I'm currently developing a little hobby project to display health information in a game on my G15 keyboard through VB.NET. When I use ReadProcessMemory via an API call, it keeps returning zero. The MSDN documentation referred me to use the Marshal.GetLastWin32Error() call to find out what is wrong and it returns 1400: INVALID WINDOW HANDLE.
I am now confused about whether the first argument of the function wants a window handle or a process id. Regardless, I have tried both with FindWindow and hardcoding the process id while the application is running (getting it from task manager). I have tried three different games, Urban Terror, Grand Theft Auto: SA and 3D pinball for windows, getting the memory addresses from an application called Cheat Engine; they all seem to fail. [Code]

I am using the tutorial laid out here http://www.androidsnippets.com/vbnet-server-side-code-to-send-c2dm-messages to attempt to send a message to my device. I have requested a device ID and placed that string in the RegID String.I receive a (what looks like a) GUID for the googleAuthToken successfully, but when the rest of the code executes,the response I get is Error= MissingRegistration. What exactly am I missing to implement C2DM from a server via VB.NET?

By the way what i want to achieve is how to get the data as a List(Of String),because if i put the getMenu function into the presentation layer directly,it gives me the data as i expected..Also if i return as a string instead of List(Of String),it gives me the single data.

My brain may just be fried since it's the end of the semester, but my teacher kicked this back to fix and resubmit...she said that I am "returning the name of your function rather than your variable name".
Here is my code for all 3 forms.

It checks if the webpage in the web browser control has crashed. The website crashes alot. I want to acomplish this by checking the text of the webpage for vital keywords such as "ERROR" or "Could not connect:" or "An error occured. Returning to the autowatch system in 60 seconds..." The code I have so far is below.
Dim myText As String = Me.WebBrowser1.Document.Body.InnerText
If myText.Trim().StartsWith("Could not connect:") Then
WebBrowser1.Navigate("http://www.enhanceviews.net/view/config_check.php")[code]....
The page refreshes every 5 to 120 seconds. The timer gets activated 10 seconds into the program's launch. It refeshes the code above every 5 seconds(to minimize CPU usage). However, it crashes and gives the error "NullReferenceException was unhandled". This could be because the page keeps on refreshing or the page is php and has 2 iframes. How do I fix this?
So I have a pretty simple UDF written in visual basic for use in excel. It calculates your approx. taxes. Lets say I use it as such: =Taxes(I23-I18,I24-I20,"Married")
If I type this in it works great. Now if I save the sheet and restart excel the cell now says #VALUE! If I select the formula and hit enter once again it recalculates it fine. What am I doing wrong? Application.Volatile shouldn't be needed but I was trying ideas. [Code]
This might seem like an insanely easy question, but I cant seem to find an answer anywhere to it.

I have a piece of code that checks a time and then adds hours based on the daylight savings time value.
Dim CommentDateTime as Date = "11/2/2010 8:21:42 PM"
If CommentDateTime.IsDaylightSavingTime Then
'do something
Else
'do something else
End If
The problem that I'm having is that IsDaylightSavingTime behaves differently on the production server than it does on the development.On the development server the case is TRUE, but on the production it is false.
Both servers are running the same OS and are both running .NET 3.5

I have an XML file that sits on the hard drive of a Server running my Web Service. I need to access that file from another application.
This is my method on my Web Service
Public Function getXMLFile()
Dim xmlDocument As System.Xml.XmlDocument
xmlDocument = New System.Xml.XmlDocument()
[Code]....
This is caused when I try to return the xmlDocument object
From the information I gathered, it's like SOAP wants to wrap my XML in more XML and stops me from doing that.
How do I go about getting the XML File from my Web Service if I can't return XML?

View 2 RepliesThanks William, that was the ticket. Had to assign the name property on both ends [DataTable.TableName].
On a side note here: There appears to be some school of thought (no offense Marc) that the following statement is always true:
"Everything in the world can and should be made into an object."
It is, simply, not always true. There are cases where you cannot cram your 'object' into any cookie-cutter or class no matter how you try to customize it. For me to objectize this beast, I'd have to create roughly 4,000 objects. I don't have time to do that, and yet this project must run as a service. Frankly I think the developers at MickeySoft need to get out more into the real world, and see for themselves that although theory is great it does not represent true-life challenges. I am all for working with objects for the obvious benefits, but there is a reality that universals do not exist. In my trade, even 'most of the time' rarely happens.
Before they push out a new technology set, and cease support of an old one, they need to make sure that the new technology has the same capabilities the old one had.
For the record: The people who believe the above statement to be true are also the same people who would refuse to take the project I'm currently working on.
Just the same -- thank you both for your time, efforts and opinions!
I'm trying to create a WCF function that will return a table to my console testing app. I am a total noob. The data is 2-dimensional and looks like this:
23 Letter
42 Another Letter
43 Document

...Of course, it won't work. I just need to get the WCF to pass a basic table to my console application. The execute SQL seems to work just fine, I just can't get the data back to my application.
returning a function value? I have a simple function that returns an integer. This function works fine when executed in SQL Developer but, when called from my apps, it always returns 2 regardless of anything. I have checked it over and over again, I cant seems to find where I am going wrong.

I want to return a value (vbCancel or vbOK) from a form which is shown as a dialog from the calling form.So, I overloaded the showdialog method to return the value.Trouble is, a value of zero is returned as soon as the form is shown.Now, if I can make it behave more like the showDialog method where execution doesn't continue until the form is hidden everything would be fine.

How can this be so difficult and why? Returning simple XML with no Name Spaces and an XML decaration. Creating the XML using XML Writer is easily done and if I output it to a file then great. How on earth can you return the contents via WCF. Using an XML Element is no good as you loose the XML declaration and using a string is no good as the output is wrapped up in a <string> element. Can't return an XML Document as it can't be serialised.I know that there are many posts on this site, but none answer the question. I am using VB.NET (boy I wish I had the time to learn C#) and I cannot get the Data Contract to work either even using IXmlSerializer. An example of the output I need to send back via WCF
