I have an app that I'm calling up a 3rd party API.. and on each call I want to store off the patient data in to logs that are like weekly.. so on each call to the API I want to encrypt the data and push as a line into a file..I kinda dont want to open the file.. add in data then encrypt the whole file, that seems like extra work to me.so if I want to encypt the data from string to byte whats the best way to push into a file and then read out.. should I set the string to be a certain lenght so my writes and reads match up ? or is there a way to write to a data file so that it knows the end of the entry ? should I use a type class for this ?
I have a program where you have three entries, CD name, artist, price and it goes into a listbox and .txt file when closing. I have to have a message box if you enter the same CD name. I have a code to open the .txt file and compare strings but I need to change it to compare only the CD name and not all three entries. Is there a way to do my string compare against my listbox without opening the .txt file?? The program loads the listbox from the .txt file when opening. Private Sub btnAdd_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnAdd.Click' adds CD information to the list box
' declare variables Dim strName As String Dim strArtist As String Dim strPrice As String
I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute sql but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?

I've made a program for a small business that keeps track of what items there are, their prices, and the quantities of those items. I would like to add a button that goes along the lines of "Add to sale" or "Add to cart", and have it select the currently highlighted item in the database grid view to add the price column up, to make a total for a sale.

I'm using the MS example script [URL] to install a COM+ application. For uninstall I have a script that shuts down the app, calls Remove from the Catelog App Collection, and then I call regsvr32 /u. This cleans up the COM entries and removes my app from the catelog but leaves behind the CoClass and Interfaces in HKEY_LOCALSoftwareMicrosoftCom3Selfreg. How should the script remove the SelfReg values?

I have a database along with a dataset. Everything is displayed as a gridview.When I run my program and save my entries, everything works fine. I go through other forms and items are still saved but as soon as I close Visual Studio and restarts the program, the items previously saved are no longer available and nowhere to be found
I have the following code to show event log entries in my app - but it is showing them as oldest first, where I really want to show newest first and perhaps even just show the latest 5 entries
Dim eventLog2App As New System.Diagnostics.EventLog("System") Dim eventLog2Entry As System.Diagnostics.EventLogEntry Dim eventCntr2 As Integer = 1
I've never really used SQL before). What I'm trying to do is; I want to set a certain column to true or false automatically based on what value another column has entered. I managed to get this working by myself using the 'SQL Pane' in VB and testing it by using execute SQL but I don't know what to do now. I assumed that I could just save it and it would work from there but that's not the case, it dissapears from the SQL Pane if I close the project (even though it worked fine when I ran the project the first time), so where do I put it/what do I do with it in order to get this to work?
I have an ObservableCollection of class Customers that I fill from a database query. Because of how the tables are joined, I sometimes get one off entries (Bill has a shipping address that is different than his mailing address) that show up in the data twice.Each customer row has an ID as unique primary key, and this is what I use to pull up more customer information when someone selects a row from the bound ListView. In the WinForms version of this program, I would search the ListView for the CustomerID, and if it was found I would avoid inserting it a second time.
I conected my access database with the form and I need the code to count how much entries are in the database and increase that number by one, and then to write that number in one textbox so that when I press save in the form the entry would have that numbar as id.
I've read through all the search results for this and haven't quite got it yet. I often get given Excel spreadsheets of file names and have to check through them for duplicate names.I am making an app to do this for me. I've extracted the data from Excel I'm just having issues with checking for the duplicate. I've tried 2 different ways I found online and neither are working for me,
I need to count the number of duplicate entries, and provide a summary (count) for each product code. This makes it easier when the order needs to be placed, and the user don't have to count each value manually.
I have tried looping through all 50 boxes to no avail. This seemed easy, but, clearly I am to thick to think of a solution.
I have an accounts program. My cash book shows data based on date picked from DateTimePicker. Cash book is not entered everyday. I want to make my datetimepicker so that based on dates found in the database, it changes colour or enable / disable some dates, for which cash book has been entered. How is it possible?
I am trying to delete multiple selected entries from a listbox. When I run the code I have now, instead of deleting all of the items that are highlighted, it deleted all the items in the listbox.[code]
