For Loops - Determine Which Students Have A Specific Major Based Upon The Button That Is Clicked?
Dec 15, 2011
I need to determine which students have a specific major based upon the button that is clicked , then code will pull all the CS student's name and put them in the results list box. The text box above the results list box should contain the specified major and the text box below the results list box should contain a message indicating the total number of students with specific major.

Private Sub Answerbtn3_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Answerbtn3.Click
Me.Focus()
Form2.Show()
and on form 2 load event i have

I'm running into a little problem making one combo box dependent on the selection of another combo box. I'm using a access back-end to this project. I have two tables: MajorCategoryTbl and MinorCategoryTbl , MajorCategoryTbl has PK and description field, MinorCategoryTbl has a PK, MajorID (foreign key), and description field. I have two combo boxes on my form, one that displays the Major description, and one that displays the MinorCategoryTbl description, but the stored value is the PK for both. I want the selection of the minor category combobox to depend on what was selected in the major category combobox.

I have a program with 32 PictureBoxes (pb1 ... pb32). The user will select one of the picture boxes. All picture boxes will call the same subroutine, passing the variable of the name of the box clicked. Rather than writing a click event for all 32 boxes, and call the same subroutine from each event, is there a way that I can determine which picture box has been clicked?

Is there a way to determine is any control at all on a form has gotten focus? I know you can individually determine if a single control has focus or has been clicked, etc. but is there an event that can tell you that some/any control has been clicked?
i.e.
Private Sub myFrm_Magic(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.SomethingClicked
Msgbox(Me.ActiveControl.Name)
End Sub

I want to detect when my touchpad is clicked! I normally use a usb mouse, so I don't use the touchpad for anything. Instead I'd like to make it possible to perform an action in .NET, when the touchpad is clicked. This way I can use it as a shortcut: One tap and something cool happens.
Is this possible, and if yes, any clue how? I'd prefer if it could be working in VB.NET or C#. My theory is that I'd have to make a mousehook, which then somehow determines which device the click is coming from. If the click is determined to be from the touchpad, then cancel the click and doWhatever().

Using 2 forms how would I click one button, from another form? ie In VB 4,5,6, I would used to do it as:-
Form 1:
private sub Command1_Click()
msgbox "Say Hello"
End Sub[code].....
If I clicked the button in form2, it would automaticlly, click the button in form1. Do I, do it the same way in VB Express or has it changed?

I have a TreeView with dynamically added nodes which I am using to actually contain textual data. I am using the tag field to contain special info for acting upon, based upon the node's tag. I have tried using treeview.SelectedNode.Tag. However, the selected node is the one most recently selected (like with a left mouse click), not the node I right-clicked. I have also tried using the contextmenustrip.SourceControl, but the source name for the control is always the container, the treeview control rather than the individual nodes. I have even tried associating my ContextMenuStrip dynamically to each individual node as it is added. The behavior is the same.A workable solution might be to cause a left-click when I do the right-click to bring up the context menu strip. I haven't been able to figure that one out yet either.

I have numerous buttons on a form, one each to select a playing card (52 buttons). When the Card(button) is selected I want to highlight it by changing the border from black to Red, then if reclicked from change back from red to black, easy enough (if then else). So that I do not have to copy this code 52 times I wanted to create a module as follows:
Sub ChangeButtonBorderColor(ByRef ButtonName)
If (Equals(ButtonName.BorderBrush, Brushes.Red)) Then
ButtonName.BorderBrush = Brushes.Black

I have already done the creation of button and the dragging of button at runtime already.But now i need to know how do i save the last dragged button on the form and also detect the name of the last clicked button.so lets say i now drag a button to coordinates 25,254. so when i exit the form and the next time i launch it, the button will still be at 25,254. and this one will go on for the number of button i created like 100. so when i launch the form the 100 button will be at the exact position where i last saved them.the second part is lets say i created button1 and button2 on the form in runtime. so when i clicked the first button, it should display button1. and if i clicked on button 2, it should say button2. same goes for like 100buttons.

Let's say I have a PictureBox with an image of a house, for example, and I want to know if the user clicked on the roof, the door, the window, or the walls.
Is there some way to, maybe, set up an If statement so that it checks what the coordinates of the mouse click was and compares it to a set of pre-determined graphed points to decide what object was clicked?[code]....

I want a context menu strip to have 4 specific items. For testing purposes, we call them Item1, Item2, Item3, and Item4.I've set up a context menu strip like this, and I am using it for about 20 different controls. I want these four items to do different things based on what control the user right clicks. The only way I could think of doing this, was to make 20 context menu strips and create a click event for each item. This obviously, seems like a really bad way of doing it.Does anyone have any suggestions or another way of making the click events for the individual Items based on what control is right clicked?

I have an old system developed in Visual Basic. How can I determine what Visual Studio version to use based on the source code files? I've tried to upgrade the application using VS2005, VS2008 and VS2010. With VS2005 when I attempt to upgrade the source, it says the system was developed in a newer version. I currently have VS2005 version 8.0.50727.42 installed.

the purpose of the program is to display the monthly payments on the loan.My homework is to use do while loops instead of for loop.Here is the code for the for loop.
Option Explicit On
Option Strict On
Option Infer Off

Now I'm having some trouble displaying the output using the do while loop, and I'm pretty sure it's a loop problem on my code. However, I cannot seemed to find out what's wrong. I looked at the examples of do while loop in my textbook, but I couldn't find anything useful to my problems of my program.This is the output for the do while loop.
Here's the do while loop code
