DOS File Lookup control template
You can specify the file masks, the default directory and filename, and the variable to receive the filename selected by the end user.
In addition, you may optionally allow the selection of multiple files and specify the code to process each selected file. The template generates a LOOP to process all the selected files.
The DOSFileLookup template provides the following prompts:
General
File Dialog Header
| Type the text for the caption of the Windows file dialog.
| DOS Filename Variable
| Press the ellipsis (...) button to choose a variable to receive the end user's choice from the File Schematic dialog. You can also type the variable name directly into the entry box.
| Default Directory
| Specify the starting directory for the Windows file dialog. If blank, the file dialog opens to the working directory.
| Default Filename
| Specify the initial filename for the Windows file dialog. If blank, the file dialog opens with no intial filename.
| Return to original directory when done
| Check this box to reset the working directory to its value prior to the file lookup.
| Multi-Select?
| Check this box to allow selection of one or more files.
| Action For Each Selection
| Type a valid Clarion language statement to execute for each selected file--typically a procedure call. You may want to pass the FileName Variable
The template generates a LOOP to execute the code you specify for each selected file. The generated code reloads the FileName Variable with the appropriate filename for each loop cycle.
