VS 2010 Adding Text To Process?
Sep 22, 2011
im trying to start a process within vb.net as an administrator. I have succesfully impersonated an administrator from within my application, however when I try to process.start to access a UNC path it says login username or password invalid. This is not true because im running as the user who has permissions to access that unc path.
I was able to work around this, by using shell() instead of process.start(). However, with Shell() you can not specify a username and password, so I have to use the runas command. However, shell calls for runas, but runas requires you to enter a password in order to proceed to call the program your requesting runas to run. How can I programmatically enter the password into the runas.exe process as if I entered it manually.
If there is a way to implement this using process.start() instead of shell() please let me know.
This is what I have so far.

Username is named as Email2 and Password is named as Pass2 and the button is addaccount2. The forms are named Form 1 Form 2 and Form 3. I have a listview in form2 that has columns with names and im trying to get it to when you fill in the info on Form3 the username and pass and click the Add account button it will put it in the listview box but I would like it to be so username would be under the username column and password to be under password column under Form2 in the listview.

I am working on a small VB application that listens for commands sent from an Android app.
One of the functions is to extract an archive. I am familiar with how to listen for the unrar process to finish, so I can display a progressdialog on the phone while the extraction is happening, and clear it as soon as it's done.
BUT ... if there is an error/alert from WinRAR, WaitForExit() never gets called because WinRAR is still sitting there open until I click "OK" on the MsgBox.
For Example ... if you try to extract a file that is not actually an archive... an alert will pop up saying "No Archives Found", and basically everything is halted on the VB app and the Android app, and the Android app just sits on a progressdialog saying "extracting..." until you manually hit "OK" on the computer.
As you can imagine, this is a problem if the whole point of your app is to NOT have to go over to the computer.
So... I am wondering if there is something similar to WaitForExit() that will wait for an error and allow me to close out the alert and let the process end.
Here's my Sub for the UnRar command:
Private Sub UnRar(ByVal WorkingDirectory As String, ByVal filepath As String)
Dim objRegKey As RegistryKey
objRegKey = Registry.ClassesRoot.OpenSubKey("WinRARShellOpenCommand")

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.

I have a form that I will be using to copy directories of photos from memory cards to locations on a computer. I would like to add a progress bar to the application to show the progress of the copying in real time. This is the code that I use to copy the directory in the first place
Dim SourceDir As String = SourceTextBox.Text
Dim DestinationDir As String = DestinationTextbox.Text
If System.IO.Directory.Exists(DestinationDir) Then
My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir,)
Else
My.Computer.FileSystem.CreateDirectory(Destination Dir)
My.Computer.FileSystem.CopyDirectory(SourceDir, DestinationDir)

I'm adding controls to a TableLayoutPanel in the form myTableLayoutPanel.Controls.Add(someControl, 5, 5), inserting the control in column 5, row 5. After that line of code has executed, I expect that the ColumnStyles and RowStyles properties of myTableLayoutPanel will contain ColumStyles for columns 0 through 5, and RowStyles for rows 0 through 5. This is not the case. where and when RowStyles and ColumnStyles are added to these properties and the best way to deal with adding styles when inserting new Controls?

I'm reading a file and then closing it with the following code, but my problem is later when I start a batch process it says the file is still in use. Am I doing something wrong in closing it? The process was working fine prior to my adding this code to read the file.
[code]...
This rexx exec is trying to write to the file that I read from in the prior step before creating a PowerPoint presentation, but fails becuase of the lock.I'm at a loss. I should qualify and say the process actually starts, but fails in the rexxexec after it starts, it isn't failing on the process start the rexx exec issues a message that it can't write to the file becuase it is in use.

I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?

I have written a windows service that is meant to launch a notepad when a specific action happens. The problem i have is that even though the service launches notepad, the actual notepad it self is NOT visible. I know that it has been launced because i can see the process in the task manager. By the way the process is listed as a SYSTEM process rather than a process under my user name (i believe that is because my process is a "LocalSystem" one).

I have string which is:
document1.txtdocument2.txtdocument3.txt
What I would like to do is split it so it shows in a listbox as
document1.txt
document2.txt
document3.txt
I have come up with a solution which may work. Its preety over complicated too me but this is the only way I could think of?
What I need help on is a code so that after every ".txt" it will place a "/" so the string will look like this:
document1.txt/document2.txt/document3.txt/
Then I would use this code to split the string:
Dim I3() As String
I3 = I.Split("/")
For g = 0 To I3.Length - 1
ListBox1.Items.Add(I3(g))
Next

I'm trying to use VB.NET to process a very large plain text file (2 GB). It is a database and has a field delimiter of SOH and a record delimiter of STX.
I want to separate the fields and records of the file.
I would normally read each line of a text file and then use the split function to separate out the fields. I can't use this approach as there isn't always a delimiter on every line.
Is there any way to read a file until STX is found (rather than one line at a time)?

I have a "Start" button and a label. The label.text during form load contains "Ready...". Now what I want, after I click the "Start" button, the button will become grey and the label.text contains "Processing...". I managed to make the button become grey, but I couldn't change the label.text from "Ready..." to "Processing..." and back to "Ready..." after completion of the task.
Here is the code:
Public Class Form1
Dim i As Integer
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
[Code] .....
*In actual, the do until loop contains more than just 2 lines.
What happened when I click the "Start" button were, it became grey, it filled up the texbox.text with number from 0 to 1000 and after it finished processing then the label.text change to "Processing..." where it supposed to appear before the loop start.

I have a log file that is open and in use by another program, and I read it's contents with the following:[code]This works for reading the text from the file while it is still in use by the other program, however, immediately after this I need to truncate the text file (without deleting it) so that it is blank again. But the file will still be in use by the other program.[code]But I get the "in use by another application" exception. I've tried looking in StackOverflow and googling but I can't seem to find an answer, and I can't find a way to do this with filestreams either, or I would try to use Dim fs As New FileStream(FullPath, FileMode.Open, FileAccess.Write, FileShare.ReadWrite)

I am trying to create a program that will refresh a *.log file within the program itself (in a RichTextBox), but while the actual application that is writing to that *.log file is open and is utilizing that file as well.
I have tried multiple things with StreamReader, but I can't seem to get anywhere...
Simply, I want to be able to read a *.log file in my Visual Basic 2010 program, but while the actual application that is writing to it is running itself.
How can I do this, as I keep getting the error that another process is utilizing the *.log/text document?

I want the program I am making to show the cursors position on the process it is attached to. Sorry if this is a lot to ask for. Can you tell me how to.
1. Make a drop down menu with the list of process.
2. When i click on one of the processes, my program attaches to it.
3. When I move the cursor over the process, my program tells me the co-ordinates of the mouse on the process.
4. When i press F3, Timer3 Starts.
5. Make the mouse move to a co-ordinate on this process.
If it is too much to ask for, can you just tell me how to do 1 of them and hopefully someone else will tell me to do the others.

I'm completely new to .NET and am trying as a first step to write a text processing program. The task is simple: I have a list of 10,000 text files stored in one folder, and I'm trying to read each one, store it as a string variable, then run it through a series of functions, then save the final output to another folder. So far I can only manage to manually input the file path like this (in VB.NET):
[Code]...
I'm wondering, therefore, if there's a way to automate this process. Perhaps for example store all input file path into a text file then read each entry at a time, then save the final output into the save path, again listed in a text file.

I want that label to change to "Done!" when the process does not exist anymore.
