Thanks.. Rane. But it is not working. Any user creating directory should be able to give access permissions to any other user , that is my task.

hi,
I am using CMap To store data in the form of a structure. Before pushing the data data CMap finds that whether the data with specified key is presnt or not. If it is not present the it is Set.
Now what i want is that if the data with some key exist and u are having some new data for the same key then the original data should be replaced with trhe new data in the CMap.
Here is my code
Please tell what to do.
void CMainDlg::FillDetailsinVisitorsMap(VisitorDetails stVisitorDetails, CString strSessionID)
{
if(m_mapVisitorDetails.Lookup(strSessionID,stVisitorDetails) == 0)
{
// NOT FOUND IN MAP
m_mapVisitorDetails.SetAt(strSessionID,stVisitorDetails);
}
}
Thanks in advance.

You should consider hiring a software developer.

Definitely.

Did you read the function documentation ? This is done by default:
First, the key is looked up. If the key is found, then the corresponding value is changed; otherwise a new key-value pair is created.

Hi masters!
-----------
I'm writing a system-wide keyboard hook. I've an EXE that calls a function
named "InstallHook()" from a DLL, passing it's current thread ID through it
(say dwThreadID) ...
Within DLL, I've a general variable named g_dwThreadID that will be equal to
dwThreadID (mentioned above) ...
The problem is:
----------------------
Although g_dwThreadID has a certain value within the DLL initializely,
but it will be equal to zero! I guss It's because the DLL is mapped to every
proccess in the system and then all variables, including g_dwThreadID gets
initialized ...
Now I'm looking for a way that I can share initialized g_dwThreadID among
all loaded instaneces of my DLL ...
Any help?

Hi
I try to explain better the problem.
I have a black and white bitmap , and I found algorithm to detect the edge between the 2 color ( Sobel algorithms ). Now I have a list of pixel that describe the border ( edge ) of the image and I need an algorithm to approximate the list of point with a set of lines.
At the end I need an algorithm to convert a Bitmap file to a Plot file , or better I need to convert a Bitmap to a CAD/CAM path description of a cutter.
Thank

What about CodeProject's article search engine

I have an issue when computing how long a Unicode string is when it is actually displayed on screen. For example, you might have a 30 character Thai string, but when it is actually displayed, some pairs of characters result in a single character on-screen, so the result might only 'look' like 20 characters. What seems to happen is that two characters sometimes result in a character with a 'mark' above it (like a European accent character).
Because of these potential pairs, logic I have that currently uses _tcslen goes out of the window. I tried experimenting with the GetCharacterPlacement API call but didn't get very far. The strings all display correctly, but I have to know the 'display length' when forcing a fixed number of characters-per-inch (don't ask!).
Is there a way to find this out?
