Good eve guys.
I'm having a problem with my code.
The goal is, when I type a letter in the combobox, it wiill show a list of possible model names.
But whenever I type in that combobox, it gives me an error.
Here's the code I'm working on:
Private Sub cmbSearch_Change()
Dim conn As New ADODB.Connection
Dim record As New ADODB.Recordset
Dim model As String
model = cmbSearch.Text
If cmbSearch.Text <> "" Then
conn.Open "Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & App.Path & "\Database.mdb"
cmbSearch.Clear
record.Open "SELECT Model FROM LaptopSpecs WHERE Model LIKE '" & model & "%' ORDER BY Model", conn, 3, 3
If record.RecordCount > 0 Then
Do While Not record.EOF
cmbSearch.AddItem record.Fields("Model").Value
record.MoveNext
Loop
End If
cmbSearch.Text = model
End If
Set record = Nothing
Set conn = Nothing
End Sub
In the part conn.open, the error message pops up.
run-time error '-2147467259(80004005)': unspecified error
Assuming you are using Access:
This question isn't about Access, but if it where:
Expanding on this answer, I recommend removing all the code in your example, and replacing it with this (done in Form design mode):
Set the cmbSearch.RowSource property to a fixed query like:
SELECT Model FROM LaptopSpecs ORDER BY Model
Set the cmbSearch Auto Expand to True.
This will work for 98% of all ComboBox type-to-select scenarios, and should work for your example.

I have a main report (Projects Overview) which I am trying to create an OnClick event which will take me from the report to the field where that piece of information is entered on a form (LiveJobs).
My problem is that there is a subform (Estimate Items Subform) where the order items are entered. Then there is a subform on that (Production Subform) which is where the components that make up the 'Item' are entered. So a 'Desk' is ordered under 'Items' and then the components of the desk - drawer boxes, top, privacy panel are all entered on the Production Subform so they can all be tracked and monitored for production. As they are being produced there is time scheduled for each of these items in a time slot corresponding to a particular week.
In the report I want to be able to click on the time scheduled for any component and link back to the form and the corresponding week where it is scheduled and move hours around within the order form. My code will currently take me to the correct job but it wont get me to the correct 'layer' of the first subform and then to the correct layer of the component. Lets say for example the 3rd item in an order and then the 2 component of that Item.
Below is my code as it sits currently which only goes as far as trying to get to the correct item on the first subform. I figured if I could figure that out I could use the same logic to get to the correct component. This code results in a "Runtime Error '13' Type Mismatch"...I have been going round and round with this for days... Thanks in advance for any and all help.
Private Sub Estimated_hours_for_current_week_Click()
Dim strWhere As String
Dim DocName As String
DocName = "LiveJobs"
strWhere = "[Job Number]=" & "'" & Me![Job Number] & "'"
DoCmd.OpenForm DocName, acNormal, , strWhere
Forms![LiveJobs].[Estimate Items Subform].SetFocus
'find the Item in the item subform
Dim dbs As DAO.Database
Dim RstItem As DAO.Recordset
Dim strItemCriteria As Integer
Set dbs = CurrentDb
Set RstItem = dbs.OpenRecordset("Estimate Items Subform table", dbOpenDynaset)
strItemCriteria = "[Estimate Item subform table ID] = '" & Me.Estimate_Item_subform_table_ID & "'"
With RstItem
RstItem.MoveLast
DoEvents
RstItem.FindFirst strItemCriteria
Debug.Print (strItemCriteria)
If .NoMatch Then
MsgBox "No Match Found"
End If
End With
Set rs = Nothing
End Sub
I figured out the code. Here it is for reference.
Private Sub Estimated_hours_for_current_week_Click()
Dim frm1 As Form
Dim frm2 As Form
Dim rst1 As DAO.Recordset
Dim rst2 As DAO.Recordset
DoCmd.OpenForm "LiveJobs", _
WhereCondition:="[Job Number]=" & "'" & Me![Job Number] & "'"
Set frm1 = Forms!LiveJobs.Estimate_Items_Subform.Form
Set frm2 = Forms!LiveJobs.Estimate_Items_Subform!ProductionComponentSubform.Form
Set rst1 = frm1.Recordset.Clone
Set rst2 = frm2.Recordset.Clone
With rst1
.FindFirst "[Estimate Item subform table ID] =" & Me.Estimate_Item_subform_table_ID
If .NoMatch Then
MsgBox "Item not found"
Else
frm1.Bookmark = rst1.Bookmark
End If
End With
With rst2
.FindFirst "[Estimate details ID]=" & Me.Estimate_details_ID
If .NoMatch Then
MsgBox "project not found"
Else
frm2.Bookmark = rst2.Bookmark
Forms![LiveJobs].SetFocus
Forms![LiveJobs]![Estimate Items Subform].SetFocus
Forms![LiveJobs]![Estimate Items Subform]![ProductionComponentSubform].Form![Estimated
hours for current week].SetFocus
End If
End With

