Let me tell it that way @programmerdelphi2k, with my posted source I was able to enter "documents" as an included folder-name and "*.pdf" as a file-mask (also "c:\windows" to exclude that folder) and as a result i get all "*.pdf" files that are inside of any "documents" folder. exemplary "c:\users\documents\manual.pdf" or "c:\users\public\documents\another.pdf" or "c:\users\username\documents\etc.pdf" ... How-to with your way?

@Lars Fosdal In first post he tried to search for something, than he wanted a search for specific things, that will my code do.

@programmerdelphi2k I am happy when you are happy. To me your way is useless, you lost what I was needing, finding specific files in specific folders.

Take a guess 😛

program Project12; {$APPTYPE CONSOLE} {$R *.res} uses System.Classes, System.SysUtils; function ContainsString(const AStringList: TStringList; const ASearchFor: string): Boolean; begin Result := (AStringList.IndexOf(ASearchFor) <> -1); end; var sl: TStringList; begin try sl := TStringList.Create; try sl.Sorted := False; sl.Duplicates := dupIgnore; sl.CaseSensitive := True; sl.Add('some'); sl.Add('some.xyz'); WriteLn(ContainsString(sl, 'some')); // True WriteLn(ContainsString(sl, 'Some')); // False WriteLn(ContainsString(sl, 'yxz')); // False finally sl.Free; end; ReadLn; except on E: Exception do Writeln(E.ClassName, ': ', E.Message); end; end.

Does it now works for you? Feel free to remove 🤭

Makes not much sense right now.

Fixed the "Folder must included" thingy, now it works pretty well for me.

"Folder must exist" is currently not working, I will update but not today 😛

Can you retry please @programmerdelphi2k @robertjohns, just replace the full units code with above. Thanks for tipp about SetLength() @programmerdelphi2k, will be added later, in above i put now the exclusions right into the searching job, should be in theory faster now 😛 Ps: Now it is working with a full given pathname for exclusion, eg: "c:\windows"

Please not use a full path at excluding, for that my code ain't designed yet.

function FindEx(const ABasePath: string; const AFoldersMustExist: string = ''; AExludedFolders: string = ''; const AFileMask: string = '*.*'; const AIncludeSubFolders: Boolean = False): TFindArray; var tmp, Folders, Files: TFindArray; splitIncluded, splitExcluded: TFindArray; i, ii: Integer; begin SetLength(tmp, 0); SetLength(Folders, 0); SetLength(Files, 0); SetLength(splitIncluded, 0); SetLength(splitExcluded, 0); if (Length(AFoldersMustExist) > 0) then begin if (0 <> Pos(';', AFoldersMustExist)) then splitIncluded := AFoldersMustExist.Split([';']) else AddStrArr(splitIncluded, AFoldersMustExist); end; if (Length(AExludedFolders) > 0) then begin if (0 <> Pos(';', AExludedFolders)) then splitExcluded := AExludedFolders.Split([';']) else AddStrArr(splitExcluded, AExludedFolders); end; // collect folder(s) to work on if AIncludeSubFolders then tmp := FindExFolders(ABasePath, AIncludeSubFolders) else AddStrArr(tmp, ABasePath); // sieve out folders that match criteria if (Length(splitIncluded) > 0) then begin for i := Low(tmp) to High(tmp) do for ii := Low(splitIncluded) to High(splitIncluded) do if (0 <> Pos(UpperCase(splitIncluded[ii]), UpperCase(tmp[i]))) then AddStrArr(Folders, tmp[i]); end else Folders := tmp; // remove unwanted folders from search if (Length(splitExcluded) > 0) then for i := High(Folders) downto Low(Folders) do for ii := Low(splitExcluded) to High(splitExcluded) do if (0 <> Pos(PathDelim + UpperCase(splitExcluded[ii]), UpperCase(Folders[i]))) then Delete(Folders, i, 1); SetLength(tmp, 0); // get files that matching the criteria for i := Low(Folders) to High(Folders) do begin if (Length(AFileMask) > 0) then tmp := FindExFiles(Folders[i], AFileMask) // do not enable the IncludeSubFolders switch here (!) else tmp := FindExFiles(Folders[i]); for ii := Low(tmp) to High(tmp) do AddStrArr(Files, tmp[ii]); end; Result := Files; SetLength(tmp, 0); SetLength(Folders, 0); SetLength(Files, 0); end; I apology, please update that method like shown above and now it really should work, I've not tested it much with extra large filesystems, on a small one it works like it should. You can enter "Windows" or "windows" or just "win", everything that has this in name will be excluded from the deeper file search mechanism. When I got more free time I will continue making it better.

Please compare with my approach, I posted earlier a full demo app that works straight out of the box, would like to see time results and if my way would also benefit of a full exclusion from giving names.

Yes, it was very complicated to fix. Uploaded a fully working Demo application based on my above mentioned code, added "Exclude" capabilities as you wanted. FindEx.zip

It should be easy to adapt any different kind of specifications, like excluding a defined folder. Enjoy!

All of that is not needed, just do it in the Object Inspector like I told.

Just create first column without caption and set its width to 0. The others do what you want to do.

How about using an ImageViewer control, put your bitmap in and give the control the "BestFit" property.

Welcome to forum! I am no clairvoyant and I assume nobody here is. So without showing anything how you do, what you think we can say? Watch line 123 there at call xyz you did something wrong?! Best practice would be a small demo zipped that shows us what you do and how you try to achieve that.

Delphi 11 Community Edition based on 11.3.1 Pro

Delphi version 1 had no FMX and would probably not run under Windows 11 at all. (16bit)

That "double don't" mean you do use Delphi for that, right?

Pascal is dead - long live pascal!
