create a text file then write "0" (zero) to it.It is for a larger project but this is the code that I have been working with:
Public Class Loading Dim Path As String = "C:NAME.txt" Private Sub FileCreate()
[code].....
It all seems to work fine until it tries to write "0" to the .txt file. It comes up with an error saying that the process cannot access the file because another process is using the that it just created! I have checked and the only process using it is the one above.
I am working on a project to use a stepper motor to pull film and then stop and take a photo of the frame. I have a stepper Bee controller and motor and everything works fine with there gui interface tool. Now what I am looking at is making a VB script that I can control the motor. They provide a dll file for the stepper controller and lots of doc data but is confusing to me since never used VB scripting. I have Visual Studio 10 installed and not sure if that is what i need. So here goes. It requires this at the beginning.
Declare Function InitStp Lib "stp.dll" () As Integer
Declare Function RunMotor1 Lib "stp.dll" ( ByVal steps As Integer, ByVal interval As Integer, ByVal direction As Integer,
[Code]....
Now the part I do not understand is I open a new project and select one of the many different FrameWork Applications. I no idea what to select. What I wish to end up with is an exe file that I can click on to start or run from a command line if needed. Here is a link to the site and scripting deal. [URL]
Right now I have a Email class that has all the properties of an email to send it, and then a SendEmail function which takes those properties and uses them in the following
Public Function SendEmail() 'Exception handling Try
[Code]....
The loop goes through each email in the array to process its email, however with the multithreaded function I cannot call
"EmailArray(i).ThreadSendBatchEmail()"
So how do I call an objects method when its on a different thread?
And I'm making it multithreaded so I can easily pause the process, and because the program freezes when the send() function is working, this would resolve that.
I am having trouble getting data from a text file to go into an array that I will make a parallel array for searching for data. I am not certain if it is how I state the while statement or how I stated the transfer to the array that is causing me problems. Here is my code.
Dim InfilePro As IO.StreamReader Dim InfileProNumber As IO.StreamReader Dim InfilePrice As IO.StreamReader
Basically i have a 500 line javascript file i made that runs in grease monkey (a add on for firefox ) I'm using vb.net to "compile" this script depending on certain check boxes.
So for example. (this is part of my script)
#RegionCapsEnforcer var array=document.evaluate("//*[contains(@class, 'postbody')]", document, null, 6, null);
[Code]....
and so on. So if chkCapsEnforcer was not checked it would skip that part and go to chkRevealUrl and if that was checked would get that bit. Then once it has gone through all the checkboxes it would write the enabled bits to a text file.
i'm having issues where I can't figure out how to take a text file that was provided for my homework assignment, and put the information within it into 3 different arrays.The .txt file looks like so:tc.Amanda/Ashley have to be in the same array as well as 4/2, 166/20.This is what I've come up with for the snippet of code, and so far, it hasn't really been working right.
Dim namearray(MaxItems), rankarray1990(MaxItems), rankarray2009(MaxItems) As String Dim Numitems As Integer Dim sr As System.IO.StreamReader
I have I text tab delimited file. in every line of that file at the same position in every row of the file I will have a bit that I would want to compare against 23 values (I will call them criteria). So if on every row the string I need matches one of tjhese values then that row will be written in File1.Txt if that value doesn`t match any of the criteria the whole row will be sent to File2.txt.
So far managed to get the original file written in the same format in a newly created file.
how to get the functionality I described working but am stuck with correct syntax.
Here is what I have so far:
Dim fs As New FileStream("C:Original.txt", FileMode.Open, FileAccess.Read) RichTextBox1.Text = "" Dim d As New StreamReader(fs)
[Code]....
Now I will need to declare every single row in RichTextBox1 as String then will have to get the bit I need will have to declare that as well(I will need from every row the string taht is between characters 96 and 104), also where do I keep the 23 criteraia values.
I'm sure there is an easy answer to this, and it may be "no," but is it possible to create an install file in VB Express 2010 and have that file deploy additional .exe files?
I developed a windows form program that calls fortan routines (in seperate .exe files) for different purposes. I would like to create an install file that deploys not only my VB program, but all of the supporting code.
Is this possible with VB Express 2010? I tried to search for threads about this, but didn't find any that explicitily answered this question.
Basically i am creating a console application that will create and store client information as a .txt file it is going okay but i have come across a slight hick up i want to use something on the lines of this .....
dim lastname as string Do Until Integer.TryParse(Console.ReadLine(), LastName) = False Console.WriteLine("Invalid input, Please try again") Console.Write("LastName:-")
[code].....
this works fine to trap out numbers from letters but the problem i am getting is when the program calls uppon LastName it is recording 0 and wanted to know if there is a way of getting past this ..... so basically i need a way to allow letter but not numbers and symbols and then dispay a pernolised error message but at the same time use Stream writer to save was the answer is in a .txt file.
I'm currently developing a download manager and converter for audio and video files. Does anyone know how can I get the music file from a specific folder from my computer (I already used openfiledialog) and putting it into a listview?
