AppName
Function AppName : string
Example
procedure ScriptEvent(var Value: variant);
begin
Value := AppName;
end;
Usage
AppName returns the filename, including extension, of the Velox host executable running the script.
Additional Technical Info
AppName returns the filename of the executable hosting the current Velox process, including its extension—for example, Velox.exe, VeloxService.exe or VeloxAPIService.exe.
Implementation
During vxConfigPath unit initialization, Velox evaluates ExtractFileName(ParamStr(0)) and stores the result in gAppName. Every script call returns that cached string under the process-wide path critical section. The value cannot change during the process lifetime and does not inspect the filesystem on each call.
This is a process identity hint, not a stable product-edition identifier or security assertion. The filename may be renamed by deployment, can differ between Designer and services, and should not be used to authorize work. Use it for diagnostics or carefully defined host-specific branching only; configuration is generally preferable to executable-name tests.
The value contains no directory. Use AppPath for the executable directory or AppTitle for the cached name without its final extension.
