Yes, it is possible.
First, you'll probably want to clone your current "Release" configuration, so you can have a "Baisc Release" and "Professional Release". (In VS.NET, there is a "Configuration Manager" button if you go to Project Settings, you can do it there. I forget where it is in VS 6.)
Once you've done that, you can go to your Project settings, C/C++, Preprocessor, and there is a line saying "Preprocessor definitions". Just add, say, _BASICRELEASE as a preprocessor definition for the "Basic Release", etc.

I have recently spent some time getting some of my apps looking right on XP styles, by adding a manifest resource, and also modifying some controls that are custom-drawn.
However, if I use my xp-style-enabled controls in apps which do not have a manifest, and therefore draw using the old style, I find that my controls still draw with the current XP style. I have used IsAppThemed() as a way of determining how to draw my controls, but I have found that this returns TRUE even though the app is not XP-style-enabled, making the control look odd! I have tried using IsThemeActive but this also always returns TRUE.
Does anyone know how I can find out if the app is XP-styled (ie the other controls are using the XP-styles)?

Dear Friends,
I would like to develop an application, which can display a image to a Projector instead of a Dialog's Display.
Please help to solve this problem. Is it possible to display the Dialog's display on a Projector? Any kind of suggesion will be highly appriciable. Please help me soon.
Thanking you in advance.

Do you mean something like this that connects to the video card's S-video port?

Yes,
But I would like to develop an application which captures an image from camera and display it to a Projector.
Waiting for your response.........

I don't see that anything extra is required. Just display the image as you normally would, and if a projector is connected to the video card's S-video port, it will show up there too.

Does anyone know if it is possible to have a lib file that will contain a program which when a method (i.e. Run) is accessed by an external program the program in the lib file will start up a new thread and then execute itself whilst allowing the other program to carry on running?
If so is there any pitfalls I should be wary of and also is there any examples of how to do this? (I've never done libs before though I have done threading).
If it is not possible is there any other way of doing this? (the aim is 'fake' the combing of two programs together so that they appear as one, unfortunately bother programs need to be running at the same time and at present they communicate together using sockets). We cant just put the code straight into the other project and have it as a thread in it as the owners of the other program aren't allowed access to the source code for this program.
Not to sure I've explained this well, so if I havent then let me know and I'll try to give more details.
cheers,
Andy

I'll take a shot at describing what I've done in the past and you can decide if it is similar to what you are doing.
Let's say you have an MFC application project which contains some kind of user interface and application implementation. Let's also say that the application must link to a few, possibly many .lib files in order to build and link. It could be that the main app project is mostly the user interface and gui implementation and perhaps you have a complex situation where once the user configures something through the GUI, some complicated thread has to be started and will perform some task (such as opening a socket to some communication device such as an ethernet port or some other kind of port).
So you might have a lot of your code that is building and processing messages in an MFC extension DLL. So you must write that code within the DLL, compile it and have your application link to the resulting .lib files. Within the DLL, you would have exported a function, such as a RUN function of some kind, that the main application links to and calls. Perhaps the RUN function then uses AfxBeginThread to launch a thread which runs on it's own and performs whatever task it was designed to do. Meanwhile, Run returns to the main app which can move on to whatever task it needs to do next. I'm not sure if that is what you meant by Program within a lib file. The lib file is for linking but the .dll file is in the directory where the one and only .exe file and will contain run time info.
So if this concept is similar to what you are inquiring about, yes it can be done rather easily. Just don't forget to add some stop method along with the run method so that a thread shutdown method can be implemented to prevent crashes and memory leaks when the program is shut down. In my example, I'm really referring to one actual process (.exe) which links to .dll files containing functions that can be called. The .dll could also contain classes which contain the thread start stop functionality and that would be more OO. So perhaps the main app would link to a class that it could instantiate, and upon instantiation the class would launch it's own internal thread and kill the thread when the object is eventually destroyed using 'delete'.
Hope that helps; either way, my fingers got some good exercise.
Best Regards,
Shawn

Hi, try adding the image to you ressources then in the html use
<BODY background="res:/IMAGES/#144">
where IMAGES is the ressource type and 144 is the ressource ID.

Hi,
I'd like to write a small DLL using MFC, which only should have a small dialog, and print some details on a printer. I'd like to call that DLL and display it's dialog from various MFC apps.
I simply don't know how to build an MFC-DLL containig a dialog, and what to notice. Do you have any hints for me how to begin, or a link to a tutorial?
Thank you very much in advance,
Erik

Select New from the File menu. On the New dialog, select the Projects tab. Select MFC AppWizard (dll), give the project a name, and click the OK button. Decide if you want a regular DLL or an MFC Extension DLL, and click the Finish button. Select Resource from the Insert menu. Select Dialog and click the New button. Populate the dialog template as necessary.
There are a few more steps (e.g., an exported function that will invoke the dialog) but these should get you headed in the right direction.

Hi all,
I've wrote an application based on the DirectX StillCap example, which allows the user to get the latest frame and then performs whatever segmentation methods they want on it. The problem which I have came across is that I appear to have more data than I am expecting! I'm expecting an 320x240 RGB image but the buffer I get is 233,472 long instead of 230,400 (i.e. 320x240x3).
Does anyone know what these extra 3,072 bits are (I'm guessing they may be header information)? And also where abouts in the stream they are appearing? as I'm not missing any information from the image when I save it so I'm assuming that is is probably at the end of the buffer (I've saved the buffer as a RAW image and then opened it up in Paint Shop Pro and everything appears fine)
Many Thanks,
Andy

Hi All,
searched high 'n low, and can't find a function/or where to look, to see if a system has usb ports installed. don't need to know what the devices are, just if the motherboard has a usb port.
needs to be c/c++, no wmi, function must be compatible with w98/w2k/xp
any help or advice appreciated

You might try the Win32_USBController and Win32_USBControllerDevice WMI classes.

Hi David,
thanks for he info, but i can't use WMI, gonna make the app too fat for its purpose with com and all the other stuff.
plus the app needs to run and detect on w98 systems, which WMI is not activated by default, and the end users are not bright enough to start hacking the registry.
any way with using WMI ??
thanks again

is there an easy 1 line or inline way of converting a CString into a basic_string of TCHARs?

How about:
string str;
CString cstr("Hello");
str = (LPCTSTR) cstr;or:
basic_string<TCHAR> str;
CString cstr("Hello");
str = (LPCTSTR) cstr;

I want suggestions with the things needed to be considered when am doing
1.Encryption of a file with AES(RIJNDAEL) algorithum using javax.crypto.* in a java application. and
2.Decryption of the encrypted stuff mentioned above in VC++ .
To be more clear,i am encrypting a file using the java 1.4 libraries and wants to decrypt the same encrypted file using VC++.

The encryption library should not affect the underlying algorithm. In other words, you should be able to encrypt the data using one library and then decrypt it using a different library.

If I call AfxEndThread within a thread will the dynamic memory that I have allocated in this thread be released or just the memory that MFC itself have allocated for it's inner needs. Thanks.
