Selecting Oval By Name?
Feb 24, 2012
I have a series of ovals named "lamp1" through to "lamp26" and wish to change a particular lamp's backcolor.I have done this for labels (Controls("Label" & intButton).BackColor = Color.Black) but Controls does not work for Ovals. I assumed this was because Ovals are part of the PowerPack set but I cannot get any further.

I have a form with around 20 ovalshapes (the one that comes with Power Packs 3.0). I have named them p1, p2, p3, p4 and all the way up to p20. Is it possible to loop trough each shape in the form and check if the name contains a specified number? I'm thinking of something like this:
For Each ovalshape In Me
If ovalshape.name.contains("13") Then
ovalshape.backcolor = Color.Black
End If
Next

I am trying to add shape per user's selection...
if (chosen circle)
use microsoft powerpack ovalshape and all its properties
if (chosen rectangle)
use microsoft powerpack rectangleshape and all its properties
I have installed the Visual Basic PowerPacks V2.0. How do I add this powerpack component to my VB2005 code to use oval or rectangle shape properties?

I had created another thread asking how to create OvalShapes during runtime... Ok, so I have that covered, but what I need to know how to add properties to these OvalShapes individually. The OvalShapes are stored in the List(Of OvalShapes) if I create a loop from 0 to the length of the list it modifies all the OvalShapes with the same propertiesWhat I�m trying to do is make like 5-10 balls collide, this is why I need these properties to be individual to each OvalShape.

I am trying to get back a single from from a EF database model using the below line of code..
Dim _classRoom As classrm = db.classrms.Select(Function(b) b.Course_ID = _CurrCourse.course_ref)
Where classrm is the name of the entity and db is declared as a new entity. What I am trying to do is select a row from the entity based on matching Course_ID which in this model is a string. So that I can later use the variable _classRoom to get other items out of the same row.. However I am getting the following error:
Unable to cast object of type 'System.Data.Objects.ObjectQuery`1[System.Boolean]' to type 'Trial_Online.classrm'.
I have to preform similar tasks with several different Entities but if I get pointed in the right direction I can manage from there...

I have the following document[code]...
Now, how can I get the ID of the Div, by selecting text in his Field?
For example, if the user selects the text "Div1 - Text" (or part of him), the result should be "ID1".
if the user selects the text "Div2 - Text" (or part of him), the result should be "ID2", and so on.

Can anyone reccommend a good database that I can use on a local machine to storenames/addresses etc. and that integrates easily into .Net 2.0.I have used MySQL a fair bit, so something along that route would be great but without the need to install additional software on the computer or connect externally to a server

I wrote some software that use the AVICAP32.dll to do a spot of video capture.All was going well till they went and bought a laptop with a built in webcam.Now my software picks one a random and uses that for the video (somewhat annoying to say the least) Can anyone tell me how to pick a camera to use,I suspect it is related to DVM_DIALOG but my experiments have not been too successful.

I Have a problem with selecting a row in a datagridview. I want the user to press on the data rowheader of the data gridview of a particular row and then that rows first item are put in a string. But the problem is that if i Select an item another item is still selected. So If I press the mouse button on the row header the previous item is still selected and then the wrong data is in the string. Here is the code under the event of the datagridview mouse click:
Private Sub dataGridView1_MouseDown(ByVal sender As Object, ByVal e As MouseEventArgs) Handles DataGridView1.MouseDown
Dim hit As DataGridView.HitTestInfo = DataGridView1.HitTest(e.X, e.Y)
Dim index As Integer

I have a form that needs to add user selected items to a listbox. But these selections are done outside the form itself. So in windows explorer, the form pops up and then the user keeps clicking on files and I want these file names to be added to the listbox. How can I do this? in my case, as soon as I click outside, obviously the form loses focus. How can I "listen" to mous clicks outside?

I've data of 40 temperature sensors in a data table. I want to extract particular column from SQL from this data table, usually for this to occur One can Say write "Select value FROM table" where value is the parameter, this is ok, but it returns a value in specific row(s) of specific column whereas i want opposite. I want to my query to select particular column as argumument. I have 40 Columns.
Like: SELECT S1 FROM Table, SELECT S2 FROM Table .... but this is too hectic to write it for 40-50 sensors. Is there any way that i can replace S1-S2 in above statement as argument and provide it on runtime to select particular column?

I have a simple ASPX page with a listbox and a button. Listbox has about 8-10 items in it. After the user selects an item (listbox is multi-select) and clicks the button, I'm iterating through the items to get the selected one like so:
For Each Item As ListItem In lstLetters.Items
If Item.Selected Then
Dim LetterID As String[code]....
When I step through the code, I select the first item from the listbox. I setup a watch on the 'Item' variable. The code will iterate through each of the items -- but Item.Selected always reads 'False'.I double-check the page, and sure enough my item is selected on the form.What the heck is going on?

I have a datagridview that is bound to a dataview. I use a textbox to sort the list of data in the datagridview. Once the list is sorted I want to click on a row to populate the textboxes in order to update the data. Problem is once I sort the data I click on say row 3 and it pulls up the orginal data before the data was sorted in the datagrid view. For instance:
Before Sort:
1. betsy
2. james
3. john
After sort:
1. john
2. james
3. betsy
If I double click row 1 it will pull betsy info into my textboxes instead of john. I currently refresh my datagridview after every letter is entered into my textbox. I also reload my dataview and rebind the dataview with the datagridview.

I have a bound datagridview containing 4 columns. All I want to do is click on a row and then assign the value for each column to other controls (in this case textboxes). My problem is, I'm not sure which Event to use. I don't know how many events I've tried the code below in several different events but none of them are working.[code]
