I got application in .net and I would like to display excel sheet with macro inside my form. I found code that display excel file inside panel and everything works ok but once I run macro its frozen. If I will not run macro Its work fine.
Imports excel = Microsoft.office.interop.excel
Imports office = Microsoft.office.core
Public Class Form1
Declare Auto Function SetParent Lib "user32.dll" (ByVal hWndChild As IntPtr, ByVal hWndNewParent As IntPtr) As Integer
Declare Auto Function SendMessage Lib "user32.dll" (ByVal hWnd As IntPtr, ByVal Msg As Integer, ByVal wParam As Integer, ByVal lParam As Integer) As Integer
Private Const WM_SYSCOMMAND As Integer = 274
Private Const SC_MAXIMIZE As Integer = 61488
Private Sub btnShowExcel_Click(sender As Object, e As EventArgs) Handles btnShowExcel.Click
Dim sExcelFileName = "D:\123.xlsm"
Dim oExcel As New Excel.Application
oExcel.DisplayAlerts = False
oExcel.Workbooks.Open(sExcelFileName)
oExcel.Application.WindowState = excel.XlWindowState.xlNormal
oExcel.Visible = True
SetParent(oExcel.Hwnd, pnlExcel.Handle)
SendMessage(oExcel.Hwnd, WM_SYSCOMMAND, SC_MAXIMIZE, 0)
End Sub
End Class
Could anyone help me to change this code or find different one so I could display excel file with macro and macro will work without any problem.
Thanks

This question is basically regarding to loop all workbooks in all excel instances!
Your main issue you are facing is you are not using any of the process's you come across. Therefore, you will not get anything that way. Inside of the loop for the process's you then create a new instance of ExcelApplication and then try to loop through the Workbooks. By default when you do this there is only 1 at that time, hence why you get only 1 Workbook and also why you will only ever see 1 Workbook.
Solution (Tried & Tested)
You need to look into Windows API calls to get what you need. A few of them are:
GetDesktopWindow()
EnumChildWindows()
GetClassName()
EnumWindowsProc()
AccessibleObjectFromWindow()
Imports Microsoft.Office.Interop
Imports System.Runtime.InteropServices
Public Class Form1
Private Declare Function GetDesktopWindow Lib "user32" () As Integer
Private Declare Function EnumChildWindows Lib "user32.dll" (ByVal WindowHandle As IntPtr, ByVal Callback As EnumWindowsProc, ByVal lParam As IntPtr) As Boolean
Private Declare Function GetClassName Lib "user32.dll" Alias "GetClassNameA" (ByVal hWnd As IntPtr, ByVal lpClassName As String, ByVal nMaxCount As Integer) As Integer
Private Delegate Function EnumWindowsProc(ByVal hwnd As IntPtr, ByVal lParam As Int32) As Boolean
Private Declare Function AccessibleObjectFromWindow Lib "oleacc" (ByVal Hwnd As Int32, ByVal dwId As Int32, ByRef riid As Guid, <MarshalAs(UnmanagedType.IUnknown)> ByRef ppvObject As Object) As Int32
Private Const OBJID_NATIVE = &HFFFFFFF0
'Required to show the workbooks. Used in function to add to.
Private lstWorkBooks As New List(Of String)
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
lstWorkBooks.Clear()
GetExcelOpenWorkBooks()
End Sub
Private Sub GetExcelOpenWorkBooks()
Try
'Get handle to desktop
Dim WindowHandle As IntPtr = GetDesktopWindow()
'Enumerate through the windows (objects) that are open
EnumChildWindows(WindowHandle, AddressOf GetExcelWindows, 0)
'List the workbooks out if we have something
If lstWorkBooks.Count > 0 Then MsgBox(String.Join(Environment.NewLine, lstWorkBooks))
Catch ex As Exception
End Try
End Sub
Public Function GetExcelWindows(ByVal hwnd As IntPtr, ByVal lParam As Int32) As Boolean
Dim Ret As Integer = 0
Dim className As String = Space(255) 'Return the string with some padding...
Ret = GetClassName(hwnd, className, 255)
className = className.Substring(0, Ret)
If className = "EXCEL7" Then
Dim ExcelApplication As Excel.Application
Dim ExcelObject As Object = Nothing
Dim IDispatch As Guid
AccessibleObjectFromWindow(hwnd, OBJID_NATIVE, IDispatch, ExcelObject)
'Did we get anything?
If ExcelObject IsNot Nothing Then
ExcelApplication = ExcelObject.Application
'Make sure we have the instance...
If ExcelApplication IsNot Nothing Then
'Go through the workbooks...
For Each wrk As Excel.Workbook In ExcelApplication.Workbooks
'If workbook ins't in the list then add it...
If Not lstWorkBooks.Contains(wrk.Name) Then
lstWorkBooks.Add(wrk.Name)

Is there a way to crack the password on an Excel VBA Project?
(25 answers)
Closed 7 years ago.
I am wondering about how safe is the VBA password on MS Office 2013.
I've searched online and there are a bunch of websites selling software to do it, is it reliable?
