How to add column to FoxPro file using DAO - vb6

I need to add some columns to a FoxPro 2.6 DBF file using DAO in VB6.
If the data were in an .MDB file, I know this would work. Here is a code snippet which I use for .MDB:
Set tdfCoParms = mDBParms.TableDefs(CoParms)
tdfCoParms.Fields.Append tdfCoParms.CreateField("CoName", dbText, 30)
Am unsure if this works for FoxPro. (I have not tried)
Is this possible? There is a possible alternative - which I know would work, but which is not so convenient - by starting with an empty table of the correct structure, then copying across the records from the existing populated file, using INSERT of a SELECT from this.

Thank you #wqw, as your solution certainly works.
This was my first alternative, which worked:
Create an empty file/table with the desired columns.
Copy this file to "test.dbf".
Insert records from the populated data file "link" into this.
Dim dbsWork As Database
Dim qrd As DAO.QueryDef
Dim szSqlString As String
Set dbsWork = OpenDatabase(szWorkDir, False, False, "FoxPro 2.5")
Dim szFieldList As String
szFieldList = "field1, field2, field3"
szSqlString = "INSERT INTO test SELECT " & szFieldList & " FROM link"
Set qrd = dbsWork.CreateQueryDef("", szSqlString)
qrd.Execute
Set qrd = Nothing
Set dbsWork = Nothing
But the following based on #wqw's suggestion is much better, as no predefined file is required
Private Sub Test1()
Dim dbsWork As Database
Dim qrd As DAO.QueryDef
Dim szSqlString As String
Set dbsWork = OpenDatabase(MyDataBasPath, False, False, "FoxPro 2.5")
Dim szFieldList As String
szSqlString = "ALTER TABLE work.dbf ADD COLUMN fred VARCHAR(30)"
Set qrd = dbsWork.CreateQueryDef("", szSqlString)
qrd.Execute
Set qrd = Nothing
Set dbsWork = Nothing
End Sub

MS Access underline text in a Table

I have long Text field in a table in MS ACCESS. I need to underline it for specific text in a field. I tried to change Text format to Rich Text in the design view , but I am getting:
Error : Operation is not supported for this type of Object
In the table I have 320 rows. I need to Underline for N.J.S.A. only in the long text.
Please help me regarding this. Thanks in Advance
Well... you have to get that field property changed from plain text to rich text for this to work and design view should handle this. If not try the below code.
Public Sub TestUnderline()
Dim db As DAO.Database
Dim tbl As DAO.TableDef
Dim fld As Field
Dim rst As DAO.Recordset
Dim strSQL As String
Dim strString As String
Set db = CurrentDb
Set tbl = db.TableDefs("Table1") 'Change to your table name
Set fld = tbl.Fields("TestField") 'Change to your field name
With fld.Properties("TextFormat")
If .Value = acTextFormatPlain Then
.Value = acTextFormatHTMLRichText
End If
End With
strSQL = "SELECT TestField " & _ 'Change to your Field name
"FROM Table1;" 'Change to your table name
Set rst = db.OpenRecordset(strSQL)
Do While Not rst.EOF
If InStr(1, rst![TestField], "N.J.S.A") Then 'Change to your field name
strString = Replace(rst![TestField], "N.J.S.A", "<u>N.J.S.A</u>") 'Change to your field name
rst.Edit
rst![TestField] = strString 'Change to your field name
rst.Update
End If
rst.MoveNext
Loop
EndCode:
If Not rst Is Nothing Then
rst.Close
Set rst = Nothing
End If
If Not tbl Is Nothing Then
Set tbl = Nothing
End If
If Not db Is Nothing Then
Set db = Nothing
End If
End Sub