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)

lets call it modUser.
In this modUser I have a ADODB record set
Now from this modUser, I would like to open a form. Lets call it frmUser2.
when this frmUser2 initialize. I would like to use the recordset that I already have from modUser. How do I pass this recordset from modUser to frmUser2?
I tried creating a public sub under frmUser2. But I get an error that says "Run time error 13 type mismatch"
here is a snippet
sSQL = "select name from employee"
rs.Open sSQL, ADOCon, adOpenKeyset
If rs.RecordCount > 1 Then
frmUser2.PopulateList(rs)
End if
in frmUser2 I have the public function ( i tried sub too)
Public Function PopulateList(rs As ADODB.Recordset)
For Count = 0 To rs.RecordCount - 1
LstModels.AddItem rs(0)
rs.MoveNext
Next
rs.close
End Function
I tried show , and I can get the form to appear, but I have no way to pass the record set.
frmUser2.Show
Please help. Thank you
I'm not a fan of how you're trying to do this, but working with what you want to do, first create a public Recordset property in your form and assign the recordset to it from your module before showing the form.
Module code:
Dim objForm As frmUser2
sSQL = "select name from employee"
rs.Open sSQL, ADOCon, adOpenKeyset
If rs.RecordCount.EOF = False Then
Set objForm = New frmUser2
frmUser2.Recordset = rs
frmUser2.Show
End if
Form Code:
Private Sub Form_Load()
If Not Recordset Is Nothing Then
PopulateList
End If
End Sub
Public Function PopulateList()
Recordset.MoveFirst 'defensive, make sure we're on the first record
LstModels.Clear
Do While Recordset.EOF = False
LstModels.AddItem Recordset(0)
Recordset.MoveNext
Next
Recordset.Close
End Function
I think it would be preferable for the module to have a public method that returns an employee recordset. Your form would call that method when it needs the data. Set rsEmployees = modUser.GetEmployees()
I'm having a hard time trying to gather data from an Oracle DB. I've managed to get the connection going, so the problem lies within the query. At the moment the query dont return anything, and neither VBA complains about it.
Here's the code:
Sub Connect_XXXX()
Dim conn As ADODB.Connection
Set conn = New ADODB.Connection
Dim rs As New ADODB.Recordset
Set rs = New ADODB.Recordset
Dim myQuery As ADODB.Command
Set myQuery = New ADODB.Command
conn.Open "Provider=OraOLEDB.Oracle;" & _
"Data Source=XXXX;" & _
"User Id=YYYY;" & _
"Password=ZZZZ"
myQuery.ActiveConnection = conn
myQuery.CommandText = "SELECT sta.index_id, sta.index_action as Action, sta.ticker, sta.company, sta.announcement_date as A_Date, sta.announcement_time as A_Time, " & _
"sta.effective_date as E_Date, dyn.index_supply_demand as BS_Shares, dyn.net_index_supply_demand as Net_BS_Shares, dyn.est_funding_trade as BS_Value, " & _
"dyn.trade_adv_perc/100 as Days_to_Trade, dyn.pre_index_weight/100 as Wgt_Old, dyn.post_index_weight/100 as Wgt_New, dyn.net_index_weight/100 as Wgt_Chg, " & _
"dyn.pre_est_index_holdings as Index_Hldgs_Old, dyn.post_est_index_holdings as Index_Hldgs_New, dyn.net_est_index_holdings as Index_Hldgs_Chg, sta.index_action_details as Details " & _
"FROM index_analysis.eq_index_actions_dyn dyn, index_analysis.eq_index_actions_static sta " & _
"WHERE (sta.action_id = dyn.action_id) AND (sta.announcement_date=dyn.price_date) AND (sta.announcement_date >= '01-January-2015') AND (sta.announcement_date <= '30-January-2015') " & _
"ORDER by sta.index_id,sta.announcement_date"
Set rs = myQuery.Execute
Sheets("Sheet1").Range("A1").CopyFromRecordset rs
rs.Close
conn.Close
End Sub
I've played around with the query a lot, and I've been able to get some results by removing some of the AND statements after the WHERE and trying with fewer fields on the SELECT statement, but I need them all in order for this results to work for me. The weird thing is that if I run the same query in a problem like Oracle Sql Developer (after connecting to the DB) it shows the results that I want. I could really use some help, Thanks!
If you are going to hard-code the date range, assuming announcement_date is a date, you'd want to compare against dates, not strings. You can use to_date with an explicit format mask to convert a string to a date,
sta.announcement_date >= to_date( '01-January-2015', 'DD-Month-YYYY')
or you can use a date literal which always has the format YYYY-MM-DD
sta.announcement_date >= date '2015-01-01'
My guess is that your code seems to work in SQL Developer because you happen to have configured your NLS_DATE_FORMAT to be 'DD-Month-YYYY' in SQL Developer.
In reality, you should really be using bind variables rather than hard-coding things like the date range. Assuming you bind a date value, the conversion (if any) from a string to a date would happen in VB and wouldn't depend on your session's NLS settings. There are also performance and security reasons to prefer bind variables.
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
