getFileCount

val = getFileCount ( [ string Path ="*.*" ] )

Returns the number of files whose names match a specified condition.

Parameters

Path

A string that contains a target file specification. May include the path to a folder and wildcards. If the path is omitted, the default directory will be used. See setCurDir for more details.

Default value: "*.*"

Return value

The number of files matching the specified condition.

Error flags

ERR_OK

The flag set if successful.

ERR_FAILED

The flag set if failed.

Remark

The specified path should comply with the standard notations for directory names in Windows operating system. When you use the optional backslash character (\) in paths, you must place two backslashes (\\) in a string to represent a single backslash (\). If the drive letter is omitted in Path, the default directory will be used as a reference.

The following code returns the number of files in the sample folder that have a suffix between 10 and 19 :

setCurDir("samples")

count=getFileCount("*.1?.iwd")

The following code waits for an image file to appear in a folder to start processing it:

fMask="*.iwd"

setCurDir("c:\\images")

do

'wait for image

while getFileCount(fMask)=0

wait(10)

wend

'process

fName=getFileName(1, fMask)

print fName

loadIm(1, fName)

'remove from queue

delFile(fName)
