I am trying do display a pdf file on a form which contains a Web browser. I have previously used the below code which sometimes works but now I am constantly getting an error at line webBrowser2.Navigate pdfFilePath. The pdf file exists in the path and is named correctly. Please see the rest of code and help if you can:
Sub loadPDFFile()
Dim webBrowser2 As WebBrowser
Dim pdfPath As String
Set webBrowser2 = webControl.Object
pdfPath = Application.CurrentProject.Path & "\Internal Framework Summary.pdf"
webBrowser2.Navigate pdfPath
End Sub
Private Sub Form_Open(Cancel As Integer)
Me.webControl.ControlSource = Application.CurrentProject.Path & "\Internal Framework Summary.pdf"
End Sub
Private Sub Form_Load()
loadPDFFile
End Sub
Current Registry setting:
You may need a Registry setting:
HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\Main\FeatureControl\FEATURE_BROWSER_EMULATION
Try setting it to 0 (zero) to make the control to use the current browser emulation.

and my comment of 2020-11-13.
Bonus tip:
After setting MSACCESS.EXE to your preferred value, do
check the setting for OUTLOOK.EXE. Adjusting that will probably make
most of your received e-mail newsletters render as intended.
To display the file, use this ControlSource:
="=" & [URL]
where URL is the field holding the full path to the file wrapped in octothorpes, for example:
#http://africau.edu/images/default/sample.pdf#

I am trying to save a image from webbrowser but can't find an answer for it.
Example of the problem is the URL is hxxp://domain[.]com/image/?img=1234 on webbrowser it shows the image and the source is <img src='hxxp://domain[.]com/image/?img=1234'>..
I was unable to save it using the My.Computer.Network.DownloadFile and MemoryStream(tClient.DownloadData methods.
In order to download the file, I will need to session cookie also?
How can I do this?
Any image that you see in the WebBrowser has already been downloaded to your computer. It is normally cached in the folder:
C:\Users\<username>\AppData\Local\Microsoft\Windows\Temporary Internet Files
or whatever other folder is set in Internet Options. You can get your image from that folder.
The following program shows how to copy file TDAssurance_Col.png from the Temporary Internet Files folder to the C:\Temp folder.
Module Module1
Sub Main()
CopyFileFromTemporaryInternetFolder("TDAssurance_Col.png", "C:\Temp")
End Sub
Public Sub CopyFileFromTemporaryInternetFolder(filename As String, destinationFolder As String)
' Search actual path of filename.
Dim temporaryInternetFilesFolder As String = IO.Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.InternetCache), "Content.IE5")
Dim pattern As String = Path.GetFileNameWithoutExtension(filename) & "*" & Path.GetExtension(filename)
Dim pathnames() As String = Directory.GetFiles(temporaryInternetFilesFolder, pattern, SearchOption.AllDirectories)
' If file found, copy it.
If pathnames.Count > 0 Then
File.Copy(pathnames(0), Path.Combine(destinationFolder, filename))
End If
End Sub
End Module
I want to add a handwritten digital signature to some of my company's forms.
The goal is to, select a document, add a signature (through the use of a drawing pad, which can be done with Excel's Ink Tools) and store the file in the server as PDF. This would cut out the necessity of printing and then scanning the form back in to obtain a signature.
I'm using Excel for the main interface for file manipulation and search. I've not found any references/libraries for the use of Excel - Ink Tools through VBA.
How do I start Ink Tools Objects in VBA? Would I have to use a different software to get the signature?
Update:
After #Macro Man pointed me in the right direction I found some material that helped get the eSignature up and running.
I've found some material on MSDN Digital Ink Signatures - Concepts and Technologies and InkPicture Class that talk about the Ink collection on VB.net and C# through a PictureBox/Userform , this coupled with the InkEdit Control in another Stackoverflow response in which I realised that VBAs tool box had a InkPicture Control additional control that could be utilized to collect the handwritten eSignature through User form.
