.Net Forms Vs. Web Based ASP.Net Solution - Which Will Scale Better?
Nov 19, 2009
I am on a project helping to analyze the load a VB.Net WinForms application can take. This app has been in production for several years and has many many products on it. We plan to add more products but see the client footprint rapidly increasing. This is contributing the degradation of performance on the system overall.There is duscussion that moving the UI intensive portions of the app to ASP.Net it will reduce the client footprint and solve many of our issues.My question which of the following will scale better in terms of performance and load? ASP.Net(VB) Web based architecture VB.NEt WinForms 3-tier architecture

I'm wondering how do i create a User Interface that scale automatically based on the form size that the user desired.For example, we can see it in most of the modern browsers. The UI scale (larger or smaller) automatically based on the form size (try Chrome or Opera)

I have 5 projects within the same solution file, Im trying to access a form that is part of one of the projects from my startup project.I have looked through the earlier threads and most of them deal with calling forms from within a project.To my understanding ive correctly added the projects to the solution file from File --> Add --> Existing Projects.I have also referenced my Project2 from Project1 but still the intellisense does not let me access form1 of project2 from project1.

I am using 2 forms in a solution the first is the application itself (MainForm) while the second is for the settings (SettingsForm) My first question is how to let the (SettingsForm) to Inherits Or Share the Declarations in the (MainForm)? And how do I it Save Load , the settings if changed when the application is closed Some applications use *.ini files to save it's settings but I don't know how to load it back I may save it with this code:
[Code]...
I may save a settings if there a Check box by "1" or "0" where "1" means Checked while "0" means UnChecked
Also, if there is a radio button I may set the first radio as "1" second as "2" third as "3" The problem is with Loading the settings Here is the Questions once more: 1- How to let the (SettingsForm) to inharets Or Share the Declarations in the (MainForm)? 2- How do I it Save , Load the settings when the application is closed?

I can have all the projects existing in the same solution, and it builds fine. I can have a reference added to the project that I want to show a form from and still builds fine, every time I do something like this: Dim form_to_show as new Project2.Form1 form_to_show.show() It appears to corrupt the RESX file and stops compiling...it's really getting anoying..

what WPF based apps are?Is it an application that runs under Silverlight? If so, how?I know; Windows Forms based apps,console apps,DLL _ Class Library Projectsand I've had an introduction to ASP.Net.What I mostly want to know is, if WPF apps are for Silverlight then do they also run in a server based fashion like anASP.NET website would when you create ASP.Net webpages?Is it a way of creating what looks like a FORMS BASED application but it runs in a browser instead or what?Please enlighten me a bit further as I have no idea what WPF is all about.

My first post! im quite new to programming but loving every minute of it.Basically i want to open another exe file from vb.net 2010. i can do it normally using
system.Diagnostics.Process.Start _ ("c:winamp.exe") if winamp for example is installed on another pc in another location i want to run it from my program but i want there to be sort of like a settings.txt file where you can edit the path to winamp and my program should first read the path set in the settings file and then open accordingly. how do i go about doing this?
btw it would be great if you could point me in the right direction for making a windows form where one can edit the settings file within my program without editing the settings file in notepad

I am creating an Add-In that I want to create classes and forms based on a database structure. I can't find any information anywhere on how to programatically add code to classes. I know I can write out the files and add them to a project, but that would limit what I can do in the future. I would like the possibility to update a function in the future which would be impossible writing out a file and loading the whole thing back in. It would destroy any modifications made to the class, and since this Add-In will only be creating a framework, there will usually be modifications.
I got this line from the macro recorder:DTE.ActiveDocument.Selection.text = strDACode
But I like to keep Option Strict on, and this is late bound according to the IDE. There seems to be very little help on the IDE and how to use it creating Add-Ins. If I overlooked something please point me there, but I can find nothing. I don't know if it can be done, but I was able to do it in an Add-In for VB6.I would also like to add controls to a form, so if anyone can point me somewhere where it explains

I have an application that I created a while ago. It's a forms based application that runs on one of our servers at work. The app works well, BUT at the moment, requires someone to manually run it, which means having the admin account always logged in, but having the server locked.Although it's a forms based application, for the majority of the time I don't need to see the forms, so can I safely make this run as a service (by adding the appropriate code), and hiding the forms?Also, is there some code I can put in to test whether the instance of the program was started as a service or from a user double clicking on the icon? If so, I'd like the user initiated instance to run with the forms visible.

I am new to VB and I have two detail listviews with one full of items that can be droppedinto the other. I have three groups in Listview1 and I would like different forms to open up based on the group each dropped item belongs to. I was able to open Form2 on drop by adding Form2.Show() at the end of the ListView_DragDrop handler sub, but this opens forevery item and I want different forms to open depending on the ListViewGroup the item belongs to.I set the items and groups in the property windows and not in code; I do not know if this makes a difference. So here is the code I have on Form 1 where the listviews are:Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

I am just for learning purposes trying to develop a one player text based game.
I have a rich text box (GameWindow)
I have a text box (InputWindow)
I have a button (InputButton)
and a bunch of labels that aren't really important
I have two questions first is easy probably. How do i get InputWindow to respond to me hitting enter when text is in it?
[Code]...
But if i plan to have more that is only going to increase the size and code needed and im sure there is an easier way i just don't know how to do it.

I am a new to programming, trying to learn vb.net, so I apologize if my questions are very elementary or my terminology is incorrect. I am trying to format a query to an Oracle table based on user-selected radio buttons on a Windows form (i.e. the query will return different elements from the table based on the radio buttons selected). The query results will be placed in a listbox on the form. My thought was to make a Property containing my query like so:
[Code]...
and then I have a sub that feeds this SQL property (containing the query) into an OracleConnection.My problem is that I don't know how to customize that query depending on what radio buttons are selected by the user. Is a Property the best way to go about this, or is there some other way that may be better?

how to go about this? I have a form, frm1 w/a combobox, cboLocations, which is being populated using a sql string. There is also a frm2 w/a series of textboxes and other comboboxes. I want it so that once a selection is made from cboLocations, the textboxes and comboboxes on frm 2 are populated with the corresponding data. Here is what I have so far:
frm1:
Public Class frmLocations
Dim conn As New SqlConnection("Data Source=f03d3s-dev01; Initial Catalog=dos_track;User Id=vbuser; Password=tran3;")
Dim depot_refnbr As Integer
[Code]...
What's happening right now is that I make a selection from cboLocations on frm1 and click on the OK button, frm2 loads, but none of the textboxes are populating and one of the comboboxes, cboDepot, shows the different data when you click on the down arrow, but it's not displaying anything it its text field when frm2 loads.

As an ameture developer, I've never really used classes. However, I've been reading about using classes and automatic properties. I have therefore created a class which looks similar to this:
Public Class Quote
Property QuoteNum as integer
Property AccNum as String
Property Price as Decimal
End Class
The stumbling part for me comes in the way of letting form2 know which class form1 has initialized. There are in this example 3 forms to this wizard. If someone starts another wizard whilst half way through the first wizard we need to keep the variables seperate hence using the class. I think I'm along the right track, but maybe confusing myself a little.

I am trying to create a small windows forms application that demonstrates how a user can use pen-based input(ona Lenovo X220 tablet PC) to enter text (rather than typing on a keyboard) I am using Visual Basic in Visual Studio 2010.I think the control I want to add to my Visual Basic Project is the Microsoft InkEdit ControlThe instructions I see on other parts of microsoft websites refer to a .net framework componed called InkEdit. The instructions I found so far is to right-mouse click on the tool box, click 'choose items' and then select the Inkedit Control from the .NET Framework components.
