Setting cell value using TCOM/TCL with function call - excel

I'm trying to assign the cell values in TCOM using function call. But i See the exact function name getting printed.
set application [::tcom::ref createobject "Excel.Application"]
set workbooks [$application Workbooks]
$application DisplayAlerts False
set workbook [$workbooks Open "\\$filename.csv"]
set worksheets [$workbook Worksheets]
set worksheet [$worksheets Item [expr 1]]
set cells_worksheet1 [$worksheet Cells]
$cells_worksheet1 Item 27 B $Attribute
I want to replace $cells_worksheet1 Item 27 B $Attribute to $cells_worksheet1 Item 27 B {[getAttribute]} where getAttribute function returns $attribute. Any idea how to do this?

As far as I can see from the Excel API, you get a Range back from the Cells property, and a further Range back from its Item member. You can then access the properties of that individual item using the property accessors.
# Assuming your largely-perfect code from your question...
set cell [$cells_worksheet1 Item 27 B]
set orientation [$cell Orientation] ;# Arbitrary example of getting a property
$cell Orientation 42 ;# Setting the property
You can get the name of the property to manipulate from sources other than literals:
proc getAttribute {} {
return "Orientation"
}
puts "orientation is [$cell [getAttribute]]" ;# Note, *no* {braces} involved!
That won't necessarily work well for all properties though; the problem isn't that you can't ask for them, but rather some want additional information passing in when you fetch them and others take extra work to extract once fetched as they are compound objects themselves. It's hard to give better advice without knowing exactly what you're planning to do with it.
The issue with the braces was that Tcl treats them as being exact substitution-free literals. That's great when you're declaring a procedure, but not so useful when you want to call that procedure and use the results.

Can you group shapes as they are created in Excel?

I have a userform in Excel 2016 that will generate a certain group of shapes (a welding symbol, if the context is helpful), mainly consisting of lines, arcs, and textboxes. Some of these will be the same every time the code is run, while others are options to be determined by the user via the userform. At the end those elements are grouped into a single symbol. My current code works as described thus far.
The problem comes when I try to run the form a second time (generating a second group of shapes independent of the first group). I have it set up such that as the code is executed, it creates a shape, names that shape appropriately, then groups all shapes at the end, referring to them by name. The second time the code is run, it uses the same names as in the first run. As soon as it tries to form the second group, I get an error due to names referring to two different shapes.
My question is this: Is there a way to add shapes to a group (or to a collection to be grouped later) as they are created? It seems naming shapes isn't the way to go, as the names are retained after the code ends. I tried referencing by shape index, but since I have images on the page as well, it's hard to determine exactly what a particular shape's index is. I apologize for the lack of code, as I don't have access to it right now. If needed I can write up something simple to get the point across. Any help is greatly appreciated!
You can group shapes with a command like this:
Dim ws as Worksheet
Set ws = ActiveSheet ' <-- Set to the worksheet you are working on
ws.Shapes.Range(Array("Heart 1", "Sun 2", "Star 3")).Group
(you can access the shapes via name or via index). The result of the group command is another shape that is added to the sheet. But be aware that the grouped shapes still exists in the sheet, you can access them with the GroupItems-property.
With ws.Shapes
Dim shGroup As Shape, sh As Shape
Set shGroup = .Range(Array("Heart 1", "Sun 2", "Star 3")).Group
shGroup.Name = "MyNewGroup" & .Count
For Each sh In shGroup.GroupItems
Debug.Print sh.Name, sh.Type
Next sh
End With
As you can see, the single shape elements don't change their names, so grouping would not solve your naming issue. The only way is to add a suffix to the name, e.g. a number (as Excel does it when it creates a shape).
Update: Of course the Array- parameter does not need to be static. You can declare an array that is large enough (it doesn't matter if it contains some empty elements).
Const maxShapes = 12
Dim myShapes(1 to maxShapes) as String
myShapes(1) = *Name of first shape you created*
myShapes(2) = *Name of second shape you created*
...
ws.Shapes.Range(myShapes).Group
or use the Redim command:
Dim myShapes() as String
Redim myShapes(1 to NumberOfShapesInYourNewGroup)
myShapes(1) = *Name of first shape you created*
myShapes(2) = *Name of second shape you created*
...
ws.Shapes.Range(myShapes).Group
To get a unique shape and group name, you can implement various methods. I don't like the attempt with a global variable as they might get reset - for example when you cancel execution during debugging. You could use for example the suffix that Excel generates when you create a new shape. Or put the rename-statement into a loop, put a On error Resume Next before the rename (and don't forget to put an On error Goto 0 after it) and loop until renaming was successfull. Or loop over all shapes in your sheet to find the next free name.
After some trial and error, the solution I came up with is something like the following.
'Count shapes already on sheet
Shapesbefore=ActiveSheet.Shapes.Count
'Create new shapes
'Create array containing indexes of recently created shapes
Dim shparr() As Variant
Dim shprng As ShapeRange
ReDim shparr(Shapestart + 1 To ActiveSheet.Shapes.Count)
For i = LBound(shparr) To UBound(shparr)
shparr(i) = i
Next i
'Group shapes and format weight/color
Set shprng = ActiveSheet.Shapes.Range(shparr)
With shprng
.Group
.Line.Weight = 2
.Line.ForeColor.RGB = 0
End With
This way I don't have to worry about creating and managing various group and shape names, as I don't need to go back and reference them later.

