G-Sensor/Accelerometer, How To Find Values
May 3, 2009
I have been searching everywhere to figure out how to access the G-Sensor/Accelerometer in my HTC Touch Pro and other like devices. I've already created a number of app's for windows mobile but now I'd like to add some more customizations into my app's. I don't mind installing 3rd party app's but I'd like to add the same fuctionality into my own apps with regaurds to the G-Sensor/Accelerometer funtions. I got a hold of some code(Rhaakmeester)...
[code]...
This code helped a bit but only detects the change after a 3rd party app has already changed the screen orientation or if the KB was slid out. How do I access the G-Sensor data myself.

I'm doing a project using VB 2005 Images of the application simulates using an accelermoet. However, right now, i need to create 4 buttons to simulate the diagonal position of the image.Right now, the accelerometer can move the image in 4 directions (mainly left, right , Up, Down).The 4 buttons mention, is in diagonal position( 45 degree Leftup, 45 degree Leftdown, 45 degreeRightu, 45 degree RightUp, 45 degree RightDown).I need to do it the way in which when my image is moved using the accelerometer, and once when i hit any of the 4 buttons, the image move accordingly. And when i use the accelerometer again to simulate, it also move.[code]

I am using Visual Basic express edition 2008.I am trying to know if a value in a single dimensional array is repeated in the array. If yes, then multiply one of them by 100. For example:
MyArray (14) = 12, 15, 18, 15, 18, 11, 15, 18, 16, 14, 18, 8, 12, 17, 10
In the above example:
MyArray (1) = MyArray (3) = MyArray (6) = 15
MyArray (2) = MyArray (4) = MyArray (7) = MyArray (10) = 18
MyArray (0) = MyArray (12) = 12

I am looking to create a VB 2008 Express programme which converts a data stream from a picoscope muscle sensor into a power output board which controls a mechanism.
In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.[code]...

I'm trying to get my hands on my ThinkPad T500 tilt sensor data.So the (unfinished, but works (i'll get three values, state,x and y)) code is:
Public Class Form1
Private Structure AccelData
Dim stat As Integer
Dim x As Short
[code]....
With debug.print I'll get the correct information, but as soon as I try to insert the outcomes to label.text I'll get error:
Attempted to read or write protected memory. This is often an indication that other memory is corrupt.
So, how can I pull the information from dll to label text?how to use the sensor.dll to extract information?

I am using Telnet in VB to read a temperature and RH sensor. I don't know that the data is the exact same length every time. I have pasted the code below. This code does get the data back. I have also pasted the unparsed and parsed data as well.... Sometimes I get more or less data than the time before and I think this is because I am not reading the entire buffer. How can I make this code run a little better so that I can get the proper data every time? Below the code is a sample of several readings. You can see how I get bad data periodically.
Unparsed
" 24.4155 45.2235 11.7921 200.9005 45.2372 45.2235 -42.0242"
Parsed (replaced " " with , and then " " with ,)

In simple terms when the Muscle sensor reaches a value of 0.8 V or higher I want the programme to send a text file to the power output control programme, and likewise when the sensor is below 0.2 V I want the power to be zero.
So 0.8 V > = send text file (0O=100%)
0.2 V < = send text file (0O=0%)
so when muscles being senced move the device turns on and off. I think I am successfully getting the data stream from the Picoscope which is plugged in the usb. I am using codes and examples that the programming guide for the device provided. [Code] I just need to now how to get the data to be displayed or how to tell the programme to do something with the data. The device also came with an example of how it can record data to an excel sheet if anyone needs the code to gain a better understanding.

I'm building a program to read a text file and display and find the min and max values within the textfile and display them in text boxes (txtMac, TxtMin) for the user. The program also needs to count the number of items in the text file and put the number in a textbox called count.
So far i've made the code to find the max value (below) but have no idea how to get min value and count.

I need to find rows in resultsets that have every column without null.these resultsets got variable number of columns.currently, the only way that I can think of is creating a view on each resultset and filter this way:
select field1, field2, field3, field4, ...
from "huge query"
where field1 is not null and
field2 is not null and
[code]....
and then in a storeproc/function or .net code(c# / vb.net) loop through all rows / columns and flag or remove every row that got any null?

Is there a way in LINQ to Entities (SQL) to identify all records where a specified word is repeated at least/less than a specified number of times?
I can do this in memory, looking for at least 3 instances of the word "word" using:
Where(Function(x) x.Description.Split("word").Count > 3)
However the Split() function cannot translate to a SQL equivalent, and so this can only be executed in-memory, which is excruciatingly slow by the time any number of records are involved.
The SQL to do this would be something like
WHERE Description LIKE '%word%word%word%'
And that's as far as I get - I can't work out how to get that SQL generated by LINQ to Entities. I tried the ugly hacky .Where(Function(x) x.Description.Contains("word%word%word") on the off chance, but I'm almost relieved that it doesn't work!

I need to know the IOCTL constants for the various strings (for example the value of the constant of IOCTL_ATA_PASS_THROUGH). Searching the net I found that those constants are defined in the header Ntddscsi.h but those constant are wrong. For example the constant value of IOCTL_ATA_PASS_THROUGH should be 4D02C while in the header file it is 40B
The question is: where can I find a list with ALL the right values?
I've found [URL].. where there are listed all the codes. the value in Ntddscsi.h is not the "final" value

Find common values in multiple arrays with PHP Pretty much does what I need, but in PHP, I need VB. My situation is I am trying to create an intelligent stock pick system based on multiple stock locations. At the point of invoicing, we loop through the items invoiced and check the stock database for available stock.
If all items on the invoice are available to pick from stock location 1, then all should be picked from stock location 1... etc. If all most items are available from stock location 1 except one or two, then pick all stock from stock location 1 except for the exceptions which should be picked from the location with the highest available stock. Finding highest available stock is simple, but I can't work out how to analyse the stock availability from multiple locations and finding the common stock locations.

I have a table called tblComparison - this table has the following columns[code]...
Once the averages for each column are created it needs to save them to tblMonthlyComparison - again the column names in this table are the same so in the fldDate column the program needs to enter 31/12/2011. In fldAverage of this table what we do is take the average that we found above for each column then plus them together and divide them by 5.

Having a bit of trouble using the List.Find with a custom predicate i have a function that does this
[code]...
by doing it this way means i have to have a shared "currentKey" object in the class, and i know there has to be a way to pass in the values i'm interested in of CurrentKey (namely, keyname, and oldkey) ideally i'd like to call it by something like keys.Find(AddressOf FindByOldKeyAndName(Name,OldVal))however when i do this i get compiler errors.How do i call this method and pass in the values?

Basically, I have an array of data with about 1000-2000 data points that form a rough Poisson distribution. What I need to do is take the maximum value of the distribution (which I know), and find the leftmost and rightmost values that are, say, 70% of the maximum. (I don't really care what the value of these numbers are. I want to know what index position they are in.) I then want to find the centerpoint between these two indices, rounding if necessary, and return all three values (left, right, and center).
