Validating files before upload

[Jose Nilton Pace]

Hi, you can try this in 2 steps. In Object Inspect, set AutoUpload := False;
Put a button to Select file:

Code:

procedure TIWForm1.IWButton1_SelectAsyncClick(Sender: TObject; EventParams: TStringList);
begin
  IWFileUploader.SelectFile;
end;

Another button to upload the file after you tested the name:

Code:

procedure TIWForm1.IWButton2_SelectAsyncClick(Sender: TObject; EventParams: TStringList);
begin
  IWFileUploader.StartUpload;
end;