Classic ASP Iterate through and Object

I'm a PHP developer, learning ASP.
I've become very reliant on PHP's useful functions: print_r() and var_dump() to see what an array or object contains.
I don't always know what columns are in a Db Table. So, when a SELECT * From Tbl is queried, and the objRS is populated, would I be able to view what the entire object's contents are?
Is this possible in ASP?
<% `my simple Select statement
Dim strDbConnection
Dim objConn
Dim objRS
Dim strSQL
strDbConnection = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=d:\test.mdb;"
Set objConn = Server.CreateObject("ADODB.Connection")
objConn.Open(strDbConnection)
strSQL = "SELECT * FROM persons"
Set objRS = objConn.Execute(strSQL)
If objRS.EOF Then
Response.Write("No items found")
Else
Do While Not objRS.EOF
' show all columns I can extract here....
objRS.MoveNext()
Loop
End If
objRS.Close()
Set objRS = Nothing
objConn.Close()
Set objConn = Nothing
%>
-- I would like to see what's coming back at me in the objRS, and then cherry-pick the columns after I know what I have access to.
Is there something similar to what I'm used to?
ie: print_r()
You can use objRS.fileds(j).name and objRS.fields(j).value to get the name of columns and values.
For example:
[...]
for j = 0 to objRS.fields.count - 1
response.write(objRS.fields(j).name & " = " & objRS.fields(j).value)
next

How can I create datareport using recordset in vb6?

Private Sub showreport_Click()
sql = "select * from student_record_database where"
sql=sql+ Grade='" & Combo1.Text & "' AND Meal='" & Combo11.Text & "'"
Set RES = CON.Execute(sql)
Set DataReport1.DataSource = RES
DataReport1.WindowState = vbMaximized
DataReport1.Show vbModal
End Sub
I am using this code as record set to create a data report.
My task is to choose options from various combo boxes and then display it's report so record set is needed there..
My question is that whether this code is sufficient to create data report???
I didn't set any properties of data environment or data report such as (connection - command - sql) because I am passing this record set directly to data report,then no need to fire any sql in properties of data environment.
But unfortunately it is not showing desired output
Please help me.
Try this one:
Private sub cmdprint_click()
Dim rs as new adodb.recordset
rs.open "SQL Query Statement Here",CON, adOpenDynamic, adLockOptimistic
set datareport1.datasource=rs
datareport1.show
end sub
Notes:
The data report datasouce should be cleared during design mode. (See properties on the datareport and set its datasource property to empty.) Ohhh...one more thing, please keep in mind that you should set also the datafield property for each textbox object inside the datareport corresponding to the datafield on your database during design time...
I am using this method for a long time and it works fine.
Try this.
To add a quite to a string, use a double quite.
Also you missed spelled the second Combo1 reference as Combo11
Private Sub showreport_Click()
sql = "select * from student_record_database where "
sql = sql & "Grade=""" & Combo1.Text & """ AND Meal=""" & Combo1.Text & """"
Set RES = CON.Execute(sql)
Set DataReport1.DataSource = RES
DataReport1.WindowState = vbMaximized
DataReport1.Show vbModal
End Sub

