Hi everybody...
I have some problems related to a querystring issue.
I`m calling an ASPX page, with some querystring parameters, from a JavaScript function, through the window.open method.
The way this URL is configured and called in the javascript function is the following: EnviarMapaEmail.aspx?type=addPt&x=-46.644203856241546&y=-23.571182563934798&st=Av.%20Paulista&nb=10&city=S%C3O%20PAULO&uf=SP&POI=
And in the ASPX page, the Request.QueryString comes this way:
type=addPt&x=-46.644203856241546&y=-23.571182563934798&st=Av.+Paulista&nb=10&city=SO+PAULO&uf=SP&POI=
The problem is: the original city name (city parameter) is 'SÃO PAULO' and it`s encoded in the URL (thought the escape() javascript function) as 'S%C3O%20PAULO', but my ASPX page only recognize'SO+PAULO' and it goes back through the Request.QueryString as 'SO PAULO'.
What`s the problem in encoding especial chars?
Any hint would be very appreciated... :]
See you!

AFAIK, the settings that decide how the escaped codes in the request are decoded are:
:: The content-type setting in the html header, which probably comes from:
:: The content-type meta tag in the sending page.
:: The RequestEncoding setting in the web.config file.
Also, the escape function might not take into account the selected encoding for the page. Try the newer encodeURIComponent function instead.

single minded; short sighted; long gone;

hey guffa...
thank you, it worked.
both pages are .aspx, so, presumably, they`re using the same encoding type.
but your hint about the encodeURIComponent function worked fine, both on IE and FF.

Assume that you are deploying to remote server. Copy all aspx files, and config files. Copy bin folder also which contains all dll's. SQL DB can be deployed as a .SQL file.

well.. i guess there aint any splash screen functionality inbuilt into ASP.net, though u can set it running using some javacript tweaks..
create an initial page and add the splash screen content in it.. use the setinterval() javascript function to redirect to another page after a set time interval.
or u may even use AJAX so that the content is displayed on the same page..
i hope u get it

I read a boolean value from a table with this:
Public SQLconn As New SqlConnection(ConfigurationManager.ConnectionStrings("TestConnectionString").ToString())
Sub Page_Load(ByVal Sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
SQLconn.Open()
Dim SelectCmd1 As New SqlCommand("SELECT value1 from table1", SQLconn)
SelectCmd1.CommandType = CommandType.StoredProcedure
Dim result1 As Boolean
Dim myDataReader As SqlDataReader
myDataReader = SelectCmd.ExecuteReader()
myDataReader.Read()
result = myDataReader1.GetBoolean(0)
SQLconn.Close()
ChangeButton1(result1)
End Sub
Is it possible to read values from two tables or more with the same method and if not what can I do?
I tried this:
Dim SelectCmd1 As New SqlCommand("SELECT value1.table1, value2.table2 FROM table1, table2", SQLconn)
SelectCmd1.CommandType = CommandType.StoredProcedure
Dim result1 As Boolean
[b]Dim result2 As Boolean[/b]
Dim myDataReader As SqlDataReader
myDataReader = SelectCmd1.ExecuteReader()
myDataReader.Read()
result1 = myDataReader.GetBoolean(0)
[b]result2 = myDataReader.GetBoolean(1)[/b]
SQLconn.Close()
ChangeButton(result1, result2)
End Sub
Could this work????
Any help will be much appreciated!!!

