Delphi ShellExecute?

Question

Delphi

In general, the main application launches the Project1.exe program that is located in the control folder using the method:

...
ShellExecute(Handle, 'open', 'control\Project1.exe', nil, nil, SW_HIDE);
...

In turn, Project1.exe is written to open a file that is located in the same place as it is.

If you run the Project1.exe application directly, then everything works. Well, if you run it from the main application, which is higher than the level, then an error occurs (does not find the file).

You can get by in Project1.exe by writing an absolute path relative to the main application control/file.txt but is this correct? Again, if you run it directly, then naturally it will not find it. An absolute path relative to disks is also not an option.

Answer 1

You need to specify the working directory when starting with shellexecute

Answer 2

IncludeTrailingPathDelimiter(ExtractFilePath(ParamStr(0))) + 'относительный путь до файла'
