Matrix addrow problem

I want to enter some value in a matrix
I enbled matrix with
oMatrix.AddRow()
but problem is
that - when I am inputing data in matrix fields , after pressing tab the value disappears
how can I resolve the problem?

thts because your matrix's columns are not bound with any user or DB datatsource. alternatively , you will have to bind it with the columns of table to which you are saving the data.

Matrix.AddRow "eats" rows

Hello
I'm trying to do sorting on matrix object. I'm almost there but there is small problem. Here is the code
                for (int i = 0; i < dbDataSource.Size; i++)
                    dbDataSource.Offset = sortedList<i>.Idx;
                    matrix.AddRow(1, ++i);
every time I fire double click event (which contains sorting code) my matrix will show less and less items until it becomes blank.
If it helps somehow I'm posting code which I use for actual sorting.
            if (pVal.ColUID == "col_dost")
                matrix.Clear();
                List<Dostawca> dostawcy = new List<Dostawca>();
                DBDataSource dbDataSource = form.DataSources.DBDataSources.Item("@CT_PRP1");
                int count = dostawcy.Count;
                int k = 0;
                for (int i = 0; i < dbDataSource.Size; i++)
                    string sValue = dbDataSource.GetValue("U_CardName", i);
                    Dostawca dostawca = new Dostawca();
                    dostawca.Nazwa = sValue;
                    dostawca.Idx = k;
                    dostawcy.Add(dostawca);
                    k++;
                var sortedList = dostawcy.OrderBy(x => x.Nazwa).ToList();
                for (int i = 0; i < dbDataSource.Size; i++)
                    dbDataSource.Offset = sortedList<i>.Idx;
                    matrix.AddRow(1, ++i);
and here is my "Dostawca" class
    public class Dostawca
        private string _nazwa;
        private int _id;
        public Dostawca() { }
        public string Nazwa
            get
                return _nazwa;
            set
                _nazwa = value;
        public int Idx
            get
                return _id;
            set
                _id = value;

Ok, never mind. I see the problem.

Matrix addrow

Hi
I have a simple form. As soon as i click Addrow button i need to add a row in the matrix. I have opened the form first time and clicked addrow buttond a new row is getting added into the matrix. Now i have clicked the cancel button in the form. And then i reopened the form again when i click addrow button 2 new rows are getting added. but i need to add only single row.
Please let me know the solution. i have given the sample code for your reference.
Private Sub SBO_Application_ItemEvent(ByVal FormUID As String, ByRef pVal As SAPbouiCOM.ItemEvent, ByRef BubbleEvent As Boolean) Handles SBO_Application.ItemEvent
If (FormUID = "Frm_QTENT1") Then
                If (pVal.Before_Action = False) Then
                    If (pVal.ItemUID = "Addrow") And (pVal.EventType = SAPbouiCOM.BoEventTypes.et_CLICK) Then
                        Dim f As SAPbouiCOM.Form
                        Dim oMatrix As SAPbouiCOM.Matrix
                        f = SBO_Application.Forms.Item(FormUID)
                        oMatrix = f.Items.Item("mat1").Specific
                        f.DataSources.DBDataSources.Item(1).Clear()
                        oMatrix.AddRow(1)
                    End If
                End If
            End If
End sub
You can also test . Just add a matrix to a form and then add one button. In the itemevent just past the code above and run the form. And then click addrow button
you can see a new row is added into the matrix. When cancel the form. And now open the form again now click add button only once. You can see 2 rows are getting added. The code what is pasted will be fired 2 wise .
Please let me know how can i solve this problem.
If any one able to solve this problem i will give full reward points

Can you help me to solve this matrix filling problem?

Hi,
I need to fill a matrix column. this is the description briefly.
1.This is my binding
oForm.DataSources.UserDataSources.Add("usr_col5", SAPbouiCOM.BoDataType.dt_DATE, 50);
oColumn = oColumns.Add("Col5", SAPbouiCOM.BoFormItemTypes.it_EDIT);
                oColumn.Description = "Konteringsdato";
                oColumn.TitleObject.Caption = "Konteringsdato";
                oColumn.DataBind.SetBound(true, "", "usr_col5");
                oColumn.Width = 89;
                oColumn.Editable = false;
2.I am going to fill this column using record set's field. all of the other column's fillings are ok.but problem is here
oForm.DataSources.UserDataSources.Item("usr_col5").Value = oRs.Fields.Item("DocDate").Value.ToString();
I think there should be a casting instead of of using ToString(). But i couldn't able to do it. So please help me.