I want to develop some security around my office files that would depend on the VBA code inside, but if the vba code inside can be easily changed/seen it's non sense going that way.
Thanks
Using this answer as reference : Is there a way to crack the password on an Excel VBA Project?
Instead of doing all the Hex stuffs. You can try this. It will work for any files (*.xls, *.xlsm, *.xlam ...). Tested and works on Excel 2007, Excel 2010 and Excel 2013 - 32 bit version.

I do not know how to make the simplest in the world resizable UserForm. What I have seen on different forum threads are terrible behemots (huge as the Universe libraries doing too much). But I need a simple, one stroke solution and I hope it exists. At this moment I have this code:
Dim myForm As UserForm1
Set myForm = New UserForm1
myForm.Caption = "Attributes"
myForm.Show
And I have UserForm_Initialize() which does some extra work. What is horrible (unreasonable?) is that by default a form is not resizable.
Here's a simple guide on how to make a userform drag and re-sizable.
http://www.mrexcel.com/forum/excel-questions/558649-userform-movable-resizable.html
Here is transcribed solution from
https://www.mrexcel.com/board/threads/resize-a-userform.485489/
I have tested it and it works
First add these declaration to your header
'Declaration for form resize
Private Declare Function GetActiveWindow Lib "user32.dll" () As Long
Private Declare Function SetLastError Lib "kernel32.dll" (ByVal dwErrCode As Long) As Long
Private Declare Function GetWindowLong Lib "user32.dll" Alias "GetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long) As Long
Private Declare Function SetWindowLong Lib "user32.dll" Alias "SetWindowLongA" (ByVal hWnd As Long, ByVal nIndex As Long, ByVal dwNewLong As Long) As Long
Add this sub to your form
Private Sub MakeFormResizable()
'Written: August 02, 2010
'Author: Leith Ross
'Summary: Makes the UserForm resizable by dragging one of the sides. Place a call
' to the macro MakeFormResizable in the UserForm'
'from https://www.mrexcel.com/board/threads/resize-a-userform.485489/
Dim lStyle As Long
Dim hWnd As Long
Dim RetVal
Const WS_THICKFRAME = &H40000
Const GWL_STYLE As Long = (-16)
hWnd = GetActiveWindow
'Get the basic window style
lStyle = GetWindowLong(hWnd, GWL_STYLE) Or WS_THICKFRAME
'Set the basic window styles
RetVal = SetWindowLong(hWnd, GWL_STYLE, lStyle)
'Clear any previous API error codes
SetLastError 0
'Did the style change?
If RetVal = 0 Then MsgBox "Unable to make UserForm Resizable."
End Sub
And finally call this sub from your Userform_Activate
Private Sub UserForm_Activate()
MakeFormResizable
End Sub
I am trying to automate data population on some excel sheets that have some macros. Now the excel is protected and I cannot get the secret key. Now I am able to run the macros but when I try to pass arguments I get arguments mismatch.
If I just run the macro with the name, I get an inputbox which takes an extra argument as input and auto generates some of the values for the columns. I have to manually enter this value into the inputbox as of now. Is there any way that I could automate that process, i.e capture the inputbox thrown by the macro in the vb.net script and enter the values from there? i.e., I would like to run the macro and after I get the popup asking me to enter some value, use the vb.net code to enter the value to that popup.
Here is what I have till now
Public Class Form1
Dim excelApp As New Excel.Application
Dim excelWorkbook As Excel.Workbook
Dim excelWorkSheet As Excel.Worksheet
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
excelWorkbook = excelApp.Workbooks.Open("D:/excelSheets/plan_management_data_templates_network.xls")
excelApp.Visible = True
excelWorkSheet = excelWorkbook.Sheets("Networks")
With excelWorkSheet
.Range("B7").Value = "AR"
End With
excelApp.Run("createNetworks")
// now here I would like to enter the value into the createNetworks Popup box
excelApp.Quit()
releaseObject(excelApp)
releaseObject(excelWorkbook)
End Sub
Macro definition
createNetworks()
//does so basic comparisons on existing populated fields
//if true prompts an inputbox and waits for user input.
This stall my vb.net script too from moving to the next line.
Like you and me, we both have names, similarly windows have handles(hWnd), Class etc. Once you know what that hWnd is, it is easier to interact with that window.
This is the screenshot of the InputBox
Logic:
Find the Handle of the InputBox using FindWindow and the caption of the Input Box which is Create Network IDs
Once that is found, find the handle of the Edit Box in that window using FindWindowEx
Once the handle of the Edit Box is found, simply use SendMessage to write to it.
In the below example we would be writing It is possible to Interact with InputBox from VB.Net to the Excel Inputbox.
Code:
Create a Form and add a button to it.
