I am developing a VB.NET 2008 application, consisting of a main EXE application and several resource DLLs.I am trouble with two functions for the DLL:
1) one function to get a list of all files in the resources of the DLL.
2) one function to return 'by name' a resource file as a System.IO.Stream type.
NOTE: The files will not be "Embedded Resource" (this doubles the size of the DLL), so I think cannot use 'GetManifestResourceStream'.
I currently use:
Return New System.IO.MemoryStream(My.Resources.MyFileName)
but I want it to be called by name.I am adding the resources using the VS 2008 "Resources" tab, from the My Project screen, I'm not manually editing Resources.resxAs I said before, it works with:
Return New System.IO.MemoryStream(My.Resources.MyFileName)
but I need to get the resources by name, which also works by using
GetMAnifestResourceStream
but this requires to set the resources Build Action to "Embedded Resource", which doubles the size of my DLL file.I currently use "None" as Build Action, but I can use any Build Action that does not increase the file size more than the actual resources size.
I have a module which will be responsible for parsing CSV data received from different user via a website interface, and I have to parse that CSV. I was considering to use, TextFieldParser for it.
But before I could implement I was considering what shall be a better approach...
Generating MemoryStream from data received,
or initialising a StringReader from the same input string.
When I use Dotfuscator Enhanced Community Edition to dotfuscate one of my programs, it breaks the part of my program that takes an ebmbedded GZIP file and decompresses it to a normal stream which is then written to a file. Here is the code that dies:
VB
Dim Stream As New GZipStream(Reflection.Assembly.GetExecutingAssembly().GetManifestResourceStream(MyNameSpace & "." & EmbeddedResource), CompressionMode.Decompress)
I did some investigating by putting in messagebox outputs of the variables and it seems the reason it dies is because MyNameSpace is a blank string. This global variable is defined early on in the program as such:
VB
Public MyNameSpace As String = System.Reflection.Assembly.GetEntryAssembly().EntryPoint.DeclaringType.Namespace()
So what I need is either another way of accessing the root namespace, another way of getting to an ebmbedded resource or a way to make Dotfuscator not destroy that namespace. I did think about using My.Resources.... but the problem with that is that I can't pass the string "EmbeddedResource" to the subroutine - I'd have to do the files all in individual lines I think.Also, a side question: The only enhancement I can ever find with the Enhanced edition of Dotfuscator is "Deep Visual Studio Integration" but I cannot see any evidence of this. I mean there's a button in the Tools menu to start Dotfuscator but that's not what I'd call "deep integration". I assumed it meant you could tell it to automatically dotfuscate when compiling but I can't find any documentation on how to do this.
So i created resource file New --> new file --> Native Resource Template Then added icons with custom id, like "x", "u_100", .. so i understand, what the files (in my case icons) is.. And i saved as 32-bit resource file (*.res) So i have a question, how can i use these files inside of resource file in my apps? i know how to add icons in to my app.. Me.Icon = New Icon(C:/icon.ico)
View 6 RepliesI have a resource file that I include in my shared code library that has all of my re-usable classes in it (all the resources go into their own namespace). Now, what is the best practice regarding resources... should I include them in the same DLL, or should I have a seperate resource DLL and/or are there any benefits from seperating them out into their own file.
View 8 Repliesin 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?
I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
View 1 RepliesI am writing a backup program that zips files. Using some sample code I have the following that creates a zip file. Problem is it does not get any subdirectories or files. Where am i going wrong?
Dim azFileNames() As String = Directory.GetFiles(SourceFolder)
Dim objCrc32 As New Crc32()
Dim zipStream As ZipOutputStream
[CODE]...
Alternativley, there is another component to the zipping dll that I could probably bypass the above altogether. It is: FZ.CreateZip(DestFile, SourceFolder, True, "", "") Where DestFile is (Output stream as system.io.stream). I'm trying to read all the files, directories, sub dir and files, etc from a specific location, let's say 'My Documents' into Destfile in which the FZ.CreateZip zips the file. FZ is FastZip which is from icsharpcode.net. They have c# examples, but that's greek to me. I'm trying to just learn VB!
If i use a stream to modify few bytes in a file without changing the total number of bytes
does the stream rewrite all the file even if just few bytes have been replaced?
Is there anyway to take a static stream reader, and switch it to another text file based on the user changing the file?

View 2 RepliesIm 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 am making a game in which the file stream gets a certain file(lets say a.txt) and it reads it, if it has certain values stored in the file it returns boolean(this is a function), then a sub procedure writes to the file using a streamwriter and a filestream using the same file. I am having problems, sometimes visual basic says that another process is using the file, this is before i closed the filestreams and the streamwriter or streamreader, then it gives me errors when i close the files, it tells me that it can't access a file that is already closed, i thought the filestream gets the file and lets the streamreader or streamwriter read or write to the filefound out the problem?

I'm trying to use a .pdf file I've added to my project but can't figure out how to get it to show using the webbrowser control. Here is what I'm using to call it:
View 9 RepliesI've downloaded ZLIB.NET from here and the example VB.NET code they provide works fine. It's very short so I'll paste it here for reference:
vb
Public Shared Sub CopyStream(ByRef input As System.IO.Stream, ByRef output As System.IO.Stream)
Dim num1 As Integer
[Code]...
Note that the CopyStream() subroutine is identical. The problem is that although decompressing seems to work fine, compressing does not. If I take a byte stream, compress it and then decompress it using the above code, I get a truncated version of the original stream (as an example, a 360485 byte stream becomes 311518 bytes). The resulting bytes match the original stream up until the point where it's cut off.
The only information I can find about streams being truncated is due to missing stream.Flush() commands but the output stream is flushed in the CopyStream() subroutine.
I am trying to read a xml file (from a stream) like the one below. I need to read the xml element "recipientPhone" first,then I could read element "contents" so that I could save base64 data as file with the name coming from recipientPhone.I am using while xmlReader.read() to read the xml, is there a way that I could read element "recipientPhone" before "contents"?
xml sample:

I need to refer to some strings using an "indirect string" in the registry. It should be in this form:

View 10 RepliesI am trying to write a little synthesizer program, and as a first step I am creating .wav files opened for reading and writing using the code below called from a button click event handler. The audo plays but once, no matter how many instances of the Audio.Play method are called. I also tried closing the file and then calling the Audio.Play method on the full path name. In each case, the audio plays but once. If I click the button again, the file will be played once more. The duration for the audio is one second, so I am sure that it is only being played once every time. I do not want to loop the data. The idea is that when the user plays a new note, I update the file and replay it with the new data. Since the file is recreated every time I click the button, I guess what I *need* is working, but I am still curious why I cannot replay the content of the file.