Hi,
you can try once to set
((SAPbouiCOM.EditText)((SAPbouiCOM.Matrix)(oForm.Items.Item("mtxItemUID").Specific)).Columns.Item("Col5").Cells.Item(cellnumber).Specific).String = oRs.Fields.Item("DocDate").Value.ToString();
or
((SAPbouiCOM.EditText)((SAPbouiCOM.Matrix)(oForm.Items.Item("mtxItemUID").Specific)).Columns.Item("Col5").Cells.Item(cellnumber).Specific).Value = oRs.Fields.Item("DocDate").Value.ToString();

ds.MoveFirst()
oColumn = oColumns.Item("col_0")
For i = 0 To ds.RecordCount - 1
oColumn.ValidValues.Add(ds.Fields.Item("Code").Value, ds.Fields.Item("Desc1").Value)

Crystal Repoorts 2008 W2008R2 Dot Matrix Printing Problems

Using CR2008 running on Windows Server 2008R2 - printing toLexMark 2580n dot matrix printers.
I have developed reports that print correctly WHEN I call them up in Crystal Reports 2008 and print them from that application. If I call that same report from within a Visual Studio application, it does not print at all as expected (or desired!!). Similarly, I cannot get other reports to print correctly running directly out of Crystal yet if I call them from the Visual Studio application it does work/behave.
Also, I have some label reports that are printing to a 3.5"W x 2.0"H size (I created a custom label like usual in printer server properties) that behave when I run them directly from Crystal but consistently print out vertically (90 degrees to the right) when I run it from Visual Studio. It's maddeming. I tested the reports when I first purchased CR2008 to make sure it would run on W2008R2 Server (and it did work). Did not see this problem coming. Any assistance would be helpful.
FYI I am printing to LexMark 2580n dot matrix, brand new printers (had to purchase these to make drivers work on W2008R2). LexMark has effectively (to my satisfaction) ruled out their printers as the problem.
Any advice would be greatly appreciated.

but i am not executing that VO so why should show the previous rows.
i am required only when i click a button then a new row will be generated.
please suggest.
Regards
Mofizur

Hi Mofizur
You can create a submit button for Add rows and write below code for creating a new row
//in AM
public void addRow()
    OAViewObject vo = getYourVO1();
    if (!vo.isPreparedForExecution())
    vo.setWhereClause("1=0");
      vo.executeQuery();
Row row = vo.createRow();
   vo.insertRow(row);
   row.setNewRowState(Row.STATUS_INITIALIZED);
}Call above method from controller on ADD Rows button event.
Thanks

Matrix CFL problem

Hello
I have a following problem:
I want to make one column in matrix editable and CFL(from OITM).
If I bind it with userdatasource, the chosen value cannot be changed later.
If I bind it with DBdatasource, when I choose the proper value in CFL, I get an error :Bad form Value.
I made very similar thing but not with columns(with form items) and then I could bind an item with EditText field and everything was cool. edittext1 = (SAPbouiCOM.EditText)oItem.Specific;
But now I cannot convert a column to EditText object
Anybody help me, please?

Could you send me more code to look for the problem?

I cant say when this started but at some point holding option while dragging a note to copy it stopped working as expected. Basically I want to copy a note in the matrix editor and I want it to go where I drag it (am I asking too much?). Right now as soon as I drop the note in the desired position it jumps forward several beats. Did I do something that changed the way the option key works? If I just drag the note without holding option the note goes where I want it. But as soon as I option + drag. I get this wackyness!! its hugely frustrating! Thanks in advance for any help.

