How to Compress Pictures in Excel using VBA

How to Programatically Compress Pictures/Images in Excel using VBA

If you are trying to compress pictures, you will normally be doing using the following dialog:

Compress Pictures Excel Dialog

Compress Pictures Excel Dialog



The same dialog can be automated using Excel VBA and SendKeys as shown below:

Sub Compress_PIX()

Dim octl As CommandBarControl

With Selection
    Set octl = Application.CommandBars.FindControl(ID:=6382)
    Application.SendKeys "%e~"
    Application.SendKeys "%a~"
     octl.Execute
End With

End Sub 

Supressing "Compressing Pictures May reduce the quality of your images.." dialog is also taken care by SendKeys

The code uses CommandBarControl to find the Command and then execute the dialog

How to add description to Macro Functions in Excel VBA

How to add argument description to Macros/User Defined Functions in Excel VBA

User-defined functions are created in Excel for helping the Excel users. It would be good to add descriptions of the arguments used in the functions. This can be done using Application.Macrooptions method

Let us assume a small User Defined Function that takes an argument:

Function A_Sample_UDF(ByVal sArg)

MsgBox "Sample UDF " & sArg

End Function

The following code will add the UDF to information category

Sub Add_UDF()

Dim ArgDes As Variant

ArgDes = Array("First Arg")

Application.MacroOptions Macro:="Personal.XLSB!A_Sample_UDF", Description:="Sample Function", Category:="Information", ArgumentDescriptions:=ArgDes

End Sub

How to Save Word Document as WebPage using VBA

I have some lazy friends who come up with strange requirements. One such guy wanted me to extract images from Word document into a separate folder, which he want to use later. I found that saving the Webpage creates the images in a folder and that would be enough for the sloth friend. Here is the code snippet of that.

This code Saves the given document in Temporary folder (See How to get Temp folder using VBA)

Then it deletes the file and folder from the location (See Different Ways to Delete Files in VBA) to be sure there is no clash.

It then saves the document and loops through the Images folder using Dir function (See Dir Function in VBA) and stores them in an array

Function Save_As_HTML(ByRef oTempWd As Document) As Boolean


Dim sDir
Dim iDir As Integer
Dim oShp As Word.Shape                      ' Word Shape Object

On Error GoTo Err_Save_As_HTML

sTempFolder = GetTempFolder()
sImageFolder = sTempFolder & "Save_As_HTML_files\"

Delete_File sTempFolder & "Save_As_HTML.html"
Delete_File sImageFolder & "*.*"
RmDir sImageFolder


oTempWd.SaveAs sTempFolder & "Save_As_HTML.html", FileFormat:= _
        wdFormatHTML, LockComments:=False, Password:="", AddToRecentFiles:=True, _
        WritePassword:="", ReadOnlyRecommended:=False, EmbedTrueTypeFonts:=False, _
         SaveNativePictureFormat:=False, SaveFormsData:=False, SaveAsAOCELetter:= _
        False


oTempWd.Close (False)
Erase arImageFiles

sDir = Dir(sImageFolder & "*.gif") ' You can also use PNG format
Do Until Len(sDir) = 0
    iDir = iDir + 1
    arImageFiles(iDir) = sDir
    sDir = Dir
Loop

Err_Save_As_HTML:
If Err <> 0 Then
   Debug.Assert Err = 0
   Debug.Print Err.Description
   Err.Clear
   Resume Next
End If

End Function

How to Check Internet Connectivity using VBA

The following code snippet uses API functions to check Internet connectivity and also the type of connection
:

Public Declare Function InternetGetConnectedState _
                         Lib "wininet.dll" (lpdwFlags As Long, _
                                            ByVal dwReserved As Long) As Boolean

Private Declare Function InternetGetConnectedStateEx Lib "wininet.dll" Alias "InternetGetConnectedStateExA" ( _
ByRef lpdwFlags As Long, _
ByVal lpszConnectionName As String, _
ByVal dwNameLen As Long, _
ByVal dwReserved As Long) As Long


