Here is the current problem. EasyLanguage is a language developed for programming under TradeStation, which is designed specifically for professional traders.
I have an indicator that is programmed in EasyLanguage that references an Entitlement DLL file. The variables are listed in the Easy Language code (pasted below) and what happens is that each customer is assigned a unique customerid in TradeStation (EasyLanguage). When they insert the indicator, the indicator calls the entitlement.dll. The DLL goes to the specified website and verifies that the customer is authorized to use the indicator. If yes then the indicator is displayed. If not then an error message is generated that states the user is unauthorized to use the indicator.
f you can recreate the DLL that would be great, otherwise I need to recreate the PHP portion.
EasyLanguage Code:
DefineDLLFunc:
"entitlements.dll",
INT,
"GetEntitlements",
LPSTR,
INT,
LPSTR,
LPSTR,
LPSTR,
LPSTR,
LPSTR,
BOOL;
Variables:
EntitlementName("Test"),
HostIP("207.126.53.83 "),
HostPort(80),
HostPath("www.tradershelpdesk.com/entitlement/BSGTS2.php "),
HostPassword (""),
IsEntitled(0),
pErrorMessage(""),
theErrorMessage("Warning ! You are not entitled to use this tool!" + "For test");
if (currentbar=1) then
begin
IsEntitled = GetEntitlements((LPSTR) HostIP,
(INT) HostPort,
(LPSTR) HostPath,
(LPSTR) HostPassword,
(LPSTR) numtostr(customerid,0),
(LPSTR)EntitlementName,
(LPSTR) pErrorMessage,
(BOOL)True);
end;
If(IsEntitled<=0) Then RaiseRunTimeError(theErrorMessage);
inputs:
Price( Close ),
Length( 14 ),
HiAlert( 0 ), { pass in 10 for +10% }
LoAlert( 0 ), { pass in -10 for -10% }
UpColor( Cyan ),
DnColor( Red ) ;
variables:
PctChg( 0 ) ;
PctChg = 100 * PercentChange( Price, Length ) ;
Plot1( PctChg, "%Chg" ) ;
Plot2( HiAlert, "HiAlert" ) ;
Plot3( LoAlert, "LoAlert" ) ;
{ Color criteria }
if PctChg > HiAlert then
SetPlotColor( 1, UpColor )
else if PctChg < LoAlert then
SetPlotColor( 1, DnColor ) ;
{ Alert criteria }
if PctChg crosses over HiAlert then
Alert( "Bullish alert" )
else if PctChg crosses under LoAlert then
Alert( "Bearish alert" ) ;

And what exactly is the problem here? You want us to write this code for you? I'm sorry, but this isn't RentACoder.

I am developing developing a hostel booking system, and I am trying to come up with a query that allows me to find all the rooms that are availiable on a particular day. I have tried using the except statement but it has not work, and I have also tried using a temporary table, but that has not worked. I have also attempted to select all the rooms that are availiable on a particular day and after that I have conducted a left join on the rooms tables, so as to try identify the rooms that have null values. Does any one out there no how this could be done using SQL 2000 or access
I have included a definition of the database below.
--Stores the database for the hostel--
create database Ymcadatabase
on Primary
(Name = 'ymca_data',
Filename = 'c:\YDbase\ymca_data.mdf',
size = 5mb,
Filegrowth = 10%)
Log ON (Name = 'ymca_log',
FILENAME = 'c:\YDbase\ymca_log.ldf',
SIZE = 5mb,
FILEGROWTH = 10%)
GO
The table definitions
use Ymcadatabase
go
create table rooms
(
roomNumber char(5) Not Null,
block char(50) Not Null,
roomStatus char(10) Null,
rate money Not Null,
Primary Key (roomNumber),
)
create table guestInfo

roomNumber char(5) not null references rooms(roomNumber),
sessionNumber int Not null references sessions(sessionNumber),

Good morning.
I converted a report from Access2k to SQL Reporting and one of the sql strings that were part of a control is giving me problems and I cannot seem to run it down. I was hoping someone on here could point out the error to me.
The error message I recieve is:
Msg 403, Level 16, State 1, Line 1
Invalid operator for data type. Operator equals boolean AND, type equals varchar.
The select statement is:
SELECT tblPatients.*, <br />

ORDER BY tblPatients.LastName, tblPatients.FirstName, tblPatients.MiddleInitial
I apologize for the mess code. I tried formatting it better with no luck.
Before the error above I was getting complaints about the table name tlkpOutPhysicians saying there was a syntax error around there, never could figure that out. The table is there along with the rest.
Thanks, hope someone can shed some light on it.

Try this in the FROM clause:
FROM
tblPatients
LEFT OUTER JOIN tlkpOutPhysicians
ON tblPatients.PatientPhysician = tlkpOutPhysicians.PatientPhysicianNumber
LEFT OUTER JOIN tlkpMaritalStatus
ON tblPatients.MaritalStatus = tlkpMaritalStatus.StatusNumber
LEFT OUTER JOIN tlkpOverweightTimeframe
ON tblPatients.OverweightTimeframeID = tlkpOverweightTimeframe.OverweightTimeframeID
LEFT OUTER JOIN tlkpProcedures
ON tblPatients.PreferredProcedure = tlkpProcedures.ProcedureNumber
LEFT OUTER JOIN tlkpBWLSStaff
ON tblPatients.SurgeonOfChoice = tlkpBWLSStaff.BWLSStaffNumber
LEFT OUTER JOIN tlkpReferralSources
ON tblPatients.ReputationSource = tlkpReferralSources.ReferralSourceNumber
LEFT OUTER JOIN tlkpSurgeonChangeReasons
ON tblPatients.ReasonSurgeonChoiceChanged = tlkpSurgeonChangeReasons.SurgeonChangeReasonID
P.S. You cannot format with TABS on this site. You must use spaces.

