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; }

I'm making a simple concept game, in which I've made buttons which are targets, when the user clicks said targets, it executes this code:
on (release){
_global.targetCount++;
Target1._visible=false;
if(_global.targetCount==3){
gotoAndStop(4);
}
}
the global variable was declared on the frame like this:
_global.targetCount = 0;
and the buttons do disappear when I click on them like they should, but as soon as I click the final 3rd one and it disappears, it doesn't successfully check that the if(_global.targetCount==3) and proceed to the 4th frame.
I've tried declaring the variable differently like so:
var targetCount:Number = 0;
also tried doing it like this but on using the check code button it said my syntax was wrong:
var _global.targetCount:Number = 0;
and calling every instance as just targetCount, but that didn't fix it either,
I've searched and tinkered with the code, but I can't find clear examples on global variables, the little I've used here I found by reading this:
https://www.kirupa.com/developer/actionscript/tricks/global.htm
So I was wondering if anyone here could help me by letting me know the many mistakes I've done, and how to improve them.
All help is gladly appreciated!
Every keyframe on stage is new closure. If you have variable on frame 2 and you want change/set or read value of this variable on frame 3, that variable does not exist and it is undefined. If you will try increment that undefined value you get NaN and gotoAndStop(NaN) doing nothing.
Insert trace(_global.targetCount); between _global.targetCount++; and Target1._visible=false; for debug.
Ok, I'm totally at a loss with this....
I think I have looked at every example and every code snippet around and still can't work out how to implement a custom sorter on my ObjectListView.
My primary column (column 0) contains numbers only (as a string) but is sorting all items by alphanumeric instead of numeric, meaning that it is doing something like this:
1
11
111
2
22
etc.
I am trying to find a relatively simple example of how to modify my ObjectListView to sort column 0 when it first loads, but I'm struggling.
I have converted over a custom class called ColumnSorter (from CodeProject) into VB and I'm calling the following delegate:
lvwColumnSorter = New CustomLVSorter.CustomLVSorter()
lsv_OpenTickets.CustomSorter = Sub(column As OLVColumn, order As SortOrder)
lvwColumnSorter.ColumnToSort = Ticket_Status.Index
lvwColumnSorter._SortModifier = CustomLVSorter.CustomLVSorter.SortModifiers.SortByText
lvwColumnSorter.OrderOfSort = SortOrder.Ascending
lsv_OpenTickets.ListViewItemSorter = lvwColumnSorter
End Sub
I get no errors, but I also get no change.
Any help would be greatly appreciated.
Well, are you sure you have looked at every example? I think there are a lot of resources on this one.
When you're using a list, datagridview, or any main form, you can adjust it to use a custom sorter. You create a custom IComparer, i.e. the definition of how you sort something. It can be as simple as converting the string (like yours) to an int with CInt() and returning -1 or +1 if it is greater or less than the last value. This is very common.
If you need help on the basics of how to do it, of course there are always the microsoft links that give you the basics such as Custom Sort I Comparer. But there is a stack flow that also follow your problem here: Custom sort C#
It's in C#, but there are many converters on that around here.
But the easiest way to get around it? Convert your string list into a integer list. Then it will sort perfectly.
I´m losing my mind here, I've tried every example I've found online and still can't get it to work, this is the way im creating the variable on the code that generates the report, I'm working on a .NET application:
report.Dictionary.Variables.Add(New Stimulsoft.Report.Dictionary.StiVariable("test",""))
report("test") = "ANYTHING"
While it does show me the created variables on the Stimuloft gui, it contains absolutely nothing, any ideas on what I'm doing wrong? Thanks!
You should use next code to set value of variable:
report.Dictionary.Variables("test").Value = "ANYTHING"
The code that you use will work after calling report.Compile() method only.
I'm currently working on converting a VBA AutoCAD-application over to VB.NET, and the current command I'm working on is creating a simple leader with code like this:
Set leaderObj = ThisDrawing.ModelSpace.AddLeader(points, blockRefObj, leaderType)
leaderObj.ArrowheadType = acArrowDotSmall
leaderObj.ArrowheadSize = 2.5 * varDimscale
leaderObj.DimensionLineColor = acWhite
I've been able to create the Leader-line in .NET using
Dim l = New Leader()
For Each point In jig.LeaderPoints
l.AppendVertex(point)
Next
l.Dimldrblk = arrId
The arrId I got from using the function found here, but I've been unable to figure out how to set the color of the leader to white (it shows up as red by default), and also how to set the size of the arrowhead. If anyone could help me out with this I would be most grateful.
Ok, after a lot of trial and error, I figured out that the solution was rather simple. I didn't have to override any dimension styles (which I honestly don't even know what is, I had a short beginners course in AutoCAD before getting handed this project), I simply had to set an obscure property on the Leader-object. For future references, and for anyone else trying to do the same, here's the properties I ended up using:
leader.Dimclrd
The color of the leader-line. Stands for something like "dimension line color".
leader.Dimasz
The scale of the leader-head.
As type BlockReference, it should have a color property and the property should be an Autodesk.Autocad.Colors.Color or an Integer. Also the reason you are getting the object for read is, in your transaction you are opening the database with
OpenMode.ForRead
And that is correct. But to edit the object in the database, you must retrieve the object like below
var obj = Thetransaction.GetObject(theobjectid,OpenMode.ForWrite) as BlockReferance;
This is done inside of the
using(var trans = TransactionManager.StartTransaction()){}
I'm doing this on a cell, so check the camel case and syntax because I write in c#, but it should be pretty close.
You may want to see if there is a scale property, as to change the size.
Hopefully this will move you in the right direction.
Let me know if you have any problems. :)
I am finding that whenever I load an object from my database it is immediately appearing as being Dirty.
I found some code that will let me see if the object is dirty here: http://nhforge.org/wikis/howtonh/finding-dirty-properties-in-nhibernate.aspx
var x = session.Get<MyRecord>(123);
var dirtyEntity = session.IsDirtyEntity(x);
dirtyEntity is always evaluating to true to entities of this class.
Looking into it a bit more I think I've found the root of the problem. I have a property which is mapped onto an nchar(15) column in SQL Server. The value in the DB has trailing spaces, but the value appearing on the object has been trimmed. So... the following is returning true.
var x = session.Get<MyRecord>(123);
var dirtyProperty = session.IsDirtyProperty(x, "Status");
Does anyone know how I can get nHibnernate to say that "Status OK" and "Status OK " are equivelent, and that the entity is not dirty?
Why don't you use varchar as the data type in database for the said column. This will solve your issue as well as prevent the wastage of space going on in the database.
This may be solvable by using an IUserType for the property. There is a TrimString example in UNHAddins; you can read about its usage here.
