Hey guys!
\r\nFirst: THANKS FOR THIS NICE LIBRARY! Really, much better than using external apps.
\r\nSecond: I've read the documentation. But I don't know enough VB.net to really understand it all. I'm doing the following:
\r\nI'm creating a backup tool for a fixed folder. It don't change its location (apart from user profile folder), but the files inside it can change. And are a LOT of files, all of them really small. I've created almost everything: the forms,\r\n the controls, the savefile dialog and all. Now I want to add a progress bar that will increase after every file has been compressed, but I don't know how many files it has! And the maximum length of the progressbar will be the number of files, but I'm compressing\r\n a directory, not the files itselves.
\r\n
\r\nHow can I do this ? The lib can list all files and do a step everytime a file has been sucessfully added?
Thanks in advance!

\r\nThe example code seems very hard to understand to me, I didn't got it. I think that a variable that recieves how many files the folder has can do it easily, but I don't know how to set up this variable. Someone can help me?

\r\nYes, to show a progress bar for zipping up a large set of files, you need to know the number of files being zipped.
\r\nIn DotNetZip, normally you would call a method like ZipFile.AddDirectory(). This adds entries for all the files in the specified directory into the ZipFile object. How many files is that? Easy: reference ZipFile.Entries.Count(). This\r\n is the number of entries that will be saved when you call ZipFile.Save().
\r\nYour progress bar logic should be attached to the SaveProgress event generated by DotNetZip. You can attach that logic after you call AddDirectory().
\r\nDoes this help?
\r\nGood luck.

Helped a bit, but I don't know how to make it increase :P
\r\nMy code is here:
\r\n\r\n
Imports System.IO\r\nImports Ionic.Zip\r\n\r\nPublic Class Main\r\n\r\n 'Definie as vari�veis\r\n Dim NomedoBackup As String\r\n Dim Pasta As String\r\n Dim NomeAntigo As String\r\n Dim NomePadrao As String = "c:\\profile.zip"\r\n\r\n 'Captura a pasta do perfil do usu�rio\r\n Dim Perfil As String = Environment.GetEnvironmentVariable("UserProfile")\r\n\r\n 'Captura a localiza��o da pasta 'meus documentos/documentos'\r\n Dim Documentos As String = System.Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments)\r\n\r\n\r\n Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load\r\n\r\n 'Define a pasta a que ser� comprimida\r\n Pasta = Perfil & "\\AppData\\Local\\Criterion Games"\r\n\r\n End Sub\r\n\r\n 'Janela procurar arquivo\r\n Private Sub Procurar_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Procurar.Click\r\n\r\n\r\n 'Cria a janela de procurar arquivo\r\n Dim Salvar As New SaveFileDialog()\r\n\r\n 'Pasta inicial\r\n Salvar.InitialDirectory = Documentos\r\n Salvar.Filter = "Zip Files (*.zip)|*.zip"\r\n\r\n 'Detecta quando o OK � pressionado\r\n If Salvar.ShowDialog() = DialogResult.OK Then\r\n\r\n 'Define o nome do arquivo\r\n NomedoBackup = Salvar.FileName\r\n Caminho.Text = NomedoBackup\r\n NomeAntigo = Salvar.FileName\r\n\r\n End If\r\n\r\n End Sub\r\n\r\n 'Bot�o de backup\r\n Private Sub Backup_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Backup.Click\r\n\r\n 'Garante que n�o ir� gerar erro verificando se a vari�vel est� vazia\r\n If NomedoBackup = "" Then\r\n 'Define um nome padr�o\r\n NomedoBackup = NomePadrao\r\n\r\n Using zip As ZipFile = New ZipFile\r\n 'Define a compress�o para a melhor poss�vel\r\n zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression\r\n 'Adiciona a pasta previamente definida\r\n zip.AddDirectory(Pasta)\r\n 'Salva o arquivo\r\n zip.Save(NomedoBackup)\r\n End Using\r\n\r\n 'Mensagem alertando que nenhum nome foi definido\r\n MsgBox("You didn't defined a name for the backup. By default, it has been saved to: " & NomePadrao, MsgBoxStyle.Information, "Warning!")\r\n\r\n Else\r\n Using zip As ZipFile = New ZipFile\r\n 'Define a compress�o para a melhor poss�vel\r\n zip.CompressionLevel = Ionic.Zlib.CompressionLevel.BestCompression\r\n 'Adiciona a pasta previamente definida\r\n zip.AddDirectory(Pasta)\r\n 'Salva o arquivo\r\n zip.Save(NomedoBackup)\r\n End Using\r\n End If\r\n End Sub\r\n\r\n\r\nEnd Class\r\n\r\n
It doesn't refer to any progressbar because I removed it since I didn't knew how to work with it :P I have another question... how can I embed the DLL into my app and use it from there? I've searched a bit, but none seems to be clear :)
\r\n
\r\nAnd thanks for the response. I was almost losing my faith that someone would reply!
Regarding embedding assemblies, see this question and answer: \r\nhttp://stackoverflow.com/questions/222655/embedding-assemblies-inside-another-assembly/625115
\r\nRegarding the progressbar, you need to use a SaveProgress event.
\r\nSee this documentation: \r\nhttp://cheeso.members.winisp.net/DotNetZipHelp/html/2b8624b0-6823-7e33-a864-2c7bbd9835e7.htm
\r\nThere are also examples in the DotNetZip source distribution.
\r\nYou can also look in the example code here: \r\nhttp://code.msdn.microsoft.com/DotNetZip/Wiki/View.aspx?title=VB%20WinForms%20Example
\r\nGood luck.

\r\nI'll only now rename all variables to names that make sense to me, so it will become even easier to understand (:
