I am parsing an Excel workbook using RubyXL and discovered that workbook[0] returns the first worksheet regardless of whether it is hidden.
I would like to isolate the first visible worksheet by coding something like workbook[0].not_hidden.
How can this be done in RubyXL?
It turns out visibility is held in a parameter called #state, where a visible worksheet has #state = nil and a hidden worksheet has #state = 'hidden'.
So, to isolate the first visible worksheet:
worksheet = workbook.select{ |w| w.state.blank? }[0]
Or, to isolate the first hidden worksheet:
worksheet = workbook.select{ |w| w.state == 'hidden' }[0]

Background:
Entry is via a subform for adding/showing/linking images.
I do not want to store the image files within my DB, the image folder is separate. The DB will grow rather large in time.
I have created a click-control enabling a popup for user to browse and click on the imagePATH to be added in a Bound Textfield (called Bildadress, no not misspelled in My country, Grin ) in the subform.
See code below.
Then I add a new unbound Image-control and specify its Controlsource = the Textfield mentioned above.
For the firs image this works wonderful, but for the following the Image-control returns NULL (not show att all). The data in the Textfield updates as it should.
Will the 2nd stage only work in a 1:1 relationship OR can I (with your help) use VBA code to make this work?
OPTIMAL would be to get this to work and also a 2nd Bound Textfield just displaying the actual image file name. .
I hope someone out there have encountered this problem who also didnt want to use Attachment to store the files within the databae.
CODE:
Private Sub AddFilePath_Click()
Call Selectfile
End Sub
Public Function Selectfile() As String
Dim Fd As FileDialog
Set Fd = Application.FileDialog(msoFileDialogOpen)
With Fd
.AllowMultiSelect = False
.Title = "Välj önskad fil"
If .Show = True Then
Selectfile = .SelectedItems(1)
Me.Bildadress = Selectfile
Else
Exit Function
End If
End With
Set Fd = Nothing
End Function
If you use a bound textbox that holds the image-path then you can use
Me.Imagecontrol.Picture = Me.BoundTextControl.Value
to load the picture into an unbound image control. In your case that would be something like
If .Show = True Then
Me.Bildadress.value = .SelectedItems(1)
Me.Bild.Picture = Me.Bildadress.value
Else
It would be best to also load the respective picture in the OnCurrent Event.
Private Sub Form_Current()
Me.Bild.Picture = Me.Bildadress.value
End Sub
However, keep in mind that access is a one-file-database and you break that paradigm when using links to external files where the files would belong into the DB.
I need to change the tab color of excel sheets with a particular color...something like this using ruby scripting
Here is an equivalent Ruby code using stdlib WIN32OLE :
require 'win32ole'
# create an instance of the Excel application object
excel = WIN32OLE.new('Excel.Application')
# make Excel visible
excel.visible = true
# open the excel from the desired path
wb = excel.workbooks.open("C:\\Users\\test.xlsx")
#iterate through each worksheet and color the tab as you want
1.upto(3).each do |i|
# getting the worksheet
wbs = wb.worksheets(i)
#color it
wbs.tab.color = 255
end
output
Look documentation of Tab.Color property and Worksheet.Tab Property.
How do I find all cells containing a text value such as merchant_id and change the background color of those cells to a specific color?
This macro will use the current selected range and check each cell for merchant_id. Then mark it maroon if true. To pick a particular color, the best way is to record a macro and see what values it creates. Take those numbers and replace the contents of the With block
Sub MarkCellsInSelection()
For Each c In Selection
If c.Value = "merchant_id" Then
With c.Interior
.Pattern = xlSolid
.PatternColorIndex = xlAutomatic
.ThemeColor = xlThemeColorAccent2
.TintAndShade = 0.399975585192419
.PatternTintAndShade = 0
End With
End If
Next
End Sub
I have an Excel 2007 Worksheet with many buttons and labels that act as menu options (i.e. user clicks the buttons, labels with images) and is presented with forms, or some thing else.
These images / icons for the buttons and labels are loaded in VBA by assigning the Picture property of the Control and calling LoadPicture() method with the full image file path as parameter, like So.
With SomeFormObject
.cmdOpenFile.Picture = LoadPicture("F:\projectname\images\fileopen.BMP")
End With
This method of loading images for buttons, other controls is causing 2 issues.
1) It creates a dependency on the image files and physical location for every user, so if a user does not have the drive mapped and files present, the VBA fails with runtime error of file or path not found.
2)
The app gets very slow if the images are on a shared drive (which is the case)
I want to eliminate both issues and somehow load icons, images into control internally, without any external dependencies on external image files.
What is the best way to achieve this in Excel 2007 VBA?
I could not file any Visual Basic 6.0 / Visual Studio style "Resource File Editor" / feature with which to accomplish this.
