For the past day or so, I have been trying to compare values in my SQL server against an actual calendar. I have had mixed luck with this and I have exhausted my limited knowledge. I am looking for a shove in the right direction.
Background:Right now, I have a program that writes a record to a database when the program completes successfully. This time stamp has both the date and time on the SQL box. I want to grab that information and compare it against the basic calendar. I have attached a picture that should help explain things. This is just my test app,

I'm trying to make this program which compares the difference between any date in the past and the system date, showing how many days have elapsed since that date. This is the layout I've created so far, the two date boxes currently show the system date so even if I change the system date, both those boxes will adjust to show it as well. I want to try and make the system date a box without a drop down arrow and so you cannot edit the box at all. The box below is fine how it is as the user can enter any date they desire. And the text box at the bottom needs to show the difference between the system date and the inputted date.

View 1 RepliesI have to create a new program that reads to Text files. These text files are in the form of a report (with column headings). The purpose is to compare each record line by line to see if their have been any changes made. The record is based on an Account#. Over time these files will be considerably large. What is the best way to do compare records from each file. I'm thinking loading each file into an array and processing them that way.

View 3 RepliesI have 2 Text Boxes containing lists of names and I have a 3rd text box which I would like to use to determine the names that are missing from textbox2 that are listed in textbox1.
Textbox1 is: Customer
Textbox2 is: Closed Sale
Textbox3: is Sale not finalized
Would be great if it could auto populate into textbox 3 if not I will just use a button to action the function. First crack at dabbling with VB and whilst googling has managed to aid me in many ways unfortunately sometimes it is difficult to find relevant threads.
Does any one know how I can compare the numeric value of a text box on my Visual Basic 2008 form to the values in a particular column of a SQL database table? Things seem to work fine with bound controls when there are related records in the child table, but if a value is selected that has no related child records the form continues to display old information from the last record viewed. I would prefer to have the fields on the form go blank.

I am trying to use the Boot log and I really don't have much experience with parsing and comparing. What I need to do is to get only the minutes and seconds time stamp from a string similar to this from the boot log
Did not load driver SystemRootSystem32DRIVERSsrv.sys
Loaded driver SystemRootsystem32DRIVERSMpNWMon.sys
Microsoft (R) Windows (R) Version 6.1 (Build 7600)
4 11 2010 23:40:47.375
Loaded driver SystemRootsystem32
tkrnlpa.exe
Next once I get the minutes and seconds subtract 5 seconds
Next compare the resulting minutes and seconds to the minutes and seconds from a second file and display the result
EXAMPLE: If you take the minutes and seconds from above 40:47 - 5 = 40:42.
Next you get the minutes and seconds from the second file and you get 40:59
So you wind up with 40:59 - 40:42 = 00:17

This is the code I have in one button and I have 2 listboxes that will be filled with the info it gets.This code should compare 1 avi file to one jpg file and see if they have the same name. If YES then it will add the avi path to one listbox. If they don't have the same name OR the .jpg doesn't exists it will add avi path to another listbox.. But currently it is adding the avi name to both listboxes.

I'm using Visual Studio .Net 2008 on Vista. The goal of my program is to watch a directory, get file information, then sort them by thier date, and produce a updated text file. I can't seem to get my code to generate a list of files sorted by date. The code does produce a general list of files, however presently ordered in the directory. I also tried an alternate way of sorting the files by date by creating a string, removing the date using substring, then comparing the file dates using datetime.parse but it produces a exception error.

If I select December 2010 I should get the folllowing
startdate = 2010-12-05
enddate = 2010-12-31

Should I subtract dates? How can I get the start and enddate for the current month/year based on the overall start and end date.I'm coding in vb.net.
