Hello


Was wondering if anyone managed to do a descent File transfer application Client/server using either VDSINET.DLL or VDSIPP.DLL?

It seems to work properly with text files, but with binaries I'm out of luck.

If someone did one could you tell me what DLL you used and any tips you might want to share. Thanks...

Hi Marty,
I've used both but only for clients doing FTP. I do recall a "transfermode" option for VDSIPP for asacii or binary. How are you transfering the files?

What I want to do is to transfer a binary file from one IP adress to another thru VDS only, not with FTP. Because FTP Server functionnalities is not supported in VDSIPP.DLL

There's was a code example a while ago to create a client and server using VDSINET.DLL.

Here's the thread to understand what I mean...

Using that code on my Win2K to send a binary file doesnt work well at all. The file isnt transfered complety or gives a netsoket error. And its slow too.

Ok Marty,
After reviewing the code from that thread these are the things I would check.

1) Setting the position for the split may be incorrect
2) The split is exceeding the 32K limit of VDSINOUT
3) The split is too small and the transfer is bumping into itself. The limit for VDSINOUT is 32K I think. This example shows a split for 256 bytes this might slow down the transfer and possibly cause writting problems.
4) If for some reason you use readc/writc instead of readb/writb you will lose the null chars

I would try transfering a file containing a series of consecutive numbers like this:

1
2
3
4
5
6
7
.
.
32767

see where data gets lost.
Sorry I can't give you more detail but I hope this helps .

Ahhh.. Thanks a lot! That's very helpfull!

I will look into the code and try tweaking the code...

This is similar to what I want to do... however, I was wondering if this can be done without a server using Windows shares.

For example, I want to have a folder that is shared on a LAN, and have my VDS app check the folder for updated files. If it finds that there are updated files, it would retrieve the newer files and replace the old ones.

Can this be done without using HTTP, FTP, etc. and without mapping the share to a drive letter?

On a plain LAN you should be able to copy files from a computer in the same workgroup
without mapping to new drive letters etc.

Try something like this:

Hiya Dread,

I didn't know that...

All my drives are shared on all computers.

Other VDS commands should be able to work like this too, such as:
