Hi,
I am trying to specify an exit code of a dialog-based MFC application. One way I have found is to directly set the m_msgCur.wParam of the CWinApp class.
For example
BOOL CImportArinApp::InitInstance()
{
m_msgCur.wParam = 2;
return FALSE;
}
Is there a better way to specify the exit code of a dialog-based MFC application?
Thanks,
Sravan

I don't know if this is the right thing to do but I tried OnDialog::OnCancel before and it worked.
Comments are welcome

Hi Sravan,
CWinApp::ExitInstance
virtual int ExitInstance( );
Return Value
The application's exit code; 0 indicates no errors, and values greater than 0 indicate an error. This value is used as the return value from WinMain.

Hi everybody. I have a problem. I have a file mapped in memory, and a pointer to section of that file, and i need to read n bytes from the file in memory begining in the pointer. If anybody can helpme i will be gratefull.

If the file's memory mapped, then you treat it exactly like memory - so 'reading n bytes' from the file is simply a memcpy(). If you want to emulate file-like behaviour, try something like (untested code!):
const char* gFileBase = address at the beginning of your memory mapped file;
size_t gFileSize = size of the file that was memory mapped;
size_t filePtr = 0;
int memfread(void* destination, size_t numBytes)
{
size_t bytesRemaining = gFileSize - filePtr;
if (numBytes > bytesRemaining)
numBytes = bytesRemaining;
memcpy(destination, gFileBase + filePtr, numBytes);
filePtr += numBytes;
return numBytes;
}
Something like that anyway - you can hopefully see how you might implement memfseek() and so forth.
Of course, ideally you'd reap the most benefits from a memory mapped file simpply by treating it pure memory. For example, if your file was an array of Foo structures:
Foo* fooArray = reinterpret_cast<Foo*>(gFileBase);

Create a class that has is initialized with a pointer to that section and it's size.
Every read request will increase the pointer by the amount of bytes read.
If that amount gets bigger than the section's size, the EOF is reached.
Don't try it, just do it!

Dear friends,
I want to call a function exposed by a DLL. For this purpose i am loading a DLL dynamically using LoadLibrary() and then calling GetProcAddress().
The name of the function i want to call is MSPeelerMain. I dont know about its parameters. Unfortunately the only example present in MSDN
is in VB where the function is declared as:
Function MSPeelerMain (ByVal sHtmlFile As String, ByVal sCmdOptions As String) As Integer
I want to call this function in C++ and as such i am declaring it as:
typedef int (*MYPROC)(LPTSTR, LPTSTR)
But when my program executes i am getting run time debug error:
The value of ESP was not properly saved across the function call.
This is usually a result of calling a function declared with one calling convention with a function pointer declared in other
calling convention
Can you tell me how to solve this problem ??

Does modifying the typedef to indicate stdcall calling convention help?
typedef int (__stdcall *MYPROC)(LPTSTR, LPTSTR)

since VB -String = VC-BSTR
so you can try .....
typedef int (WINAPI *MYPROC)(BSTR, BSTR)

Interprocess Communication is use to communicate between two or more process (based on method you are using). Now let if you Window Service have window it must have HWND associated with it... so using Simplest Interprocess mechanism i.e. Window Message you can Post your User Defined messages (WM_APP+ and WM_USER+) with some other program/process and instruct the service to work according to it...
This is just simple logic. Better you try this logic with two desktop-based application before applying directly to service.

Definitely, no.
Definitely, yes - if you can access information on the Kernel internal structures. But even if so, your app may not work on different Windows versions.
One always gets the deserved.
