I have developed a system to update various programs. I put the programs updated into a particular folder of my site and Users can launch their update program to download and update their application.
The user interface has two progress bar, one for the single program in download and the second for the total download.
For calculating the total amount of bytes for the second progress bar I need to know the dimension in bytes of programs and files to be downloaded before start downloading. See the attached code.
For that I read, in remote mode, the size of all the files checked and I obtain the total amount of bytes.
All works fine with various type of files (.EXE - .DOC - .JPG - .TXT etc).
The problem arises with the Crystal Report file (.RPT).
The error 404 occurs but the file exists, the server WEB is active and the other files of the list are summed. If I compress the same file in .ZIP all works.[code]...
I was wondering if it would be possible to check the file size of a .exe on a website and see if it's greater than or less than the program running it?

Alright here's my situation: I have a form. This is a very small form that can be moved with the mouse (formborderstyle=none). The transparencyKey is 0,0,1. The form back color is 0,0,1. There is a label on the form. I drag files to this label(its backcolor is black[0,0,0]). What I want is for the filesize to be checked. I already have the uploading to ftpcode, I just want to know if the file is above my limit I set. (250mb per file)

I like to compress the xmldata before the data is provided to the client as an excel file. I am trying to compress and deliver it as a .zip file. its not working Here's my code below. I tried compressing it, converting it to bytes etc etc. The issue with below code is, the XSL transformation is not happening properly and the output excel file is raw xml with some .net exception at the end. (that's what I see on the .xls file that's downloaded at the end) Before I started working on compression my below code was working fine that gives properly formatted excel file from the xml input. the excel file is so nice you can't even tell it was from XML.

Language: vb.net
File size: 1GB, and stuff.
Encoding of the text file: UTF8 (so each character is represented by different numbers of bytes).
Collation: UnicodeCI (when several characters are essentially the same, the most popular version will be the one unique.). I think I know how to handle t his one.
Because each character is represented by different numbers of bytes and each line has different numbers of characters, the number of bytes in each line also vary.
I suppose we have to compute hash for each line. We also need to store buffers location where the line each. Then we have to compare buffers. Then we will check whether the same line shows up or not.
I was using the following code to check the file size of a data file on my local machine. Now the data files have been moved to a mapped network drive and this code no longer works. What do I need to change or how do I access file size on a mapped drive?

I'm working on a school project right now and I have everything fine except this one part of the project: "The audit and errorevent logs should be archived if they are larger than 5K and up you need to keep up to 3 copies of the files." I know how to read and write text files just fine, so I don't need help with that. What I don't know is how to archive a file based on file size, or how to keep up to 3 copies of the files?

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
how I could check if a certain file is in text or binary format?I'm using VB.Net 2008 Express.
View 2 RepliesI want to create an application where a user can create a file which is a certain file size. e.g. Two textboxes, one for Name of file and one for file size. When submit button is pressed, a file is generated from the textbox information. Here is what I have got so far:
Imports System.IO
Module Module1
Sub Main()
[Code].....
However this code is only for text files. I want users to be able to specify a file extension. The file doesn't need to work, it just needs to have a certain file size and a certain name. e.g. I can use this application to create the file Song1.mp3 which is 4567kb. It won't play because it is not a valid mp3 file which is fine, it doesn't have to.

I need to read and process a text file. My processing would be easier if I could use the File.ReadAllLines method but I'm not sure what is the maximum size of the file that could be read with this method without reading by chunks. I understand that the file size depends on the computer memory. But are still there any recommendations for an average machine?

I have a routine that uses windows compression to zip a file. It uses shell32. Rather than maintaining a five second timer for each file, I would like to check to see if the file is closed, not locked, etc., before moving on to the next step in my program.

I (SQL Server DBA) have inherited a VB App, being called in a TSQL Script, that creates a PDF using the Crystal reports. Until a month , PDF was being generated with correct extension and size, but for some unknown reason the app creates a non PDF file with Zero size. Interestingly the script that calls the App and send the PDF created as an attachment in an email via MS Outlook, sends it as PDF with data.
Also when trying to open up the same 0KB file in Acrobat, gives an error:
"Could not open because it is either not a supported file type or the file has been damaged (for example it was sent as an email attachment and wasn't correctly decoded)"
FYI, the Exchange server was upgraded so the email isn't working either and its causing a great pain for management to not to be able to have that report.
Is there a correct way to getting the file size when uploading an image with ASPxUploadControl? When the file is uploaded I would like to show the file size. So far I've not found out any sample code on how to do it via Google.