I'm having trouble with reading a .txt file line by line, converting it into a string, then putting it into a listbox. When I execute I get an error saying "IndexOutOfRangeException was unhandled" Here is my
I don't know whether it is simple or not because i am new to programming. my requirement is : In my vb.net winform application, the filenames of the files present in "D:Project" willbe displayed in DataGridView1 control. Now I want to load these files one after another into memory stream buffer and add the headers("ID","Name","Class") to the content in the file. Then I want to save these files in "C:" with "_de" as suufix to the filename i.e.,sample_de.csv.
I created an application that when a user logs onto their Windows account, a Form is displayed outlining the current Computer Usage policy set by the insitution and gives the user two options either Agree or Dis-Agree. The two options are in the form of buttons, with events that depending on what the user clicked, will create a log text file at a specified location, with enteries of Date,Time,CurrentUser, and if they agreed or disagreed. If they agreed the application after creating/amending the file will then terminate, otherwise it will update the file and then force Windows to logoff the current user.
Now I made a shortcut of the .exe of the application and placed it in the startup for all users, and yes the application loads at startup for all the users following the procedures mentioned above. The problem I am facing is, that if the current user logs off, or is forced to log off, and another user logs onto Windows, goes through the whole ordeal mentioned above, the application is denied access to the logfile that was created under the previous user, and thus crashes.
So my question is, how can I created a text file using vb 2008 application, that is accessible by multiple Windows users. I have even tried changing the location of the created file to the shared folder, but the end result is the same.
I'm looking for a way to (easily, by preference ;)) create a download link to a file on a separate file server.The situation is as follows: the application I'm developing (asp.net 2.0 in vb.net but I have a similar issue in c#, either solution works for me) will be run internally for a company.As is good practice, the file storage and web application are on two separate servers.I basically need to be able to create a download link to a file, the only available URL i have to access the file is servernamefolder1folder2folder3file.txt (can be any sort of file)[code]Which doesn't work for obvious reasons. It used to be set up to write that file to the application path itself and that worked perfectly, but it isn't good practice and that's why I'm changing it (or trying to).I read solutions about creating a download page and then having a table in your DB which holds the links and returns the proper web URL for download but the time constraint I am faced with unfortunately doesn't allow me to develop that.
Assuming I can provide a string with the full filepath to the file like the above, what is the easiest way to just create a link that, when clicked, downloads the document? I have 0 admin rights in this environment. That really isn't helping me. Let's assume I am given the correct link like above and have the appropriate file access rights and such.The above example does work in IE, but not in Firefox and Chrome. IE converts it to a file://servername/... link which does what it's supposed to, but FF and Chrome both actively decided that this is unsafe and have disabled it from their browsers.
I am making just a simple program that will create backup dummies of all the files in a specified folder. All I have is 2 text boxes, A and B, and a button to do the magic. What I want is for the user to input into Text Box A the location of all the files, and in Text Box B place in the destination folder, then when the button is pressed it will get the name of each file using a loop and recreate a new file with the same name and extension in the destination folder.For example:
C:FolderX has 10 files in it, each with the same extension (.wav), each file is ranging from 10mb to 100mb (this size is irrelevant) C:FolderY is empty
What I want to do is create each file from X into Y, however the files are all 0 bytes (no data inside them). I've managed to get a simple script that will do what I need but only if I specify the file name:
Code: Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click Dim Filename As String = My.Computer.FileSystem.GetName(TextBox1.Text + "test.wav") Dim SaveP As New System.IO.StreamWriter(TextBox2.Text + Filename) SaveP.Close() MsgBox("Files Created")
But what I need is someone to show me how to create a loop that will do this for each file in the folder, without me specifying each filename.
I have a list of points X(horizontal), Y(vertical), and Z(depth). I want to be able to plot them out so they can be viewed and since it is 3d I want to be able to rotate the image as well. There would be a line connecting each point to the next, until the end of my list. If possible I would also like to be able to click on an individual point on the image and be able to tell where that point is in my list.The problem is I don't have any idea on where to start on this. I know how to create some pretty basic/genaric 2d bitmaps but 3d and some of the features are an entire different story.
i would like to get some ideas on how to connect computers to play a LAN game.. the deadline for this project will be on the 27th of march so.The game that i'll be making is a counter-strike-like 2d game.. is it possible that i can finish this project before its deadline?
I'm normally an ASP.NET developer but my latest project has me writing a console app. For this console app to function, it needs two executables, two DLLs, an XML file that should be configured with a WinForm I've developed (so another .exe), and a working folder should be created (for when my console app runs). Further, it would be nice to have it automatically set up a Scheduled Task for batch operation.How do I package the various files into a self-extracting package? I'm playing with WinZip's self-extractor creator and it's okay, but I don't see a way for it to launch further processes, such as creating a working folder for the console or launching the WinForm above.Is there a way to create an auto-extractor in VB.NET where zipped contents are part of the "payload" of the .exe? It seems to me this would give me the most flexibility, as I could write a WinForm that does everything.
I'm a VB.net newbie and trying to write a simple program for installing in a few of my company's computers, most of which still use Windows XP.How can I specify when publishing in VS2010 that the program is for installation in XP?
