Best Application - Retrieve The Onset Of The Dive, Onset Of The Bottom Phase, Length Of Dive?
Feb 5, 2010
I am a biologist and I have a collection of dive data. It is very simple data...just time and depth (m). However, from each data set, I need to retrieve the onset of the dive, onset of the bottom phase, length of dive, etc. For years I have been finding these points through visual inspection of the data. It is extremely tedious and in know way efficient. I am interested in expediting this whole process and am more than willing to learn VB...but only IF it is the best approach for this application.I have attached two dives worth of data, so we can see what the data looks like. Each data set can contain from 1 to 8 hours worth of data.

In earlier editions of visual basic I could move the form across the page by changing left in the properties window. VB 9.0 doesnt have that in the window properties window. I can set start position to manual but it wont drag and drop how do I move a form window in the design mode? added by TNT 1/24/09 I went back and checked VB5 the left and top positions were settable but only located the form during run time.

My page has a drop down whose values are dynamically populated. Based on which item is selected, a number of TextBoxes are dynamically created during runtime.The user then fills in information into the textboxes and clicks a submit button.After postback from the submit button, I need to again dynamically create the TextBoxes during Page_Init (BEFORE LoadViewState) so that after the ViewState loads, my Button_Click event can save/do whatever with the user input. PROBLEM is, I cannot recreate the textboxes based on the selection in the dropdown, because the dropdown hasn't been "selected" yet by LoadViewState.SO, how can I read from the view state, create my textboxes, then let the viewstate populate the textboxes, and then the Button_Click will use the values??The one thing I've attempted is to override the LoadViewState function so that I can read from the view state, create the boxes, and then load the viewstate again. This did NOT work, because the debugger never seemed to hit my overridden function.[code]

I found some great code on capturing webcam images but the problem is the client PC will need to initiate the communication to this server (click Connect to server IP). This is like 2 way communication.How can i do something like this (door Kiosk system):when a visitor press a button on the LCD that come along a web cam (this will be the server), it will send the signal the client PC that is installed with the application i've created (window form) and pop up the images to the client PC (more like a 1 way communication). This image is captured through the web cam on the server to capture the visotor's image waiting outside of the door. How to do this?I'm really stuck as i'm not familiar with window API programming yet.
1) how to do the mentioned 1 way communication? possible in .NET?
2) how to make my application to be at the tray icon just next to the time displayed on the right bottom corner of the task bar? When a visitor press a button o the server, it will pop up a window form on the client PC showing the image captured via the server's webcam outside of the door.

I am in need of a small application, that will allways be topmost and will send keystrokes to the last active application (typically notepad or an explorer window). My problem is retrieving the current active form (or application), when my application is started up. Every search seems to return old and rather complex solutions using Win32 library functions, but I was kinda hoping, that .Net allowed for a neater and more simple solution.I need a code example or link on how to retrieve the currently active application window from another application just starting up.

I have a field displaying on a datagrid that the user has asked to be variable length based on the data that is returned. Is there an easy way to determine how many characters are returned for a field and then converting that to a pixel length so that I can change the length of the field in the code.

If using the following in an if statement I get an error: If trg.Name.Substring(4, 6).ToUpper <> ("ABCDEF") Then I get the error: "Index and length must refer to a location within the string. Parameter name: length"
I assume this is because the string (trg.name) is too small for the 4, 6 substring. What would be the correct method of working around this problem? VB.net Studio 2008.

I need to retrieve the actual text of a message box from another application. When using WM_GETTEXT, the values returned are the title of the message box, and the text of the control button (in this case "OK").
My issue is that what I really need is the actual text message from the box itself. I've been researching this for days and can't find a way to do this. Nothing I have found so far tells me how to do this.

I'm using VB.NET in Visual Studio 2008 in a Vista 64-bit OS. I'm trying to find an easy way (there must be one) to quickly retrieve from the registry the application file name and path to use in a Shell command to open a particular file. Specifically, I want the user in my app to be able to click on a PDF file and have the app open that PDF file using the application associated with PDF file types - Acrobat Reader, for example. Anyone have any suggestions as to proper coding & syntax for the following sequence?:
(1) Get name of .exe file associated with .pdf file type (most likely from the HKey Root Classes hive)
(2) Get path for the .exe file
(3) Shell("[pathname]appname.exe filename.pdf")
I've spent a couple of hours looking through the forums and haven't found what I'm looking for.

I have a TreeView in my form that I populate manually from a list of items in a database. The descriptions of the TreeView items causes a horizontal scrollbar to be displayed. That is fine except that it seems that this scrollbar hides the item at the bottom of the TreeView. If I expand a tree node the bottom item that was previously hidden will be displayed.

Is there a way to check if a RichText box is on the bottom? I don't think this is working:
Code:
If RichTextBox1.Selected = Len(RichTextBox1.Text)
'It's on the bottom
End If
What I am doing is, having the text go to the bottom (like a chat client) with this code:
Code:
RichTextBox1.SelectionStart = Len(RichTextBox1.Text)
RichTextBox1.ScrollToCaret()
However, if the user is looking at what was sent before, it scrolls them back to the bottom.
