Memory allocated between two checkpoints by a process

BadJerry11-Feb-10 7:30

11-Feb-10 7:30

I need to find out (in a release version) how much memory has been allocated after loading (a large) object - the object itself is loaded by a DLL (if that's relevant). I am looking at GlobalMemoryStatus but not sure sure which properties I should use to get accurate information...
Help welcome!

Multi Monitor Configuration in MFC/C++

Hi,

I am starting a project where in I have a dual monitor setup for shown objects.My project involves showing squares, circles, lines on the screen. I use the primary monitor to control the attributes and the second monitor solely for display. I have issues setting up these two windows/frames; one in each monitor using MFC app wizard. I am at loss as to which model I should use: SDI or MDI. Any ideas, pointers to existing projects, directions are more than welcome..

rgds,

As a final user, in general I hate when an application want to decide itself how to set the the spaces into my desktop.

Unless you are in a very captive environment (PC running your application only, may be on a synoptic etc.), the best way is to operate on two different frames and let the user to decide where those frames must go and how they have to be sized.

What you can do is save the frames positions (may be in registry, or in a "state file", into the user data directory) so that they can be placed the same among different invocations.

Using SDI or MDI is than much more a matter of the complexity of the frames content, than the fact there are two of them.

What Visual Studio version are you using?

I did some multi-monitor work in VS6 in C, at an SDK level (i.e. not using MFC.)

If you don't find a solution, let me know and I will dig out some brute-force code I used to detect the number of monitors and position windows on the different monitors. It's not elegant but it works. As I said, it would be straight C stuff, not MFC - I never got into that complicated stuff!

Need to extract non-exported function of DLL

Hello,

I need to call some how non-exported functions of a DLL.All non exported functions don't have any table at all to which some looks up and find entries.

If some how we track the exact place where non exported function lies inside PE, copying or duplicating their entries in export table of that DLL of whom non exported functions I am interested in to call (until I need those non exported functions) and releasing those after done..

Any suggestions or recommendations?

If they are not exported then I do not think there is any way you can find them. Exported functions are only 'visible' because the LIB processor puts information in the DLL to make them so. Non-exported functions do not have this extra information so there is no way you can find them.

C++ application with dll in C:\WINDOWS\system32 problem

Hi there,

I have given this application that includes a dll and ini file that has to be in system32 folder in Windows machine and another VB application that uses the dll and ini to display the activities of the application. there is also another application that is Linux based and runs on Ubuntu to have just one server I want to install and run the application on the Linux based server by using Vine virtual machine. My problem is that I am not sure how I can change the C++ application code to read the dll and ini files from another folder (i.e. C:\Application) rather than Windows32 folder. Here is what the application have in config class (of course the original programmer didn't provide any comments or documents and the application is more than 15000 lines of code):

.h:
#ifndef __CfgClass_H__
#define __CfgClass_H__

#include <windows.h>
#include <windowsx>
#include "stdafx.h"

.cpp:

memset( CfgFilePath, '\0', MAX_PATH );
if( GetSystemDirectory( tmpFile, MAX_PATH )== 0 )
{
return;
}
wsprintf( CfgFilePath, "%s\\Application.ini", tmpFile );

Any help will be appreciated.

Regards,

Chan

Take this code:

wsprintf( CfgFilePath, "%s\\Application.ini", tmpFile );

and change it to:

wsprintf( CfgFilePath, "%s\\Application.ini", "<code>C:\\NewPath</code>");

I'm trying to the the SetElementProperty with the CDHtmlDialog, but can't figure out how to get the DISPID of the property to set. Can anyone point me in the right direction?

CDHtmlDialog seems pretty impressive, but I can't find a lot of coding examples using it.

Want to paste a file programatically (using C++) that's available in the clipboard

Hi All.

I can copy a text and then can programatically paste the same on top of any text editor.

Now, what I want to do is...
If I have a file in the clipboard (Ctrl+C) and then want to paste the same onto any open folder, then How can I do that?

I tried to send Ctrl+V to the window but I am unable to get the result.

Can someone please provide me some pointers, so that move ahead?

Please let me know, in case any clarification required.

Thanks
PanB

With open folder you mean explorer's windows? And since you tried to send Ctrl+V to the window i assume you know its handle. Try using Spy++ to see what command/message the window gets if the user selects "Paste" from the window's edit menu and then try sending the same to the window yourself, maybe it will get you what you want, maybe not, but it is worth a try.

Hi,

I have an application which is in pure c, I want to communicate through my MFC application. I looked the code of that application, some message are there like SDL_MOUSEBUTTONDOWN, SDL_MOUSEBUTTONUP. What it means?

And if I send message from my application to that application how can I achieve that.

When communicating with another application, you should first register a window message (see RegisterWindowMessage) and then use PostMessage (don't use SendMessage).

These are Windows messages which are sent in response to user actions. There are many messages all with unique values which tell the application what function is being requested. See the MSDN documentation for full details of the ones that you are interested in.

Your question is not very clear, perhaps you could try to reword it. You can send messages between applications by the SendMessage() or PostMessage() functions, but the full answer depends on what you are trying to achieve.

If you want the other application to process the message and return a result (an LRESULT) to you, then use SendMessage.

Otherwise, use PostMessage as already stated.
