As discribed on this MSDN pageWhat would be the PHP equivalent? Is it even possible to do the three things listed on that page under remarks Streams involve three fundamental operations:You can read from streams. Reading is the transfer of data from astream into a data structure, such as an array of bytes.You can write to streams. Writing is the transfer of data from a datastructure into a stream.Streams can support seeking. Seeking is the querying and modifying ofthe current position within a stream. Seek capability depends on thekind of backing store a stream has. For example, network streams haveno unified concept of a current position, and therefore typically donot support seeking.
I'm trying to convert something from C# to VB.NET and I'm having trouble finding an equivlent in VB.NET to C#'s yield keyword. I realize 'yield' is not a convertable keyword to VB.NET, so can someone please show me how I would implement this code in VB.NET. I got all of it converted over except for the implemented GetEnumerator() function. It is simply a class that implements CollectionBase and IEnumerable (to make it LINQ worthy):
[Serializable()] public partial class Customers : CollectionBase, System.Collections.Generic.IEnumerable<BusinessLayer.Customer> {
what is the Equivalent of a Static class in VB.Net. Is it Modules?And When i used one of the C# to VB.Net conversion tools then the code "Public Static class Class1 " was converted to "Public NotInheritable Class Class1"
I have a problem with the filereader class (i think). My program has server/client interaction and the client reads from a text file, sends the data to the server. The problem is, the client is sending the last line of the text file twice, so for example I use test data in the text file such as:
Test data 1 Test data 2 Test data 3
The server will receive: Test data 1 Test data 2 Test data 3 Test data 3
Here is my code, I have a feeling it is to do with the filereader.endofstream loop. Private Sub readLine() Dim filePath As String = ("D:outputLog.txt") Dim fileReader As New StreamReader(filePath) Do chrMessageToSend = fileReader.ReadLine() [Code] .....
i am creating a program which scans and saves images. in my program i have the option to save images and with each image i save it gets its own number for example: file1, file2, file3, file4 and so on. the only problem i have is getting the prgram to remember where it left off so it carry's on the number. my understanding is that i need to create some sort of stream writer or file stream class for this proccess to work. so it save's the last image number i was on, and carrys it on next time i open the program up again. and i also need it to re-write the new image number its on for next time. so i need to write and read the text file (.txt) and write it again if you catch my drift? i have a book to help but the wording in it is so confusing at the min, i m lost where to start.
I am working on an Examination system for a secondary school. The system captures the marks of students of the subjects they take and stores them in the database. from there, it has to compute the grades of marks for each subject that a student takes and get the position of that student in the stream and in the class.
For the gradeing part of it, I have already made it, my problem is to get the positions of students and show them on the rdlc report.
The word class and stream here, I mean;
The school has six classes, senior one/form one TO senior 6/form 6 as classes and each class(form) for example senior one has 4 streams. By streams, I mean; Students are grouped into different streams but under one class(level/form).
for example; form1 A TO Form 1 D that is one class/form secondary level. form 2 also has four streams ( form 2A, 2B, 2C, 2D) and so on. So a student can be number one in his stream but if the marks are compared to other streams of thesame level, he is number 3. it is indicated on the report as Position in Stream 1...........Class 3
I'm trying to set up a CLASS to represent a data stream.This is a newbie question so if the answer is obvious, please excuse me.Several of the data items are multiples which I would normally represent as an Array element.For example, in the code below, the element SolarNameplate has up to 10 instances, so I'd like to use array notation.I get errors, and it doesn't work, so I assume I can't do it like below.
QUESTIONS : 1 - is it possible to use an array element in a class ?
2 - is there another way to achieve what I want ?
Public Class SM1PS01 Private _Projid As String '... name or number of project Private _LogoFile As String '... file containing customer logo[code]...........
If I have a module in a VB.Net class library, will it's visibility be limited to the assembly? What I'm looking for is the VB.Net equivalent of a C# internal static class.
I'm trying to send a XML serialized class over a network stream
the send is working
Dim IP As Net.IPAddress = System.Net.IPAddress.Parse(IPAddress) Dim IPE As New Net.IPEndPoint(IP, 10003) Dim TCPClient As New Net.Sockets.TcpClient
[Code]....
I always get an error {"Unable to read data from the transport connection: An existing connection was forcibly closed by the remote host."} The XMLFile has the xml document in it most of the time and I can go on and everything works but 1 out of every 5 times it doesn't work at all and the XMLFile contains nothing ..
in an winForm app in VS2010 win 7 compiling to x86, I try to do what Alvas.Audio seems to work. See (c# ex: [URL] for reference.
