Object Library Invalid Or Contains References To Object Definitions That Could Not Be Found

May 24, 2009

I get an error while trying to install a third party Excel add-in [Thomson One Analytics]. Error: "Compile error in hidden module: Main" Microsoft Excel 2003..But when I had the Addin unlocked.I noticed that it was getting stuck at a specific line in the MAIN module of the Addin package and the debugger throws a compile error message saying that: "Object library Invalid or contains references to object definitions that could not be found". Earlier when I had this issue,I made another user login to the PC and we were able to use the add-in successfully. But this time even a different user with Admin Rights was not able to use it. [code]

Tried to install and run the Addin on the same computer by a different user having admin rights, no go.Made sure that he references for the add-in in the VBA editor are correct, by comparing them with a working computer, no go Re-installed "Service Pack 6 for Visual Basic 6.0: Run-Time Redistribution Pack (vbrun60sp6.exe)", no go. Ran repairs on Excel, no go Re-installed Excel, no go

.net - DataGridView.Column(ColumnName As String) Gives Error "Object Reference Not Set To An Instance Of An Object"

Jan 7, 2010

This is something that has been bugging me for a while as it is easily fixed but not desirable.I have a DataGridView that has 5 columns. The first is called ID.In vb.net the following line gives an error "Object reference not set to an instance of an object": dgvJobs.Columns("ID").Visible = False ' ERROR dgvJobs.Columns(0).Visible = False ' OK

Obviously using the name is much better than a hard coded value to reference the column but wondering if there is anything i can do to get this to work correctly?The datagridview datasource is BindingSource control with the datasource being a dataset.

Get "Object Reference Not Set To An Instance Of An Object" Error When Trying To Find An Instance In A String?

Jan 23, 2009

I am using the IndexOf function of the string class to find a specific instance of a string. And based on that I have a logic to do something. Below is the example of what I am doing. The code is in production and is working fine. But for some instance I am getting an "Object reference not set error". Yeah its intermittent.The requestXML is a string of xml data passed in as a paramter to a subroutine. I am fetching the xml string as a form post in a request object. The only thing I could think of getting this kind of error is when the requestXML string varia

LINQ Return Single Type Of Object Invalid Cast

Jun 29, 2010

Ok, just needing a 2nd set of eyes looking at this to make sure the error isn't something else other than my LINQ code here.  Here's the function class itself:

Public Function GetJacketByPolicyID(ByVal jacketID As Int32) As tblPolicy
Dim db As New DEVDataContext()
Dim j As tblPolicy = db.tblPolicies.Single(Function(p) p.policyNumber = jacketID)
Return j
End Function

and here is the code which calls this class function in the web control form itself:

Dim p As tblPolicy
Dim j As New Jackets()
p = j.GetJacketByPolicyID(3000050)

For some reason it's flagging the 2nd line in the GetJacketByPolicyID function saying the specified cast is not valid.  So I'm guessing it's something I'm doing wrong.  I'm sure the tblPolicy/tblPolicies class works right since I can create a new instance of a tblPolicy and set a few variables by hand and return it, so that's not it.  I've also checked the datarow I'm fetching and there's no null values in the record, so that shouldn't be it either.

Invalid Character In A Base-64 String?

Dec 15, 2009

Ok, so I got everything working except for one thing. My program stores text in a settings files (which it saves to and encrypts to wonderfully), but it will only work once. For example, I type in an author, title and body, and click Publish, it publishes and is labeled with a "1.". Restarting the application, you get the desired effect, a decrypted string from the encrypted settings file, now publish another entry, this makes a new line with "vbNewLine" and then encrypts it, fine and dandy. Now apon opening the application again, you get an error stating "Invalid character in a Base-64 string.". What do I do?

Runtime Error '380':Invalid Property Value

May 2, 2006

A VB5 program I wrote years ago stopped working and is now giving me this error:

Run-time error '380':Invalid property value

I cannot figure out what has changed, since I run that program almost daily.   It was working fine, then stopped (without any changes to the program).   I suspect I may have uninstalled something it uses, but cannot figure out what.When I open the VB5 IDE, I get an error saying:

'c:program filesdevstudiovbComct232.ocx' could not be loaded--Continue Loading Project?

If I say no, it does not load and I cannot see the source code.If I say yes, it does load and I can see the source code but I get weird compiler errors.

Modifying String Containing Invalid NTFS Filename

May 6, 2009

I have a piece of code to debug. Because of unknown bugs it creates a dummy filename. I want to track all the pieces of code who fires that creates the dummy filename, so I can change the dummy file creation to a thrown exception. Since I the dummy filename is stored on a string, I plan to modify that string to contain an invalid NTFS filename, maybe containing invalid chars. Is there a reason to prefer some invalid chars over others? There are some predefined invalid NTFS filename destined to this purpose? (I may think of AUX , COM1 , LPT1 or PRN , but those names run the risk of start sending data to a port instead of throwing an exception).

VS 2008 - Apparently Invalid Connection String

Mar 20, 2009

Before I explain, the connection string I am trying to use is copied directly from elsewhere in the application that has always worked and still does.
Provider=Microsoft.Jet.OLEDB.4.0;
Data Source=|DataDirectory|cdb.rmd;
Persist Security Info=False;

My problem is that no matter if I go to "Server Explorer", "Data Sources", or any other option it will not let me add a datasource/database. Up to this point I have done everything at runtime but now due to reporting issues I need to create a dataset in design view.

This is what happens:
I click "Add connection..."
I choose "Microsoft Access Database File" (Which it is...)
I click "Continue"
Form shows up with a field for my connection string, which I insert (shown above).
I click "Ok"

I get the following error:
Format of the initialization string does not conform to specification starting at index 0.
The "Test Connection" button is apparently useless as the connection passes even if the field is blank.

I have attempted reducing the connection string to only what is absolutely necessary.
I have copied the string directly from connectionstrings.com replacing my filename.
I have renamed the file to an .mdb extension.
I have used the full path from C: all the way to the file.
