Hey guys, I'm having a problem with the code below. When it gets to the following line: Code: lstTeam.ListIndex = rs!fldTeamNum I get the following error: Run-time error 91: Object variable or With block variable not set. Yes, the objects exist. Remming out that particular line just causes it to occur at the next line. Remming out both those .ListIndex lines avoids the problem altogether. I've set the variables required further up the food chain, so I know that's all fine. I've also used this quite successfully in the past. I'm scratching my head trying to work this out. (Oh and BTW I know this is probably not the best way of doing it, and I still have some debugging to do, so bear with me on this one...) Code: Private Sub cmdSearch_Click() If txtSurname.Text = "" Or txtFirstName.Text = "" Then MsgBox "Please enter first and last names to search for.", vbOKOnly Exit Sub End If Set ws = DBEngine.Workspaces(0) Set db = ws.OpenDatabase(DatabasePath & "ao.mdb") Set rs = db.OpenRecordset("SELECT * FROM tblAuthOfficers WHERE fldSurname = '" & txtSurname.Text & "' AND fldFirstName = '" & txtFirstName.Text & "'") If rs.RecordCount = 0 Then MsgBox "Not found." Set rs = Nothing Set db = Nothing Set ws = Nothing Exit Sub End If OfficerNum = rs!fldKey lstDepartment.ListIndex = rs!fldDepID lstTeam.ListIndex = rs!fldTeamNum If rs!fldPhone <> "" Then txtPhone.Text = rs!fldPhone End If Set ws2 = DBEngine.Workspaces(0) Set db2 = ws2.OpenDatabase(DatabasePath & "ao.mdb") Set rs2 = db2.OpenRecordset("SELECT * FROM tblSubDepartment WHERE fldDepID = " & Left$(lstDepartment.Text, Val(Left$(lstDepartment.Text, InStr(lstDepartment.Text, vbTab))))) While Not rs2.EOF lstSubDepartment.AddI

If frmForm is the form where this code resides, you need to use Me.Controls instead of frmForm.Controls.Also, since you are using .NET, never use the "ON ERROR" code. That is soooo VB6. Look into how to use Try and Catch instead. Your code will behave better and be easier to manage. RJ :thumb: MCSD {My faqs.} It's not a bug--it's a feature.

I can make a nero error number 91 object, and use it's methods and properties...... but that will only work on machines that have the Nero libraries installed. If it's not installed, when you try to make the object (either through early or late bindings with new or createobject), the variable that SHOULD refer to the object is still set to Nothing, because the library failed to create an instance of the requested class..... Basically, you are trying to make an object from a class that doesn't exist on the NT box. 0 ibrahim refaat 9 Years Ago when i want to setup certain program this messege appear 0 PVBert 9 Years Ago in vb ide build an exe file get a dependency walker and check which dependencies are needed for your exe file create those dependencies on youre target machine OR get a setup (e.g. setupfactory) tool that builds a setup which does this for you it can make a cabin file on development machine that you can deploy on your target machine 0 akodalikar 8 Years Ago According to the MSDN library...

which may occur randomly on your system. This error is specifically caused by programs which try and use the DCOMCnfg.exe file on your computer - as this file is often damaged, corrupted or unable to be processed as reliably as possible. If you are seeing Runtime 91 errors, it's highly recommended that you are able to fix the various problems which can cause them to show. This error will typically show in this format: "Runtime Error 91: Object variable or with block variable not set" Runtime Error 91 is usually not seen when the software is installed, but it appears when one tries to use the installed software. The error 91 normally occurs when a link of the software that is being downloaded is interrupted or missing. The bottom line is that this error appears when you use a program on your PC, and there are a number of issues with the "variables" inside it. Every program you use has a set of options inside that are known as "variables" to programmers, and because each of these options needs to be coded manually - it's often the case that many of them will either become damaged or corrupted. To ensure this is not causing any issues on your PC, you need to be able to repair the various settings which could be causing issue, as well as fixing any other problems on your system. Fixing Runtime Error 91 Easily To fix runtime error 91, you first need to fix the DCOMCnfg.exe settings on your PC. This program is used to control various file permissions on your computer, as well as helping to load up a series of different programs on your system. Unfortunately, this program will continuously cause errors on the typical Windows computer, as it's continually being damaged and corrupted. This is the main reason why the runtime 91 error will show, and to fix it, you should ensure that the DCOMCnfg.exe file is set to allow "Everyone" to use it. Fixing Runtime Error 91 with Tool You should use a PC Optimizer like Total System Careto scan through your PC and repair any of the damaged settings which could also be contributing to the Runtime error you're seeing. Total System Carewill fix errors inside the "Registry" of y
