Why do you want to do that?
Can't you prefix with an alphabetic char the numbers?

Hi,
I am having a SafeArray of bytes .I should know the size of it.
Is there any way where we can get the size of safearray?
Thanks
Today is a gift, that's why it is called the present.

My suggestions - look up the following functions:
SafeArrayGetDim(...)
SafeArrayGetElemsize(...)
SafeArrayGetLBound(...)
SafeArrayGetUBound(...)
Get The number of dimensions using the first function, use the third and forth ones to determine the number of elements in it. Use the second function to verify element size (size == 1 if using BYTEs/chars).
Peace!

The pidlRoot parameter of the BROWSEINFO structure is used for that.
Do a search for that member and you will find ways to manage the ITEMIDLIST required for the structure.

yes, i know that james, sorry for not having pointed out my tries.
actually, i called CoInitialise(NULL) first, and i tried to use SHParseDisplayName() to create a PCIDLIST_ABSOLUTE to give to the pidlRoot attribute of the structure, in vain

Have you supplied a callback function? That is where you establish the default folder.

hu, no ! i thought callbacks were only to extend the dialog style/events management...
Sir, can i ask you please to show me how you write such a function ?
thank you very much for your answer

You can use it for whatever you need.

I could, but Googling for examples would prove a much more useful exercise.

When I delete directory which contains some files I will not get message FILE_ACTION_REMOVED. This happens int XP professional SP1. I can't install SP2 because some others reasons.
My code

Have you tried the sample application from CDirectoryChangeWatcher[^]. Still nothing? Do you have the same problem? Then you really need to update to SP2. Sorry, but good luck!
|
|
|
|
|
I tried this demo, but on the machine, where my code doesn't work this demo doesn't work either. it really sucks.
|
|
|
|
|
You should read this[^] first.
Do take a look at point 4 and 5. 
|
|
|
|
|
|
as required by the administrator here[^] (see 5.), please edit your message (not posting a new one) and post the code samples inside <pre>...</pre> html tags...
thank you

In my program iam using a named pipe for reading from source to destination programs. but when the source is waiting for input from destination(via another pipe) i cant read from the pipe .Only after the input was given ,the reading is possible.
Can I use any other technique by replacing pipes.
(Source and destination programs are at same machine)

you can use select system call or do non-blocking IO using fcntl system call.

you can check whther there is data present on the pipe or not
bu calling PeekNamedPipe() api so that you can come to know data is
available or not!!
and then make ReadFile() call is data is available
i did not understood your problem very well but this can be your solution
so replied

As a simple trick you can assign size 0 to the intended columns,
using SetColumnWidth( nCol, 0 )
It works, but the user can enlarge the columns if he wants...

excuse me, but from 0 to 7, it gives you 8 ones !!!

Hi,
In a current tool, that copies Sources from a server, zips them and sends the zip-File to another server, I have to delete the intermediate zip-Files stored locally about after a week (so that they still are available if the recipient claims a transfer failure).
I can't use CTime procedures for determining that week as the tool itself was created as Win32 console application without MFC support, so I tried to get the Local Time with GetLocalTime(&now), convert this to a FILETIME and compare it with the FILETIME got from the creation date of the file to decide wether this file is to be kept or deleted. According to the help pages FILETIME holds intervals of 100 nanosecond, so a week would calculate to 7(days)*24(hours)*60(minutes)*60(seconds)*1000(milliseconds)*1000(microseconds)*10(intervals of 100 nanoseconds) = 6048000000000 intervals.
The help pages tell me that I have to copy the FILETIME to a LARGE_INTEGER before I can compare the dates so I tried the following code:
LARGE_INTEGER liNow,liFile;
liNow.LowPart = ftNow.dwLowDateTime;
liNow.HighPart = ftNow.dwHighDateTime;
liFile.LowPart = localDateCreated.dwLowDateTime;
liFile.HighPart = localDateCreated.dwHighDateTime;
if(liNow.QuadPart - liFile.QuadPart > 6048000000000)
{ ... }
Now I have the problem that none of my files reach the deletion part of the code, even files two weeks old only have a difference of 1604372500. Is something wrong with my calculation, my conversion to LARGE_INTEGER or is the whole approach faulty?
Hope anyone can help me

How do you obtain the creation time of the file?
