I am working with delphi, I want a list of all files of a directory when I execute openpicturedialog.
i.e., When open dialog is executed and i select one file from it, I want the list of all files from the directory of selected file.
You can even suggest me for getting directory name from FileName
property of TOpenDialog
Thank You.
@Himadri, the primary objective of the OpenPictureDialog is not select an directory, anyway if you are using this dialog with another purpose you can try this code.
Var
Path : String;
SR : TSearchRec;
DirList : TStrings;
begin
if OpenPictureDialog1.Execute then
begin
Path:=ExtractFileDir(OpenPictureDialog1.FileName); //Get the path of the selected file
DirList:=TStringList.Create;
try
if FindFirst(Path + '*.*', faArchive, SR) = 0 then
begin
repeat
DirList.Add(SR.Name); //Fill the list
until FindNext(SR) <> 0;
FindClose(SR);
end;
//do your stuff
finally
DirList.Free;
end;
end;
end;
if you use delphi 2010 then you can use tdirectory.getfiles first add ioutils.pas to uses clause then write the following line of code in the event handler(in addition to code you already have in that event handler)
uses IOUtils;
var
path : string;
begin
for Path in TDirectory.GetFiles(OpenPictureDialog1.filename) do
Listbox1.Items.Add(Path);{assuming OpenPictureDialog1 is the name you gave to your OpenPictureDialog control}
end;
Change the filter property in your OpenPictureDialog to include all files:
All (*.*)
Edit: I don't think you can select a directory in a Open(Picture)Dialog, it surely isn't the purpose of an OpenPictureDialog anyway. Perhaps this is what you seek.
Then use FindFirst and FindNext to get the files in this dir.
You can use extractFilePath function to get the directory name:
myPath := extractFilePath(FileName);
where FileName is name of file you choose by OpenDialog.
if OpenPictureDialog1.Execute then
FileListBox1.Directory := extractFilePath(OpenPictureDialog1.FileName);
You can also use a FilterComboBox linked to FileListBox to filter the file type.
TFileListBox and TFilterComboBox are in the tool palette under "Win 3.1". From Delphi 4 there are these objects.