Well I have a workaround now but am still confused. I discovered that if I click the little button "featuring a square graphic" in the upper left corner of my matrix window (manual says its called the "Up One Display Level button—or
UDL button"), it fixes the problem... for that matrix edit window only. As soon as I close it and reopen it (by double clicking on a midi region) it goes back into crazy freak **** mode. Something else I noticed is that when I reopen the matrix editor window the little screen read out area (that displays the notes etc under Edit/Functions/View) says "sel 1" right above the notes etc. It says this when its in crazy freak **** mode. When I click the UDL button it changes from "sel 1" to "1/AudioInst 1" which is the instrument for the midi Im working on. So how do I get crazy freak **** mode to stop messing up my matrix editor windows? Its great to have a workaround but its a pain in the butt to have to remember to push this button ( that I never needed to push before) so I can properly option+drag a midi note. I tried reading the manual about this button but I just dont get what its for (other than turning off freak **** mode). And I forgot to mention my logic version before: Logic version 7.2.1 (959.30) Thanks again in advance if you can help me:)

Printing using dot matrix printer,problem with landscape printing

Hi all,
We are planning to use Dot matrix printers for printing through SAP.We do front end printing using Windows OS. I am able to get prints properly if it is a script form. In case of list outputs, printer is printing the text outside the paper.Only half of the text is printing on the continuous stationary. Actually document is to be printed in Landscape format. So printer should print data vertically on the paper,but it's printing horizontally. I have created sparate output device for this printer.My printer is TVS Electronics HD745 24 Pin heavy duty printer. I have assigned OKI341 as device type for this device.Any more settings I need to do to get printing in landscape mode?

2D Matrix, Compacting problem

Hi!
I'm about to implement a matrix class that need som kind of "compacting" support, meaning:
If the the following matrix (3x4) is compacted:
[1][0][2][8]
[7][0][3][9]
[0][0][0][0]
The resulting matrix (2x3)would be:
[1][2][8]
[7][3][9]
Column 2 will be removed since it's empty (only zeros)
and row 3 will be removed as well sinces its empty.
I've tried a number of solutions, but they are all inneficient and/or cumbersome.
I'm thinking like this:
Find out which rows and columns should be removed.
Create a new matrix with the new size, and iterate over the first matrix copying the values.
Any ideas that come to mind?
What about choice of datastructure?
Is the best I can do to use a long[][] or maybe a
combination of Lists of some sort?
Any ideas for the algorithm?
Oh, the size of the matrix will in most of the times be around 80x80 to maybe 120x120 (not necessarily same rowcount as colcount)
And it must support getting/adding at specific cells, because of the way it's filled with values (from database)
/ Ronnie

Find out which rows and columns should be removed.Well, that's easy. Two arrays of booleans, initially all false, iterate through the entire matrix setting appropriate booleans to true if you find a non-zero element.
Create a new matrix with the new size, and iterate over the first matrix copying the values.Convert each array of booleans into an array of ints, which are the subscripts of the boolean arrays which were true. E.g. {f, t, ,t f, t} -> {1, 2, 4}.
The sizes of these arrays give the matrix size. Two nested loops to copy elements across.

Addrow problem in "Define Serial Numbers" form

I have an item which is maintained by series nos at all transactions. i have to create series nos for that item for all documents. I have developed a specific logic for series nos for populating the nos in the "Define Serial Numbers" form matrix. When i am adding a row to the matrix it shows me a row id of 0 due to which even when i update the series nos only the first row is saved . Please provide a solution. i am using 2004.2b pl:40 SAP B1.

HI,
To update serial nos to delivery use the following FM L_SER_WS_DELIVERY_UPDATE.
Use as follows
    CALL FUNCTION 'SERIAL_INTTAB_REFRESH'
      EXPORTING
        objects_status_refresh = 'E'.
    CALL FUNCTION 'L_SER_WS_DELIVERY_UPDATE'
      EXPORTING
        vbkok_wa                 = y_wa_vbkok
        synchron                 = 'X'
        commit                   = ' '
        delivery                 = y_p_vbel
        nicht_sperren            = 'X'
        if_get_delivery_buffered = ' '
        if_error_messages_send_0 = 'X'
        it_sernr_update          = y_li_sernr
      EXCEPTIONS
        error_message            = 1
        OTHERS                   = 2.
    CASE sy-subrc.
      WHEN 0.
        COMMIT WORK.
      WHEN OTHERS.
        MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
                WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
    ENDCASE.
