Developing An Easy Radio Message Logging App

Aug 24, 2009

I need to develop a simple radio message logging app for use on a small military exercise.Now, the app is quite simple in itself, it needs to let me easily submit a new message report simply containing "from", "to", "message", "category" (and timedate, etc). Now the problem is that I have no experience with programming anything up against a database. I know basic SQL but I just dont know how to work with databases programatically. What kind of local SQL database solution works best with vb.net and Visual studio? Maybe I should use an Access database instead?When I click submit (on a new message report) how can I make an entry in a local SQL database of some sort? How can I load up a list of the message log entries already made in a listview or something?

Write A Simple Windows Form That Will Make It Easy To Record A Voice Message Before Uploading It To A Remote Web Server?

Oct 2, 2011

I'd like to write a simple Windows form that will make it easy to record a voice message before uploading it to a remote web server and sending the URL to the recipient(s):

[URL]

Currently, the user has to use Sound Record to record the message, use an FTP client to upload it to a web server, and finally, use an e-mail client to send the URL. I'd like to combine those three features into one.

Check Boxes And Radio Buttons - Value Is Not Being Updated Until I Select A Different Radio Button?

Oct 10, 2011

trying to write a simple form for calculating professor's salaries depending on their degree and position.my problem is that the when i select a check box, the value is not being updated until i select a different radio button. it probably doesn't make much sense here,

Public Class frmMain
Private Sub optLecturer_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optLecturer.CheckedChanged[code]....

the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:

UI-threading An Easy Way To Fix It?

Jan 23, 2012

I am communicating with a USB-HID device. It will successfully complete hundreds of send-receive requests but occasionally get a Null Exception error.

[Code]...

at the rxData.dataPacket(i) = element I will get a NullReference error every now and then. I could enclose it in a try/catch statement, but I'd like to fix the root problem if possible.This device is communicating to microcontrollers, and it is possible that they won't always give a value... but my feeling is this is some sort of UI threading issue. When debugging, even though there is a null exception, many times there actually does seem to be data in dataReceived.data.ToList(). Is there an easy way to place the whole data processing routine on a thread separate from the UI?Edit: Changed code to match answer and give more info on where it is used. Still get NullReferenceExceptions after about 1,000 completed send/receive requests to the HID device.

.net - VB Flamed For Being Easy And Yet Python Is Not?

Sep 19, 2010

I have always wondered about this and seen this among lots of programmers. Why is a VB programmer or VB code easily dismissed as too noobish and easy while the same does not apply to Python or Python code? After all, isn't Python as easy as VB is? And it does provide drag-n-drop GUI application building also. So why is it that VB is flamed and yet Python is not?

An 'easy' Way To Capture Video?

Apr 15, 2012

I've been trying to play with DirectShow but it's getting on top of me and my question on here didn't answered so I'm thinking maybe I should go with a different approach. (DirectShow VB.net can't change recording format). <- Where as that 'works' I can't get it in the format I want it, and I don't really understand it so I'd obviousl like to go down the route of something I can get my head around.

I've googled till my fingers are raw trying to come up with an easy way to record video in my vb.net application, it doesn't have to be fancy, just a preview with a start record, stop record button, that's it.

Easy Way To Iterate Through Objects?

Jun 25, 2009

Lets say I have 30 text fields in a Frame on my form, and I want to set them all to disable (so users can't edit them).Is there an easy way to walk through those fields without having to create an array of text fields?

I.E., in ... VB 6, with an array of text fields, I can do something like this:
For i = 0 to 10
txtfield(x).enabled = true.
Next i

Is there something in VB.NET where I won't have to use an array of controls, something like this (assuming all txt fields are in a frame):

Easy Way To Detect Internet Connectivity?

Oct 28, 2009

I saw another forum which discussed how to detect whether a LAN was connected, but I need to know whether my Internet connection from my ISP is up or not (I'm writing a program for day trading, so knowing if my internet connection is down is critical). I know I can simply open a browser in VB and browse to a site and see if it doesn't come back "page not found", but that involves a fair amount of overhead, and if the internet is down, it often takes many seconds to a minute to come back with "page not found". Is there some simple command that will quickly tell me that my internet connection is working? I'm using VB in VS 2008, and currently using XP although I plan to convert to Windows 7 in the next couple months.

Easy Way To Wait For Keypress From User

Jul 30, 2009

I want to have a one second pause after some code has run. During that pause, if a certain key is pressed, I want to do some action. Otherwise, I want the code to continue as normal. What would I use to replace the comments in the following code?

myTestCode()
' Wait one second and see if a given key was pressed.
' If specific key is pressed, then show messagebox (or whatever) asking user if we should cancel (whatever)
NextMethodToRun()

Yes, I know there are a number of ways, which is why I am looking for something that is fast and simple to use. I do not want a console window, some other form, etc. to appear. Just want to check if a key was pressed. The key (if pressed) should be pulled off the keyboard buffer.

Collection To Place These Objects In For Easy Reference?

Nov 11, 2011

I have an error while using a collection that has been stumping me for years.I wrote a class to allow users to write equations in a txt file using RPN (stack based notation).The class runs through a select statement while reading the equation and then ends up with a final number as the answer. I have a collection to place these objects in for easy reference. For whatever reason I get random object reference not set to an instance of an object errors when there is nothing in the program that would remove objects from the collection, kill objects, or change the collection in any way. It is possible for one thread to call the calculate function while another thread calls the CurrentValue property. I'm not sure if this could be causing the error, but once it happens I get an error every time the program enters that code until I run out of memory.
