Go through this site. You can add and encrypt the connection strings:

The ConfigurationManager class has functionality that would allow you to load the configuration file, target the section that has the connection string (typically, ConnectionStrings or AppSettings), modify the connectionstring and then save back. You will need to import System.Configuration namespace.

I need to validate a URL. At present, I'm using a regular expression, (http(s)?://((w{3})+\.)+([\w-]+\.)+(\w{2,4})+(/[\w- ./?%&=]*)?)|((w{3})+\.)+([\w-]+\.)+(\w{2,4})+(/[\w- ./?%&=]*)?
This Validation expression will work fine only when the URL is in full, like for eg: http://www.abc.com.
There are cases where the url can't have www. In that case, this expression will throw error. For eg: http://forums.microsoft.com. So how to modify the above url? Can anybody please provide any help on this?
Thanks

Just break it into scheme (protocol) and host.
Scheme is everything before ://
Host is everything after :// and before first / (or \)
Path, file, arguements is everything from first / on.
e.g. http://microsoft.com:80/path/file?arg1=1&arg2=2
scheme = "http"
host = "microsoft.com:80" (actually host:port)
path = "/path/" (some leave off trailing /)
file = "file"
args = "arg1=1&arg2=2"
...cmk
The idea that I can be presented with a problem, set out to logically solve it with the tools at hand, and wind up with a program that could not be legally used because someone else followed the same logical steps some years ago and filed for a patent on it is horrifying.

I want to upload an image to sqlserver, i use fileupload control and upload the image.
But when I retrieve it to gideview it appears as a text: System.Byte[]
How can i solve this problem..
thanks
|

I always say that it is better to store the file location of the image in your database rather then the actual image. This means that your database doesnt become bloated and at the same time you can retrieve the image in almost the same way.
|
|
|
|
|
Could you explaine more what you mean.
Im using the following code to upload the file is there any mistake.
Dim imageBytes(FileUpload1.PostedFile.InputStream.Length) As Byte
FileUpload1.PostedFile.InputStream.Read(imageBytes, 0, imageBytes.Length)
myCommand.Parameters.AddWithValue("@ImageData", imageBytes)
thanks

Have u Tried this...
FileUpload1.FileBytes;

How many versions are there?
Ramana. G.V wrote: anybody please tell me which windows version is better for .Net developers.
I think most people in this forum would recommend anything over Vista.
|
|
|
|
|
These are the versions
1) Vista Home Basic
2) Vista Home Premium
3) Business
4) Ultimate
which version is better?

I'm not sure that it makes a huge amount of difference which version you choose. I have worked on a variety of OPs and found that VWD or Visual Studio performs fine on most.
If you have a slow machine obviously this will cause a problem.

I am using Vista Ultimate and it is okay. Not great, not bad, just okay ( running it on a machine that is plenty able to handle it  ). It all depends on how powerful of a machine you have.

Try as below:
Response.Clear();
Response.AddHeader("content-disposition", "attachment;
filename=FileName.xls");
Response.ContentType = "application/vnd.xls";
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite =
new HtmlTextWriter(stringWrite);
GridView1.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();

