How To Get Unique IDs Of Various Storage Devices (usb Stick, SD Card, External HDD, Etc)
Mar 18, 2012
I am trying to come up with something that will let me obtain a unique ID of some sort for most types of storage devices. These can be USB thumb drives, SD cards, external hard drives, etc.
I have run across this:[code..]
But I can't find anything similar within .NET. Can anyone point me in the right direction?
My end goal is to be able to define specific hardware storage devices, and then have my application auto-detect them when they are plugged in.

I am trying to write a simple standalone windows forms project that basically contains various buttons which run external application setup files. The problem is I want to be able to run it from a USB stick. I have created a folder inside the project with all the files I need to call in it. I am using Process.start but the paths are obviously going to be wrong when the project is running from the stick as the drive letter may be different each time. How do I over come this.

project im working on for my course,the idea is a photo printing machine that loads up 4 images if usb stick is checked and a different 4 if memory card is checked. and then whatever image is selected appears in the big picturebox on the left [URL] i have 2 print size options set as radiobuttons, radiobutton 1 = 6x4, which costs 25cent per photo, radiobutton 2 = 8x10, and is 50cent per photo.i also have a textbox which will display the number of copies to be printed So here's my dilemma, when the print button is selected alongside one of the radiobuttons i want it to display a message saying something like this "you have selected (whatever the amount of copies)of this photo sized 6x4, or 8x10 depending on which radiobutton is selected, and i want it to display the total cost which is the number of copies multiplied by the rate for the print size selected, then an option saying "Do you wish to proceed" Yes or No.
I did something similar to this in class earlier in the year but cant remember it, it was an airline booking program with 3 types of payment cash, visa or mastercard,upon booking a message popped up saying there is a certain percentage discount for using visa or mastercard

Is it possible to capture the raw signal from a WiFi card in the same way you can capture the signal from a sound card? (I already found code for working with a sound card and for drawing spectrograms) I'm wondering because it would make a cool radio-type project. I'd prefer a solution that integerates well with .net (VB or C#).My basic goal is to capture the ambient radio waves and build a primative "telescope" of sorts. Using the built in computer hardware is just the easiest way to accomplish this. If you have any other suggestions about how to accomplish this goal in a different way please post it as an answer also.

I am using VB .Net to access the eBay API and store all completed orders in a database. This database is then fed into a proprietary shipping system, which can not handle an order number larger than 20 characters. eBay returns an order number like so 230407279314-680141236013 which is too long. The order number is always 12 numbers a hyphen and 12 more numbers. What I need to do, is turn this (the result can be alpha numerical) into a shorter, unique order key to store in my database alongside the true orderId (so that this can be referenced by the shipping software instead of the actual order number). The reason for the 20 character limit is the barcode algorithm used. Is there any way to achieve this in VB .Net 2010? This number can be anything unique, so long as it does not exist already (even a good uniqueid function would work, but I would have to query the database to make sure it isn't taken)

I bought myself a TV tuner USB stick, and the supplied software does not do what I want. I looked around for some software examples, but everything I've seen uses DirectShow which was apparently part of DirectX-9, but does not seem to be in DirectX-10. I've found AxMSVidCtlLib, but have not been able to work out how to use it.

I would like to have my application basically appear as if it was part of the desktop background, I've removed the form border etc and made the background colour of the form the same as our standard company background so it all blends in nicely. I have also made it so the app does not appear in the toolbar and it is set to launch on startup so it appears as soon as the user logs in - so all works fine and looks fine because any new apps that the user opens will open on top of my app. The only problem is that if they press the Show Desktop button (or use Windows Key + D) to minimize all apps, mine gets minimized as well and disappears. Its easy enough to get the user to make it appear again as it has a system tray icon that they can interact with, but it would be better if it just didn't vanish when they did this.Now I know the best thing for this on Windows 7 would be a Gadget but the problem is that Gadget's annoyingly have to be HTML/javascript and a) I'm not great with web coding and b) I don't think it is even possible to do what my app does from a HTML/javascript page... oh and c) I can't find any way to deploy gadgets in a business network (there is no way we are installing it manually on all 300 of our PCs), so the gadget idea is not looking very promising.I'm wondering if there is some window message I can capture and ignore in the WndProc event handler

My whole project consists of:
1. an electronic product
2. a memory stick (USB mass storage device) and
3. CD thast includes the Windows user interface program
The electronic product acts as a host controller that write data to a file (.wcs), which is in the memory stick whenever the user plug it to the USB connector. After this the user disconnect the memory stick from the electronic product and plug it to a PC that run the user interface program. Untill now the user searches for the .wcs file manually using an OpenFileDialog.
My question is:Is it possible for the program to automatic detect almost plaged or new plaged USB flash memory sticks in order to load open the needed .wcs file? If this is possible then how can I do it?

I am using a WPF richtextbox to create a syntax highlighter for code provided in a textbox. I want to have it automatically adjust the rich textbox as I am typing, using a thread timer I reset the contents of the rich textbox. I am trying to keep the cursor where it is suppose to be. I don't loose any text characters during the parse (except line breaks).
I don't know how to keep the caret position where the user has left it in the text. It defaults to the end of the document. I attempt to store the current caret position in the text and then set it to the document after I make my changes, however the error I receive is "Cannot set CaretPosition to be outside of RichTextBox." So I set the caret position to the bottom of the document.
WPF, VB.net, .net Framework 4.0
Here is the code.
Public Sub FormatText()
If IsNothing(rtfContent.Document) Then
Exit Sub
End If
Me.rtfContent.IsEnabled = False

I'm working with a project that is WPF and VB.net. I want to visually simulate "dragging" an object (though I do not want to use standard drag and drop for reason of purpose).Basically, I have a label object that, on its MouseDown event, I want it to follow the mouse cursor inside a 640x480 solid-size grid (but not outside of it!). Mind you, this grid is centered inside a full-screen window. Again, the object should not follow the mouse outside of the grid (I'm guessing a "ClipToBounds = True" here)Then, on the label's MouseUp event, I want it to either stay in its current position or return to its original position, as determined by the value of a boolean variable set by another object's MouseEnter property.Note, if it would be easier to work with, I can change the grid to a canvas in a cinch. I'm guessing that would be desirable.
How do I make the object (label) follow the mouse cursor inside the grid/canvas, but not outside of it? This needs to happen on the MouseDown event of the label.How do I make the object "stick" in its current position? (From this, I can probably figure out how to make it return to its original position on my own.

I have a program made in vb 2010. The problem is it uses my files on the computer such as different cursors and pictures and I really want to be able to make it portable and stick it on a memory stick and run it on other computers. Is this possible?
