VS 2008 Conditions Met, Message Box Still Appearing?
Apr 8, 2011
This is something probably very simple for you all by the looks of these other thread but I can't figure it outThis is a hotel reservation order form.IsFormComplete function checks to make sure the form is complete, if true it calls GetOrderList which... well you get it.The problem is this:I have checked functionality at random and everythn there is an error, message box displays what is wrong... except one thing. When you complete everything but choose cash as the payment method and click place order, the message box pops up with the GetErrorList caption "Please Complete the following:" BUT there is no error reported after. I'm losts, I know, it's probably terribly written to begin with but I'm all of a week in to the class so I will get there.
Option Explicit On
Option Strict On
Option Infer Off

Basic out line connecting to an irc server. We connect to this server using a TCP client on a separate thread from the UI. Now the raw numeric for the MOTD is "372" so when our streamreader reads this value from the worker thread it raises it's value and displays it to a RTB. Now my issue. When i connect to a server i wait till raw "372" before i check to see if i need to join a channel. But a lot of servers have more then then one line MOTD each sending there own "372". So if a server has a long MOTD that could mean over 100 "372".
Now while it does not effect the UI of my app i wish to move the "372" to it's own thread from the current worker thread. But thats the problem. How do i move the MOTD to it's own thread when it's still being read.

I made a web browser using the Visual Basic Language. I am having a problem with the WebBrowser Control.If I go to a website that runs scripts (i.e.; sports.yahoo.com), a message comes up:"An error has occured on this script page", Do you want to continue running Scripts on this page "yes, no". If you click yes or no, the same message appears for 8 more times. Is there anycode I can use to disable the "Script Error Message" from appearing in the WebBrowser Control.

I am trying to write a Function which will return a data table, filled with a data from a database.
The Function will accept 6 diffrenet parameters as Optional. Each one of them will be an additional condition to be added to a where clause, if it`s provided when the function is beeing called.
Is there any method in .NET to simply add a new condition to the where clause?

I created a context menu so that when I right click on a file name in a list box, the context menu is displayed.
Private Sub ListBox1_MouseDown(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles ListBox1.MouseDown
If e.Button = MouseButtons.Right Then
[Code]....
The problem instead of appearing just over list box, the context menu is appearing even outside my form!
How do I make it appear just besides my listbox?

I am puzzled by a delay in my data appearing (sql sever) when I open my program. (this can be around 5 to 6 seconds). If I open it a second time it appears instantly, have I done something wrong, or not done something. I have connect to a MS access database that connection is instant always.

I am making a Bingo game. I have a button which keeps on calling numbers which are then added to a list box. How do i make it that the numbers called don't repeat (get displayed in the "number called" label). Is there a way to use items already added in the list box to eliminate duplicate numbers.

whenever my program crashes at college, an error message pops up in a window which tells me why the program crashed and points to the line of code which made the program crash. I have recently taken the program home to finish on my own computer but now whenever it crashes nothing pops up to tell me why it has just crashed.

I have a ListView that I populate with running processes and would like to highlight specific rows based on the amount of memory consumption. After I add the processes to the list and and call the WorkingSet64 property of the process, I tried this:
vb.net For Each lvi In ListViewProcess.Items If proc.WorkingSet64 >= 2000 Then lvi.BackColor = Color.Yellow End If Next
Processes is the variable I used to grab the collection of processes. proc is defined as a variable and then used to loop through the processes.
lvi is of course the ListViewItems in the ListView.So, by the code I have above, I loop through the ListViewItems, and if any of the processes are above or equal to 2000, then I set the background color to Yellow.
However, it sets every line to yellow, and I can't seem to figure out to set only those processes that have a WorkingSet64 above 2000.
Would I need to loop through the processes and then set the background color of the ListViewItem based on that? That kind of makes sense to me, but if I do that, I'm not sure how to set it just for those processes. Maybe by setting a separate variable?

I added an "edit" icon on my bindingNavigator. When users click on it, a new form will come out and pull out all the data records from the datagridview. Now the strange thing is that when I wanted to edit the data records, when I left the product name blank, I would get an error message saying "Product cannot be blank" - please see above code. But when I left the "Cost Price" blank(same applies to "Sell Price" and "Quantity"), the error message box wouldn't come out, instead, it did not allow me to move on to another textbox, close the form etc until I filled out that textbox with INTEGER. May I know why the error mesagebox would not come out when I entered the wrong datatype?

I am very new to vb, I know there is an error somewhere, I had an assignment which stated that if a number was < 101 or > 500 and the answer is correct the output should be, for example-123, if the answer was wrong then the message output should be wrong number <101>500. Everytime I type in a number(no matter what the number) and click on my check button I get the output message. If at all possible, can you please assist. My professor gave the following example, but I am still not getting it:
Dim strInteger As String = "52.801"
Dim dblNumber As Double
dblNumber = CDbl(strInteger)

So I am trying to evaluate 3 conditions in an if statement. Its not working how I would assume it should. I basically want to do this:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 And (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
If I write it in that manner it gives inconsistent results. If I workaround by writing it this way it works perfectly:
vb.net
If PGN = &HEF007E And PGNData(0) = &H58 Then
If (PGNData(1) And &H40) = &H40 Then IgnOn = True Else IgnOn = False
Endif
What is the proper way to do this with only one if statement?