Hi am a beginner in dotnet .Am creating a web application in asp vb.net .First i will tell what i want to accomplish
First i have a page when the user logins in to that site the page will display what all the tasks allocated to him in a datagrid
The datagrid has a check box for each of the rows being displayed.
and outside the datagrid there is a send button.When the user clicks the check box and then clicks the send button these datas must get displayed in the another datagrid which is present in another page.
What i have done in back end for this is:
When i check the check box and click the save button all the details will get inserted into the temp table and inside the temp table i have set a flag when the user checks the check box the flag will turn into "y" and the another datagrid which i want to display all the records will choose only the records where the flag is set to "y"
and the codes for it is as follows:
the SP on button click is as follows:
CREATE PROCEDURE USP_VIEW_TASK_UPDATE
(
@TASK_ID VARCHAR(5),
@TASK_ALLOC_DATE DATETIME,
@PROJ_ID VARCHAR(15),
@SUBMOD_ID VARCHAR(15),
@ACTIVITY VARCHAR(15),
@TASK_CREATE_BY VARCHAR(15),
@TASK_DETAILS VARCHAR(100),
@ASSOC_ID VARCHAR(15),
@SEND CHAR(1)
)
AS
BEGIN
CREATE TABLE UST_VIEW_TASK_TEMP
(
TASK_ID VARCHAR(5),
TASK_ALLOC_DATE DATETIME,
PROJ_ID VARCHAR(15),
SUBMOD_ID VARCHAR(15),
ACTIVITY VARCHAR(20),
TASK_CREATE_BY VARCHAR(15),
TASK_DETAILS VARCHAR(100),
SEND CHAR(1)
)
INSERT INTO UST_VIEW_TASK_TEMP VALUES
(
@TASK_ID,
@TASK_ALLOC_DATE,
@PROJ_ID,
@SUBMOD_ID,
@ACTIVITY,
@TASK_CREATE_BY,
@TASK_DETAILS,
@SEND
)
SELECT
ALLO.TASK_ID,
ALLO.TASK_ALLOC_DATE,
HIST.PROJ_ID,
HIST.SUBMOD_ID,
HIST.ACTIVITY,
HIST.TASK_CREATE_BY,
ALLO.TASK_DETAILS,
'N'
FROM
UST_TASK_ALLOCATION ALLO,
UST_TASK_HISTORY HIST
WHERE
ASSOC_ID =@ASSOC_ID
AND convert(varchar,ALLO.TASK_ALLOC_DATE,112) =convert(varchar,getdate(),112)
AND HIST.TASK_ID=ALLO.TASK_ID
AND ALLO.TASK_ID=@TASK_ID
UPDATE UST_VIEW_TASK_TEMP SET SEND='Y'
WHERE
ASSOC_ID =@ASSOC_ID
AND HIST.TASK_ID=ALLO.TASK_ID
AND ALLO.TASK_ID=@TASK_ID
END
and the front end which i havedone on selecting a check box and the button click is:
Dim bsl As New BSL

End If
Next
Dim ds As DataSet
dgUserhometask.DataSource = ds.Tables(0)
dgUserhometask.DataBind()
End Sub
UserTaskStatus function is as :

End With
Catch ex As Exception

in the second page:
the sp which will be called after button click is:
create procedure USP_USER_VIEW_TASK
(
@ASSOC_ID VARCHAR(30),
@TASK_ID VARCHAR(5)
)
as
begin
SELECT * FROM UST_VIEW_TASK_TEMP
WHERE
SEND='Y'
AND ASSOC_ID =@ASSOC_ID
AND convert(varchar,TASK_ALLOC_DATE,112) =convert(varchar,getdate(),112)
AND TASK_ID=@TASK_ID
END
and the front end coding is for it is:
Dim Connstr As String = "myconnectionstring"
Dim bsl As New BSL
Dim AllocatedDate As String
Dim taskid As String
Dim AssocID As String
AssocID = Convert.ToString(Session.Item("Username"))
Dim dsViewHomeTask As New DataSet
dsViewHomeTask = bsl.ViewHomeTaskStatus(Connstr, AllocatedDate, taskid, AssocID)---->(View Home Task Status is a function which will call the SP)
If (dsViewHomeTask.Tables(0).Rows.Count > 0) Then
dgUpdtasksave.DataSource = dsViewHomeTask.Tables(0)
dgUpdtasksave.DataBind()
lblError.visible = False
Else
lblError.visible = True
dgUpdtasksend.ShowHeader = False
End If
View Home TaskStatus is a sfollows:
Public Function ViewHomeTaskStatus(ByVal Connstr As String, ByVal AllocatedDate As String, ByVal taskid As String, ByVal AssocID As String) As DataSet

.AddInParameter("@ASSOC_ID", SqlDbType.VarChar, AssocID, 3)
dsViewTask = .GetDataSet("USP_USER_VIEW_TASK")
Return dsViewTask
End With
Catch ex As Exception
End Try
End Function
But when i click the check box and then the save button
its throwing an error "object reference not set to an instance of the object" in the place
If (dsViewHomeTask.Tables(0).Rows.Count > 0) Then
dgUpdtasksave.DataSource = dsViewHomeTask.Tables(0)
in the second page
The second page will show a message if there is no records to display when the user doesnt click the button even that it is not showing its throwing the same error for it .
Can anyone help me in sorting this out

Don't just catch the exception and ignore it. If there is a problem, you won't get any notification about it, and you have no information about what it could be.
Comment out the Try..Catch code until you have got the code working. After that you can reintroduce it, with the addition of actually handling the exception in some way, e.g. displaying a message to the user.
Despite everything, the person most likely to be fooling you next is yourself.

Hi thank You,
after u mentioned it i wrote in catch
System.Diagnostics.Trace.WriteLine("[] Exception " & ex.Message)
after that i debugged it its throwing an error like this
"Object reference not set to an instance of an object."
