Strange bug, items in list boxes disappearing

First of all this is my first post here ever. If its a wrong forum, sorry.
So ever since I installed Windows 8.1 here (fresh install), I have this strange bug were items in list boxes start disappearing when you open a window with them.
It didn't bother me much but now its horrible when I wanted to switch my playback device... Or if you want to change IP settings on my network adapter.
The thing is it all happens in a very short period of time so it took me a while to get screens of it and here they are:

s9.postimg.org/a0nhs0szj/bug2.gif
I still can't upload images on this forum!
That is real time of how it appears on my screen when I open those windows. You can see on the first image that the window is still appearing.
I have searched for this problem but couldn't find anything.

Help needed in removing duplicate items of list box in java

How to remove duplicate items of list box while dynamically inserting (on-click event)
It is not identifying duplicate data
Variable name is HP_G1
HP_dmg1 = (DefaultListModel) HP_G1.getModel();
int a = HP_G1.getModel().getSize();
System.out.println("HP list no--------> "+a);

Your code is unreadable, so I'll ignore it. In the future please press the message editor's CODE button to format code.
As to your problem, to the point you normally use a Set instead of List when you don't want duplicates in a collection.

How to create an alert at the list item of List box in vbs/c sharp

Dear All,
I need to know how can we create an alert, or a message on the execution of the last item in the List box.

What do you mean by "on the execution of the last item in the list box"? Do you mean when that last item of a ListBox is selected? If so, you could use the following code:
Private Sub ListBox1_SelectedIndexChanged(sender As Object, e As EventArgs) _
Handles ListBox1.SelectedIndexChanged
Dim lb As ListBox = CType(sender, ListBox)
If lb.SelectedIndex = lb.Items.Count - 1 Then
MessageBox.Show("Last item is selected")
End If
End Sub

The method of leaving cursor at selecting item of list box.

Hello.
Pleas let me ask about the subject!!!
Concerning the screen by web-dynpro, I have a problem that when I select one listbox after selecting another listbox, the screen moves up to the top automatically.
I would like to prevent from above moving.
Could anyone specialist please tell me how leaving cursor at setelcting item of the list box.
Thanks!!!

Hi...
there are two events which have been used, one is doubleclick event and the other one is on selecting the item from the list and clicking on OK button(this will be the most frequently used function, i cannot use event target event for this OK button... ) . I have attached the screen shot. Please have a look at it and let me know how can i achieve that...
I can use custom event, but the main problem is that the inline itemeditor's details are not accessible in the code.... I can access some function from within the inline itemeditor combo box using outerDocument.myFunction() (this is something like GET). Is there a similar way, to SET the data into this itemeditor?

Select item in list box using code

We use Adobe Workflow v5. I am creating a Check Request application where users type information into various fields and when they click Add, the data is added to a List Box. Also when they click Add, if the current item is >$1,000, a query searches our accounting database to see if the client has outstanding AR older than 90 days. If they do, another list box is displayed with the client name and amount of outstanding AR.
If that clientnum is already in the second list box, it does not add another one.
To delete a record from the first list box, the users select the item in the first list box, and then click a Delete button. That deletes the
record in the first list box.
I am also trying to delete the record from the second list box but am not sure how to select it using code. As part of the Delete button code, if the currently selected item (the one they want to delete) is >$1,000, I go through each row of the first list box to see if clnum.text (field in the form where the record to be deleted is now displayed) matches the client number in column 4 of any row of the first list box. If it does, I see if the amount of the item in the first list box is >$1000.
If it is, then I know that there is a corresponding record in the second list box.
Here is some of the code:
'go through each row in first list box
For irow = 1 to lstExp.ListCount
'set clientnum variable equal to client # in row in first list box
clientnum = lstExp.RetrieveItem(irow,4)
'if clientnum variable is equal to client # to be deleted from first list box (selected record - client # in clnum.text now)
if clientnum = trim(clnum.text) then
'if amt is >$1,000 in first list box
if lstExp.RetrieveItem(irow,10) > 1000 then
'don't delete row because there is another record in first list box
DeleteOutAR = "N"
else
'delete row because there is NOT another record in first list box.
DeleteOutAR = "Y"
end if
end if
Next
Here is the code I need help with. I am unsure how to select the record in the second list box so I can delete it.
if DeleteOutAR = "Y" then
'go to second list box ?
form.GoToField(lstOutARUnbilled)
'start going through second list box looking for clientnum
For irow2 = 1 to lstOutARUnbilled.ListCount
if clientnum = lstOutARUnbilled.RetrieveItem(irow2,1) then
irow2 = lstOutARUnbilled.CurrentSelection
lstOutARUnbilled.Removeitem (irow2)
end if
next
end if
So my question is, how can I move to the second list box to actually delete the record?
Thank you in advance for any help.
Mary

