Instead of using Multiple Inheritance and deriving your class from CPropertyPage and CFontDialog you should be able to create a dialog template and include the CFontDialog inside of it, much the same way as you can with CFileDialog. I don't have the method to do this handy right now, but it involves creating a dialog template, and including a static or group box with a special id stc=0x30 or something like that. There are several examples on the net.
That should work, allthough I have not tried it yet.

Take a look at "advanced programming with Microsoft Visual C++" from microsoft press, at it's chapter 7 it explains nicely/easily how to insert common dialogs inside a normal one.
If you want you can insert a common dialog into a property page (in the same way).
If you don't have the book, send me a mail so I can send you the code that's inside the CDROM that came with the book.
Regards.

I would like to find a good site to learn about the C++ implementation of binary heaps. Does anybody know what's a good site to learn about this. I would like to find a site, for a beginner. A super simple little program would be very helpful. I really want to understand how is it that it works, its implementation, and where it's usually used.. Thanks;)

I'm a beginner here with probably a very easy question...
I'm looking to find how to get the largest value in a series of numbers, without using a function.
Any suggestions?
Thanks!

How about...
int nLargest = 0;
for( int i = 0; i < ARRAY_SIZE; i++ )
nLargest = __max( nLargest, ARRAY_ELEM[ i ] );???

Is is a programming question or a general "howto" question ?
Do you have a clue how you'd do it by telling me in your own word, without using code, just plain english ( or whatever human language we both understand )
If you can't derive a non-technical answer to this problem you need to think about it a bit more.
If it's a programming question, you have a bug with the code you wrote to solve this, then ask something a bit more precise.

Hi
There's a warning that is annoying me extremely, but I don't know how to get rid of it. Here it is:
Linker-Vorgang läuft...
Bibliothek Release/highlight.lib und Objekt Release/highlight.exp wird erstellt
highlight.exp : warning LNK4070: Die Direktive /OUT:hllaMIRC.dll in .EXP weicht vom Ausgabedateinamen "highlight.dll" ab; Direktive wird ignoriert
It is german, I try to translate it as far as I can:
"Library Release/highlight.lib and object Release/highlight.exp are being created
highlight.exp: warning LNK4070: the directive /out:hllaMIRC.dll in .exp differs from the output name "highlight.dll"; directive will be ignored."
thanks in advance

I think it's saying that the output name specified in your .def file is different to the one in the project settings. Trying making them the same and see what happens.

Hi
I'm developing an application which interfaces with Internet Explorer using COM.
I have a problem compiling my code due to typedef redefinitions. Whilst I understand the cause of the compiler error, I cannot figure a way around it. My application is #import'ing mshtml.tlb. This causes the compiler to automatically create 'mshtml.tlh', which redefines some existing typedefs. The worst thing, is that mshtml.tlh (which is not editable due it being regenerated every time you compile) defines UINT_PTR as an unsigned long *, so it differs with the existing definition which is of course unsigned int *.
None of these typedefs are mine, and i do not sepcifically include BaseTsd.h or WinGDI.h
I could really use some suggestions as to how i can resolve this problem.
Here's the output :
TestIEConnectWithCOM.cpp
c:\TestIEConnectWithCOM\Debug\mshtml.tlh(957) : error C2371: 'UINT_PTR' : redefinition; different basic types
c:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\Include\BaseTsd.h(90) : see declaration of 'UINT_PTR'
c:\TestIEConnectWithCOM\Debug\mshtml.tlh(76516) : error C2011: 'tagLOGFONTW' : 'struct' type redefinition
c:\Program Files\Microsoft Visual Studio .NET\Vc7\PlatformSDK\Include\WinGDI.h(1167) : see declaration of 'tagLOGFONTW'

I believe you can provide a different namespace name, to avoid the conflict. More info here[^].
|
|
|
|
|
Thanks for your reply. The article you linked me too has helped me fix the problem.
I'm not well acquainted with namespace's, and the article showed me you can exclude symbols as follows :
<br />
#import < mshtml.tlb > named_guids no_namespace exclude("UINT_PTR", "tagLOGFONTW")
Thanks again for you help.

