This is the code I use to open a file:
Quote:
Public filecode As String
Public Sub getfile(ByVal filename As String)
Dim objReader As StreamReader
But I keep getting the filenotfound exception.
I replaced the file source with the actual location of the file and got the same error. I also checked the permissions of the application to allow sharing and remove read only properties.
I have this rather unusual problem. I am creating a class library that requires information from a number of dll's. When I am loading the following, I am getting
Dim lexicalizedParser As String = "C:\dataStanfordParserwsjPCFG.txt"
Dim parser As Parsing.IParser = New Stanford.Parser(lexicalizedParser)

I've gone through about 16 hours and two packs of cigarettes trying to figure this out. First a little background. I was using 6.0 up until 2004 when I went to prison. I'm out now, and trying to relearn the trade, using VS 2005. I'm currently porting some 6.0 code from another project, SpyCast Webcam Studio, into VB 8.0. It's disheartening, to say the least. None of the old built-in subs/functions work anymore, so I have to scour the forums to relearn each and every function.The section I'm doing now takes a snapshot from the webcam (Video API --> PictureBox --> Save as Jpeg), then upens the file to upload it to the server via HTTP POST. I've been using this code in SpyCast for years with no trouble, but I spent many hours trying to piece together the right code to open the binary file to read its contents. I pieced together two methods I found around the forums, one using FileStream() though the code I found wasn't for binary files, even though it said it was, so that code doesn't really work. Method two uses Microsoft.VisualBasic.FileOpen() and works better.
Here's the kicker. By the time I run through the rest of the rigamarole of uploading the file, by the time I read it on the webserver, it's *slightly* corrupted. It's a valid Jpeg, no errors, but the picture looks like when I use to watch the Playboy Channel when I was a kid scrambled with weird colors and whatnot. [code] Each "chunk" is basically one "line" of the file. It looks like a single LineInput() return is the text between two carriage returns. Am I correct? I tested this with a flat text file, and it looks true. However, That one input line returns the text or data with the carriage returns *stripped*! ***?!? =( Fine, I have no problem adding my own vbCrLf to each LineInput(), if I were opening text. but this's binary. A character could be Chr(10) or Chr(13), both of which are removed from the original file contents.So I could very well need to use something other than LineInput(), but I haven't found any other examples on the web using this method.
I would like to find out how would it be possible to make a executable be lunched at the click of a button from a vb.net form.what I have so far is a form with a few button on.for example:
button 1 is called 'RegEdit'
button 2 is called 'system information'
[code].....
this complied will lunch regedit as instructed but what I would like to do is to put the console app .exe file into a root file of the application.I would like to be able to have, once this project is completed, a main folder with the name of the app and then a sub dir called 'resources'. the 'resources' folder would have the various command line .exe with instructions to open various system programs.
im making a program and it needs to load 95 files on form load.im trying to make it to if the file cant be found that it will give a error instead of a JIT debug thing. i triedadding

I'm making a tiny program that calculates a total for a user for some type of styling service. A user clicks the radio button for either hairstyle, perm makeup, makeover, or manicure. then clicks a discount radio button, either none, 10% or 20%. then it calculates the total (price of service - discount %). then it displays the total in the current service text box & keeps a running total and displays that in a second total box.
My problem is i try to run the program i made and it basically crashes. In the code, when in VB, there's an error message when you go over PriceDecimal, DiscountDecimal, and GrandTotalDecimal saying the variable is used before it is assigned a value.also is there any way to open a .exe file and see the code for it?

Im am trying to get two separate applications to communicate with one another via a txt file. The first application writes to a txt file every even second and the second application reads the text file every odd second. The problem is Im getting an exception saying The process cannot access the file FILE_PATH.txt' because it is being used by another process. Not sure if my code is correct or not? Or if there is a better way to do this?

One of the buttons is to save the the workbook by utilizing the users input as the file name. This workbook is to be saved as a template in a specified folder. The code also checks to see if the file already exists, and prompts the user to overwrite if it does already exist.The code I have seems to be working just fine. The problem is...when I try to open the newly saved workbook, it won't open.Here is the entire code for the button click event:

I'm letting my users write their own HTML from my webpage. When they click the preview button, my code behind needs access to controls on the page (and so I understand I can't use a web method here). It builds the HTML and saves it as a file on the server. My question is: Once the file has been made, I want to automatically open the file in a new window for the user to see their handy work. I'm using vb.net, but happy to receive c# answers.

In my project, I have a local dataset (XSD) that I am using as local-temporary tables. I am getting a System.InvalidCastException when trying to access the field in one the tables. I believe this is because I my code is (incorrectly) not setting a field's value in a row before trying to access it.My problem is that the exception is breaking in the designer file and not in my code. As a result, I'm having difficulting determining which line of my code reading the field value before it has been set. Is there any way to configure Visual Studio to break in my code instead of in the designer created file?

I am taking an Intro to Visual Basic class right now. When we do homework, we have to take it into class and put it into a folder that our professor has.When I save it onto my hard drive and I open it from Documents/Visual Studio 2010/Projects/HW Assignment 1, it opens everything perfectly. But on my flash drive, I have the same set up (E:/Homework Assignment 1) and I am not missing any files. But when I double click on the .sln file, it just seems to open the program without my project (display or code) showing.

My question is a rather simple one and to be honest with you, I am not sure if it can be done. Lets say I have a mutli-line text box, is it possible, and if so how would I go about making it so if I clicked Open with > editor I could do things with this text, such as TextBox.text = [file contents]. If it's not possible just let me know and I'll stick with open file dialogs.
