I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I am writing a 2D array to a text file.Is it digital map data, so I write each row at a time, and the format is readable by my map application.I have pasted the code below. The array is called edgegridArray. Everything else is pretty obvious. I don't know if streamwriter is the best way to do things,
Dim swr As StreamWriter = New StreamWriter("D:edgeoutput.txt") swr.WriteLine("ncols " & cols - 2) swr.WriteLine("nrows " & rows - 1)
I have a structure in memory which is working fine - now I need to write this entire structure to a file.The below code almost compiles, the problem is that "mstaRecordInfo" cannot be changed to a string, probably because of the Date field. I've just spent over an hour experimenting and searching the web but have gotten no closer to a solution
I am trying to print the contents of my array to a text file, but instead of just printing whats in the array it prints all indexes even if they are empty.
this is the code i am using..
Code: FileOpen(3, "garbage.txt", OpenMode.Append) Dim intCounter As Int16 For intCounter = strFirstName.GetLowerBound(0) To strFirstName.GetUpperBound(0)
I have an array of filenames, and an array of files in a directory. I use a for loop in a for loop to check if those files are in that directory. Look at the below code to illustrate my problem. [code]
I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?
I am creating a text file using a save file dialog and copying the path to the text box which file is used to write from vb.net. when i try to write i get an error "The process cannot access the file '....fileName.txt' because it is being used by other program".
The code is below
Public Sub writeInTextFile() Try Dim oWrite As New StreamWriter(TxtOutputPath.Text)
I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

Situation: I have a .csv file containing numerical values. I'd like to read the file and write the values to a 2-D array of the same form. Problem: I get all the rows of the .csv file written to a 1-D array. Looking at the code, I thinking I have the indexing for column and row positions incrementing properly but (besides experience in C#) I don't know what I'm missing. Below is the code accomplishing this.
I am trying to write a program that will use a Structure with <VBFixedString(4), VBFixedArray(10)> Public Test1() As String. Back in vb6 it was in the Type statement as Test1(10) as string *4 When I hit the line ".Test1(X) = TB1" i get the following error: Object reference not set to an instance of an object.
I'm reading a txt file into an array and then writing a new file one line at a time. The reason i'm using array is that i'm searching for a few lines that i want to find and replace.
However in my file I have some ascii characters but they aren't read well. I read something about System.Text.Encoding.Default but I don't know how to implement it in my code.
i have a form where there is a textbox where we can put the nameof the folder.and it wil put all the names of the folder in a text file say c:log.txt (but this is going to be in the background).
And in the foreground usercan select another folder.
This is my first post in the community. I am putting together a program that serves two functions:1. Takes input from TextBoxes and writes it to a text file.2. Takes the text from the text file and displays two specific strings of text in a MessageBox.This is the code for the button that writes the input to file.
Private Sub facSubmitButton_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles facSubmitButton.Click Dim facultyRecord As String = "C:\Documents and Settings\All Users\Desktop\teeny.txt"
When using .write method the string will be stored at the end of the text file. Is there a method that adds them on top? If not, how can I get this done without using too much memory and processor time?
I am working on a VB Console Application that takes an Autocad drawing type DWG and converts it to a PDF using a shell command that calls a third party application. In this case, acmecadconverter.exe from www.dwgtool.com. Then the PDF that is created needs a unique watermark, so I call a second application for that called pdftk.exe from www.accesspdf.com/pdftk/.
Everything works as intended, except when I try file names that contain spaces. The file system object does not tolerate spaces in the drawing file name. For instance, the following command gives me a system.io.filenotfoundexception...
My problem is i want to be able to write a url to a file. But there are a few problems.First one is the file is "unknown" to windows. Its the windows host file. which has no extension.second one is i need to write a line 21 lines down (making sure it does not over write any previously stored text. The line should look something like this
Write a program that requests a color as input in a text box and then determines whether or not the color is in the text file. The program should use the Boolean-valued Function procedure IsCrayola that returns the value True if the color in the text box is a Crayola color.
I am writing an application that must generate a plain Text file with fixed sized columns.my current code is:
Dim MyFilePath As String = Path & FILE_PREFIX & FileNr & ".TXT" IO.File.Delete(MyFilePath) Dim FileStr As New IO.StreamWriter(MyFilePath, False, <ENCODER HERE>)
I want to write a line into a text /.cfg file. the line is = name "ishtiak", i need a space between name & "ishtiak". the text "ishtiak" is loading from a textbox called textbox1. i don't want in the text box my name like this "ishtiak" it will be without "" like this ishtiak but in the text file it will add "" before & after my name.
so the question is: 1.how to add space between name & "ishtiak"? like this = name "ishtiak". 2.My textbox text will be ishtiak,but it will be written like this "ishtiak" [Code]
We have some information that we need to write (about 18KB) to a .txt file stored in one of our network drives. The file is re-written about once every 15 minutes but is read practically at least every second. We are currently using StreamWriter to write file.The file server is in remote location and the round trip ping varies from <1ms to 15ms.
The problem is, sometimes it takes as long as 6 seconds to write the contents to the file, which is definitely way too long even after we take consideration of the network speed. therefore, I am just wondering if there is any efficient way to write the file using VB.Net to improve the performance? Java has a very good tool named BufferedOutputStream, which unfortunately is not available in VB.Net (or I just have not found it).
Application log file have been created to monitor the process and following code has been used to write the log information into text file. For the first time there is no error encountered when the application runs for hours, may be 3 hours i am getting following error "An unhandled exception of type 'System.StackOverflowException' occurred in mscorlib.dll" [code]...
I want to write some stats to a text file every time a person loads a page. But every once in awhile I am getting at 'Could Not Open File, Already in use' type of error. I can not 100% replicate this error it is very erratic. My code is
Public Sub WriteStats(ByVal ad_id As Integer) Dim ad_date As String = Now.Year & Now.Month Dim FILENAME As String = Server.MapPath("text/BoxedAds.txt")
[Code]....
how can I lock and unlock the file so I stop getting the erratic errors?
Im working on an assignment for school and i have to write my schedule to a file using input boxes, also i have to use a structured array on the assignment. Both of these i have working fine.I just have one problem, my formatting such like when i write to the file it doesnt look all nice and straight and when i read from the file its uneven also. I know its because the classnames/teachernames are different lengths but i was wondering if anyone could explain to me how to format it to make it look nicer in the text file, and when its displayed on the form in the label
