RDLC is the embedded version of SSRS. We have used these extensively in winforms and asp environment. There is no Silverlight RDLC viewer (well there is on but it is bloody expensive). We use the server version for our enterprise reporting needs.
SSRS is one of the premier reporting platforms, but then so is DevExpress!
Just don't get involved with crystal reports spit

who's using crystal reports now! 
so let me ask you if you had to choose between DevExpress reports and RDLC, which one you'll choose and why?
Also let me tell you about my scenario..
I am using MySQL backend with WinForm and from application, I want to allow the user to design their own reports or change existing reports using report designer.
Thanks,
Jassim

I would choose RDLC but only because of familiarity. Possibly the support and examples may be more widespread.
While I have deployed the report designer (many years ago) in 2 organisations they were NEVER used, the users always came back to the developer (me) to build the reports. The closest I ever got to user design was where they would dump a set of data to excel, fiddle with it and then get me to build the report.

I've never worked on these old dbase/clipper database files for Account Mate DOS, and I'm having trouble with multiple joins. Says I'm missing a arithmetic operator in the statement. I can't find a reference to study to get an idea of how it should be written. I really don't want to make 2 calls, because it really slows down the load time.
This is the error message
Syntax error (missing operator) in query expression '(c.FCUSTNO = a.FCUSTNO) LEFT JOIN ARCEM01.dbf e ON (c.FCUSTNO = e.FCUSTNO)'.
"SELECT c.FINVNO, c.FCUSTNO, c.FCOMPANY, c.FSALESPN, c.FSHIPVIA, c.FORDDATE, c.FSHIPDATE, c.FNTAXAMT, a.FADDR1 " & _
"FROM ARINV01.dbf c " & _
"LEFT JOIN ARCUS01.dbf a ON (c.FCUSTNO = a.FCUSTNO) " & _
"LEFT JOIN ARCEM01.dbf e ON (c.FCUSTNO = e.FCUSTNO) " & _
"WHERE c.FORDDATE=@startDate"

If I remember correctly (which might not be the case) dbase only allows one outer join. But this doesn't seem to be a real problem as you're not using ARCEM01.dbf for anything.
The solution otherwise would be to use subqueries in the select. Like this:
SELECT c.FINVNO
,c.FCUSTNO
,c.FCOMPANY
,c.FSALESPN
,c.FSHIPVIA
,c.FORDDATE
,c.FSHIPDATE
,c.FNTAXAMT
,(SELECT a.FADDR1 FROM ARCUS01.dbf a WHERE c.FCUSTNO = a.FCUSTNO) as FADDR1
FROM ARINV01.dbf c
WHERE c.FORDDATE=@startDate
|
|
|
|
|
I kind of thought that.
I didn't put the e.FEMAIL1 in for experimenting yet until I got some concrete information on it.
Thanks!

That Works! Thanks Jorgen

Hye, I having a problem with this sql query..
string sql = "SELECT * FROM Environmnets INNER JOIN TDevice ON Environmnets.Deviceid = TDevice.id INNER JOIN TMushroomHouse ON TDevice.MushroomHouseId = TMushroomHouse.id WHERE (Environmnets.DateT =(SELECT MAX(DateT) AS Expr1 FROM Environmnets AS Environmnets_1)) AND TMushroomHouse.Name ='"+ DropDownList1.Text + "'";
SqlConnection con = new SqlConnection(strConnString);
SqlCommand cmd = new SqlCommand(sql, con);
// SqlDataReader dr = cmd.ExecuteReader();
try
{
con.Open();
SqlDataReader dr = cmd.ExecuteReader();
while (dr.Read())
{
HouseTextBox.Text = dr["House"].ToString();
DateTTextBox.Text = dr["DateT"].ToString();
TempInTextBox.Text = dr["TempIn"].ToString();
TempOutTextBox.Text = dr["tempOut"].ToString();
HumidityTextBox.Text = dr["Humidity"].ToString();
}
}
There is no error occur when I run this code, but when I select home from dropdownlist, the data from database didn't display in the textbox. Anybody can help me?

