Hi All,

I am getting an error message saying
"LoadLibrary (abcd.dll failed) - Recursion too deep, Stack overflowed" while registering a COM dll. Can anyone tell me what the problem could be?

Thanks and Regards,

I would try if you can load the dll with depends - tool (part of sdk).
This tool will show you if all dependend dll's can be loaded and will report which dll is missing.

Another thing is trying to register the wanted dll by using commandline tool regsvr32 dllname
This will register the com components in registry.

Your dll may tries to register itself when loaded.

This is only happening when im using a particular function from a library linked to this dll.

Can anyone tell me what the reason could be?

Hello all,

Is there a way to checkpoint a windows process(User Process),rather than just suspend/resume.

What is the core API to be used?

Mention websites which will be of more helpful in this regard.

Thanks in advance.

Perhaps you're after a profiler. MSVC 6 comes with one so I assume the newer ones also do. There are also third partly ones like NuMega’s TrueCoverage.

When using CDaoDatabase and CDaoRecordset class.

Hi,

CDaoDatabase and CDaoRecordset is good choice.
In the connection string specify the username and the password.
For more information check this link

I found the method at following link.

Open with password

Thank you your help Smile | :)

Remarks

You must call this member function to initialize a newly constructed CDaoDatabase object that represents an existing database. Open associates the database with the underlying DAO object. You cannot use the database object to construct recordset, tabledef, or querydef objects until it is initialized. Open appends the database object to the associated workspace's Databases collection.

Use the parameters as follows:

* If you are opening a Microsoft Jet (.MDB) database, use the lpszName parameter and pass an empty string for the lpszConnect parameter or pass a password string of the form ";PWD=password" if the database is password-protected (.MDB databases only).

* If you are opening an ODBC data source, pass a valid ODBC connect string in lpszConnect and an empty string in lpszName.

For related information, see the topic "OpenDatabase Method" in DAO Help.

Hi,
I dont think you can get some handlers for toolbar doubleclick,but i got an idea:-
1) Map the WM_COMMAND
2) put a static boolean variable inside it at the first click make it true and set a timer .
3) The timer will be to trigger at a fixed time(the time for the second click) nothing hapens in that time set the static variable back to false .
4) kill the timer .

Hope this helps .

Regards,
FarPointer

I'm looking to create some sort of database. I need to store details for students and divide them acording to year and class. Having never dealt with any for of database before I'm not really sure how to proceed. My project currently has Excel functions built in, but I'm not sure if storing something like this would be efficient enough using Excel.

Any ideas or suggestions? What databases are easy and fast to learn?

Can you use SQL . for any db you invariably need SQL

Once u know SQL its upto you to decide which db to go with depending on issues like distribution etc . There are embedded (text file) based databases available that are SQL compliant .

One good db is sqlite

Is there any way to make a string accept two words separated by a space?
So far, I have found that the string only accepts the first word and rejects any input after the space.

Thanks.

don't confuse NULL with Space... NULL terminate String and SPACE actually defined as Char(32)

actually, i wanted to send multibytes to the machine, like 02 00 02 00 20 42 51 08 to a function through which we could send this data to a machine, but i am able to send one byte at a time, how is it possible to send all the bytes at a time to a function?

Use the send() function on one end and recv() on the other.
