Getting Multiple Copy Sources?
Jan 5, 2011As a college project, I'm making a basic web browser, which contains all of the basic functions such as copy, cut, paste, delete, load a webpage, save as, print, etc. At the moment, I can copy from the HTML document, but I can't actually copy from the URL input bar. How do I do it so that when I click "Copy" it will copy the text to the clipboard, no matter what field has focus. So for example, if text in the URL bar has been selected, and the URL bar has focus, then copy that text to the clipboard; but if something in the HTML document has been selected, then copy that.At the moment, I'm using this to copy, cut, paste, etc. from the HTML document:
BrowserWindow.Document.ExecCommand("Copy", False, Clipboard)
Add Multiple Data Sources To ListView?
Sep 15, 2011Currently, I am trying to make a table, which retrieves failed products and passed products from an Entity with LINQ.
Lets assume I've done that, but have 2 lists, A regular List(Of String), and a SortedDictionary(Of String, int32) (To hold the product, and the number of times the testpoint has failed).
Now, when I want to output them to ListView, in a Webform, how can I make it, so that List(Of String), will be output on the listview, and the SortedDictionary, be output after the List(Of String)?
EDIT: Although I could just add the SortedDictionary values to the end of the List aswell, but how would I go around doing so? Because I will create a listview with 2 columns, one which holds the descriptive text, and then a List(Of String) value. And the SortedDictionary would follow, requiring two columns.
Bind Multiple Sources Of Data?
Jun 13, 2012It's been a long while since I've done any VB.Net coding and need to bind some data to a form. I have multiple tables that share some common primary/foreign keys and need to easily be able to update them.
For example, I have a table with an ObjectID, TypeID, AreaID, and several other fields. When doing my layout, I need the TypeID (found only in the main table) to be a distinct value in a comboBox, and in the ComboBox which contains the Area to be the Area Description (from the main table tied to the Area table via the Area ID).
Organize Projects Custom Controls In Toolbar As Well As Data Sources Panel?
Jan 31, 2010I have a project with 150 (i counted) Items in the "MainProject Components" area of the toolbox panel.These 150 classes are mostly database related objects like table adapters, and datasets that i hardly ever use. I also have about 10 custom classes that i use often.When i need to access the toolbox, I have two issues that i would like to resolve.
1.How do i organize the toolbox to separate my custom controls from the table adapters and datasets?
a.I have created a custom tab within the toolbox.
b.I have dragged and dropped my controls into this new area.
c.All is well until I exit my program and re-open it. Voila they're all back in the MainProject Components" tab.
2.How do I force the IDE to instantiate the toolbox panel as completely collapsed?
Asp.net - HTML.DropDownList Values From Multiple Sources?
Jul 27, 2010In ASP.NET MVC, is it possible to fill the list of values of a Html.DropDownList from multiple data sources along with multiple manually entered values?Basically, I envision it being formated like the below using something along the lines of OPTGROUP:
**Group 1**
Manual Item 1
Manual Item 2
**Group 2**
[code]....
I've thought about using a view on the DB and getting the data from that, however, I've not really the faintest how to lay it out like above using helpers and to pass the data to it from multiple sources.
Using Single Binding Navigator With Multiple Data Sources
Feb 10, 2010I have a winforms app access a database with 6 tables. Out of 6, I am showing 3 tables on three different tabs on my Form. However, I want to do it using a single binding navigator that will use / change the respective binding source dynamically, depending on the tab that is activated by the user. I have separate binding source for each of the three tables.
View 3 RepliesHandle Events And Notifications From Multiple Sources To A Main Form In .net?
Sep 23, 2011I have a vb.net application in which there is a main form. There are around 10 classes each having their own functionalities like tcpactions, fileactions, serialport actions etc. The user interacts with the main form and does certain actions which will invoke the methods in these classes. Now I have a notifications textarea in the mainform and i want to show the current action being performed in those classes and their results in the notifications area.
for example when a user clicks a "Start Process" Button in the form i invoke the method "launchprocess" in a class "ProcessActions". Now this method tries to launch about 7 different process and after launching it sends notification such as "process 1 launched" or if it fails it sends notifications such as "process 1 launch failed".
I currently use event handlers and use them to show notifications but with the amount of events i have to handle it is getting cumbersome and i might have to add even more classes in the future. So is there a better way of handling notifications from other classes.
IDE :: Set Project Default For Winforms Projects S/ Default Modifier For Controls Added To Winforms Is Private
May 28, 2010Is it possible to set a project default for VB.NET winforms projects so that the default Modifier for controls added to winforms is Private (not Friend)?I know there's a "modifiers" property in the properties window so I can set it for each individual control however I would like to change the project so from now on myself and other developers have to specifically decide to change from friend to private. (Which I would strongly discourage them from doing).I believe there is no way of doing this, but on another forum a while ago someone mentioned it would be possible with an add-in (but didn't name the add-in or where to get it).

