thanks for the info. i suspect it is the actual servers themselves. space available, disk cache and memory seem to be possible bottlenecks and my program is doing it correctly still. written back for sql 2005/2008 era. sounds like it is still viable solution now.

generally speaking 10GB+ SQL server range from 2008r2 and up. Client last week had 42GB on SQL 2012 and it took about 40-45 minutes to complete the backup/restore process. This is run on the actual server while it is in use on the production database. and lots of times i see the SQL Server app using up 90% of the memory on those servers. sometimes i force clients to exit applications using the database then restart the SQL service, which drops the memory usage and then i run my app. < 20-30 minutes for a particular client who indicated that it had been running for 1.5 hrs.

in my code i use BACKUP DATABASE PRODUCTION TO DISK = C:\TEMP\TESTDATABASE.BAK WITH INIT then RESTORE DATABASE TESTDATABASE FROM DISK = C:\TEMP\TESTDATABASE.BAK WITH MOVE "logicalname" TO "location\testdatabase.mdf", REPLACE same for ldf file Is the with INIT slower than the with FORMAT?
-
interesting, but i don't have complete trust in support to manually do all that so i use delphi with adoconnection, adocommand to process it all to ensure the names never get mixed up and overwritten. hoping for a better component or option to create the copy (test database from a production database)
-
i have a program (old) that creates a backup of a database then restores that database with a different name. it keeps all the users/stored procs/whatever. Is there a newer/better way to create a copy of an MSSQL database? Currently support team is saying that it takes a long time to finish.

well crap, now i find the miscoptions and checksupport. sorry for post and thanks

old program shows the checkbox but new compiled program with gui changes not related to tree does not show checkbox

NOTE: Found issue. No replies needed. Except for scolding.... I had a project that was working with the VST and checkboxes showing up. i had to move project to a new pc and get the virtual components installed. i can now compile project without errors but lost something along the way. i used this code to add the nodes with a check box: function AddVSTObject(AVST: TCustomVirtualStringTree; ANode: PVirtualNode; AObject: TObject): PVirtualNode; var Data: PClassRoomData; begin Result:=AVST.AddChild(ANode); Result.CheckType := ctTriStateCheckBox; AVST.ValidateNode(Result,False); Data:=AVST.GetNodeData(Result); Data^.FObject:=AObject; end; It will display the tree with all the info but the checkboxes do not display. i checked the properties of the vst and found nothing related to checkboxes. so any ideas as to what i could check to get the checkboxes to show up?

i have multiple text files (not a lot of records < 3-4K) that i need to search thru finding matches based upon user input. example: Date, Time, Descript_1, Value_1, Descript_2, Value_2, Descript_3, Value 3, Descript_4, Value_4 01/01/24,08:00:00,Springs, 25, Nuts, 14, Bolts, 75, washers, 207 01/01/24,08:00:15,Springs, 25,Bolts, 35,Nuts,1,washers,12 and so on. now in the past i have loaded up the files to SQL tables and then search for the matches. works ok but now user wants to enter all of the search parameters into a file and do all the searching at once. again not a big deal since i can again read and search. Not that it takes a long time but his system isn't that up to speed and IS rather slow at searching. SO now i want to change the process. I want to create a record array of the date, time, description and values. then just read his search input file (without creating a new record array) and just do a search directly on the record arrays. I have searched and found the TList but they only show a single column matching whereas i need to match the descript_# and value_# for each pairing. like the descript_1 = Springs and value_1=25, then compare the next group because they all have to match in the same sequence. 1's have to match, 2's have to match, 3's have to match and the 4's i am trying to understand TList but so far am falling short type TMyRec = packed record dt : Tdate; tm " Ttime; d1 : string; v1 : integer; d2 : string; v2 : integer; d3 : string; v3 : integer; d4 : string; v4 : integer; end;

cool thanks. probably why i never found sample code. but i did see the zlib examples and will go that route. gzip

i have seen lots of examples for get and decompress of data but nothing really for compress and post. after creating the idCompressor and assigning it to the idHTTP what needs to happen to compress the sRequest FileStream? sRequest and sResponse are TFileStreams ... idHTTP := TidHTTP.Create; idCompressor := TidCompressorZLib.Create(idHTTP); idHTTP.Compressor := idCompressor; idHTTP.ConnectTimeout := 60000; idHTTP.HTTPOptions := [hoKeepOrigProtocol,hoForceEncodeParams]; idHTTP.ReadTimeout := 60000; idHTTP.HandleRedirects := True; idHTTP.IOHandler := SSLHandler; idHTTP.Request.BasicAuthentication := false; idHTTP.Request.CustomHeaders.Values['Authorization'] := 'Bearer ' + _token; idHTTP.Request.ContentType := string(aContentType); idHTTP.Request.CharSet := string(aCharSet); idHTTP.Post(trim(string(aURL)), sRequest, sResponse);

Trying to figure out how to add a shape (rectangle, small) to fast report page. SO user clicks on answers (test page) and then need to put a square/circle/whatever to indicate their answer to the question. questions random the answers (A, B, C, D) so the shape object would not be fixed location.

Not sure it has anything to do with errors or not but i had learn Jenkins which requires Java 17+ for latest version. about a month or so after that i needed to change delphi dll. however, when i start RAD Studio i get like 22 errors on the startup screen all pretty much the same format. An error has occurred in the script on this page. blah blah blah URL: https://...blah.../js/jquery/jquery.min.js Also around this time our IT dept locked up a bunch more stuff. I have JAVA 21.0.2 installed. i searched for these errors but nothing came up. is it my pc/java or is it something else running interference?

thank you for the info/input. the background on this is that way back in 2014 or prior a dll was create using the DCP Crypto libraries. the blowfish cipher was selected for encrypt/decrypt functions and has been in use for all clients. now a .Net dev was asking me to give him a hand in validating that his .net/c# version is working/matching. he has a quick access point in his code to just encrypt/decrypt the indata value. so we added his test to the selftest for verification. well the first 8 matched but we wanted to determine why the last 8 were not matching to his code. i guess trying to shortcut the testing process was a little short sighted on my part. i will just let it encrypt/decrypt the same string he is testing. Thank you again...

Trying to sync up a .Net implementation of blowfish and was not syncing up so i added to the dcpcrypto for blowfish.selftest i added a new key/data items. the key3, indata3 and outdata3 then copied the code for encrypt/decrypt and then verify the in/out matched. but my data2 is getting stopped at 8 bytes and not the full 16 in the var section. so the EncryptECB is taking it off but i am not sure why. is encryptecb set to only handle 8 bytes/16wide?
