If I have a collection of forms (myForms) and I want to switch the position of two forms in the collection (say items 3 and 4 for example), I would expect that the following code would work:
Dim temp as Form
Set temp = myForms(3)
Set myForms(3) = myForms(4)
Set myForms(4) = temp
But that doesn't work. It fails at the third line with the error "Controls property is read only." If I change the line to:
myForms(3) = myForms(4)
I get a type mismatch error instead.
If myForms is a standard collection:
Dim myForms as New Collection
(which is actually different from the controls collection) and you've added the forms using:
myForms.Add frmOne, myForms.Add frmTwo
etc then (yes) you do need to use the Add and Remove methods because of the way the collection references the added objects.
Otherwise the interpretation is that you actually want to replace one form with another and this is not allowed. You can't say:
Set frmOne = frmTwo
unless these are actually variables of type Form.
Why do you need to switch the order? Are you referencing the item numbers somewhere? Would using a Dictionary to collect the forms and reference them by a key be useful?
PS. The type mismatch is simply because both items are objects and need to be 'Set'.
You can't actually swap around items in the controls collection in VB6. You need to use the Add and Remove functions associated with each. Check out this article:

Hope this helps!

My task is to check the value of data from the global data sheet within different UIs, each of them having lots of data.
My idea was to do this in a generic way.
I create a array with the objects name, which corresponds with the name of the data sheet column
And then I just compare the content
Browser("").Page("").GENERIC_TYPE(label).GetROProperty("value") = datasheet.GetParameter(label)
Is there such a Generic Type that works for WebEdit and WebList?
You can use WebElement and this is generic as all elements on the page are web elements.
If you are reading the objects from OR, then you might have to update the element type to WebElement and it's tidious (if you are dealing with multiple objects). So the alternative way is using the below approach.
Browser("").Page("").WebElement("xpath:=//*[#common_attribute=" + element_attribute_value + "]").GetROProperty("value") = datasheet.GetParameter(label)
The collection has something common with Dictionary in VBScript, but they are not the same thing.
Collection is object such as Session.Contents property.
Dictionary is an object created using the following code.
Dim dictObj
Set dictObj = CreateObject("Scripting.Dictionary")
I want to find the differences and commons with these two type objects, in order to know how to use them.
I have found these useful articles, but still not clearly understand what a collection really is in asp using VBScript.
Working with Collections
Using the Dictionary Class in VBA
My questions are:
Is there no Collection data type in VBScript? you can create a dictionary but you can not create a collection object.
When loop through the collection using For Each, what is the x is, the key of collection or the collection item value?
for each x in Session.Contents
Why can you use collection this way?
Session("FirstName")
is the same as
Session.Contents("FirstName")
What is the documentation of collection object?
The documentation of dictionary I can find is this
I may have misunderstood collection object, I so please tell me. Thank you so much.
Is there no Collection data type in VBScript?
Correct. There is no built-in Collection data type. It exists in VB, but VBScript does not have it. You can work with collections on existing objects in VBS, but you can't create new ones. Use the Scripting.Dictionary, which offers the same features.
When loop through the collection using For Each, what is the x, the key of collection or the collection item value?
For Each loops always give you the key on collection-like objects. You can then use the key to access the value. (If it gave you the value instead, there would be no way to get to the key in a for-each loop, i.e. you would have no idea what the value means.)
Dim key, val
For Each key In Session.Contents
val = Session(key)
Response.Write Server.HtmlEncode(key) & " = " & Server.HtmlEncode(val) & "<br>"
Next
Why can you use collection this way?
Session("FirstName")
Because the default property of the Session object is the Contents collection. And the default property of the collection objects is Item.
The default property is the one that gets called when you don't name a property in your code but still use parentheses on an object.
Therefore these are the effectively the same:
Session("FirstName") = "Foo"
Response.Write( Session("FirstName") & "<br>" )
Session.Contents("FirstName") = "Bar"
Response.Write( Session.Contents("FirstName") & "<br>" )
Session.Contents.Item("FirstName") = "Baz"
Response.Write( Session.Contents.Item("FirstName") & "<br>" )
Where the last variant is what actually happens while the other two variants are syntactic sugar. The Session.Contents collection is based on a regular collection, but has some added magic. For example, accessing missing keys does not throw an error.
What is the documentation of collection object?
Microsoft did a great job at not only abandoning the VB 6.0 documentation, but also making whatever remains of it impossible to find. The closest thing is the documentation of the Collection Object in Office VBA.
Otherwise there is the documentation of the IIS Session object, which applies to classic ASP. Related: Storing and Removing Data from the ASP Session Object.
I have a script in which I filter the data in a module by a certain attribute value. When I then loop through these objects, for now, I am displaying the absolute number of the objects in an infoBox. However, the script is displaying absolute numbers of objects that are not in the dataset. Upon further investigation, I found that the extra absolute numbers were for each table within the entire module. I can't figure out why the script would include these tables when they are not in the filtered module data. I have even tried manually filtering the module on this attribute value then use the "Tools -> Edit DXL" to loop through the resulting items and it still displays the numbers for the tables that are not included. Why would it do this?
Here's my code:
bm2 = moduleVar
Filter fltr = contains(attribute "RCR_numbers", sRCRNum, false);
filtering on;
set(bm2, fltr);
for oObj in document(bm2) do {
absNum = oObj."Absolute Number";
infoBox("Object #" absNum ".");
}
I have also tried removing the document cast so it says "for oObj in bm2 do" instead, but this doesn't change the output. Why is the code giving me objects that are not in the filter? Any help would be greatly appreciated since this is a high priority issue for my project and I'm out of ideas myself.

