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 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?
View 1 Replieswindows service app I am developing to audit events in the Windows Security Event Log. I am using the EventLog class to read entries from the "Security" event log. I have set the log to raise events when an entry is written so I can parse the data. Here is where my problem comes in. If I run the service on Windows 2003 I can get all the data I need from each entry, but when installed on Server 2008 the EventLogEntry ".message" property comes back with useless data like this, "The description for Event ID '4738' in Source 'Microsoft-Windows-Security-Auditing' cannot be found." Under Server 2003 the message property has good data. Using the Event Log Viewer in Server 2008 I can see that it is rendering the correct data, but I am having a heak of a time doing the same. The "replacementStrings" property has the corresponding data that I need, but it appears to involve some other steps to get the data localized to the event provider, but I do not know how to do that.
I also checked the registry HKLMSystemCurrentControlSetServicesEventlogSecuritySecurity on both the 2003 servers and 2008 servers. They are identical execpt the 2003 has an entry the 2008 server does not:
String Type: GuidMessageFile
Value: %systemroot%system32NtMarta.dll
i have 7 picture boxex in 3 rows
[Code]...
On click of a picture box a new form is displayed centre screen (across the 0's), i also have a leave event that will hide the form once the cusor leaves the picture box. it seems that when the new form is displayed on top of the cusor the leave event is executed and there is a quick flicker of the form. im baffled by this because it works fine for all of the other picture boxes
I have a Visual Basic 10 program that one forms call another form.. On the called form I have a checkbox object and a 'Click' event associated with it.
My problem is that when the first form 'calls' the second form the second forms Checkbox's click event is called. it only happens when the form.show is used for the first time.
I am using a timer control to display a message form in my application, but it's not working the way I want it to. Currently, when the timer event fires I create a new instance of my message form & display it. But if the user is away from their desk & doesn't close the message form before the timer fires again, a new instance of the message form is created & shown. So how can I check to see if the message form is currently shown on the screen so multiple ones dont get displayed? This is my timer event:
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Using frm As New MsgForm
[Code]...
Do I need to use the default instance of the message form instead of creating a new one?
I have a VB (.NET3.5) project like this:
- form1: IsMDIForm = true.

- When use "form2.Show()" -> the event ItemSelectionChanged firing three time:
+ 1st: SelectedItem = 1
+ 2nd: SelectedItem = 0
+ 3rd: SelectedItem = 1

View 1 RepliesI fear that there is something obviously wrong with my code, but I have come across a situation where the Form.Load event is not firing when I create and show my form. The form is not subclassed (as I've seen some problems with that in some searches), and I am not getting any errors thrown when I step through the code in the debugger.
I have a break point set on the IDE-created form load function (which does have the Handles MyBase.Load signature suffix) but the breakpoint is never reached and the form does display and work.The form is passed three arguments in the constructor but the IntializeComponent() function is called before anything else is done.

I've read thru Iceplug's tutorial on control arrays and got it working. I tried to add a new event by basically copying his click event code and calling it a doubleclick event. I used the proper addhandler and assigned the correct name to my sub. I have the click event changing the background color to blue and the doubleclick event changing the background color to green. The background color does not change to green. Why?

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?
