Stuff like this makes me hate computers! Anyways, I'm again struggling with something relatively simple - or so i thought.I have a sub:
[Code]...
Then, I have a sub that runs every minute, calling yet another sub, which calls this one. Before you say whoa! that's too many, I'll say that each of these subs has a different purpose.The whole problem is that the WriteToFile sub writes only once to a file! Instead of continously writing to the file every minute, it stops at the first line.
Lets assume I have a DataSet that contains the following info (columns seperated with | character):
1 | Logan | Young 2 | John | Doe 3 | Jane | Doe 4 | Joe | Soap
If I now write this info to a text file, but later want to append 5 | Susan | Sarandonto the end of the text file, I obviously want to check that the text file doesn't already contain the data that I want to append to it. I'm having a little difficulty figuring out how to perform this check...I know you'd have to loop through every row in the DataSet's table and compare it to every line in the text file. That part's easy.
We are trying to Open a text file and if our needed information isn't in there, we need to write it, otherwise we need to append to the existing text. We had it working in VB6 (below) and i havent the slightest clue
CommonDialog1.Filter = "Text Files (*.txt)|*.txt" CommonDialog1.FileName = frmSplash.fp & "\job_info\" & nam Open (CommonDialog1.FileName) For Append As #1
I have a VB 2008 program which shows the user's results in a ListView, and permanently stores them in a Notepad (.txt) file. The program works fine when I run it using Debug. The permanent records show up on a .txt file in the "bin". However, I want to publish the program as an executable file. I have tried this using my normal method of selecting "Publish" from the "Build" menu, and my program runs fine but there is no .txt file to be found.
I have a piece of software that can be used either on an admin account or a standard user account of a completely stand-alone, Windows XP machine.
I have also set up some log files that the system uses when it either performs an admin function or if an error occurs. the location of these files is a C: location - not (from what I can see) associated with the admin account in any way.
When running the software from the admin machine, the log file is appending fine. When running the software from the standard user machine, the log file causes an error, suggesting that "Access to the path 'C:HNP MTWP Log FilesAdministrative ToolsAdmin.log' is denied.
This error occurs when first setting up the FileStream. Here is my code.
Imports System.IO Public Class Log Private Const cnDirectory as String = "C:HNP MTWP Log FilesAdministrative Tools"
Is it possible to append text to a text file located on a webserver from a winform? If so, can you please point me in the right direction. I've searched this forum but can only find documentation on appending a local text file.
I have a several text files that get updated each month - when they are updated certain lines are missing that I always want adding back to the files - the text I want adding back needs to go into a specific part of the text file(its always the same text that needs adding and same location)
With the intention of creating a program to interface with a serial port device, I recently started learning vb.net. To keep the structure neat the vb code has been split into two places; the first is the code behind for initialising, clicking buttons etc., whilst the second is for managing the comm port. Respectively, these are named 'MainWindow.xaml.vb' and 'ComPortManager.vb'.
In 'comPortManager.vb': Dim RXArray(2047) As Char ' Array to hold received characters Dim RXCnt As Integer ' Received character count
For some odd reason, when I download text files, the HTML of the web page is being appended to the text! All other file types work fine!Here's the code that's doing the download:
Public Sub DownloadBlob(ByVal Blob As Byte(), ByVal FileName As String, ByVal Response As HttpResponse) Response.AddHeader("content-disposition", String.Format("attachment;filename={0}", FileName.Replace(" ", "_"))) Response.ContentType = String.Format("application/{0}", Path.GetExtension(FileName).Substring(1)) Response.BinaryWrite(Blob) End Sub
This append feature does not seem to work. I've looked in many places to no avail. The other examples below for writing and reading seem to be going fine.
Private Sub ApFile(ByVal textFilePath As String) Dim objWriter As System.IO.StreamWriter = file.appendtext("textTBD") objWriter.WriteLine("textTBD")
The user starts out by pasting text into a textbox:
1.Phototypesetting was superior to automated typesetting because it was
(A)Easier (B)Faster (C)More flexible *(D)All of the above
What I want to do is to tag the sentence and format it as follows: MC Phototypesetting was superior to automated typesetting because it was (A)Easier incorrect (B)Faster incorrect (C)More flexible incorrect (D)All of the above correct Using the following code I can easily replace the number (1) with MC:
But for the life of me I cannot figure out how to tag each choice with correct or incorrect. The correct tag will go to the end of the choice which starts with * eg *(D) All of the above correct, while incorrect should go at the end of all other choices.
