Hi All
I want to develop a USB Small project which show all information about USB Device like USB Device name,drive name and file or folder name.Plz help me..
|
|
|
|
|
|

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

AfxMessageBox(szRootpath);
//* represent search all files and directories

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.
Preethi.

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.
