you can create a main function. Create an instance of your class in the main function. And then call the function with the object/pointer variable. Suspicious | :suss:

The same as you did in C++
In MFC applications however the main function is hidden.

Somethings seem HARD to do, until we know how to do them.

include the header file, where u want to create the object and functions. Then create objct and call function

In VC u can creatte diff. kind of projects using the wizards, so dont compare it with c++ main().

If u want to create dos type app, use Win32 Console App. wizrd.
u can create Windows app, using Win32 App wizrd..In this case u can see WinMain instead of main()

First learn about how to use VC++ and then start programming than this kind of Quick start....Slow and Study WIN(dows)the race Smile | :)

there are many thing and function are become obslete or replaced by better function in VC++ for Example Void main () is replaced by WinMan() in Win32 and CWinApp Wrap same in MFC!
so moral of story bought a VC++ book or look for online material to learn vc++...
have a look at Visual C++ 6 Unleashed (link Provided to me by VuniC)

Try this :

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

I hope this will help

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?

System-Wide WriteProcessMemory Hook

20-Jul-06 16:56

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

checksum

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.
