There is a CryptAPI in windows which you can use. It will be better than anything *I* can write. And if you're asking the question, it will be better than anything *you* can write either.

Modified: Might be CryptoAPI. CryptAPI would be controlling the undead.

In your first sentence, you claim to already have such an application.

Hello all,
My reqirement is to download .CAB file containing OCX, EXE, INF files over net from specified URL. Having been downloaded .CAB file, it shold be self extracted and in turn call .exe on client machine That is, it should be autorun. If my OCX and exe is already there on remote machine then it should not download again and run existing one.
Please help me out. Any help is highly appreciated.
Thanks & Regards,
Hemang

What are you struggling with? I assume you've done some work already.
Can you download files? Can you extract files from CABs? Can you use CreateProcess? etc.
You're question needs to be broken into bite size chunks.
Good luck,
Iain.

I want to download exe and run that exe from decided/desired default directory(C:\Windows). But i am not able to download it. I also require WSOCK.dll for my EXE. I am attaching my INF file code snippet to make things clear. I hope that from this code snippet you will be able to understand and help me out.

Perhaps you could show us what you have already tried to code, from there we may be able to point you in the right direction.

I have made an Activex control using MFC Activex Dll. Then I tried to call an EXE from that ActiveX.
For that I made cab file containing my OCX, EXE, dll, and INF files. Then after i tried to download an active control by using HTMl file located on some web server. This should extract cab file and in turn install and run EXE to and from desired location which i set from INF file. It is most probably C:\Windows. now can you tell whether i am folllowing correct path or not.
Thanks & Regards

So why bother with anything else until you get this one piece figured out? Don't intentionally over-complicate things.

Hi,
I wrote some class that derived from the class CDialog.
In my new class i have some object control on some CList.
I also have some other class that have pointer to this CDialog - and in some place in the code - i call Create method of this CDialog - and ShowDialog.
Until here all work find. But when i press button RefreshList that belong to the derived class i see that the CList control object is null and i don't understand why
Can someone help me ?
Thanks

Do you mean CList as in a list of objects, or CListBox / CListCtrl?
If it's a list - do you mean NULL, or just empty? If it's NULL - then why are you using a pointer? And at what point do you create a new List to point to? If you don't create one, then of course it's NULL.
If you mean it's empty, then do you put things into it? And if you do, look for any code that removes them.
If you mean a control, then you need to point the object at a window. Look up DDX_Control in the help files for information.
Iain.

Do you have any call this object of other place except this dialog?
|
|
|
|
|
No - only calling this object in pressing dlg button ( in same class )

So did you use of pointers on your project?

Hi all
I have a rather strange requirement . My current feeling is Shell Programming but not sure what I have to do ..
Well ,
Is there any way to launch IE proxy setting dialog(IE->Tools menu ->internet options->connections tap ->LAN settings) from .net application ? the requirement is proxy setting dialog box alone should popup(not along with IE) if we click a button in the application. In fact I saw some Win32 APIs like WinHttpGetProxyForUrl ..are avilable to get/set the same but I prefer the "original IE dialog" to appear and get set .
Could any of you please throw some light on this ? Is it possible in the first place ?
Thank you in advance for your help.
regards
Bala

Hello everyone,
1. Generally speaking using GetProcAddress through ordinal is faster than through name, right?
2. Why?
thanks in advance,
George

If you mean that strcmp is slower than indexing an array I agree. But I don't think this kind of optimization really matters in applications.

Thanks CPallini,
I ask this question only for pure technical interest. Do you mean in your experience or in theory by ordinal is faster? Why?
regards,
George

I've no big experience of DLL calls via GetProcAddress since I usually use load time linking approach.
Anyway I never experience performance issues.
My previous post points out that lookup using integers is usually faster that the one using strings, but, IMHO the performance improvement is usually negligible.

This is going on my arrogant assumptions. You may have a superb reason why I'm completely wrong.

Thanks CPallini,
1.
You mean you use implicit linking to link with import library?
CPallini wrote: use load time linking approach
2.
If we use the approach as you used above, to link with import library, in this approach, there is no ways to use by ordinal technique?

George

No, as the functions will be called via the linked stubs in the library.
I have never tried to explicitly load a DLL which has already been loaded by its lib.
Let's think the unthinkable, let's do the undoable, let's prepare to grapple with the ineffable itself, and see if we may not eff it after all.

Thanks jhwurmbach,
From your reply, I understand by ordinal only works when we use LoadLobrary, if we use implicit linking, there is no way to use by ordinal.

George
