RIght now, the only registry keys are both done through the setup project in Visual Studio -- adding an association for my app's file extension in HKEY_CLASSES_ROOT, and the other one being the MimeType in the Content Types keys (HKEY_LOCAL_MACHINE/CLASSES/MIME/DATABASE/CONTENT TYPE/)

However, none of these registry entries are sufficient to automatically send the file type from Internet Explorer to my app -- currently that has to be done by the user, which is what I'm trying to change.

Edit control focus locks application

At a minimum, here are the registry keys/values you'll need. This example, timfox.exe, uses files with a .fox extension.

HKEY_CLASSES_ROOT\.fox = TimFox.Document
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\command = TimFox.EXE %1
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\ddeexec = [open("%1")]
HKEY_CLASSES_ROOT\TimFox.Document\shell\open\ddeexec\application = TIMFOX
; note: the application is optional
; (it defaults to the app name in "command")

HKEY_CLASSES_ROOT\TimFox.Document = TimFox Document

Hi,

I have a simple dialog box that has an edit control. I want the dialog box to come up with the cursor in the edit box ready for input. I can do this using myDialog::UpdateDialogControls(pWndCtrl, TRUE) but then the focus is locked on the edit control and I can't use the OK or CANCEL buttons and I have to use the task manager to end the application. I have also tried the GotoCtrl(pWndCtrl) with UpdateData() and UpdateWindow() and some other variations that seemed like they might work but they have no effect at all. This is probably very simple, I just can't seem to figure out the right command sequence.

There should be a SetFocus() function you can use.

The first control on the dialog that has an id other than IDC_STATIC will automatically get the initial focus. Otherwise, you'll need to call SetFocus(). If you opt for this, be sure and return FALSE from OnInitDialog().

Thanks,

Although it would seem that GotodlgCtrl(pEditCtrl) followed by SetFocus() should do the trick it doesn't. It needs to be in the syntax of GotoDlgCtrl(pEditCtrl->SetFocus());

I've read a lot that to make your window non-resizable that you need to remove the WS_THICKFRAME style, but I can't find here on Code Project, or MSDN, really how to do that. Can someone help me out?

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.

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));

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!

Jim Crafton1-Dec-05 7:51

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.

Jim Crafton1-Dec-05 8:29

1-Dec-05 8:29

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

1-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().
