Re: Remove WS_THICKFRAME style

1-Dec-05 7:48

CAll GetWindowStyle() to retreive the style for the window.
Then mask out the WS_THICKFRAME ( style = style & ~WS_THICKFRAME );
Then set the windows style with the new style mask using SetWindowStyle().
THen call SetWindowPos(hwnd_, NULL,0,0,0,0, SWP_FRAMECHANGED|SWP_NOMOVE|SWP_NOSIZE);
This will cause the window to be updated properly so that the style change is reflected visually.

Thank you both. The other answers I've read were much more complicated, so much thanks.

Implement SQLXML Bulk Load using C++Implement SQLXML Bulk Load using C++

Hi ...

I am trying to bulk load xml into sql server. This seems to be a relativly easy thing to do using the SQLXML COM Component. I am having trouble finding documentation on the SQLXML COM Object model. Also I have found samples in C# and VB ... I need my implementation to be using C++. If you have any sample code or a like you can send me to that would be create.

A good example of the type of doc that I am looking for is the object model for the MSXML COM Component
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/wceappservices5/html/wce50grfxmldomobjectsinterfaces.asp
Is there such documentation for the SQLXML COM

Below are the links I have used to date:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dnanchor/html/anch_sqlxml.asp
http://www.dbazine.com/sql/sql-articles/cook3
http://www.perfectxml.com/sqlxml.asp

Some code:

The code below uses the IXMLDOMDocument2Ptr interface and then trys to
use the SQLXML using the SQLXMLOLEDB Provider. Again, I need some doc
or samples on how to use the SQLXML COM Interfaces or the
SQLXMLOLEDB Provider in C++.

The code will fail on the following line
pCmd.CreateInstance(__uuidof(SQLXMLBulkLoad));

void CTestApp::OnTestMsXmlTest()<br />
{<br />
    // Define ADO connection pointers<br />
    _ConnectionPtr pConnection = NULL;<br />

I need to implement a function to read application event logs in realtime. I have done this for our Unix server in Perl, but do not have the option of installing Perl on our Win32 production servers.

I have scoured (literally for days) the internet looking for any information on the best way to do this in C++ but haven't found anything! Any assistance or direction is greatly appreciated.

What I need to do is read these event logs and then send alerts or trigger other functions based on specific events. The log files are updated 10-100 times a minute depending on how many users are connected to the server so I need to continue monitoring the log even if I fork out to respond to event01. Make sense?

Thank you!

Sounds like you want to create an Event object ( see CreateEvent()[^]) wait on it in on place (thread) and then signal it from another when the log write occurs.

You can look into NT's event logging API's but I don't know if there are any performance issues for what you're intendending.

You can create teh event with a name, so that more than one process can wait on it.

That definately seems to take care of the second part of my problem. Thank you!

Now do you have any advice on the most effecient way to read a log file that is being updated almost constantly? Smile | :)

Well just off the top of my head, if you're worried about access speed/io to the file, you could create a memory mapped file and then use that - then one process can write, another can read, without having to contantly open/close the file all the time.

This is a bit too much C++ as I am mostly a Perl/PHP developer. I was hoping for something that I could do with simple file I/O. =)

I will look into it however.

Thanks!

Jim Crafton1-Dec-05 9:29

Well then you could just open the file, and read from the end of it. Maybe keep track of the file size from the previous open, and compare to it's current size, and then read in the difference from the end. That's slower, and less complex, but makes heavier duty use of disk IO. Don't know how big a deal that is for you.

Actually, memory mapped files have nothing to do with C++. One thread/process will need to call CreateFileForMapping() (all others will need to call CreateFile()). Call CreateFileMapping(), then use the pointer returned from calling MapViewOfFile().

I looked into this, but this seems tailored to logs that use the same format (and actually write to) the windows event logs. Which our system does not.

Thank you, though.

*** I guess I should have been more clear. These are *not* standard Windows App Event Logs, they are flat text .LOG files.
