I wrote the code bellow and need the asociated .PGP file to have the text http:// included. the PGP file is namely read by Autocad which requers the "http://" in its text to be able to launch the desierd webpage. problem is , is that VBA is Auto formating the http:// as a code entatie and not writting it to the text based PGP file.
Can any one tell me how to achive what im after?
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click
Dim FILE_NAME As String = "C:\test.pgp"
If System.IO.File.Exists(FILE_NAME) = True Then
Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
objWriter.WriteLine((TextBox5.Text) + "," + " " + "START http://" + (TextBox6.Text) + ", 1,,")
objWriter.Close()
MsgBox("The acad.pgp file was successfully appended…")
Else
MsgBox("File missing reinstall or contact vendor…")
End If
End Sub
Hm, I'tried your code above in VisualStudio 2010. An empty file named C:\test.pgp was appended with the following text:
textbox5, START http://textbox6, 1,,
The text http... is right there. Sometimes, when I open the file in a viewer, this viewer automatically detects the http string and marks it as a hyperlink. But only in this viewer!
So the error seems to be somewhere else, not in the code?

I created a Visual Studio 2019 project that uses FileSystem.FileExists and both StreamWriter and StreamReader
I also created a folder named Resource with the intention of creating a txt file in this folder
Knowing I need to tell the Writer and Reader where to find the file I used these lines of code
Dim path As String = "C:/Users/Me/source/repos/TestForms/TestForms/Resource/"
If Not My.Computer.FileSystem.FileExists(path & "Check.txt") Then
Because I do not full understand how to deal with a SQLite database yet lets say I put the database in the folder Resource. And if I make a EXE package that will run on another computer that string path is by my best guess is not going to work
In the process of leaning I keep seeing this line of code. I see no path to the database
m_dbConnection = New SQLiteConnection("Data Source=MyDatabase.sqlite; Version=3;")
Granted I am dealing with a txt file now but if it was a SQLite database file
My Question is how does the connection know where the database is ?
I also need to import this reference Imports System.IO
Coming from NetBeans I got spoiled with Auto Import
Second Question Does VS 2019 not have an Auto Import feature?
I am adding a screen shot of Solution Explore
Tried to add Resource folder to Resources that did not work real well
Stream Reader Code below without error

line = reader.ReadToEnd.Trim

fs.Close()
tbHaveTwo.Text = "File Created"
tbHaveOne.Select()
Else
tbHaveTwo.Text = "File Found"

You should pretty much never be hard-coding absolute paths. If you want to refer to a path under the program folder then you use Application.StartupPath as the root and a relative path, e.g.
Dim filePath = Path.Combine(Application.StartupPath, "Resource\Check.txt")
Then it doesn't matter where you run your program from. For other standard folder paths, you should use Environment.GetFolderPath or My.Computer.FileSystem.SpecialDirectories. For non-standard paths, you should let the user choose with a FolderBrowserDialog, OpenFileDialog or SaveFileDialog and then, if appropriate, save that path to a setting or the like.
When it comes to database connection strings, some ADO.NET providers support the use of "|DataDirectory|" in the path of a data file and that gets replaced at run time. What it gets replaced with depends on the type of app and how it was deployed. For Web Forms apps, it resolves to the App_Data folder. For ClickOnce Windows apps it resolves to a dedicated data folder. For other Windows apps, it resolves to the program folder, just like Application.StartupPath. I think the SQLite provider supports it but I'm not 100% sure. If it does, you could use something like this:
m_dbConnection = New SQLiteConnection("Data Source=|DataDirectory|\Resource\MyDatabase.sqlite; Version=3;")
EDIT:
If you add data files to your project in the Solution Explorer and you want those to be part of the deployed application then you need to configure them to make that happen. Select the file in the Solution Explorer and then set the Build Action to Content and the Copy to Output Directory property to Copy Always or, if you intend to make changes to the file when the app is running, Copy if Newer.
When you build, that file will then be copied from your project source folder to the output folder along with the EXE. You can then access it using Application.StartupPath at run time. That means while debugging as well as after deployment, because it will be copied to the "\bin\Release" output folder as well as the "\bin\Debug" output folder. If you add the file to a folder in the Solution Explorer, that file will be copied to, hence the reason I said earlier to use this:
Dim filePath = Path.Combine(Application.StartupPath, "Resource\Check.txt")
Here is the working code to Create a Text file if it does not exist and if it does exist the user is notified.
We also were able to Write & Read from the Text file
One of the disappointments is we were not able to use StreamReader
We did solve this error where the file name was created like this "Check.txtCheck.txt This line of code below created the File this way in the folder Bin > Debug
If Not My.Computer.FileSystem.FileExists(filePath & "Check.txt") Then See Code for correct format
One other BIG lesson Do NOT create a folder and place your Text file in that folder
I am not sure using the code "Using" was a good idea further research needed on that issue

