How can I make it that if a file exists, it will rename it with the exact name, but with a number by it? For example, my program takes a picture and names it "screenshot." I want it to make it say "screenshot1," if "screenshot" is already used, and so on. This is what I tried, but didn't work.
Dim name as String = "Screenshot"
If File.Exists("C:This" & name & ".png") Then
screenshot.Save("C:This" & name + 1.ToString & ".png",
I haven't used System.IO before, and I'm a little stuck.I need to check if a file exists, for example C:Documents and SettingsverraineDesktopSURNAME Firstname v1.docx, if this file exists the filename has to become v2, and so on. Usually there will only be a v1, but in the case that a clients position changes we have to be able to save the new version without overwriting the old one.
How would I be able to do this efficiently? I'm uncertain to say the least. Because, if I manage to find out how to save the file as a different number, that's alright, but if that next number exists as well? I can only think of ways to do this that require a lot of code.
When I try to save the picture and the picture is already existed it show an error
Me.Location = New System.Drawing.Point(50, 50) Create a new Bitmap object with the screen bounds Dim both As Bitmap = New Bitmap(166, 261, Imaging.PixelFormat.Format32bppArgb) Create a Graphics object that will process the screen shot front and back Dim bothgraph As Graphics = Graphics.FromImage(both) Copy the screen contents bothgraph.CopyFromScreen(0, 0, -506, -279, Screen.PrimaryScreen.Bounds.Size,opyPixelOperation.SourceCopy)' Save the resulting graphics
i want to check if a file exists in the Application.StartupPath. I tried My.Computer.FileSystem.FileExists but that checks the whole computer doesn't it. ? How do i check if a file exists in a directory?
I have a folder that contains .txt, .pdf, etc files. I want to check if the folder contains a .txt file.If yes, I have to perform some action, if no, no action will be performed.I have this sample code to do the above, but with the know .txt file name.
I have a small problem that I was hoping you could help me with. I was wondering if anyone could show me how to make it so when I save my textbox to the file it would show new lines for the text.
I feel bad to post another question, but I can't find a answer to this kind of question anywhere.I am using some text files as a database. To seperate the records I use the # symbol. I am just using the write method to do this.... so when I open the text file it's a very very very loooooooooooooooooong line.
MySQL databases exists for saving values as strings (text only). Is there any way that i could store files with the same speed as a mysql command ? I know that it depends on the file size but lets say that the file is "Avatar.jpg" 50KB... I ve tried FTP but this is not what im looking for. e.g. You want your users been able to upload a file like the [Add This Attachment] button does in dreamincode.net and you dont have any background on PHP/HTML/Javascript/ASP.NET just VB.NET and the basics of MySQL plus you dont want to use it for a website. How do you accomplish this? Something silly that ive tried was opening an image as text then update the mysql server with that text but it didnt work backwards after i wrote the text on the file and oppened it ...it said that the image was corrupted.

I've got a SQL Server and I need to save files somewhere and I guess I hsave two options
1. Save the file path
2. Save the file in the database.
Issues with option 1 are for complicated reasons the file path is not the same for everyone. I'm talking about saving 200-400 per month, is there any issues with saving them into a SQL Server Database that is used by internal employees only?
Currently I am saving data from my applications by saving a text file via a stream reader as a string. I have come to a problem. In my current application, I have an array of the following structure:
I am trying to use the BGW to save a DGV to excel file, but don't know how to do it correctly, specifically setting the savefile name this code doesn't work gives me:
'System.Runtime.InteropServices.COMException' occurred - Make sure the specified folder exists. - Make sure the folder that contains the file is not read-only. - Make sure the file name does not contain any of the following characters:
Ensure that your Main function has STAThreadAttribute marked on it. This exception is only raised if a debugger is attached to the process. I also tried doing the Save in the BGW RunWorker Completed event but then there is no file name. It seems I need to pass the file name the user inputs in the SaveFileDialog to the BWG WorkerCompleted event somehow

Basically I have a VB.net word processor application, With a; Rich Text Box Header Label(as system.windows.forms.label) Footer Label(as system.windows.forms.label) The printing is no problem, but the problem I am having is saving the header and footer label's text into the RTF file and also loading these into the header and footer labels.
When I save settings for an application using My.Settings.Save it saves it in %AppData%LocalCompanyname. Because I don't want my app to be installed and I want it to be a just .exe file, and it leaves some files on that computer. I like it to be in my apps location. Can I change that default location?

i am trying to do a text file to save some configurations. Basically when the application starts it will check if the text file is exist, if not it will create a new text file. Now i'm having a problem is when i try to append the newly created/exist text file, sometimes i need to press the 'save' button many times to update the text file.
Here is part of my When the form loads

I am pretty good with visual basic and visual studio, but the one problem I have is saving... I am currently creating a game, and it has a lot of variables, I want o be able to save all those variables to a text file and then re-open it later. When it is open, i want the variables to have the original value from the text document.
To sum it up: I need variables to be saved in a text file, and then be able to open the text file back and have the variables have the proper values from the text file.
I have been searching around google, and I found ideas, but I have no idea how to use them. Like using XML or saving a table with " TextFile.WriteFromTable" "TextFile.ReadToTable" but I don't exactly get how to use those (the posts weren't too clear)
below the form i have a button that saves the data to a text file called 'mailinglist.txt'
So i enter the data into the fields and click the button like as follows:
Full Name: John Smith Amount Contribted in �: 40
However..... when i go view the text file it displays John smith40, which i want a space between the name and the numeral.
Also as i want a maximum of 5 people added to the mailing list, i would like a function that lets me somehow "adds" an extra 4 people to the text file without overwriting the 1st name, and uses the same "current" form displayed to the user.
Here is the code as follows:
Public Class Form2 Private Sub TextBox2_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles TextBox2.TextChanged
I am able to browse to a file and save its path in a textbox, but the slashes from path are removed when saved to the database. C:Program FilesApplicationDocStudio.bmp becomes C:Program FilesApplicationDocStudio.bmp Public Class FormSettings Dim Result As String [Code] .....
Public Class Form2 Private Sub TextBox1_Click(sender As Object, e As System.EventArgs) Handles TextBox1.Click OpenFileDialog1.FileName = Nothing OpenFileDialog1.ShowDialog() If Not OpenFileDialog1.FileName = Nothing Then TextBox1.Text = OpenFileDialog1.FileName
Here's my code: System.IO.File.Move(Form6.OpenFileDialog1.FileName, "Temp") I'm trying to make it so that the program copies the file that you select in the OpenFileDialog and moves it into the "Temp" folder. It gives me an error saying: Cannot create file when file already exists.
I am trying to write(what I thought would be a simple piece of code. I was wrong.
What I am trying to do is to get an application to check if a file exists, However, I have it wrong as the file obviously does exists, but when I run the application it tells me it does not.
Imports System.IO Public Class check Dim checkfile As New FileInfo("C:\HelloWorld")