View 4 RepliesWinForms: Locating The Relative Position Of Two Controls
Jul 9, 2010I'm writing a VB.Net WinForms application that has multiple data girds on any given form. On one such form, the data grids are loaded into split containers which in turn are located on a tab control. The load method for each data grid is threaded so that an animated "Loading" form can be shown. I would like to position the new loading form (which is smaller than the grid) on top of, and preferably in the center of, the grid that is loading. Whats the easiest way to find the grids location within the main form so that I can adjust the loading forms location?
View 1 RepliesMaking An Application That Uses Multiple WebBrowser Controls And Multiple Proxies?
Dec 17, 2009I am making an application that uses multiple WebBrowser controls, and multiple proxies.The code for changing the proxy settings are as such:
#Region "Proxy"
Public Structure Struct_INTERNET_PROXY_INFO
Public dwAccessType As Integer
Public proxy As IntPtr
[code]....
Note: getRandomProxy gets a random proxy from a list.Problem is that whenever RefreshIESettings(getRandomProxy()) is applied, the proxy will be applied to all of the WebBrowsers, while i would need to have a unique proxy for each WebBrowser. Not having this would just error out the page in the other browsers and so on.
.net - Create Custom DataTable Which Is Bindable To WinForms Controls?
Aug 25, 2011Our shop primarily use "ADO objects" (I'm referring to DataSet, DataTable, and DataRow) for marshaling around data and manipulating it on forms and in grids. We are experimenting with creating shop-flavored counterparts to the native ADO objects so that we can impose our in-house standards on top of them. Implementing this is straightforward with one exception: I want our objects to be bindable to controls.
I'm aware of IList, IBindingList, BindingSource, etc. and have looked at and experimented with these, but I am falling short when it comes to making a class with no hard property names bindable. The native ADO objects are not strongly typed by default. You have column values that you access via the Item property (e.g. row("Age") or row.Item("Age")). The binding examples I've found online deal with strong-typed objects (e.g. row.Age). Essentially, we want to create custom ADO objects (not inherited from the native ones) that still retain their ability to bind to controls. In a grid I would expect to see columns Name, Age and Occupation from a row where these properties are exposed via row("Name"), row("Age") and row("Occupation"). This must be doable as this is exactly what the native DataTable and DataRow provide.
Save Data From WinForms Controls To A SQL Server Database?
Jun 29, 2010I do have Visual VB.NET 2008 Express installed, SQL Server 2005 express installed, and I do know how to start a brand new project in VB.NET, and then add the database to the solution explorer, modify the tables/fields, etc. I know how to create a WinForm, add some controls (and name them and whatnot).....
So in MS Access I know how to use VB in the Code-Behind-Form to use the form in an unbound manner, and insert data into the tables via Visual Basic with SQL statements. I am looking to be able to begin the same sort of thing here, because I guess I have to start somewhere?

Winforms :: Why Changing Form Font Resize Some Controls
Feb 15, 2011All my forms inherits from one base form where we handle background paint and set standard properties. Recently, I think of cheching if the app is running on Vista or Later to use Segoe UI font, and I added this. The problem is than inherited forms changed sizes and their inner controls changed also... even PictureBoxes! The controls and forms seems to be thinner (in width), so square picturebox became vertical rectangules!

WinForms Text Controls - Keypress Event Handler
Mar 14, 2011In connection with a windows form's text control the keypress event handler provides a key's identity through the KeyChar property of the event argument. This works fine for all alphanumeric keys and Ctl-a ... Ctl-z, Backspace etc. but does nothing for such keys as Insert, Delete, Home, End, and the navigation keys. I would also want to read Ctl and Alt keys combinations etc. I have done these thing before, too many years ago, but forgotten it all. Tried the reference manual, but have not enough years left to succeed that way.