Please find below step by step:
In VBAs toolbox on additional control under Tools > Additional Controls there is the InkPicture Control which allows you to create a signature Userform.
Once Added InkPicture can be used as any other control on the toolbox.
Then its a case of initialising the UserForm for the Signature request. I'm using a drawing pad, but other hardware should work as well.
And storing or utilising the resultant image at need, in my case saving a temp version in the server to then resize and add to a Word document.
Edit:
After answering a similar question in here, on how to use Userform InkPicture to input image signature into a worksheet/specific cell, I thought I'd edit this answer for those interested.
The below code will allow you to, open the userform so the user can sign the ink field, save the image temperately, add the InkPicture to your worksheet and kill the temp image.
Set up your UserForm (mine is set up like this, with a couple extra options) the UserForm is named Signature_pad, the essential option you need is Private Sub Use_Click().
This is the code inside the Userform:
Private Sub Use_Click()
'dim object type and byte array to save from binary
Dim objInk As MSINKAUTLib.InkPicture
Dim bytArr() As Byte
Dim File1 As String
'get temp file path as $user\Temp\[file name]
FilePath = Environ$("temp") & "\" & "Signature.png"
' set objInk as image/strokes of InkPicture control form object
Set objInk = Me.SignPicture
'if object is not empty
If objInk.Ink.Strokes.Count > 0 Then
'get bytes from object save
bytArr = objInk.Ink.Save(2)
'create file for output
Open FilePath For Binary As #1
'output/write bytArr into #1/created (empty)file
Put #1, , bytArr
Close #1
End If
'set public File as file path to be used later on main sub
Signature.File = FilePath
Unload Me
End Sub
Private Sub Cancel_Click()
End
End Sub
Private Sub ClearPad_Click()
'delete strokes/lines of signature
Me.SignPicture.Ink.DeleteStrokes
'refresh form
Me.Repaint
End Sub
Below is the Main sub (Module called Signature) to call the userform and handle the signature, you can call this Sub with a button or form another Sub.
'public temp file path
Public File
Sub collect_signature()
'Dim and call userform
Dim myUserForm As Signature_pad
Set myUserForm = New Signature_pad
myUserForm.Show
Set myUserForm = Nothing
'insert image/signature from temp file into application active sheet
Set SignatureImage = Application.ActiveSheet.Shapes.AddPicture(File, False, True, 1, 1, 1, 1)
'scale image/signature
SignatureImage.ScaleHeight 1, True
SignatureImage.ScaleWidth 1, True
'image/signature position
SignatureImage.Top = Range("A1").Top
SignatureImage.Left = Range("A1").Left
'delete temp file
Kill File
End Sub
Be sure to rename either the Userform Name and Buttons Name Or the code to match the names of you buttons.
Is it the InkEdit Control you're after?
This is one of the standard libraries that you can find in Tools->References
I have a Webbrowser control in a form which displays a pdf file. I have to specify the URL as the file location on my computer.
eg.
E:\Folder\Manual.pdf
Both the pdf file and the program are in the same folder.
How do I specify the URL so that when I move the folder onto another drive, it opens the same pdf file?
The location of your application is
Dim path as String = My.Application.Info.DirectoryPath
The you could use:
Dim pdffile as String = IO.Path.Combine(path, "pdffile.pdf")
WebBrowser1.Navigate(pdffile)
If I understand you correctly, then:
Dim myPdf As String =
IO.Path.Combine(IO.Directory.GetParent(Application.ExecutablePath).FullName, "myPdfFile.pdf")
Another way you could do it is by using something like the code below;
Private Sub FamilyLocateFile_Click(sender As Object, e As EventArgs) Handles FamilyLocateFile.Click
If LocateFamilyDialog.ShowDialog = DialogResult.OK Then
FamilyWMP.URL = LocateFamilyDialog.FileName
ElseIf LocateFamilyDialog.ShowDialog = DialogResult.Cancel Then
MsgBox(MsgBoxStyle.Critical, "Error!")
