OK. So you are using SetupAPI to query USB information. I believe, once you get hold of the device you can use the regular CreateFile, ReadFile, FindFirstFile etc API

Well, s value is just 0x003c2750.
Possibly you need *s value.

i think everyone is missing the point stated in the qns.
the qns states that
char* s = "0x12345567"
which is a null terminated string
and the poster wants to get the value of the memory 'pointed' by the string (not the pair of quotes around the address.
Thus *s will not work.
what you need to do is to parse the char* into a int or long (depending on whether it's 32bit or 64bit)
I believe this is what you wanted (thou it's almost 5 mths late )
char* s = "0x0012ec08";
char* stopString;
long address = strtol(s,&stopString,16);
void* pPointer = (void*)address;
depending on what is the value you want, you will then type cast pPointer to whatever type, for example
byte* pByte = (byte*)pPointer;

Hi,
I need to get the state of Radio Button ,According to the Radio button state i need to change the text on one push button.
Plz Advice.

Using raw Win32 use the BM_GETCHECK[^] message or the Button_GetCheck[^] macro. If using MFC you can use the CButton::GetCheck function.

Events and delegates are your friends here. This will let you change your button text anytime the selected radio button changes. Check google for more details. There should be plenty of tutorials out there. You may even find some code snippets in the articles here that do something similar.

Delegates? Are you thinking of C#?

I was thinking Visual C++. I'll admit, I haven't done any MFC programming, my work is all in C++ .NET, where we do have delegates. I guess I should probably do a bit of reading up on MFC before posting anything in this forum again. My apologies if my previous post is misleading at all.

Hi all,
I am working in vc6.0 using MFC.
I have a peculiar problem with Edit box display.
I have some parameters to display in edit box like,
Flash type : 0
Flash Address : 0x00
etc.
I need to align ':'character so that':' appears on the same column
So I am stuffing the Flash Type with spaces.
Eventhough I change the location of ':' to be same,
The edit box is displaying like,
Flash type : 0
Flash Address : 0x00
The alignment is not proper.But If I send the buffer to hyperterminal the alignment is proper.
Please clarify how can I align ':'in edit box.
Regards,
Sunil Kumar

Change the font of the edit control to Courier. As a hint to create a font use CreatePointFont( 120, _T( "Courier" ), NULL );

Make sure that the "Flash type:" and "Flash Address:" labels (i.e., static controls) are the same width and are right-justified.
