FILE SIZE

[wxperson99]

I looked at a past post and saw some sample code from Francisco which determines the size of a file.

I am getting an error...

Unable to load plug-in library. Please rebuild you project and make sure all required plug-ins are installed... Action skilled.

What am I doing wrong?

I can only suppose that you missed to install the "Call DLL Function" plugin.

Regards

[wxperson99]

I have DLL calls in other installation projects and they work fine.

Is the DLL function installed by project?

[wxperson99]

ACTUALLY I have some CALL DLL function code within this same project.... and it works... so something it weird

works

~~mIDEFunc.dll\mEXEFunc.dll~~

does not.

Ideas?

[FrancescoT]

Do you have any chance to send me a very very minimal project that replicates the issue?

Regards

[wxperson99]

I just created a blank install with just the code I copied from the article on file size. It is small so I just pasted it below. You would have to change the file being examined. Thx... George

I'll let you know!

[wxperson99]

OK..

I have tried this on several PC workstations with the same resulting error... and I really need a way to determine file size pretty badly.

THanks,

George

[FrancescoT]

Dear George,

I have been able to replicate the error you reported, but it looks a very strange error.
I am able to call other functions from the same "kernel32.dll" or to call very complex functions from my custom dlls, but it fails using a similar call to "CreateFile" WINAPI.

I need more time to work on this.

Regards

[wxperson99]

Glad you see it too

I see the same behavior as you.

Let me know when you have figured it out.

[FrancescoT]

Dear George,

try this (just copy and past the following IA Clipboard Data in your script).

NOTE! The code assumes the existence of the "c:\test\myfile.png" file.

Code: Select all

This works!
The problem you had was caused by some wrong parameters passed to the "CreateFileA" WINAPI.

[wxperson99]

I keep getting a -1 return on the FILE_HANDLE.

The FILE_TO OPEN file does exist. I tried several different file names...

Dear George,

honestly I cannot be sure on how you used my code. Due of this, attached you find a small project that demonstrates the various WINAPI calls.
To avoid any possible error, the sample also creates a target directory with a small TXT file.

However due the fact that the "GetFileSize" may also return the "high-order doubleword of the file size" with its second parameter, it may be difficult to handle the file size properly via script. In addition MSDN recommends to use "GetFileSizeEx" in place of "GetFileSize", where a Large Integer is used to return the size value.

That said it may be preferable to release a custom DLL at such purpose.

Hope this helps you.

Regards

Hi,

Over the weekend I wrote a small program that writes a file's size to a text file.

I am running that inside my script and reading the results into a variable.

Easier than trying to figure the DLL thing out.

Thanks,

George

George,

I have a plugin I wrote a while ago to get a file's size. I think I stopped coding it when I think there were other solutions to the same problem. If you're quite happy that doing it via a DLL call was the only way you see it working I'll be happy to look at it quickly and see if I can finish it off and test it and then add it here for you to use. Then again, it seems you "solved" the problem using an external file so perhaps you don't need a plugin? Let me know your thoughts on the matter before I commit any time to what might be a one-off problem.
