Keydown Space/Enter - Use The Space Or Enter Key To Change The Image In It?
Sep 8, 2011I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown
Select Case e.KeyCode
Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)

Use Memory As Storage Instead Of HDD?
Mar 31, 2012I have been trying to do this for about a month now (hard to get answer quick because of school), but i need to decrypt a file into memory. I know you have to "write all bytes to memory" but i have two problems with that, 1. I have never touched on that itself and don't know how to write the bytes of an executable to memory, 2. I still wouldn't know how to decrypt it in memory. Right now my code is:
ElseIf entype = "rc4" Then
If File.Exists(thepath & exerandname) Then
Kill(thepath & exerandname)
[code]....
it checks if the file exist then deletes it, then it opens the file and decrypts (_4reversecr.enc) the file(Cutter(1)) with the key (key)?
.net - VB In Program Information Storage?
Oct 7, 2011I'm making an installer that needs to have information stored inside the exe itself.I cannot use my.settings because it is stored outside the application and if it is changed and the exe is moved to another computer it will reset to default.
And I cannot use resources since I cannot add/edit resources after the application is build.
Is there any way I can store and change info even if the application is moved to another location?

Creating Isolated Storage?
Jan 12, 2011I was reading an article about isolated storage and thought of doing the following.Encrypt files.Add them to Zip.Unzip the file,decrypt the content and copy all the files and folders into an isolated storage and then load a specific file into a web browser and launch lets say an HTML page I got stuck on the Isolated Storage thingy
here is a part of my code
'So far i unzipped the content of the Zip file
'Setup file streams to handle input and output.
fsInput = New System.IO.FileStream(strInputFile, FileMode.Open, _
[code]....

.net - Parallel.ForEach Local Storage?
Aug 3, 2010I recently changed a For Each loop to a Parallel.ForEach loop. I'm concerned about an object being declared outside the loop but assigned while iterating in the loop. Here is the simplified code.
Dim results As ModelResults
Dim noResultsModel As New List(Of ModelResults)
Dim lock As New Object
Parallel.ForEach(_modelEngines,
Sub(model)
[Code]...
Is there a potential race condition with the results object? Would anything be different if I moved the declaration of results into the for loop?
Accessing MP3 Player / USB Storage Device?

View 1 RepliesAdd A Document Storage Module To AR Software
Jul 7, 2009I am attempting to add a document storage module to our AR software. I will be prompting the user to attach a doc/image to thier account. I will then put a copy of this file into our folder so that we can reference it without having to rely on them keeping the file in its original place. This system is not using a database but instead its using multiple flat files.
I am looking for guidance on how to handle these files once they have attached them to our system. How should I store these attached files? I was thinking I could copy the file over to a sub directory then renaming it to a auto-generated number so that we do not have duplicates. The bad thing about this, is the contents of the folder can get rather large.

View 5 RepliesDeployment :: .NET App Updates And Isolated Storage?
Jul 2, 2009The Windows Application we are coding uses an XML to store connection settings etc. The application also needs to update automatically online. The problem is that the config file is replaced when the application is updated and the user has to set up the application again (definetly not ideal!).I placed the XML file into isolated storage, no problems doing that. But still when the application is updated the isolated files get replaced/removed and the user has to reset their settings..

View 5 RepliesHow To Create Dynamic Storage Of Data
Jan 26, 2012I'm a junior VB programmer and looking for some advice on this subject. I'm trying to create a chunk of code that will create dynamic storage for variables for use later by dynamic custom controls.
For example:
An INI file might have an entry in it that looks something this:
....
[var1] <-- this becomes the Storage name
description=My Variable
type=System.Int32 <-- this could be any valid VB type
last_val=456 <-- Other code would save the last value
....
And I want to access the data using a standard "property set" like so after it's created:
var1_reference.value = 55
I've tried using a generic class which works ok as long as I declare the variables at design time from within the design environment. But when I try to create them from the INI file it gets messy.
Here's the simple generic class i've constructed to test this:
Public Class GenericVar(Of T)
'
' Generic Symbol Class for data storage
'
Private VarName As String
Private VarType As Type
[Code] .....
Also, as each object is created (and they could be different types) I store a reference in an array to make it easier to keep track of, but I'm having a hard time getting access to the objects and their properties, and certainly cant seem to assign an event handler to it once its in an arraylist because the design time code doesn't know what "Type" it is in the arraylist of objects.
Isolated Storage For Log File On XP And Windows 7
Sep 10, 2010I'm restricted to .Net 3.5 so I can't use isolatedstorage.getfilenames() as in .NET 4. What I have below isn't working yet. I do get to the messageBox included in the code below but I can't find the file "IST_Log.txt" anywhere on Windows XP where I ran the program. I saw the messagebox appear 3 times meaning AppendLog was being called. What do I need to do to write this file on either XP or Windows 7?
Public Sub appendLog(ByVal message As [String])

