Once The Timer Has Been Stopped And Started, Code Does Not Goto The Elseif Part (i.e. I=5)?
Jul 19, 2010
i was trying to make a free microsoft word plugin in vb.net. It automatically fills a web form. The main problem with the plugin is that it uses web browser control and once it has filled a form it will need to navigate another form. The form can only be filled once it has completely been loaded.so my approach is
1. navigate to first site when form loads
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
WebBrowser1.Navigate("http://google.com")
End Sub
2. use an integer i and use if statements to check which form to fill :
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEv entArgs) Handles WebBrowser1.DocumentCompleted
If (i = 1) Then[code].....
3. this is the main step. you see when main form loads, i=1 so browser goes to google.com (first form), when form is completely loaded, itchecks for value of i. Since i=1, it fills google. After filling and continuing i=2 and browser goes to my personal account page. This means browser again loads the document. Now i=2, so it fills my personal detalis. Now the timer starts. Since i=3, browser navigates to second site and fills the details.
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
If (i = 3) Then
WebBrowser1.Navigate("http://blogger.com")[code]...
now the problem arises. The browser does not go to the third site. Once the timer has been stopped and started, the following code does not goto the elseif part (i.e. i=5) why is that so?
try 'code goes here catch ex as exception end try next
now, in my code, i also have if ex = certain error. i'd like it to go back to the top of the try. reason for not letting it do its thing is, i am wanting it to retry it, under the same item. So, is there a way to goto a portion of the code.
All, I have a Custom object which I have written using VB.NET (.net 2.0). The object instantiates its own threading.timer object and carries out a number of background process including periodic interrogation of an oracle database and delivery of emails via smtp according to data detected in the database. The following is the code implemented in the windows service class [Code].
After a little bit of experimentation I arrived at the above code in the OnStart method. All functionality passed testing when deployed from VS2005 on my development PC, however when deployed on a true target machine, the service would not start and responds with the following message: "The service on local computer started and then stopped..." Am I going about this the correct way? If not how can I best implement my incident manager within the confines of the Windows Service class. It seems pointless to implement a timer for the incident-manager because this already implements its own timer.
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Hide() Dim value As String = """" + Application.ExecutablePath + """ -nogui"
[code]....
I want the program to exit the sub after the timer has been started. But if theres no args, it should just show itself. The problem is that it seems to not care about the exit sub thingy, cause it shows itself anyway.
I've seen a few people on here saying that you shouldnt use GoTo in VB.NET and to be honest I've tended to agree as I have never needed to use it and there is always another way of doing something without using it. However, I'm just wondering what is so bad about it? I actually noticed that Microsoft seem to use it a fair bit in the internal .NET framework code, which is what makes me wonder why people are so against it.
I want to know if there is a way where i can view the code that my computer sending threw the cpu so i can learn it is there a program i need to so this
This is my first post..and it is a question. Hope some day I will be able to provide also answers... I started a third-party external application using Process.Start function. Does anybody know how I can code a click of a certain button in that application (the name of which I know)?
I am using DataSet.ReadXml() to create a DataSet from the following XML file, so that I can quickly query it using Linq.[URL]..I then use the following object to create a DataTable which can be used as a dictionary, with a ConvertToFriendlyFormat function that takes an Emulator_Id and and a string that corresponds to a DicEntry node's StoredFormat attributed, and return the same node's FriendlyFormat attribute.
This does work BUT it is extremely slow (~11 seconds to call it ~220 times). I have been unable to figure out how create the DataSet when the object is initialised and just query the simple DataTable in the ConvertToFriendlyFormat call. I guess this is what is slowing it down?
I'm currently making a code that will login to a cisco router, and show the version, then return the version to me. The connection to the cisco router is using telnet, and I'm using Dimac's w3Sockets code to Connect, login, and return data. Reference
But currently I'm having some problems, since the router sometimes need the login typed 2 times, or having a key pressed to update the terminal(telnet),meaning i have to check if it gets logged in or not. But the problem is that using dimac code, i can only wait() and waitFor(), and if it none data comes whilst waiting, it keeps on waiting. Is there away to do like: "if wait fails goto"
I've tryed "on error goto", but since its not a error, but just keeps waiting, that dont work. Also, To locate where it gets stuck I have it write to my textbox everytime it takes a step in the code, but its like the dimac code overtakes vb.net. ex: If i send some text to a textbox in the same sub as the connect code is, and it gets stuck at a wait, it dont even write to the textbox, eventhough the textbox.text command was suppose to execute before the wait().