In the DOORS 9.6.1 DXL Reference Manual you can see that:
for object in document
Assigns the variable o to be each successive
object in module. It is equivalent to the for object in module loop,
except that it includes table header objects, but not the row header
objects nor cells.
So, you must either use for object in module or, within your existing loop, test the hidden attribute TableType - this will be set to TableNone for anything that is not part of a table, table headers included.
There is something I don't understand how to do with Gtkmm 3.
I have a custom business type that I have declared like this:
enum class Eurocents : int {};
I would like to render this type into a Gtk::TreeView which has a Gtk::ListStore as model. So I declare a Gtk::TreeModelColumn<Eurocents>, and add it to the model. I then append_column this model column to the Gtk::TreeView with an appropriate title.
I then append_row to the model and set the value corresponding to the column to (Eurocents)100.
The result I get is that the cell is displayed empty. Understandably so, because I would not expect Gtkmm to know how to render my arbitrary type.
I would like to instruct Gtkmm on how to render my type.
I already know how to display Glib types like Glib::ustring and formatting to Glib::ustring for display is possible, but it is not the subject of the question.
Is it possible to code columns that can display arbitrary types like this? And if so, how? What is required for sorting to work?
The most common, and easiest way, is to use a cell_data_func callback. For instance, you can create your own instance of a Gtk::TreeView::Column (the view column), pack a cell renderer (or more) into your Gtk::TreeView::Column, append your Gtk::TreeView::Column to the TreeView with Gtk::TreeView::append_column(), and call set_cell_data_func() on your Gtk::TreeView::Column():
https://developer.gnome.org/gtkmm/stable/classGtk_1_1TreeViewColumn.html#a3469e1adf42e5932ea123ec33e4ce4e1
You callback would then get the value(s) from the model and set the appropriate values of the properties of the renderer(s).
Here is an example that shows the use of set_cell_data_func(), as well as showing other stuff:
https://developer.gnome.org/gtkmm-tutorial/stable/sec-treeview-examples.html.en#sec-editable-cells-example
This link should also be useful:
https://developer.gnome.org/gtkmm-tutorial/stable/sec-treeview.html.en#treeview-cellrenderer-details
If you like, Gtk::TreeView::insert_column_with_data_func() makes this a little more concise: https://developer.gnome.org/gtkmm/stable/classGtk_1_1TreeView.html#a595dcc0b503a7c1004c296b82c51ac54
As for the sorting, you should be able to just call set_sort_func() to specify how the column is sorted: https://developer.gnome.org/gtkmm/stable/classGtk_1_1TreeSortable.html#a3a6454bd0a285324c71edb73e403cb1c
Then this regular sorting advice should apply: https://developer.gnome.org/gtkmm-tutorial/stable/sec-treeview-sort.html.en
I am trying to design a generalized detail page for an object.
In the controller class I find the list of all child relations of that object.
I then want to create for each child relations found and for accomplishing this I will have to dynamically set the value of list attribute within it.
For example :
<apex:relatedList subject={!ObjName} list="{!relatedListName}" />
But the problem here is that list attribute only accepts String literal, so can't implement it. Please suggest a way for this requirement to be accomplished.
Yes, you can dynamically set the value of the "list" attribute on a relatedlist tag, and you do so via Dynamic Visualforce. This question has since been asked and concisely answered here on the Salesforce Stack exchange for any future browsers:
https://salesforce.stackexchange.com/questions/7531/apexrelatedlist-list-dontexistinallorgs-c-only-solveable-with-dynamic
Here is the general solution:
In a custom controller, add a function to dynamically generate the RelatedList markup. I will assume from your wording that you have already accessed the full list of child relationships in your controller, so in order to spit out all the lists in one block, I would use something like this:
public Component.Apex.OutputPanel getDynamicList()
{
Component.Apex.OutputPanel outPanel = new Component.Apex.OutputPanel();
for(String id : childNames) {
Component.Apex.RelatedList relList = new Component.Apex.RelatedList();
relList.list = id;
outPanel.childComponents.add(relList);
}
return outPanel;
}
In the middle there, you can dynamically set any string to the "List" value, and by iterating through your list of strings, you are adding related list objects over and over again. (To simply add one list, remove the for loop, and make the "id" string value whatever specific relationship you wish to display).
Then on your visualforce page, you can render this block out using a dynamic visualforce tag:
<apex:dynamicComponent componentValue="{!DynamicList}" />
(as you may know, the formulaic value field will dig up the getter automatically)
Great success!
I would suggest trying apex:dataTable or apex:repeat to build your own list display. You will likely need a wrapper class to handle passing attributes and values from the sObject to the page.
