Who is imposing that restriction? A silly restriction, if you don't mind my sincerity. Is this a real world program, or is it some sort of test? What's the reason for not wanting to derive the CPropertyPage? Please explain that.

I just wonder how to get the CBN_SELCHANGE message passed to the view.

The easiest and logical way to do it is to derive the page, receive the notification there and pass it to wherever you want or need. It can also be done in other not so direct ways. For example, you might subclass[^] a window, either the combobox itself or its parent page, but perhaps that's against the rules too?

You are right.

It is.

Subclassing the combobox? Oh no. Well, I see I won't get it done within the view. I think I should rather occupy with the silly restriction than trying to find a solution. D'Oh! | :doh:

How to get mouse events in console application

Bin2Hex15-Jul-05 3:34

Bin2Hex

15-Jul-05 3:34

I'm using VC6 to build a console app. In it I need to know when the user clicked a mouse button (don't matter where, nor what button was pressed). I followed the MSDN indications and did the following to enable my app to receive mouse input notifications:

HANDLE hStdIn = GetStdHandle(STD_INPUT_HANDLE);

SetConsoleMode(hStdIn, ENABLE_MOUSE_INPUT)

Then I check for mouse input this way:

BOOL bOk;
INPUT_RECORD impRec;
DWORD dwReaded;

bOk = ReadConsoleInput(hStdIn, &impRec, 1, &dwReaded);

if (!bOk || dwReaded == 0)
  // get out

if (impRec.EventType == MOUSE_EVENT_RECORD)
  ProcessMouse(impRec.Event.MouseEvent);

The problem is that no mouse notification arrives. In the real code I check also for keyboard events and they are notified ok, but no mouse events.

Can anyone help me on this one?

TIA

Hello,

Try the following:

CString sEnteredSerialNumber = "";
// get the serial number from the GUI

CString sYourHiddenSerial = "";

// get your serial number from somewhere
if( sYourHiddenSerial.CompareNoCase(sEnteredSerialNumber) != 0 )
{
    // oops wrong serial
    return;
}

// valid serial number
return;

Hi ,
Thanks for the immediate response . I need to enter 15 digits and it shud check whether the 15 digits are entereed i.e if i try to enter 13 digits it shudn't allow me proceed further . hope you get what i mean . This is actually an install shield which i 'm creating in which i have a user registration dialog in which i will have cust enter serial number so i need a code to check that whether he or she has entered correctly 15 digits

for ex :
// Serial Validation DLL.cpp : Defines the entry point for the DLL application.
//

#include "stdafx.h"

#define PIDKEY_LENGTH 100
#define DIGIT(a) ((a) - '0')

BOOL APIENTRY DllMain( HANDLE hModule,
DWORD ul_reason_for_call,
LPVOID lpReserved)
{
return TRUE;
}

UINT __stdcall ValidateSerial_Sample(MSIHANDLE hInstall)
{

TCHAR szPidKey[PIDKEY_LENGTH];
DWORD dwLen = sizeof(szPidKey) / sizeof(szPidKey[0]);

///retrieve the text entered by the user
UINT res = ::MsiGetProperty(hInstall, _T("PIDKEY"), szPidKey, &dwLen);
if(res != ERROR_SUCCESS)
{
//fail the installation
return 1;
}
bool snIsValid = true;
//validate the text from szPidKey according to your algorithm
//put the result in snIsValid

//the template we use is <###-####> = <xyz-abcd>; # digit between 0 and 9
//the algorithm is very simple (XY * Z + 7) * 13 = ABCD / 2
int xy = DIGIT(szPidKey[0]) * 10 + DIGIT(szPidKey[1]);
int z = DIGIT(szPidKey[2]);
int left = ((xy * z + 7) * 13 ) * 2;
int right = DIGIT(szPidKey[4]);
right = right * 10 + DIGIT(szPidKey[5]);
right = right * 10 + DIGIT(szPidKey[6]);
right = right * 10 + DIGIT(szPidKey[7]);

