How do you provide an image to the program, so the program finds that image on the screen and tells its coordinates. So if I was to provide an image of the start button, the program would tell the coordinates like (2,1000) or something similar.

I am developing a software that would scan the image in a picturebox and obtain the rgb values of each pixel in the image and convert each rgb values to HSL values. I am using vb 2008 express edition. I am still a student. I am just starting to learn vb 2008. All I have done is to obtain the image in a file and paste it in the picturebox. Below is my code. I dont really know how to start with the process of obtaining the rgb values of each pixel and converting them to HSL values and averaging the HSL value.
Code to obtain image:
Option Strict Off
Option Explicit Off
Imports System.IO
Public Class Form1
Inherits System.Windows.Forms.Form
[Code] .....
I still do not know how to start with the process of obtaining the rgb value for each pixel.
I have written up troubleshooting documents for my project and would like them included in my program. I remember in VB6 there was a very easy way to do this with a control, where it already has the help document tree set up on the left and you just set it to point to certain files.
Does something like this exist for .NET? I am aware of the HelpProvider control but as far as I know this just puts in tooltips and opens documents on a button press?
Consider the following :
Dim Length1 As Double = (10* 12) + 5
Dim SqFt1 As Double = 0.0
Dim length2 As Double = Length1 / 12.0
Dim tape As Double = CType(210.0, Double)
'Length2 at this point has a value = 10.41666
SqFt1 = CType(length2 * tape, Double)

WinFormsApp Login passes information to .php (server based) Login (provided credentials are correct) to DB to retrieve Decryption Key. WinFormsApp then uses Decryption key on Hardcoded encrypted connection string and renders application usable.This would then eliminate the necessity to encrypt/decrypt a connection string at runtime, virtually rendering any unauthorized person with a useless software.

View 3 Repliessample_form.rtf (1.48MB). Number of downloads: 36. I have a working form to give specific choices to the user and retrieve the user's choice. (See code below and attached image in WordPad file.) I know I can use a global ("Public") variable to pass the text of the three choices from the calling form to the called form, but is there a way to pass these from one form to the other exclusively? Of course, my main objective is to have as little memory being used as possible. I would like to make the form in my example (frmDialogChoice) a generic form that can display any set of three choices.
code within calling form:
Dim intSwitchToMake As Integer
Dim insFrmDialogChoice As New frmDialogChoice
insFrmDialogChoice.ShowDialog()

View 4 RepliesWhat is the best way to go about retrieving data from a proprietary hardware device that interfaces via HID USB? The particular device I need the data from is a blood-pressure/heartbeat measurement & monitoring device.The hardware came with software that downloads the data from the device and places that data into a (passworded/encrypted) MS Access database that I cannot connect to using programmatic methods, at least not without having the (admin's) password. The software provided produces reports, but the formatting renders them virtually useless (well, completely useless) for the needs of our company.
The device manufacturer provides to it's customers no API or any other technical information for accessing the data produced by their product; so, this pretty much leaves me stuck trying to figure out how to obtain the data via custom application in order to reclaim the initial justification for the expense associated with the hardware, which by the way has already been purchased.I don't need code snippits specifically, though examples would be nice; what I really need is to know is how to best approach this project, from a general design and programming stand-point.
I want to be able to search the windows event log (security) on our 2008 DC to find out when a certain user logged in. Using the system.diagnostics.eventlog namespace I can search and view information based on the event Id(4624) but I cannot work out how to display the login name of the user.

I've been looking into a way to obtain Parent Processes and then list them in a TreeView so I can list the child processes as child nodes However, it doesn't look like the framework has any built in methods. I thought I heard something about MS putting it in the .NET Framework 4.0. But, that's irrelevant at the moment.
Since there are no specific methods, is there still some way I can manually retrieve this info? Or would have have to use some unmanaged code? Maybe an API?
There is Notepad opened.How can I display the full application name from the taskbar into label1.text.
For Example:

or

Can I check the applications if they contain the word "Notepad" and if they do then display the whole name in label1.text?
From what I'm finding, there doesn't appear to be any particular function available to obtain the value from a particular field from a double clicked on row of a datagrid...
So if you wanted to double click on a particular result in a datagrid, then pass one or more of the values of that row, you couldn't?
I was thinking something like this, but of course that doesn't work, any ideas?
Private Sub InventoryDataGridView_CellContentDoubleClick(ByVal sender As Object, ByVal e As System.Windows.Forms.DataGridViewCellEventArgs) Handles InventoryDataGridView.CellContentDoubleClick
Dim invID As String = InventoryDataGridView.CurrentRow(???ParticularField???)

I'm trying to obtain name/value pair of enumeration typed into text box with LINQ. It's OK with name, but when LINQ reaches values, it throws error: "Conversion from string "Black" to type 'Integer' is not valid". I have read that if I want to obtain a value, then I gotta use conversion function.
Here's code (button's Click event):

Is it possible using Reflection or some other method to obtain a reference to a specific class instance from the name of that class instance? For example the framework for the applications I develop heavily uses public class instances such as:
Public bMyreference as MyReference = new MyReference
Then throughout the application bMyReference is used by custom controls and code. One of the properties of the custom controls is the "FieldName" which references a Property in these class instances (bMyReference.MyField) as a string. What I would like to be able to do is analyze this string "bMyReference.MyField" and then refer back to the actual Instance/Property.
In VB6 I would use an EVAL or something simular to convert the string to an actual object but this obviously doesn't work in VB.net. What I'm picturing is something like this:
Dim FieldName as String = MyControl.FieldName ' sets FielName to bMyReference.MyField
Dim FieldObject() as String = FieldName.Split(".") ' Split into the Object / Property
Dim myInstance as Object = ......... ' Obtain a reference to the Instance and set as myInstance
Dim myProperty = myInstance.GetType().GetProperty(FieldObject(1))
I've been going round in circles with this for about 30 minutes.
