Hi every one,
I meet a trouble.
When i installed my applicaiton on a clean win2k. It terminated every time when it execute:
"pws->Create(wsName, UserName,"");" ,
pws is a CDaoWorkspace object.
But after I installed the "Application Performance Explorer" in "Visual Stutio Enterprise tools" on this platform, then My application works well.
What is the different after I install the tool?
What should I do in my installation?

You got a new set of dlls. One or more of them was different. If you want to move this program to other machines, you will need to find out which one. Use the DEPENDS.EXE program that ships with Visual Studio to get a list of the dlls your program uses. Then look at the versions and dates. Compare them with what is on a "clean" system. You will see a differnece.
Hope the helps,
Bill

Pleas help! I know nothing about Databases
I have an MFC Dialog app that connects to a Access database. I found some great code here www.codeproject.com/database/readdb.asp and this works fine but it only shows how to read from a database. I need to send data to the database from my dialog app as well as read. If anyone knows how to do this using the same structure as in this demo I would be really really grateful!
Thanks,
Alan

Hello all,
does anyone have any experience with MS Flex Grid?
I want a simple, MS based, lightweight grid control that allows me to:
- display tabular data
- sort (numerical, dates, string)
- dispaly boolean values (checkbox)
- edit the data
- Show cell focus selection
There is a lot of great information on how to customize the standard MS
list control, but was wondering if MS Flex Grid can be used instead.
If someone knows about a good documentation, please let me know.
thanks

With the exception of the checkbox, MSFlexGrid will do all of those things. It might even do the checkbox, I've never tried it.
Hope this helps,
Bill

Maybe a simple question for the most of you... 
How can I force to open a menu in a menubar without using the mouse?
I´ve tried this...
RECT rect;
int nCnt = 0;
::GetMenuItemRect(hWnd,hMenu,nCnt,&rect);
::SendMessage(hWnd,
WM_LBUTTONDOWN,
(WPARAM)MK_LBUTTON,
MAKELPARAM(LOWORD(rect.left),HIWORD(rect.top)));
This should open the very first menu in the menubar (typically "File" menu), but it doesn´t work...
Any ideas?

You should look up the TrackPopupMenu API call.

Hi,
How to calculate the date and time in different timezones? How to convert a specific Standard Time to localtime in different timezones? With localtime API we will be able to do that for current timezone settings. But if we want to find out the localtime for different timezones (e.g. EST, Pasific, Mountain etc..), is there a way to achieve that?

Get this from MSDN:
if( _putenv( "TZ=EST5EDT" ) == -1 )
{
printf( "Unable to set TZ\n" );
exit( 1 );
}
else
{
_tzset();
printf( "_daylight = %d\n", _daylight );
printf( "_timezone = %ld\n", _timezone );
printf( "_tzname[0] = %s\n", _tzname[0] );
}

I am very puzzled by this one. Previously, when one wanted to have a custom enum in the typelib, he simply put it in the library section of the idl file:
library SomeLib
{
typedef enum { someval } MyEnum;
}
and voila.
But with VC.NET, and attributed C++, how do you do that??? I tried the following:
[module .....];
[export, public]
typedef enum { someval } MyEnum;
but the declaration is not part of the typelib, since it is before the library statement in the generated idl file.
Anyone have tried this before? Is it still possible to do it? Do I have to switch back to non-attributed C++???

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

Hi all,
I wish to malloc a large char array (to handle appr. 1 MB file sizes), how can I do that without cracking my computer wide open?
/Tommy

If you absolutely need to have a contiguous block of memory of 1MB, go ahead and request to malloc a block that big. Chances are there'll be no serious problems, as 1MB is handlable by PCs these days, and moreover the virtual paging mechanism will help liven things up.
Apart from this, maybe you can get by with some block of memory that grows on demand, so that only gets to these huge sizes when actually required. If so, have a look at std::vector, which automates this behavior for you.

Joaquin is right!
Better allocate the memory as you need it:
with malloc and realloc I normally use! So you don't have to allocate on 1MB up front!

Malloc will work just fine with one warning.
The only problem I have ever run into with allocating large blocks of memory is that if you allocate/free that block a lot, you run the risk of fragmenting your virtual address space. This can happen if you free that 1MB block and then part of it is used by a smaller allocation. Then when you go and try to allocate 1MB again, the system has to allocate a new 1MB block.

Have you considered memory mapping the file? Not only is this faster than reading the file into a buffer, but it will be read into memory on demand (as you access the different parts of the file).

Nope, haven't... How do I do that?

CodeProject may have some examples, I am not sure. Look through the help for the function MapViewOfFile(). Richter also talks about memory mapping in depth in his book advanced windows programming.

In the VC6 IDE it was simply Alt-Enter, Down arrow to HTML. I haven't been able to figure out yet how to ask the VC7 MDE to color .shtml files. (It does .html automatically)
