Hi,
I am hosting on a remote host somewhere in US.
I have a folder with sub folders inside it. The folder name is : member
I want when creating a new member to copy the folder and all its subfolder to a new folder called xxx
both member folders and xxx folder are in ~/images/
how can I do this?
Thanks,
|
|
|
|
|
I tried this but not working:
string path = "~/images/" + "TTTTTTT";
DirectoryInfo directoryInfo = new DirectoryInfo(Server.MapPath(path));
if (!directoryInfo.Exists)
{ directoryInfo.Create(); }
I am not getting any error but directory is not getting created either!
|

Can you have a logger to log the 'path' like this
logger.Debug(path) in both if and else routes?

I decided to use Oracle 11.g for a new website job I sold that sells chips.
A small project to experiment with Oracle, and see how good it works, what's up with it, it is better than SQL Server 2008
I figured out most of the stuff, got the databases, tablespaces, permissions going.
Having trouble understanding parameters, and using the OracleDataReader in asp.net, and I'm not quite sure if I used the OracleConnection and OracleCommand correctly.
1. Specified cast is not valid. I know what it means, but I'm trying to figure out a different way of expressing it below.
p_Count = oReader.GetInt32(0) 'TheCount
2. Using the Parameters, I think Oracle doesn't like the @ char in the parameter name.
I want to say "SELECT COUNT(*) FROM WWW.RC$_PRODUCTINDEX WHERE MANUFACTURE=@MANUFACTURE"
But I get a error - ORA-00936: missing expression
Anyways, I was just looking for some pointers, or just a different set of eyes on my code, most of stuff I found was for data binding.
Dim p_Count As Integer = 0
Dim conStr As String = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=DellC521-01.redcopper.local)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XE)));User Id=WWW;Password=UTF888888"
Dim cmdQuery As String = "SELECT COUNT(*) FROM WWW.RC$_PRODUCTINDEX"
Dim con As New OracleConnection(conStr)
Dim cmd As New OracleCommand(cmdQuery)
cmd.Connection = con
cmd.CommandType = Data.CommandType.Text
Dim param_MANUFACTURER As OracleParameter
param_MANUFACTURER = New OracleParameter("@MANUFACTURER", OracleDbType.Varchar2, 80)
param_MANUFACTURER.Value = m_Manufacturer
cmd.Parameters.Add(param_MANUFACTURER)
Try
con.Open()
Dim oReader As OracleDataReader = cmd.ExecuteReader
While oReader.Read()
p_Count = oReader.GetInt32(0) 'TheCount
End While
oReader.Close()
con.Close()
oReader = Nothing
Catch ex As Exception
End Try
con = Nothing
cmd = Nothing
Return p_Count

Well that was interesting. This Oracle is a little different on the asp.net side
Oracle didn't like the @ char, so I changed it to :, and you can't name the parameter the same as the column name, so I change the name to just :M1
As far as getting the value, it's GetValue(0), go figure. Not sure if I should cast it to a integer.
So now I see there is a Microsoft Data Access Client for Oracle included in asp.net 4.0, and a Oracle Data Access Client, the one that ships with Oracle 11.g Express, so which one to choose?
Well I choose the one from Oracle, figured maybe it's more fine tuned, I don't know, comments are welcomed.
Well I think I'm ready to start writing code for this now. I welcome any comments or conversation on this subject.
This is what I ended up with so far, it works, but needs further testing.
Dim p_Count As Integer = 0
Dim conStr As String = "Data Source=(DESCRIPTION=(ADDRESS=(PROTOCOL=TCP)(HOST=DellC521-01.redcopper.local)(PORT=1521))(CONNECT_DATA=(SERVICE_NAME=XE))); User Id=PUBLIC_USER; Password=xxxxxxxx"
Dim cmdQuery As String = "SELECT COUNT(*) FROM RC_PUBLIC_USER.RC$_PRODUCTINDEX WHERE MANUFACTURE=:M1"
Dim con As New OracleConnection(conStr)
Dim cmd As New OracleCommand(cmdQuery, con)
cmd.CommandType = Data.CommandType.Text
Dim param_Manufacture As OracleParameter
param_Manufacture = New OracleParameter(":M1", OracleDbType.Varchar2, 80)
param_Manufacture.Value = m_Manufacturer
cmd.Parameters.Add(param_Manufacture)
Try
con.Open()
Dim oReader As OracleDataReader = cmd.ExecuteReader
While oReader.Read()
p_Count = oReader.GetValue(0) 'TheCount
End While
oReader.Close()
con.Close()
oReader = Nothing
Catch ex As Exception
End Try
con = Nothing
cmd = Nothing
Return p_Count

In place of oracle connection i suggest you to go with the oledb connection, Which provided by the .net framework it self
You have to import the library as
Imports System.Data.OleDb
then your code will look like:
Dim p_Count As Integer = 0
Dim conStr As String = ""
Dim cmdQuery As String = ""
Dim con As OleDbConnection = Nothing
Dim cmd As OleDbCommand = Nothing
Dim oReader As OleDbDataReader = Nothing
Try
conStr = "<Connection string for oledb connection>"
cmdQuery = "SELECT COUNT(*) FROM WWW.RC$_PRODUCTINDEX"
con = New OleDbConnection(conStr)
cmd = New OleDbCommand(cmdQuery)
cmd.Connection = con
cmd.CommandType = Data.CommandType.Text
cmd.Parameters.Add("@MANUFACTURER", OleDbType.VarChar, 80).Value = m_Manufacturer
con.Open()
oReader = cmd.ExecuteReader
While oReader.Read()
p_Count = oReader.GetInt32(0) 'TheCount
End While
Catch ex As Exception
Finally
con.Close()
oReader = Nothing
End Try
con = Nothing
cmd = Nothing
Return p_Count

I am interested in making a universal way for all my programs to be able to switch SQL Database Programs, and I think OLEDB was going to be the standard in the future. I did some research on it during my C++ development last year, and I just need to look at my code to see what I used.
I ended up using the Oracle ODP.NET 11.2, the latest one, and finished installing the Oracle 11.g to my production database server, and setup the ODP client on the web server, so I'm ready to go.
i will tool around with teh OLEDB this weekend, and take it for a spin.
Thanks for the discussion on it, anything on the subject is welcomed.

