Complete Noob With A Text File?
Apr 1, 2010
I'm a complete programming nublet.I got nothing.But I'm trying to start learning. I figured the best idea was to figure out some things I'd like to be able to automate, pick some that sound relatively simple, find code that does it, and start picking it apart. I haven't found what I'm looking for on this one, so I figured I'd ask here.
What I am trying to do, is create an exe (so it can be run remotely with admin priveleges) that will read a file, determine if a couple lines exist, and if not, will write them in the correct spot in the file.
Am I being too ambitious on this? Can it be done? Can someone help me with how?

I know there's ton of examples on the forum but i could not get it to work the way i want.
Sample CSV :-
Unused,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
And what i wana do is change the Unused to Used so basically once this is done it will look like.
Used,172.22.21.2,SD103001
Unused,172.22.21.3,SD103002
Unused,172.22.21.4,SD103003
One thing to mention is i dont want to loop through the whole file and change all the Unused to Used. So basically software fires up opens the file and looks for Unused and changes it to Used and does the rest of the function and shuts down. Next time the software is fired up it goes through and does the same thing.

Total noobie when it comes to VB, but I'm jumping in. I have about 15 years with Business Basic and see many similar things between VB and BBx so hopefully the learning curve will not be to steep.
Anyway the project I wish to complete is: Use portable computers running Windows CE 5.0 to scan bar coded labels to capture data collected during a physical inventory. The labels have 2 fields - bin location and item. My form will have a textbox for 3 items - bin location, item and quantity. Also, the form will have 2 radio buttons to accept or reject entry. I plan on writing the records to a simple text file to import in to the current application I am running.
I downloaded Microsoft Visual Basic Express 2008 and have done a little prodding around so far. I know the Express version does not support mobile device application development so that needs to be upgraded. My question is, can someone recommend a good book that would cover the areas I need to be concerned with?
Also, any good online resources?

I have a text file that I am reading from which is a list of first and last names. They are in order but they are on different lines of the text file. I am trying to read them into an array and put the first and last names together on separate lines.

I've got a basic email application set up, and I'd like the "To" field (TextBox1) to be an autocomplete textbox.I'd also like the user to be able to edit what their contacts are, and so be able to add named to the autocomplete suggestions.I can get TextBox1's autocomplete suggestion to come from TextBox2's current Text - however this means I can only have one name as a suggested contact.Ideally, something like a list box would be ideal, so the user can add and remove names, and this list would then provide the source for the autocomplete.

When setting up the Ajax Control Toolkit's AutoComplete control, it creates an utoComplete.asmx and a AutoComplete.vb file. The AutoComplete.vb file automatically ends up in the App_Code folder. I was hoping to move all of these styled-classes into a separate namespace, but the compiler simply does not dig it. Is this possible, or must it be within the presentation layer to access the "Web" related namespaces?

In a windows forms application I am attempting to read a file from a share into a filestream.I then start impersonating and write the stream to another share that only my impersonation account has access to.This works fine for small files. But if I attempt this on a 90 meg file I recieve a "Insufficient system resources exist to complete the requested service" error on the following line:
System.IO.File.WriteAllBytes(myLocation,MyByteArray)
Full Example:
Dim ImageData As Byte() = Nothing

Hi, i'm trying to use the treeview to display the text of a rtf (rich text file) file when an specific node if clicked.HomeOMGWOOTFor example, if i pick OMG, i want the text of lol.rtf to be displayed on a richtextbox. But somehow i just can't manage to get it... I know to import the text of a .txt file to a textbox, but using the treeview makes it more complicated.This is the code im using right now:
Private Sub TreeView1_NodeMouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.TreeNodeMouseClickEventArgs) Handles TreeView1.NodeMouseClick
Select Case e.Node.Index
Case 0
[code]....
Another thing is, that i can't import the *.rtf text into a richtextbox and i don't know why.

So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
