First time user on here, basically have been teaching myself VB and I enjoy it quite a bit! Basically I have a program now that has the File Drop-Down Menu with Open and Save options. I want to open and save in a .txt format. The open command will need to place the text in TextBox1 ; and the Save command will need to take the text from TextBox2 and save it as a .txt. I have gotten to the point where it will save it to a specified .txt file, but I would like the user to be able to "browse" the computer for where to open from and save files to.

So my two questions are, what is the most effeicent means of reading and writing a file and in what format should the file be in? When I say effeicent I mean, what utilizes the least amount of memory during the process, is fast, and disposable.
Example: XML, Text, something else. StreamReader / StreamWriter or what ever.
I have seen a few different ways of Reading/Writing Text files. What i am trying to achieve is a simple debug file in the most efficient way possible. Currently I have....
If System.IO.File.Exists(debugpath) = True Then
Dim Debugwriter As New System.IO.StreamWriter(debugpath, True)
Debugwriter.WriteLine(debugwrite)
Debugwriter.Close()
[code]....
1. Do I have to close and reopen the file each time I want to write to it.
2. In vbscript I would simply open the the file at the start of the script and close at the end is the same possible here.
so I want to make a button in one of my programs that writes text to a file. I know how to do that part. I use:

I have a quick question. One of the functions in the program I am writing is to take all of the data entered, compile it into an HTML document, then place that document into a folder.For the past few days, I have just been using a random folder on one of my hard drives to dump the file in, but the problem is that, in my code, I have supplied the folder location as a string ("E:Practice FilesDocuments"), and therein lies the problem. Trying to test my program on a separate system brought the bug to my attention; obviously, this program can only write this file to a location of E:Practice FilesDocuments, and if any other computer that runs this program doesn't have E:Practice FilesDocuments then there is going to be a problem in the program working the way I have intended
So what I would like to do is instead of having it write the file to "E:Practice FilesDocuments," have it write to the default My Documents folder so that the program is no longer specific to my machine only. The problem is, though, I have no clue what the right code is to use. I first tried using
System.Reflection.Assembly.GetExecutingAssembly().Location to write the file to the default installation directory. This would have worked, but since this is a VB.NET program, the default installation directory isn't in Program Files and doesn't seem to be meant for users to browse through for their documents, plus it seems that trying to write back to this directory causes some unhanded exceptions and whatnot. I figured it would just be easier to create a folder in My Documents rather than use the install directory (and probably smarter).

View 2 RepliesI want to write some stats to a text file every time a person loads a page. But every once in awhile I am getting at 'Could Not Open File, Already in use' type of error. I can not 100% replicate this error it is very erratic. My code is
Public Sub WriteStats(ByVal ad_id As Integer)

how can I lock and unlock the file so I stop getting the erratic errors?
I'm currently working on an application that allows users to select picture files and then categorize them into folders. Now I'm having two issues that are probably simple to fix but I only have a year of experience with vb so I just don't know how to fix them. The first and biggest issue is that once the user has selected and categorized a file, I want the program to select the next file in the folder that the first file was moved from. This way the number of clicks required is minimized. However I have no clue what I would need to do in order to accomplish this. Also, my other problem is that I want to be able to find the indexof a quotation mark but whenever I put it in the parameter it just reads it as a quote.
View 4 RepliesOk I know this question has been asked to death but I still have not seen a good answer. I have created an application in VS2010 using VB.NET. In my application I have an error log that is an XML file located in the Public gstLocalErrorLogLocation As String = Application.StartupPath & "ErrorLog"that gets written to in the event of an error so I can trouble shoot application easier. My application also downloads files from our FTP site and puts the files in Public gstLocalDownloadLocation As String = Application.StartupPath & "download"So I have files that get read and written to as well and created and deleted all in the Application.StartupPath which is either "c:Program Files(Application Directory)(Some Directory)(Some File)" or "c:Program Files (x86)(Application Directory)(Some Directory)(Some File)" depending on 32bit or 64bit Windows 7.
After creating the setup I install it on my test machine that have both Windows 7 32bit and 64bit.Everything in the application works great till I have to write to, delete or creat a file in those directories above. I know it is an access issue and the UAC. This will get installed on numerous systems so the options I have seen to change file or folder permission on the computers manually is not an option.What has to happen is after I install the application it just works like when you install it on XP. Some post have suggested that you us a user with administrator privilages or group which is all fine and dandy but the user I have used to test the application has all of that.
So what I am asking is how do you create an application with VS2010 in VB.NET that after creating a setup package and installing on Windows 7 will just work with out "Access to the path c:Program Files(Application Directory)(Some Directory)(Some File) is denied." If I have to install this on 100 Windows 7 computers it has to be a concreate no manually doing anything just install and work like when we installed on XP.
I have 19 .CSV files that hold engineering data in single and multiple Arrays.I would like to loop through the Directory that contains the files and open each file, fill the array and close the file and continue to the next in Alphabetical order.
This code tells me how many files I have now and will update if I add more.
Dim FolderPath As String = IO.Path.Combine(Application.StartupPath, "DATACSV Files")
Dim TestFolder As New IO.DirectoryInfo(FolderPath)
Dim FileCount As Integer = TestFolder.GetFiles().Count
FileCount give me my number of files but not sure how to continue. I have the code to open and read the file but not how to keep changing the file name for each new file name base on the number of files that exist.
I'm making a flash player and I've been trying to figure this out for months now and have posted several different topics but none of the answers fixed my problem.

I am writing a program that stores filenames, along with a lot of information about the files in a database. I need to be able to open these files in three different programs from my application. One of these programs, AutoCAD is the default program for the files, but the other two are more difficult. These two need to open the file in a program that is not the default for the file type. Eventually, I'd also like to allow users to point the application to the instance of AutoCAD, MasterWorks, or FeatureCAM that they want to open. I have found articles that explain how to open a file in a default application and articles that tell me how to open any application with a file name, but only 1 suggestion of how to control the program used to open the file. For some reason I cannot get AutoCAD to recognize the file I feed in if I use this method though, so I think it's wrong. This is the method I found that doesn't work:
Start("D:Program Files (x86)AutoCAD 2007acad.exe", file)file is a variable that contains my file name. Since this works fine when I take the program path out, I know the filename is correct, but AutoCAD says it is not.
A simple WebKitBrowser1.Navigate(localfilehere) doesn't work for some reason.
I tried adding "file://" to the URL but that didn't work either.
This seems ridiculous but is this functionality really not present?
I am programming using VB-2005 on a Vista Based machine. I am trying programmatically to open a PDF file that is Password Protected. I have worked out the steps required to open a non-protected PDF. Adobe tells me that it is not possible to pass a password to the PDF using the objects that come with the PDF Control. My question is can this be done in some other way, e.g. with WinExist etc.? Is WinExist and other such commands even available in Visual Basic?

View 1 RepliesOk hard to explain this one, it may be the codeproject addin i added recently or its a setting i have changed somewhere but when i'm debugging my app opens up many .cs files, kind of interesting but when i want to step through my code it goes into these files and when it errors it has no reference to where the error actually is. sometimes these files being opened have errors on them which i have had to correct for the code to work.
Has anyone seen this before and what could i do to stop it, i wish to confirm that it is this addon before i remove it (which i will do if it is this addon causing this).

I've tried to make it write "Name =" + txtname.Text but it won't work anymore. And as well as that, I don't think It will load the text back from the ini file.

Basically I'm writing a program that records all the financial transactions I make. You type in what it is, whether it is going in or out, the date and the price. I will get on to adding the sums up later but that's important at the minute. With one record the program worked perfectly but as soon as I added an array to the records variable it stopped working and complained about a null value.

View 4 Repliesseeing as '.dat' files contain only what you want them to and there is no preset encryption for them etc could I write data to one by using this simple process:
1) Change file extension to '.txt'
2) Decrypt
3) Write
4) Encrypt
5) Change file extension to '.dat'
and pretty much the same for reading it. or am I thinking to simply?
I thought of the above way as i know how to write to text files already, but is this the best way to do it? or is there a better way?
EDIT: Nevermind you just write to it like a text file and encrypt/decrypt it. request lock/delete from mod.
