Making a system to check for files existing in a network (for our tv address system, pawn shop stuff)Anyway, the command1 checks if d1.txt exists, then d2.txt and fills out the boxes, Instead of 10000 if statements?
Below is example of my current code
Private Sub Command1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Command1.Click
If My.Computer.FileSystem.FileExists(Text1.Text + "d1.txt") Then
d1.Checked = True
[code]....
Basically it's a bunch of check boxes, that check if the corrosponding file exists
Is there a tool in the toolbox that i can use that replaces checkboxes. i have limited amount of space and checkboxes just keep taking up room. I need the user to select multiple objects like checking multiple checkboxes.
How can I check for multiple instances of my visual basic application? When the user runs the application, I want to know how many instances are already open.
I have this code for checking if 1 file exists (binPath is already declared):
Dim filename1 As String = "OpenSim.Grid.UserServer.exe" Dim U As Boolean = System.IO.File.Exists(binPath + filename1) If U = False Then[code]....
However, I need to check if another five files exist too. Should I just copy the above code another 5 times, or is there a more efficient way of doing it?
I was wondering if it was possible to check if the file "test.txt" is open? and if so then display a message that the file is in use? My biggest problem is that the file can be opened in notepad, word, excel etc. I have some basic coding, which checks if the file is open - what I am trying to do is check if the file is currently open and if its not in use then proceed with the coding, I have the following coding so far.
Dim Process() As Process = System.Diagnostics.Process.GetProcessesByName("notepad") Dim Process2() As Process = System.Diagnostics.Process.GetProcessesByName("word") For Each p As Process In Process
I have 5 checkboxes in total.I want to check how many checkboxes have been checked.I dont want to write checkbox1.checkstate,checkbox2.checkstate and so on...How do I accomplish this effectively?
I have added reference to few dlls in my VB.net Project. When I check into Visual source safe and get latest version from another machine, VS.net 2008 throws errors.I have to add the references again in that new machine. Is there anyway where I can keep the references in spite of files checked in to VSS?I need to send copy all the files to production server and we don't have VS.net on the production box to add reference and build the application.
I've never really used the Check List Box in the past, however, for the recent program I am developing, I am using this control rather than individual check boxes scattered across the form.Anyway, I want to be able to program through code which items get checked in this checked list box. Specifically, I have a variable that contains the text of each check box that I want checked.With a normal check box, I can simply say:
Dim strNames As String strNames = "John Doe, Mark Johnson, Mike Brown, Cindy Smith" If strNames.ToString.Contains("Mike Brown") Then[code]....
Unless someone knows of a way to do this already in windows, what's the best method for (using a background worker) checking all of the files & subfolders in a folder against another folder in an external usb hdd?
I'd like it to copy only the files that's changed since the last backup, and it'd be nice if I could right-click on a folder (which i can easily google this one, it's a common thing) and select my program and it'd pop up a window to get the destination (since the source is known from the windows context menu) and only copy (overwriting the existing files/folders) that've changed since the last backup.
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:
A site map for each web.config file - don't know how this will work Removing the sub web.config file to only use a single one
I know this is out there and probably illogical but I was wondering if it was possible to take multiple picture files and compact them into one file.... and then retrieve them from the program later? Way to combine any amount of image files into one file
Module Module1 Sub combine() Dim img1 As New Bitmap("i1.jpg")
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.
(Also, this is the first program I've written since about 2005, and I'm essentially teaching myself VB as I go. If you'd like to see what I've cobbled together so far, you can find the program here.)
I'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.
When user stores a record, I need to make sure dates don't overlap.My simple code checks date ranges within a specific record (e.g. user enters 9/16/2011 or 10/21/2011, I throw an exception.)But, on the slim chance a user gets creative (e.g. 10/14/2011 - 10/23/2011 or even 10/14/2011 to 11/16/2011), now they have circumvented my check.BTW, the user could enter 10/14/2011 to 10/23/2011 if they were editing the record that contained values 10/15/2011 - 10/22/2011.So, I'm trying to solve this riddle with a linq query. However, what I have isn't working exactly right.
UPDATE Nevermind about code not working. While trying to provide an example to expand on Miika's repsonse, I found my answer. So, giving credit to Miika for pointing me in the right direction and posting my working code below:
Here's my code:
Private Sub CheckForOverlap(myMonth As Messages.MyMonth) Dim am As New MyMonth() Dim amCollection As Messages.MyMonthCollection
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 trying to associate multiple files with my app i have done associating files but when i try to open multiple files app open just one file, to open the file iam using this code in form load event
For Each arg In My.Application.CommandLineArgs open_File(return_rtb, arg) Next arg
And the second problem is myApp is single instance app how to catch if user double click on a file while myApp is running like form load event for first time.
How do I combine multiple files into the one file with a new extension. No need to be compressed. So I avoid Zip or similar solutions. (Actually don't want to add third party solutions into my application.)
I know you can copy a file using:[code]The only way I know how to copy multiple files is by using a for loop, but if you choose to display a dialog box, you get a dialog box for every file you copy instead of one showing the progress of all the files.So with that said, is there any way to copy multiple files, and only have one dialog box displayed?
I was trying to do something like this (that worked with the Kill method of VB6) System.IO.File.Delete(OrderInfo.ParentFolderPath & "NJ0*.DTA") because there are several files that start with NJ0 and end with .DTA
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
I 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 am trying to upload all files in a folder using the FTP method below... I just can not figure out how to pass the list of files in the folder to the FTP method which works great for single files
vb.net UploadFile(filetoupload, uploadpath, My.Settings.User, My.Settings.Pass) End Sub
[Code]....
with the aim of generating a list of files in the folder and then looping them though the ftp method, currently have a Error1Value of type '1-dimensional array of String' cannot be converted to 'String'. error based on above code
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 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?
