You should wrap the LoadString WINAPI [^].

Hi!
I've one string array.It's declared as follows:

irr::core::array<irr::core::stringc> result;

Here is my Structure:

struct playerData
{
int   id,matches,innings,notouts,runs,highest,hundred,fifty,catches,strikerate,balls,runs_given,wickets,fivewkt;
char bestbowling[32];
};

I've to Copy the Array elements to Structure elements. How to do this?

You will need to assign each member individually (I guess you want to store each string in the id, matches, innings, ... mebers). Furthermore, you have to convert your different string to integer.

I think you are underestimating the power of your brain. You will learn more if you figure out things like that for yourself.

struct
{
    int a;
} s;
int arr[10];

s.a = arr[0];

Have a look at ADO[^] API. There are some useful code snippets.

Also, read about connection strings[^].

ReadFile function retuening zero for HID Device

8-Jul-10 0:33

if your's application is MFC based application, CDatabase class is there for manipulate database. If you wanna manipulate your database, you should make following steps..

1. Build ODBC connection string for SQL server for this refer to connectionstring.com
2. Create object for CDatabase
3. Using CDatabase::Open() function get connection to your database
4. Using CDatabase::ExecteSQL() run your insert query..
5. Finally close the connection CDatabase::Close()..

Hi all,

I am trying to communicate with HID Devices, but my problem is my ReadFile function always return zero.
I have written the code below

ReadHandle=CreateFile 
		(detailData->DevicePath, 
		GENERIC_READ, 
		FILE_SHARE_READ|FILE_SHARE_WRITE,
		(LPSECURITY_ATTRIBUTES)NULL, 
		OPEN_EXISTING, 
		FILE_FLAG_OVERLAPPED, 
		NULL);
Result = ReadFile 
			(ReadHandle, 
			InputReport, 
			Capabilities.InputReportByteLength, 
			&NumberOfBytesRead,
			(LPOVERLAPPED) &HIDOverlapped);

Before CreateFile i have used all the necessary api's to get the DevicePath value like SetupDiGetDeviceInterfaceDetail

Now, i am not getting that where is the problem.

Thanks in advance

From the documentation[^]:

If the function fails, or is completing asynchronously, the return value is zero (FALSE). To get extended error information, call the GetLastError function.

Note The GetLastError code ERROR_IO_PENDING is not a failure; it designates the read operation is pending completion asynchronously. For more information, see Remarks.

You are creating your ReadHandle with FILE_FLAG_OVERLAPPED, if you check GetLastError() after ReadFile, do you maybe get ERROR_IO_PENDING?

Hi,
I have to find the status for a particular file which is currently copying some where or not? If anybody know any DOS commands or have any idea regarding this, please let me know.

Thanks in advance

Hi all,

Im having

char *data = new char[256];

if i use cstring like,

std::string logFolder;
CString temp1;
temp1.Format(L"%s",data);
USES_CONVERSION;
logFolder = T2A(temp1);

I am able to get the correct path from data.

If i use like,

std::string temp;
temp = (boost::format("%s") % data).str();
logFolder = temp;

Anyone knows how to format the char array?Is parsing needed?Pls help me.
