If you created the control with CreateWindow[Ex]() then the API will return the handle.

If the control is on a dialog created from a dialog resource, the you can use GetDlgItem()
to get a handle to a dialog control given its ID.

If you can use Windows APIs, you could use GDI+[^]

The Boost library includes a very nice regular expression[^] library for use from C++. Documentation and examples are good. You can probably Google for a site that lists regular expressions for extracting information from HTML.

Host the document in MSHTML and use the anchors property of the IHTMLDocument2 interface.

Ohh yes.... sorry boss..
Here is the problem..
while reconnecting i m trying to execute a query to check whethere i got connected to DB or not??
That query returns me true which means i m connected to Database. Now i want to update some records from file to DB and at that time i m getting "OERROR_INVPARENT" error.
My question is how it can return me two different things at two different places.

Did u get my problem now??

I have made the Followind chages to my code but now it gives me followind Exceprion

Unhandled exception at 0x7c4f3ac3 in Dekstop-GUI.exe: 0xC0000005: Access violation writing location 0x00416856.

The Code is as follow.

	LPWSTR str = L"c:\\WINNT\\system32\\notepad.exe";<br />
	STARTUPINFO si;<br />

The following modifications may help you...

STARTUPINFO si;
PROCESS_INFORMATION pi;

ZeroMemory(&si,sizeof(si));
si.cb = sizeof(si);
si.dwFlags = STARTF_USESHOWWINDOW;
si.wShowWindow = SW_SHOWMAXIMIZED;
ZeroMemory(&pi,sizeof(pi));

Thnx,
But Error Still persist.
The prior code I just post to you is working well in other application. But it gives the Error in this Application only.

I am using MouseHook in my Programming. Can it generate any Probelem. Confused | :confused:

The second paramater expects a LPTSTR you are passing a LPCTSTR. CreateProcess() will try to modify the string in the second paramater.

TCHAR str[ MAX_PATH ];<br />
_tcscpy_s( str, MAX_PATH, _T("c:\\WINNT\\system32\\notepad.exe") );<br />
<br />
CreateProcess( NULL, str, ... )
