Detecting Items Under A Form - Pattern Matching?
Mar 26, 2009
Is there any way to detect the area under a form window. e.g I want to create a grid and use what's in that grid to match patterns.orIs there any way to take a screenshot of the area under a form?
I have been searching all over for something that will do this and the only thing I managed to find was [URL]..I do not however want it for this application (If I really wanted to cheat at a game I would buy the software). But this is a perfect example of the pattern matching I wish to achieve.Edit: OK scratch that... I have managed to take a csreenshot of the region under a form, now has anyone any experience in pattern matching images?

I have the same intention as in this question:
Automatically call all functions matching a certain pattern in python
But I needed the solution (if technically possible) in VB.NET. Is that possible in VB.NET ?

I need an extremely simple regex pattern that matches anything within square brackets [].
Example:
This is a [test] text with [some] [examples].Required results: [test], [some], [examples].I don't want to get rid of the brackets, they should be included in the result (that should make it easier, right?)
If possible I'd like to exlude results that have whitespace in them, so things like [this string] should not be matched. If that gets too hard (probably not, but hey I can't even manage this :S) then I don't really mind, I can always check if the result contains whitespace myself.
I tried a lot of examples I could find online and ones that I could think of myself but none work. Note: I've been testing with the Visual Studio Find dialog (checking to use regular expressions obviously), maybe that's where the problem lies, because I don't really understand why some of these don't work...
Anyway, first thing I tried was simple: match the two brackets and one or more characters in between (that should be a +, right?)

I have ListView with records (2 columns), I have also TextBox. I want when i type something in the textbox and if there is a match to select me that row of the ListView and if there isnt a match there will be MsgBox. I`ve succeeded to do it with 1st column. But if i try to use records from 2nd column it doesnt happen anything. Here is the code for TextBox_TextChanged that is working with 1 column records.
Dim boolFound As Boolean
Dim i As Integer
Dim intLen As Integer

I have a combo box with a list of Coordinator IDs, one Coordinator can run many subjects. On another form I have a list box that contains a list of the subjects, and another list box that has the coordinator that teaches the subject. The positions match up, i.e if there is a match for the co-ordinator ID in the list box at position 3, I want to extract the subject list box at position 3 also. The problem is 1 coordinator can teach more than 1 subject. Basically I want to show the subjects taught by the Coordinator the user selects in the combo box. I have tried the following but have had no luck:

In a project I'm working on, I have 3 separate mazes, a Splash Screen, and a Module for my global variable(gWin, to detect wins on the mazes). When you finish a maze, I'd like to get it so that it does not allow you to go back and redo a maze, to prevent cheating as I want a final screen to appear when they complete all 3 of the mazes. Is there a way that I can make a variable or something to be able to check if a maze was already completed then cause that maze to have it's .Enabled property set to false?

I am creating a user control where when a user clicks a button a popup window will show up with information. The popup window is driven by a toolStripDropDown so when it shows up it does 2 things
Does not move the other controls on the form around but displays over them That it can show the details outside the bounds of the user control itself without having to reserve the space ahead of time
Here is some code
Public Class Popup
Private treeViewHost As ToolStripControlHost
Private Shadows dropDown As ToolStripDropDown
[Code].....
Now my issue is as the form moves or resizes the Tooldropdown does not move relative. I understand that. When I try to capture the move event of the user control that event does not fire when the entire form moves. There has to be something I can capture because the controls in the container of the form move relative, what drives that? I tried wndproc but nothing fires during form move unless the form is repainted.

I made a form with text boxes in a 6x6 square pattern. It will do a streamreader from a text file a number that indicates the size of the array. Then fill in the boxes with the numbers of the array. Then it will calculate the rows and columns to see if they add up to a single answer. Then it will display to an output window if it is a magic square or not. Meaning if all rows and columns add up to a single number its magic. If they dont add up to the same number then its not magic. Then it will repeat this check and output from the information of the other arrays from the text file.
I know how to code for the streamreader and get it to add the rows and columns. Im not sure about what code I need so it can check the answer if its magic or not and repeat it till the end.
Here are the contents of my text file which it will read from.

I have two issues. The first is that I want to make a textbox scrolling similar to how credits scroll. I don't want it to move on the form, just to scrolling the text down a line/pixel. I thought I could do it with the "Lines" element, but I'm not exactly sure how to execute it.
The other problem is with my flash screen. Right now I have it set so when a button is click, it goes onto the main form. I don't want to use the button but rather have it so if Enter is pressed at any time, it'll go to the main form. All the solutions I've tried to use involve the "e.Keycode" code, but for some reason its unavailable.

My Request.Form keys are all prefixed with ctl00$container name$ and then the key I want.How can I get the regular key name working?
Visual example from the immediate window:I want to use:
? request.Form.Item("stationIdea")
but it won't work because the key is:
ctl00$content_innovation_body$stationIdea
as retrieved by
? request.Form.Keys("4")
so only this works:
? request.Form("ctl00$content_innovation_body$stationIdea")

How can you add items to a listbox on a form? Also this needs to be included so if another item is added by user it will be added directly to database.
Reason i am asking that is my project has to work in cojunction with Oracle Plus.
So far if i remember it is something like
.Add("Horror")
.Add("Romance")
I'm unsure if that is correct but i want the items to appear so the user can select one from list.
I think you have to include a data reader but don't mind that i can handle that. All i want is to add items to listbox when form loads.

I have two forms with one listbox on each form. How can I show what I have in the listbox on form1 on form2. I have a button on form1 to go to form2.
Private Sub btnform2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnform2.Click
Form2.Show()
Dim sTemp As String = TextBox1.Text & ":" & textbox2.Text & ":" & textbox3.Text & ":" & textbox4.Text & ":" & textbox5.Text
Form2.ListBoxFonts.Items.Add(sTemp) 'add to the listbox
End Sub
But when I click the button it goes to the form2 but it only shows one list and nothing else. When I go to form1 to add another list, it comes up with the listbox on form2 with two list, but when I go to my form2, it only shows the latest one I put in, it never shows two or more list, its probably just one line of code.

I was wondering how to drag items in a form, such as a picturebox. I know how to get it to follow the mouse when you click on it but I was wondering if there is any mouse down function, so it will only drag when the button is pushed down then it will let go when the button is released.
