On the project property's 'Configuration' tab, specify 'use MFC in a static library'. This will remove dependencies on the MFC dlls; you won't have to redistribute those with your .exe. Any third-party dlls you might use will still have to be distributed with the app. Place them in the same directory as the .exe when distributing.

If you want to get a little more professional, you can put together an installation package (.msi) that can create shortcuts to the user's Programs directory, creates any necessary registry entries, etc. VS05 supports this - it's pretty straightforward.

Hello

The best is to use a PDF Printer Driver.
it is a virtual printer that you install on your computer and you call when you want to print your document.

Somes are free .. and somes not.

dynamic_cast fails

Maxwell Chen9-Nov-09 22:13

There is an Edit control on the dialog. The ID is IDC_EDIT.

In CMyDialog::OnInitDialog(), I do this ...

CEdit* pEdit = dynamic_cast<CEdit*>(GetDlgItem(IDC_EDIT) /* = some valid address */);
if(!pEdit) {
  // Error;
}

The CWnd* returned from GetDlgItem failed to convert to a CEdit*. But isn't CEdit derived from CWnd? Confused | :confused:

Hi Maxwell,

Maxwell Chen wrote:

Yes, but GetDlgItem does not always return a CEdit pointer so the dynamic_cast runtime check fails. Have a look at the following document:

Inside MFC: Handle Maps and Temporary Objects[^]

Essentially... when GetDlgItem cannot find a permanent object in the MFC CHandleMap it will return a pointer to a CTempWnd object. So your code fails to dynamic_cast from CTempWnd to CEdit.

As an experiment you should add a CEdit member variable to your class for IDC_EDIT. This will cause the CHandleMap to have a permanent handle. Now your code will magically work. Smile | :)

Hi,

How to read a DWord Value from Registry... Iam trying with the following code but iam getting Garbage Values... can any body help me out....

void ReadValue()
{
HKEY hKey = 0;
DWORD dw,dwValType;
LPBYTE pbData;

if(RegOpenKeyEx(HKEY_CURRENT_USER, "Software\\Praveen", 0, KEY_READ, &hKey) == ERROR_SUCCESS)
{

if(RegQueryValueEx (hKey,"DWORDSample", NULL, NULL, NULL, &dw)==ERROR_SUCCESS)
{

pbData = (LPBYTE)malloc(dw);

RegQueryValueEx (hKey, "StringSample", NULL, &dwValType, pbData , &dw);

cout<<"\n\nDecimal Value"<<(DWORD)pbData<<"\n\n";

RegCloseKey(hKey);
}

}

}

Thanks in Advance......

You get the size information for "DWORDSample" and then try to retrieve the value of "StringSample"! What is the correct name of your value variable?

First of all, your variable "dw" is not initialized when you're calling RegQueryValueEx. Also, you set the address for the data buffer to NULL.

I think that is the correct call to obtain the size of the variable before getting its value.

Try it this way:

 HKEY hKey = 0;
 DWORD dw;
 DWORD dwData;

 if(RegOpenKeyEx(HKEY_CURRENT_USER, "Software\\Praveen", 0, KEY_READ, &hKey) == ERROR_SUCCESS)
 {
  if(RegQueryValueEx (hKey, "DWORDSample", NULL, NULL, NULL, &dw)==ERROR_SUCCESS)
  {
    RegQueryValueEx (hKey, "StringSample", NULL, NULL, (LPBYTE)&dwData , &dw);
    RegCloseKey(hKey);
  }
 }
}

Hi all,

I am calling some methods from the Web service which i have added to my solution.
For Example please refer below code.

below code is perfectly running fine on XP,Vista but i have tested it on Windows 2000 prof.

line 1: CoInitialize(NULL);    
line 2: xyzService::CxyzService test;
line 3: CComBSTR result;
line 4: test.Methodname(CComBSTR(L"0001"),CComBSTR   (L"0001"),&result);
line 5: CoUninitialize();

if i run this code in Win 2000 it gives below error,
"the procedure entry point Getaddrinfo could not be located in the dynamic link library WS2_32.dll"
if i comment line no. 4 from above code,it runs properly.
This error is arriving due to call of any method in webservice.
Please help me to find some solution.

Thanks in advance

Hi Rahul,

Your webservice may be calling the Unicode version of GetAddrInfo. And if you have a look at the MSDN for the GetAddrInfoW Function[^] it states that the minimum operating system is Windows XP with SP2.

Windows 2000 should support the ANSI version: getaddrinfo function[^]

Is it possible to overcome this problem through our client Application(My MFC application)?

Hi Rahul,

You can use the ANSI version by explicitly calling the GetAddrInfoA function. Make sure that you pass ANSI strings to the function.

Hi Randor,
thanks for reply..

I have done code like below
but still i have same problem. Frown | :(

Please let me know am i coding in the right direction, because this thing is new for me..

WSADATA wsaData;
    int iResult; 
    DWORD dwRetval;

    iResult = WSAStartup(MAKEWORD(2, 2), &amp;wsaData);
    if (iResult != 0) {
        printf("WSAStartup failed: %d\n", iResult);
        return 1;
    }

    //--------------------------------

    hints.ai_family = AF_UNSPEC;
    hints.ai_socktype = SOCK_STREAM;
    hints.ai_protocol = IPPROTO_TCP;

//--------------------------------"
// Call getaddrinfo(). If the call succeeds,
// the result variable will hold a linked list
// of addrinfo structures containing response
// information
	

    dwRetval = getaddrinfo("xx.x.xxx.xxx", "80", &hints, &result);
    if ( dwRetval != 0 ) {
        printf("getaddrinfo failed with error: %d\n", dwRetval);
        WSACleanup();
        return 1;
    }
