ClPathCombine

clPathCombine is a function that is part of the Clomosy library. This function returns a string data by concatenating the file path and file name.

The general usage is as follows:

clPathCombine(FileNameString:WideString; CombinePathString:String);

FileNameString : Searched file name.

CombinePathString : The file path to merge.

For instance:

CombinedPath := clPathCombine('File.txt','C:\Document');
 // Now CombinedPath will be 'C:\Document\File.txt'.

Example:

If the file does not exist in the project directory, it saves the file. If the file exists, it adds a line to it. When the application runs for the first time, it will not find the file, so it will add it to the file path and display a message. When run for the second time, a line is added to the existing file.

Base Syntax

var
  strList:TclStringList;
  fileStr:String;
  i : Integer;
begin
  strList := Clomosy.StringListNew;
  fileStr := clPathCombine('File.Txt',Clomosy.AppFilesPath);

  If clFileExists(fileStr,Clomosy.AppFilesPath) then
  begin
    strList.Add('New Line 1');
    strList.SaveToFile(fileStr,0);
    ShowMessage('A line has been added to the existing file. To check, check your file via the file path. File path:'+#13#10+ fileStr);
  end else
  begin
    strList.SaveToFile(fileStr,0);
    ShowMessage('The file has been added to the directory. Directory path: '+#13#10+ fileStr)
  end
  if strList.Count <= 0 then
     ShowMessage('Empty!');
   else
   begin
     for i := 0 to strList.Count - 1 do
       ShowMessage(Clomosy.StringListItemString(strList,i));
   end;
end;
