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.
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
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 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.
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.
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 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 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
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 have the following code which appends a text base file knowen as a .pgp file; all works fine except that everytime i launch this app i append the text in one continual line i need the text to appned to a new line eveytime it is used.Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
I am trying to use and display calculations from various text fields, however it is appending the values. I think it has to do with it being a String Variable and not a Value.. here is the code
Private Sub btnTransact_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnTransact.Click If rb1Deduct.Checked = True Then txtp1Amt.Text = (txtp1Amt.Text - txtTransact.Text)
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")
vb program to append two pdf files together into one? I have invoices that are created as pdf files and I need to append a special announcement also a pdf to the end of it so I can upload one file to the internet for customers to download and view.

One of my projects i'm working on takes data from a server and places the results into a DGV, problem is the data is some 10 pages long in blocks of 50, i have tried to do DataGridView1.DataSource += query.tolist but i get an error.I have also tried creating a string and trying to add the query results to it but again i get an error. The code i have is like this:-
[Code]...
I haven't yet tried, but would the data append to the dgv if i just called this again using query and removing the queryTotal variable? seem to think they behave like that from past tests?

Im making my own process manager. but if you update it every second to keep it in real time it makes this horrible shudder (items being removed and updating) losing your selected item in the process.[code]how would i change that to only add the new items rather then restarting?
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 create a function that will make a treeView out of link buttons. Then I want to tie all the link buttons to one click event. So each time the user does somethingI will append the users name to the current linkbuttons if the user clicks one of the link buttons a click event is raised and I can extract the text of that button.
Here is an example: Nick ...user does something...now the link string says Nick > Jeff ...user does something...now the link string says Nick > Jeff > Charlie and so on.
Now I want to give the user the ability to click one of these link buttons (there are 3 in this example). If the user clicks one of the buttons a click event is raised and I can extract the name out of the text of teh link button.