Please advice! thank you

I really hope that there is a easier way to do this, but this is the only one I found:
The Idea is:
You keep the Pictures embedded in a Sheet and every time you want to set the pictures for the Command you export them from your worksheet to a file and load them through LoadPicture. The only way to export an embedded Picture through VBA that I found is by making it a Chart first.
The following code is based on 'Export pictures from Excel' from johnske
Option Explicit
Sub setAllPictures()
setPicture "Picture 18", "CommandButtonOpen"
setPicture "Picture 3", "CommandButtonClose"
End Sub
Sub setPicture(pictureName As String, commandName As String)
Dim pictureSheet As Worksheet
Dim targetSheet As Worksheet
Dim embeddedPicture As Picture
Dim pictureChart As Chart
Dim MyPicture As String
Dim PicWidth As Long
Dim PicHeight As Long
Set pictureSheet = Sheets("NameOfYourPictureSheet") ' <- to Change '
Set targetSheet = Sheets("NameOfYourSheet") ' <- to Change '
Set embeddedPicture = pictureSheet.Shapes(pictureName).OLEFormat.Object
With embeddedPicture
MyPicture = .Name
PicHeight = .ShapeRange.Height
PicWidth = .ShapeRange.Width
End With
Charts.Add
ActiveChart.Location Where:=xlLocationAsObject, Name:=pictureSheet.Name
Set pictureChart = ActiveChart
embeddedPicture.Border.LineStyle = 0
With pictureChart.Parent
.Width = PicWidth
.Height = PicHeight
End With
With pictureSheet
.Select
.Shapes(MyPicture).Copy
With pictureChart
.ChartArea.Select
.Paste
End With
.ChartObjects(1).Chart.Export Filename:="temp.jpg", FilterName:="jpg"
End With
pictureChart.Parent.Delete
Application.ScreenUpdating = True
targetSheet.Shapes(commandName).OLEFormat.Object.Object.Picture = LoadPicture("temp.jpg")
Set pictureChart = Nothing
Set embeddedPicture = Nothing
Set targetSheet = Nothing
Set pictureSheet = Nothing
End Sub
Sub listPictures()
' Helper Function to get the Names of the Picture-Shapes '
Dim pictureSheet As Worksheet
Dim sheetShape As Shape
Set pictureSheet = Sheets("NameOfYourSheet")
For Each sheetShape In pictureSheet.Shapes
If Left(sheetShape.Name, 7) = "Picture" Then Debug.Print sheetShape.Name
Next sheetShape
Set sheetShape = Nothing
Set pictureSheet = Nothing
End Sub
To Conclude:
Loading the Images from a Mapped Networked Drive seems less messy, and there shouldn't be that much of a speed difference.
2 alternatives i can think of: form.img.picture=pastepicture , and = oleobjects("ActiveXPictureName").object.picture.
i have written some Macros for Visio. Now I copied these to a Stencil called Macros.vss
How can I call my Macros now?
It all depends on what the macros do and how you'd like to call them. I'm going to assume they're simply macros that will execute something within the active Visio page.
By default in Visio VBA, any public subs with no arguments get added to the Visio Tools->Macros menu, in a folder named by the document holding the macros (in this case Macros) and then separated into folders by module name. If you're the only person using the macros then you probably don't need to do anything else.
However, since you put them in a vss file I'll assume you'd like to distribute them to other people.
There's something funny (and by funny I mean irritating) about Visio and how toolbars and buttons work, when added programmatically. Unfortunately, when you create a toolbar using the UIObject and Toolbar and ToolbarItem classes, Visio is going to assume the code you're calling resides in the active drawing, and cannot be in a stencil. So I can give you a little guidance on using those classes, but basically it consists of distributing a .vst template along with your .vss files, with just a single required sub in the .vst file.
So, instead of using a custom toolbar, you can attach code to shape masters in your .vss file that execute the code when they get dropped on a drawing document (using CALLTHIS and the EventDrop event in the shapesheet). With this method I just have a sub that gets called using callthis that takes a shape object as an argument, executes some code, then deletes the shape (if I don't want it around anymore).
And lastly, you can manipulate the Visio UI programmatically to add a toolbar and buttons for your macros. Below is some sample code, basically the way I do it with a solution I developed. As I mentioned above, the most important part of using this method is to have a document template (.vst) that holds a sub (with the below code it must be named RunStencilMacro) that takes a string as an argument. This string should be the "DocumentName.ModuleName.SubName". This sub must take the DocumentName out of the string, and get a Document object handle to that document. Then it must do ExecuteLine on that document with the ModuleName.SubName portion. You'll have to step through the code and figure some things out, but once you get the hang of what's going on it should make sense.
I'm not sure of any other ways to execute the macros interactively with VBA. I think exe and COM addons may not have this issue with toolbars...
