Try the below. If the socket is up, then it sets the bit for that socket in the flag variable.

flag = 0;

//...

if (CmdPkt->Param1 != 0)
{
  flag |= 1 << CmdPkt->Param2;
}

Simply write the data as a CSV file[^]. Excel can handle a CSV file.

CSV is a good way to go as the other poster suggested. If that doesn't do it you could resort to using the Excel OLE Automation interface.

You can also interact with Excel via ODBC. If you are using MFC, check out CDatabase and CRecordset. You'll need to create a DSN.

I believe that you can execute sql server code to create an xls file automatically. You also could use COM to create an excel file yourself.

Taken from another article I read
[^]

you can use
1> DTS Export/Import utility for that please go thru
http://support.microsoft.com/kb/319951[^]

2>exec master..xp_cmdshell but for that you need to enable from surface area configuration

3> BCP utility

4> you can use linked server for excel file to sql table.
INSERT INTO OPENROWSET('Microsoft.Jet.OLEDB.4.0',
'Excel 8.0;Database=\\servername\e$\inetpub\wwwroot\game\myexcelfile.xls;',
'SELECT * FROM [scores]') select * from LinkedServerName.DBname.tbl_Stats

5> SSIS package to transfer data from a table in a SQL Server 2005 database to a Microsoft Excel spreadsheet

GetDlgItemText

How can I get the length of the string GetDlgItemText would return, so I can create a big enough buffer? In the documentation it says GetDlgItemText will just truncate the string to fit the buffer, but I don't want that.

Use GetDlgItem to obtain the control's handle and then call GetWindowTextLength [^].

Printing Image

Hi In my application I am printing image.But the image which I have printed is very large and it is inverted.I tried to scaledown the image,but its not working.

My Code

CRect				rcPrintRect;

rcPrintRect.left		= nXMargin;		
rcPrintRect.right		= nPageWidth - 2 * nXMargin;
rcPrintRect.top			= nYMargin;		
rcPrintRect.bottom		= nPageHeight - 2 * nYMargin;

StretchDIBits(
		pDC->m_hDC,
		nXMargin + 5000, 
		rcPrintRect.top, 
		rcPrintRect.right - 7500, 
		rcPrintRect.bottom - 10500,
		0,
		0,
		bmpInfo.bmiHeader.biWidth,
		bmpInfo.bmiHeader.biHeight,
		buffUnComDropImg,
		&bmpInfo,
		DIB_RGB_COLORS,
		SRCCOPY
	     );

How to solve this issue?

Thanks in advance

Try debugging to see the actual values you pass into the function call.

Looking at your code I would say that depending on the size of rcPrintRect the Destination rectangle can have negative width and height. Try hardcoding it for starters and see if it helps.

The documentation for the function states:
If nSrcWidth and nDestWidth have different signs, the function creates a mirror image of the bitmap along the x-axis.
If nSrcHeight and nDestHeight have different signs, the function creates a mirror image of the bitmap along the y-axis.

In other words:

Change:

nXMargin + 5000,
rcPrintRect.top,
rcPrintRect.right - 7500,
rcPrintRect.bottom - 10500,

to:

nXMargin + 5000,
rcPrintRect.top,
100,
100,

Hope this helps Smile | :)

it is a matter of the sign (+/-) of the parameters, but take care to print not more than your output DC-size.

In some case also the bits of your image are bottom-top in memory!!! It is an IBM legacy Roll eyes | :rolleyes:

what do you really want to do?
I think you can use SetWidnowsLong to replace its original processing function then you can get the first chance to deal with key message.
And for SendMessage and PostMessage, you can just hook the two API function as normal.