End If
End Sub
What this will do is play a file in a Windows Media Player ActiveX object. The file can be selected with an OpenFile Dialog, which in this case is called LocateFamilyDialog. You don't need the ElseIf part of the statement, but you will need to insert an open file dialog and a control that can display PDFs. I think it'll work with WebBrowsers, but I'm not sure.
Private Sub Button7_Click(sender As Object, e As EventArgs) Handles Button7.Click
Dim Newline As String
Newline = System.Environment.NewLine
System.IO.File.WriteAllLines("C:\Users\Sang\Desktop\filename.txt", Result1.Lines)
System.IO.File.AppendAllLines("C:\Users\Sang\Desktop\filename.txt", Result2.Lines)
System.IO.File.AppendAllLines("C:\Users\Sang\Desktop\filename.txt", values.Lines)
End Sub
This is my coding for making a text file on my desktop. However, my friend can not run this code because this code is only for myself as you can see above. I would like to use a folderbroswerdialog to generalize this coding for everyone. To be specific, if a user pressed this button on the form, folder browser should ask him where he wants to save this text file and text file should be saved in the directed folder or desktop. I tried to do it on my own by looking at many youtube videos and resources but I failed. How should I proceed this?
You can use the Environment.SpecialFolder Enumeration which contains the ubications of the system's directories that you can retrieve using Environment.GetFolderPath method :
Dim DesktopDir As String =
Environment.GetFolderPath(Environment.SpecialFolder.Desktop)
Then you can use the Path.Combine method to properlly combine a directory/file path:
Dim OutputFile As String =
IO.Path.Combine(DesktopDir, "filename.txt")
Then:
IO.File.WriteAllLines(OutputFile, "Text Here")
Take a look here for using the FolderBrowserDialog:
http://msdn.microsoft.com/en-us/library/system.windows.forms.folderbrowserdialog(v=vs.110).aspx
PERFECTLY great examples there.
Hey guys before I was just hiding the parent form, but now when I try to read from the parent file it says it can't because it's already running in a process. I followed some tutorial and it said to go to the project properties and have the application stop running when all the forms are closed.
But now since I did that it says the directory can't be found probably because I am reading the input from the parent form. Anyways here is my code
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" + frmLogin.txtUser.Text))
How should I go about doing this?
Edit:
Private Sub btnHunter_Click(sender As System.Object, e As System.EventArgs) Handles btnHunter.Click
selection = "Hunter"
writeData.classSelection()
End Sub
This is what I have when the button is clicked.
Here is the classSelection sub:
Public Sub classSelection()
If frmClass.selection = "Hunter" Then
writeFile1.WriteLine(frmClass.selection)
End If
If frmClass.selection = "Gatherer" Then
writeFile1.WriteLine(frmClass.selection)
End If
If frmClass.selection = "Farmer" Then
writeFile1.WriteLine(frmClass.selection)
End If
writeFile1.Close()
End Sub
The error points to this line:
If frmClass.selection = "Hunter" Then
Saying part of the file path cannot be found.
If you want to read input textbox in closed parent form, you have to declare public var
Make a new module in your project .. and add this
public sLogin as String
And before you hide or close frmLogin .. add this
sLogin = txtUser.Text
So, you could change your code with
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & sLogin))
matzone has given you a good hint. And to check exactly what your path is, just add a MessageBox using variables :
Dim writePath1 As String
Dim writeFile1 As StreamWriter
writePath1 = "C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & sLogin
If MessageBox.Show(writePath1, "Continue ?", MessageBoxButtons.YesNo) = DialogResult.Yes Then
writeFile1 = New StreamWriter(File.OpenWrite(writePath1))
' ...
writeFile1.Close() ' Very important ! Adrian pointed it out.
