Any Way To Add Files To List Other Than One At Time?
Oct 8, 2009
I am building help files for a program using HTML Help Workshop.I have been trying to manually add files to the project file list as I write them, as HHW doesn't do so automatically.But it doesn't seem to matter whether the files are included in the list or not.When I compile, it tells me if any are duplicated, but it doesn't tell me if any are missing.(I have deliberately removed some to see if it makes a difference, so it's not that I haven't left any out.) And, whether they are in the list or not, the compiled help seems to find the files it needs.What is this list of files for?What files need to be included in it - html, css, images, maps? Why doesn't it seem to matter if my files are included in it or not? Is there any way to add files to the list other than one at a time? (e.g specify an entire folder?
The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:
Year 1: $1,290.93 Year 2: $2,724.32 Year 3: $4,350.76 etc....
I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:
Public Class frmFutureValue Private Sub btnCalculate_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles btnCalculate.Click
I have a webserver and I upload files to my webserver from time to time. I have an ftp account which points to public_html that is main directory.
I though why give full access so I created another ftp account (e.g. test) which points to a specific folder. Now when I try to upload a file using test it fails.
For e.g.
the following code works: My.Computer.Network.UploadFile("d:ok.txt", "ftp://mysite.com/Test/okay.txt", "main@mysite.com", "mainpw")
- this is because this a/c has access to root folder of website
i am trying to create a list of list in that i would like to work on multiple accounts at the same time. lets say i have 5 accounts. every account has a seperate name. each account has a few fields. so i though of having a list of bookkeeping (with 5 accounts) and a list of accounts (with expense, income, tax, status, etc as fields). [code] and if the idea of using list of list works how do i loop through both lists.
I wrote a program to download and play AVI files the files are large in size and long time wise. I have the files playing as they are being downloaded but i can't see how long the file is or seek reliably. i was reading that the AVI headers are in the last 512kb of the AVI file *why would't they put it at the start* lol so my question is is there a way to download the last 512Kb of the file i'm downloading. i have the Bytes Read and Length of the file while its downlaoding i'm just not sure where to go from there, or how to do it atleast. If i had the length in time of the Avi file i could set the trackbar to be able to seek properly. or if someone has an idea how i could get the time of the video by using fps and some math i could prob do it that way too but idk how i would tell how i can find how many kb are in the fps i'm sure it changes so think that way is't going to be reliable. how to get the last 512kb would be the best option not sure if it can be done even.
I am trying to create a program which will read the files that exist in a directory, and then write in a text file the specific information (full file name, date created)i have found several code in the site but i cant make it work, the machine i am running the code is XP and i am using VB2008.The code i have found is the following:
I have a SQL Server table with a list of files (path + filename), and a folder with multiple layers and files in each layer. I'm looking for a way to reconcile the two without having to process the list twice. Currently, I'm doing this:
For Each f as FileInfo In FileListFromDatabase If f.Exists is False, mark it as deleted in the database Next
[Code]....
Is there a better way to do this? I'd like to avoid converting all the matching files (of which most will be) to FileInfo objects twice. Since I'm a T-SQL developer first, I'm picturing something like an OUTER JOIN of the two lists where they don't match. Something LINQ-ish?
ListBox1.Items.Clear() Dim di As New IO.DirectoryInfo(TextBox1.Text) Dim aryFi As IO.FileInfo() = di.GetFiles("*.*")[code]......
and that displays only the file name, like text.txt but i want it to display C:/Text.txt and all the files in the subfolders too, like C:/Program Files/Test2.txt but i just get test.txt from only the c:/ .
I have List (of class). having 1800 of count and each object has 90 properties. When I terate earch with 90 properties taking more and more time. How to resolve this
Dim cellIntStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle cellIntStyle.DataFormat = HSSFDataFormat.GetBuiltinFormat("#") Dim cellDateStyle As HSSFCellStyle = hssfworkbook.CreateCellStyle
is there any way to copy multiple files at the same time WITH PROGRESS BAR like in windows explorer? I am using system FileIO.FileSystem.CopyFile for copying single file, but I want to do this with more then one file.