VBA Populate Different Objects Using the Value from a Sub Argument

Good Afternoon All,
Let me preface this post by saying I have very little experience using VBA, but it is the tool I have to work with in this instance, so here I am. I am using the SAS Add-In for Microsoft Office, which isn't entirely relevant in this situation as far as I can tell, but it is best to give you some context. I have 2 subs that function very differently but make use of the same named ranges.
The first sub uses values from 4 cells within Excel and submits them to a stored process which returns values to particular cells which are defined as named ranges - approximately 64. Once that takes place the end-user will validate the results, make some changes to the values in the 64 cells and then submit the second sub. The second sub then passes the values contained within the 64 cells for processing by a second stored process.
It makes more sense to me to have the 64 variables defined once and not multiple times to save on maintenance, but they are applied to different objects for example:
Sub1
Dim outputParams As SASRanges
Set outputParams = New SASRanges
Dim DD_BD_Age As Range
Set DD_BD_Age = Sheet1.Range("DD_BD_Age")
outputParams.Add "DD_BD_AGE", DD_BD_Age
Sub2
Dim prompts As SASPrompts
Set prompts = sas.CreateSASPromptsObject
Dim DD_BD_Age As Range
Set DD_BD_Age = Sheet1.Range("DD_BD_Age")
prompts.Add "DD_BD_AGE", DD_BD_Age
Is there any way that I can define these variables for use across either sub. If I was using SAS I would create a macro with a parameter which would allow me to specify the value of outputParams or prompts depending on the context in which I was using them.
Admittedly, with my limited experience with VBA, I may just be making things more difficult than they need to be, so please let me know if this is the case.
Any help would be greatly appreciated.
If your SAS objects have a common "Add" method then you can do something like this:
Dim outputParams As SASRanges
Set outputParams = New SASRanges
AddParams outputParams
Dim prompts As SASPrompts
Set prompts = sas.CreateSASPromptsObject
AddParams prompts
'add common parameters
Sub AddParams(obj As Object)
With obj
.Add "DD_BD_AGE", Sheet1.Range("DD_BD_Age")
'etc for the rest
End With
End Sub

MS Access: Choosing Worksheet from Excel Workbook

I'm writing some code in MS Access and I reached to the point where user needs to choose on which worksheet of an Excel workbook there need to be performed some operation. I don't know, what name of this worksheet is or on which position it is placed.
I was thinking about a solution which will show user a form (as modal form) with listbox containing all sheets names'. When user click one of them form will show aside A1:J10 range (so user can choose the right one worksheet). After confirming choosen worksheet it will return as worksheet object.
Every thing was great untill I wanted to pass a object variable to the form. In openArgs I can only pass a string. I was even thinking about a class which will open this form but it's still no luck with passing object parameter.
I'm trying to avoid global/public variables.
Any ideas?
Assuming your object is wsObj, can't you just use wsObj.Name ?
Also have a look at wsObj.CodeName, which may be interesting as well.
There are many possibilities to send some value between objects.
A) Using Global vars into ACCESS Vba module
Global yourvariable As String
if you need some different value can use Variant, Single, etc.
B) Using Windows Register
To save value:
SaveSetting "yourprojectname", "Settings", "yourvariable", yourvalue
To retrieve value:
retvalue = GetSetting("yourprojectname", "Settings", "yourvariable", "your_default_value_if_not_exist")
C) Using OpenArg into Open Form command procedure
DoCmd.OpenForm "stDocName", acNormal, "filter_if_needed", "stlinkcriteria", acFormEdit, acWindowNormal, "arguments_forOpenArgs"
On destination form
Private Sub Form_Open(cancel as integer)
your_args=Me.OpenArgs
On all three possible solutions you can send more than one value using a chain with vars and values, an example:
myvar_mutiple="name=John Doe|address=Rua del Percebe 34|location=Madrid|phone=34 91 1234567"
On this example i used "pipe" (AltGr on key 1) char to separate each var=value
Then on destination procedure only need split each pair:
splitvar=Split(myvar_multiple,"|")
With this you obtain for each "splitvar" an element like "name=John Doe"
Do again an split with "=" to obtain variable an value. For each value you can reassign the result to a local vars.
Full code example:
if me.OpenArgs<>"" then
splitvar=Split(me.OpenArgs,"|")
for x=0 to ubound(splitvar)
tmpsplit=Split(splitvar(x),"=")
paramvars=tmpsplit(0)
paramvalue=tmpsplit(1)
select case paramvars
case "name"
stname=paramvalue
case "address"
straddress=paramvalue
case "location"
strlocation=paramvalue
case "phone"
strphone=paramvalue
end select
next
end if
Some recommendations that i use for this code "multiple vars":
- always use Low Case variable or change this:
paramvars=tmpsplit(0)
by
paramvars=lcase(tmpsplit(0))
-if you need to use "=" into value you can change by other alternative char or search the first "=" form left (i used this solution instead Split)
paramvars=trim(lcase(left(splitvar(x),len(splitvar(x))-(len(splitvar(x))-instr(splitvar(x),"="))-1)))
remember that you can send any value and can be converted on destination code. On this sample i use only String so you can use cLng or cInt etc.
Over your solution to select Sheet on excel from Access i think there are better alternatives.
IN the forms Module you can declare a property as object and then set that property once loaded. So in the form module
Option Explicit
Private myObj as object
Property Set DesiredWorksheet(o as object)
set myobj = o
End
and then in your code
Load myform
set myform.desiredworksheet = wsObj
myform.show
Ahh, sorry I was writing Excel not Access!!!
Docmd.openform f
f.desiredworksheet = ws.obj
docmd.openform f, windowmode:=acdialog
ought to work

