We have to learn VB.NET for the semester, my experience lies mainly with C# - not that this should make a difference to this particular problem. I've used just about the most simple way to save a file using the .NET framework, but Windows 7 won't let me save the file anywhere (or anywhere that I have found yet). Here is the code I am using to save a text file.

I have multiple file upload boxes on a form in my mvc3 application. Request.Files shows 3 files when I put a break point in the below function and look at it.. Problem is other than coding a counter and using a select case I dont see a way to handle saving each file name to the database column it belongs to... Is there away to assign the variable on the fly I guess you could say So that the foreach loop would drop the file in the correct column. Ie handoutFile1, handoutFile2 , handoutFile3, Etc. As it stands the below will overwrite the filename in handoutfile1 every time the loop is gone through. I thought about throwing a counter in the loop and just put a select case on it to assign the db column based on the counter number. Seems like a cheap work around though. [Code]

Is there a way to copy files where it gives you the option to overwrite all and show graphically the files being copied, in much the same way when copying files within windows.What I have at the moment is this:
My.Computer.FileSystem.CopyFile(DataDirectory.DataSource, BackupPath & "Restel.bak", True)
For Each FileFound As String In My.Computer.FileSystem.GetFiles(SystemDataPath & "", FileIO.SearchOption.SearchTopLevelOnly, "*.rtf")
FileName = My.Computer.FileSystem.GetName(FileFound)
My.Computer.FileSystem.CopyFile(FileFound, BackupPath & "" & FileName, FileIO.UIOption.AllDialogs, FileIO.UICancelOption.ThrowException)
Next
which overwrites automatically or shows it graphically prompting each time if the file already exists.
Background: I have read a bunch of techniques to handle compression. I don't think SmartZipLib handles 7z. System.OS.compression does not seem to handle rar or 7z. I am trying to find one approach for all.The tools within Windows XP seem to handle them all from inside the file manager (at least on my computer).Question: how can I decompress all these files using the windows utility? I am guessing it is some sort of Shell command. Alternatively, is there another option?

View 5 RepliesMy students did a tutorial in HTML Help Workshop to add Help files to a VB 2008 Windows application. They zipped the files and uploaded them to our class web site.
I downloaded them at home, unzipped, and tried to check, but every one shows Table of Contents or Index and cannot find the .htm documents for the topic. The same thing happened in my office. However, these projects work correctly in our classroom
lab and do display the .htm files.
I have cooked up my first iteration of a code generator which creates the basic Entity models from a SQL Database Schema. Currently, It will scan a SQL Db Schema, and create .vb code files complete with private members and Public property declarations for every User table in the Database. My next step is having it add the basic CRUD procedures as well. Are we mere mortals able to access whatever technology allows the Partial class files created by vs to be hidden/Linked to their "parent" files, such as the Partial Class files for Windows forms or any other designer-generated control? My thinking is that it would be handy to be able to re-generate code files from the database if necessary to reflect changes in the schema, without overwriting any other properties or methods added to a class in addition to those derived from the database. SO I am hoing I can have the Auto-generated output go to a Partial Class file, and then use a regular class file of the same name for the rest of the code. My Concern is the multiplicity of files that might result, so I was hoping it is possible to "tuck them in" to the parent code file in the Class View.

I wrote windows app to upload files to different FTP sites by picking the files from different folders.A log is displayed by appending text to the textbox at every step.Textbox is ReadOnly.
Issue:When app is loading a bf file to FTP and if user tries to scroll the textbox,the form is hanging and going to Not Responding.?
Ok 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 a slight problem understanding how the following code works, it's specified in an example I have that the code is to check if FileName is a valid path for a text file and other things of course but I'm just interested in that part(checking it's a valid path). Here's the code:

I have a routine which populates a DataGridView. I generate the data on the fly in arrays and the populate the datagridview simply by saying
For each Row in DataGridView1.Rows
DataGridView1.Rows(row.index).Cells("PastColumn) = Array(row.index)
Next
I am not saving the data to log files. I only display the results at the end of my routine. When I close the project the data is lost.I am trying to understand why one would bind data. Would you do this in the case where you are saving the data to a file and you want the datagridview to update when the file is updated or loaded again at another time?
is there any VB.Net existing saving function?

I'm having some problems with people saving text files using my program, but only people using Vista. Since I don't use Vista myself, I'm not sure what this is but it's not a problem on any machine running XP.
Note that my file saves just using the standard Savedialog box and Filestream/Writeline commands.
From what my customers are telling me, the save dialog comes up fine and there is no error as the file appears to save, but when they look for the completed text file, there's nothing there.
I am trying to learn XML, for which i have created a simple Employees Program. I want to save the records of the employee in an xml file, so far i have the following code:

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.

I have been able to write to the file i need to and i have been able to log in. However i can only log in for the first saved account. when i hover over the stored variable whilst stepping through it appears that unnecessary gaps have been added to stored information...User.stored username is the data structure type that i have stored information as...
user.storedUsername = " TestStaff "
I believe it should be like this:
user.storedUsername = "TestStaff"
I am working on saving excel objects to a directory of my choosing. I am able to use a folder browser dialog to select the save location and the saveas method within the excel interop and i am able to create a file in the folder i select with the name i choose. The issue is that when i later go to open that file it is blank. no workbooks no worksheets etc . Just a seemingly blank file in the proper location with the proper name.
It should be noted that if i single click on the report icon to open it the microsoft browser window does show a tiny preview of what seems like the correct report.
