Variable as an integer

Recommended Posts

BigDaddyO

OK,

I'm getting frustrated because this should be so simple yet it's giving me problems.

I'm using a 3rd party tool to create zip files for transfer to USB drives during data migrations. my issue is that I need to create a very simple array to tell the tool how big to make each section of the zip files (in bytes).

$Free = DriveSpaceFree("E:")
$isplitSize = Number(($Free - 10) * 1024 * 1024)
Dim $aFileSizeArray[2] = [$isplitSize, 0]

Really easy right?

except it's not seeing the value in the array. During trouble shooting I did a clipput($isplitSize) and then manually pasted that as the first value in the array and it worked fine. So i can only assume the value of $isplitSize is not being created as a true integer.

Any ideas?

Thanks,

Mike

Why are you using the Number function? DriveSpaceFree returns a floating point number, and Number is used (from what I read) to convert string expressions into numbers.

replace Number with Int:

$isplitSize = Int(($Free - 10) * 1024 * 1024)

i tried number and int. they return a value, that's not the problem.

For some reason when I populate the first value in the array with what is returned, the 3rd party app doesn't see it.

If i populate the first value in the array manually with say, 112056254 it works fine.

Here is an example of how I verified it has something to do with how the variable is being created.

I ran this and then pasted the output into the array manually. I then run the script with the script again, this time with the value manual entered and everything works fine

$Free = DriveSpaceFree("E:")
$isplitSize = Number(($Free - 10) * 1024 * 1024)
;~ Dim $aFileSizeArray[2] = [$isplitSize, 0]
ClipPut($isplitSize)

Dim $aFileSizeArray[2] = [112603136, 0]

ok,

if i do this, it works fine

$iVal = 112603136
Dim $aFileSizeArray[2] = [$iVal, 0]

i'm so confused

Here is the full script I'm using for testing.

as it is right now, if i run it, i get one big zip file that is a little over 300mb, meaning that for some reason it's not seeing the size value in the array.

if I un-remark the line: $isplitSize = 112654123 then I get two files that are 110mb and one that is 82mb

ps. my E: is a 128mb usb drive i'm using for testing. I wanted it small so I didn't have to test with huge files

my D: has mass quantity of free space.

Strange issue. looks like your formula also returns an Int as the commented line does when filling in the number yourself.

I don't have the DLL available so cannot do any other debugging.

lets see if this works.

Took a bit of searching but I found a shareware download and pulled the two needed files from that and it's got the same issues.

The files should be attached to this post.

Must be something with the calculated value.

This seems to work fine:

$isplitSize = number(String(($Free - 10) * 1024 * 1024))

Yep that works for me too...

Weird, so I have to convert the variable to a string in order to convert into a number...

Thanks for the work around Jos.

Its not clear to me as yet why it works and Int() doesn't.

Do you have any description of the Com object, specificly $ObjZip.FileSizeArray ?

I'm fine with the work around but it still makes me wonder if there is some unseen character or something that is being created in the drivespacefree that is creating the issue.

Below is all I got from the manual.

Mike

FileSizeArray Hidden Property

This property contains a VARIANT array representing a FileSize array of unsigned

long values. This FileSize array is used when creating a multi-volume zip file and

writing the individual split files to a hard drive. Each value in the array specifies the

maximum size in bytes that a corresponding split file may occupy. This property is

only used when the MultiVolumeControl property is activated and its

MV_USEMULTI and MV_TOHD bits are set (see page 188).

The first entry in the FileSize array (array element 0) specifies the default split file

size. The default will be used when there is no specific split file size entry in the

FileSize array. The last FileSize array element must be set to 0, which serves as a

terminator for the FileSize array. FileSize array elements 1 through n specify the

maximum size for a corresponding split file 001 through n. It is most efficient to

specify the split file sizes as an integer multiple of 512. Setting sizes below 65536

will result in file segment sizes of 65536 since the smallest compatible multi-volume

file segment allowed is 64K. Common media sizes are defined as follows:

// Common media sizes

#define FSA_FILESIZE360 362496L

#define FSA_FILESIZE720 730112L

#define FSA_FILESIZE1200 1213952L

#define FSA_FILESIZE1440 1457664L

#define FSA_FILESIZE2880 2931712L

Example: The following FileSize array elements would be used to create split files

on the hard drive suitable for storage on 1.44 MB floppy diskettes while reserving 10

KB (10240 bytes) on the first diskette.

FileSize Array Elements:

1457664 element 0

1447424 element 1

0 element 2

If the file created by the zip operation yields 4 split files:

¨ the first split file size would be 1447424 bytes (determined by element 1)

¨ the second and third split file sizes would be 1457664 (the default size specified by element 0)

¨ the fourth split file size would be less than or equal to 1457664 (the default size specified by

element 0)

Used when ActionDZ is set to: ZIP_ADD
