VS 2008 - Read A 16bit Binary File (tif Image) And Pixel Values Of The Image Ranges From 1200 To 4500 - EndOfStreamException Unhandled Error

Mar 18, 2012

I am trying to read a 16bit binary file (tif image) and pixel values of the image ranges from 1200 to 4500. I tried to use BinaryReader using ReadUInt16 but I get EndOfStreamException Unhandled error. ReadByte method works fine with an 8bit tif file. I do not know how to read a 16bit image file using binaryReader. Shouldn't I use ReadUInt16 since values of pixels range from 1200 to 4500?

Convert Image To Binary Text ?

Jul 22, 2011

converting an image file into binary text in VB 2010.I am working on a compression program and need to see the actual binary as text. I have code for converting text files to binary and it works fine but, need to attempt files with greater randomness that are typically uncompressable.(JPG's) I understand that the file conversions may be huge. I plan on manipulating the binary in smaller manageable chunks.

Interface And Graphics :: Evaluate Pixels Within A Binary Image?

Aug 18, 2008

How can I evaluate pixels within a Binary Image?What I have done so far is to take the image and use it's "getPixel" method and do a comparison of this pixel to black/white. But that can't be right... Can it? It's a binary image, I should be evaluating each pixel as true/false. 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
