View 1 RepliesI 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().
So i created resource file New --> new file --> Native Resource Template Then added icons with custom id, like "x", "u_100", .. so i understand, what the files (in my case icons) is..

I'm creating a number of textboxes, all calling a function during the onchange event to update their value to the database. These boxes are dynamically created in the backend because the data changes based on specific criteria that can be changed on the page. Here's the creation of the boxes:
Dim t as TableRow
tC = New TableCell
Dim txtBox As New TextBox

When I enter a number into the Textbox, the event fires as expected, but it fires twice.
I want to make an application that's pretty much all server side. I have everything sorted, apart from downloading images from my server. I have a listbox containing all the game names, in this format.
pacman
rallyx
mspacman

There are many more, that's just an example.
Each game name is stored as a folder on my server. Inside those folders is the games boxart, called boxart.png. What I want to do is make an application that makes those folders and downloads the images. I have made the "create a folder for each game name" code already, now I just need to add another line or two to download the image inside those created folders.

View 1 Repliesim new to coding (started coding last month) so im a little stuck on how to do this, im making some emulation programs to learn coding with, and a part of it is to point the app to a .iso/.bin file and scan the data inside of the iso/bin to check if a file exists.[code]My issue is i cant find any class examples, or any information etc on how to code it so my application can see the data inside of the iso/bin instead of just see'ing the iso/bin file, so that i can then check the data inside the iso to see if the file exists etc.Im a novice still at coding so making a new class myself to look inside the iso/bin is to complex for me.
View 1 RepliesI have some variable that when divided I get this symbol: -1.#IND when you look at the variable in debug. This only happens when I put the equation in the Dim statement.

I don't have a problem. Why when I put the equation up in the declaration area it sets it to -1.#IND (I assume this is infinite or NAN or some such). I'm curious as this is the only time I've had difficulty with this.
I'm very new to programming with Visual Studio(just a few weeks). I've read through a beginner's book and I've started to write my first little programs to get used to coding and to improve my skills. One of the first programs I had created was a simple currency converter. I've created a list box and a combo box with a number of different currencies in them and I want to know if there is an easy way to attach a value to each of these selections. For example, if someone selects British Pound in the list box and Indian Rupee in the combo box, I want to be able to have the British Pound be worth 1.67(versus the dollar) and the Rupee to be 25.00(versus the dollar) for example so that I can create a simple function that will change pounds to dollars and then to Rupees so that I can do this calculation with a multitude of currencies. If you have some idea of how I can attack this problem,
View 2 RepliesTo improve performance, when one has many files to readwrite it is better to save them in smallergroup in different folders. Is there a magic number over which it is better to start splitting the folder? for example below "10.000" (invented number) files can be stored in one single folder, while above that it is better to start storing files in multiple folders.
View 16 RepliesI have an app where a user enters information on a ticket and that ticket is saved off to a file on a share.Later on, when the ticket is closed or resolved, the file is deleted.Pretty straightforward.The below code is used to achieve this but, and this is the odd part, I'm finding that sometimes the app does not write the file and other times it will not delete it.I've confirmed that the user is running the latest version, that the tool isn't in off line mode, that all the appropriate criteria are set to true before entering the routines. It works 99% of the time but every so often it doesn't create/delete the file and there are no errors thrown or anything.Going into this section of code, chkOffline is not checked, "GoNoGo" is set to "Go", "Type" is set to "Live" and all fields have been filled out on the form(and vetted).What's more, there are other actions earlier in the app/sub that rely on these same conditions and those actions are getting carried out.[code]
View 2 RepliesI've been having a very odd problem when creating zip files in vb.net. They are ok when I run the code and save the file locally. However, if I run the program via remote desktop, and then save locally, the zip file is corrupted, and will not open (message "cannot open file:it does not appear to be a valid archive").I have tried opening it as a txt file, and found that there is a load of HTML at the bottom of the corrupt version, that the non-corrupt version does not have. Anyone got any idea how this extra HTML might have got there?[code]
