[2008] Display The Process Name When Parse A File?
Mar 16, 2009
I am parsing many files after I click the button.I want to display the process name when I parse a file. So I am going to display it as
Label3.Text = "Parsing File " + FileName
The problem is the screen is freeze if too many files will be parsed. So designing an event to display the file name that is processed is a good idea. But I haven't any experence on it.
Private Sub ExtractButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ExtractButton.Click
Dim saveFilein As String
Dim FileName As String
VB 2008 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click 'Dim Reader As New StreamReader(Application.StartupPath + "/pbucon.log") 'TextBox1.Clear() Dim Reader As New StreamReader("C:/Documents and Settings/Dorinda/Desktop/pbucon/pbucon.log") Dim Line As String = Reader.ReadLine() [Code] .....
I am trying to parse a log file and only display new entries containing the word "say". I have this set on a button click event, but I prefer a timer or something, but the textbox flashes everytime the timer ticks so I am using a button right now..
So i am working on a program that needs to run NSLookup for a Computer name specified by the user. Here is the code I have developed which works:[code]Now because of the dynamic domains that this will be on, it is difficult to nail down which character to start a read at to determine if the Computer name exists. For some reason the reader is not picking up the '***Non-existent' line that is reported from NSLookup. When i run the NSLookup it requires me to run the Function 2x before it displays a result in my lblresults. With that pre-knowledge,
1. How do i make the NSLookup Process more efficient?
2. Is there a better way to Parse the information to specificly pull the lines that have been reported back, specificly the '***Non-existent' line.
Some things with the file are standard, like the "TableName" (Never in quotes) starts the table. Variables always have [" "] around them and then equal something like ["Test"] = 0. However, the variable could have multiple variables within it. split up the file within each {} and then try to parse each ["QuotedString-Key"] = 0?
I have spent the last 20 plus hours trying to parse a incredibly small XML file with Xpath. I understand that it is a ready only, extremely fast way to pull values out of an xml file. Here is the string I am working with. I have a 3rd party function that returns results, based on these xml results i would like to retrieve certain vaules.
I am trying to parse a very large text file for certain strings. The text file is part of a level-making software for an old game I play. The text file basically contains all the information the level designer software needs, but the only important bit is the 'texture information'. Basically what I'm trying to create is a little program that parses the text files and shows the user a list of every texture in that text file. The problem is, the strings denoting textures are not really easy to find, and I can't think of any sensible and fast way to get them...
I have a gridview which returns a number of columns, sorted by date.If possible I would like to display each distinct date only once. So, for example, if there were 5 records for 18/06/2009 and 3 records for 19/06/2009, they would be displayed as follows;
'Date Name '18/06/2009 John '<no date here> Mary '<no date here> Susan[code]......
I am new to Visual Basic and I am having some problems with a programming challenge. The user is told to enter their city, state, and zip into a textbox seperated a certain way (Ex. City, State. Zip). The program is supposed to display the City, State, and Zip in three seperate label boxes broken up. So far the code that I wrote for the button click event displays the count up to where a comma is found (City). Im not sure how I would display the word instead of just the count. Also, finding the state and zip after the City is found. I know I have to use the IndexOf method as well as the Substring method.
Here is what I have so far: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click Dim strCity, strState, strZip As String Dim strInput As String = txtInputData.Text Dim intCount As Integer 'Obtain the count for city intCount = strInput.Length strCity = strInput.IndexOf(",") lblCity.Text = strCity End Sub
I have a very weird problem. In the constructor of my class, I create a new directory if it doesn't exist. After that the method Debug is being called from another class. But then it gives a error that the file is being used.When the directory already exists, I don't get this error when calling the method Debug.
This the
Public Class Backup Private oWrite As System.IO.StreamWriter
[code]....
edit: It get the same error if the directory exists but the files don't. So I guess I am forgetting a important step during those if statements.
below is my procedure (the important parts).Simply, it creates a file with the client's ID number and today's date number if no file exists (and in this case, we are creating a new file).Then, it loops through all files in the folder (in this case there will only be the one we just created), and opens the files and imports the data (since we just created the file, it will be empty). In other scenarios, there could be 3 files out there in the folder with 10 records each. This procedure would open these files and import their data.The problem I am running into is when there is NO files in the folder, so it creates one. Then when it gets down to reading the files, it finds the file just added, but throws an IOException: "The process cannot access the file "C:20200_8.bocx because it is being used by another process.It happens on the line USING SR AS NEW STREAMREADER(F.FULLNAME).So I'm sure the problem is that the new file that is being created is still open. How would I go about closing it?Right now the remedy is to let the program crash, then restart and it will load just fine.

When I load my solution and compile it after first starting the IDE, everything works as expected. After changing source and recompiling, I get the following compile error:
Error 11 Unable to copy file "objDebugCAMDRS.Library.dll" to "binCAMDRS.Library.dll". The process cannot access the file 'binCAMDRS.Library.dll' because it is being used by another process. CAMDRS.Library.
