File I/O And Registry :: AVI Header - Program To Download And Play AVI Files The Files Are Large In Size And Long Time Wise

Dec 11, 2011

I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.

File I/O And Registry :: Check If Folder Is Writable?

Oct 25, 2008

I want to save a bitmap object to file, but I want to make sure the file path is writeable first. The user should have write permissions to the folder and it should not be a location on a CD drive.Right now, it gives a "A generic error occurred in GDI+", which is not too helpful. I'd rather tell the user that the selected save location is not writeable.

File I/O And Registry :: Create An Invisible Folder?

I am making a file program that will store information that a user can not edit without using my file system. The only two ways I can see how to do this is to either create an invisible folder to hold the files, or make my own extension. I think it would be easier to create an invisible folder through VB if possible. Can anyone point me in the right direction.

Retrieve File Details From Files In The Program Files Folder?

Dec 26, 2009

I am trying to retrieve file details from files in the Program Files folder. I receive an error while trying to retrieve file details.

Dim sFileName As String = ("%ProgramFiles%Windows DefenderMSASCui.exe")
Dim Info As FileVersionInfo
Info = FileVersionInfo.GetVersionInfo(sFileName)
Msgbox(Info.ProductName.ToString())

I receive file not found error at 3rd line. But if I change the path from "%ProgramFiles%Windows DefenderMSASCui.exe" to "c:Program FilesWindows DefenderMSASCui.exe" it works fine.

What should I do if I want to retrieve file details from the path which includes a "%" character?

File I/O And Registry :: File Stream - Backup Program That Zips Files ?

Feb 9, 2009

I 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!

File I/O And Registry :: When To Close Files

Jul 24, 2010

I should mention that I'm mainly concerned with Random files.Which is the best method?

1.) Open file, manipulate data and immediatly close the file. (Which means doing this alot everytime data needs to be read, edited, deleted, or saved)

(2.) Open the file when the app starts and let it open for data manipulation until it's time to close the app at which time the file would be closed.

I was always taught option 1. The main reason at the time was to cut down on the chance for data corruption in the file or an outright loss of the file due to outside circumstances like power failure.

VS 2008 Obtain CRC32 Checksum Of Files Within A Folder Then Rename Files And Folder

Mar 4, 2010

in the current project im making i've decided to add in some tools, 1 of which is a renamer based of a renamer app that already exists (called scdtoolz), i want to build my own version of it so i can learn some new things, and build a nice GUI version of it.[code]So what i have managed to determine is that the current app scans the folders contents for the CRC32 Checksum, and renames based of that, since the 456.bin's CRC32 Checksum was 2274F80B, and in the text file 2274F80B is found here 'WWF - Rage in the Cage (T-81015)(U)#2274F80B#'So now i have determined game identification is based of the CRC32 checksums, how would i go about coding a similar ap in vb.net?first i need to make the app scan a folder, but how to return crcchecksum? and then rename if check = XXXX? If MD4 sums are easier/simpler i can use those instead, im lookin at a few hash app sources now, so i think i can see how to get the md5 but not the crc32 yet, or how to rename the 2 files and folder based of the text file.

File I/O And Registry :: .Net 2003 Win App Can't See Local Files

Jan 25, 2012

I'm programming a small windows app that allows the user to fill out some fields and then creates and runs a batch file based on their entries. The program works, but it doesn't.The program creates the batch file just fine but when it tries to run the batch file, it gets errors in the cmd window saying it cannot find the scripts the batch file is trying to call. What's confusing me is that if I take the batch file the program created and run it myself, it works just fine so I know it is not the batch that is the problem. My best guess is that there is some security setting for vs.net that I've overlooked but I am only an "every once in a while" programmer so I really don't know where to look. Additionally after running the batch, the program is supposed to delete the batch file but that fails as well with the message that it cannot find the batch file, the same batch file that it had just created and run.

File I/O And Registry :: Random Access Files In .NET?

Nov 2, 2009

how to read and write random access records in .NET. Now I know random access files are dead and the response on every query I found with google/bing/yahoo searches was don't use random access use Binary serialization but I can not. I have a situation where I need to read and modify 256 byte records in a file that is used by another application.

Now for a bit of background the file is made up of 27 fixed length records of 256 bytes. Each of the records has a separate structure consisting of 30-120 fields. The proplem I am having is I can create the record structures but when using the FileGet method I am receiving an error. Now I have found samples that showed the same format I am using that claim to work.

