I know how to create a file, but would it be possible to create multiple files? the number I would like to create is determined from the number in a textbox, i.e., if the textbox had 2 then I would create 2 files, if it had 5 then I would create 5 files.
My code to create file
System.IO.File.WriteAllText("C:\Test.txt", "")
I am running batch jobs on a job scheduler. One of the step is called 6 times so that we can execute the step parallely (to utilize the max server resource and to execuet the step in less than 2 hours rather 6hours). At the end of each instance it has to create a text file (6 instances = 6 text files) and the next job in the queue only runs when it could find all six files,
I am trying to create 6 dummy text files using vb.net.
1. to create a text file like file1.txt, when each instance of the step is completed running and it should exit the code after a file is create.
2. In this manner the code is executed 6 times and it must produce 6 files like file1.txt ....... file6.txt.
right know the maximum code i could write was ( and this is not correct)
Public
Function CopyFile1()
As
Integer

I'll explain what I'm working to eliminate the assumptions of a brute forcer. I'm working a Random SQL Data generator. What I need is a way to create a multi-dimensional array from multiple word lists, 1 dimension per word list. I have tried a few different things and nothing I've tried works. However, I have got it to work with a single word list and an array of 1. I figured there is a more efficient way of doing this than writing a massive block of select case and using multiple 1 dimensional arrays, this would end up very messy and inefficient it seems.No this is not for homework, this is for personal learning use only.I would post my code, but like I said, nothing I've tried comes close to working.

It would be wonderful if i could setup a custom menu programatically as well. I have seen some documentation on Imapi 2.0 but i have not been able to find too much suppoert for it. I have also found a few SDK's out there but most are over $1000 which just isnt in the budget.
1) Is there a library included in windows 7 that will allow me to do this.
2) Is there an inexpensive or open source sdk with good documentation out there to do this with
I 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.

Having a slight permission problem with Win 7 I am guessing it will be the same on Vista but work fine on XP (yet to try)But my program is sitting in: C:Program FilesCompanyProgram And its trying to create new files alongside itself in the Program Files area but bombing out which I know is permissions. If I go there to create the file myself it comes up with a UAC prompt and when I hit allow it works fine but obv the program can't do that byiteslf so bombs out.Is there anyway I can over come that without the user having to grant admin rights to the program each time it starts or do I have to write data to another place?
View 4 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 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.

I have many applications that create TLB files which I guess are so that vb2005 can comunicate with the DLL files. Now what I would like to do is have all my TLB files in one folder and have my application point to that folder to use them.The problem I am having is that my EXE will not run unless all the TLB files are in the same folder as the EXE. I do not want this. I want to put some code into my file that sais that the tlb files it needs are located in say: [code] and still have it work. again right now they all have to be in the same folder which is really bugging me.
View 3 RepliesIf I have a large number of classes, each similar to the other in certain aspects (they all share a common base class, but each does things differently), and I need to create Windows forms for each to allow easy changing of their values through a GUI? Create one matching form for each object in VS' forms designer, Or Use code to create the forms dynamically at runtime.
#2 makes the most sense to me, because a lot of these objects will share very common features of the form, notably "Ok" and "Cancel" buttons. But one object might need to draw a textbox on the form while another might need to draw a combobox. Not to mention, if I want to put icons on the "Ok" and "Cancel" buttons, I'd have to do this for each copy of the form in designer, and that sounds like it could get out of hand quickly.But is drawing forms through code sane? VS' forms designer is pretty sophisticated and designed to make life easier. Am I wise to consider ignoring its functionality and diving into the trench warfare of forms design through code? Or are there examples of automating form creation based on an existing object's properties?

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:

WC.DownloadFile(URL, Location)
RaiseEvent FileDownloadComplete()
Return True
Catch ex As Exception
RaiseEvent FileDownloadFailed(ex)

Can I modify this to allow downloading of folders too or will I have to use a completely different method?

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?
