My app displays the bytes downloaded in a label using: Private Sub MyDownloader_DownloadedByteCountChanged(ByVal ByteCount As Integer) Handles MyDownloader.DownloadedByteCountChanged lblDownloaded.Text = ByteCount.ToString() End Sub But I thought it would be 'nicer' if it display the amount as kb/mb/gb, etc.
I have a single that might have a decimal place but might not. I have to put the digit before the decimal into the first 4 bytes and the digit after in the next 4 bytes.
So 1.1 would be 01-00-00-00-01-00-00-00 or 2.1 would be 02-00-00-00-01-00-00-00 or 1 would be 01-00-00-00-00-00-00-00
The digit before the decimal point is stored like an integer in bytes the same with the digit after the point. So 1.1 gets split into 1 and 1 and then stored as 2 DWORDS: 01000000 and 01000000
I'm trying to send a 28 character string to a remote ip address and port. I've done this successfully in vb.net using the following code snippets:
Dim swon As String = "A55A6B0550000000FFFBDE0030C8" Dim sendBytes As [Byte]() sendBytes = Encoding.ASCII.GetBytes(swon) netStream.Write(sendBytes, 0, sendBytes.Length)
I now have to convert this across to c++ and have the following so far:
but am getting stuck at this point. I'm sure I'm missing a simple syntax error but I can't figure it out!To clarify, I'm not getting an error, but I don't think the string is being converted to bytes correctly as when I convert back, I just get a '01'
I am receiving a data stream which contains 4 bytes of data which need to be converted to a 32-bit float (IEEE 754). This was easy to do in C as I created a union with a 4-byte array and a 32-bit float. Job done. However I have no idea how to accomplish this in VB (pls note I do not code in VB).
Im making a database converter (phpbb to ipb)I noticed during analysing both databases that the posts of phpbb are converted to bytes as you can c here
I want to convert those to regular text again but I have no clue how to script my converter to lookup the bytes place (after 0x) converts the string (as the bytes arent in array) and where to stop converting the bytes (after the ,)then replace the bytes text by the regular text and this needs to be in a loop because all posts need to be converted to normal text.
I have to store the bytes of a image file inside of an XML file that is read by another program... The problem is, if I inject it as just plain bytes, the end-program has an error (presumably because it contains non-legal XML characters). How can I convert bytes into something that XML can legally read? I really have no other options at this point. I have to inject the image file as bytes (specifically a .bmp file).
i'm trying to convert an image into bytes in vb.net but i failed, i searched the web and threads over here, but seems that i couldn't find any working example or code.
Is there anyway to convert an image file bytes array into an array of the real RGB values of that image?
I don't really want to use GDI+ or the System.Drawing library, but simply apply a certain calculation/processing to every byte of the image file and get another array that contains the RGB values of every pixel in that image. I know it could be done as I know how to do it in a different programming language (Python) but not in Visual Basic.
I would like to know if there is any other way than using WriteableBitmap to convert the current screen into array of bytes.Because I am trying to get a screenshot of Esri map, but I am getting "pixel access not allowed" error
The application is working good, i can receive data on port 48888 and i can write it to my logfile, but my problem is when i convert bytes to string. I have the correct data, but all the bufferReadSize is filled with space. Example: if i send only: test, my log file will have test and 4 lines of space only. In my code, right after Dim clientdata As String = Encoding.ASCII.GetString(bytes).
I tried to trim(), replaceI() or any string manipulation, and it's not working!%!? Is there anything i need to do before i can start manipulating that string?
my project was intially mandated to be done in c#.however a large contributor to the project wrote much of the business logic, which he knows well, in vb.net.How difficult would it be to convert the following c# code into vb.net.
I'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:
Regular Expression: How to replace a string that does NOT start with something?
How will I select a substring with 2 criteria? I have a Richtextbox where I select a number after a : with this code; For Each line As String In Richtextbox1.Lines Dim equalsPos As Integer = line.IndexOf(":") + 1 txtFound.AppendText(line.Substring(equalsPos, line.Length - equalsPos)) Next This is working ok, but the whole line.length is appended for number2. The line ex. Some text:my number some text-my number2. I want my number appended to txtFound, and my number2 appended to txtFound2. With my code only number2 can be appended correct.
I want it to do is that you input a string, then you select an algorithm (Theres only going to be one RijnDael) then you input a key, then the Initialization Vector comes from "txtIV.text" then you select the key bytes and the block bytes from the numeric up/down, then you either encrypt or decrypt.
Ok i am having some issues designing a base-class to handle generics.Caveat is i need to restrict the type put in as a Numeric type, specifically Int16, Int32, or Int64 (Short or Long).I know you can do Of T as {Structure} but i dont want to select the key bytes and the block bytes from the numeric up/down.
I keep getting a ProtocolViolationException "Bytes to be written to the stream exceed the Content-Length bytes size specified." on the following code.I've tried setting Content-Length numerous ways with no success.
Dim url = "https://domain.com" Dim req As WebRequest = WebRequest.Create(url) req.Method = "POST" req.ContentType = "application/xml"
Does it read the entire message string sent by the client? I have a line to write to the stream later in the code and that does not seem to be sending anything back to the client, although the code around is excuting.
i = stream.Read(bytes, 0, bytes.Length) While (i <> 0) Try ' Translate data bytes to a ASCII string.
Probably missing something silly here, Her eis what my display looks like Sending image...(401303) I would prefer it displays as Sending image...(391 kb)
i wanna try to convert this ASM code into vb.net or at least find a solution that will allow me to enable this script after creating a handle on a kernel32 process.
I am looking for some library or code that will allow me to convert mp4 video to mp3I want it to be for free and compatible with the latest .NET framework (4).Also, if possible, I am looking for a free ffmpeg wrapper than I can have in my vb.net application without trial or messageboxes.
Will Microsoft Visual Studio 2008 convert my app to an app I can use on the Internet. I've used it to help convert up from 2005 but I'm looking so save time in creating a web app version.
