Store Info During Application Runtime?
Jul 1, 2009
I am making a video conversion tool. I have a listview with one item per file.And i also have options to add subtitles to movies. I want it to be like this:Say the user add 2 movies. He select the first movie in the listview and then go to the subtitle tab beside. There he checks a checkbox so he can add subtitles. Some controls comes up that allows he to browse for subtitle and select which language the subtitle is. Then when he has selected these options, he select the other movie, the program saves the subtitle data somewhere and then erases all fields so he can fill them with a subtitle for the other movie.
My.Settings is way to simple for this. But i don't want SQL or db related stuff.Is there a good storing way i have missed?

I have just added a login form to my main form which just has a username textbox and a password textbox. What i basically want a user to be able to do is enter their username and password into these fields and then for the form to store the values there.
So if they enter their username and password, and then click OK on the login form, if they were to open up the login form their details would still be there?I want to be able to call on these values else where? How do i store the info in the username and password fields? And if they then closed the form and opened it up again would it still remember what username and password had been entered?

I am trying to learn VB.NET and I've written a user entry screen to store and retrieve information. I keep getting this error. I understand that I have to either change the ref value from the calling code, but my problem is where is the calling code? Here is the error I'm getting (the program is underscoring udtTrans in the FileGet line in this segment).
Private Sub viewRecords()
'open the file and read fields of the first record into the textboxes
Try
FileOpen(1, strFilename, OpenMode.Random, OpenAccess.ReadWrite, OpenShare.Shared, Len(udtTrans))
FileGet(1, udtTrans, intCurrentRecord) 'gets first record

I am trying to come up with a way to store 3 pieces of information for each employee in the company on a daily basis. So for instance:
Day 1: Joe, 8, 80
Day 2: Sam, 10, 90
Day 3: Bill, 5, 40
Day 4: Bob, 8, 40
Day 5: Sue, 2, 50
I am very new to collections and most of the applications that I build are Create, Read, Update and Delete type applications that don't really need arrays so I have almost no experience with either.
This is what I have so far.
VB
'
Dim iDays As Integer = NumberDaysPerMonth(Date.Now)
Dim DayNumber(iDays) As Integer
Dim EmployeeRecords As List(Of String) = New List(Of String)
For i = 1 To DayNumber.Count - 1

I am writing a program that lets someone click on a picture to vote for their favorite pet. The part I am stuck at is: when the application is opened and closed it needs to remember how many votes there were. To do so, when the program is closed I have the information stored in a .txt file. it looks something to the effect of:
name, type, votes
andy, bear, 0
bart, dog, 0
candy, cat, 0
hopsie, bunny, 0

know open an xml file into a datagrid. The xml file is stored in a secured ftp with username and password. Just as an example if the site ftp.mysitesite.com, with username "xxx" and the password "XXX" has the file 123.xml, then how do I load 123 into a datagrid. Is it possible to store these info to a variable in app.Config and use that variable to access the site?

I am wriing a vb.net windows application to log and store information. then display it in a sortable multiple column listbox (I personally like FlexGrid by Component One). However... I am not sure how to go about storing the information. Should I go with a .sdf file database, registry, simply storing them in a file, or some other method?
What I need is to be able to:
read/write/delete from it
read possibly up to a 20mb file and sorting it without a lot of lag
be transported to multiple systems and maintain these writes (installed on many systems)
I know I could split up the reading/writing to anther thread. Even to other .DLL's and whatnot. But as for storing. Not sure what the best option is.

I forgot to add "Inherits ListViewItem" to my class.I'll update the code listed here to serve as an example for others.

Let's say 10 desktop shortcuts, all with different names/icons, point to and can start the same exe application from the same directory. Is there any means for the application to know the distinct name of the shortcut that was doubled_clicked. Also is there any means for a running application to know if it was started by command line, by a double_click on the exe, by a double_click on a shortcut that points to it, or by another process' call?