If you are using .net 2.0 then ado supports MARS (multiple result sets). Here is some sample code from MS help:
' Assumes that connection is a valid SqlConnection object.
Dim command As SqlCommand = New SqlCommand( _
"SELECT CategoryID, CategoryName FROM dbo.Categories;" & _
"SELECT EmployeeID, LastName FROM dbo.Employees", connection)
connection.Open()
Dim reader As SqlDataReader = command.ExecuteReader()
Dim nextResult As Boolean = True
Do Until Not nextResult
Console.WriteLine(vbTab & reader.GetName(0) & vbTab & reader.GetName(1))
Do While reader.Read()
Console.WriteLine(vbTab & reader.GetInt32(0) & vbTab & reader.GetString(1))
Loop
nextResult = reader.NextResult()
Loop
reader.Close()
connection.Close()
Hope that helps.

hi,
This will not work.
The qurey provided by you will return table1.rowcount * table2.rowcount number of recored.
Can you please specify why you want data from both table and what is the actual requirment?
Thanks and Regards,

@kubben I will check it
@Chetan
I have a hardware device that is connected to a sql database. I also have 7 switches connected to this device. So every time I toggle the boolean value(press button event in asp.net page) I turn on or off the corresponding switch. I use Page_load to initialize the button controls. Every switch is connected to a table with on one record that I update from the page.
The whole code for "one" button looks like this:
Public SQLconn As New SqlConnection(ConfigurationManager.ConnectionStrings("TestConnectionString").ToString())
Sub Page_Load(ByVal Sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
SQLconn.Open()
Dim SelectCmd1 As New SqlCommand("SELECT rawvalue FROM switch1", SQLconn)
SelectCmd1.CommandType = CommandType.StoredProcedure
Dim result1 As Boolean
Dim myDataReader1 As SqlDataReader
myDataReader1 = SelectCmd1.ExecuteReader()
myDataReader1.Read()
result1 = myDataReader1.GetBoolean(0)
SQLconn.Close()
ChangeButton1(result1)
End Sub
Sub ChangeButton1(ByVal Status As Boolean)
If Status Then
Label1.Text = "ON"
OnOff1.Style.Value = "background-image: url(../ImgContr/1.png);"
Else
Label1.Text = "OFF"
OnOff1.Style.Value = "background-image: url(../ImgContr/2.png);"
End If
End Sub
Sub OnOff_Click1(ByVal Sender As Object, ByVal e As System.EventArgs)
Dim updateCMD As SqlCommand
Dim query As String
If Label1.Text = "ON" Then
query = "UPDATE [switch1] SET [rawvalue] = 'False' WHERE [device] = 'channel1'"
ChangeButton1(0)
Else
query = "UPDATE [switch1] SET [rawvalue] = 'True' WHERE [device] = 'channel1'"
ChangeButton1(1)
End If
updateCMD = New SqlCommand(query, SQLconn)
updateCMD.CommandType = CommandType.Text
SQLconn.Open()
updateCMD.ExecuteNonQuery()
SQLconn.Close()
End Sub
It works for 7 switches too but I have to write every SUB 7 times.
And the initialization looks like this:
Sub Page_Load(ByVal Sender As Object, ByVal e As System.EventArgs) Handles MyBase.Load
SQLconn.Open()
Dim SelectCmd1 As New SqlCommand("prodiakoptis1", SQLconn)
SelectCmd1.CommandType = CommandType.StoredProcedure
Dim result1 As Boolean
Dim myDataReader1 As SqlDataReader
myDataReader1 = SelectCmd1.ExecuteReader()
myDataReader1.Read()
result1 = myDataReader1.GetBoolean(0)
SQLconn.Close()
SQLconn.Open()
Dim SelectCmd2 As New SqlCommand("prodiakoptis2", SQLconn)
SelectCmd2.CommandType = CommandType.StoredProcedure
Dim result2 As Boolean
Dim myDataReader2 As SqlDataReader
myDataReader2 = SelectCmd2.ExecuteReader()
myDataReader2.Read()
result2 = myDataReader2.GetBoolean(0)
SQLconn.Close()

Hi,
First of all you dont need to open and close the connection everytime you are calling new stored procedure.
You can create only one stored procedure which will return all the values u need in the form of output parameters. Remeber this is advisable only if your number of switches is not going to change in future.
You must be familier with how to create and execute stored procedure with output parameters.
Thanks and Regards,

I actualy created a SP to retrieve the data from the tables.
ALTER PROCEDURE dbo.switch1
/*
(
@parameter1 int = 5,
@parameter2 datatype OUTPUT
)
*/
AS
SELECT [rawvalue] FROM [switch1]
/* SET NOCOUNT ON */
RETURN
I have one SP for every table.
Even if I create a SP what I don't know is how to read all this values with the datareader.

