I have used Winsock to receive coordinate of the objects (displayed in (Rich) Text box). How can I get those data into Excel or anything to display on GIS mapinfo??
View 3 RepliesI am trying to build a coordinates system but am having trouble with how to.. What I have sofar is a textbox that allows the user to enter a length. This length is user defined but never smaller then 610 in length since this is the minimum unit size we use to build timber frames. The overall length of a timber frame is infinite (well not really, but it is for what I want) the timber frame has beams every 610mm set apart from each other (this is a legal requirement) so I want my vb.net to set coordinates for each beam at intervals of 610 then write that coordinates system to a text based *.SCR file

is there a way of getting the screen coordinates of individual cells on an open Excel sheet, what I want to ultimately do is pass in a cell range say, "A5" into a function and watch the mouse cursor move slowly to that cell. I know this might seem a weird request. I already have a mouse move function but that accepts the x/y coords in pixel terms where excel using .TOP and .LEFT give an entirely different format?
View 1 RepliesI'm struggling to think of a reason why I should be getting an 'Access denied' error when trying to save an Excel document opened through a program written in VB 2010 Express. The program is essentially glorified Excel automation. It converts information from hundreds of Excel documents into a few small text files in order to improve operation speed. The software is designed for use by no more than a dozen or so people in the office who are all editing these Excel documents (through the software), and saving changes. They edit a given document by selecting it in a list in the main form, which then changes the document to writeable and opens it for them. A FileSystemWatcher detects changes in the folder containing the Excel documents so that the aforementioned text files can be updated when the user saves the Excel document.

This program is being used to analyze an excel document with coordinates for a robot. The entire program works...My boss indicated he wanted me to throw an exception in whenever a coordinate that wasn't being given a tolerance wasn't supposed to move, he wanted the program to give an error message. Which I figured out and outputs a message box saying "Result Compare Fail!"
Now here is my dilemma..whenever I encounter a section in the excel sheet analyzing multiple variables, I still get the error message, because the program doesn't think of it as multiple variable coordinates changing. Is there an easy way to fix this? I'm stumped! This is one of the cases, but they are all very similar.

View 1 RepliesI am building a program which relies on getting info from a twitter user. My idea was, I could either: A. Search the twitter user's feed for the current time. Or B: Get a email notification when he tweets, and send a sound. If I go with I would need to know how to search a webpage, get the time, and ring a sound if the time is present. If I go with B, I would need to know how to check email, and play a sound if a new email is recieved. Which one should I go with, and how would I do the things that I would need to know?
View 1 RepliesAt the minute I can display the mouse position using Cusor.Position.ToString() but my screen resolution is widescreem - 1360:768. What about about someone with a standard 1024:768? If I use my application on other computers, it won't work because it deeply depends on mouse co-ordinates
I am aware of a world coordinate system (or something) that will work on all screen resolutions. To use this (which I will need to) I will need to change all of my coordinates in the code? So I'll need to display it in a text box like I did with Cusor.Position.ToString() but what code can I use to get the world coordinate?
There is something like PoibntToScreen and PointToClient but what do these do exactly and how do I use them? I tried using
Code:
MouseCoordinates_tssl.Text = "Mouse Coordinates: " + "{X:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).X.ToString + "; Y:" + PointToScreen(New Point(Cursor.Position.X, Cursor.Position.Y)).Y.ToString + ";}"
but much to my disappointment, it didn't work. What could I do that would work?
I have a problem related to a project work of field observations of points. So I have a text file (file.txt) of coordinates X and Y of vertexes (separated by a comma like below):
X, Y
12.2 , 13.1
15.4 , 19.3
13.6 , 12.5
(and so on to 15 lines of x's and y's)
I need a program which can read this text.txt file with the given coordinates and store them as 2 generic lists using Loop and Split function and also the program should display the data read from text.txt file into a multiline text box. Next the program has to use the 2 lists to be passed to a function that first calculates the average values for the coordinates X and Y, and then work out the areas of triangles by = 1/2 SUM [ (xb-xR)(ya-yR)-(yb-yR)(xa-xR) ] where x/y ''a'' is the current vertex and x/y ''b'' is the next vertex in the polygon. I presume the program has to loop around the whole polygon to vertices to summing up the areas of the triangles and at the end multiply by 1/2 and give the positive modulus or ABS() of the area.
Develop a Company Logo application that allows users to draw shapes. The application should provide the user with RadioButtons to allow the selection of the next shape to be drawn.

I have a Geo-tagged snapshot (photo) captured with a my digital cam.
I want to read world coordinates (real coordinates) upon click on any pixel on this photo.
I just wanted to confirm my reading -- this is the number of bytes that is put in the buffer before the data received event is triggered, correct? And it's ONLY for that purpose?

View 8 RepliesI cannot find a way to get the server to put the information of the recieved packet onto a textbox for the user to see.Client Side:
Imports System.Net.Sockets
Imports System.Text
Public Class Client
[code]....
I am also trying to get the server to send back a packet to the client saying it recieved the packet sent. I just dont know how to translate the packet to a textbox.
I took a look at System.Security.Cryptography.MD5 class about using a checksum for a UDP program i am making.Basically i want to use it, to ensure the server is receiving what the client sends it, in a way that the server can make note of it receiving properly without having the client keep track of how many proper payloads the server received. The reason i need a checksum is because the client is sending a random hex payload, so i cant have the server predict what it should receive the same way as i have it working with the sequence number.I dont fully understand how i could implement this to my code. I believe i should make a public property in my packet class, but im having trouble implementing it with the way i coded my program. [code]

Private Sub SerialPort_DataReceived(ByVal sender As System.Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) Handles SerialPort.DataReceived
Dim cnt2 As Byte
[code]....
For some packets I sent, "Error Data Received" came up. I checked BytesReceived, it was 0. My question is: since SerialPort_DataReceived processes data received, data was supposed to be received. Why the number of bytes I read was zero? BTW, when is this event accessed? it is accessed when any number of bytes received or the whole packet received?
i have an excel spread sheet of my movie list, along with a column of what each movies genre and a column for its length. I am writing a program to randomly pick a movie because I can never decide on what to watch.I have options in the program to pick genre and a length (eg 90-100 mins), which are hard coded in, and then a button to pick from the criteria. So I need the program to filter when a criteria is picked, for example if I pick Action I want the program to filter and leave only those movies with Action in the genre column. The same for length. Once these have been done, and I hit the button I want the program to select one of the remaining movies at random.

I've been trying to publish some software for 2 days. At first, I received an error about frontpage extensions not being installed so I installed them, only to screwup the ht.access file on my site and lose my web site for 5 hours.
I had an email this morning from Lunarpages saying they installed the extensions, recoded the ht.access and even tested frontpage on it. SO -- I tried again this morning and still received "the components for the frontpage extensions are not installed". ?
AND --I must be missing something and looked everywhere in VB.NET (options etc) but how in the heck can you publish something directly to your website (I used the wizard and setup all the publish options) and NOT be prompted for your user ID and password? Obviously, VB.NET has it's own ftp program.
