You should take a look at this site[^].
What you're trying to do would result in this 3x3 matrix:
[ scaleX 0 0 ]
[ 0 -scaleY 0 ] [ OffsetX OffsetY 1 ]
Multiplying your (x,y,1) coordinate with this matrix should result in what you're trying to do.

Thank you Greeeg
Now I have to find out how to set those values in the GDI Matrix

Thank you Greeed
I've tryed several ways to set a Transformmatrix with GDI but it does't work !
Here is what I'm doing outside the matrix :
X=(X-OfsetX)* Scale
Y=(Y-OfsetY)* Scale
Y=abs(Y-ImageHeight)
It works well
The real problem is the inversion of Y from the "real" world to an Image origin
If I set the Matrix as this
Matrix m=new Matrix();
m.Translate(-offset_Xf, -offset_Yf, MatrixOrder.Append);
m.Scale(scale_f, scale_f, MatrixOrder.Append);
My Y is reversed in the image
And I still do not find to set the matrix properly !

I'm working on an ASP.Net application accessing couple of database tables from AS400 mainframe server database. In the code there's an SQL Query, which seems very complicated to me, the person who did the actual coding is no more with our firm.
Right now the query is producing some kinda result which is wrong. So can anyone please help me out in finding what's wrong with the SQL query? The SQL query is attached below:
Me.OdbcSelectCommand2.CommandText = "SELECT SAMFILE.STAYP.SCLINT, SAMFILE.STAYP.SADMHH, SAMFILE.STAYP.SADMYY, SAMFILE.STAYP.SADMMM, SAMFILE.STAYP.SBLDG, SAMFILE.STAYP.SADMDD, SAMFILE.STAYP.STRMCD, SAMFILE.STAYP.STRMHH, SAMFILE.STAYP.STRMYY, SAMFILE.STAYP.STRMMM, SAMFILE.STAYP.STRMDD, SAMFILE.CLIENTP.CNAME, SAMFILE.CLIENTP.CRACE1, SAMFILE.CLIENTP.CRACE2, SAMFILE.CLIENTP.CRELIG, SAMFILE.CLIENTP.CSEX, SAMFILE.CLIENTP.CBTHHH, SAMFILE.CLIENTP.CBTHYY, SAMFILE.CLIENTP.CBTHMM, SAMFILE.CLIENTP.CBTHDD, SAMFILE.REFSRP.REFSDS, SAMFILE.STAYP.SMDPM, SAMFILE.STAYP.SREFRL, SAMFILE.STAYP.SADRG1, SAMFILE.STAYP.SADRG2, SAMFILE.RACETP.RACEDS, SAMFILE.RELIGP.RELGDS, SAMFILE.STAYP.SADMAG FROM SAMFILE.REFSRP, SAMFILE.RELIGP, SAMFILE.RACETP, { oj SAMFILE.STAYP LEFT OUTER "JOIN SAMFILE.CLIENTP ON SAMFILE.STAYP.SCLINT = SAMFILE.CLIENTP.""CLNT#""} WHERE SAMFILE.REFSRP.REFSCD = SAMFILE.STAYP.SREFRL AND SAMFILE.RELIGP.RELGCD = SAMFILE.CLIENTP.CRELIG AND SAMFILE.RACETP.RACECD = SAMFILE.CLIENTP.CRACE1" // After some loop conditions, the OdbcSelectCommand2 is used in 4 concatenations like this. OdbcSelectCommand2.CommandText = OdbcSelectCommand2.CommandText & " AND (({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT(digits(SADMHH), digits(SADMYY)) }, '-') }, digits(SADMMM)) }, '-') }, digits(SADMDD)) } <= { d '" & End_date_conv & "' })"OdbcSelectCommand2.CommandText = OdbcSelectCommand2.CommandText & " AND ({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT(digits(STRMHH), digits(STRMYY)) }, '-') }, digits(STRMMM)) }, '-') }, digits(STRMDD)) } >= { d '" & Start_date_conv & "' })"OdbcSelectCommand2.CommandText = OdbcSelectCommand2.CommandText & " OR ({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT({ fn CONCAT(digits(SADMHH), digits(SADMYY)) }, '-') }, digits(SADMMM)) }, '-') }, digits(SADMDD)) } <= { d '" & End_date_conv & "' })"OdbcSelectCommand2.CommandText = OdbcSelectCommand2.CommandText & " AND (SAMFILE.STAYP.STRMCD = 0))" // To get the desired result, one more table is suppossed to be used, i.e MOVESP table, but its a tremendously huge table containing records of more than 30+ years and each id is having multiple records and to get the expected result it should be used in the code as something like this. But everytime I try this, it throws an exception "System.outofmemoryexception". I tried increasing the physical and virtual RAM and even timeout durations too but all in vain. OdbcSelectCommand2.CommandText = OdbcSelectCommand2.CommandText & " AND (SAMFILE.MOVESP.MCODE = 'A'))"
Note:
This query works but it fetches wrong information. In the below query I want to replace the last condition (SAMFILE.STAYP.STRMCD = 0) with this new condition (SAMFILE.MOVESP.MCODE = ""A"") and I believe this will make it to fetch the right values to display on the crystal report. But whenever I try to include this new code alongwith other necessary changes it shoots up an erorr message. And the other changes which I make are like :
1. Adding a new element by the name "MCODE" in "as400ds2.xsd"
2. Adding [New System.Data.Common.DataColumnMapping("MCODE", "MCODE")] into the OdbcDataAdapter.TableMappings.AddRange section.
Thanking you all in anticipation

YOu say the query "shoots up an error message". Care to post it? we're not psychics.

cool down bro........!!!
reg. the erro msg : whn i add this piece of code in the end
of the SQL string (SAMFILE.MOVESP.MCODE = ""A""),
the error message is : ERROR [42S22] [IBM][iSeries ACCESS ODBC
Driver][DB2 UDB]SQL0206 - Column A not in specified tables.
and whn I change it to : SAMFILE.MOVESP.MCODE = 'A',
it takes a long time to process the webpage and after a prolonged
period of time, shows the "Page cannot be displayed" error message.

without the last piece of code [SAMFILE.MOVESP.MCODE = A] also, this query works but it gives an incorrect result.
and the only code which can fetch the true values wud be if we include the MCODE code.

I think your problem is outside the scope of this forum, and maybe of any forum here.

Have you tried getting a wrking query directly against the database without involving odbc?
When it works there inclue it in your asp page.

as mentioned, the database is on AS/400 Mainframe server.
without odbc how can i chk the query.
can u guide me on how to proceed with this?

I feel really sorry for your employer, letting you lose with such equipment...
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - out now! ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

I have no idea about as400 database utilities, but every database I have ever come across has some utility to allow you to run queries. I suggest you speak to one of your colleagues and find out how to do it.
