I am converting a VB6 WebClass application to VB.Net. Used the VB upgrade
tool to do the conversion - and it left me a lot of little code things to
do. Did those code things and got my app to compile. Did a few other code
things to take advantage of .Net features not available in VB6.
When I start the application on my PC I get the error shown below. It seems
to me that the app initiation is failing before any app code is executed.

I am implementing dup file finder via getting Hash (MD5 or SHA1) from files.
I know how to get Hash but my problem is files are big. Real big (~3-4G
each). That is lot of read from HDD if I am doing a match with even 20
files.
My solution is to get hash from few MB of each file (e.g. first 10MB). At
least it reduces lots of read and time. It does the job but is not a sure
shot way because it is not 'really' the true hash of a file. Thus...

This inquiry may either turn out to be about the suitability of the
SHA-1 (160 bit digest) for file identification, the sha function in
Python ... or about some error in my script. Any insight appreciated

Hi,
I am very new to C# and NET framework. I am trying to hash (using
MD5CryptoServiceProvider) a source that is split into several files.
Now when the source is in one file I can produce the correct md5 hash.
My issue is how can I reproduce the correct hash when the file is split
into different files.

I'm wondering (and hoping that somebody will be able to answer this):
If I calculate the hash value of files (either MD5 or SHA1), can I then be
sure that:
1) Two files with the same hash value are in fact identical?
2) Two different files will NEVER have the same hash value?
3) If two files have the same MD5 hash value, they will ALSO have the same

I'm having difficulty trying to figure out how to print a text file from a hash table one line at a time. I have the text file read into the hash table and can print the text file all at once, but I can't seem to figure out how to do it one line at a time.
Here is what I'm trying to do: I want the user to be able to print the text file one line at a time by clicking a button to see the next line.

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
Here is my compilation command:
