I had an idea for an MSN (Windows Live Messenger) "addin" today, which I thought was a great project for me to try.Basically, I want people to be able to type LaTeX code in their MSN conversations, and my application parses the LaTeX code and displays (probably in a separate window, but if possible inside the conversion window) the math formula.
I am probably not going to get it to send the image in the conversion window, but I will be happy if I can get it to display in a separate window.Basically, all I need for this to work is to capture the text that a user receives over MSN. If it contains a certain token (like "$$ ... $$") then I can try to parse the text between the dollar signs, and if it is valid LaTeX I can show an image of the result in a separate window.
So, I probably don't even need an actual MSN plugin / addin, if I can just get the received text by some other means.
1. some basic Windows Live Messenger add-in programming examples / tutorials? I've never done this before, and have no clue how to do it... VB/C# are both fine.
2. how to retrieve the text that you receive using either an addin, or some sort of windows API ?
So I'm looking for either an addin, or, if possible, a completely separate application that basically monitors each and every window and sees if it's from MSN, and then retrieves the received text...

How can i capture my console real time output and store the information in a log file?
i know that i can write in the file when i write in the console window, there's got to be a better way... how can i capture the console's output stream?
I found that Console.OpenStandardOutput is a stream, but i can't read from it
Dim r As New StreamReader(Console.OpenStandardOutput)
MsgBox(r.ReadToEnd)
r.Close()
r = Nothing

I've got a simple tool written in VB in VS 2010 that has a series of command buttons which run Windows command files and the output is sent to a Rich textbox object on the main form (the comand files take awhile to run so I wanted the output to show up in the RTB as it was produced to show progress). All worked well until I made an update to the tool so that the series of buttons are no longer hard-coded, but created dynamically from information in the app.config file. To do this, I use a button

i am trying to find examples of getting data back from a stored procedure that has no parameters sent to it nor has any returned output parameter. Though it does display data.How can i get that from my code im using below?
Dim myCommandSQL As New SqlCommand
Dim myReaderSQL As SqlDataReader = Nothing
Dim intX As Integer = 0[code]....
The @return_value i just put there to see what would happen but i got nothing returned.

Here's a simple code snippet of a larger function as an example.
Using conn as New SqlConnection("conn string")
Using find as new SqlCommand("ExampleProc",conn)
Dim rParam as new SqlParameter("@RESULT",SqlDbType.Int)
[code]....
I know the Output parameter is returned after the SqlDataReader is closed. From what I think I know, the Using statement will call .Dispose on the SqlDataReader, so will that basically wipe out the Output parameter? If so, what is the best method to call a SqlDataReader that also contains Output parameters that closes and disposes everything correctly? Let me add that based on what I've read you only have access to the Output parameter using a SqlDataReader after you call .Close on the SqlDataReader.

I have a problem with a streamreader in visual basic 2008.I am updating a database from text files on an ftp server. The streamreader works fine until the file is more than 100,000 bytes long.It reads until it reaches this point and then just ends. No error message, it just reads to this point which happens to be 2 fields out of 6 in the database stream. My question is - does the streamreader have a limit? And if so what is a workaround?
Dim connString As String = "Data Source=" & pDataBase
conn = New SqlCeConnection(connString)
Dim strQuery As String = ""[code]......

I'm writing a program that basically loads an entire text file into a streamreader variable, then reads this variable line by line and parses and writes a line into a new text file. I'm VERY new and my knowledge is mostly self-taught, but I can't seem to get out of this one. It works for smaller files, but it appears to reach a limit in characters at some point because in a file of 900 lines, it stops writing about halfway through 800 and there are no errors, the program actually completes and the message box pops up.
There are a few things with this code I already know I should fix, such as creating the new text file name, it's messy, I just don't know how.
Private Sub btnProcess_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnProcess.Click

I do have a control that inherits from UserControl.As you should know, I dont receive the WM_KEYDOWN message for the VK_LEFT, VK_RIGHT, VK_UP and VK_DOWN (Arrow keys). They are processed by window Proc as being a TAB key and not dispatch to the WinProc of the control. Instead, The control receive the message WM_GETDLGCODE.
In C, to get them, I use " return DLGC_WANTARROWS; " when I receive this message to get these virtual key and prevent Window Proc to move the focus to another control.However, VB does not let me used "Return" from Winproc, So, how can I get these arrow keys to be dispatch to the control.

I'm using Microsoft Visual Basic 2008 Express Edition. I have a Folder Dialog Browser added in my form and I call it when the user presses a button. The folder path string is stored in a string variable and displayed as text in a text box. (maybe I should use a combo box)
My question is: If the user inputs by hand a non existent path, how do I return an error message, stop the file creation into the invalid path, and return to my main form?

ok here is my problem, im making a little app for school since our school blocks pretty much everything so here is my plan a student makes 2 gmail accounts one for school one at home.
in the program at school (client) they put a site request into a textbox and they hit send, the request is then sent to the home pc gmail account and another app on the other side downloads the full site that they have requested and then sends them an email back with an attachment of the complete website, it is then opened in a browser and they have the site, simple idea and it would be easy except.
my school blocks the smtp protocols in vb, even outlook cant use gmail accounts only the schools registered email, however, you can access gmail on the internet without any blockages and you can send and recieve on the gmail website.so how can i use a webbrowser control to log the user into there gmail account through a custom gui, and send a string like www.facebook.com to the home pc gmail account, and then use the web browser controll on the students laptop to recieve the response email through a web browser, is there some kind of gmail api i can use?

I created a simple user control and everything went fine.Then I created another of the same control (as a different project) from scratch (creating the controls in a different configuration; but pasting code from the previous one from a text file).As far as I know I did everything the same for creating a user controlCreate a Class Library project Then Project>Add New Item> User Control Then delete the initial class that was added automatically (usually named Class1.vb) Put all of my code and components into the user control class.However, when I wanted to run it in the debugger as I did in the previous project, I now get an error message:"A project with an Output Type of Class Library cannot be started directly."

No additional installation needed.The datastore needs to be on the local hard drive.I am using VB.Net for a desktop app running Windows XP through 7 so it needs to callable by that environment.It needs to replicatable. If I have four copies of my app running on the network, each local copy of the datastore needs to replicate with the others. As close to real time as possible.

I have a module which will be responsible for parsing CSV data received from different user via a website interface, and I have to parse that CSV. I was considering to use, TextFieldParser for it.
But before I could implement I was considering what shall be a better approach...
Generating MemoryStream from data received,
or initialising a StringReader from the same input string.

After researching all the possible ways of sending the output of my program to an email address, I have yet to settle on the most user friendly way to go about this.I have created a form for a property management company I work for. I would like to send the output to a designated email address by a click of a button.Now given that the average user that will be using this software may not be necessarily tech savvy, I would like to make it do this as simply as possible and that means not having to know the smtp. Also considering that the user may not be on their terminal when using this software, using outlook to send the output may not be the best way to go about this. I have tried adding a webbrowser control and sending the email via html but I am not sure if that is the most logical way to do this.

Forget fancy shmancy web stuff. I'm looking for a good .NET CLI argument processing utility, prefer open source code. This is for quick and dirty utilities that need robust and friendly command line argument handling.These are utilities with maybe a day of effort in them. Investing a few days writing good command line handling seems overkill but they really need it.Features I like in command line handlers. I'd be thrilled with any open source project that had 2 or 3 of the following.A consistent syntax, posix had a nice command line standard, but not necessarily posix.Ability to provide short names for agruments. E.g. "msbuild /t" == "msbuild /target".It supports good command line parsing then gets out of the way. I want some that my code uses, not something that imposes a pattern on my code e.g. I don't want to have to respond to the presence of an arg with an event, that type of thing. Seperation of concerns is good enough that it's logic can be unit tested. Oh - is it two much to ask for it to read attributes off a class properties (as in .NET configuration classes)? I like the config file overrides in msbuild. I can set properties in a build file, but override on the command line. Built in "show usage". WSF files (csript.exe) have this functionality. I'm not willing to write jscript to get the command line handling though.Not powershell. I can't find anyone in my company who can stand Powershell syntax.