Paste this code
Imports System.Runtime.InteropServices
Imports System.Text
Public Class Form1
Private Declare Function FindWindow Lib "user32" Alias "FindWindowA" _
(ByVal lpClassName As String, ByVal lpWindowName As String) As Integer
Private Declare Function FindWindowEx Lib "user32" Alias "FindWindowExA" _
(ByVal hWnd1 As Integer, ByVal hWnd2 As Integer, ByVal lpsz1 As String, _
ByVal lpsz2 As String) As Integer
Private Declare Function SendMessage Lib "user32" Alias "SendMessageA" _
(ByVal hwnd As Integer, ByVal wMsg As Integer, ByVal wParam As Integer, _
ByVal lParam As String) As Integer
Const WM_SETTEXT = &HC
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Ret As Integer, ChildRet As Integer
'~~> String we want to write to Input Box
Dim sMsg As String = "It is possible to Interact with InputBox from VB.Net"
'~~> Get the handle of the "Input Box" Window
Ret = FindWindow(vbNullString, "Create Network IDs")
If Ret <> 0 Then
'MessageBox.Show("Input Box Window Found")
'~~> Get the handle of the Text Area "Window"
ChildRet = FindWindowEx(Ret, 0, "EDTBX", vbNullString)
'~~> Check if we found it or not
If ChildRet <> 0 Then
'MessageBox.Show("Text Area Window Found")
SendMess(sMsg, ChildRet)
End If
End If
End Sub
Sub SendMess(ByVal Message As String, ByVal hwnd As Long)
Call SendMessage(hwnd, WM_SETTEXT, False, Message)
End Sub
End Class
ScreenShot
When you run the code this is what you get
EDIT (Based on further request of automating the OK/Cancel in Chat)
AUTOMATING THE OK/CANCEL BUTTONS OF INPUTBOX
Ok here is an interesting fact.
You can call the InputBox function two ways in Excel
Sub Sample1()
Dim Ret
Ret = Application.InputBox("Called Via Application.InputBox", "Sample Title")
End Sub
and
Sub Sample2()
Dim Ret
Ret = InputBox("Called Via InputBox", "Sample Title")
End Sub
In your case the first way is used and unfortunately, The OK and CANCEL buttons do not have a handle so unfortunately, you will have to use SendKeys (Ouch!!!) to interact with it. Had you Inbutbox been generated via the second method then we could have automated the OK and CANCEL buttons easily :)
Additional Info:
Tested on Visual Studio 2010 Ultimate (64 bit) / Excel 2010 (32 bit)
Inspired by your question, I actually wrote a blog Article on how to interact with the OK button on InputBox.
Currently, I employ a method where I run a thread before the macro is called by the script. The thread checks if the inputbox has been called. If it is, it picks up the value from the location and using sendkeys, submits the box.
This is a rudimentary solution but I was hoping for a more elegant solution to this problem.
My solution Code:
Public Class Form1
Dim excelApp As New Excel.Application
Dim excelWorkbook As Excel.Workbook
Dim excelWorkSheet As Excel.Worksheet
Private Sub Button4_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button4.Click
excelWorkbook = excelApp.Workbooks.Open("D:/excelSheets/some_excel.xls")
excelApp.Visible = True
excelWorkSheet = excelWorkbook.Sheets("SheetName")
With excelWorkSheet
.Range("B7").Value = "Value"
End With
Dim trd = New Thread(Sub() Me.SendInputs("ValueForInputBox"))
trd.IsBackground = True
trd.Start()
excelApp.Run("macroName")
trd.Join()
releaseObject(trd)
excelApp.Quit()
releaseObject(excelApp)
releaseObject(excelWorkbook)
End Sub
Private Sub releaseObject(ByVal obj As Object)
Try
System.Runtime.InteropServices.Marshal.ReleaseComObject(obj)
obj = Nothing
Catch ex As Exception
obj = Nothing
Finally
GC.Collect()
End Try
End Sub
Private Sub SendInputs(ByVal noOfIds As String)
Thread.Sleep(100)
SendKeys.SendWait(noOfIds)
SendKeys.SendWait("{ENTER}")
SendKeys.SendWait("{ENTER}")
End Sub
I have an Excel VBA macro containing a form. I would like for VB.net to either hide the form or take control of it and click the "X" button or the custom "Exit" button.
Does anybody have experience with this?
Sendkeys are highly unreliable.
If you can automate the Excel from VB.Net the I would recommend that. If you are interested in automating Excel from VB.Net then see this.
If you don't want to automate but want to directly handle it then I would recommend using the FindWindow and Sendmessage API to get control of the form. See this Example.
Let's say that there is a userform in Excel which looks like this
Use this code form VB.Net
CODE:
Imports System.Runtime.InteropServices
Imports System.Text
Public Class Form1
<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function FindWindow( _
ByVal lpClassName As String, _
ByVal lpWindowName As String) As IntPtr
End Function
<DllImport("user32.dll", SetLastError:=True, CharSet:=CharSet.Auto)> _
Private Shared Function SendMessage(ByVal hWnd As IntPtr, _
ByVal Msg As UInteger, _
ByVal wParam As IntPtr, ByVal lParam As IntPtr) As Boolean
End Function
Private Const WM_CLOSE = &H10
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click
Dim Ret As Integer
'~~> Get the handle of the Excel Userform named "Example"
Ret = FindWindow(vbNullString, "Example")
'~~> If Found
If Ret <> 0 Then
'~~> Close the Window
SendMessage(Ret, WM_CLOSE, CLng(0), CLng(0))
End If
End Sub
End Class
