We are trying to use a GeneralTransform like this:
GeneralTransform gt = this.scrollViewer.TransformToVisual(Application.Current.RootVisual as UIElement);
We often, but not always, get the "Value does not fall withing expected range" exception.
Why does this happen, and is there some way to test the elements to know if the TransformToVisual() call will work?
Thanks for any insight...
You can only call TransformToVisual on an element that is visible on the screen and already layed out.

I'm using geom_bar_pattern to try to put stripes in an stacked barplot. I could run the command once, but I'm trying to do it again and it doesn't work. The error is Error in seq.default(from, to, by) : invalid '(to - from)/by'
I received the same error and realized that this was due to the limited size of my screen. I was able to see the figure and resolve the error by expanding the built-in plot viewer...
I just got the same error message with geom_bar_pattern. In my case it was entirely a matter of spacing in the plot: I had a long string of text for one axis ticks. When I reduced that, I immediately got rid of the issue!
Not sure if it's the same situation in your case, but I thought I'd answer just in case this could help...
Good luck!
I have the following two lines of code:
Debug.Print Forms!DocLoader!DL_RowBox!DLR_FileName.Name
Debug.Print Forms!DocLoader!DL_RowBox.Form!DLR_FileName.Name
The second one, which I have seen recommended in almost every VBA reference, including the answer being suggested from SO as I type this, follows this structure:
Debug.Print Forms![Form Name]![Subform Control Name].Form![Control Name].Name
These two lines of code should produce the same result. However, the second, recommended syntax throws error 40036, "Application-defined or object-defined error" unless I am in design view. I cannot use it at runtime, but I have never seen this limitation mentioned in any of the reference documentation or forum posts I have looked at. The first line, using only default parameters, seems to work no matter the context.
With the second line, I have tried just about every combination of bang and period I can, and I have also tried enclosing field names in brackets, but the common denominator is that as soon as I reference ".Form" the application throws an error. Even something simple like ".Form.Caption" has thrown an error. So what I would like to know is:
Are there any other correct ways of referring to a subform's form properties, since I need these as well as its controls
Why would the first line execute correctly while the second, recommended one does not seem to work?
Running the compiler appears to have fixed the issue.
I accidentally hit enter after a value assignment and to my surprise it compiled perfectly fine!
What's the point of having this syntax? I tried to search for it online but only found articles about the Nothing-type, but nowhere close to this surprising syntax.
Technically, return 123 is an expression which returns Nothing. Just like throw RuntimeException(). You can save the result of this expression in your variable but I cannot imagine how you can use it :)
I'm trying to return the value of a variable declared in one method and get that result in another (from where it was called). I'm a new programmer and have looked through the scoping documents on the Apple site. I'm including some (made up) code below to show what I'm trying to do. I appreciate any help I can get. Thank you in advance.
on first_method()
set bob to "This is the variable I wish to return"
return bob
end first_method
on second_method()
first_method()
end second_method
If I just call first_method() (from outside the second_method), it works fine. But I'm not able to get the value to return from within the second_method. I understand that it is a local variable. But I thought that it would be possible to return the result of the last argument and pass it back to where it was originally called. Is this incorrect? Is there any way to do what I'm attempting to pull off?
I realize this is probably really easy and I'm just demonstrating my own stupidity for not being able to find the answer. But I would really appreciate any help I could get in seeing the answer. I promise to repay the kindness someday, when I'm more experienced.
Thank you.
Something like this? You're code works perfectly. The value you return needs to be assigned to a variable maybe that's the thing you overlooked.
second_method()
on first_method()
set bob to "This is the variable I wish to return"
return bob
end first_method
on second_method()
set bob to first_method()
display dialog bob --just to show you that it works
end second_method
I have encountered something strange.
I wanted to have the value of my gridview boundfield so I did this.
SelectedID = objGridView.Rows(0).Cells(4).Text.ToString
At first this seemed to work. I played around a little created a hyperlinkfield wanted to get that value but got an empty string. After some looking around it turned out I could not get it as easily as I could with a boundtextfield. No problem.
But here comes my problem , now all of a sudden my line of code to retrieve the value from the selectedId does not work anymore ( at least I'm getting empty strings back ).
I've build and rebuild my gridview but to no avail.
I'm flabbergasted and don't get it why it doesn't work anymore.
Hence my question.
Does anyone have an idea what's happening or have a solution to this problem.
edit:
I'm seeing this in my item value
"In order to evaluate an indexed property, the property must be qualified and the arguments must be explicitly supplied by the user"
Don't know why you dont use the datagridview.
I started with GridView as well but after changing the control type it's really easy to get those values e.g:
SelectedID = dgvExample.CurrentRow.Cells("Columname/Index").Value
dgv compared with gv
There is an answer here
An other one (which was the reason of my problem) could be that the BoundFields are set to Visible = false. Invisible Bound fields are... not bound.
A simple workaround is to make it invisible in CSS instead.
Code behind :
gvColumn.ItemStyle.CssClass = "className"
CSS :
.className { display:none; }
