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.

Get Values From Registry Files?

Nov 18, 2009

Is there any way I can open a registry file that is not from the local machine? I have the software and system files from another PC and need to create a small code to read and get values from the files. The other PC is down and I just have the registry files so I ruled out the OpenRemoteSubKey method. However, the My.Computer.Registry.GetValue only works on the local machine.

Is there a way to get a list of files in a certain directory and then put them in a context menu strip then when they are clicked have the program open the file. I'm trying to make a flash player that can show the list of flash files and when you click the file path on the context menu strip it will play from that file. Here is what I have:

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.

Change Registry Settings To Open Eml File From Web Pages In Outlook Express?

Jul 10, 2008

I couldn't find an appropriate forum which would suit the type of problem I am facing so I am putting it here.I needed to create an intranet web application that has pages with hyperlinks to eml files. The eml files as is known are email files in MIME format which outlook express can open. However what I found was if eml files are on your machine, it opens in outlook express but when opened as an hyperlink, it opens in Internet Explorer (IE) as an mhtml file. And any attachments that may be in the eml file are not displayed at all!I didn't understand why IE has to poke inbetween. After searching the net, I came across a solution that required changes in the Registry of the client machine.The change is to be made to the node HKEY_CLASSES_ROOTMIMEDatabaseContent Typemessage/rfc822.The following is a REG file that can be imported for this change.[HKEY_CLASSES_ROOTMIMEDatabaseContent ypemessage/rfc822]"extension"=".eml""CLSID"=""However after this change, though eml files opened in Outlook express, MHT files stopped opening in IE.Then I simply deleted the rfc822 node and to my surprise, MHT files opened in IE and eml files opened in outlook express and everything was fine!!But I don't want to use this sledge hammer solution. I want to know what this registry key is for and how can I set it to achieve what I want . i.e. open eml files from web pages in outlook express without affecting other file types

VS 2005 Using The Process.Start Function To Open A Program Based Off A Registry Value

Aug 30, 2011

I am using the Process.Start function to open a program based off a registry value. It works, sort of. Here is the snip of the

Imports System.Data.SqlClient
Imports System.Console
Imports System.Configuration

[Code]....

The program opens with the correct registry value, but the program itself does not run quite right. This program feeds into Intergraph and brings up the selected drawing, but there is a feature of intergraph that doesn't work. If I manually start ( double click ) pdsicon.exe the program works just fine. It only when I call the process that it doesn't work quite right.

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 :: Reading Text From Non-.txt Files

Apr 24, 2009

An application that my company uses stores report files with a .dat extension for use with their software. These files can be opened in notepad and the basic report information can be seen as text. I am attempting to write an app that opens and reads data from these .dat files and displays it in a checked listbox. My hangup thus far is that I can't figure out how to read the data from the .dat files since they are not .txt files. Can anyone point me in the right direction?

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().

VS 2008 Registry - Opening Multiple Files?

Mar 27, 2009

I have made a registry entry as follows: HKEY_CLASSES_ROOTMy AppShellOpenCommandAnd gave it the value: "C:Program Filesmyapp.exe" "%1" "%2"I also had a drophandler to for the apphis entry works fine for opening one file that is dragged to my app's icon. The problem is that I can only drag one file at a time into the app. If I try to drag more, it only ees the first file and ignores the others. I use the My.Application.CommandLineArgs array to access the command arguments. For example, My.Application.CommandLineArgs.Item(1) will open the file. If I change the registry entry to:"C:Program Filesmyapp.exe" "%1" "%2" "%3"This will open the first two files, but ignore the rest. If I change the registry entry to "C:Program Filesmyapp.exe" "%1" "%2" "%3" "%4"This will have the same behavior as the previous entry and ignore all but the first two files.

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?

Mar 28, 2011

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

File I/O And Registry :: Reading Files From A Large Directory?

Jul 15, 2009

I wrote a cleanup program to go through some directories and delete files based on if the creation date is older than say 6 months. It works fine with some of the directories I have that contain around a few thousand small files. However, there is one directory (that contains small backup files from another program) that is loaded with over 300,000 files and it locks up on me as soon as I read in the first file in that directory.I am convinced it is the directory has too many files in it to open it. The server that the directory is on is slow. It takes a half hour to open the directory while on the server itself. I know it will take forever to delete the amount of files I want to delete, but I don't understand why it gets stuck and hangs there with no error message.Here is where I get stuck. Listbox1 is the directory I'm attempting to access

For Each selectFile In My.Computer.FileSystem.GetFiles(ListBox1.Items.Item(Count), FileIO.SearchOption.SearchTopLevelOnly, "*.*")

How To Open Multiple Files Using "open With" Command Line Arguments

May 15, 2012

I have an application that can read certain types of files, and I have it working so that if you do "open with" from windows, it automatically starts the application and opens the selected file.

Unfortnately, I cannot get it to work for more than one file.

System.Environment.GetCommandLineArgs() contrains the following:
System.Environment.GetCommandLineArgs(0) = name and path to the .exe
System.Environment.GetCommandLineArgs(1) = name and path to the first file selected to be opened

System.Environment.GetCommandLineArgs().Length is 2 when the user tries to open 1 file, which makes sense since the first argument is the .exe itself and the 2nd is the path to the file, but it does not increase to 3 if the user tries to open 2 files... meaning that System.Environment.GetCommandLineArgs(2) is never populated Here is some sample code that shows the problem: It will recognize no files or 1 file being opened, but if you try to open multiple it will only show the first.
