Ok I traced the error with your help Mark.
1. Totaly wrong parameters to SetWindowPost
2. It worked only with the GetWindowRect & ScreenToClient and not with GetClientRect ( I am curious why not???).
The combination of GetWindowRect / ScreenToClient should give the GetClientRect position, Am I wrong ?

Did you use of ScreenToClient on your code it converts screen coordinates to client coordinates.

Hi everyone,
Can anyone tell me, how to check whether entered text is RTL (for example: Arabic or Hebrew) or LTR(for example:English) text?
I am using Uniscribe in my application. If i don't use ETO_RTLREADING in ExtTextOut(), can i get correct output based on English or Arabic language entered?
Thank you,

hi everyone,
i'm working on a project which includes a DLL and a separate UserBroker (both written in ATL) object which is used for getting/setting registry keys and reading/writing to user directories. (the object will be used in Vista, so this is needed)
i want to read some binary data from registry and i have written this function properly:
STDMETHODIMP CUserBroker::QueryBinaryValue(BSTR bstrKeyName, BSTR bstrValueName, BYTE **pValue, ULONG *pnBytes)
the function body is simple. it just opens the registry key (using a CRegKey ) and uses its QueryBinaryValue method. the problem is somehow i just can't pass a BYTE array to the other process (which calls the CUserBroker 's method). the call to the method is this:
arr = (BYTE *)malloc(1 * sizeof(BYTE));
pub->QueryBinaryValue(ATL::CComBSTR(s_bstrToolBarRegistryKey), ATL::CComBSTR("hop"), &arr, &dwSize);
arr = (BYTE *)realloc(&arr[0], (dwSize) * sizeof(BYTE));
pub->QueryBinaryValue(ATL::CComBSTR(s_bstrToolBarRegistryKey), ATL::CComBSTR("hop"), &arr, &dwSize);
delete arr;
everything works fine until the first line of CUserBroker::QueryBinaryValue method, where the BYTE** pointer points to BadPtr (0x00000000) immediately.
the question: how can i pass a BYTE array (or any other array) among processes?

thanks, the article was really helpful. i used BSTR to pass the array safely among processes. i thought i needed some structure like BSTR for this, but couldn't imagine the solution would be BSTR itself
WM_COPYDATA is useful too, but since my UserBroker does not have a window, i can't send the message to anywhere else.
thanks again

how to get the VARIANT type URL as a CString from OnDocumentComplete in webbrowser2
void MyDialog::OnDocumentCompleteExplorer1(LPDISPATCH pDisp, VARIANT FAR* URL) <br />
{<br />
<br />

"URL" here contains the url that has been completed. but it is a variant type. i want to as a CString type so that i can check it. i tried casting but it doesnt work. does anyone knows how to do it?
- MFC style
- winxp
- vc6.0
thanks in advance!

you can use the V_BSTR macro to get it done. the macro returns a BSTR that you can use to obtain a CString . something like this may help/work:
BSTR bstrUrl = V_BSTR(URL);
CString cstrUrl(bstrUrl);

A variant type has many different subtypes, one of which is a BSTR. For example:
COleVariant vtURL(URL, VT_BSTRT);
CString strURL = V_BSTRT(&vtURL); Or:
CString strURL(V_BSTR(URL));

Hello all,
I was wondering if I can use the new CString class that came with VC++2005 but in VC++6...
If this is possible, how should it be done?
As always thank you in advance...

No, but you could possibly derive your own class from CString , and add methods to it that are similar to those in the VS2005 version.

CString.tokenize...
I wanted to use that and not a custom made tokenizer...
I'm sure that there are plenty of them here in CP, but well, I have an old app that deserve a little of maintenance... and I've got used to use that tokenizer...

You can use AfxExtractSubString() in VC6

Thank you, I'll give it a try...
