I have form in VB.Net 2010:
I want to click-drag multi rows in dgRegister and Date, Course ID to drop in dgCourseStudent with column Date, Register ID, Register Name and Course ID.
How to code this in vb.net language?
Are there any good free alternatives to DevExpress data grids (WinForms)?I am looking for WinForms Data Grid and Data Editor Controls.
View 1 RepliesI 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?
I have used VB (versions 2 - 6) through many years; however, I am crash-course training myself into the VB2008 / VB2010 world kicking a screaming. I would like suggestions as to what SQL database access method should I focus more on in my learning process without making me feel that I'm a million years behind. I know I have WinForms where I can create a datasourse and drag / drop fields or tables on a form to create a grid (not really what I'm looking for).
My trouble isn't so much designing the form but in how I access the database. Theres XML, LINQ to SQL, ADO.NET, and many other methods. Not only do I need to grasp these methods quickly but I also need to know what type of projects I should create. What I mean is...I was thinking that I would design a WinForm app; however, I see that there are WPF apps and others to chose from. This is getting deep. I know it depends on the project that I'm working on. My plans are to write an app based off of either an SQL Express 2008 or SQL Server 2008 database. This first app will be standalone for now but may later become multi-user. I know I'm far behind on my learning curve coming from VB6. I have read a bit on VB2005 / 2008 / 2010. I own
both VB2008 and VB2010. I use VB2008 at work. I know ADO.NET is still alive but by what I read online, it's a dying method and is only kept for backward compatibility. XML and LINQ to SQL and other methods are all pretty new to me.
Is 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 1 RepliesI am trying to add multiple files to FTP server by dragging and dropping and I am able to do that using try catch block and if we give the ftp settings correctly it takes 1 sec to upload them but when we give wrong details it hangs up and dosen't give me any error message though If I give an exceptional message.
Now I am getting error message as well as success message for every file I add.I do not want that to be happen.where should I give messages for success and failure so that it should take few seconds for uploading and if not should give me a message immediately.
Here is my code:
Private Sub uploadFile(ByVal FTPAddress As String, ByVal filePath As String, ByVal username As String, ByVal password As String) 'Create FTP request

I want to know how can i drag files in controls:
such as :
1- Drag an image into a picture box to view it.
2- Drag a text file into a text box to view it.
3- Drag a html file into a web browser control to view it.
I have installed a fresh copy of VS 2008 after formating my PC, ealier i used VS 2005 for ASP. However, when open new web project and tried to drag and drop server controls to the form but i couldn't. When i click the control and drag it to the form it shows a black stop sign on my mouse cursor.... How do i fix this?
View 2 RepliesI'm trying to have either a calendar, or multiple panels representing different job duties, where the user will drag a label, or some similar object onto the panel, thus scheduling by dragging and dropping.
I've found tutorials for drag and drop in TreeViews, but I don't see how to drag a label, or any other control. I see the AllowDrop property is there, but the ItemDrag event is not.
Site is located at [URL] and the section in question is the "configurator" button on my top row navigation. Everything is written in the latest flavor of VB.NET and ASP 3.5, and I have a SQL2005 server available with my host. Here is the down 'n dirty of my dilemma:
During pageload, I get a list of all the parts in my parts table. Then I create an image object and 2 label objects per entry and place them in my fancy accordion pane control. Works great so far, I can get a giant list of pictures and text that's aligned how I like it (for now). Now - I really need a way to be able to have a visitor drag an image/label/label combo from the accordion over to a panel (or anything really) on the right side that is currently invisible. Once the dragged thing is dropped into the drop target, I would like it to fire a function or sub that I write in VB.
From what I've seen about jquery, apparently there is a way to make an element on my webpage draggable, droppable, or what have you. The example code for it - I'm not entirely understanding so a quickie sample would be great. I'm a fast learner and can apply it from there to my project. More importantly, how do I get objects that are created during runtime to be draggable, and fire my event that I wrote in the only language that I know?

I'm trying to make a program which uses drag & drop functionality, however, it only works when I drop something onto the form, not the controls. If I do try on the controls, I just get the 'Unavailable' cursor.
The AllowDrop property is set in the properties bar, and I also set it when the form loads.
Current code:
Public Class Main
Private Sub Main_DragDrop(ByVal sender As Object, ByVal e As System.Windows.Forms.DragEventArgs) Handles Me.DragDrop
[Code]....
Long time no see. I have been feeling out other languages like perl, python, French, Russian, and c sharp.
Anyway, I have this code.
Code:
Imports System.Windows.Forms.Button
Public Class ProBtn
Inherits Button
[Code].....
I can drag and drop items from my desktop or wherever and apply certain properties and values to my button (ProBtn Class) but I don't know how to drag and drop between control to switch them.
I am trying to see all the labels in Me.Controls and when I use:
For Each Control As Label In Me.Controls.OfType(Of Label)()
MsgBox(Control.Name.ToString)
Next
it only shows the labels that have NOT been renamed
I am currently developing a WinForms application in C# and require a table control that can contain other UI controls.In the following example, I would like the Links column to contain link label controls:
| ID | Name | Links |
-----------------------------------
| 1 | n1 | link1, link2, link3 |
| 2 | n2 | link1 |
Is there one I can use 'out of the box', are there any good third party ones?
Has anyone tried using controls from different sources into their application that uses winforms? Will these combination of controls work together?

I'm used to webdeveloping, and when I work with databases, I usually use some text for the Text-property of a radio button, and the row's ID as Value-property. This makes it very easy to save to databases.
Is the an equivalent in winforms for the Value-property, or will I have to identify rows based on the text in the control?
I have a bunch of buttons on a form and when the person presses TAB I want the focus of the controls move in a specific order.
View 3 RepliesI have a WinForms application that I need to dynamically add controls to at runtime. I searched for this and I was initially led to the TableLayoutPanel (TLP).
View 4 RepliesI'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 RepliesOur 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.

All 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!

In 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.

I have a Windows Forms app that, unfortunately, must make calls to controls from a second thread. I've been using the thread-safe pattern described on the [URL].. Which has worked great in the past.

I developed a VB Winforms application in VS2010 Pro on my Win7 x64 desktop computer. I also have VS2010 loaded on my Win7 x64 laptop and when I open the same solution the application's form controls are shifted out of alignment and appear slightly stretched horizontally. The VS IDE settings are identical on both computers. Any idea why the solution looks perfect in the IDE when on my desktop, but when opened in the IDE on my laptop, all the controls shift out of alignment horizontally
