I want to retrieve the mail list into one field and display the data retrieved.
The mail list is represented as an array, and I want all data to be in one field.
define variable i as integer no-undo.
define variable cmmt as longchar no-undo.
cmmt = " ".
for each cd_det no-lock
where cd_ref = "test1"
and cd_type = "EL":
do i = 1 to extent(cd_cmmt):
cmmt = cmmt + cd_cmmt[i].
end.
disp cmmt.
end.
I tried the above code, but it doesn't display. Instead, test1 record contains 2 mails (gangadhar.pichika-external#gemalto.com,balkrishna.talapalliwar-
external#gemalto.com), but I didn’t get that data in cmmt.
A LONGCHAR variable cannot be displayed (unless using a large editor widget). Try to DISPLAY STRING(cmmt).

Accept a customer number and then output the details of each order and items to an editor widget.
Display them in the editor widget ( editor-1 as object name).
define temp-table ttcustomer
field custnum like customer.cust-num
field cname like customer.name
field orders like order.order-num
field items like item.item-num
field itemname like item.item-name .
find first customer WHERE customer.cust-num = input f1 NO-LOCK .
create ttcustomer .
assign
ttcustomer.custnum = customer.cust-num
ttcustomer.cname = customer.name.
for each order WHERE Order.cust-num = input f1 NO-LOCK .
assign
ttcustomer.orders = order.order-num.
for each order-line where order-line.order-num = order.order-num no-lock.
for each item where item.item-num = order-line.item-num no-lock.
assign
ttcustomer.items = item.item-num
ttcustomer.itemname = item.item-name.
end.
end.
end.
I have no idea why you would want to display that on an editor. So I'll assume you want to concatenate the info you gathered in the for each loop into an editor.
So after the last end, you could do this:
define variable editor-1 as character view-as editor.
for each ttcustomer:
assign editor-1 = editor-1 + ttcustomer.items + ' ' + ttcustomer.itemname + chr(13).
end.
display editor-1.
If chr(13) doesn't work to skip a line, try chr(10).
PS: An editor is really probably not the widget you want to display this. I'd use a browse. But since the question asks for an editor, there.
PS2: You didn't assign the other fields you put on the temp-table, so I'm not displaying them. But it's just a matter of adding them to the assign line above, not forgetting the spaces, dashes or whatever you'd like to use as a separator.
I often do the following progress 4GL code
output to /OUTText.txt.
def var dRow as char.
dRow = "cmpid|CustNum|Cur".
put unformatted dRow skip.
for each Cust no-lock:
dRow = subst("&1|&2|&3", Cust.CmpId, Cust.CustNum, Cust.Curr).
put unformatted dRow skip.
end.
output close.
in order to mimic
select * from cust (in MS SQL)
my question is is there a way to make this block of code, even closely resemblance "select *" using 4GL. Such that I don't have to type each column name and it will print all values in all columns. my thinking is. something like this.
output to /OUTText.txt.
def var dRow as char.
dRow = "cmpid|CustNum|Cur".
put unformatted dRow skip.
for each Cust no-lock:
if row = 1 then do:
for each Column in Cust:
**'PRINT THE COLUMN HEADER**
end.
end.
else do:
**'PRINT EACH CELL**
end.
end.
output close.
If there is such thing. then I don't have to keep explicit column name in dRow.
You can do what you're after if you first output all field labels (or names) and then use EXPORT to output the table content.
To change to field name instead of label: change :LABEL below to :NAME
For instance:
DEFINE VARIABLE i AS INTEGER NO-UNDO.
OUTPUT TO c:\temp\somefile.txt.
DO i = 1 TO BUFFER Customer:NUM-FIELDS.
PUT QUOTER(BUFFER Customer:BUFFER-FIELD(i):LABEL).
IF i < BUFFER Customer:NUM-FIELDS THEN
PUT UNFORMATTED ";".
ELSE IF i = BUFFER Customer:NUM-FIELDS THEN
PUT SKIP.
END.
FOR EACH Customer NO-LOCK:
EXPORT DELIMITER ";" Customer.
END.
OUTPUT CLOSE.
You could put the header part in a separate program to call dynamically every time you want to do something similar:
DEFINE STREAM str.
OUTPUT STREAM str TO c:\temp\somefile.txt.