Mary-
The solution could either be quite easy or difficult dependent upon how the data is arranged in the subsequent list box.
Basically, if there is any sort of corresponding or matching entries, meaning line 1 from list box #1 matches with line 1 of listbox #2, then you would simply execute the following...
"listbox#2.RemoveItem listbox#1.CurrentSelection"
Or if you have a column that would contain the same values, say an index, then you could just loop thru the 2nd listbox searching for that index and once found remove the line...
"listbox#2.RemoveItem nRow"
, where nRow would be the line that you discovered to have the matching index.

How scroll through a list of items in list box with code in C# winforms to create auto scrolling

I am new to programming and I have been tasked to create a form to display information in list box controls on a big screen. The list boxes have to show all data by auto scrolling through all data row by row then start again at the top once it has displayed
all data. Is there a way to do this automatically in code using a timer? I look all over the web and have not found any way to do this in win win forms. Is it possible?
Thanks

Here's the c# code
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Text;
using System.Windows.Forms;
namespace WindowsApplication13
public partial class Form1 : Form
System.Timers.Timer timer = new System.Timers.Timer();
int position = 0;
public delegate void delegateUpdateListbox();
public Form1()
InitializeComponent();
private void Form1_Load(object sender, EventArgs e)
timer.Interval = 1000;
timer.Enabled = true;
timer.Elapsed += new System.Timers.ElapsedEventHandler(timer_Elapsed);
void timer_Elapsed(object sender, System.Timers.ElapsedEventArgs e)
position += 1;
if (position == listBox1.Items.Count)
position = 0;
delegateUpdateListbox deleg = new delegateUpdateListbox(updateListbox);
this.Invoke(deleg);
void updateListbox()
listBox1.SelectedIndex = position;
As long as the listbox's SelectionMode is set to "One" (the default), you don't have to do anything to un-select the previous item.
For your secnd question, the code inside the timer checks whether the position is the same as the length of the contents of the listbox and resets its value to zero, so that the selection will go back to the first item in the list.

How to get the display value of selected item in list box?

I have a page with an HtmlSelectOneListbox that is filled with an ArrayList of SelectItem objects.
The SelectItem objects contain a Key and Value. The Value is displayed in the ListBox.
The value parameter of the listbox is bound to a bean property which is called selectedListItem.
The bean property selectedListItem contains the Key of the SelectItem that is selected.
How do I obtain the Value of the selectedListItem?
I need to be able to get the Value field that is displayed, not just the Key to the item that is displayed.
Edited by: burferd on Nov 3, 2007 10:03 PM

How are you filling in the value of the menu? Obtain it back by the same way. Or pass it along the key in a object.

Dynamic list box

how to execute queries with the selected item in list box ? I
want to have an sql queiry that will generate when someone selects
an item in the list box. I know this is done in the where clause.
But my skills in javascript are not that good. Can this be done in
dreamweaver? If so do they have instructions on how to do it? Or
can someone give me an example on how this can be done?
thanks in advance

ok... :) You don't need skills in javascript for this. SQL
and a server side language will do just fine.
What is your working server side language? PHP, ASP,
ColdFusion, JSP...?

Is this a Bug? List Box do not scrollbar: Magic number 2461

In my case I am populating list box from database using script. I noticed strange behavior with List Box being populated more than 2461 list items. At run time List box do not display scrollbar if the list items are more than 2461. Looks like 2461 is the Magic number. I wonder if some one already noticed this behavior. I want to see the scrollbar irrespective of number of list items. In my case I need to load approximately 5000 list items. Any one has suggestions? Is it designed to behave like this or is this a Bug?
Thanks in Advance.
SekharN.

Hi,
I noticed it too !
I have several lists, some oh theme have more than 2460 items and don't have the scroll bar.
An other problem relative to scrollBar in listBox appeared : with Reader 8, i can't use the scroll bar (even if i have less than 2460 items); it appears but i can't scroll.
I see tthe french adobe team about these 2 problems next week. If we find something new, i'll tell you.

