I am trying to get both text box to read the military times. If either time is invalid the "enter valid, the "enter valid input" message box should display. In my validMilTime I tested both hours and minutes. I am not sure if I wrote the code for minutes correctly in the validMilTime to test minutes. I test it and it goes directly to "enter valid input". I want it to read "both times are valid" if I put 1200 and 1400 in both txtStart and txtEnd textbox.
Here is my code so far:
Option Strict On
Option Explicit On
Public Class frmMiltime
Private Sub btnEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEdit.Click
If ValidMilTime(txtStart) And ValidMilTime(txtEnd) Then

I have a list of 100 assets that are pulled from AS400 and shown on a gridview alongside a dropdown box with 6 possible status and a textbox.
If the user selects a status other than "Found" (whether it's "Not Found", "Scrapped", "Sold", "Transferred","Other"), the user cannot leave the textbox empty. They must insert a comment into the textbox. Once the user is done he clicks "Save" and if, let's say, the status is "Sold" and the textbox is empty for all assets then a Message Box pops up saying "Please fill the textbox".
The problem is, the message box pops up 100 times (or once for every asset that has the error).
1) What can I do so that the message box only appears once even when 100 assets have the error?
2) Also, when the message box appears and I click "OK" the information the user had filled up to that point gets erased.
SAVE CLICK EVENT
Protected Sub Save_Click(ByVal sender As Object, ByVal e As EventArgs) Handles Grabar.Click Dim comando As String = ""
how to create an error message by message box to tell the user to enter a number only if they key in a character value?
I MEAN AFTER THEY PRESS THE CALCULATE BUTTON

I'm saving military time into the database. Then I need to pull this data back out of the database. To get just the time without the date I can do this:
This seems so simple, but I can't get the answer. I need to get the current time in an hh:mm:ss or sss military format. By military format, I mean that if it is past noon, the hour is the PM time plus 12 (1 PM is 13, 5 PM is 17). I found this bit of code:
[Code]...
It returns the hour in AM/PM format. That is, if it is 4 PM, it returns 04 rather than 16). I can't find documentation on the hh:mm:ss mask. In fact I can't find a simple discussion on how to make the time of day property return time in various formats. After 3 hours of futzing around,
I am trying to learn a little more about reading and writing Outlook mail messages. So I've written a small app to read my mail messages and pull certain lines from the body. When I run the app I get to a certain point and start getting error messages telling me I have a limit on the number of messages I can have open. With that I figured something is not closing properly. All of the examples I've checked out (I've been at this most of the morning) I've not seen one thing where the code is closing the message after it's been read. I've included the code and as you can tell there's not much to it.
I am able to query/read the "Application" event log using System.Management classes in VB.net 2005 (win xp)But I have problem reading the "Message" / "description" of my custom event log.I am getting a System.NullReferenceException{"Object reference not set to an instance of an object."} while reading the "Message" / "Description of the event log while it is reading the others properties.Also when I use System.Diagnostics.EventLog and read all the Events on by one I am able to read the message/description of my custom event log. Why is that the System.Management classes can't read the my custom event log messages while the System.Diagnostics.EventLog classes can read them.The reason I want to use System.Management classes is bcoz I can query my custom event log where as with System.Diagnostics.EventLog classes I have to read the whole event log.

I know it's possible in asp.net to create a custom error page in a web app, by putting the following line in the web.config: <customErrors mode="RemoteOnly" defaultRedirect="frmErrorPage.aspx" />
I have had to do this for my web app, since it is clearly much tidier than letting the program bomb out with it's ugly default error page. My custom error page just has the customer's logo and a brief message saying "Error has occurred. Please return to homepage"The trouble now is that I have no way of knowing what caused the error, when a customer reports it.
Is there a way to make the actual error message appear on this custom error page too?
I dragged and dropped a label control on my web form. But then whe I go to my VB .net code behind file, if I try and set a property on that label control, I am getting a "Declaration Expected" error message for the label I created.Yet if I do try and explicitly declare my label control, the compiler tells me that the label control is already declared.[code]

When I run the code, type a value in quantity and hit the calculate button I get an error message stating, "Quantity must be a numeric value" and I don't see in the code what I have missed. I thought I set quantity as a numeric value by making it an integer and parsing it.

What I am trying to find is a way to get the current time and find which list item it fits into. What I think I need to do is to first of all get the current time and then go through the list splitting each item into 2 times and seeing if the current time fits. For example: Split the item 00:00 - 00:14 to 00:00 and 00:14 and then check if the current time is more than 00:00:00 but less than 00:14:59 and if so do certain task.how to go about taking each list item and splitting it into 2 separate times so I can check between them?