End If
^^ and if it works, you can discard the Dialog test or replace it by some test code like If File.Exists(...)
However, I don't understand wether you want to close the parent Form or hide it. It's different !
Closing the parent Form will discard any access to parent Form members, including txtUser.Text.
If you want to close the parent Form, the ChildForm should not be a child of that parent you are trying to close, or you must just hide the parent Form :
frmLogin.Hide() ' Not frmLogin.Close()
If you close frmLogin, frmLogin.txtUser won't be accessible, or use sLogin provided by matzone instead. Alternatively, you should pass frmLogin.txtUser.Text value to a custom property of ChildForm.
Imports System.IO
Public Partial Class ChildForm1
' Inherits System.Windows.Form
' ...
Private _txtUserFile As String
Public WriteOnly Property TxtUserFile() As String
Set(ByVal NewFileName As String)
_txtUserFile = NewFileName
End Set
End Property
Public Sub LoadFile()
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" & txtUserFile))
' ...
writeFile1.Close()
End sub
' ...
End Class
Then use this in parent Form :
MyChildForm.TxtUserFile = Me.txtUser.Text
' Me.Close() ' This will definately KILL Form1 (the parent one)
Me.Hide() ' Always use Hide() until you'll terminate your Application
MyChildForm.Show()
MyChildForm.LoadFile()
^^ but this is not a good code either ! Your problem remains unclear (at least for me)
"Still saying it can't find part of the path", then check the path..
Does the file actually exists ?
Does the path contains glitch ? (use the provided MessageBox test)
Does your account can access that directory ? (Windows configuration and account levels)
Well !
In fact, the problem could be somewhere else.
For example, I was able to reproduce your exception by providing an empty string [""] as the value of, either :
frmLogin.txtUser.Text ' = ""
' or
sLogin ' = ""
' or
txtUserFile ' = ""
In fact, I get the "Could not find a part of the path..." exception because the StreamWriter couldn'd read/write to a File, as I didn't provided a valid FileName for that file. As the filename parameter was an empty string "", the provided path for StreamWriter was just representing a directory instead of a file and an exception was raised.
Now, you should check wether you have a valid path before building a new instance of StreamWriter to get sure you are actually pointing to a File ?
Dim writeFile1 As StreamWriter
Dim MyEntirePath As String = "C:\Users\...\Accounts\" + frmLogin.txtUser.Text
MessageBox.Show(MyEntirePath) ' would be enough to be sure your path is correct
' Some test code here...
If everythingOK then ' create the StreamWriter...
writeFile1 = New StreamWriter(MyEntirePath)
' ...
' ...
Also, it's not a good idea to create your streamwriter, and use it in another part/method of your code. You never known if one day, you'll change your code, and forget to make the link between
Dim writeFile1 As StreamWriter = New StreamWriter(File.OpenWrite("C:\Users\Nick\Documents\Visual Studio 2010\Projects\LoginFixed\Accounts\" + frmLogin.txtUser.Text))
' plus
Private Sub btnHunter_Click(sender As System.Object, e As System.EventArgs)
...
End Sub
' plus
Public Sub classSelection()
...
writeFile1.Close()
End Sub
^^ too much "here and there"...
You'll obviously also get an exception if you try to click btnHunter twice.. I don't know what is the purpose of your code nor how it works, it looks like a game.. But I would use File.Exist(..) checks, create the file before, if none, and put that in a Try/Catch to check if I eventually don't have administrator rights to write to that directory. Otherwise, make a code that allow user to read/write files to a custom folder. Andalso, you have :
Application.StartupPath
^^ Very usefull, like :
Dim MyFilePath As String = Application.StartupPath + "\Datas\MyText.txt"
After two weeks of coding, I usually forget where I put those "C:\blabla.." or "D:\gnagna\" or what classes actually uses those absolute reference paths. I've dropped this way of getting directories long ago since the day I moved to Win7 on another computer and all such applications I developped using that approach was doomed...
