View 8 RepliesI'm not sure if this would be this right place to post this, or even if I should go about trying to do it through my program itself or through the computer's settings on the final EXE file, but anyways, here goes.
I have a synchronization program that syncs my flashdrive to my home computer and (hopefully) my flashdrive to my personal folder on the school computers. What I think would be easiest, though, would be if the program was located on the flashdrive, and would simply "autorun" when I plug it in, instead of having 2 separate instances of the sync program running at school and at home.
Would it be easier (or possible) to code for that from within the program, or with the EXE file's settings?
A Problem in accessing a device from VB Windows cannot load the device driver for this hardware because there is a duplicate device already running in the system.

So one is detected the Other is not. It also give a error called designed dragnonacally something...
View 2 Replieshow to use a webcam to take a photo on a Windows Forms application,Now what I need, is to identify which device I'm using to take the photo, in case I ever happen to have two or more similar devices connected to the machine.Currently our setup involves an Asus EEE PC deployed at our location. The machine has an in-built webcam which we are using in the application as described above.Somewhere within this code below, the default device is being identified and selected for taking the pictures we need.
Imports System.Runtime.InteropServices
Public Class Form1
Const WM_CAP As Short = &H400S
[code]....
Now what I need is to find the code that does this identification, and then hardcode the device identity into that code so that if I ever attach another (USB) webcam to the machine in future, it does not inadvertently take a photo from the wrong webcam.

I'm playing with a simple string replacement editor for editing VB.Net functions outside of VB. Is there a way to apply VB.Net code formatting to a string?
For example. The txtboxCodeEntry looks like this:
If strVar="dummy" then 1 else 0 Endif
I would like it to "autoformat" to:
If strVar = "dummy" Then
1
Else
0
End If
The formatting would match whatever formatting VB.Net does when you're editing code in the Visual Studio IDE.

View 2 RepliesDoes anyone know of a way to contain a nonbreaking space in an html tag to allow me to remove it based on conditions tested during runtime in the code behind?
Basically why I need this: if a condition is satisfied I will have 4 buttons, but if it's not only three. I can remove the button but then I have 4 in-between 2 of the buttons instead of just 2 .
Something like the <del> tag would work if it didn't strike through the text.
Basically I have something like this(propery values not included for simplicity):
<td><button />  <button />  <button />  <button /></td>
I can't have the function in the actual button tag because then it will render the   instead of the button text.

I am writing a program in VB 2008 and need to search for SD Card Slots and monitor them. When a card is inserted I want to check for a files and folders and make a button active to upload the data. I take it this needs to be working in the background as I want to be able to perform other functions while monitoring fo the drives.How would I do this and can you check if a removeable drive is SD/MMC, CF, MS, etc?
View 3 RepliesI'm quite new to programming and I am working on a project. The aim is to automatically run a backup process once a removable drive is inserted.So far I've been using this piece of code[code]....
This obviously only runs once unless I use a loop or timer, however both of those will cause the backup process to loop as well.
I configured access control list for the local drives using System.Security.AccessControl
I need to configure it for removable drive .
I want to write a program that will log all the files that has been copied to removable device. I tried to work with FileSystemWatcher but I didn't get the result.
View 3 RepliesI have some VB .NET software that interfaces to a load of old (but sound) COM objects. The VB provides a GUI for the COM objects, part of which consists of setting various options on the COM objects - several of which relate to string formatting.I have a simple pair of VB .NET functions that convert basic %f, %d, %g formats to/from .NET equivalents using a large select case covering specific common strings, but they don't cover all formats.[code]Before I start diving in and making it more versatile with some parsing, does anyone know of a class (eg VB or C# .NET) that provides a decent ready-made implementation? Or perhaps some regexp wizadry could be used?

View 1 RepliesFirst off a short background of the project I am working on- I am developing a program that will be run off removable media (i.e. USB Flash drive). This will be a �virtual desktop� which you will be able to take with you and have the same �desktop� on any system. As we know drive letters can change with each host system the drive is plugged into, I need to be able to determine the path for the flash drive and access a specific folder ( i.e. My Documents)
I have an picture box(representing the icon) placed on my form (form1) and when I click the icon I want to be able to open and view the a specific folder from the portable drive. I need a click event that will determine a dynamic drive letter for a directory on the removable drive and then open that directory in an explorer window.

While I understand there are properties of MailItem that would allow one to programmatically create a formatted email, I would prefer the ability to copy the body of an email that is already formatted to my liking (bolding, italicizing, embedded pictures/tables, set margins, etc.) copy and paste it to a newly composed email such that this formatting is preserved.
