# Conversion From Binary?

Jun 29, 2009

I am writing lots of numbers to a binary file, using the "My.Computer.FileSystem.WriteAllBytes" method. I'm struggling with reading the numbers back in....

Code:
Private Sub trial()
Dim vals1() As Byte
Dim vals2() As Byte

[Code].....

How do I know where one ends and the next begins? This is especially important because the length of vals could be something other than 8....

## SQL Server Binary -> DataTable -> SQL Server Binary Conversion ?

## Decimal To Binary Conversion?

Mar 6, 2010

I write a program to convert Decimal numbers to Binary numbers. It is working well. But I want to control the bits. i.e - We can write 31 as a) 11111 or b) 011111. When I run my program it displays 11111. I want to take input bit from a text box and display it like 0011111 or 011111 or what ever bit I input. How can I do that ?

Private Sub DecToBin()
Dim i As Integer = txtDec.Text
Dim binary As String = Convert.ToString(i, 2)
txtBin.Text = binary
End Sub

## Text -> Excel Conversion (with Extensive Formatting Required After Conversion)?

May 11, 2012

I'm creating a program in VB.net that does the following:At a high level I receive a file in email, put the attachment in a monitored folder, import the text file to excel, format the excel, and then email the excel file to a list of recipients.

Here is my plan:

Completed: Outlook VBA to monitor all incoming email for specific message. Once message is received drop attached .txt file in a specific network folder.

Completed: (VB.net) Monitor folder, when text file is added begin processing

Not Complete: (VB.net) Import text file to Excel

Not Complete: (VB.net) Format Excel Text file.(add in a row of data,format column headers with color/size, add some blank columns, add data validation to some of the blank columns that allow drop down selections)

Completed: (VB.net) Save file.

Completed: (VB.net) Send file to list of recipients.

Obviously the items above that are not complete are the bulk of the work, but I wanted to get some advice on what some of you think would be the best way to approach something like this. The import and formatting of the file are causing me some problems because I just can't decide what would be the most efficient way to do this.

The way stated above. Import to excel -> format Having a template excel that contains all of the formatting already done for me and attempting to transition the data to this document (no clue if/how I can do this). Is it even feasible? Have the template already created and then import the text file to a new excel file, then transition that data to the excel template?

Something I thought about, in terms of formatting the document, was to record a macro of me doing all of the formatting that I'm going to need and then attempt to convert that macro into my vb.net code, but I'm not sure if that will work. I will need to verify that the text file comes in the EXACT format every time correct?

## C# - Write Binary Data "as Is" To Registry (visible Binary Data As String From Regedit Only)

Feb 23, 2011

I have been googling this and have not come along a working solution for an entire day. I don't know anything about binary data types (as I've never knowingly used them) and I'm trying to write a binary value that I see in the registry, to the registry. Now, all I see is the following [shown below]... and if I try to pass that as a string to the RegSetValueEx in the WinAPI and of course it errors out...

I do not know what 'numbers' I need to pass into the lpData As Any, argument of RegSetValueEx (i tried a bit array) in order for it to come out as the following [shown below] in the regedit. I really have no idea, and my tests to place random numbers in the bit array just produce corresponding random "figures" as visible in regedit that I do not understand how to 'tie' them together logically. here is the culprit!

## Binary C0 And C1 Control Codes?

Aug 2, 2011

I need to be able to write data to a binary file. No problem - I have a test app I've knocked up that reads and writes to them fine, however the format uses C0 and C1 control codes, and I have no idea how to write them properly. The SOH, ENQ, DLE, NUL type of thing. I'd post some but they are non-printing. I know what they mean and what they do but have no idea how to write them.Basically we are writing our own system that generates test data files for import by another program. My files that I write have the correct number of fields and correct value and formats but because I can't get the tags to write they data is imported incorrectly. I've spent days reading up on it but can't find what I'm looking for.Not dealt with binary data files in VB before so this is all new.

## Binary Files And Backgrounworker?

Nov 27, 2009

I used backgroundworker to receive file segments from a server, it taking the segments and save them directly to a binary file. the problem is,I using a global variable to store the "FreeFile()" number.when "backgroundworker" receive "START" it do F = FreeFile()

when it receive "Segment", it should append to that file, but the problem is ... backgroundworker no more recognize the file (which its identifier saved in global variable F) and telling "Bad File"?!

whats the soultion?I think about opening the file and close it each time (not leave the connection to the file available). But I didn't figure out how to append to Binary files, It always replace their contents. and If I use "Append" option it corrupt the file!

## Binary Search Not Using An Array?

Apr 11, 2011

I am trying to write a program which performs a binary search. The user will input the name of a state in a textbox.I have a listbox which is populated with the 50 states in ABC order.The middle of the list must be determined and then determine which half of the list the state may be located. If the middle item is less than the state name the state should be in the second half of the list. If it's greater than the state name is should be in the first half of the list. The calculation for looking at the middle itemi the list is:

middle = CInt(first + last)/2)

There is a variable 'flag' which is initially set to false and then will be set to true if the state name is found. The variable first is initially set to 0 and last needs to be set to one less than the number of items in the list.Below is a very rough program fragment.

Code:
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
Dim i As Integer
Dim flag As Boolean = False
Dim first As Double = 0
