Fill Values Programmatically To Added Buttons - Efficient Way To Program?
Aug 15, 2009
want to make a custom calendar. For that I made a table of 7 cols and 6 rows and added 42 buttons in it. I added an event handler. I used this file in other form and when I click at the button the event is fired in form2. I understand this is not hte efficient way to add so many buttons. As it is a calendar, so I got to add dates to buttons based on month selected.I am finding that part difficult. For this feature, I think I should add buttons dynamically. But I can't make out how to add buttons to each cell of the table. Later on each buttons text will also change. I have added the code written so far :
Public Partial Class CalendarControl
Inherits System.Web.UI.UserControl
Public mnthNo As Integer
[code].....

I have a custom control which I add a number of to a flowlayoutpanel:
Dim drive As New WindowsControlLibrary1.UserControl1()
drive.FileSystemlable = reader.GetString(2)
drive.AbalableSpaceLable = Convert.ToInt32(reader.GetString(4) / 1024)
drive.TotalSpaceLable = Convert.ToInt32(reader.GetString(5) / 1024)
drive.SetVolumeLable = reader.GetString(3)

In VB.NET I used wscript.shell to add a shortcut to the desktop. I didn't realize it created the shortcut on the "All Users" desktop, which means I can't delete it. I don't have admin rights as this is my work computer, and asking for admin isn't an option. WScript.Shell has a createshortcut method but not a remove shortcut method! I've been googling for days with no luck. Windows XP Pro 2002, SP3.

I do a lot of programming in VS 2010 on my Windows XP Pro PC. Recently I tried testing my software on a Windows 7 Home PC. For some reason, all of the controls on my forms are slightly misplaced. I also get a bunch of unhandled exceptions I don't get on my pc. For example, one exception said it couldn't access a registry key. Another said it couldn't find the part of a path (it didnt specify which path). What's up? Why is it doing this? My Win XP PC tricks me into thinking my apps are bug free. Guess not.

Below:
datBrakePointsX.Rows.Add(strA)
produces the error 'Rows cannot be programatically added to the DataGridView's rows collection when the control is databound.'
To my knowledge, this is an empty grid. I am adding data manually and the code below works if I remove the line. The problem is I need to add the next line.
Private Sub cmdAddX_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdAddX.Click
' Find the first blank cell
For c As Integer = 0 To datBrakePointsX.Rows.Count
If Len(datBrakePointsX.Rows.Item(0).Cells(c).Value) = 0 Then
datBrakePointsX.Rows.Item(c).Cells(0).Value = c

I have a USB interface connected to my PC which is used to control DC motors (robotics). Supplied with the interface is a VB program that produces a form with text inputs (motor speed) and tick boxes (motor on/off). This program calls upon a supplied .dll for the interface. I have played around with this program and have added extra buttons to 'stop all' or 'run two motors simultaneously' etc.What I really want to do is run a sequence of events, for example:
-Motor 1 on, speed 50, run time 5 seconds
-Motor 1 off for 2 seconds
-Motor 2 on etc, etc

I have a SQL Server database for which I have created a strongly-typed DataSet (using the DataSet Designer in Visual Studio 2008), so all the adapters and select commands and whatnot were created for me by the wizard.
It's a small database with largely static data, so I would like to pull the contents of this DB in its entirety into my application at startup, and then grab individual pieces of data as needed using LINQ. Rather than hard-code each adapter Fill call, I would like to see if there is a way to automate this (possibly via Reflection). [code]...

I am building a program that does inventory control. I have multiple forms connected to same database. One of the forms I have a search function. When I was using the controls at the top of the page, it was working. I added buttons for the controls and now the database wont store anything. I can open the input form and I can add multiple inputs, close the form, open it back up, and nothing left in the database. I have also noticed that my database icon in the data source has a small red X in it. When I click on the icon, it is showing the db as closed. I can refresh it and it opens, until I run the program and it closes.

I am adding a series of RadioButtons to a GroupBox programatically. By default they are all placed on top of each other. So I use a bit of math to position them all nicely and then resize the GroupBox.
However I notice that the GroupBox has an AutoSize property, but it doesn't seem to be resizing as controls are added.
Is there a better way to position my radio buttons than to specify each one programatically? I mean, can't this stuff be handled automatically by the framework?

I've searched until my eyes and fingers feel as if they are going to bleed. I cannot come up with the answers I'm looking for. I want to essentially create an inventory system without using a database (part of why the eyes are bleeding, keep getting directed on side tangents), that is fed by the user. IE, User enters a name of a product, it is added in to an array. As a designer I will not know the exact number of elements to be held within the array. The user will enter their chosen item in to a text box. So I'm looking for a way to take the value in the text box and add it to the array. I believe I would use the reDIM function to do this, but beyond that I've got nothing. I'm unsure of how to reference the value stored in a text box.

I am trying to add NewRow to the database by using datatable in dataset, but before I do that I want to make sure that row is not already there. I create new row for the datatable I am working with, fill it with information. I fill datatable with the row from database that has the same primary key as my NewRow by using tableadapter.fill method, but when I do that my NewRow that was never added to the datatable is filled with information from database(and not information that I assigned to it). I count rows in my datatable before I fill it and it's 0, so why is my NewRow affected by Fill command? (I am using VB.NET 2005 Framework 2.0)

I have a list view with 2 columns (Prodduct and Price). I want the user to be able to add there own values to the listview and have them save so that they will always stay there.I would also like users to be able to delete specific items from the saved list.
