What i want :
to a make a button that exports the selected data in this FelxGrid into .ini file format take (heights) as section and the others as values and keys , it dosen't have to be ini format it can also be something close to it
What i tried so far
Private Sub commandbutton_1()
Dim configfile As String
Dim myArray() As String 'i tried using arry but it didn't work
configfile = "C:\" & "\CONFIGMEEE!.INI"
PutINISetting "", "", SettingsGrid.Clip, configfile
MsgBox "Exported.", vbInformation, "Settings"
SettingsGrid.SaveGrid configfile, flexFileTabText
What happened then
the data we exported but not formatted at all as ini and written so :
Important to know
The flexgrid iam using is a vsflexgrid not an msflexgrid
And i am also using this as a MOUDLE

I have a base64 string which was generated from an image using another application. Now on my application I want to convert the base64 string to byte and display it on a PictureBox.
I already found a sample application which takes a byte input and sets a PictureBox image. Unfortunately the sample application gets the byte array from an image and just translates it back. Here's the function it uses.
Public Function PictureFromByteStream(b() As Byte) As IPicture
Dim LowerBound As Long
Dim ByteCount As Long
Dim hMem As Long
Dim lpMem As Long
Dim IID_IPicture(15)
Dim istm As stdole.IUnknown
On Error GoTo Err_Init
If UBound(b, 1) < 0 Then
Exit Function
End If
LowerBound = LBound(b)
ByteCount = (UBound(b) - LowerBound) + 1
hMem = GlobalAlloc(&H2, ByteCount)
If hMem <> 0 Then
lpMem = GlobalLock(hMem)
If lpMem <> 0 Then
MoveMemory ByVal lpMem, b(LowerBound), ByteCount
Call GlobalUnlock(hMem)
If CreateStreamOnHGlobal(hMem, 1, istm) = 0 Then
If CLSIDFromString(StrPtr("{7BF80980-BF32-101A-8BBB-00AA00300CAB}"), IID_IPicture(0)) = 0 Then
Call OleLoadPicture(ByVal ObjPtr(istm), ByteCount, 0, IID_IPicture(0), PictureFromByteStream)
End If
End If
End If
End If
Exit Function
Err_Init:
If Err.Number = 9 Then
'Uninitialized array
MsgBox "You must pass a non-empty byte array to this function!"
Else
MsgBox Err.Number & " - " & Err.Description
End If
End Function
Here's the function I found to convert a base64 string to a byte, it seems to be converting it but when I pass the byte data to the above function, no image appears.
Private Function DecodeBase64(ByVal strData As String) As Byte()
Dim objXML As MSXML2.DOMDocument
Dim objNode As MSXML2.IXMLDOMElement
' help from MSXML
Set objXML = New MSXML2.DOMDocument
Set objNode = objXML.createElement("b64")
objNode.dataType = "bin.base64"
objNode.Text = strData
DecodeBase64 = objNode.nodeTypedValue
' thanks, bye
Set objNode = Nothing
Set objXML = Nothing
End Function
And here's my code calling the functions.
Dim b() As Byte
b = DecodeBase64(Text1.Text)
Dim pic As StdPicture
Set pic = PictureFromByteStream(b)
Set Picture1.Picture = pic
Try this:

