I am using asp.net + Mysql.
I have multiple rows in my dataset; I have to store the rows in my database table. How to do that?
My problem is that I have a grid view that show the data from database.In my gridview i add a column name date .like eg You knw that when we send a scrap to anyone then show time how much time to send a scrap.
View 6 RepliesI want to store the current date & time which can be get by System.DateTime.Now in asp.net but while storing in Mysql it gives Error of Invalid Time.
View 3 RepliesI am getting the "Unable to convert MySQL date/time value to System.DateTime" error because from what I can tell I have a record with 0000-00-00 00:00:00. Now while the data should never be that (it should be null) there are cases when this might happen and I don't want my entire application to crash because of it. I am using NHibernate and I tried adding change my connection string to allow zero datetime so the connection string configuration looks like:
<property name="connection.connection_string">
Server=localhost;Database=user_system;User ID=root;Password=root;
Allow Zero Datetime=true;
</property>
However I still receive that error. How can I allow NHibernate to allow zero values for timestamp/datetime/data/time?

Using MySQL 5.
In my SAP.NEt project, defined a constant:
public static DateTime NullDateTime = DateTime.MinValue;
I have a function:
protected static DateTime GetDateTime(DataRow row, string columnName)
{
return (row[columnName] != DBNull.Value) ?
Convert.ToDateTime(row[columnName]) :
Globals.NullDateTime;
}
In the source code:
public DateTime StationFeedTime{ get; set; }
StationFeedTime = GetDateTime(row, "StationFeedTime");
I ran a SQL to fetch records from MySQL, this field is Time field in MySQL.
Got an exception inside the function:
Unable to cast object of type 'System.TimeSpan' to type 'System.IConvertible'.
I have a form which inserts data in DB on Submit button click but the problem is when client click the button multiple times its sends multiple create requests means multiple button click events for the same time of same data, which must not be.
I tried to disable the button when client click the Submit button first time but after this it does not call server click event handler or not fire the server click event once it got disabled.
How to handle this multiple click problem..
I used the following code to disable the button

View 3 RepliesI am using the System.Timers.Timer class. And I enable when I send a message and disable when I receive the message. How do I calculate how much time has elapsed. I have set the interval as 1 sec
Basically I retransmit data after 1000 sec again if I do not recive an ACK. I retransmit 5 times max until I get a Ack. If I receive and something before 150ms then I stop retrnsmission.
Here's the code:
timer1.interval = 1000;
port.Write(data)
timer1.enabled = true;
event handler for the received data.
timer1.enabled=false;
How can i get wcf service to send larger packets of data at a time?
EDIT
So, apparently the default BytesPerRead is 4096, however I've changed that value on both the client and the server. here is the config file
Moreover, I've found an unanswered post dealing with the same issue WCF maxBytesPerRead limit to 4096

View 3 RepliesWhy does a very simple script which inserts 26,000 records into a mysql database (myisam, no transactions) take 13 seconds in the php implementation, and then 35-50 seconds using mono+mysql connector? I thought asp.net was faster than php? Could the problem be the mono mysql connector is "platform independent", so the performance just stinks? or does asp.net suffer more overhead than php when it comes to executing each query? Aren't there any native linux binaries for mysql connector for mono that may be faster?
View 1 RepliesI have used ASD.NET code using SQL Database for Transaction operation successfully. By changing the Database Code to interface with MYSQL an Error occurs. If I remove the Transaction Code from within the the application, it works OK by displaying the MYSQL data (Read Only) in the layout of the application. I am using Mysql Essential-4.1.22-win32 and MYSQL Connector ODBC-3.51.2. My objective is to EDIT the MYSQL Data.

View 5 RepliesThe objective is to send automated emails to which of whom come from the results of my LINQ to SQL script. As I am not sure on 'automated' stuff I was going to approach this in the aspect of having a field in the table that the results are taken from change after the emails have been sent i.e. obj.EmailSent = true; - So that everytime the admin homepage is loaded it isnt sending it out again (eliminating duplication).
From that I would have to create a method to detect a new year and upon that reset all entries of the EmailSent field in the DB table to 'false', but for now its just the initial problem thats causing confusion.
I was going to opt for a 'foreach' solution so that all the recipients, individually, get their emails and not all together. Its the 'foreach' I'm not sure on as well as setting all the results collected to the new value of 'EmailSent' to 'true'.
Here is my attempt:

I'm working on a MVC3 application. I need to send in some cases the same email to several users. What's the best way to do that?
I want that when the same message is sent to more users, every user see his address on the "to" field, but he shouldn't see others email
addresses? In my actual implementation I create a message for every user, but I think that's not really smart.
If I add the addresses in the "bcc" fields, how can I set every time correctly the "to" field avoiding to send duplicate messages?
I also tried this

but obviously it separates with a comma the addresses and so them are all visible.
Which is the best way (in performance and security) to send multiple parameters to a web page (on a different server), considering that the length of the parameters may vary because I'm sending a list of products, and the customer may have selected more than one product, so we need to send each product on the querystring to the other page. For example (I'm on C#); I want to call a web page like this:
Simple Querystring: thepage.asp?Product=1&Name=Coffee&Value=1.99
Json: thepage.asp?{"Product":"1","Name":"Coffee","Value":"1.99"}
XML: thepage.aps?<xml><Products><product>1</product><name>Coffee</name><Value>1.99</Value></Products>
(Obviouly considering we can't send special characters via querystring, but I put them here for better understanding) Which will be the better way (performance, security)?
It's sending multiple emails and I just want to send out one email for each email from the gridview.
[Code]....
I have emails stored in my database. The email is shown by a grid view that contains also a checkbox. I would like to send email to all emails that are selected in checkbox in my gridview. The value that the checkbox hold is True and False.
