windows doesnt provide any API for this?

Yes, but I don't know if the Delta Compression API [^] fits your needs. Have also a look at RtlCompressBuffer [^], RtlDecompressBuffer [^] functions.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Why such a restriction ? There are some great free tools which do exactly what you want. Why do you want to rewrite it yourself ?

Because the professor said he couldn't most probably.

Hi,
I have an application in which i am using a video for replay. Now when i use the print screen button i have to auto save this frame into a folder with some default name. Please give me some leads.

How do you play the video? If you are using DirectShow then you can add a samplegrabber filter to the filter graph to grab frames from the stream as bitmaps, you can then use GDI+ or somesuch to save the bitmaps as JPEG to wherever you wish. Am not sure if you are able to "overdefine" the Print-Screen button but i would try to define a hotkey for it in my application.

Hi,
how to convert from _bstr_t to std::string data type?
Thanx
|
|
|
|
|
Use _bstr_t's char* extraction operator:
_bstr_t bStr(L"Hello");
std::string str((char*)bStr);
Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p

Haven't used _bstr_t at all, but from the documentation I would say the extraction operator merely gives a pointer to the internal data buffer. That's most probably not what he needs. He should convert the UTF-16 encoded _bstr_t string to some multibyte encoding first to store it to std::string.

_bstr_t keeps an internal ASCII copy of the BSTR which is populated on demand. This copy is the internal data buffer that the char* extractor returns a pointer to. Therefore the answer I gave is what the OP needs and wants.

Interesting. Is it really ASCII, or whatever the system code page is ("ANSI")?

No idea - didn't look quite that far into the source (comutil.h in your VS distribution, if you want to look).

hi friend,
i have vb dll..in the vb dll one fuction f1;
Public Function f1(SendString As String) As String - this function taking as argument and return string...
how i will call in vc++;
CoInitialize(NULL);
hresult=CLSIDFromProgID(OLESTR("prjdll.clsdll"), &clsid);
_clsdll *t;
hresult=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_SERVER,__uuidof(_clsdll),(LPVOID *) &t);
CString str= "000001";
t->f1(str); // this is crasing....
please help any body.

You need to pass this as a BSTR (or possibly a BSTR encapsulated in a VARIANT). Open the VB DLL in the OLE/COM Object Viewer (use the File->View TypeLib... command) to see what parameter type the VB DLL is expecting to see for this call.

You cannot pass a CString's instance, you've to pass a BSTR.
Anyway, the

RASDIALPARAMS lpRasDialParams;<br />
ZeroMemory(&lpRasDialParams,sizeof(lpRasDialParams));<br />
wcscpy(lpRasDialParams.szEntryName, TEXT("我的连接"));<br />
lpRasDialParams.dwSize = sizeof(lpRasDialParams);<br />
BOOL lpBool = TRUE;<br />
DWORD dwReturn = 0;<br />
<br />
dwReturn = ::RasGetEntryDialParams(NULL, &lpRasDialParams, &lpBool);
dwRetrun value is 1168 ? what is this?

Try looking at the documentation for the function[^]. That points you at either the RAS specific errors or winerror.h. In winerror.h, you'll find this:
#define ERROR_NOT_FOUND 1168L
which I suspect means your entry name is unknown.
