I started making a game in VB.NET, but I am stuck on the pathfinder. There are round objects. I want to know how to find a path get one object from one point to another (or at least as close as possible) without any collisions.
View 2 RepliesOk, so I have a webbrowser that loads a flash page, and there is some text there, which I want to compare to another image.
I have checked for server communication and there is none when you press the button.
So I want to know if it's possible to (A) Find an image on the web browser (B) Find RGBs of (x,y)s on the screen and compare them to their values?
I have written an application that calls 'My.Computer.FileSystem.SpecialDirectories.Currentm UserApplicationData'. My application is working fine, but one user has reported an issue that has me stumped. When this property is accessed, the following exception is thrown:
"Unable to find an entry point named 'VerLanguageName' in DLL 'version.dll'". The stack trace says that the exception came from Microsoft.Win32.UnsafeNativeMethods.VerLanguageNam e(Int32 langID, StringBuilder lpBuffer, Int32 nSize)
I don't think the problem is with my code. I suspect that there is something wrong with a system-level component on her computer, particularly with the DLL that is mentioned. Is this DLL part of a specific windows component that could be reinstalled/repaired?

I want to make my own xml-serializer class because I need other formatting than the System.Xml.Serialization.XmlSerializer does. My idea is to treat properties of primitive type (such as Integer, Double, String) as XmlAttributes.To properly implement a usable Xml-Serialization I need to know which variables point to the same object (the binary serialization behaves this way). Because one object should be serialized only once in order that the connections don't get lost.On the side of XmlSerialisation I have the idea to insert a path to the class as a special XmlAttribute.

View 1 RepliesI am suing VB 2008 express edition.
I am trying to solve this problem since many days. The problem seems to be rather mathematical, but I faced difficulties dealing with Grids and how to store them using visual basic.
[URL]
In my problem, I have a world of 200 x 200 units divided into 4 x 4 grids (Each of 50 units).
There is a line crosses some areas has the coordinates of Point A (Starting Point) of (XA = 12.43, BA = 159.48) and Point B coordinates (Ending Point) of (XB = 112.95, YB = 20.95).
The question is, how can find the length of (A to C1), (C1 to C2), (C2 to C3), (C3 to C4), (C4 to C5) and finally (C5 to B)?
In addition, how can I indicate the square in which the line is inside?
note that the method should work for all conditions (-ve and +ve line slopes) and for different A and coordinates.

I seem to have a problem with my DLL Function call test. I don't usally use orums...but...this is racking my brains and I need to know fast! I have searched and searched google, but I have no answer, (I do, but don't understand very well).I have created an application called epsControl.exe in Windowssystem32 folder. I have also created a file called epsDevDrv.dll or EPS Device Driver. It doesn't really act as a device driver, I just gave it a fancy name, (that's why I'm called the VB Weirdo.........) anyway to the point:My dll does a simple function, to answer a mathematical problem (simple), and return it to the exe file which puts it in a msgbox.

Now This is my first post and i am very inexperienced with Visual basic As an extra feature to a kiosk that i am making as an assignment in my year 10 ist class, (were doing it in power point 2010)
i am making a visual basic keyboard in Power point from swish max objects inserted through visual basic toolbox, i have found code to make a button that can type in to a text box once clicked. But i need code that when you click an object it types a letter into a visual basic textbox that i inserted into the power point prestation
I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

I have an Access database ubicated in the path: C:Documents and Settings obertoMy DocumentsVisual Studio 2008ProjectsDictionaryDictionaryDictionary.mdb But when I execute the instrucction: stringConnection=System.IO.Path.Combine Application.StartupPath, "Dictionary.mdb") the path where catches the database is : C:Documents and Settings obertoMy DocumentsVisual Studio 2008ProjectsDictionaryDictionaryinDebugDictionary.mdb
That`s is the reason why I am astonished because the insertions and updates in the database are made in this last path. Why having the database path in other path which isnīt inDebug works with this last?
There is a field in the database whose value is the StoredProc name with full path.for example test01.test.dbo.spGetData
test01 is the server name
test is the database
spgetdata is the SP
I am storing this in a variable
Session("GetSP") = objReader(1).ToString() (test01.test.dbo.spGetData)
Dim Command As New Data.SqlClient.SqlCommand(Session("GetSP"), conn)
Command.CommandType = CommandType.StoredProcedure
I always get an error cannot find the SP and it shows like this test.dbo.spGetData It is cutting of the servername test01 always.how can i get the full path.
Im looking for a way that if the program detect that for exemple the path "C:" is "true" then it will add , for exemple , "Hard Drive" in the checkedlistbox.

View 1 RepliesI'm need of some way of finding the UNC Path of a share via a script or command line or even a custom created program. I'm trying to automate deletion of users and the setup is a bit complicated.
Home folders are set up like this:
We create a folder on a Disk on a fileserver.When this folder is created, a share is automatically created on a lower levelThen the DFS Links are set up towards the newly created share.
Now, when deleting a user, I could just delete the DFS Folder, meaning that the target folder is the one being deleted. But since it's a share, that cannot happen.
