ReceiveThread is a global function not a class member. AddListItem is a member function. You have to call a member function either in another member function or qualify the call using a . or a ->.

You need an object of your class type to call a non-static member function of that type.
You could pass an object (pointer) into your thread proc via the lParam:
DWORD WINAPI ReceiveThread(LPVOID lParam)
{
MyClass *pMyClass = (MyClass *)lParam;
//some processing here
pMyClass->AddListItem(...);
}
Pass the MyClass pointer as the LPVOID lpParameter in the CreateThread() call.

ok ill try that in a bit. but would it also be possible of passing the pointer of the function?

Yes, but only if it's a static method, or a regular function.

i have tried doing a static method however, since inside the function i am doing access to a non-static CListCtrl in which ill need to add items to it generates the error that it cant recognize the CListCtrl of the list in the dialog box.

Thanks Mark, I have already solved the problem using your way by passing the pointer to the class.

In icon view... is there a way to set the spacing between the top border and the top items? I'm using set position, but when I scroll down and then up again, the top icons are reassigned to a distance of about 2 pixels from the border.
This is how it looks:
-----------------------
| TTTT | 1 or 2 pixels (default)
| |
| |
| |
This is what i want:
-----------------------
| | 20 pixels
| TTTT |

Have you played around with the LVS_ALIGNxxx styles?

You mean LVS_ALIGNTOP and LVS_ALIGNLEFT? There's nothing I can play with there...

Yes, and LVS_ALIGNRIGHT and LVS_ALIGNBOTTOM.

Hi,
I wonder if unsigned 64bit integer is valid on a vc++ 6.0 compiler. In my application I have to use uint64 data type and whenever I try to use the command that is assigned to this, it fails. These are the two syntaxes that I have to use to define the buffers and the second one is for 64bit unsigned integer buffer on a system having a 64bit compiler and the first one is for systems with non-64bit compiler. If I have to use the first one, how can I define the low/high offsets and low/high transferlen.
Suppose I want to start the buffer with zero offset and buffer length of 1024x1024bytes.
//*************************************************************************
uint32 _stdcall spcm_dwDefTransfer_i64m(// Defines the transer buffer by using 2 x 32 bit unsigned integer values for each 64 bit value
drv_handle hDevice, // handle to an already opened device
uint32 dwBufType, // type of the buffer to define
uint32 dwDirection, // the transfer direction as defined above
uint32 dwNotifySize, // amount of bytes after which i want do receive
void* pvDataBuffer, // pointer to the data buffer
uint32 dwBrdOffsH, // high part of offset in board memory
uint32 dwBrdOffsL, // low part of offset in board memory
uint32 dwTransferLenH, // high part of transfer buffer length
uint32 dwTransferLenL); // low part of transfer buffer length
//*************************************************************************
uint32 _stdcall spcm_dwDefTransfer_i64 (// Defines the transer buffer by using 64 bit unsigned integer values
drv_handle hDevice, // handle to an already opened device
uint32 dwBufType, // type of the buffer to define as listed above
uint32 dwDirection, // the transfer direction as defined above
uint32 dwNotifySize, // amount of bytes after which i want do receive
void* pvDataBuffer, // pointer to the data buffer
uint64 qwBrdOffs, // offset for transfer in board memory
uint64 qwTransferLen); // buffer length
thanks,
-Pavan.

Did you try using the LARGE_INTEGER struct?
|
|
|
|
|
Sorry, didn't get you, I know there is LARGE_INTEGER data type, but where do you want me to use it?? This command is specific to the board driver that I am using.
thanks,
-Pavan

Something like this?
uint32 _stdcall spcm_dwDefTransfer_i64 (
drv_handle hDevice,
uint32 dwBufType,
uint32 dwDirection,
uint32 dwNotifySize,
void* pvDataBuffer,
union
{
uint64 qwBrdOffs;
struct
{
uint32 dwBrdOffsL;
uint32 dwBrdOffsH;
};
};
union
{
uint64 qwTransferLen;
struct
{
uint32 dwTransferLenL;
uint32 dwTransferLenH;
};
};
*EDIT* Fixed some typing :)

I have no idea how their developers (strategic-test) have developed these two syntaxes. Maybe same as how you defined, but I am not sure. I have asked their technical support to rephrase my i64 command into i64m command.
BTW how can we define the low and high addresses or lengths for a 64bit integer while accesses it in 32bit fashion??

With the structure I showed as an example you can access them either way - through the dw or the qw members.
The struct will work for both 32 and 64 bit but that doesn't mean that's what the driver vendor
does.

Why not use
typedef unsigned __int64 uint64;
typedef __int64 int64;
Which gives you easy to use 64 bit types just like unsigned/signed ints of other sizes, and then use unions as shown above to deal with the component parts?

Hi i would like to ask:
m_Btn (variable for a Button graphic)
how i will say if m_Btn.EnableWindow(TRUE) then return 0
if ( m_Btn.EnableWindow() == TRUE)
{
return 0;
}
?
|
|
|
|
|
<code>
if (m_Btn.IsWindowEnabled())
return 0;
|
|
|
|
|
and how if i want to say is Disable ? :P
(as i see m_Btn.IsWindowDisabled()) doesnt work
|
|
|
|
|
bool disabled = !m_Btn.IsWindowEnabled();
