How can a dialog be centred? Please explain it with example and appropriate function call and also how can a combo box and radio button be added to the toolbar and what is the function for this.

ugly casting warning DWORD to PVOID

Hello im trying to print memory dump to console output stream.

<br />
for (UINT z = 0; z < 32; z++)<br />
printf("0x%0.2x ", (BYTE)(((PDWORD)((PVOID)exp->ContextRecord->Eip))[z]));<br />

Warning I get:

<br />
warning C4312: 'type cast' : conversion from 'DWORD' to 'PVOID' of greater size

exp->ContextRecord->Eip is DWORD type. Any ideas how to cast this wihout CL warning?

Thanks in advance!

For one, you aren't taking the address of exp->ContextRecord->Eip.

Beyond that, your code makes no sense. On the one hand, it looks like you are attempting to pull one bit at a time from the value, yet it also looks like you are trying to display each byte that makes up the DWORD value.

I'm thinking you want something more like this:

DWORD val = exp->ContextRecord->Eip;

for (int z = 0; z < 4; z++)
{
    printf("0x%0.2x ", (BYTE)(val & 0xff));
    val >>= 8;
}

Or just unroll the loop for a small optimization:

DWORD val = exp->ContextRecord->Eip;
printf("0x%0.2x ", (BYTE)(val & 0xff));
val >>= 8;
printf("0x%0.2x ", (BYTE)(val & 0xff));
val >>= 8;
printf("0x%0.2x ", (BYTE)(val & 0xff));
val >>= 8;
printf("0x%0.2x ", (BYTE)(val & 0xff));

Anyone who thinks he has a better idea of what's good for people than people do is a swine.

To output a pointer value using the printf family of functions, use %p in the format string. To print a DWORD, use %lx. To get a zero-filled DWORD, use %08lx.

I can only guess at what you were trying to do. Were you trying to dump the code at the location of an exception?

The warning itself is telling you that, if you were to recompile this code with one of the 64-bit compilers, that this line would potentially behave differently. The compiler doesn't really know that the CONTEXT type would be different on a 64-bit processor anyway and that this line therefore wouldn't compile. If you want to turn off the warning, use #pragma warning( disable: 4312 ), or disable the /Wp64 compiler switch.

I recently saw a recommendation from someone at Microsoft that you should now just use the 64-bit compiler to check compatibility and not rely on /Wp64 anyway.

I have a very simple question.I speficy the source files for a program in makefile as follows

PROGRAM = sq.exe
all: $(PROGRAM)

########### list of C++ source files
CPPSRCS = \
main.cpp

.......
........
########### build a list of all .obj files
OBJS = $(CPPSRCS:.cpp=.obj) $(CSRCS:.c=.obj)

########### how to link .obj files to create an executable
$(PROGRAM): $(OBJS)
$(link32) -out:$@ $(OBJS) $(LIBS) $(linkflags)

Now in case i have a large number of source files - how can i specify at directory level - viz. all cpp files under directory 'source'?

I want to be able to automatically install some driver files for use by my application. I have looked high and low and cant find any API documentation to help me out. Does anyone know of a way?

You can use ShellExecute() or CreateProcess() with devmgmt.msc.

Sorry to be such a pain. Can you eleborate a little? I have used both these functions in the past but how on earth would I use them to prompt the device manager to install some drivers from a particular location?

David Crow14-Aug-06 5:48

Re: Launching Device Manager or manipulating device manager from C++

14-Aug-06 5:48

My reply was simply in response to the "Launching Device Manager" subject. It obviously could not be used to install devices/drivers.

Do those driver files have a setup/install program?

No.
They are custom drivers that have been written for our specific hardware. I have looked high and low for information on it. Im sure its possible but MSDN doesn't have all that much information.