How can I delete an object which is the subject of a loop?

The problem I have is that the user is copying from one content control and pasting it into another accidentally. When extracting the data from this form, it then picks up that extra CC and therefore the value twice over.
When pulling the data I'm trying to see if a CC has a ParentCC and then delete it, but I keep getting
Run time error 5825: Object has been deleted.
I can understand why but I'm unsure as to how get around it, nothing I've searched seems to work.
'With Word document Statement precedes this
For Each CCtrl In .ContentControls
CCtrlText = CCtrl.Range.Text
If Not CCtrl.ParentContentControl Is Nothing Then
CCtrl.ParentContentControl.Range.Text = CCtrlText
CCtrl.Delete
End If
Next
How can I remove this content control which is duplicated inside the other and retain the input information?
So after some messing around and looking into how the local variables properties changed as a stepped through the code I have found that the line:
CCtrl.ParentContentControl.Range.Text = CCtrlText
Was in effect replacing the Content Control (CC) in it's ParentCC range property with the input text, and therefore deleting the duplicated CC.
CCtrl.Delete was trying to delete an object that had already been deleted and that swhy it was throwing an error.
I think with a foreach loop you can't alter the contents of the list/array without impacting the function of the loop. If you instead use the indexers, it should allow you to alter the collection, since you are not impacting the loop (number to number):
Dim i As Integer
Dim c As ContentControl
For i = 1 To d.ContentControls.Count
Set c = d.ContentControls(i)
c.Delete
Next i

Excel Interop - Getting type of Excel::Application::Selection

When something is selected in Excel, the Excel::Application::Selection property contains the selected object. For e.g. if I select some cell, I can easily cast them to Excel::Range using:
Excel.Range cells = Excel.Application.Selection as Excel.Range
Where Excel = Microsoft.Office.Interop.Excel
Now when some picture is selected, I have to cast it to Excel::Picture, then Excel::Shape in case of some shapes but it seems there are different interfaces for each shape like Oval, Rectangle etc. I need to delete whatever thing is selected on the worksheet. If its a cell, then the contents will be cleared, a Picture,Shape or OLEObject will be deleted but the problem is that I do not want to check each and every interface:
if (null != ThisApplication.Selection as Excel.Shape)
(ThisApplication.Selection as Excel.Shape).Delete();
else if (null != ThisApplication.Selection as Excel.Picture)
(ThisApplication.Selection as Excel.Picture).Delete();
else if (null != ThisApplication.Selection as Excel.OLEObject)
(ThisApplication.Selection as Excel.OLEObject).Delete();
I wish if there is just one base interface to which I can cast all the Shapes/Pictures and call delete on them.
Is it possible to get:
The real type inside Application::Selection - it displays a System::COMObject but no info on the real type
Somehow identify that Selection contains a picture/shape etc and call the "Delete" method on the underlying type
This is how I solved my problem. The answer is to use the late binding in VBA. We call a VBA macro from within our C# addin using the Application.Run(...) method. The VBA macro just executes the following code:
Application.Selection.Delete
and VBA calls the Delete method on whatever shape it is.
