Hi all I am having a problem with a program i have been working on and I have been filtering a database by date and client to produce records for a DBChar and it all works fine and as it should . As the record number grows thought I should perhaps use an sql query insted of filter and do you think I can get it to work I have a SDF Database called CounterData. I have a field in the database counterDate which is a datetime field  and I have two datetimepickers one startdate and one enddate. I not strong on sql and can usually make it do what I want but not with dates. have tried many variants of this select  * from counterdata where countertranstype ='+quotedstr('D')+'and CounterDate >='+datetostr(startdate.date) +'and counterDate <='+datetostr(enddate.date). I am using the Devart Sdac components to connect to the SDF Database Thanks for any help Owen Moore

I have written a program that does soundanalyses with a FFT-function. To view the data I want to display it in a spectrogram. The method I have applied now is drawing the frequencies on the vertical axis and time on the horizontal axis. The amplitude of the signal is displayed using different colors. To draw the colors on the bitmap I currently use the Pixel function of the Canvas, but this goes really slow., , My question is : Is there another, faster method to draw colors on the bitmap; keeping in mind that every pixel could have another color?

Hi,, Does anyone know how to make a program process every setting in an ini file?, , I have 2 problem settings in my program that can't seem to process the results from the ini file, one is "Always on top" and the other is "minimize to tray". My program can save the settings with no problems but when I run the program and it reads the ini file, if both settings are set to true the program only seems to process one of them., , My guess is because both settings relate to window functions. I tried Application.ProcessMessage but that didn't fix the problem., , Any help or suggestions would be appreciated., , Merlin

Hello everyone!  I am new to Delphi and I am picking it up really quickly by the way.  My problem is I haven't seen a working Mysql database that worked from examples I have downloaded.  I have gotten a few Access database running with Delphi.  What I can't seem to do however is get a certain recordset.  I can't find no information on pulling a specific recordset with Access/Delphi. Here is what I am trying to do:  when a person logs on to the chatroom server, I want them to have access  to the information they entered in there personal record only? If there is an easier way to do this besides using Access, can someone point me in the right direction please.  I am using Delphi 7. Thanking you all in advance!!!

I am having a speed problem when writing new values to a MS Access table via and ADO connection.  On the first pass through the dataset there is no problem, with more than 1000 records per second being updated.  But on the second pass through, it slows to about 10 records per second, even though the task is much simpler. Just the fact that I try to update just one field seems to trigger the slow speed on the second pass.  I am using a TADOConnection and a TADOTable to connect to the Acces table.  To update the filed values I am using...    MyADOTable['MyFieldName'] := NewFieldvalue; Some parameters for the connection include... ConnectionString = Provider=Microsoft.Jet.OLEDB.4.0;Mode=Share Deny None;Persist Security Info=False, CursorLocation = clUseServer, Provider = Microsoft.Jet.OLEDB.4.0 Can anyone suggest what might be causing the problem or any possible solutions.  Regards  Ron

Hi everyone, I hope someone could help me solve this problem out, cause I'm stuck with this since a few days... I have this little script:, , procedure TForm1.Button1Click(Sender: TObject);, var, sBusca:string;, , begin, ADOQuery1.Close;, ADOQuery1.SQL.Clear;, sBusca := Edit1.Text;, ADOQuery1.sql.add('Select * from cobranza where nombre = '+QuotedStr(sBusca));, ADOQuery1.Open;, end;, , end., , I'm trying to search for a Name into table Cobranza, the problem is that when I compile the script, it runs, but when I push the button it does nothing... so, if I get no error how can I know what's wrong?, , I wish someone could throw a lite into my darkness. Oh, one thing, originally I was trying to use 'Select * from Cobranza where nombre LIKE "%cBusca%" ';, in order to find names that have some likeness with the search, but it doesn't work either..., , Thanks in advance., Francisco V.

I have some results in the form of tabulated text, numbers etc., that I would like to get print preview on. Can anyone point me in the right direction on this. Sample code would be appreciated.

How do you get an application to simultaneously load and load a data file that has been double clicked on or opened? Of course, I realize that you need to associate the file with the program first.
