Try this :

CString consoleData=ExecuteExternalFile("cmd.exe","Notepad");
//AfxMessageBox(consoleData);
// consoleData has the MS-DOS text

I hope this will help
!OOPS----- See here for ExecuteExternalFile function

ok..Another way..Take project->Setting->C++ tab

in the category combo take "Precompiled Headers"

Now check the Radio button "Not using precompiled headers".

Then rebuild the preoject.

Are you using VS2003 or vs2005??
#include <stdafx.h> should be in the first line of all include statements.
Just check this.

Doing a Rebuild All can sometimes fix weird build errors, give that a shot. That will also rebuild the source browser files.

How to get USB device address?

for (index=0; SetupDiEnumDeviceInterfaces(deviceInfo, 0, (LPGUID)&GUID_CLASS_USB, index, &DeviceInterfaceData); index++) {
memset(tempstr, 0, 1024);
deviceDetailData = (PSP_DEVICE_INTERFACE_DETAIL_DATA)tempstr;
deviceDetailData->cbSize = sizeof(SP_DEVICE_INTERFACE_DETAIL_DATA);
SetupDiGetDeviceInterfaceDetail(deviceInfo, &DeviceInterfaceData, deviceDetailData, 1024, &requiredLength, NULL);

hUSBHandle = CreateFile(deviceDetailData->DevicePath, GENERIC_READ | GENERIC_WRITE, 0, NULL, OPEN_EXISTING, FILE_ATTRIBUTE_NORMAL, NULL);
CloseHandle(hUSBHandle);
}

I would like enumerate all usb devices and get their device address.
How could I do?

Thanks and regards

System-Wide WriteProcessMemory Hook

Hi guys,

I posted before but looks like that post is long gone. I also didnt describe the problem very well so here i will go at another attempt.

I am using DLL Injection to do a system-wide WriteProcessMemory Hook using Microsoft Detours. My hook works, because I get the desired change in the function but there is one problem that I do not understand why it is occuring. Everytime I initiate the hook, explorer.exe seems to crash. That is the only program that crashes and I do not know why. Would anyone know why it would crash?

I want to try a different method. Specifically on hooking the export. Would anyone know how I would do a hook on the WriteProcessMemory Export in kernel32?

Any help to my two questions would be appreciated. I'll post some code if you need it.

Thanks,

Robbie

hey all,
I do a checksum logic on both the serial device and the Pc end to see if the correct packet is received.

I do :

<br />
	for (i = 0 ; i < (nMaxLenPkt2Tx - 1); i++)<br />
					  {	cChkSum_2pc ^= txbuffer[i];}<br />
<br />
  						txbuffer[i] = cChkSum_2pc;

and then send the packet from the serial device to PC.

and on Pc's end, I do this after receiving the packet before copying it to a local buffer.

char cChkSum = 0;<br />
		<code>for (i = 0 ; i < (PKTINFO_LEN_MPU_2PC - 1); i++)<br />
			<br />
				cChkSum ^= m_cBufPktInfo_mpu_2pc[i];

and compare this checksum count with teh received checksu count in the packet to determine if it is a correct packet or not. ie.,

if (cChkSum != m_cBufPktInfo_mpu_2pc[PKTINFO_LEN_MPU_2PC - 1])<br />
			{<br />
				TRACE("Received a bad packet!\n");<br />
}<br />

But I get badpacket everytime . Waht could be wrong? the datatypes and the length of the packet sent and received are the same. I have checked that.

Any ideas/help?
Thanks in advance.

Big Int Class

Ok so here is the situation,

I had an assignment due in my class(Don't Worry it is over now, however I had to turn it in incomplete) I want to finish it up for the learning experience my class is a 100 level class at my college and it is programming in C++.

Here is the link: Assignment BIGINT

Now I have finished some of it and commented most of it so hopefully it will be easy to understand where I am.

Class Definition:Class Definition
Class Inplementation:Implemenation

The main point of this assigment was operator overloading and I need to get +, -, *, / ++, --, +=, -=, ==, !, >, < overloaded.

Now I know that this is a large amount of work, however I was hoping we could work at this one step at a time and I would appreciate this an extreme amount. Thanks Alot Guys

Ok Well to be specific I have been working on it the last two days, I really need help with

* & / I am sure that if I get these I will have no problem with the rest of it.

ALSO I have updated the class and class implementation with what I finished last night. Added material includes:

Constructors all complete.

+=(Although it uses + operator)
-=(Also uses - operater)

==, !=, <, >

and negative -(unary -)