I have created my own text editor in Visual Basic 2013. I want to open text files with it from outside the application: to open them from the Desktop with double click or right click and open with.
I tried to use right click and open with but it doesn't work, it just opens up my application.
How I make my text editor the one that I open text files with?
You would have to use something like the Environment.GetCommandLineArgs method.
Put this in your form load event:
Dim CommandLineArguments() As String = Environment.GetCommandLineArgs()
If CommandLineArguments.Length >= 2 AndAlso String.IsNullOrEmpty(CommandLineArguments(1)) = False AndAlso IO.File.Exists(CommandLineArguments(1)) Then
Me.TextBox1.Text = IO.File.ReadAllText(CommandLineArguments(1))
End If
This will get the command line arguments sent to your application (which is the path to the file you are trying to open with your app) and check if the argument is an existing file. If so, it will read all the file's text into your TextBox.
Write this code in the form load event.
Private Sub form1_Load(sender As Object, e As EventArgs) Handles MyBase.Load
Dim fname As String = Command$()
If Not fname = "" Then
fname = Replace(fname, Chr(34), "")
Dim obj As New System.IO.StreamReader(fname.ToString)
RichTextBox1.Rtf = obj.ReadToEnd
obj.Close()
Me.Text = "Your Application Name " & fname
End If
End Sub
I am creating a text editor in VB.net with tabs and I am done so far. All I need is when the user saves the document or opens a document the name of the document shows up on the tab. I am using a separate tab control. I have it done but it shows the whole directory of the file. The only way to change the text on the tab is to change the text of the form I am using for the tab control to duplicate. So my code for when the user opens a file is:
Private Sub OpenFileDialog1_FileOk(ByVal sender As System.Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles OpenFileDialog1.FileOk
Dim alltext As String
filename = OpenFileDialog1.FileName
alltext = File.ReadAllText(filename)
FastColoredTextBox1.Text = alltext
Me.Text = filename
End Sub
But like I said it shows the whole directory of the file. Is there any way to make it just show the file name. The code for when the user saves the file has the same thing.
Try this:
Me.Text = System.IO.Path.GetFileName(filename)
I want to import a picture from folder which created by project when installed on user desktop but each user have different user name , how can i import from picture from dsektop user
Here is My code
Private Sub Button2_Click(ByVal sender As Object, ByVal e As EventArgs) _
Handles Button2.Click
PictureBox1.Image = Image.FromFile("(My.Computer.FileSystem.SpecialDirectories.Desktop, "New folder") \" + ID.Text + ".png")
end sub
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
this will resolve to the desktop folder for the current user. Are you really creating folders on the desktop? Usually data and subfolders are stored in AppData.
EDIT
I SUSPECT you might have need of this folder in other places and even if not it can be saved and 'fixed' before hand. Elsewhere, like when the app starts:
Friend mUserFolder As String
mUserFolder = Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
' your code was not adding the required backslash
mUserFolder &= "\Data\" ' append the sub folder name
Now to load the file in button click the code is simpler to read and debug:
PictureBox1.Image = Image.FromFile(muserFolder & ID.Text & ".png")
Also use & for concatenating strings instead of +
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim FILE_NAME As String = "C:\KVRequest.txt"
Dim aryText(4) As String
aryText(0) = "TextBox4.Text"
aryText(1) = "TextBox5.Text"
aryText(2) = "TextBox6.Text"
aryText(3) = "TextBox7.Text"
aryText(4) = "TextBox8.Text"
Dim objWriter As New System.IO.StreamWriter(FILE_NAME, True)
objWriter.Close()
MsgBox("Text file created in your C drive, attach this file in an email to someone#gmail.com Please check that all of the details are correct before sending.")
End Sub
What I am trying to do is get the text from the text boxes (4 5 6 7 8) to write into a text file. The code I have creates the file, but does not write text into it, can anyone give me a tip on how to get this working?
Thanks!
Edit: Also while I am here, I was trying to get it so button_1.enabled was only true if all of the text boxes had been edited, but I could not think of a practical way to do this, if you could help me with this I would also be very grateful!
Given the code posted above, the reason nothing is being written to the file is because you're not telling it to write anything to the file. You would need to add something like this between the creation of your StreamWriter and where you close the close method on it:
objWriter.WriteLine(TextBox4.Text)
objWriter.WtiteLine(TextBox5.Text)
etc...
Also, the simplest option for only enabling the save button is to create a Control.TextChanged handler for each of your text boxes (or use the one Sub to do it for all of them by adding all their events to the one handler method) and have it do something similar to:
If TextBox4.Text <> "" And TextBox5.Text <> "" And TextBox6.Text <> "" Then
Button1.Enabled = True
Else
Button1.Enabled = False
End If
