VS 2008 Append Bits For A Very Simple Encryption?
Sep 22, 2010This seems like it would be so simple and fast, but I cannot figure out how to accomplish it in VB since there aren't many bit functions. I want to take a file and append 5 junk bits at the beginning and 3 junk bits at the end. In essence, just add 1 byte to the file, but in the process offset all the current bits so the file is no longer readable.
I just need a very simple encryption/decryption, but it needs to be very fast as well. I try XORing the bytes, but it gets slow with just a 1MB file. Some of the files are going to be close to 10MB.

VS 2008 - Append Now Time Part To Date Variable
Jan 11, 2010I'm working on a small accounting app. I have a query to show transactions with a running balance.
SELECT transactionid, transactiondatetime,
amount,
(SELECT SUM(amount)
FROM dbo.transactions as D1
WHERE D1.transactiondatetime <= D0.transactiondatetime) AS balance
FROM dbo.transactions AS D0
I capture a gamesheet for a certain week. so if I select a date on a monthcalendar the sheet applies to the weeknumber of the selected date. When I save transactions I take the date at the last day of that week as the transactiondate. I need to store a datetime though because my query works of the datetime to get an accurate running balance. How can I append now() time part to my date variable and then store that in a datetime variable to get a transactiondatetime.
Here is my code for getting a transactiondate:
Dim dt As New Date
dt = Me.MonthCalendar1.SelectionStart
'get last date of week. Friday
Dim tdate As Date = dt.AddDays(5 - CInt(dt.DayOfWeek))

.Net Linq - How To Append A Where Clause
Apr 23, 2009Pretty new to VB.Net. Having a bit of trouble here with something I though should be simple.Keeping it simple. Let's say i have a Document table with "Name" that I want to search on (in reality there are several other tables, joins, etc ..). I need to be able to build the query where clause based on string values passed in.
Example - user may pass in "ABC" or "ABC DEF" or "ABC DEF GHI".The final query would be (syntax not correct i know)Select * from Documents Where Name Like %ABC% AND Name Like %DEF% AND Name like %GHI%
So, I though I could do something like this.
Dim query = From document In _context.Documents
<< loop based on number of strings passed in >>
query = query.Where( ... what goes here?? )
For some reason, being brain dead or something, I can't figure out how to make this work in VB.Net, or if I'm doing it correctly.

Append An Element To A List?
Dec 15, 2011I am new to Vb.net so I will need some handholding. I have been searching everywhere but can't find what I need.I'm creating an app that has two forms.Each form has two comboboxes.The comboboxes are populated via a list and the list is populated by reading a text file for each combobox.The second form is called from the main form to modify the entries in the comboboxes. When I select the displaymember in the combobox a value corresponding to that entry is displayed in the text box.Now here is what I need.
I need to be able to append new values to the list so when focus is returned to the main form the new value is present. I'm using a combobox and a textbox on the second form as the import.The combobox is used to either select a present value to be able to modify the value in the textbox, or is used to add a new list element.

Append Text To A Textbox VB?
Jul 12, 2011I am attempting to append information to a textbox in VB. My app allows the user to choose a variety of options and displays all the information in a single, read-only text box.
I would like to set it up so every time an event triggers something to be written in the text box, it gets appended instead of overwriting the text currently in the box.
The only constraint is that text should be appended as a new line, not directly after the last sentence.