I want to make a timer that reads a new line every second from a text file until the last line and then gives a message that there are no more lines. But when i do this he only reads the first line every second.[code]...
I'm trying to find a way to change the color of one word when appending text to a Rich text box. So if I append the sentence "This is a sentence with a specific word in one color" The entire thing will be in black except for the word "specific" it will be in red or any color I choose. The same thing will happen if the next line appended is "Please be specific in your request". All back except for the word "specific". I don't want the text added then someone has to click a button to change the color. It should happen as it's appended.
I would like to know how it's possible to append text between data.
For example:
I have a RTB with "ABC" on the first line and "DEF" on the third line. My question is how would I insert text data into the second line, without changing any existing data.
I am trying to save the contents of a richtextbox to a text file. I know that they .SaveFile method automatically overwrites the existing file so I have a routine that will load the contents of the file into a temporary rich textbox control then append the new information to that and then save from the temp richtextbox. My application works as I want it to on my workstation but I cannot get it to work correctly on the notebook computer it will be running on from now on. It only works when I put in a breakpoint and I am not sure why?
[Code]...
If I put breakpoints on any of the lines rtb.Select, rtb.Copy, rtb.Paste then it works. I even tried putting a Thread.sleep before saving, thinking that more was needed to do the copy/paste but that didnt work either.
My user can export a ".doc" file but when VB.NET writes to this file it uses "" and "," characters at the end of each sentence. I was wondering if there was a way of actually appending the exported file to remove these characters?
I have a resource file that is a dictionary.txt file, which is basically a list of 100,000 odd records. I want the user to be able to add new words to the resource (which will be embedded in the final build).I can find ways of adding records to files e.g.[code]But how to i write new records to an embedded resource file?
I am reading text from a file (*.TXT) 1 line at a time using streamreader. As I read that input, I am looking for specific starting and ending character strings ("<" and ">") . When I find those strings, I would like to select the characters between those string and have it set to BOLD and BLUE before appending that input line to the contents of a richtextbox.The only way I have found to do this is to first append the input line to the richtextbox then use the richtextbox.selection (color and font) methods to change the text.
I am creating an xml file if it does not exist, but am having trouble with appending to the file if it does exist. I am using the reference System.Xml Here is my code:
Code: Public Function App_Path() As String Return System.AppDomain.CurrentDomain.BaseDirectory()
I need to create a timer that sets the time from an existing text file. The time format in the text file is 00:00:00 (hours,minutes, seconds). An excerpt from one of my text files looks like ClockSet = "00:49:05"
Also, if possible, when the timer reaches 2 minutes I would like the backcolor to flash between red and green.
How would I use the BinaryWriter to append binary data to a file that is very large? Say a file that is 3GB in size. The BinaryWriter's write method will only accept an integer for the index value. I've attached a screen shot of what I'm talking about. If I were to enter a value that exceeds the size of an integer on my 32bit Windows XP system, which I believe is 2147483647 it will reject it right?
I got a log file (Log.txt) a timer and a RichTextBox1.Text The timer is opening the log file again and again every milisecond here the code:
Code:
Okay that keeps the track of my log file inside my richtextbox , but there is a big problem there. My richtextbox slows down hard if the log file gets too big.. Sometimes it kicks me out of the program and in taskbar it says Program Not Responding..
I wanted to know if there is a method to read a bigger Log file with out having such issues. (It mostly happens when log file goes over 13000 characters)
I need to Change text of label One by one with One timer For Example! "S" 'step1 "Sh" 'step2 "Sha" 'step3 "Shar" 'step4"Shari" 'step5"Shariq" 'step6"ShariqD" 'step7"ShariqDO" 'step8"ShariqDON" 'step9
