Hi to all,

I am having more than 20 dlls for my application. if i want to store those dlls in one folder and use them while running the application what i have to do?

For example all header files if I copy in one folder and giving this folder name in include folders of Tools->Options then it works fine. Is there any method like this for Dlls. Please help me.

Thanks in advance.

ActiveX Controls Test Container saves file as .tcs. If Activex Control is placed anywhere in container and save it and next time if we open that .tcs file activex controls are placed on same locations as it was at the time of saving in .tcs file. I want to implement this functionality (drag & Drop of activex controls in application)in my project. so how should i do this or if any other solution is there for this problem or if anybody could give me file format of this .tcs file of ActiveX Controls Test Container.

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 | :)

When i killed that application ... My system get unstable, not rebooted and after some time as precaution measure Windows have restarted these process with new PID.

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");
else
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

You cannot reference the resource by its name ("bitmap1.bmp"). You have to pass its resource identifier to FindResource. Refer to your resource.h, to find out which identifier was assigned to it and use this call:

hr = ::FindResource ( hmod, MAKEINTRESOURCE(%YOUR_IDENTIFIER_HERE%), RT_BITMAP );