I'm trying to take multiple small bitmaps, BitBlt them into a memory dc then
using a mask, draw them transparently to the screen. With one bitmap from a file it works fine, but when I combine them to an in memory DC and do the transparent blt, the colors get screwed up.
|
|
|
|
|
try to use TransparentBlt(), it uses chroma key to apply the transparency, and much easier
BOOL TransparentBlt(
HDC hdcDest,
int nXOriginDest,
int nYOriginDest,
int nWidthDest,
int hHeightDest,
HDC hdcSrc,
int nXOriginSrc,
int nYOriginSrc,
int nWidthSrc,
int nHeightSrc,
UINT crTransparent
);<pre>
if you are using VC++7 you will find it in the CDC class, otherwise you should use this API version

 I try to set bitmap on button but without success?
CButton xxx;
xxx.SetBitmap(::LoadBitmap(NULL,MAKEINTRESOURCE(IDB_BITMAP1)));
why this does not work?
Best regards,
Axe.

|
|
|
|
if you set the button syte to BS_BITMAP and the LoadBitmap returned a valid handle this function should work, otherwise somthing else may be wrong
|
|
|
|
|
which function is in the middle of CAppWin::OpenDocumentFile() and CDocument::OnFileOpen()?
because app crashes after call CAppWin::OpenDocumentFile() and before reach to CDocument::OnFileOpen().

Hi guys, I'm Pete an IT technician from the UK, previosly i only ever delt with Visual Basic but unfortunatly for a course i'm doing i have to write a program in C++ and everything i'm trying comes out wrong - i would be very greatfull if anyone could post examples of any code that could help me.
The task is to write the code for a simple ATM simulation
-When started a welcome message shoudl appear
-The user must then register their details to open an account
once the user has sucessfully registered their details a logon screen shoudl appear asking for thier pin number
-3 wrong pin numbers would result in the program shutting down
-A valid pin entry would take the user toa menu syetem with the following options.
Withdraw Cash
Deposit Cash
Request an overdraft
Quit
The program must display these menu options untill the quit option is chosen
An overdraft will be apporoved automatically if the user has over £500 in their account, if the user has between £250 and £500 then they must seek approval from their branch. if they have kess than £250 they overdraft request would be rejected.
I realise this is a long way below the levels of most of you guys but any ideas or sample codes would be greatly appreciated

I doubt you will receive any extensive help in terms of actual code. I recommend that you start the project and then post specific questions.

The other poster was right - we're glad to help, but we won't do your homework for you.
Pete Forster wrote:
#include //IO Library Mandatory
#include //Standard Library for DOS commands Mandatory
//#include //Includes String library
using namespace std; //For object orientation Mandatory
As a matter of form, it's better to use the syntax
using std::endl;
using std::cout;
etc. Do you *need* to use the dos library ? I think it's a bit ugly, personally.
Also, the includes didn't show up because you didn't tick 'display this message as-is', or use the buttons above the smileys to put in <> as < >. I presume you included <iostream> and <string> as opposed to <iostream.h> and <string.h> ? If not, the code is wrong and reference to namespace std is superfluous.
Pete Forster wrote:

Your while and if statements have semicolons after them. I suspect this is your main problem. The semicolon means that the code afterwards is always run. This can be valid, a loop and perform the desired actions by itself at times, but you want this
while (pin != 1234 && wrongpin <3 ) // no semicolon and extra brackets were superfluous.
{
++wrongpin; // Same as wrongpin = wrongpin + 1
// etc.
}
I'd also be inclined to use do...while loops so your input statement need only occur the once.
Pete Forster wrote:
while ((mmchoice !=1) && (mmchoice !=2) && (mmchoice !=3) && mmchoice !=4)
Just a suggestion, but this would be tighter as
while (mmchoice < 1 || mmchoice > 4)
Also, you created all these variables at the top, and a lot of them are just reused temporaries. C requires variables declared at the top, for C++, I prefer to declare them as I need them. They are only ints today, but if you're creating something resource hungry, it's better not to do it until you need it. ( Of course, if your teacher is an old C programmer, he may disagree and it may cost you marks, so ask him/her first )

Two problems here ( unless I'm misreading the code ).
1. 'Magic' numbers are evil. If you want to have a a limit, set it at the top of your code like this:
const int nMaximumWithdrawal = 500;
Then if you want to change the value later, you can do so easily without introducing bugs.
2. I suspect this code is supposed to refer to the customers balance to check if it's an overdraft, instead of a predefined value.
Good luck !!!
