this code was just working! but for some reason it stopped to work now. when i run this project the following code is supposed to execute but it does
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Dim xmldoc As New System.Xml.XmlDocument()
[code]....
In my program's Form_Load I randomly generate a time value. Once I generate the time value, I put it in a DateTime variable. I need it to work like a clock. I know I can do this with a timer with an interval of 60000, or using TimeGetTime and updating a variable.Is it possible to do this with a thread?
View 3 RepliesI have been working on them and adding to them for several months. Out of nowhere, one of the subs in my project is not recognizing updated code. I had a for loop in there that was acting funny so I changed something and noticed no difference. I messed with it for a while and decided to just replace everything in that sub with a simple msgbox and it still tries to run the code that was previously there. I have built the solution, rebuilt it, cleaned it, closed and reopened it, removed the bin and obj folders and restarted my computer several times. This is not a server program or anything dealing with IIS or anything like that.

View 2 RepliesThis may be a strange question and have no answer but I thought I would post it to see how you would go about doing it. I have a line of code:
Grade = Math.Round((Math.Abs(CorrectAnswers) / TotalQuestions) * 100)
Basically that line just figures out the grade no major code work there, what I want to do is execute that specific line with different variables without running the whole application and navigating to the point in the application which for this segment would be completing a 150 question exam, or coding some #temp page and running it from there.
I was under the impression that there was not much difference between Sub New() and Form_Load. However, I found one weird bug...Add a combobox and a label to a form, and the following code:
Public Class Form1
Private mstrOutput As String = ""[code].....
The label text shows that the value of ComboBox1.Text changes between Sub New() and Form_Load.Is this meant to happen?
I am having a problem in Form_Load. When the following code executes the form pops up with out executing any further code: Me.TblAssetsTableAdapter.Fill(Me.ITP400_IP3_ADataSet.tblAssets).
I am trying to use Form_Load to populate values in a ListBox control from an Access database table.It appears the problem was in the Compile settings. It was the 'old' problem of using AnyCPU on an x64 machine. I changed the Compile setting to x86 and the problem disappeared.
I im trying to set a time so that the user of my quiz has to do their 20 questions in 40 minutes. i actually have a few questions about the timer. How do you make it so that you canrun this same timer over everyform and then make it stop on the last form? is it possible for you to convert the timer so that instead of it running in milliseconds it runs in minutes?

View 1 RepliesHaving recently installed IIS Express I was hoping that it was going to make life easier for me, but I've run into a problem almost straight away.Consider the following which is representative of some live code:
Public Shared Function GetServiceId() As String
Dim principal As MyCustomAuthentication.Principal.MyPrincipal
principal = CType(Thread.CurrentPrincipal, MyCustomAuthentication.Principal.MyPrincipal)
[code]....
Running the code under the ASP.NET Web Server (Cassini) everything is fine and I can see that Thread.CurrentPrincipal is of type MyCustomAuthentication.Principal.MyPrincipal.Running under IIS Express this same line throws an InvalidCastException and checking the type I find it is now of System.Security.Principal.GenericPrincipal which is confusing as nothing else has changed.I can confirm that MyCustomAuthentication.Principal.MyPrincipal implements IPrincipal and remember this is Live code, it is currently deployed and working.
i wrote a piece of code to write some data to a card reader, and read back from that device, filling a form with the data (after reformat).When I step through the code while debugging (using F5, F8 for stepping forward) the form is filled correctly.However, when I run the code (Ctrl-F5), the program seems to hang for about 5 sec and then throws an exception: 'Length should be >0' When looking further during debug - it seems that the program calls 2x the Sub Frm_Read_Display().

I once heard about a software that could dynamically run dotnet instructions (C#, if I remember well) on its command line, e.g when entering 1==1, the output would be true.I don't remember the name of this soft, and sometimes one just wants to know the result of a given instruction, without having to create a new program, compiling it and run it...
I would happily take the challenge to make a soft like this on my own later, but for now on I'd just like to find this soft.Does anyone know its name, or another app which would achieve the same result? (Don't tell me PowerShell, I'm searching for something more handy.
EDIT For those who use Visual Studio and who didn't know (I just learnt about it), you can also use the Immediate Window. It even allows you to get intellisense in some cases.
I'm creating some buttons in Word 2007 that I want to use in my company application to make our teams life easier. The application is a server application but when it loads it goes through our internet explorer.If I could reveal the source code then I could get the ElementbyID to hook up the button to the text field in the application.When the application loads I can quickly right click on view the source code and it is written in C#.This is one of the id's i was able to grab
id="upEnvironmentHidden" value="PRODUCTION"
How can I make it possible to view the source code of this application...also the internet explorer will dissapear and then the application is launched.
I've almost completed my first VB.Net app which is a rewrite of an old vba app I wrote.The last part that I need to write is the timed events part. What I have in VBA is quite straightforward.Every 500ms the Timer event runs through, it checks if certain variables have been flagged and if so runs the relevent code? Code is nothing major, just updates a networked device.I've looked into timers in .net but it seems like there are various routes that I can go down.

I was wondering if there is any way to make a sub run when another bit of code has run like doing a handles event bit.The reason I want to know is that I have made a custom message box and would like to effectively create a shortcut by whereby when the string CusMsg (my chosen variable for the message box message) appears in the code and runs, it makes form3 (custom message box form) open and label 1 on that form is the writing the of the message.
