VS 2008 Getting File Size From An Array Into ListView?
Mar 13, 2010
I'm attempting to get the size of a bunch of files located in a directory with an array. Using a single file, it works great. But as an array, I get an error. This is the code I was using:
VB .NET
Dim filepath() As String = Directory.GetFiles("C:Test", "*", SearchOption.AllDirectories)
Dim lvi As New ListViewItem
Dim fi As New FileInfo(filepath.ToString)
[code]....
It works... kind of. It adds each file to the ListView, when I just want the whole sum. I was hoping I could just use "DirectoryInfo" from the System.IO namespace, but everything I've been reading says I need to loop through the files.
Ok I've tried for a while now but i cannot figure this out.I want to be able to take a text file of any size and convert it to a 2 dimensional array. Doing arrays with a set size is what i understand but i cannot figure out how to write a loop to find the size of the text file to be put into an array.
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)
Does VB2008 have the same limit on resource files as VB6? I was trying to store a large text file in my VB6 app (almost 3 mb) but all I could access was 32k of the file. I need to be able to compile the 3mb file into my .exe.
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?
When I store a binary file in a MS Sql table & then retrieve it & write it back to disk the new file is always 1 byte bigger than the original file, no matter what the file type. Is this normal? The files all open fine in their respective applications, but I'm just wondering where the extra byte comes from & if I'm doing something wrong in my code.
Using con As New Odbc.OdbcConnection(conString) Using cmd As New Odbc.OdbcCommand("insert into mytable values (?,?)", con) Using fs As New IO.FileStream(filename, IO.FileMode.OpenOrCreate,
Dim strUserDir As String = Environ("USERPROFILE") For Each foundFile As String In My.Computer.FileSystem.GetFiles( _ strUserDir + "\AppDataLocalMicrosoftWindowsTemporary Internet FilesContent.IE5", _
[Code]...
But How can i make it show the file size of that folder? or the "foundfile" string?
Im trying to resize a picturebox dynamically using .size.height and .size.width Its not working. This is the error message: "Expression is a value and therefore cannot be the target of an assignment." Never used height and width before. Been trying to find the answer, but it seems beyond me. Im sure its easy. Anyone know whats wrong with this?
How do you change the size of a listview when the number of rows grow when a different where select is commanded on textchange. I have a textchange on coustomer name which fills the listview with just the names that start with the letters as they are typed in, this bring up the listview with those customers. I would like to change the lenght of the listiew when the row count increases.
I have a question regarding multiple page printing. I know that it has to do with e.HasMorePages. I know that there has to be a condition that sets that flag to true and back to false or you get caught in a never ending print page loop. However, I have no idea where in my simple little print block here to implement that. As you can see I'm just printing a readline. Sometimes the file extends past a single page though depending on circumstances.
Dim strReader As StreamReader strReader = File.OpenText("auditlog.txt") Dim x As Integer = 10 Dim y As Integer = 10 Do While strReader.Peek <> -1 e.Graphics.DrawString(strReader.ReadLine, New Font("Times New Roman", _ 10, FontStyle.Regular), Brushes.Black, x, y) y += 12 Loop
I have wondered the solution to this question for many years! I doubt if anyone else knows much about it because the internet is absolutely zero help in this!
I have made a form1 with a webbrowser control on it. When the program is run it brings up the homepage (which is Google). However the homepage doesn't seem to fit inside the webbrowser control.
So I am hoping that someone could tell me how to make the (...I dunno how to ask this retarded question...) webpage fit completely (100%) inside the size of the webbrowser control. Meaning...I would like to see the entire webpage from the internet in the size of the webbrowser control. To fill the entire size (whatever size I want).
Etc... if my webbrowser ontrol is seh, set to 600px by 400px, how can I program this so when it brings up the homepage (or any other page), it fills the entire size of the webbrowser control? Without any scrollbars. How to make the contents from the web (or local) fill the size of the webbrowser - almost like a mini browser if you will.
I developed a form application on my computer, but when it was used in another computer with different screen size, i was told the form didn't fit. Do I have to adjust the form size or any other ways to let the form compatible on different screen size? (could be different screen size or wide screen)
I am using a textbox which handle the name of the employee and when it get focus i am using a listview with detail view which shows all available employees and user have to select any of them. I am using all this control in a panel, unfortunately listview need more size then panel, and i cannot increase the size of panel. But placing listview inside the panel make its child control and hide the half list view. Is there any way that i can show full list view control under the textbox?
I'd like to create a new file everyday for a logging application to minimize size when accessing. I'm after a couple of pointers with respect to when to create the file, and what checks to do etc.
I'd like to autosize listview columns to fit the column names. From what I saw this should do it but it doesn't work for me. Can someone see what I'm doing wrong or know of a way to do it? The listview is designed to dynamically build the coulmns based on the number of coumns in a recordset.
I have a list view populated by a database. The columns for each record are First, Last and EMPID. When I look at the list view on the form at runtime, I can see some/all of the First name and then below that may be part of the Last and some ... periods and no EMPID. When I hover over the record, I can see the EMPID. Is there a way to have all of the information in the record visible in the list view?
I have a ListView w/filename, data, time and size fields. I've copied the code from this article [URL] to use in my solution. Problem is, when I click a column header the first time, it sorts, but when I click the same header a second time, to sort in reverse, the column stays in the same order as it was just sorted in.
I found the following links to fill a listview and then write it to a CSV.[URL]..And I modified the codes and created the project which is attached to this post.
The project works OK but my only problem is that when it creates the CSV file, columns are not created in excel. For example if I expect the data to be placed in A1, B1 and C1 cells, the data will all be placed in A1.
increasing the size of my array. i have this code but i don't know which of these code does not increase the size of my array even though i increment it.
This is the declarations: Dim movieArray(0) As String Dim ratingArray(0) As String
What is the maximum size of a multidimensional array in VB.NET (in my case two-dimensional)? I'm using Visual Studio 2008, Framework 3.5 I found in msdn [URL]: "The length of every dimension of an array is limited to the maximum value of a Long data type, which is (2 ^ 64) - 1. The total size limit of an array varies, based on your operating system and how much memory is available. Using an array that exceeds the amount of RAM available on your system is slower because the data must be read from and written to disk." However, I am trying to use an array of data type single, with dimensions 64513 by 301 but Visual Studio seems to freeze when I execute the line to redimension the array ( Redim myArray(64513, 301) ). I have 4Gb of RAM and am using Windows XP (32-bit).
My app is receiving data in blocks but I don't know what size data will be received until it is finished, unlike file reading. So my app loads the data in chunks of 1024 bytes and then stops when there is no data to read. My question is, is it possible to keep increasing the size of a byte array as the data is being received?
I want to write an extension method that works with all kinds of arrays (Integer, String, Decimal, ...). It returns an array of the same type and size as the input parameter array.[code]...
