File I/O And Registry :: Zip Large Number Of Files?
Aug 28, 2009I 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().

Jun 11, 2011I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.
What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.
Here's the code I've written that successfully imports the data and displays the first column:
Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dataCountry As New DataTable()

Should I perhaps use something other than a list view?

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, 2011I 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.

Selecting Random Number From ComboBox?
May 15, 2009The problem I have is I have made a program which you select a value from a combobox and it changes the value of a url for a picturebox and thus changes the picture, I also have a button which randomizes all of the comboboxes so I will get something unique, but every time the program loads, and I hit random, it chooses the same numbers in order. If you need an example, when I press random the first time I get the number 7 for my first combobox, so the selected index=7, every time I load the program and press random it picks 7 for that combobox.

View 16 RepliesConverting Time Formats Displaying In Label On Screen
Sep 24, 2009I have a variable which I called ElapsedTime. I press a button and it displays the time in seconds since clicking the button, into a label . I did it with HTML
Private Sub Timer2_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer2.Tick
LblElapsedTime1.Text = ElapsedTime
ElapsedTime = ElapsedTime + 1
End Sub
Private Sub BtnStart_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles BtnStart.Click
Timer2.Enabled = True
End Sub
This updates every second a bit like a simple stop watch. Great so far, because I do need the elapsed time (in seconds) for later use in my app. However, whilst elapsed time is being displayed in this label on the screen I want it to be shown in HH:MM:SS format. How can I convert it into a new variable " ElapsedTime2 " so that I can show it in the desired format yet still retain my original " ElapsedTime " variable for later.

WM_GETTEXTLENGTH Returns (too) Large Number?
Aug 26, 2010I am using VB Express 2008 and want to return the titlebar text of a window This is what I have:
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" (ByVal hwnd As Long, ByVal wMsg As Long, ByVal wParam As Long, ByVal lParam As String) As Long
Private Const WM_GETTEXT = &HD
Private Const WM_GETTEXTLENGTH = &HE

This should simply return the window name I.e. "Calculator"But debugging it i get an "OverflowException" on:
strtmp = Space(length - 1)
If I look in the length variable it has "8975925931411505153" in it Why is it so big, and why is it not just "10" for the number of characters in calculator?

View 5 RepliesExtract A Large Number Of URLs From A Site?
Dec 18, 2010I've a situation where I am trying to extract a large number of URLs from a site, but the site which provides the URLs has an obstacle. Rather than the link directly to the site, they provide a link to an internal page, which automatically redirects me to the URL I need.
i.e.
<a href="www.StartingSite.com/outgoing/1234" ...> Example.com</a>
which passes me to an internal page, then automatically routes me to Example.com
I've suspected if I can do this, it would be through cookies.
Perhaps a little more work, I could create a page which calls each page, then I could acquire the URLs from my history, but my browser would crash for the # of URLs I'm extracting.
any means I could gather the end URL of this link?

View 5 RepliesLocalizing Large Number Of Windows Forms
Oct 12, 2011I'm working on a project that involves localizing a large number of Windows Forms. We're dealing with layout using the TableLayoutPanel control, which works nicely. One area we're striking problems with is when we set the Form.Localizable property to True, we then end up having to manage one .resx file per form per language.
That would be fine if the .resx files only contained the Localized text, but it also contains a vast amount of layout data for the form. Is there a way to separate the localizable text elements from the control layout information, that continues to work in the visual studio IDE? I've noticed that I can modify my the form's designer file to look at another resource file, but when I use the form designer, these changes are deleted:
'Label1
Me.Label1.AutoSize = True
Me.Label1.Dock = System.Windows.Forms.DockStyle.Top
Me.Label1.Location = New System.Drawing.Point(3, 0)
Me.Label1.Name = "Label1"
Me.Label1.Size = New System.Drawing.Size(61, 13)
Me.Label1.TabIndex = 1

Slow Form Load (has Large Number Of Controls)
Nov 9, 2010I wrote last week about a problem with an MDI program that had a large number of forms (each with a large number of controls on it) that was "sluggish" in loading and in switching between the child forms.I've attached an example program in VS2008 (though the actual app is VB2010)Rather than show the hardware control application with all of the text fields, and picture boxes acting as indicators, I made a simple program to show the point. This is exaggerated as this just loads 2000 or so text boxes on a form. In the real app I have ~ 200 assorted controls per form of picture boxes, scroll bars, text boxes, labels etc. Also, there is a large full screen .jpeg as the back ground of each form. All are generated at run time and are placed on the form in the New call of each form. (as in the sample attached)main issue seems to be the methodology I use to switch between child forms. I make the current form .visible = false, and the next.visible = true. I have used this as it "keeps the place" on each page if the user has scrolled or is looking at one section of the form. When the next form .visible = true happens I see the controls added in a "machine gun" fashion instead of all at once.
