Re: Template class and const parameters

replace LPCSTR with LPSTR.

you instantiate a DataList specialization on char* parameter, but you send incorrect parameter type to AddNode().

AddNode expect constant instance of type T (therefore, constant pointer to char, or char* const),
but you send a pointer to constant char (const char*).

although the syntax looks similar, semantics is quite different. please look it up in language reference.

hope this helps

of course, be aware that literal strings can't really be modified because they are placed in protected part of memory (executable image), so if you write

LPSTR str = "Hello"; // Const char string       <br />
str[1] = 'a';

you will get an access violation.

I think its because you are declaring:
DataList<char*> data;
And then using LPCSTR with it.

A char* is a pointer to a list of characters, terminated by NULL, while LPCSTR's declaration is:
typedef CONST CHAR *LPCSTR, *PCSTR;

I think changing DataList<char*> data; to DataList<LPCSTR> data; etc should solve the problem.

this is this.

Why don't you just shutdown Windows, instead of try to kill it's vital processes? Confused | :confused:

Yeah you can kill the these process, but for killing that process you should be havinf SYSTEM priviledge.. Only services running in your computer can run on this priviledge.

Thanks Alok, Even if U have those privileges(me not very sure abt this privileges) U cant kill SYSTEM processes since they are necessary n if U will kill it manually from TASK Manager Ur PC wud get rebooted.
But anyways, I got the solution, like GetLastError() returns me "E_ACCESSDENIED" error and thats OK wid my appln Smile | :)

AFAIK, I myself created Service that can kill these process.... secondly at that time my system don't get rebooted but it get unstable.. and Windows Reexecute this process to make system stable....

Check out that software at http://www.securenm.com, i am not sure that site is still up

Calm Down MADAME, sorry if I sound rude.. have you ever heard about SERVICES...? if not let me explain them, they are normal exe but with speacial features, they don't need any user account to run it, i.e. it runs under SYSTEM ACCOUNT, ever before you login your PC (yeap)...

So I hope you got my point, I just want to provide you information, MADAME.. Just a community service....

Relocatable DLLs

Hi Everybody,
1.What are relocatable dlls exactly?
2.Under what condition one had to use them?
3.How they differ from standard Windows DLL

Thanks
Abhi Lahare

Hi there,

1) a DLL normally contains information about where the OSLoader has to map it into the Adress space of an application. If the space is already occupied the system needs to relocate the handle of the Library so it can execute properly.

2) actually you don't have to use them, cuase the system does it for you

3) this depends on the Dll, but normally they should differ that much

Me again,

maybe you want to download and install Sysinternals Process Explorer. It has a view for the modules loaded by an application and you will be able to observe relocated dll's as well.

hi,

i am facing some problem ,while retriving the resource from dll. That dll is a "esource only dll". Here is the code,what i am using.

HMODULE hmod;
HRSRC hr;

/*here testdll.dll is the dll created for testing purpose and it has bitmap1.bmp resource*/

hmod=::LoadLibrary("testdll.dll");
hr=::Findresource(hr,"bitmap1.bmp",RT_BITMAP);

if(hr==NULL)
MessageBox("This is not working");

MessageBox("This is Working");

This is code i have written ,but when ever i run,i get only "This is not working" messagbox. This is means we unable to get the resource from dll.

Can you suggest me, possible solution