Hi,
Is your current procedure is returning more than one rows/values?
Thanks and Regards,

No the table has only one row and the procedure returns only one boolean value.
Thanks

Hi,
Then it is not necessary to use reader.
You can create a procedure that will return the values u need and then you those values as per your requirement.
In the procedure you can write selecte statements for all the tables and the assing the values to the output parameters.
By this way you will not need to write the same code again and again and only one procedure will do all your work.
Thanks and Regards,

Hi,
I hope the following solution will help you.
You create a common event handler for the command event of all your switchbuttons.
public void bttns_command(object sender, CommandEventargs e)
{
if(e.CommandName == "Switch1")
{
//do work related to switch1;
if(Label1.Text == "ON")
{
query = "Update ..........."
ChangeButton("Switch1",0);
}
else
{
query = "update............."
ChangeButton*("Switch1",1);
}
updateCMD = New SqlCommand(query, SQLconn)
updateCMD.CommandType = CommandType.Text
SQLconn.Open()
updateCMD.ExecuteNonQuery()
SQLconn.Close()
}
else if(e.CommandName == "Switch2")
{
if(Label2.Text == "ON")
{
query = "Update ..........."
ChangeButton("Switch2",0);
}
else
{
query = "update............."
ChangeButton*("Switch2",1);
}
updateCMD = New SqlCommand(query, SQLconn)
updateCMD.CommandType = CommandType.Text
SQLconn.Open()
updateCMD.ExecuteNonQuery()
SQLconn.Close()
}
else if(e.CommandName == "Switch3")
{
if(Label3.Text == "ON")
{
query = "Update ..........."
ChangeButton("Switch3",0);
}
else
{
query = "update............."
ChangeButton*("Switch3",1);
}
updateCMD = New SqlCommand(query, SQLconn)
updateCMD.CommandType = CommandType.Text
SQLconn.Open()
updateCMD.ExecuteNonQuery()
SQLconn.Close()
}
}
The html for your buttons should look like following.
<asp:Button id="bttnSwitch1" Runat="server" CommandName = "Switch1"
OnCommand="bttns_command"></asp:Button>
<asp:Button id="bttnSwitch2" Runat="server" CommandName = "Switch2"
OnCommand="bttns_command"></asp:Button>
<asp:Button id="bttnSwitch3" Runat="server" CommandName = "Switch3"
OnCommand="bttns_command"></asp:Button>
Now you ChangButton function shuld look like following:
private void ChangeButton(string switchname, bool status)
{
if(switchname == "Switch1")
{
if(status)
{
Label1.Text = "ON";
OnOff1.Style.Value = "background-image: url(../ImgContr/1.png);"
}
else
{
Label1.Text = "OFF"
OnOff1.Style.Value = "background-image: url(../ImgContr/2.png);"
}
}
else if(switchname == "Switch2")
{
if(status)
{
Label2.Text = "ON";
OnOff2.Style.Value = "background-image: url(../ImgContr/1.png);"
}
else
{
Label2.Text = "OFF"
OnOff2.Style.Value = "background-image: url(../ImgContr/2.png);"
}
}
else if(switchname == "Switch3")
{
if(status)
{
Label3.Text = "ON";
OnOff3.Style.Value = "background-image: url(../ImgContr/1.png);"
}
else
{
Label3.Text = "OFF"
OnOff3.Style.Value = "background-image: url(../ImgContr/2.png);"
}
}
}
I hope this will help you.
Thanks and Regards,
