User Makes Multiple Entries In A Single Day?
Mar 19, 2012i have an access 2007 database in wich i have a table named abc_PersonalLog, wich also has three columns: Id (auto number), StarDate (text) and LogEntry (Memo). It is a Diary application. So, when the user makes a log entry, the StarDate column receives a string formed of concatenated year, month and day, i.e. if date is 20th march 2012, the string will be 120320, and the Log entry column, the text entered by user in a textbox.My problem is that, somehow, i have to retrieve that data, when the user will want to read log entries he made. I managed to assign the text property of a label to the LogEntry text for a given date.But, if the user makes multiple entries in a single day, the table will have several rows containing the same string in the StarDate field, but different text in the LogEntry fields. How can i display ALL the LogEntry texts for all the rows containing the same StarDate value? Here is my code so far:

String Search Listbox Entries To Avoid Duplicate Entries In VB 2008?
Nov 29, 2009I 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

Dim strName As String

Modify Table Entries Based On Other Entries?
Jun 22, 2010I 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?

View 8 RepliesQuerying A Single Column And Displaying All Results In A Single Textbox?
Sep 5, 2010I am trying to make a list, separated by a comma, of entries from a single column in a SQL database. I have been spending the last several days searching for a way to do this, but every thing I found either didn't work, or wasn't exactly what I was looking for.
The query will pull all the email address that are not null. What I need to know is how to take the result of that query and make it look like this:
email0@address.com, email1@address.com, email2@address.com, etc, etc, ...
I feel like I should know this, but for the life of me, I can't remember nor can I find it in any of the textbooks I have.
I am using Visual Basic 2010 and SQL Server 2005. I also have access to Visual Basic 2005 if needed.
SqlCommand Parameter / Replace A Single Quote With Two Single Quotes

Best Way To Encrypt Entries Into 1 Log?
Apr 8, 2009I 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 ?

Using A Single Picture Box To Display A Single Picture Form A Bank Of Pictures?
Mar 22, 2011I have a few problems i need to solve. Firstly, I am looking for a piece of code i can use to display a picture from a bank of pictures. It will work on the basis of generating a random number and loading a picture that corresponds to that number.
i.e. Dim RandNumber As Integer
Dim RandClass As New Random
RandNumber = RandClass.next(1, 10)
If RandNumber = 1 Then
Picturebox1.image = picture1
[Code]...
Secondly, can I then use subsequent picture boxes to display pictures from the same bank of images, without displaying the same image? Finally, I then need to be able to click the picture or a button beneath the picture to select it as an answer to a question and then the whole process starts again.

Delete MicrosoftCom3Selfreg Entries?
Aug 20, 2009I'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?

WPF Unique Entries In An ObservableCollection
May 13, 2011I 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.
