William,
using printf and friends, I don't believe you can, but check out gcvt in the documentation. While a little tricky to use, I believe it will let you do what you want.

Hi,
It's the first time I'm using ActiveX Control. I'm working with VS .NET 2003 and I must say that I'm a beginner to C++ and MFC. My problem is after I have inserted an ActiveX Control (any ActiveX control), I can't insert any other controls, like a Button, Edit Control, etc. I select the control I want and when I click to insert it where I want, nothing happen!
This problem is only in my main dialog: the CFormView dialog.
I need help here, I tried a few things, but without success!
Thanks,
Dave

Ok, I found out that the ActiveX control seems to be a coincidence. It's more like a have reach a limit on the quantity of controls I can have in my dialog!!! Is it possible?
I can insert one more control, and after that, no more control can be inserted!!!
I don't know why it's doing this!

The Visual C++ dialog edit only supports 256 controls on the dialog. Windows allows many more, of course, but you'll have to either manually edit the resource file, or create the controls at runtime.

Thanks, that's exactly my problem! I did a fast count of 249 controls! I'll redesign my dialog.

Hi. I have a webcam and I want to capture frames from the webcam in my application. I am using c++ mfc programming. The main thing that I want to do is to capture frames at certain interval through my mfc application. Anyone got any advise or idea on how to do it? Thank you for any reply.

what does MFC have to do with a webcam?!
this question is silly, because when u know how to capture from a webcam, then u know how to do it from MFC.
Don't try it, just do it!

You'll probably need the DirectX SDK. DirectShow has some examples that capture from cameras and display the output in a window (see the playcap example)

Hello
please if anyone can help me in solving this prob.! I have to implement a C++ program which adds any 2 long numbers such as : 12345654151464 + 454645454 , or any other 2 similar numbers. I should use classes for this problem!
so any suggestion please ?
thank u !

use __int64 for big numbers, for very big numbers you have to code an own lib.
Don't try it, just do it!

OLE/COM DECIMALs can hold 96 bit numbers. Take a look at the docs in MSDN.

Look into Audio part of this site.

sndPlaySound API

The simplest way to play an audio file on windows is to use the PlaySound function.

Putting a bitmap on a button? Depends on whether you're using mfc, wtl, win32 api, .net or something else. There's probably a dozen tutorials on this site alone explaining it, though.

I have an username & password inside my exe file. I opened it with notepad and saw they are in pain text somewhere inside it. Somebody told me that there is an compiler option that encrypt variables or something like this. Is there such a thing exist or he sucks?

nothing like that... encrypt it using a PE crypter or just save the MD5(or other) hash of the password.

Well, then the Key is visible and could be decrypted, but of course with a little more job.

As far as I know, there is no such compiler option. Your 'somebody' may have been thinking of an option to obfuscate .NET code.

If you embed a password directly into an exe, it will be insecure. You can play with it to make it less obvious (e.g. XOR against some other non-secret value), but nothing you can do will actually make it secure. If the exe has access to the password, so does anyone who has the exe.
|
|
|
|
|
If you absolutely must hard-code a password in the exe file, then I recommend you encrypt it, and then store the encrypted version in the exe. Then whenever you need to compare against it, encrypt the user-entered password and compare the encrypted passwords. I wouldn't do anything with plain-text passwords except encrypt them.

I have a SDI application with a splitter (left and right views). Left view is regular view(CView) created by the wizard. Right view is a form view with a pie chart drawed on it. Everytime i try to select File > New, it will give me assertion error. This is because of the pie chart, if i take out the drawing of the pie chart class on the right view then it works fine. However i need the pie chart to stay on there. How can i make this so when i hit File > New, it will try to open a new document on the Left view only and right view will not be reload or affected.
