|GUI ScreenIO for Windows|
This API displays the standard Windows Open dialog used to select the drive, directory, and name of a file (or set of files) to open.
To select folders (directories) instead of files see BrowseForFolder.
No issues; this API will behave as if it were running locally on the client.
Files available to copy to your system:
Specifies the text that will be displayed in the title bar of the open dialog when it is displayed.
Null-terminated default file extension to use, for example:
A combination of bit flags that specify various options used to initialize the common dialog. The most useful ones are:
You OR these values to specify the bit values used for OPENSAVE-FLAGS. You can ADD them together, but you must be certain that the addition does not result in a carry, which would not set the desired bits.
You assign these values like this:
OFN-EXPLORER PIC 9(9) COMP-5 VALUE H'080000'.
|OFN-ALLOWMULTISELECT||000200h||Allows the user to select more than one file.|
|OFN-CREATEPROMPT||002000h||If the user specifies a file that doesn't exist, prompt the user for permission to create the file.|
|OFN-EXPLORER||080000h||Specifies the use of new Explorer-style customization methods. Required if you specify OFN-ALLOWMULTISELECT.|
|OFN-EXTENSIONDIFFERENT||000400h||Allows the user to specify a file extension other than the default extension.|
|OFN-FILEMUSTEXIST||001000h||Specifies the user can only type names of existing files in
the File Name field.
|OFN-HIDEREADONLY||000004h||Hides the Read Only checkbox.|
|OFN-NOCHANGEDIR||000008h||Restores the current directory to its original value if the user changed it while searching for a file.|
|OFN-NODEREFERENCELINKS||100000h||Directs the API to return the path and file name of the selected shortcut (.LNK) file. Otherwise, it will return the path and filename of the file referenced by the shortcut.|
|OFN-NONETWORKBUTTON||020000h||Hides and disables the Network button.|
|OFN-NOREADONLYRETURN||008000h||Prevents selection of read-only files, or files in a read-only subdirectory.|
|OFN-NOTESTFILECREATE||010000h||Specifies that the file is not created before the dialog is closed. Not recommended, because then your application must ensure that the file selected is not read-only.|
|OFN-NOVALIDATE||000100h||Allows invalid characters in the filename.|
|OFN-OVERWRITEPROMPT||000002h||Causes the SaveAs dialog to generate a message box if the selected file already exists, and allows the user to confirm whether to overwrite the file.|
|OFN-PATHMUSTEXIST||000800h||Restricts the user to valid paths and filenames.|
|OFN-READONLY||000001h||Causes the Read Only checkbox to be selected when the dialog is initially displayed.|
|OFN-SHAREAWARE||004000h||Ignore sharing violations when returning a filename.|
Handle of the owner window; panel-HWND.
Specifies the length of the custom filter.
Specifies the index of the current filter in OPENSAVE-FILTER:
MOVE 1 TO OPENSAVE-FILTER-INDEX.
Specifies the length of OPENSAVE-FILESPEC:
MOVE LENGTH OF OPENSAVE-FILESPEC
Specifies the length of OPENSAVE-FILENAME:
MOVE LENGTH OF OPENSAVE-FILENAME
Specifies the zero-based offset from the beginning of the path to the filename in OPENSAVE-FILESPEC. For example, if the filespec is the string:
this variable will contain the value 13.
Specifies the zero-based offset from the beginning of the path to the file extension OPENSAVE-FILESPEC. For example, if the filespec is the string:
this variable will contain the value 18.
Initial directory that is displayed:
Contains pairs of null-terminated strings specifying the available filters. The first element is the name of the filter, and the second element is the filter pattern.
The filter is terminated with two nulls:
STRING 'Application Profiles (*.INI)'
Not used; must be LOW-VALUE.
Upon return, contains the full path and filespec, followed by a LOW-VALUE.
Filename and extension, less the path, used to initialize the File Name edit control. This must be LOW-VALUE if initialization is unnecessary.
Upon return, contains the full path and filespec of the selected file.
This argument is standard for all CALLs to GSWINAPI. It is used to select the desired API or function, and to return the status of the operation.
Used to return the status of a call to GSWINAPI. A value of zero is a failure, any other value indicates success.
Recommended usage is to test the 88-level value WIN32API to see if it worked, then to use the text error message to see why it failed.
* ------------------------: If function failed,
Error code that was returned by Windows. This is not generally useful unless you have the Windows Platform SDK documentation available to you.
Plain-text error message that describes why the operation failed.
The number of these present varies depending on how many arguments are used by the desired function. These are not used, but must be present because this CALL requires seven arguments.
