Parameters
| Parameter |
Data Type |
Description |
| pFile |
CSTRING(260) |
Full path to the executable file to run. |
| pParams |
CSTRING(260) |
Optional command-line parameters to pass to the executable. |
| pWork |
CSTRING(260) |
Optional working directory for the executable. |
| ShowCmd |

Returns
A LONG value indicating the result:
- 1 if the file launched successfully
- 0 if the launch failed
- Negative values may indicate a Windows shell error
Example
FilePath CSTRING(260)
Params CSTRING(260)
WorkFolder CSTRING(260)
ShowCmd LONG
Ret LONG
FilePath = 'C:\Windows\Notepad.exe'
Params = 'MyDoc.txt'
WorkFolder = ''
ShowCmd = 1 ! SW_SHOWNORMAL
Ret = vuRunEx(FilePath, Params, WorkFolder, ShowCmd)
MESSAGE('vuRunEx returned: ' & FORMAT(Ret), 'vuRunEx Test')
Notes
vuRunEx is generally the preferred choice when you need to launch an executable with parameters.pFile and pParams are passed separately, which avoids command-line formatting mistakes common with single-string launch functions.- If
pWork is blank, the system default working folder is used.
- Use
vuRunExWait when you need the same explicit parameter handling plus optional wait behavior.
