VS 02/03 Cannot Display Contents Of A Queue In Message Box
Dec 16, 2010
I am currently going through Murachs Beginning vb.NET and have come across an problem with one of the exercises at the end of the chapter on collections. I basically have to update a simple Invoice application that was developed in an earlier chapter.It requires me to update the app such that everytime a new invoice object is created ( via pressing the new invoice button) this object is added to a queue. I am ok with this part.However I then have to edit the exit procedure so that the invoice objects are dequeued and displayed in a message box. This is where I am having my trouble. My code so far is shown below. This consists of the form.vb and the and the Invoice class.[code]I have also added a diagram of the format for the message displayed in the message box. I know I have to iterate through the queue but how can display the invoice customer name and invoice total?
I have a program that is using API's to send mouse events and keyboard events to another application that is running. I need to know how to tell if there are any messages left to process for that window after I have click on a button or moved to the next field. I need to know this so I don't send any more mouse or keyboard events until it has finishing processing everything in its message queue. An example is that I click out of the key field and the form has to go out and read a client record. This may take a second or two, so I need to wait until the form is ready for more input.
Im a newcomer for Sonic JSM queue. I need to send an xml message to a JSM queue. I can send a string message using following code.Dim msg As Sonic.Jms.TextMessage = SonicSendSession.createTextMessage()
I am processing a local message queue and every now and then getting an "Insufficient resources to perform operation" error message when there is over 2GB RAM free.The queue is very small (often only a couple of items (if that) and never exceeds 50 items), with the items themselves being just a very basic class that consists of a filename (as a string), two integers, two booleans and one enum (i.e. very little actual data)In order to check the size of the message queue, I have a timer that ticks every 5 seconds, and when it does calls the following code:
Private Function GetQueueLength() As Integer Dim QueueLength As Message() = ProcessQueue.GetAllMessages Dim Length As Integer = QueueLength.Length[code].....
I am using a message queue successfully as I am testing while I am writing a new program. (This is my first time using a message queue.) I have to have multiple instances of my program running, so I was wondering if this would be a problem with the queue? I have tested it and it looks fine, but I didn't know if it is by coincidence, or if the queues were separate.
This is the first time I have used this messaging library and used some example code to implement it. The first time I ran it it worked perfectly but I abruptly stopped the code since my parsing method seemed wrong. So when I restarted it, the code freezes at the following line:
I'm struggling to write the contents of a dictionary to a message box. Ideally I'd like to write the contents to an XML file, but I'm having difficulty even writing the contents to a message box!Im using basic code to get me started....
Dim users As Generic.Dictionary(Of Integer, String) Dim x As New Dictionary(Of Integer, Users) x.Add("1", New Users("1", "Joe"))
I have a richtextbox contains Texts and Table. Now I want to send this richtextbox contents as email body message including table lines, is it possible?
Dim Mm As System.Net.Mail.MailMessage FrmMail = "onel@dreamincode.net" ToMail = "mahey@dreamincode.net"
I am working on a 1-page report, that basically consists to select 1 record from table and bind values to proper fields (eg. =Fields!name.Value).However, I have one field in the table that will be just "Y" or "N".When this field will be "Y" I would like to show in the report "Yes, I do."; otherwise I would like to show "No, I dont."
I have a problem in timers, I want to display 2 forms each one after 3 and 5, how to do that? I mean when the first form appears, after 3 seconds another one will appear, then after 5 seconds the second will appear. I have a code where someone gave me here but its for message box only, thus I modify it to put a form still does not work. Here the code I put in the timer below:
Private Sub frmblabla_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load tmrnote.Start() Private Sub tmrnote_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles tmrnote.Tick[code]....
I still have problem when the message box stops, it displays all the forms together. All I want is when the message box stops, then it display the first form then stop to display the second then stop to display the last. The first form must stay for 3 seconds on the screen, then after 3 seconds the second appears then after 5 seconds the last appears.