I as seeking to move 10 file every 10 minutes from one folder to another using .NET (vb c#) I am was thinking that i could of achieve this with LINQ query, but i cant get my head around this would there be a solution with LINQ or otherwise that can select the last 10 files form or top 10 files. so that i can move only these files from Directory1 ( the big pool of files) into director 2 ( a smaller more manageable pool of files).If all fails- then i wll manually have to copy or cut to at a time.
I have a button when clicked unzips a file in a located folder. This code unzips one filename at a time.
What I want to do is unzip all files in a folder at one time.. assuming the folder has been selected and the target folder selected too...
The code to unzip each filename is shown below...
Code:
Private Sub unzip(ByVal filename As String, ByVal targetdir As String, ByVal overwrite As Boolean, Optional ByVal password As String = "") Dim inputStrm As New ZipInputStream(File.OpenRead(filename))

I'm trying to get an in a loop to accept a value and add it to a list each time okay is pressed. For some reason, I have to add a value twice for the input to be added to the list. For example, if i enter the string "hello" in the inputbox and click okay, it doesn't add to the list, but if i do it a second time, it goes in.
Here is the code for it
Do Until lstCourse.Items.Count = CDbl(txtClasses.Text) InputBox("Enter Course Number", "Course Number") strCourse = InputBox("Enter Course Number", "Course Number") lstCourse.Items.Add(strCourse) Loop
ok.. just as it sounds.. I'm kinda making a document portal app for work.. has 4 list boxes going to 4 different drive locations.. for cosmetic reasons I want only the last box you clicked in to show a selected item.. so if you selected box 1 item and it was hilighted and then you went to box 2 and selected something I wanted box 1 to then dissapear.
I have some code written to handle this.. but its not working so well.. since I use the SelectedIndexChanged trigger to fire off another piece of code to unselect all the other windows.. those listboxes fire their triggers also because I have to call lstWord. SelectedIndex = -1 to make it not have something selected anymore.. and when you do that.. it calls its SelectedIndexChanged and ends up deselecting everything.. so wasnt sure if anyone had done something like this before.. seems like something that would have been done before.. but as you can imagine searching the web for "multi list box select only one at a time" or something similar..gives you some strange results..
I need to figure out how to read a TXT file as an input type and read it one line at a time, but instead of displaying the text,it will find a keyword in the user typed text and display an answer from the text file. I already know how to do everything but get it to read the input file properly, line by line.
I am just trying to get all files into listbox from directory and subdirectory but i use the coding which run and not giving any error but it is not picking any files from the directory. I dont know why
I am trying to create a list that will add information each time someone submits the form. I keep getting the error:Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index..I know I am getting the values passed from the Class since I can output it to a message box. But when I try to create the index it crashes every time.[code]
I have a list of web pages that load into a CheckedListBox at run time.These pages are user selectable.
Scenario One: Single Selection.The application loads the selected web pages and parse's the content, this could take a short time, or it can take a few minutes.No problem here. I am using a BackgroundWorker to perform the parse.
Scenario Two: Multiple Selection My query relates to a method that I can employ to deal with iteration of the CheckedListBox to process the next selected web page back on the UI.
I need to wait till the BW has finished before we can move on to the next page.I'm sure the above example is not best practice to hold up the UI's iteration of the CheckedListBox, until the current web page is processed.
Is there any way to download multiple files at the same time from a remote server? How I am doing it currently is I get a list of files from the target folder on the server then I loop through that list & download each file 1 at a time. For 100 small files it takes about 45 seconds. I'm guessing that the bulk of the time it takes is logging in to the server for each file to download, so 100 files means it has to login, download & logoff 100 times. Is it possible to login just once, download the 100 files then logout?
I have a Datetimepicker, when i select a date it brings up in a listbox all the files created on that day but in no particular order. So i wanted it sorted by when they were created (not to fussed either ascending or descending). i tried using the code below with no luck, This adds multiple of blocks of the same files on the selected date