Code:
Private Sub telnet(ByVal port)
TextBox3.Text = TextBox3.Text & Environment.NewLine & "Telnet func Called" 'Cant execute this if it gets stuck at login below. ?? Try
I would like to get some input as to how I would create the same code without a dreaded "goTo" statement. This is something i've wanted to get an answer to for a while and just thought about it again.
Quick question - if I have a timer set to 5000 (5 seconds) and the code in the timer takes longer than 5 seconds to run because of sql stuff, will the timer wait until the code is done till it fires again?
I found this code to check internet connection on MSDN, but I am getting errors on the part of the code in bold, saying they have not been declared. how to declare these two things? I mean 'InternetGetConnectedState' and 'Flags'?[code]...
Suppose I have two buttons btnCheck and btnOK. I want to execute few lines code of btnCheck from btnOK. So that When I click on btnOK, btnOK's code as well as BtnCheck's Code should be executed one after the other. How can I do this in vb.net
I'm wondering if it's possible to refresh only a part of a code, the reason why is that I'm adding an item from Form2 to a listbox in Form1.The code in Form2 for adding is : [code]I need to press a button in Form2 to trigger the refresh in the code I posted above + it needs to do this action.[code]
I seem to be having a lot of trouble with this project. I am trying to update this atabaseI know that the routines are working (atleast the delete and update of records),but it seems to be going straight from the If statement right to the End If and not attempting the ElseIf statements. If it is something simple...sorry for the dumb question, I'm very new to rogramming in general.
Public Sub Delete() Dim lngRecordNumber As Long Dim StartTime As String
I have the following portion of a VB Script, and for whatever reason, no matter the input data the first If statement is successful, which is cauing incorrect data in my output file.
Script excerpt (this is a function):
On Error Resume Next code goes here If Err.Number = 0 Then WScript.Echo "It worked!"

I have a HTML file (for example filename.html) with a HTML code (div, paragraph, ecc...) and HTML Table.I need extract only HTML TABLE from source and conver it into XML datafile.[code]...
I've got a DateTimePicker control on my form. The normal behavior is for it to allow the user to "move" between value fields with the arrow keys and remember the last date part that was highlighted when the control loses focus. Then, when the control gets focus again, that date part is highlighted. We all know this, I'm sure.What I want to know is how to access the control's selection properties/methods in order to have my DateTimePicker control always highlight the month portion when a user enters the control, regardless of what the last date part highlighted was.
Assume I have an If-ElseIf decision to make. Do all ElseIf's get executed after one has been found true? [Code] Obviously that is not a real subroutine but I wrote that just to clarify what I'm asking. When this is run, on the second ElseIf the value is equal to 5 so whatever is inside that ElseIf would execute. Once that happens do the following ElseIf's get checked or does the program immediately go to the End If?
Since plan1 and plan 2 all plans having same fields but due to their variable values total I make 4 tables having one to many relationship so that duplicate data for few fields get accomodated under different Id. and now there is no need of filtering data also and 4 databinding sources give a serial values to my comboboxes to select veriables to get further calculations.
I have another question now in further calculation there are many calculation sets with using if elseif if statment for such number of sets how to connect them since in form1.vb code file
if I place them one after other some calculations get correct some gets wrong.I hope you understand my question.is there any method to connect such sets( if elseif if) statments one by one under one buttion_click to get correct answer for all the sets.
What is the difference between nesting an 'If' statement in and 'Else' statement and using an 'ElseIf' statement? In the example below, the controls labeled [nAMEoFdAY]Limit are instances of the NumericUpDown object, each representing a day of the week. I need the application to decide which NumericUpDown to draw the value from based on the current day of the week. Will this code work or should I use the 'ElseIf' statement, and if so, how?
I have created a class which generates a form in code. I have hooked up the buttons and a text box so that they work. Now, I am trying to hook up the Resize event (and probably will need other events) for this form. How do I do that? If I can understand how to do it for the Resize event, I should be able to apply that to whatever other events I might want to use. I can't just put "Handles frmMyForm.Resize" or "Handles Me.Resize". I get the message "Handles clause requires a WithEvents variable defined in the containing type or one of its base types." This all has been a learning experience.
I have a BIG piece of code that looks like this: Public Sub mnuNew_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles mnuNew.Click ' Lots of code End Sub I need to execute this subroutine from another part of the same form's code. This should be fairly simple but I haven't been able to figure it out. How do I do this?
I've made some function that generates an email template. Code it generates is pure HTML with CSS. Problem is compiler does this odd error and highlights each time '#' sign appears which is needed to define colors in CSS. I did try to change '#' to '/pound/' and then string.Replace() on RETURN but no luck. I'm more into C# so there i can escape special characters by using '' before them but something f$#$ed up there... Once i remove '#' all back to normal and compiles well.
