Is it possible to write a binary file directly to the clipboard in .NET? (Rather than write it to a file and then copy it?) the file is not an executable but will be pasted to the desktopfolder for example. [Code]

my goal is to obtain the OCR directly from a image stored in the Clipboard... but everything I write in the miDoc.Create(Clipboard......) code I receive the message that it's not a String what to write instead of ("c:example.tif") to read the image directly from the Clipboard?
I'm trying to "convert" an Access DB to a stand alone application. I have under estimated the differences between VBA and VB. Although I have many questions, I'll focus on this topic first.
The Access DB collects and maintains SNMP traps from a radio station. I import CSV files from a remote Unix server via FTP, parse the text line-by-line, and add to a table as a new record. So far, I can parse the text and add to a dataset but I want to write directly to the data source. I also need error handling that will trap errors for duplicate records. There is a Reconcile function that ensures that all lines in the CSV files are added to the table before the files are permanently deleted. Here's what I have so far:
Public Class clsRnm
Private msTrapTable As String
Private moTrap As clsRnmTrap

I need it as a byte array to do some processing in between.

Im trying to read and write to a file in binary.to give an example of what im trying to do i have posted a picture below.the string is 12 bytes long and each four bytes has a float.the one in red is set at 1 and green and blue are 0 giving the read as the overall color. i have been trying to get this well i tried once and gave up but its been awhile.i have this so far but it doesnt work. this is kinda what i got to read the bytes out but its messed for i have been trying everything i could think of
Code:
Dim s1 As FileStream Dim br As BinaryReader s1 = New FileStream(Application.StartupPath & "/files/test1.bin", FileMode.Open, FileAccess.Read) br = New BinaryReader(s1) Dim bytes(12)

I want to write a string into a binary file.The length of the string is 22 position 1036
Write name in that chain, the length of the name varies but is always between a length of 22.
As I can fill the remaining length of the string with blank spaces?
The empty spaces in hex is "00"

View 1 RepliesWrite binary file in sequence with Listview.I'm loading data from a *. bin file in a listview to modify.Now I want to write listview data in the file.The start offset is 1036.The sequence of each data block is 228 bytes.The number of times to repeat the sequence is 8011.There is more information ... but I put these 3 sample.In the first data block to these lengths are Name Offset 1036 +50 (name space long is 22 bytes)Age Offset 1036 +60
Nationality Offset 1036 + 62
I suppose that before writing the data in the file would have to convert the data item and subitems in hex or byte.
I'm amazed at this situation. In QBasic, you could just easily GET and PUT whatever you wanted at the exact position in the file that you wanted. Now in Visual Basic 2008 I'm just completely stumped.
I can't use FilePut or FilePutObject because of a twisted issue. It adds a couple of bytes to describe the length of the data being written: what's the point of BINARY read/write if it won't allow you to write EXACTLY what you want and nothing less or more? There's a way to turn off this issue, and that's by setting the parameter StringisFixedLength to TRUE, but that's where the twisted part comes in. You can't do that. As far as I can tell you have to redefine the function using SUB, for example:
[Code]...
My.Computer.FileSystem.WriteAllBytes. To my amazed surprise, this function doesn't even bother to include the possibility that I might want to put the data in a specific position within the file! I can't believe this. You can either specify to APPEND at the end or not, in the latter case apparently resulting in a write to the beginning of the file. No option at all to specify where in the file you want to put the data. I can't believe this.
How do you write to a SPECIFIC position in a binary file in VB 2008, and do it without the program deciding to add a few "informative" bytes to your data before it's written (totally undermining the whole point of binary files)?
I am using BinaryWriter class to write a binary file to disk. When I invoke the Write method, passing an unsigned short value, it writes it in little-endian format. For example:
bw.Write(0xA000);
writes the value in the binary file as 0x00 0xA0. Is there a way to make BInaryWriter use Big Endian? If not, is it possible to create a new class, inheriting BinaryWriter and overload the Write function to make it write big endian?

View 6 RepliesI am trying to write a simple application that monitors the COM port and writes the incoming binary data to a file. So, I gathered a File class is provided, but looking at its methods list in the Help page, I see no method for writing individual bytes (and the Write methods seem to close the file after writing).
How can I write a byte array into a file, keep it open and repeat this as necessary?

I need to send a broadcast over the LAN and then parse the results. However, the sending of the broadcast seems to be code that is direct to the LAN connection, as in it doesn't seem to write to a standard IP/port combo.

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!

I have a web service that is currently calling the DOS command copy to put a text file to a specified network share.
This is the code:
Imports System.Web.Services
Imports System.Web.Services.Protocols
Imports System.ComponentModel
Imports System.Data
Imports System.IO
Imports System.Xml

It appears doing this might be causing some problems and our front-end programmer suggested I see if I can output the stream "output" directly to the network shared printer specified by the SOAP request. Is this possible? This is VS 2010
I have seen writing to binary, but the question is how do I change from where it starts at in the file, supposively I want to start at byte 3 instead of the end or begining. Also is it 0 based? where zero is the first position, and how do I over write the data at the part I am at in position 3?[code]....

i want to read/write to some files.Specifically my application searches text files but i also want it to search binary files. The problem is : how will i know when the file is binary and not text ? Also how will i get the hexademical contents of a binary file ?[URL]
View 2 RepliesWhat do you think what is faster:
1. writing 1000 records in a binary file on a server? or
2. passing the same 1000 records in a database on a server?
and
1. search a specific record in a binary file? or
2. search the same specific record in a database file?
