I have this code so I was wondering how do you put in multiple files: E.g:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If System.IO.File.Exists("C:fileiwannadelete") Then
My.Computer.FileSystem.DeleteFile("C:fileiwannadelete")
End If
End Sub
I am trying to create a program that can upload many files at a time to an FTP site. I don't want to use a dialog box. I want to be able to specify a certain requirement in my code (for ex. all files that begin with "abc_"). I was able to find a lot of code online for uploading a single file, but all the code that I found for mulitiple files were either very lengthy or done by bringing in a new library
View 1 RepliesI'm new to the .NET platform (old-time ASPer) and for a project have a simple pair of .aspx scripts that take some querystring data and process it. They both make use of the same Subs, Functions in them, so naturally I'd like to move the code to a common resource.vb file. Having done some reading, it looks like my options are a Code-Behind type setup, and placing the Subs, Functions in a .vb file and placing that file in App_Code.So, the Code-Behind model doesn't seem to make sense here, as the functions are shared by both files. Placing the Subs and Functions in /App_Code/resources.vb and I am getting the following error when trying to call any of the routines:
View 2 RepliesI am trying to create a sort of code library in visual basic where the form displays a list box of certain project files in vb that i have made in the past and when clicked, launches the .exe files of those visual basic program project files.I know it does not work the same way as writing/ reading text files to vb and it seems as simple as 'on click, launch .exe of selected string "vb program 1" and so on. I am having trouble getting started on this one. Im sorry I cannot provide any starter code bc I only have a basic understanding of in/out text files which wont work the same way with .exe
View 1 RepliesI have a website that has highly granulised access and hence requires many web.config files. The problem is I would like to trim the menu so that only certain users will have access to certain folders. I have enabled trimming and setup roles in the sitemap, however when I access the page the menu is not show, as I am authorized to view the default page which is not in a subfolder. When I type the url of a page in sub folder's I have access.
How should I handle this:

I'm developing an application to help law enforcement retrieve and analyze logs and other files left by the use of Pidgin (a multi-protocol messenger client). Right now I'm nearly done, but I want to add the ability to search chat logs for user-defined words or phrases and I don't even know where to begin.
Chat logs are stored as html documents in a folder/sub-folder/sub-folder/sub-folder fashion, where each sub-folder can have dozens of sub-folders inside of it, and the final sub-folder can have dozens if not hundreds of chat logs. If anybody could point me in the right direction, I'd be very grateful.

View 2 RepliesI'm trying to copy multiple excel source files into one excel file. My current code is working only for 3 source files..If more than 3 files are there, it doesn't copy the data but creates blank work sheet in the output excel file. Lets say I have a source folder with 5 excel files. Each workbook contains one worksheet with data. It copies upto 3 worksheets along with data into output excel file.
Lets say excel1 contains A as work sheet, excel2 contains B as work sheet ,excel3 contains C as work sheet ,excel4 contains D as work sheet ,excel5 contains E as work sheet .Now my output excel file should look like..OutputExcel with A, B, C, D, E along with respective data.But my current code is giving output as A,B,C worksheets along with respective data but its creating blank sheet1,sheet2 in place of D & E.

How to comment multiple lines of code/block of code in VB?
View 5 RepliesWondering if it is possible. It works on the idea that all files share common code. The program would ideally analyse the source file and compare it to the reference files. It would then find common parts of the code and write it to a rebuild file. At the end the rebuild file and the reference files would then be able to rebuild the source file without it being present.
For Example.
source file code = xxyyzyzyxw
ref file 1 = xyxxzyzxwyy
ref file 2 = zxxwyzzywxx
The program would then analyse these files and make a rebuild file like the following
source(0,1) = ref1(2,3)
source(2,3) = ref1(10,11)
source(4,7) = ref2(5,6) + ref2(5,6)
source(8,9) = ref2(2,3)
Thus you would be able to build the source file using these instructions and the reference files.

I've come up with a way of downloading multiple files specified in a txt doc held on a web server. The problem is it only downloads files not folders, im using the following from the codebank to download the files currently:
Try
mCurrentFile = GetFileName(URL)
Dim WC As New WebClient
WC.DownloadFile(URL, Location)
RaiseEvent FileDownloadComplete()
Return True
Catch ex As Exception
RaiseEvent FileDownloadFailed(ex)
[Code] .....
Can I modify this to allow downloading of folders too or will I have to use a completely different method?
I'm trying to code a program that can download multiple files at once (on different threads of course). I have created a custom listview component that will allow me to add a progressbar directly to it. What my real question is, how can i take a url given by the user from an input box and create a new webclient to handle the downloadasynchronously
View 2 RepliesI am in the process of writing a windows service that will be replacing a vbscript that runs via a scheduled task currently. It currently runs on 350 kiosk machines in 350 different locations.Here is what the vbscript currently does:
1. The machine receives a ZIP file in the RECEIVE directory. Configuration_09122010_1234.zip. This file contains software configuration files that need to be copied to specified folders on the machine and to another machine on the local LAN where this kiosk is located.
2. The zip file is extracted to a folder with the same name as the zip file.Inside the zip file is an instruction file (.txt) and files that are referenced in the instruction file.
3. Opens the instruction file and performs the instructions in the file. Example: (this would copy pricingfile1.dbf to \mymachinecapplication1pricing, and then execute softwaresoftwarepatch1.exe which is located in \mymachinecpatches)
pricingfile1.dbf, \mymachinecapplication1pricing, copy
softwarepatch1.exe, \mymachinecpatches, run
4. Once all of the actions in the instructions file are completed, the folder where the zip file was extracted is deleted and the zip file is renamed to configuration_09122010_1234.zip.applied to show that it was processed by the script. Also, because the script is a scheduled task, this ensures that the file is not applied more than 1 time.
So I have started writing the service using the FileSystemWatcher. Basically I look in the receive folder for any file that looks like Configuration_MMddyyyy_*.zip and unzip it to a folder of the same name.
1. I have been doing some reading about the FileSystemWatcher Created event.I read an article about how the Created event fires as soon as the first byte is written but doesn't necessarily mean that the complete file has arrived at the machine. A post I read involved a .csv file and it mentioned that you try to open the file and catch any errors - if you cannot open the file, it hasn't arrived yet. This makes sense to me but I don't know what the equivalent would be to a zip file. It's not the same as opening a txt or csv file.
2. There are times that we send more than 1 configuration file in the same day, or even, at the same time. Above I mentioned the name was Configuration_<date>_1234.zip. The 1234 is a sequence number, always incremented. The idea is for 1234 to be applied before 1235 and 1236. So if I had 2 files sent *at the same time* and I want them to apply in order, how would I do this? I thought about when I am applying 1 file to stop looking for changes until after the apply process is completed, but then I *think* I would miss any file that arrived while I EnableRaisingEvents = false?

I want to have a backup feature which takes about 7 txt files and compresses/packs them into one file. Then if required at a later stage I can unpack all 7 files from the packed file. I do not need any compression as such just to make one file from 7, then 7 from from that one, if you understand what I mean. I have read there are some native libraries in .NET Framework 2.0 called DeflateStream and GZipStream. Can these be used?