Thank you Michael for the reply and help. However, it's still complaining about line 1 and giving me the same error: Msg 403, Level 16, State 1, Line 1
Invalid operator for data type. Operator equals boolean AND, type equals varchar.
I did replace my FROM section with what you have above. Thanks.

Hi Steve
The & characters are worrying me a bit. Which database product are you using? Under SQL-Server, you should be using "+" signs. Under Oracle you would normally use the pipe symbol.
Try replacing the entire list of columns in your select with "*". That will tell you whether the error comes from the column-list or from the from-clause. Once you know this, you should be able to narrow the problem down further.
Regards
Andy

ISNULL(tlkpBWLSStaff.FirstName, NULL) &
ISNULL(tlkpBWLSStaff.MiddleInitialName, NULL) &
ISNULL(tlkpBWLSStaff.LastName, NULL) AS PreferredSurgeon
Not sure what you are trying to accomplish with this line. & is a bitwise operator, ISNULL([whatever],NULL) doesn't do anything productive that I can think of. Can you do a bitwise & with character data?
Are you trying to build a full name?
ISNULL(tlkpBWLSStaff.FirstName + ' ', '') +
ISNULL(tlkpBWLSStaff.MiddleInitialName + ' ', '') +
ISNULL(tlkpBWLSStaff.LastName, '') AS PreferredSurgeon
To debug the rest of you statement eliminate all tables/columns except tblPatients. Run the query and check results. Add in the next table and run again. In this way you will isolate the error in its most simplistic form.
Be aware that you are listing some columns more than once (a waste of network resources). tblPatients.* gets you all the columns in tblPatients. You then go and relist some columns individually (tblPatients.PatientHospitalNumber, etc.).

|
|
|

Great points. I can definitly see the wasted resources in this statement and will take your suggestion to shorten it.
I believe with the Name issue you mentioned, it was just putting the first, middle and last name together. Bare in mind that this came from an Access 97 (then converted to 2k) database report. I converted it to SQL Reporting and trying to redo all the bad sql statements, including this one.

Hi,
i have a parent and child tables. when i am deleting a row from a parent table i want to check wheter that value in Primarykey column exits in childtables or not(it is a forien key in child tables) without mentioning the child table names.ie; i should be generic..i am using sqlserver 2005.
Anu

Then you will have to write some SQL that examines the dependencies of a table, find the relationships then traverses it and examine the child table. You might be able to wrap this up into a UDF (User Defined Function) but I can't imagine that it would be very quick.
|
|
|
|
|
If you want it to prevent deletes if there are child rows, why not just make sure that cascading deletes is switched off on your tables?
Deja View - the feeling that you've seen this post before.

How can i switched of cascading deletes. actually i am not deleting the full record from parent table.just i want to check checking whether it contains child rows or not
Anu
|
|
|
|
|
OK - the cascading ability is maintained per FK relationship. As you aren't actually performing a delete - you are only doing an update, you are going to have to do this the way that Colin suggested.

hello ,
i having a problem in SQL.
i will explain my problem with a simple example.
lets say i have a table called "MyTable" with the following headers:
SKU , TITLE , USER , PRICE , QUANTITY , TOTAL_PRICE
the values are:
avs123 ,some title , udikantz , 2.0 , 1 , 2.0
avs123 ,some title , codeproject , 2.0 , 10 , 20.0
avs123 ,some title , baboon , 2.0 , 5 , 10.0
lol22 , some title2 , hehe , 5.0 , 2 , 10.0
lol22 , some title2 , hoho , 5.0 , 1 , 5.0
i am trying to write a query that will output the following table:
SKU TITLE PRICE QUANTITY TOTAL_PRICE
------------------------------------------------------
avs123 some title 2.0 16 32
lol22 some title2 5.0 3 15
so what im trying to do exactly is to group all the SKU items with the same SKU string to one row and Sum the quantity of all the grouped SKUS
I was trying to manage that by using the distinct statement...
Net
|
|
|
|
|
You could try a GROUP BY and some aggregate functions.
SELECT SKU, TITLE, AVG(PRICE), SUM(QUANTITY), SUM(TOTAL_PRICE)<br />
FROM MyTable<br />
ORDER BY SKU, TITLE
|
|
|
|
|
if i understand what u are saying you probably ment:
SELECT SKU, TITLE, AVG(PRICE), SUM(QUANTITY), SUM(TOTAL_PRICE)
FROM MyTable
Group BY SKU, TITLE
and not
...
...
...
ORDER BY SKU, TITLE
well that is not working for me , Cause my table contain a few more fields i didnt mention in the example ,
more headers like : COLOR , SIZE , COMMENTS ,...
which may be diferent in any ROW
so when im doing
...
...
...
...
Group BY COLOR,SIZE,TITLE,SKU....ect
im getting the same table as "MyTable"
any other idea?

Perhaps you should have done.

hey ,
is it possible to set the cells of a DataGridView so if the content
of a cell is longer than a certain amount of chars ,
the cell will split the text into few lines as needed...
as for now i get cells with long lines and i didnt find any way
to adjust the cells as multiline cells , im sure there is a way of doing that.
what properties , methods would solve my problem?
thanks.
