View 3 RepliesI have written a window service. and I am able to successfully install/run the service. Now I have added a timer to the service and I want to be able to adjust the interval via the registry. But I can't figure out why GetSetting("MyAppName", "MySection", "IntervalSetting") will NOT return the value in the registry!
Am I missing something? Does GetSetting() not work when called from a windows service?
In C# Windows Forms, a user control's InitializeComponent is called from the form's/control's constructor. When I create same scenario in VB.NET I don't get a constructor, and I can't locate a place where InitializeComponent is called.I need to call my code between InitializeComponent and when the control's Load event is raised, preferably still in the control's constructor. How do I do this in VB.NET?
View 2 Repliesi need to create an array of richtextboxes called rbox, and position them in a tablelayoutpanel called tlp.
i have these snippets of
dim rbox(10) as richtextbox
tlp.Controls.Add(rbox(i), 1, 1)

In VB2008 I would like to create a GUI for a command-line based exe called psftp.exe which can be downloaded here and basic usage here.I need to be able to carry out commands on the fly for example...
On Click of Button1- Connect to host
On Click of Button2- Prompt for username
On Click of Button3- Prompt for password
As these commands all relate to previous commands, they need to be carried out in the same instance of the command prompt.I have tried using the attached solution from an older post however it just doesnt work when trying to connect to a host (it works perfectly fine when using the standard command prompt).I'd also like to read any outputs from the command-line so I can create events on errors thrown for example...
On Click of Button1- Connect to host
On Click of Button2- Prompt for username
On Click of Button3- Prompt for password
If command-line throws "Access Denied"- MsgBox(The password you have provided is incorrect)My alternative to this is to buy a SFTP .NET component .
i was wondering if it possible to have a condition where lets say you have a column in the datatable called amount and a textbox acting as the filter called say maxamount to set it so the rowfilter when filtering the table will sum the number in the amount column until the number in maxamount is met, then stop and only return the rows where the total sum of the amount column is equal or less than the maxamount value, so i guess if the next row takes us over the maxamount it discards this row and returns the rows previous to it. is this possible using datagridview rowfilter or should i be loooking elsewhere to achieve this?

I have a form called FrmPracDetails which is built up with a List view called LvwColProc. Therefore when you click a field on the LvwColProc it takes you to another form called FrmColProcessing, here you can make changes to certain fields which are also present on FrmPracDetails. What I want to do is when you make changes on FrmColProcesing and Click the Save Button (which calls the Save function)the changes appear instantly on FrmPracDetails. Please note, FrmColProcessing will always be open next to FrmPracDetails. I have tried to put this code in the Save function present in FrmCol Processing as shown below, but it doesnt Refresh FrmPracDetails form. [code]
View 1 RepliesI have been developing a calculator for complex math. (Much more complicated than +,-,/,*, and above your usual scientific calculator)Its works quite well .In past programs I have used "private functions". I know that you give them a value and it returns on back. But what if you dont want to recive or send value? My example for this is a function I am attempting to make called "Autopi".The idea of Autopi is that whenever a mathimatical operation is about to be performed textbox(s) are cheked to see if they contain pi. (3.14 or 3.141) If they test positive Autopi will continue pi to however many places have been specifyed in the program. (Currently 300 places just beacuse i can :) Before the Autopi function does this it chekes to see if variable "pi" = 1. If it does it proceeds if it doesent its job is done
How would I create a code that can be called apon to activate but not recive or send any information through the program.And just to clarify what I mean by that is it will read information out of a textbox and write into it. But it wont actualy recive anything or send anything back from where it was called apon.
To create splash screen before InitializeComponent, the WithEvents statement for the BackgroundWorker component needs to be moved from the Form's Designer.vb file into the constructor as indicated in the first commented lines of the constructor below.

I have the following line of code in my program:
JCL_History.Enqueue(JCL_History(I))
This JCL_History object is basically a Generic.List encapsulated in a wrapper and has the following method:
Public Sub Enqueue(ByRef value As String)
If Members.Contains(value) Then
Me.RemoveAt(Members.IndexOf(value))
[Code].....
In my testing I have 2 items in this JCL_History list. When I call that first line of code I posted (the one that invokes Enqueue) with I = 1 I expect the first item to be shuffled to the bottom and the second item to be shuffled to the top.
After the thread returns from Enqueue I notice that this is exactly what happens to my list, HOWEVER if I hit the "step_in" button after the execution of Enqueue I go into the Default Property's set method where Index = 1 and value = and it screws everything up, because the item that got shuffled to the end (index 1) gets overwritten by the item value shuffled to the top.
So basically the set method on the default property is getting called at what I think to be a completely ridiculous time. What gives? By the way I'm running VS2005 on XP.
Can you look at my coding and let me know what I'm missing or doing wrong?I have a SSRS report that is called from a ReportViewer control and the ProcessingMode for this control is Remote. The report also has 1 parameter in it's DataSet.In the code I placed a MsgBox to make sure the code is finding the parameter and returning the parameter name. I am trying to stick the value of 10 into the parameter for playerID 10. Data for this player does exist.
I believe I need to add some more code to make this work but I'm not sure what else to add.
When the code executes the report is displayed but no data is shown in the report.

I have a large problem with inheritance in vb.net. The problem is the following:
I have 2 forms => frmBase and frmChild
In frmBase i want to create a method Called StartWorking() and i want frmChild to inherit this method.
But here is the tricky thing: when frmChild.StartWorking is called i would like the following => without calling MyBase.StartWorking()
I want frmBase.StartWorking() to be executed first and after a test in frmBase.StartWorking if blnValue is true then frmChild.StartWorking has to be activated. if blnValue is false that frmChild.StartWorking cannot be activated.

"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
