Hi,
This is my situation, I have a ASP.NET website that has a mysql database behind it.
I can't work out how to store news articles.
Basically my news articles are written in MS word and saved as web pages, then changed to .txt files to give me the html code that will display the text the same as it is diplayed in the original word file.
But I can't store this html string in my mysql database using a gridview insert command to insert it. It doesn't like special characters. The mysql field type is text.
At the moment I am getting around it by just storing the .txt file name in the database, then finding it, and using StreamReader to read the html code. This works fine, but it means every news article has to be stored as a .txt file in the server file. I won't to be able to save this data in the database.
I don't won't to open a new page to display the news article.
Am I going about this the wrong way, is there a better way to store news articles?
Is there a way to insert the special characters into the mysql database using gridview?

yes.., in the cart.aspx.vb:
itemPilihan = CType(Me.PreviousPage,_default).datalist()
my errors is _default ("type _default is not defined").
i want to take class _default from default.aspx.vb. but the cart.aspx.vb can not detect the class _default.
if i debug program, it can detect, but sometimes can not detect, so, i rebuild website, it can detect, but sometimes not again, so i rebuild again..again..
that datalist is not type, but is name of function in default.aspx.vb.
pls, copy default.aspx,default.aspx.vb, cart.aspx,cart.aspx.vb to your computer.
and try it..my table is only one like items(kode(varchar),name(varchar),cost(money)).
many member that answer my question are not try my data, they only reading that page, then answer it, so it can not work...
pls...thx...

helo all...,
i have create procedure can decrease totalcost from order table(database:games.dbo) with balance in bill table(database:bank.dbo). my 2 database in same server is name "boy"
i have 2 database like: bank.dbo and games.dbo
in games.dbo, have a table name is order(user_id,no_order,date,totalcost)
in bank.dbo, have a table name like is bill(no_bill,balance)
this is a list of bill table
no_bill balance
111222 200$
222444 10$
this is a list of order table
user_id no_order date totalcost
a 1 1/1/07 50$
when customer insert no_bill(111222) in page and click a button, then bill table became
no_bill balance
111222 150$
222444 10$
when customer insert no_bill(222444) in page and click a button, then message "sorry, your balance is not enough"
mystore procedure like:
ALTER PROCEDURE [dbo].[pay]
(
@no_bill AS INT,
@no_order AS int,
@totalcost AS money
)
AS
BEGIN
BEGIN TRANSACTION
DECLARE @balanc AS money
SET @balanc= (SELECT [balance] FROM Bank.dbo.bill WHERE [no_bill] = @no_bill)
UPDATE [bank.dbo.bill]
SET
[balance] = @balanc - @totalcost
WHERE
[no_bill] = @no_bill
COMMIT TRANSACTION
END
it can decrease money in bank, but i want it ceck money if balance > totalcost, so balance-totalcost,
if balance<totalcost,so error="" message"sorry,="" your="" balance="" is="" not="" enough"
when="" i="" execute="" store="" procedure="" pay,="" insert="" no_bill,no_order,totalcost.
i="" want="" if="" totalcost="" that=""> balance, it display message"sorry, your balance is not enough"
is it can make in procedure?
thx...

Include a IF condition in the procedure that checks whether the Acc.Balance is greater than the TotalCost. If yes Update the Balance and Commit transaction else Raise error and rollback transaction.

my store procedure like that:
ALTER PROCEDURE [bank].[dbo].[pay]

@no_bill INT,
@no_order int,
@totalcost money,
@message varchar(100) -- make it output parameter in your stored procedure
)
AS
BEGIN TRANSACTION
DECLARE @balance AS money
select @balance = balance
from bank.dbo.bill
where no_bill = @no_bill
select @totalcost = totalcost
from games.dbo.totalcost
where no_order = @no_order
if (@balance > @totalcost)
begin
set @balance = @balance - @totalcost
UPDATE bank.dbo.bill
SET
[balance] = @balance
WHERE [no_bill] = @no_bill
-- set @message = 'your have enough balance'
end
else
begin
set @message = 'sorry, your balance not enough'
end
COMMIT TRANSACTION
set nocount off

By using DataRelation , we can able to fetch the matched records of two datatables.
How can i get the unmatched records of the two datatables in code behind?
Note : Note in MS-SQL Query.
For example
Datatable 1
----------------
Id
---
100
101
102
103
104
Datatable 2
----------------
Id
----
100
102
My Expecting result is
Id
----
101
103
104

The Knowledge wrote: cmdClick.Attributes.Add("onClick","document.Form1.txtID.value=manojTextBox.document.body.innerHTML");
try something like this instead
var iFrame= document.getElementById("IFrame1");<br />
document.getElementById("txtID").value = iFrame.document.innerHTML;
and have a look at the below link

Hello
I am a beginner and I really need hlp
The problem is that :-
I want to display the Button id of the button which has been clicked on a new page on being clicked and the text also i mean buton.text.
Mrinal

Do you mean that you want to pass the button ID and TEXT to the new page on the click of a Button? If yes...
On the button click event use Reponse.Redirect to call the new page. Along wi the page URL you can pass the button ID and TEXT as query string values.
something like this...
Response.Redirect("NewPage.aspx?btnId=" + btn.ID + "&btntext=" + btn.Text, False)
and In the New page you can retrieve the values using Request object.
Request.QueryString("btnId")<br />
Request.QueryString("btntext")
the above statement will give you the vaues that you passed from the actual page.