Appearance of items in a List Box

I'm working on a document in XI Pro and have a list box with 14 items. When the user chooses multiple items from that box, I'd like the unchosen items to 'disappear'. Is this possible? If so, what would I need to do? Note: users would be using Reader (not Pro).
Thank you.

Hi Vijay,

List box is not scrolling to the last item

Hello all,
I am developing a Windows Phone 8 application, in that I am using List box to display the data. I have requirement like once the page is launched user should navigate to the last item of the list box. For this requirement used scroolintoview method like LsbSample.ScrollIntoView(LsbSample.LastOrDefault).
It is moving to the last item but not fully. It is showing last item around 60% but for remaining 40% I need to manually scroll the list box.
Can any one help me to resolve this issue.
Thanks in advance.
Santosh Kumar Kotta

It's likely a small bug. Can you try scrolling to the bottom of the scrollviewer's height instead?

Select multiple items from a list box as values for a parameter of crystal report and Oracle procedure

- I have a Product list box (asp.net) used as multiple selected values for a parameter.
- The Product ID is defined in the Oracle procedure as NUMBER data type.
- In my crystal report, I have a parameter field allow multiple values as p_product_id type as Number. This is the code in my Record Selection Formula for the report:
({?p_product_id}[1] = -1 OR {Procedure_name.product_id} in {p_product_id})
- In C#, this is my code
List<decimal?> productUnit = new List<decimal?>();
int counter = 0;
decimal prod;
for (int i = 0; i < lstProducts.Items.Count; i++)
 if (lstProducts.Items[i].Selected)
 if (decimal.TryParse(lstProduct.Items[i].Value, out prod))
 productUnit.Add((decimal?)prod);
 counter++;
 if (counter == 0)
 productUnit.Add(-1);
ReportingDAO rDataFactory = new ReportingDAO();
retVal = rDataFactory.GetProductReport(productUnit);
public CrystalDecisions.CrystalReports.Engine.ReportDocument GetProductReport(List<decimal?> productUnit)
 CrystalDecisions.CrystalReports.Engine.ReportDocument retVal = new rptProductDownload();
 ReportLogon rptLog = new ReportLogon();
 rptLog.Logon(retVal, "RPT_PRODUCT_DOWNLOAD");
 retVal.SetParameterValue("p_product_id", productUnit);
I keep having the "Value does not fall within the expected range" when I debug. My question is, is the data type I used for procedure/Crystal report/ and C# correct ? I always have problem with the data type. Any help would be
appreciated
Thank you

How to edit the list box items in labwindow/CVI?

how to edit the list box items in labwindow/CVI?

Listbox items cannot be edited directly in the control: what you can do is to select a line an, transfer its content to a textbox control, edit text there and move text back to the listbox control. Available interactions with the listbox control are listed in the help.
An alternative to it is to use a tree customized to appear like a listbox: tree item labels can be edited directly in the control, at least those in the base column of the tree. You can look at the example \samples\userint\treelist.cws that shows how a tree can be customized this way. I haven't opened it, but this old example too should show the ability to edit tree cells.
Proud to use LW/CVI from 3.1 on.

Limit of no. of items shown in ABAP List-box?

Hi All,
I am doing a development and I came across this limitations of the no. of items in a list box. Is it limited to a single digit..? Cause when i use call function 'VRM_SET_VALUES', the value returned in the field is the KEY, which is only 1 digit in my case. I have over 100 entries to be displayed in the list box. Can anyone tell me how to increase the no. of digits which get returned by the FM 'VRM_SET_VALUES'?
Please let me know.
Awaiting your reply.
Regards,
Pankaj.

Show us the code that you use to build the VRM table please.
I'm simply not understanding your problem. VRM table has 2 fields, key and text. Text is what is displayed and key is what is
returned from the user selecting one item on the list. Only one value is returned. There is not multiple selection options.
This is code I use to generate a custome dropdown list.
* this is in my TOP (Global area)
DATA: ltype_field   TYPE vrm_id,
      ltype_result TYPE STANDARD TABLE OF vrm_value,
      ltype_val     LIKE LINE OF ltype_result.
* this is in my PBO routine
REFRESH ltype_result. CLEAR ltype_result.
* Drop down values
SELECT ltype ltypex
    INTO TABLE ltype_result
    FROM zlmltyp
    WHERE auth NE '9'.    "System Only
* Field name to assign drop down values
ltype_field = 'WK_LTYPE'.
CALL FUNCTION 'VRM_SET_VALUES'

            id              = ltype_field
