[URL] There's a RemoveEntry() function to remove a file, but I can't seem to find a function to remove a directory... Does DotNetZip support directory removal? If not, what are some other libraries I could try?
View 1 RepliesOk, I have a usercontrol in a Class Library Projects which contains a Button, 2 Listboxes, and a Progress bar. My code is to look for a file and if its there post to one listbox and fill in the progress bar and also put the programs current task in the other listbox. Recently, I started using VB.Net 2010 Express and wanted to turn part of a form into a .dll so it would be easier to update. I started getting a error and had to declare a variable as a New instance of UserControL1 (my user control). When I did this, the control would run, but the Progress Bar doesn't fill and neither of my listboxes show anything. What Should I do?
View 1 RepliesI have the following function
Private Function GetMD5(ByVal file As String) As String
Dim md5 As MD5CryptoServiceProvider = New MD5CryptoServiceProvider
Dim f As FileStream = New FileStream(file, FileMode.Open, FileAccess.Read, FileShare.Read, 8192)
md5.ComputeHash(f)

It works fine, but when working with very large files on the network my users sometimes panic.I'd like to add a progress bar that updates based on the progress of the hashing through the file.So, my choice are either to manually create the hashing process, which I believe will be much slower,or somehow tap in to the position value of the filestream and use that to update a progress bar.I'd be happy to tap into the events of the MD5CryptoServiceProvider if I could, but I don't see anything there.I have searched the net to try to find an example and have only found code that works by reading line by line from the filestream, not from it being passed to another control/service.
Looked through many tuts, can't find one.
View 1 RepliesI'm currently working on a utility software, file compression, with VB.Net. And using an open source library to compress and decompress files - DotNetZip - and already running.
My friend told to make it unique and not traditional, that I make the output compressed files cannot be opened with other compression software. Now my question is... is it possible that way? Using an open source library which the output format is ".zip"?
I first thought that changing the file extension of the compressed file to unknown format so it can't be opened when you try to decompress it, unfortunately, using the "Open With..." function of windows it could still be decompressed.
Is it really possible? OR what other features can I add that WinZIP doesnt have yet? I compared my work to WinZip since the same output is ".zip".
In ASP.Net two of the possible ways to make the zip files are
Sharp Zip Library
Dot Net Zip Library
How can i use any of these in Classic ASP to make the zip files ? And which one will be better ?
Ive found plenty of examples of extracting an icon from a dll, but then those examples display the icon as an image, which is not what Im trying to do. Im trying to extract those icons dynamically into my program to set the application icon, and other icons for items on the menu bar. I have this little bit of code, but I keep getting various errors when I use it.

I've made a working progress bar but I'm trying to make it show a message showing 'loading complete' or something when it is 100% finished.[code]but this resulted in the message opening constantly and when they are all closed they stop opening?

I'm creating a dll (class library project) file for an OCX. I have an OCX (not Active X, just normal ocx and no need to put on form in order to use it.) which I normally call it from normal windows project's code behind. However, in order to use this OCX, I need to install one software and register with the correct license key.

View 10 RepliesI�m using a few workbooks in excel to calculate data and then I import them to access and finally I use it in visual basic front end.
Now the workbooks can get quite heavy and it takes some time for the computer to open and save and so on, so I�ve put a progress bar on my form to show the user that something is happening.
However I would like to use excels own progressbar, so that when the workbook is being saved, my app actually shows the progress of that particular save. Can I do that? The instance of excel that handles the workbooks is hidden.

I just converted a project from 2008 to 2010. I didn't encounter any errors in the conversion.I tried to add HTML Imports System.Threading.Tasks. This gives the "...doesn't contain any public member..." warning and naturally, the .Tasks library is not recognized. Is there any trick to the conversion, setting in the properties, etc. that I need to deal with?Note that I have a "from scratch" project that accesses the System.Threading.Tasks class with no problem. Both projects are contained in the same Projects folder as in:
