I've done some research into this using the MSD website; I have found that my applicaiton saves the Customer Details to the Customer File, but only as (spaces). No data is present in the file.
I'm creating an application that saves Customer data to a file. Once the Data is saved into the file, how would i then get it from the file into a ListView?

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.

Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

I designed a form from dragging across tables from data sources. All in all, bindingsources, tableadapters, dataset & tableadaptermanager, I have about 40 objects in the component designer tray.I found out that on a few occasions, Im not able to view the form design because of corruption or something. Sometimes, I even lost a bindingsource object or even a dataset object which caused errors. Has anyone come across such incidents? Is it advisable to have too many objects in the component designer tray?

I have a form with a listbox that when the form is opened I need it to display info from a file. I don't know what would be easier to work with Excel or a txt file, but it is in this format:

999-555-8618[code].......
I would like it to populate the list box when the form is loaded, but if I have to use a button to tell it to load that is fine also.On the same form I have 4 textboxes that ask for each of the above items (name, DOB, Level, PH#) and a button that when pushed I want it to save it to the same file where the above info was pulled from in the same format.The Show Contacts button doesn't have to be used if it is not needed.

I have a IF statement which is checking each row in the data table (for a match) and ELSE statement with commands which are executed if the If statement is not satisfied. Now I would like to write like so that it goes to the Else part BUT ONLY for values which are not satisfied in the IF statement. If I am more specific; I would like to calculate values if a match is found and just print them if it is not fond (usually there are both cases). Now the problem is the bold text; if there is a match found I don't want it processed BUT if the match is found I do. How can I write that?

I have this rather stupid litle excel issue which somehow just doesn't go away by itself;I'm creating a excel chart from three rows of information data. Each row has a header, so far so good. The first row exixt of calender data and I planned it to use them as my x-axis labeling. But somehow excel uses them as variables and changes them in to a third bar. Which is not what I had in mind when copied this litle piece of code.[code]

I've come across this code, which builds a .doc file, and lets you download it:
Private Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim strFileName As String = "GenerateDocument" + ".doc"

...but I don't know how to make the text bold, or create a table. I'm sure there's a better way.