'Local system uses a modem to connect to the Internet.
Private Const INTERNET_CONNECTION_MODEM As Long = &H1

'Local system uses a LAN to connect to the Internet.
Private Const INTERNET_CONNECTION_LAN As Long = &H2

'Local system uses a proxy server to connect to the Internet.
Private Const INTERNET_CONNECTION_PROXY As Long = &H4

The following API functions are used

Function IsConnected() As Boolean
    
    Dim Stat As Long
    
    IsConnected = (InternetGetConnectedState(Stat, 0&) <> 0)
    
    If IsConnected And INTERNET_CONNECTION_LAN Then
        MsgBox "Lan Connection"
    ElseIf IsConnected And INTERNET_CONNECTION_MODEM Then
        MsgBox "Modem Connection"
    ElseIf IsConnected And INTERNET_CONNECTION_PROXY Then
        MsgBox "Proxy"
    End If
End Function

If you want to know just if it is connected or not you can use the following:

CBool(InternetGetConnectedStateEx(0, vbNullString, 512, 0&))

How to Dynamically Change Userform's Control properties from Excel Sheet using Excel VBA

How to Draw Rectangle in VBA using Excel Data

This is an exclusive request from Phil. If you find it interesting, I am more glad. The idea is to draw/resize a rectangle in userform based on values from Excel sheet.

I am using a label control for rectangle. Let us add a label control to userform and name it as LabelRect

To the WorkSheet_Change event of the required sheet add the following event

Private Sub Worksheet_Change(ByVal Target As Range)

Dim oLbl As MSForms.Label

Set oLbl = UserForm1.LabelRect

If Target.Address = "$B$1" Or Target.Address = "$B$2" Then

    If IsNumeric(Range("B1").Value) = True Then oLbl.Height = Range("B1").Value
    If IsNumeric(Range("B2").Value) = True Then oLbl.Width = Range("B2").Value
    oLbl.BackColor = vbGreen
    
    UserForm1.Show (False)
    
End If

End Sub

The code will get executed when there is a change in Value in column B1 and B2. Hence the label in the userform will be adjusted accordingly as shown below:

We have the Excel macros embedded in a workbook (CanBeDeleted.xlsm)

Sub AnotherWrkBook_Macro()

MsgBox "I have Run!"


End Sub

Above code is a simple message box. The code below, however, accepts an argument and stores the same in the workbook

Function Store_Value(ByVal sPPTName As String)

Sheet1.Range("A2").Value = sPPTName


End Function

The following Powerpoint VBA code uses Application.Run method of Excel VBA to execute a particular macro.

Multiple arguments can be passed to Application.Run method

Sub Run_Excel_Macro_From_PPT()

Dim oXL As Excel.Application            ' Excel Application Object
Dim oWB As Excel.Workbook               ' Excel Workbook Object
Dim sPName As String                    ' Variable - Active Presentation Name

On Error GoTo Err_PPXL

' -----------------------------------------------------------
' coded by Shasur for http://vbadud.blogspot.com
' -----------------------------------------------------------

Set oXL = New Excel.Application
Set oWB = oXL.Workbooks.Open("C:\Users\comp\Documents\CanBeDeleted.xlsm")

' Set Excel as Visibile - Turn Off if not needed
oXL.Visible = True

' Pass and Argument
sPName = ActivePresentation.Name

' Run the Macro without Argument
oXL.Application.Run "'CanBeDeleted.xlsm'!AnotherWrkBook_Macro"

' Run the Macro without Argument
oXL.Application.Run "'CanBeDeleted.xlsm'!Store_Value", sPName

' Save and Close the Workbook
oWB.Save
oWB.Close (False)


' Quit the Excel
oXL.Quit


' Release Objects - Good Practive
If Not oWB Is Nothing Then Set oWB = Nothing
If Not oXL Is Nothing Then Set oXL = Nothing


Err_PPXL:
If Err <> 0 Then
    MsgBox Err.Description
    Err.Clear
End If
End Sub

The macro saves and closes the workbook and quits Excel