RUN putHeaders.p(INPUT BUFFER Customer:HANDLE, INPUT ";", INPUT STREAM str:HANDLE).
FOR EACH Customer NO-LOCK:
EXPORT STREAM str DELIMITER ";" Customer.
END.
OUTPUT STREAM str CLOSE.
putHeaders.p
============
DEFINE INPUT PARAMETER phBufferHandle AS HANDLE NO-UNDO.
DEFINE INPUT PARAMETER pcDelimiter AS CHARACTER NO-UNDO.
DEFINE INPUT PARAMETER phStreamHandle AS HANDLE NO-UNDO.
DEFINE VARIABLE i AS INTEGER NO-UNDO.
DO i = 1 TO phBufferHandle:NUM-FIELDS.
PUT STREAM-HANDLE phStreamHandle UNFORMATTED QUOTER(phBufferHandle:BUFFER-FIELD(i):LABEL).
IF i < phBufferHandle:NUM-FIELDS THEN
PUT STREAM-HANDLE phStreamHandle UNFORMATTED pcDelimiter.
ELSE IF i = phBufferHandle:NUM-FIELDS THEN
PUT STREAM-HANDLE phStreamHandle SKIP.
END.
output to "somefile".
for each customer no-lock:
display customer.
end.
I wouldn't generally mention this as the embedded SQL-89 within the 4GL is the highway to hell (that dialect of SQL only works for the most basic and trivial of purposes and really shouldn't be used at all in production code), but as it happens:
output to "somefile".
select * from customer.
does just happen to work to the spec of the original question (although, like the DISPLAY solution, it also does not support a delimiter...)
I created a query and a form in Microsoft Access 2010. The form, named TEST, looks as follows:
Field1 Field2
a 200
b 400
In VBA I tried to access the different fields in the form:
Form_TEST.Field1....
I want to save the values 200 and 400 in an integer variable (Dim a As Integer) and print it using MsgBox. How can i achieve that??
You can use the Me as the open form and assign the variable if you know the name of the text box.
Dim intValue as Integer
'If text box name = TextBox1
intValue = Me.TextBox1.Value
I'll try to help you.
I understood you created the form with the wizard putting the 2 fields on the form.
What is not clear is the View that you are using.
Well, your form can be displayed in different ways:
- Single form
- Continuous forms
- Datasheet
This is defined by the Default View property.
To see the properties of you form press F4 to see properties and select "Form" as the object that you want to see.
If your form is Single Form or Continuous form you can access the two fields you put on it simply addressing them.
Click on the controls you put on the form and press F4 to see the control name.
CASE 1 - SINGLE FORM VIEW
Let's assume that your controls are named Text1 (200) and Text2 (400) and for convenience your form is a single form.
So you can refer to values in the 2 controls writing
Dim intText1 As Integer, intText2 As Integer
intText1 = Me.Text1.Value
intText2 = Me.Text2.Value
The .Value property is not mandatory cause it's the default property.
At this point you can print out intText1,2 with a MsgBox
MsgBox "Text1 = " & CStr(intText1)+ " - Text2 = " & CStr(intText2)
This will show Text1 = 200 - Text2 = 400
CASE 2 - CONTINUOUS FORMS VIEW
Let's now assume that your view is Continuous form.
So the field that contains 200 and 400 is just one but each record (row) is a form repeated as many times as the number of records.
In this case to access all the records and store them to an array you can use this in the Form_Load event (you can access it by the Control Properties Window - F4)
Option Explicit
Option Base 1 ' Set the base index for vectors to 1
Dim rst as DAO.Recordset ' Define a recordset to allocate all query records
Dim Values as Variant ' Define a variant to allocate all the values
set rst = me.RecordsetClone ' Copy all records in rst
rst.MoveLast ' Go to last record
intNumRecords = rst.RecordCount ' Count records
rst.MoveFirst ' Go back to recordset beginning
ReDim Values(intNumRecords) ' Resize Values to allocate all values
i = 1
Do While Not rst.EOF ' Cycle over all records
Values(i) = rst!FieldName ' FieldName is the name of the field of
' the query that stores 200 and 400
i = i + 1 ' Move to next array element
rst.MoveNext ' Move to next record
Loop
rst.Close ' Close recordset
set rst = Nothing ' Release memory allocated to rst
for i = 1 To intNumRecords ' Show easch value as message box
MsgBox Values(i)
next i
NOTES
Please NOte that this solution works if you have less than 32767 records to show (the maximum integer with sign that you can store).