I am trying to save an image from a webpage using excel vba.
I'm managed to get the string (although not the one I want), and need to save it to disk.
The HTML code for the source is:
<img id="SkuPageMainImg" data-sku="491215" alt="Papir ubleket kraft 60g 40cm 5kg/rull" class="skuImageSTD" src="/content/images/product/491215_1_xnm.jpg?v=4TWLBni1V4k8GV8B_0P-GA" data-zoomimage="//www.staples.no/content/images/product/491215_1_xnl.jpg" data-resizeimage="{"0to1024":"/content/images/product/491215_1_xnm.jpg?v=4TWLBni1V4k8GV8B_0P-GA","1025to1450":"//www.staples.no/content/images/product/491215_1"}" data-screensize="">
My code is: IMG = .document.getElementById("SkuPageMainImg").src
This code captures the url after the src= :
/content/images/product/491215_1_xnm.jpg?v=4TWLBni1V4k8GV8B_0P-GA"
This will do, but what i would preffer to catch is the url after data-zoomimage= :
"//www.staples.no/content/images/product/491215_1_xnl.jpg"
Either way, what I am looking to accomplish is having Excel VBA save the image to a file on my disk - typically c:\folder\image_name.jpg
Anybody know the code to do this?
Import the URLDownloadToFile function and use it directly. The following is an entire module code sheet, including the declarations section at the top. The routine expects a list of the full img src URLs in column A starting at row 2. e.g.: http://www.staples.no/content/images/product/491215_1_xnm.jpg

I have a .ini file setup from which I read connection strings. I have a modeule to read the strings:
Option Explicit
Private Declare Function GetPrivateProfileString Lib "kernel32" _
Alias "GetPrivateProfileStringA" (ByVal lpApplicationName As String, ByVal lpKeyName As Any _
, ByVal lpDefault As String, ByVal lpReturnedString As String, ByVal nSize As Long _
, ByVal lpFileName As String) As Long
Public Const iniPath = "\DBSettings.INI"
Public Sub Main()
Dim dbPath As String
Dim dbPath As String
dbPath = GetSetting("DataBase", "DBPath")
dbPath= GetSetting("DataBase", "DBPath")
Form1.Show
End Sub
Private Function GetSetting(ByVal pHeading As String, ByVal pKey As String) As String
Const cparmLen = 100
Dim sReturn As String * cparmLen
Dim sDefault As String * cparmLen
Dim aLength As Long
aLength = GetPrivateProfileString(pHeading, pKey _
, sDefault, sReturn, cparmLen, App.Path & iniPath)
GetSetting = Mid(sReturn, 1, aLength)
End Function
Now, I am trying to display the strings on click of a button:
Option Explicit
Public Sub Command1_Click()
MsgBox (dbPath)
MsgBox (dbPath)
End Sub
However, it seems the form cannot see the variables in the module. How may I fix this?
Any help would be appreciated.
dbPath is declared in a sub so scoping rules state that the variable only exists within that sub.
To make a variable visible everywhere declare it in a module with the public access modifier:
public dbPath as string
And remove the dim in main()
DBPath is a Procedure Scope variable, as it is declared inside a Procedure (Sub Main()).
It will not be visible from other modules, or even the module itself.
And also, you cannot declare a Public variable inside a Procedure (Sub or Function).

I have a xls/csv list of images:
Name image url
test.jpg http://test.com/232dd.jpg
test2.jpg http://test.com/2390j.jpg
I have about 200 of these...is there a way to download the list and name them as identified in the xls file?
Here is my Excel VBA:
Private Declare Function URLDownloadToFile Lib "urlmon" _
Alias "URLDownloadToFileA" (ByVal pCaller As Long, _
ByVal szURL As String, ByVal szFileName As String, _
ByVal dwReserved As Long, ByVal lpfnCB As Long) As Long
Private Sub download_pics()
Dim rng As Range
Dim cell As Variant
Set rng = Range("A1:B10")
For Each cell In rng
' Download the file.
URLDownloadToFile 0, cell(rng, 2).Value, "C:\" & cell(rng, 1).Value, 0, 0
Next
End Sub
Running into type mismatch error with URLDownloadToFile
OK The type mismatch has to do with your iteration. You need to specify how you're iterating over rng with the For each cell in rng statement, like:
For each cell in rng.Rows
Otherwise, it treats that statement as For each cell in rng.Cells and that raises the mismatch error.
I made some modifications to the code (based on Sid's answer here), so it checks to ensure the file downloaded successfully, but mostly what you found was correct, you just need to implement it a little differently.
Private Declare Function URLDownloadToFile Lib "urlmon" _
