If it's a string literal, yes.

Someone could fairly easily view all the string literals in your .exe file. Alternatively they could replace the EXE that you are launching via CreateProcess and they could display the command line from their EXE.
|
|
|
|
|
The Process Explorer[^] utility can show the command line that any process (to which you have access) was launched with. I think it does this by using the ReadProcessMemory API. By default, processes have ACLs (security settings) set so that only the creator of the process can use this API, but this behaviour can be overridden with use of the Debug privilege, which Administrators have by default - and as we all know, most people log in to Windows as a member of the Administrators group.

sadly I'm talking not about advanced compiling options but fonts, background colours and the like. I realise that this is something that probably comes over time as a personal preference, but wondered if anyone had any good links on a good start. I used to have one set up when I worked in programming with black background code windows and certain keywords all coloured in to make it easier to spot types and stuff.
I'm sure someone has good info, links or advice. gratefully received
cheers

I use the default with a few minor changes. Red/white for numbers; Blue/white for keywords; Green/white for comments; White/blue for string literals. Black/white for all else.

Hi,
i needed to change the position and rotate a GIF image in given angles as per user inputs in a MFC application .
So I started to use Image object in GDI+.My intention was to make a Image object and manupulate its position and orientation.(As given in msdn page titled Drawing, Positioning, and Cloning Images - refer the link below)
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/gdicpp/GDIPlus/AboutGDIPlus/IntroductiontoGDIPlus/OverviewofGDIPlus.asp[^]
I tried to insert a image to my main frame using "Image" in GDI+. But a runtime error (unhandled exception) is occuring when im going to run the program.The details are as follows.
I have included "gdiplus.h" in StdAfx.h. There were no issues on that.But the problem started when i tried to insert a image using the guidelines given in above msdn link(.Drawing, Positioning, and Cloning Images - GDI+)
As per that method I used the following code:
CPaintDC dc(this);<br />
Graphics myGraphics(dc.m_hDC);<br />
<br />
Image myImage(L"robot.gif");
myGraphics.DrawImage(&myImage, 20, 10);
The program Built & compiled successfully in VC++ 6.0.But didn't run.It gaves a error.
When I insert that code to a .NET project the error message says that ;"Unhandled exception at 0x7c9105f8 in tttdk.exe: 0xC0000005: Access violation reading location 0x00000010."
When I break it , it shows the location of the error in the following cpp file.
D:\VS\VC\atlmfc\src\atl\atls\allocate.cpp
<small>..<br />
<br />
...<br />
<br />
CAtlTraceCategory *CAtlAllocator::GetCategory(int iCategory) const<br />
<br />
{<br />
<br />
if(iCategory == m_pProcess->CategoryCount())<br />
<br />
return NULL;<br />
<br />
<br />
<br />
ATLASSERT((iCategory < m_pProcess->CategoryCount()) || (iCategory == -1));<br />
<br />
CAtlTraceCategory *pCategory = NULL;<br />
<br />
if(iCategory >= 0)<br />
<br />
{<br />
<br />
BYTE *pb = reinterpret_cast(m_pProcess) + m_pProcess->MaxSize();
<br />
pCategory = reinterpret_cast(pb) - iCategory - 1;<br />
<br />
}<br />
<br />
return pCategory;<br />
<br />
}<br />
<br />
..............</small>
Please help me regarding the above matter ASAP.or else tell me way to Insert a GIF image to a MFC frame and to change its position and rotate by given angles time to time.

Just a shot-in-the-dark:
Based on your code line alone:
BYTE *pb = reinterpret_cast<???>(m_pProcess) + m_pProcess->MaxSize();
Is MaxSize by any chance the fourth virtual method in m_pProcess? Do you have a memset(m_pProcess, 0, sizeof(...)) or equivalent somewhere? If so I think you are zeroing out the vtable. You can't use memset on a class with virtual methods.
Based on the code above that is the only thing I can think of that would make it crash.

Thank u very much for attending this matter.Actually I dont know what is error that comes when im runing the application.
There appears a window asking whether to send the error report to Microsoft. I tried to see the technical information in that report.But can't understand.It states about an exception. The appilication error states that the memory could not read at a location(memory address was given)
When I debug it following appeared..

Right - that is to be expected! That information says exactly the same thing as your OP.
> The thread 0x9C8 has exited with code -1073741819 (0xC0000005).
0xC0000005 is the code for an access violation. I refer you to my previous post - what is m_pProcess? One of your classes? Or a library class? If so, which library and what's its type? CProcess? Check to make sure you aren't memset-ing m_pProcess to zero anywhere.

look at the Shell_NotifyIcon() API. You can add an icon, then later modify it using this API.

Hi all,
I have flicked through the examples here on CP but not really found what I want. I'm looking for code examples/thoughts/ideas on the following:
1. Self modifying code
2. Self detecting if exe has been copied
3. PC serial numbers (anything unique to a single computer)
Maybe it is impossible but I am trying to develop 'full version' exe that will revert back to a 'demo version' if copied to another machine.

Not possible as far as I know.

Even if you were to take the HDD's volume/serial number, what would happen if my HDD crashed and I got everything restored to a new HDD? The software would detect that something is different and stop working. I'm not sure how to effectively handle this.

You can do this in Assembly, which is more fun than C++ anyway.
Good luck with it

the only thing i can think of is using resources, reate some kind of CRC em embedd it in a resource (ex: image)
However this is easy to crack

Network card adapter number (MAC address)?
People could allways change the card from one PC to another, but the software only works wher the card is.

Thanks for all the ideas everybody. This project is just something I would like to try in the near future. I guess I have a bit more reading to do before I make a start.

Hi all,
I have explored the MSMQEvent in VC++. But i can't get a Clear Picture, which is used to Capture the Arrival of any Message from the End User to invoke the MSMQ Service.
I want an example on MSMQEvent, Not all other stuff on MSMQ. please help me out.

Have you seen this example
