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"
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.
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.
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 do I search all the user accounts in a domain in .NET? Not the computer names in the domain, but the user accounts, that's what you are using to log on Windows.
I am a programmer for 6 years with VB6, now I am using VB 10 Express and working with Active Directory for the first time. I have been able to make a lot of things work with AD.I have been trying time and again to make this work. I have been googling and trying samples and keep running into one error after another, the latest is a [code] "There is no such object on the server."[code] My objective for this is to move the user account from the office OU to the Disabled OU. I have been fighting this for so long that I am going crosseyed.[code]
Currently, i have a simple application that manages the user account on a machine. The functionality includes the adding, deleting and modifying of user account. For deleting a user account, the username has to be entered into a text box. But i want a combo box to be created and named of the user account that are already created on the machine
Would it be possible to make a webbrowser link to the cookies and such of any windows user account no matter which windows user account you were on. So the user would use a drop down list or something then press a button and be able to switch to another user accounts internet explorer favourites, cookies, and flash cookies, rather than having to log out and then log into another user account?
I have never worked with datagridview before. I need to know how to use it so i can use it in my (calculator) program. I would like to know how to make columns, rows, linking the cells in the table/grid to textboxes so values entered into the textboxes (on the calculator) after pressing save goes straight to the table.
I am working on a VB.net form, I am trying to connect to Active Directory, with a VB form have the user be able to search for a username and then return if the account is locked or unlock, if the account is locked I want the option to unlock the account based on the credentials of the user that is doing the search.
Is there anyway to return a list of all user accounts on a PC running windows vista business edition using VB2008?I am trying to integrate a type of security in my application using what it already implemented in windows.
create admin form to register, Remove, Edit user accounts in the system connected to Microsoft SQL Server R2 2008 or access database ? any toturial videos or instructuions step by step ?
Well, in my previous thread i needed help deleting arrays, for the codes i use its here[url]...
[code]...
Well, i want to save my array to a file that will be encrypted and then i could read it, example when i have my arrays in the application and i save it, i close my application and then i open it again i would like to load all the arrays and all the items in the "DomainUpDown" with a button, which will be read from the file, but i don't want the file to be seen from the users for secure reasons, i would like it to be encrypted.
What i had in mind was saving it as ini file, encrypting the file to another extension, and encrypt it to binary, but to do that i would use the special folder in the AppData, is there a better way for me to save the arrays and encrypt it and be able to read it again and load it in my application ?
I'm trying to make a simple program that stores my accounts in a .txt file. Each account has 3 properties, account, password, and source. I know there are alot of better ways to do this, but I'd really rather use a text file because I'm working with PhP also.
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'm currently working on a program to store files and information. I'm wanting the program to be able to have multi-user logins i.e. there are numerous combinations of usernames and Passwords. I've created a program that will create new accounts and save them in a .bin file (in the form Username Password). However, now I need to use the user accounts to grant access to a form.
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.
