString("N0", System.Globalization.CultureInfo.InvariantCulture)); } [/code] |
| | It is almost certainly not because of the number of users. As you indicated SQL Server can handle hundreds of users with no problem. What you should do is run the SQL Server Profiler and watch the database activity. Also check the windows event log and SQL Server error log … |

| | What is "relational algebra"? Also what approaches have you tried? Post your queries here and what problems you are having with them and we will work from there. |
| | Yeah ... that happens if you call that property before the session initializes. That happened to me -- I think in your Global.asax if you call it in your Application_Start it will throw that error. Check the call stack and report back where it is being called from. |