snIsValid = (left != 0) && (right != 0) && (left == right);
//

TCHAR * serialValid;
if(snIsValid)
serialValid = _T("TRUE");
else
{
//eventually say something to the user
::MessageBox(0, _T("Invalid Serial Number"), _T("Message"), MB_ICONSTOP);

serialValid = _T("FALSE");
}
res = ::MsiSetProperty(hInstall, _T("SERIAL_VALIDATION"), serialValid);
if(res != ERROR_SUCCESS)
{
return 1;
}
//the validation succeeded - even the serial is wrong
//if the SERIAL_VALIDATION was set to FALSE the installation
//willl not continue
return 0;
}

But i need to check for 15 digits . Can you please send the code for this .
Thanking you ,
Ovia

What about:

BOOL IsSerialNumberValid(...)
{
    if (_tcslen(szPidKey) != 15)
        return FALSE;
 
    for (int x = 0; x < 15; x++)
    {
        if (! isdigit(szPidKey[x]))
            return FALSE;
    }
 
    return TRUE;
}

The code is useable as it is, just copy and paste it in. Call it like you would any other function. However, after reading the rest of your original post, it's not going to help you that much because of the other validation you require.

Deleting resouce problem

hi,
i want to delete the resouce in such a way:
UpdateResource(
m_hModule,
"MY_RES_TYPE",
MAKEINTRESOURCE( IDR_MY_RES1 ),
MAKELANGID( LANG_NEUTRAL, SUBLANG_NEUTRAL ) ,
NULL,
0 );

MSDN:
If lpData is NULL, the specified resource is deleted from the executable file.

GetLastError ===87 — The parameter is incorrect. How can i handle this???

If i do this:
UpdateResource(
m_hModule,
"MY_RES_TYPE",
MAKEINTRESOURCE( IDR_MY_RES1 ),
MAKELANGID( LANG_NEUTRAL, SUBLANG_NEUTRAL ) ,
lpData,
1 );

UpdateResource(
m_hModule,
"MY_RES_TYPE",
MAKEINTRESOURCE( IDR_MY_RES1 ),
MAKELANGID( LANG_NEUTRAL, SUBLANG_NEUTRAL ) ,
NULL,
0 );

everything's going OK but resouce isn't deleted.

Are you sure that the resource exists? Did you call EndUpdateResource()?

the problem is with the resource type which shouldn't be put in quotes. The resource type should either be one of the default resource types(e.g. RT_STRING ) or it should be the result of calling MAKEINTRESOURCE macro

(ATL/COM/MFC/C++)
HI, I'm beginner about Window programming
I'd like to develop a small dll that has a function.
There is one text(txt file) loaded on IE.
The txt contains just a words like "Hello!!".
I've made that the "Hello!!" has focus of cursor.
I mean If I move cursor on "Hello!!"
then arrow-shaped cursor would be changed to hand-shape on a web page.

Now, If I click the "Hello!!",
the programe opens new dialog that has a static text.
The static text shows me "Hello!!".

That's all. How can I make this?
any reply, any URL contains some reference about this, offer me please.

Hello friends,

In vc++ it is possible to generate asm code for a particular cpp file. My question is

Since assembly language instruction is processor dependent, Can you please tell me on which mircroprocessor assembly level language does the vc++ tool can generate asm file.

Hoping for a positive reply.

It generates the listing for 386 and above. It uses the instruction set for 386 for the listing files.

It should do that for every processor the compiler is able to write code for.

ADSI/ Extracting NetBIOS name from DNS

Hi,

I want to extract NETBIOS name using DNS
For this I am using IADsNameTranslate object of ADSI API
This is the error message I am getting
error: 'IADsNameTranslate' undeclared identifier

It seems like that IADsNameTranslate is supported on Dot net compiler and not on Visual studio 6.0 compiler
Can someone confirm this and suggest some workaround.

Thanks and Regards
Ankur

You may need to install (or upgrade) the Platform SDK.

Check the requirements for IADsNameTranslate at MSDN[^]
