Getting error:800a0174 while creating instance of COM

Question

I am getting error while creating many instance COM object as shown below.

But not appearing when less number of instance created.

Answer 1

Hi,

Do you have any more details on what kind of COM object this is? Also, could you tell us more about the error (or the code that causes it)? There might be an issue in the code you are using when creating the COM object.

Also, is it important that you use the COM object? There might be an alternative which doesn't require you to use COM. That could help...

Hope this helps

An error starting with 0x8 is a file access protection error or an invalid pointer.  The CSLID is an entry in th eregistry and the application may not be registered properly on your computer or installed which properly on your computer.  YOu also may not have permission to read/write/execute the application.  Here are some suggestions

1) Click on the except link "Copy Exception detail to clipboar".  Then go to any text editor like Notepade and Paste (cntl-v) to view all the details of the exception.

2) Search the registry for the CSLID.  From START on your computer select run.  then in the pop up box type "regedit".  Use the Edit - Find menu to locate the CSLID.  the CSLID will give yo uthe executable that is causing the error.

and in case, it is a web based com component you can try to remove the security pop up option with creating a custom key in registry and assigning a value to it

for example, this works fine for cutome protocol:

Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\ProtocolExecute]
[HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\ProtocolExecute\CustomeProtocolName]
"WarnOnOpen"=dword:00000000