Moving A File To A Storage Device?
Aug 1, 2010Is it possible in VB.NET to get the directory of a file copied/moved to a removable storage device?
For example, I have msword document on my desktop and move it to my storage device. A dialog box will appear or anything that will show the directory of the document.
The idea is whenever you move a file into the specific device, it will automatically processed. I will be using this to compress a file automatically when it is moved or copied to the storage device.

View 2 RepliesSending BMP Logo To Printer For Storage
Feb 28, 2009I would like to ask a question about sending a BMP logo to a printer for storage. As I used to send a txt file to the printer, I just read through the file and store the contents of the file in an string. After sending the string to the COM port connecting the printer with "ComPort.Write(msg)", the txt file can be successfully printed. When dealing with the printing image problem, I tried to read the image with a binary reader and store into a binary array. Then I write the binary array to the COM port connecting the printer, with "ComPort.Write(bitArray, 0, bitArray.Length)". I am still quite new for VB.
View 2 RepliesUsername And Password Storage Location
Apr 18, 2011I am writing a program in vb.net that requires a user to log in before he can use the application. The main user is created when the program is installed, similar to how windows works when it is installed.
The main user can add additional users to the program. I already know that I should store the passwords encrypted. My question is, where should I store the usernames and passwords? The registry, Isolated storage or .config file. I don't want any user to be able to modify/delete that file as the other user would obviously not be able to log in. Also, this file should be accessible for any user that logs into the computer.The computer is not guaranteed to be connected to the internet, so it must be stored locally.
Vista (and Windows 7?) Data Storage
Oct 19, 2009I have and application written that works great on XP. It is VB.Net 2008, using .net 3.5. I install and Access database to the program file directory. In Vista, I get an error that is permissions related as even admins don't have default write permissions to the Program Files directory and access creates a .ldb file when in use. To solve this, I have had the users give themselves permission to the folder.
Is that the best solution? If not, where should data be stored in Vista and in Windows 7? Also, I have an update feature of my software that will download updates to the program files folder. Is this out, too?
VS 2005 - FileStream Storage Across Forms
Apr 17, 2009I have a button on form 1. When the button is clicked, form 2 pops up. Form 2 also has a button.
Code for form 1:
Imports System.IO
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim textfile As New FileStream("textfile1.txt", FileMode.Create, FileAccess.ReadWrite)
Dim txtfilewriter As New StreamWriter(textfile)
[Code] .....
Now, as you see, on the form 1 load event, the streamwriter writes "Physics" to the text file. When the button on form 2 is clicked, the streamwriter writes "English" to the same file. As an end result, I expected BOTH "Physics" and "English" to be in the text file but the final result is only "English" in the text file. What do I have to do so that the textfile continuously stores these lines?

Write A Recipe Storage Program For Personal Use?
Oct 10, 2009I am planning to write a recipe storage program for personal use. I know what I want to do, but I am not perfectly clear on the most efficient way to do it. I am using SQL server 2005 and I am comfortable writing stored procedures. This is one of my first vb.net projects and I am still getting comfortable with ADO.net.What I want to do is create a form that can handle an list of ingredients of an unknown number.
The form will also accept a cooking procedure of an unknown number of steps. Each step will be written by the user into Rich Text boxes (vb 6 term?)I am planning to use combo boxes to select ingredients from a list or add new ingredients as needed. I also want to eliminate duplicates in the ingredients table of the sql 2005 db. I am looking for the most efficient method to save all the parts of a recipe to the database. saving a recipe will require dozens of database hits and therefore be unacceptably slow.
.net - Word Automation : Could Not Open Macro Storage
Mar 7, 2012My application (vb.net windows application deployed via ClickOnce) uses Word to open and fill .dot templates to create new Word documents. I reference Microsoft Word 14 Object Library and uses this code :

Dim oDoc As Word.Document = Nothing
Try
[code]....
On the last line I receive "could not open macro storage" error on deployed machines (not on my development machine).I develop with Windows 7 - Office 2010 - VS 2010 (.Net 3.5). My deployment machine is also a Windows 7 with Office 2010 installed.I tried to remove normal.dotm (I found some links advicing it) without success. The .dot template used contains no macro.