Which is the best way to store application and user settings of an application running with multiple instances?My problem is that using the vb's "Application Settings" one instance would overwrite the other one.I want to identify each instance with a number passed via command line argument. I could use this number to identify the appropriate settings of the running instance, but I see in a local INI o XML file a better way to handle that.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click
Me.Close()

I have a 3rd party program that has an internal messaging system built into it. The messages are stored in SQL. What I am doing is writing a program that will query this database on a specific interval and if it finds a message for a specific user it will take the text of that message and send it to the users email address(ie. gmail, yahoo, etc.). The issue is when the program quesries I only want it to grab the message that have not been sent. Each message in the system gets an ID assigned to it so what I'm trying is everytime it finds a message to send to the user it will write the ID of that message to a text file so that next time the query comes around it will compare the ID in the text file to the most recent ID in the database and if it is newer message it will get it and send it. I'm not trying to display any data from the query, just take the messsage text and send it.
Public Sub LookForMessage()
'Bind database tables to datagrid view
cmd = New SqlCommand("SELECT * FROM dbo.tblMessageTo", con)
cmd2 = New SqlCommand("SELECT * FROM dbo.tblMessages", con)

There is one exception, and it's the reason I'm posting here for assistance.On one machine that is a Dell Latitude running Windows 7 64 bit with .Net 4 Framework installed the console application will crash immediately before it starts Sub Main. It simply give the generic windows error "A problem caused the program to stop working correctly." with no option to see debug info.

Through COM, one can potentially gain absolute control over a target system. For example: using javascript's ActiveXObject object in IE, one can create certain objects which were designed to have direct access or interaction with system properties and files.One would think common sense dictates users disable ActiveX features in IE immediately after installing the browser to ensure their system is protected while surfing the net, or at least paying close attention to which websites they permit. But, I doubt many average PC users know how or why to do this, or just get tired of mirco-managing it over time. I think any PC user or admin my COM class caters to would greatly appreciate not having to deal with that. Thankfully it looks like IE versions come packaged with ActiveX disabled by default nowadays.
I've built a very versatile COM class library in VB. I didn't intend for it to be callable from any website, but that feature is just part of the COM platform. I'd like to prevent the library from being called from IE unless the website is on a white-listed domain to proactively protect the user (and ultimately their entire intranet) from harm from malicious websites. What would be the best method in VB.Net to tell which application called my DLL, to be able to tell if it was called from any command or process originating from IE? And, what domain called my dll? System.Environment.GetCommandLineArgs()(0) gets me the calling application path. With this info, I can compare it to a black/white-list of applications.

About 5 years ago I wrote this program in Excellusing VBA to compute commissions, income and expenses for the real estate agents in my wife's business.The company is made up of about 50 agents. Part of the program includes a combobox on a main form when a name was selected it also selected, the agent id, and the split the agent was on. It would calculate the split expense that my wife got by multiplying the split percentage from the combobox times the total commission.The main form also contained various other comboboxes, list boxes, and text boxes to gather such info as property address, selling price, titles company, transaction credit,income,Once all the info was complete my wife was asked if she wanted to save the transaction. If the answer was yes, the info was transferred to the permanate database, a commision report for the agent and my wife was printed out, and the temporary database was cleared.

We're using team build with AssemblyInfoTask to increment the build number in a nightly build. The build number is displayed in the application using My.Application.Info.Version.Build.This has been working fine for years. But since we branched the sources and started using file references instead of project references (have no idea if that's what causes the problem), the last build number is displayed instead of the current one.
The compiled files (dll's and exe's) have the correct build number, if checked by right clicking the file in Explorer and viewing detailed properties. However when the same exe-file is executed, the UI displays the previous build number.If I edit the AssemblyInfo.vb file manually (just set another number, save the file, and set it back again), both file properties in Explorer and the UI at runtime displays the correct build number. How can this happen? What can be done to avoid this strange behavior?

I have a problem where I am running a Console App to obtain some computer information on a pc. The pc has the following specs:
Windows XP Media Center Edition 2002
Service Pack 3
2 GB RAM
.NET Framework 3.5
The script runs fine on my Vista Ultimate PC. However, my friend runs it on his pc and nothing is written to the file. The directory and the file are being created, but nothing is in the file. Is there something that I am missing about XP Media Center Edition?
Here is the code:
Dim cFile As String = "C:System InformationsystemInfo.txt"
Dim objWriter As New System.IO.StreamWriter(cFile, False)
Try
Dim mObjOS As ManagementObjectSearcher = New ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
Dim mObjCS As ManagementObjectSearcher = New ManagementObjectSearcher("SELECT * FROM Win32_ComputerSystem")
