check for the existance of the registry key for excel.applicaion:
HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{00024500-0000-0000-C000-000000000046}
before calling the code to create the Excel.Application object.
If the key is present, it should beok to open exel, if not just skip.

Without seeing the code that throws this error and knowing which line it fails on, it's pretty much impossible to tell you what happened.

There doesn't appear to be anything wrong with the code, but you left off the code that opens the connection to the database, including the connection string.
Other than that, it would appear that you have a problem with the database itself. Either you don't have the appropriate permissions to database objects required to fill this SELECT request, or the database is corrupt, which if it's an Access database is entirely possible (not so much for an SQL Server database).

yes,i'm using access. i have rename the one table inside it, i think this cause the error. thanks, i will check for my database.
|
|

Your code didn't say anything about renaming a table. If you renamed the table in the database, but didn't update the code to get it's information from the table using its new name, then of course your code is going to fail!

I am currently working on a data import application that will write a file to a SQL database table. I need to write a function that will pass two parameters: partnumber and format style to format the partnumber. Need ASAP!

If I were you I would start writing it, then. The sooner you start, the sooner you'll finish.
If you run into any problems with it, you are very welcome to post a question here in the message board.
Good luck.

A function that will format the file part number based off format code.
|
|
|
|
|
Which means what? Geez - You're not helping much are you. You need to help us to help you. Explain what you want to happen.
|
|
|
|
|
That doesn't mean anything. The file get's it's format when you write it and how you write it. I still have have a clue what you're trying to do.

Hi
How to show Tooltips for a control when it’s disabled?
Thanks
|
|
|
|
|
IIRC, ToolTips are disabled along with the control. I don't know of a method to get around this.

Dear All,
I have a problem, I have a DLL that runs a Recieve Thread for USB communications. I am calling the DLL from VB 2005. It all works (openUSBComms function, and recieve data using a Callback). However When I call the closeUSBComms function from the FORM CLOSING event my program hangs.
In side the DLL, the Close Functions Sets a 'Death' Event and Waits for the Thread to terminate using WaitForSingleOject.
When I call the dll closeUSBComms funciton from a Button event say, all is well and the Thread Terminates, But when I call it from the Closing Event of the Form the WaitForSingleObject doesn't return and the Thead doesn't terminate.
Any Ideas why ?
I have access to both the VB and the DLL source code and can change either. But preferably not the DLL unless really have to.