How to copy rows of from one sheet to another sheet using vbscript

Suppose I have Sheet(1) in an excel. Now i do also have 2500 rows which has data for the columns from A to BO.Now I want the data to copy from these sheet to another sheet of the same Excel file for 2500 rows but not the whole the columns,rather i need only columns from A to AA data to copy to the new sheet.
So how to frame it using VBscript?
Please help me.
How to copy rows of from one sheet to another sheet using vbscript
To copy data from one sheet to another you can use the Copy en PasteSpecial commands. To do this with a .vbs script do the following:
' Create Excel object
Set objExcel = CreateObject("Excel.Application")
' Open the workbook
Set objWorkbook = objExcel.Workbooks.Open _
("C:\myworkbook.xlsx")
' Set to True or False, whatever you like
objExcel.Visible = True
' Select the range on Sheet1 you want to copy
objWorkbook.Worksheets("Sheet1").Range("A1:AA25").Copy
' Paste it on Sheet2, starting at A1
objWorkbook.Worksheets("Sheet2").Range("A1").PasteSpecial
' Activate Sheet2 so you can see it actually pasted the data
objWorkbook.Worksheets("Sheet2").Activate
If you want to do this in Excel with a VBS macro you can also call the copy and paste methods. Only your workbook object will be something like ActiveWorkbook
This code is Working fine. Just Copy and paste it.
Dim CopyFrom As Object
Dim CopyTo As Object
Dim CopyThis As Object
Dim xl As Object
xl = CreateObject("Excel.Application")
xl.Visible = False
CopyFrom = xl.Workbooks.Open("E:\EXCEL\From.xls")
CopyTo = xl.Workbooks.Open("E:\EXCEL\To.xls")
For i = 0 To 1
''To use a password: Workbooks.Open Filename:="Filename", Password:="Password"
If i = 0 Then
CopyThis = CopyFrom.Sheets(1)
CopyThis.Copy(After:=CopyTo.Sheets(CopyTo.Sheets.Count))
CopyTo.Sheets(3).Name = "Sheet3"
Else
CopyThis = CopyFrom.Sheets(2)
CopyThis.Copy(After:=CopyTo.Sheets(CopyTo.Sheets.Count))
CopyTo.Sheets(4).Name = "Sheet4"
End If
Next
CopyTo.Sheets(1).Activate()
CopyTo.Save()
'CopyTo.SaveAs("E:\EXCEL\Check.xls")
xl.Quit()
Sub buildMissingSheet(strMissingSheet) 'Just passing the missing sheet name in
' Master Sheet code
' Working on creating the "Master Sheet" at this time...May need to seperate the the code a little.
Dim GetRows1 As Worksheet
Dim GetRows2 As Worksheet
Dim PutRows As Worksheet
Dim sglRowNum As Single, i%
If strMissingSheet = strMASTERSHEET Then ' Create the strMASTERSHEET
Set GetRows1 = Sheets(strRAWDATA) ' These two sheets could be missing but will code around that later.
Set GetRows2 = Sheets(strDATAWITH) ' The two sheets I am getting rows from
' Just creating a new worksheet here assuming it is missing
Worksheets.Add(After:=Worksheets(5)).Name = strMissingSheet
Set PutRows = Sheets(strMissingSheet) ' Missing sheet must be created before declaring.
PutRows.Select 'Select the sheet being built.
With Cells(1, 1)
.Value = strRAWDATA 'Not copying rows here but left it in this example anyway
.AddComment
.Comment.Visible = False
.Select
.Comment.Text Text:= _
Chr(10) & "Name of sheet including header and the last 32 entries at the time this sheet was updated."
End With
'Here is where we copy the whole row from one sheet to the other.
GetRows1.Rows(1).Copy PutRows.Rows(2) 'Copy header row from existing sheet to "Master Sheet" for instance.
GetRows1.Select
sglRowNum = ReturnLastRow(ActiveSheet.Cells) 'return last row with data on active sheet
' I wanted the last few rows of data "32 rows" so found the end of the sheet this code can be found on the internet in several places including this site.
'Now the code you may have been looking for move 32 row of data from one sheet to another.
For i = 1 To 32 'Start at row 3 on the Put sheet after sheet name and header.
GetRows1.Rows(sglRowNum - (32 - i)).Copy PutRows.Rows(i + 2)
Next i
end sub

How to add data to a specific column in an existing excel file using VBScript

I'm currently doing automation testing and need to write a dynamic value to an existing excel document in a specific column, this is what I have so far. Forgive I'm a novice
Sub WriteTRNtoExcelDoc
Dim fileName, sheetName
fname = "<Path_To_The_File>"
sheetName = "Sheet1"
Set app = Sys.OleObject("Excel.Application")
Set book = app.Workbooks.Open(fname)
Set sheet = book.Sheets(sheetName)
' What do I do next to add a value to a specific column or cell in this
' spreadsheet?
End Sub
Thanks in advance!
You create an Excel instance in a VBScript with
CreateObject("Excel.Application")
An already running Excel instance can be grabbed with
GetObject(, "Excel.Application")
In a worksheet you can access cells by using the Cells property:
Set app = CreateObject("Excel.Application")
app.Visible = True
Set book = app.Workbooks.Open(fname)
Set sheet = book.Sheets(sheetName)
sheet.Cells(2,3).Value = "foo"
Edit: If you need to find the first empty cell in a given column, you can use something like this:
row = 1
Do Until IsEmpty(sheets.Cells(row, 3).Value)
row = row + 1
Loop
sheet.Cells(row, 3).Value = RemPropValue
