Could be a lot of things. What is in m_ storagePath ? Does the file exist? Do you have read and write access to it? Does some other process have it open and it's only shared for reading?

you can get the error string by using FormatMessage() . Just change the code to as shown below. This will display the error string corresponding to that of error code.
hFile = CreateFile( m_storagePath,<br />
GENERIC_READ|GENERIC_WRITE, <br />
FILE_SHARE_READ,<br />
NULL,<br />
OPEN_ALWAYS,<br />
FILE_ATTRIBUTE_NORMAL,<br />
0);<br />
<br />
<br />
if (hFile == INVALID_HANDLE_VALUE) <br />
{ <br />
LPVOID lpMsgBuf;<br />
FormatMessage( FORMAT_MESSAGE_ALLOCATE_BUFFER | <br />
FORMAT_MESSAGE_FROM_SYSTEM | <br />
FORMAT_MESSAGE_IGNORE_INSERTS,<br />
NULL,<br />
GetLastError(),<br />
MAKELANGID( LANG_NEUTRAL, SUBLANG_DEFAULT ), <br />
( LPTSTR ) &lpMsgBuf,<br />
0,<br />
NULL );<br />
<br />
cout << endl << (LPCTSTR)lpMsgBuf << endl;<br />
<br />
LocalFree( lpMsgBuf );<br />
}

How can we change the size of the splitter bar in a splitter window?

Derive a custom class from CSplitterWnd class. In the constructor of derived class change the value of m_cxSplitter and m_cySplitter. Simply doing this will slove your problem and use the derived class instance

I use these (where splitterwidth is the size of the splitter I want and borderwidth is the size
of the 3-D border around the views:
m_cxSplitter = m_cySplitter = splitterwidth + borderwidth * 2;
m_cxBorderShare = m_cyBorderShare = 0
m_cxSplitterGap = m_cySplitterGap = splitterwidth + borderwidth * 2;
m_cxBorder = m_cyBorder = borderwidth;
I also added customizable colors to all individual borders and the splitter which required a
CSplitterWnd::OnDrawSplitter() override.
I almost wrote an article for it (it all started in response to a CP question) but I noticed
hundreds of articles were already there LOL.

Hello ,
Can anyone help with the declaration of arrays on the .NET 2.0 platform ? I get an error "subscript requires array or pointer type . Codes listed below
public: System::Void convertStringToBinary(String ^myString)
{
binaryVal = "";
__wchar_t characterArray gcnew[];
characterArray = new __wchar_t gcnew[myString->Length];
myString->CopyTo(0, characterArray, 0, myString->Length);
for(unsigned long int i=0; i<characterarray->Length; i++)
{
binaryVal = String::Concat(binaryVal, characterArray[i]>=128 ? "1":"0");
characterArray[i] %= 128;
D

Maybe something like:
array<__wchar_t> ^characterArray = gcnew array<__wchar_t>(myString->Length);
And yes, this should be posted on the C++/CLI board

Hi,
I am using LogOnUser() API to check whether My application has similliar logon username and password same as my windows username and password. If i give a wrong user name and password it takes almost 15 secs to return. Is there a way i could make it faster?
BOOL bRes = LogonUser( m_strUser,
NULL /*domain*/,
m_strPassword,
LOGON32_LOGON_NETWORK /*dwLogonType*/,
LOGON32_PROVIDER_DEFAULT /*dwLogonProvider*/,
&hUserHandle);
It is because of passing NULL for the domain name, there are around 10 domains and that is the reason it takes so much of time i guess. Is there a way to get the current doamin pls suggest how to go about?

Use NetWkstaUserGetInfo(NULL, 1, ...) .

Ok, so what's the problem? Do you want to load it explicitly or implicitly?

You can if you want
Did you get any message if you want to use it you must use of LoadLibrary for load it and then use of GetProcAddress for returns the address of funtion on the dll and in the end use of FreeLibrary if its not your question Can you more explain,please
