Get Text From Dynamic Drop-down Item?
Jun 18, 2010
My program populates a drop-down menu with items dynamically at runtime. The items listed are the currently running windows and applications seen in the Windows taskbar. I was wondering if there was a way to retrieve the text of a selected menu item during runtime and use it to set focus to that application or window (which is the text of the selected menu item). I have looked at using the AppActive function to achieve this. I just don't know how to retrieve the text of the dynamically created menu items. Please keep in mind that I am an amateur coder so my code might look stupid. I have tried the following code block with no success:
Private Sub AppActive(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles CurrentlyOpenedWindowsToolStripMenuItem.DropDownItemClicked
AppActivate((Me.CurrentlyOpenedWindowsToolStripMenuItem.DropDown.Items.Item(Text.ToString)))
End Sub
Should I be using the SetForeGroundWindow API instead?

I have an application which is using a set of three combo boxes. I have managed to populate each drop down depending on the selected value of the previous one The only problem is that, since the data is coming the database two selected values from the first combo box may have two different number of items in the database. so the second combobox should be populated with such data each time the selectedIndex_changed nethod of the first combobox is invoked
if for example, the first combo box's first item has 10 corresponding items in the second combo box and a first combo box's second item has three corresponding items in the second combo box, selecting the second item after selecting the first item will lead to second combobox showing the three items and seven empty entries trailing after the three.
What I want is to have the second combobox loaded with three items exactly when the second item in the first combo box has three items in the database
here is an example
Private Sub cboAccountGroup_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cboAccountGroup.SelectedIndexChanged
If mblnAccountGroupFirstLoad = True Then
Exit Sub

I'm using Visual Studio for the first time and VB. I have programed for awhile, but mostly new to windows related softwares. I have an access database connected to my test application and I am trying to display a drop down box with a listing of the item names in my table and the value that is sent off to my database is the actual item id. I can figure out the database part in terms of adding and editing, but I haven't been able to figure out how to display the full list. If I click the next button the list that is generated it displays the next item, but I would rather just list all items in the drop down box and remove that toolbar all together.

I'm trying to automate a form process from a previous employee. One of the things that I have to do to achieve this is select a COM port from a dynamically populated list. I've looked around and the closest thing I could come up with is something like:
.cbbCOMPorts.SelectedItem(1) =
True
While this compiles, the computer does not like this at run-time. It throws an exception out:
"Object variable or With block variable not set."

I have two (Telerik) TreeView controls, let's call them tvSource and tvDest. I want to drag/drop items from tvSource to tvDest. I have this somewhat working, but am experiencing two problems:
1) What it now does is moving the item. Instead I want them to be copied (from tvSource to tvDest), leaving the item in tvSource.
2) To allow items to be dragged from the tvSource control I have to enable DragDrop. With this enabled the user can drag/drop inside the tvSource control, which is not what I want. The items may only be dragged (copied) to an other control (tvDest).
Below is my code so far:
Private blnMouseIsDown As Boolean = False
Private Sub tvSource_MouseDown(sender As Object, e As System.Windows.Forms.MouseEventArgs) Handles tvSource.MouseDown

i seem to have a problem when i try to select a ComboBox item which is a drop down list. The ComboBox contains a list of various items where the user can select from a list, the type of query he/she would like to perform on an Access Database. Two of the items in the Drop Down List are "Employee Sales Between Specified Weeks" and the other item is "Employee Sales Between Specified Months" (without quotation). Now in my VB code, i have a really long If/ElseIf Statement which includes all the options the user can select. Additionally, if the user has selected a week query, he/she must select a From Week, a To Week and a Year (for example week 3 to week 5 year 2009). From Week is another combobox (1-53 weeks) and To Week is also another ComboBox (1-53).When the user selects a month query, he/she should select a From Month from a ComboBox (1-12) and a To Month from another ComboBox (1-12) and the year from the same Combobox (e.g 2009).

I am new to VB and what I would like is for the user to pick a item from the drop down box and from there; there would be a list that pops up to the side with that users pick list of attacks. I am trying to do this for every item in the drop down box. So, when the user changes character type it automatically changes the list to what the user picked. Below is two pictures one with the ?amazon? picked and the other with the ?sorceress? picked. To give you an example of what I am trying to do. My question is what the best way of doing this?

I have set the combo box dropdown style to dropdown, the auto complete mode to suggest append and the auto complete source to list items. This works fine IF I choose the required item using the mouse. If I type the full item name into the combo box, it is displayed but not selected for use. Is it possible to use a key such as TAB or Return to select the item in the combo box's display area after the drop down window has closed?

I've worked out how to create a DropDownList using the following code: <select id="salesPersonDropList" runat="server"></select> In my .aspx page, then my code behind loops through database output running:
Dim newListItem As ListItem
newListItem = New ListItem("Title", "Value")
salesPersonDropList.Items.Add(newListItem )
What I can't figure out is how to programatically set which of the List Items created is the one to be pre-selected in the rendered DropDownList, ie, how to create what I'd write in HTML as:

OK, I'm trying to display tooltip text for a dynamic edit box. Well, at least I'm trying to.
On my form, I've got a tool tip control which I've conveniently named ToolTip. My edit box displays OK. But, what I want to do is when the user hovers their mouse over the text box, I want the tool tip to display some text.
I think there are two problems that I'm having. I'm not convinced that I'm properly addressing a dynamic text box name. Ideally, I would want to be able to refer to the text box (but using a dynamic variable that will contain the prefix of the name). To hardcode, I would want to be able to achieve (not in this example but in theory): ABCDEFGt_0300.Text = "hello"
Dim controllerName as string = "ABCDEFG"
Dim t_0300 As New TextBox()
Me.Controls.Add(t_0300)

What Im trying to do is create a function that sees how many items Im wanting to add, then add each item to the combo box, without me having to add each item individually. Basically its to save space coding, and make my code easier to follow.
An example of what Ive got is:
Dim option_one As String = "Inches"
Dim option_two As String = "Feet"
Dim option_three As String = "cm"
Dim option_four As String = "mm"
[code]....
So the function would go instead of all those add items, and it would just say Call ItemFunction() or something like that.

I'm currently working on a program where I'm trying to dynamically create a picture box, a button, and a label for each item in a text file. Any ideas on how to do this? What I have: a plain text file with a list of numbers. Each number corresponds to a location. When that file is read, I want to create a picture box, a button, and a label related to each number. If I want to add something to the screen, all I Have to do is add a number to the file. So, lets say the file has. 1, 2
When the file loads, it will create a unique item on the display for each location. say pic1, button1, and label1 and pic2, button2, and label2. Right now, if I add something to the file, I have to go back into the editor and manually add everything. Which is a pain.

I am looking to include in my word processor a drop down font selection button, much like that in MSword, where it shows the installed fonts an allows the user to pick one. It is for a rtb, so I'm not sure if it's possible. If it isn't, could you guide me into coding a button with say the text 'Arial' to change the selected text in my rtb to arial. Also, which fonts are supported by rtbes?

I have a problem with Combo Boxes. When one uses the mouse to open the drop down menu, the text appears to be missing, but when you click on a entry, the text appears in the box at the top of the combo box (the thumb?). Likewise, when the cursor keys are used to scroll through the options, the text appears in the thumb.
