BrowserDlgVerifyDownloadSize Function

Action

Adds a download command to the dialog command storage that checks the size of the downloaded file. The file to be downloaded must be declared beforehand with the BrowserDlgVerifyDownloadSize function. The function must be called before the download starts. Multiple verifications can be applied to a single download command to ensure that the resulting file size lies in between certain bounds. During recording, you can add a BrowserDlgVerifyDownloadSize function by checking the Verify size of download checkbox in the save file dialog.

注: This function only works with Internet Explorer.

Syntax

BrowserDlgVerifyDownloadSize( in uExpectedSize : number,
                              in nOptions      : number optional := VERIFY_SIZE_EQUAL,
                              in nSeverity     : number optional := SEVERITY_ERROR      ): boolean;

Return value

true if successful
false otherwise

Parameter	Description
uExpectedSize	The file size used for the verification
nOptions	Describes how the actual size is compared to the expected size: VERIFY_SIZE_EQUAL VERIFY_SIZE_LARGER_THAN VERIFY_SIZE_SMALLER_THAN If this parameter is omitted, a check for equality is performed.
nSeverity	Optional: Severity of the error that is raised if the verification fails. Can be one of the following values: SEVERITY_SUCCESS: Success; no error (numerical value: 0) SEVERITY_INFORMATIONAL: Informational; no error (numerical value: 1) SEVERITY_WARNING: Warning; no error (numerical value: 2) SEVERITY_ERROR: (Default) Error; simulation continues (numerical value: 3) SEVERITY_TRANS_EXIT: Error; the active transaction is aborted (numerical value: 4) SEVERITY_PROCESS_EXIT: Error; the simulation is aborted (numerical value: 5)