Dim data() As Byte = wr.ReadData(second * i, second)
The result give me data.length()=0. I do not have any exception, I can read format from it and whatever reader I use I got this problem.EDIT : After some tests, it seems like the uncompressed file I create in the first step (in PCM format, with .wav extension) can not be recognized by the Alvas.audio library for the second step. I must miss something around Audio file markups or something alike.
Here is the code that might be the source (basically this is step 1):
Dim functOut As String = String.Empty Dim wr As Alvas.Audio.IAudioReader = Nothing Dim fs As IO.FileStream = Nothing

How can I write the resulted stream to be sure I can read it again later?
Im making a desktop player for a online web radio, and for the program I wanna make it show all the stream info. Like the stream name, and such. However I dont know how to do this? I looked everywhere
The server url is setup like this "[URL]" And it has all the stream info and that there. So is there a way I can get the info from there onto like say a label? Live updates btw.
I have a problem with the cryptostream, if i write the stream to a memorystream the memory that the stream used is still alocated and i have no way of unalocating it.what am i missingdoing wrong? im using-using on the streams,readers and crypto stuffs so the framework should shut them all down right? i tryed calling .close and .dispose but nothing ,in fact i moved it all over I have provided the sub that im using for the encrytion im in .net 4.5 so there is a lil async stuff but i know thats not the problem coz i moved this code out of my main app(.net 4) for testing to see if i could fix the problem.[code...]
If Class X is within the scope of Class Y, is X a subclass of Y?If Class A is a sub Class of B, then is Class B considered a super class of A?if Class C inherits Class D is Class D a superclass or parent of Class C?if Class E extends Class F then we can consider Class E a child of F?if Class G inherits Class H and is within the scope of Class I then who is the parent of Class G? Classes that inherits Class J and classes that are within Class J are all sub classes of Class J?
I have put this code in the global form Inherits System.Windows.Forms.Form. And then in the form that will inherit this from the global Inherits MenuStrip. "MenuStrip" is what the global form is called. But keep getting this error: Error1Base class 'MenuStrip' specified for class 'Lesson2' cannot be different from the base class 'System.Windows.Forms.Form' of one of its other partial types.
It is in the file ClientProfile I have placed in both App_Code and also App_Code/Models
In my code behind I have the following
[CODE]...
The last word, "ClientProfile" has the scary squiggly red line below it. It is not recognizing my class.Even the Intellisense is not picking up te class. Do I have to register the class file in any way?
Dim a as Type=GetType(className) would gimme the type. But I have only the name of the class as string. I want something like GetType("class1") which would return the type.
I know that AndAlso is equivalent to && and OrElse is equivalent to ||. But what is the cleanest way to achieve the equivalent of Visual Basic's And and Or in C#?For example, consider the following VB.NET code.The ValidateForControl method performs some validation and returns whether the state of the specified control is valid. The entire input form is valid if all controls are valid. However, each control must be individually validated even if one is invalid (which requires the operator not to short-circuit). Visual Basic's And operator is perfect for this situation, but unfortunately there's no equivalent operator in C# as far as I know (&& short-circuits).
What I am trying to do is to check if a value matches one of two numbers (and easily be able to add to the numbers to compare to). Rather than doing a longer-winded way such as: [Code] I have found that this only works when SectionID is 2 or PageID is 8. If SectionID is 3 or PageID is 12 then it doesn't work. Why is this and what can I do to try to get around the problem?
I'm loading blobs out of a database as a byte array and I put them in a memory stream so that I can load them into an xmldocument for parsing.However there are blobs that have multiple root nodes, this causes the parser to blow up.My solution is to just make a new root node that encompasses the whole blob. I can add onto the end just fine with a streamwriter however I can't figure out how to add onto the beginning.How can I prepend to a stream?
Update:I was having too much trouble getting this to work. The "XML" I was extracting was not proper XML and I kept on having to add more and more regexes to remove bad XML before the XmlDocument Load. I ended up using the HtmlAgilityPack to parse out my valid sections of XML and I put those inside their own xml documents.
I'm writing a VB.net application (but you can answer in C# if you want, no problem) that uses a 3rd party .NET library. In particular, one method in this library takes an IO.Stream as input (among other things) and writes the results of its processing to said stream. My problem is that the method CLOSES the stream after writing to it, so I can't read back the data that it wrote in it!To be more specific: it works, of course, if the stream is a FIeStream , since it writes the data on disk, but what if I want to read the data directly to memory? I tried using a MemoryStream, but as I said, when the method returns the stream is already closed, and I can't read back anything from it.