The msgbox obliges you to press OK at each value. It's not so comfortable.
Please tell me if it's what you were looking for.
Bye,

I need help with an Excel Export. I'm trying to export a column as text using Progress 4GL. I need numbers in the column which have a leading "0" that excel keeps deleting when opens.
I tried it with using STRING function to make the variable to be String before it goes to export. It did not work. Is there any other way to export with leading 0s?
I assume that you are saving the file in progress as a CSV and when the file is opened in Excel it loses the leading 0.
When outputting the string you can enclose it as follows so that excel reads it in as a string.
put unformatted '="' string("00123") '"'
If you're writing directly to Excel, you can put a ' character at the beginning of the number, and then Excel will interpret it as number formatted with text.
You can see it in action here:
def var ch-excel as com-handle no-undo.
def var ch-wrk as com-handle no-undo.
create "Excel.Application" ch-excel no-error.
ch-excel:visible = no no-error.
ch-excel:DisplayAlerts = no no-error.
ch-wrk = ch-excel:workbooks:add.
ch-excel:cells(1,1) = "'01".
ch-wrk:SaveAs("c:\temp\test.xlsx", 51, "", "", false, false, ) no-error. /* 51 = xlOpenXMLWorkbook */
ch-excel:DisplayAlerts = yes.
ch-excel:quit().
release object ch-wrk.
release object ch-excel.
Since I've be using excel to generate reports for a while, I've create a small lib that generates an excel based on a temp-table definition, and I think it might be helpful, you can check it up at: https://github.com/rodolfoag/4gl-excel
When you import manually into excel select the columns as TEXT and not GENERAL, then the leading zero will not dissapear
You can set the format of the cell, something like this:
h-excel:Range("A12")::numberformat = FILL("0",x).
where x would be the length of the variable you want to insert.
I tried the below code :
def temp-table tt-dg1
field dtoday as date column-label "dg "
.
buffer tt-dg1:BUFFER-FIELD("dtoday"):
column-LABEL = buffer tt-dg1:BUFFER-FIELD("dtoday"):column-LABEL + "77".
display buffer tt-dg1:BUFFER-FIELD("dtoday"):column-LABEL.
create tt-dg1.
dtoday = today.
display tt-dg1 with frame f2.
Expecting field dtoday to now have a column-label of dg 77 but it's still dg, I need this to add week numbers to the standard column-labels of a spreadsheet I am creating.
Any help gratefully receieved :)
This feels like a fault.
It does not appear to work when overriding it on the temp-table.
If you define your field in a frame before display then you can overide it there.
form tt-dg1.dtoday with frame f2.
tt-dg1.dtoday:label = "MyLabel".
display tt-dg1.dtoday with frame f2.
That may or not help depending on what you are doing.
Is it possible to dynamically create the temp table? if so you can dynamically set it there
DEFINE VARIABLE ttDynTable AS HANDLE NO-UNDO.
DEFINE VARIABLE vInt AS INTEGER NO-UNDO INIT 77.
CREATE TEMP-TABLE ttDyntable.
ttDynTable:ADD-NEW-FIELD('dtoday', 'DATE', 0, "99/99/9999",?,"","dg " + STRING(vInt)).
ttDynTable:TEMP-TABLE-PREPARE("tt-dg1").
ttTTHandle = ttDyntable:DEFAULT-BUFFER-HANDLE.
ttTTHandle:BUFFER-CREATE.
ttTTHandle::dtoday = TODAY.
DISPLAY ttTTHandle:buffer-field('dtoday'):column-label ttTTHandle::dtoday.
if not you can just pull the column-label from the buffer instead
DEFINE TEMP-TABLE tt-dg1 FIELD dtoday AS DATE COLUMN-LABEL "dg ".
DEFINE VARIABLE vTTHandle AS HANDLE NO-UNDO.
CREATE tt-dg1.
dtoday = TODAY.
vTTHandle = BUFFER tt-dg1:HANDLE.
vTTHandle:BUFFER-FIELD("dtoday"):column-LABEL = vTTHandle:BUFFER-FIELD("dtoday"):column-LABEL + "77".
DISPLAY vTTHandle:BUFFER-FIELD('dtoday'):COLUMN-LABEL.