After closing Visual Studio 2005 and reopening the solution I can compile again successfully. This is an old solution that has been fine for a long time. I just recently changed computers and reinstalled everything.I am running win XP Pro sp2, Visual Studio 2005 sp1.
I have tried a few things like converting HTML to XML and then using an XML navigator to get input elements but I get lost whenever I start this process.What I am trying to do is to navigate to a website which will be loaded using textbox1.text.Then download the html and parse out the input elements like . username, password, etc and place the element by type (id or name) into the richtextbox with the attribute beside the name.[code]Any clues or how to properly execute an HTML to XML conveter, reader, parser?
My program writes to a .txt file (and this is the ONLY program that writes to it) in a thread (with lowest priority), but every now and then it gets an error "The process cannot access the file because another process has locked a portion of the file" when it executes this code: swLog.WriteLine(sPacket).Other program reads from the file, not write to it, why do I get this error, and how can I get around it, or what shall I do when I get this error since I can't write to the file ?
I've got an import program that reads csv files and imports the data to a sql server database. After the import I call a send email procedure which takes some arguments including the two files and adds them as attachments to a mail message, then sends the email:
I'm trying to open any file using Process.Start, but every time I try to open a file that isn't an executable the program crashes... This is the code I'm currently using:
vb.net Private Sub ListView1_MouseDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListView1.MouseDoubleClick For Each lvi As ListViewItem In ListView1.SelectedItems Process.Start(path & "" & lvi.Text) Next End Sub
Path is a string that contains the selected folder path, and lvi is the text of the list view item (each item contains the icon and name of each file). It is working fine for .exe files, I was just wondering if it's JUST for .exe files...
The process cannot access the file 'C:UsersdavidDesktopTest Folderdavid 2.xml' because it is being used by another process.
how do i end the prosess after I create the file? Or am I creating it in the wrong manner.The underlined line is where the error ocures.

i am trying to open an external executable file during runtime using a process component and the process.start() method. I've been testing out my code with various executable files on my C: drive....some work and some do not work. I've been able to successfully open Adobe Acrobat, Microsoft Excel, and Notepad; however, when I try opening various other executables the following exception gets thrown:
A first chance exception of type 'System.ComponentModel.Win32Exception' occurred in System.dll
I cannot figure out why some programs open just fine while others cause the above exception to be thrown.
I try to open a text file and write in some text, when i run the program it says the following error:The process cannot access the file 'D:VB projectsCategory_Characteristics.txt' because it is being used by another process.
THe code is as follows and the error hits in line :
Dim objWriter As New System.IO.StreamWriter(FILE_NAME) ----------------------------------------- Dim FILE_NAME As String = "D:VB projectsCategory_Characteristics.txt"
How can i access a file through FileStream which is being used by a window service. Actually i am trying to access a file which is also being used by our window service. I need to read data from this file. I am using below code but also getting following error:
Code: Dim fs1 As IO.FileStream = New IO.FileStream(psPath, IO.FileMode.Open, IO.FileAccess.Read, IO.FileShare.Read) Dim sr As IO.StreamReader = New IO.StreamReader(fs1) sData = sr.ReadToEnd
Error: The process cannot access the file 'FILENAME' because it is being used by another process.
I tried changing FileShare.Read parameter to FileShare.None but it didn't work out. I also read below post which says that it is not possible but i think there is a way to read it like if you open a file through Firefox but still window service is accessing it.
I am working with saving and deleting images. What i really want to do is check and see if an image exists in the destination folder and if it does automatically overwrite it. i couldnt figure that out so i figured i would look to see if the file was there if it is Delete it then write the new file..The issue is i keep getting this error.The process cannot access the file "FileName" because it is being used by another process. [code]
Im simply trying to load a file on my network. The file is a database file for access.. This code opens the file on my computer. However on the four computers tested 2 of them throw an error stating that the user canceled the operation. However the user didn't do anything. The error is thrown automatically. The other two are working perfectly fine.
# TAG NAME = is saved to a file using the code below but when I load that same file back into a RichTextbox Control using additional code below, I get inconsistent results as I try to parse the text. Has anyone else had this problem?'Save the contents of the RichTextBox into the file.richTextBox.SaveFile(saveFile1.FileName, RichTextBoxStreamType.RichText);'Retrieve contents of File into RichTextBox control Dim logData As String logData = System.IO.File.ReadAllText(path + "\" + filenname);
Trying to create a button that when clicked will check to see if a certain process image is running and if that process is running give the process focus. If the process is not running then start the application.
The process cannot access the file 'C:UsersJoshuaDocumentsTest1.txt' because it is being used by another process.Now the Problem. When i step through my code, it will do as intended, e.g. clear all contents of test1.txt. when i run it at run time it throws this error. The reason for it throwing an error is the text file is reading string, int, string, and the txt file has a string including in the int part, so i'm making it so you can empty a corrupt file.