The error I am getting is Option Strict On disallows narrowing from type 'System.ValueType' to type 'ProgramName.ModuleName.Record' in copying the value of 'ByRef' paramater 'Value' back to the matching argument.

The basic layout (simplified) is as follows:

Code:
Structure Record
<VBFixedString(6)> Public SomeParam as String
Public SomeNumber as Short

[Code]....

Now the overloads for FileGet show all of the data types including Object. But I have tried various methods to retreive the 256 byte record but without success. Do I have to actually read each of the several hundred fields of the structure one by one? Or am i overlooking something (I have been known for this in the past)

Or (and I'll kick myself if this is the only way) do I just have to set option strict Off in the module and the code as above will actually work.

I would love to be able to just ditch the random access file but I have to keep it for compatibility with several other applications at this time.

File I/O And Registry :: Using .NET 3.5 To Retrieve Files From IBM Mainframe

Jun 2, 2010

I know how to get a list of files in a local Windows machine's specific directory:

Dim dirInfo As DirectoryInfo = New DirectoryInfo("C:Temp")
Dim fileListing() As FileInfo = dirInfo.GetFiles()

But how do I use this class for a mainframe system where user ID, password and 'change directory' command are needed?

When I attempt to just access the server without credentials and just do the Windows version and use the syntax "\server_nameAUTO:RPTS.", where 'AUTO:RPTS.' is the mainframe directory name I get the following error: "The given path's format is not supported."

When I just use '\server_name' I get: "The UNC path should be of the form \servershare."

File I/O And Registry :: Zip Large Number Of Files?

Aug 28, 2009

I am using zipforge.net to archive files in a small backup program I am creating. Everything works fine however if I try to archive a large number of files the process of zipping them gets slower the further along in the job it gets.

Example: I have a directory that contains a little over 100,000 files in it. Each file is only about 200k of text. When I use the zipforge zip class it starts zip'ing very quickly but as it gets about 40% of the way through the directory it starts to slow down... at about 60% its working at a snails pace.

Memory usage for my solution also goes up proportionate to the archive file size as it grows. Currently it takes around 26hours to backup this directory which only contains 4 gigs worth of information.

If I use a program like winzip I can zip the folder in less than an hour. I am thinking there has to be a way to write to the end of the zip file without having to open it every time or without keeping it open. My backup software scans the specified folder and writes each file path and name into a text file. Then it reads the text file line by line and passes the path + file info to the zipforge addfile().

File I/O And Registry :: Accessing Files In Alphabetical Order?

Nov 20, 2009

For a project, I need to extract all the frames of an AVI video. This I have accomplished by with free program. The problem: it took a 30 second clip and spit back 5400 some frames, and the image only changes every 20 frames or so. I really only need about 270 frames, but I didn't want to go through each one manually. So, I wrote a small program using Visual Studio 2008 and VB to open each image in binary and compare it to the one before that. If there is a discrepancy of more than 55000 (to accommodate slight errors in capturing), it leaves the file be. If not, it deletes it.

After much troubleshooting, I got it all to work. I ran it on the directory containing the images, but when it finished, only the first image remained. I checked into it, and found that the FSO loop I have set up to loop through each file was pulling the files in apparently random order. It will give me the image "bg(01).bmp" and then immediately "bg(1362).bmp" and so on. And the order changes every run.

I tried setting up an array to generate a list of all the files and then sort them, so I could pull off the name of the file, then the next one, ect. but it took over 3 hours to finish processing the array, and then It was using a huge chunk of RAM.Is there some way to "force" vb to pull off files in alphabetical order? here is my, code, it belongs with a form. fPath is a global variable, simply pointing to the source directory.

File I/O And Registry :: Copying Multiple Files From An Array?

I'm trying to copy multiple files from a directory, put them into an array, then copy just the 30 newest files(I haven't coded the 30 newest loop yet). I added a list box to the following code just to ensure the all the files are storing into the array properly... they are. When it try's to copy, it renames the first file to .log, then tells me that the .log file already exist. How do I get it to copy and keep the source file name in the destination folder Eventually I'll loop this and grab only 30 of the files.

Here's the code I'm playing with:
Private Sub transferButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles transferButton.Click
