probably linked list is very slow at searching in compare to other datastructure

sorry, but STL is fully portable, because provided with the C++ language. it's not a Microsoft product 
|

Hi
I used the STL for my work , some time it throw exception while searching (map.find()).
My project is a multithreaded. Each thread had it’s own map.
|
|
|
|
|
were you using STL's std::map<> or MFC's CMap ?
|
|
|
|
|
STL's std::map<>
Not MFC's CMap
eg.
map <string, userdefinedclass=""> mapclass;
mapclass mapobj;
char searchkey[100]={0};
strcpy(searchkey,"somekey")
try
{
mapobj.find(searchkey);
}
catch(...)
{
exception occurred !
}
note :
mostly occurred in Destructor of string class
|
|
|
|
|
and what kind of exception were thrown ?
what were you doing ?
[EDIT]
Do you build your project with mutithreaded DLL (/MD or /MDd) ?

So it threw an exception because you did something wrong, and now you are afraid to use it again. Where's the logic in that?

sounds like intellisense might have been disabled. check your studio settings.
|
|
|
|
|
Is your problem this list?
|
|
|
|

Dear Sir; I am using CSortListCtrl (derived from ClistCtrl);
It is possible to make a particular color to one line ?
|
|
|
|
|
Yes you can set the selection color/text etc to a line.

I want to use List control in my MFC app. But if I use list control in my dialog box, the dialog box is not poping up. Is there anything I need to add? Is there any good document that can be helpful?
Thanks in advance.

Call InitCommonControlsEx() in InitInstance()
|
|
|
|
|
Try calling InitCommonControls() before creating the dialog
|
|
|
|
|
|
main()
{
CStringArray lDirectory;
lDirectory.Add("designer.temp.directory");
lDirectory.Add("designer.mediator.xml");
GetDirectoryPermission(lDirectory);
}
bool GetDirectoryPermission(CStringArray lDirectory)
{
.....
}
it gives me an error
"error C2664: cannot convert parameter 1 from 'CStringArray' to 'CStringArray'"
|
|
|
|
|
When passing a parameter "by value" (in your case the CStringArray object), the whole thing is to be passed, but there is no copy constructor available. That's why you get the error.
Therefore, you should pass the parametter by reference:
bool GetDirectoryPermission(CStringArray& lDirectory)

You are missing something there, that's for sure 
If you are using the project wizard, use MFC SDI Application Project, rather then win32.
Another idea would be that your project should be "multithreaded".

am i missing some Library or header ? My application is not multithreaded. I am not using wizard to make one. initially it was Win32 console application. But to use msxml and all other stuff like CString class its now MFC.