The first problem is that your code is susceptible to SQL Injection[^]. You should be using a parameterized query instead.
While we're fixing that, the SqlConnection, SqlCommand and SqlDataReader objects all implement IDisposable, so they should be wrapped in using blocks to make sure their resources are freed.
We'll also get rid of the SELECT *, since you only need five columns.
string sql = "SELECT House, DateT, TempIn, tempOut, Humidity FROM Environmnets INNER JOIN TDevice ON Environmnets.Deviceid = TDevice.id INNER JOIN TMushroomHouse ON TDevice.MushroomHouseId = TMushroomHouse.id WHERE (Environmnets.DateT = (SELECT MAX(DateT) AS Expr1 FROM Environmnets AS Environmnets_1)) AND TMushroomHouse.Name = @MushroomHouseName";
using (SqlConnection con = new SqlConnection(strConnString))
using (SqlCommand cmd = new SqlCommand(sql, con))
{
cmd.Parameters.AddWithValue("@MushroomHouseName", DropDownList1.Text);
con.Open();
using (SqlDataReader dr = cmd.ExecuteReader())
{
while (dr.Read())
{
HouseTextBox.Text = dr["House"].ToString();
DateTTextBox.Text = dr["DateT"].ToString();
TempInTextBox.Text = dr["TempIn"].ToString();
TempOutTextBox.Text = dr["tempOut"].ToString();
HumidityTextBox.Text = dr["Humidity"].ToString();
}
}
}
Now, if the code is definitely executing, and there's no error, but you're not seeing anything in the textboxes, then that means there were no records returned by your query. If I had to guess, I'd say it's probably connected to the DateT filter:
WHERE (Environmnets.DateT = (SELECT MAX(DateT) AS Expr1 FROM Environmnets AS Environmnets_1))
I suspect you want the last record for a specific TMushroomHouse, but you're actually only looking for the last record overall, and only returning it if it matches the selected house.
If that's the case, try changing your query to:
SELECT TOP 1 House, DateT, TempIn, tempOut, Humidity FROM Environmnets INNER JOIN TDevice ON Environmnets.Deviceid = TDevice.id INNER JOIN TMushroomHouse ON TDevice.MushroomHouseId = TMushroomHouse.id WHERE TMushroomHouse.Name = @MushroomHouseName ORDER BY Environmnets.DateT DESC

Tq..it working right now  And I have one more question, mushroomhousename is not the same table with environmnets..how i want to call mushroomhousename and put it in a textbox?
|
|
|
|
|
Try something like:
SELECT TOP 1 House, DateT, TempIn, tempOut, Humidity, TMushroomHouse.Name As MushroomHouseName FROM Environmnets INNER JOIN TDevice ON Environmnets.Deviceid = TDevice.id INNER JOIN TMushroomHouse ON TDevice.MushroomHouseId = TMushroomHouse.id WHERE TMushroomHouse.Name = @MushroomHouseName ORDER BY Environmnets.DateT DESC
This adds the Name column from the TMushroomHouse table as a new result column called MushroomHouseName. You can then read it from your code and put it in a textbox:
while (dr.Read())
{
...
MushroomHouseTextBox.Text = dr["MushroomHouseName"].ToString();
}
"These people looked deep within my soul and assigned me a number based on the order in which I joined."

Hi,
I am having the above error on my .net application. It only shows on customer screen with a basix SELECT statement. Currently I have only 1600 customers in the customers table
This error is not shown on any of the other screens except the customer screen.
My connection timeout is 360 and I even tried to increase it to 800 but getting the same error for the customer screen!
what could be the problem please?
Thanks,
Jassim

You're referencing to something that's not there; the exception message comes from one of your older posts. Simply include it with the rest of the text.
Can you connect at all to that particular server? Using Telnet[^]?

Yes I can. I am also able to view invoices, employees and all other data from the same database on the same server using the same .net application. Exceptions occurs on the customers only.
Any timeout parameter or variable I should try to look at?

I would suggest you look at the customer query then, it is not your connection, that works for other queries!

this is my query:
SELECT customer_id, id_number, customer_name, email_address, landline_number, mobile_number, customer_address_building, customer_address_road, customer_address_block, customer_address_landmark, allow_delete, is_blacklist, is_inactive FROM customers ORDER BY customer_name;

There is no WHERE clause?!

no WHERE. I am filtering using the XtraGrid. It will be maximum of 2000 records which I though MySQL will be able to handle it easily.

Stop pointing fingers; it's not MySQL that's failing, but a third-party component.
You might try to connect using another user/role/password at the customers site. And update your MySQL data provider

My bad; it could have been, depending on language and intonation
I usually take the exception-message as a starting point;Jassim Rahma wrote: "MySQL A connection attempt failed because the connected third party did not properly respond after a period of time"
Plan of attack;
- Create a console-app, use the users' credentials, and try a minimal query (SELECT 1 or something similar)
- Test once with your current data provider (MySQL Connector.NET?)
- Copy the project, try another data provider (MySQLDotNET[^])
- Try the same again, using the dba-account.
If you can terminal to MySQL, then the server is there; that you said was true. That means that you can skip checking the firewall and the port on which MySQL speaks. The reason I'm asking to test with the dba's account is that he should have unrestricted access to all tables. If that one connects correctly, then you'd need to do some extra grants on your users' accounts.
What does your connection-string look like? Can you post it here? (Without the login-info)

Hi,
I am using this code to loop from start date to end date and add job orders into MySQL table. I only have one problem here. If My start date is 14 April 2014 it will insert records from 15 April 2014 so it's skipping my start date.

So I had a hard time finding where your loop started, so I can't give you details on why its happening. However I can give you a tried and true method to find the issue (its worked for over 30 years for me)
Play computer:
Take a few sheets of paper and write down what you "expect" to happen in plain English.
Then write down the algorithm your code is following in plain English.
Compare - figure out the mis-match, you may need to search vendor docs to find the "gotcha"
Still no luck finding out whats going wrong?
Take a small record set and run it through your written algorithm.
99.9999% of the time this method works!
Good luck