Hi,
I want to create a Facebook application.
Form the examples on the web I see that there's a use of php on the server side.
Is there a way to create the application with asp.net web forms / asp.net MVC and achieve the same results?
Thanks,
Avi

Outside of the server, that difference is not visible. Server code runs on the server, it's only the result that one can see.
There's an example on C# and FB here[^].

Use AJAX.
Sorry, but you'll have to research the technology and see how it will fit in your application.

Use AJAX UpdatePanel control.
Put all the code that is being postback to the server in side the UpdatePanel control
|
|
|
|

Your going to have to use Javascript, and create your sort of fake grid, and update that fake grid in the DOM. At the same time the item is added, you need to use a web service to update the cart with that item. So when you do a postback, all the items can repopulate that same space.
fahad.1 wrote: .It should happen without postback
Update panels do a partial postback of the page, but it's still a postback.
The only way to get around a postback is to use a web service in the background, in combination with Javascript, to just keep manipulating the dom, until you leave the page.
As far as manipulating the Gridview in JavaScript, I have no idea how.
That's alot of work for that feature or confirmation.

I am using dropdownlist in c# asp.net. Here one dropdown list getting data's from database and its having required field validator also.,
My ASP design coding is.,
<asp:dropdownlist id="zonename" runat="server" width="195px" tooltip="Select Zone">
<asp:requiredfieldvalidator id="RequiredFieldValidator1" runat="server" controltovalidate="zonename" errormessage="Zone Name Required" initialvalue="Select Zone">
And MY C# coding is....,
da = new MySqlDataAdapter("select name from zone", mysqlcon);
dt = new DataTable();
da.Fill(dt);
zonename.Items.Clear();
zonename.Items.Add("Select Zone");
for (int i = 0; i <= dt.Rows.Count - 1; i++)
{
zonename.Items.Add(dt.Rows[i]["name"].ToString());
}
mysqlcon.Close();
WHEN I AM SAVING THIS DROPDOWNLIST TEXT TO THE DATABASE.,THE WORD "Select Zone" ONLY GOING TO THE DATABASE.
MY INSERT QUERY IS.,
"insert into TABLENAME(zonename) values('"+zonename.text+"')";
Here i couldnt understand what is going on.,i need to save the selected text to the database. If anybody know how to solve this problem, Please let me know.,
Thanks.,

zonename looks like it is some sort of list so it is unlikely to have a member called text. It would also help if you formatted your code and put <pre> tags around it, to make it more readable thus:
da = new MySqlDataAdapter("select name from zone", mysqlcon);
dt = new DataTable();
da.Fill(dt);
zonename.Items.Clear();
zonename.Items.Add("Select Zone");
for (int i = 0; i <= dt.Rows.Count - 1; i++)
{
zonename.Items.Add(dt.Rows[i]["name"].ToString());
}
mysqlcon.Close();
One of these days I'm going to think of a really clever signature.

Look at the SelectedText and SelectedValue properties of the DropDownList control.
djj55: Nice but may have a permission problem
Pete O'Hanlon: He has my permission to run it.

it's
ddl.items.clear();
ddl.items.add(new listitem("Select a Zone", "--")
ddl.items.add(new listitem(Name, Value));
'Check that the selection is not "--" or > 0
string pvalue = ddl.selectedvalue;
insert into table pvalue
and get the selected value of the ddl, not the selected text

Hi everyone
Please find below the exact code you need in order to prevent cache from being stored. I am posting this in order to help everyone that ever needs it as I spent myself some hours this last saturday trying to do it. I saw many combinations from the same code everywhere in several forums but this is the only one that worked for me comes, as referenced below
After filling a form, then going back to the previous page and then forward back again, the form is empty as expected. Nothing is stored in the browser's cache
Hope it helps
Regards

Alas, it'll be hard to find on the forum, as new messages keep coming in. You might want to submit it as a trick; makes it a bit easier to find.

hi Eddie
I report a totally unrespectful behavoir from two members of this site, Guirec Le Bars and Sandeep Mewara
After following your advise to posting it as a trick I received this from these users:
Guirec Le Bars: "Not an article and not even a tip I guess..."
Sandeep Mewara: "Agree. Not even a tip."
Inmediatly the article was deleted
I am not used to this kind of treatment, I am a respected professional with over 20 years experience in the field
I just re-submitted it and I HOPE it gets published now
I have the right to judge myself if what I write is of any help or not, and not be judged by third parties
After all, I am helping others, not trying to earn a cent from this or anything else

The word "article" implies a longer text with explanation, while a "tip/trick" entry is usually a short description of a solution. Both are available under the same link. This way, the articles all meet certain minimal quality-criteria. A tip/trick would also need some background on why you wrote it, and what problem it solves.

Aah, all registered users have the option to vote on an article, or on tips. If you meet a lot resistance, it might be better to give it a rest for a moment - it's no fun if you get a lot of hard words for one's work. Still, if you ask Sandeep how it should be formatted/worded before it's approved as a "trick" would probably give you a list of tips on the subject.
