Oh man! If the C-library is designed to talk to the hardware directly, you may have a major problem! What I mean is that any modern system, based on NT or above (NT/Win2000/XP), will probably refuse to allow you direct access to the hardware (for security reasons). That means, you need a hardware driver (or to create one).
Google: "name of your library", iprintf, iscanf.
Maybe you will find something useful.

I'm using Visual Studio .Net to create C++ and ATL dll projects. We have a LARGE dll library, and I do not want to set the resource dll version info for each one.
Does anyone know of a way to override the dll version info that's compiled into the DLLs resources? I would like each DLL to return a common set of information (company name, copyright, etc.). Is there an override or callback that I can use to set that information at runtime?
Thanks,

There is... you have to write to the resource section of the dll file... search google, I'm sure you will find many examples of how to do this.
Don't try it, just do it!

The version information is embedded within the resources in a version information block.
You can build your modules with a common set of includes so that they all have the same information and therefore at runtime would present the same information to any tool querying the version information block. There is not an API to 'get version information' that is called within your modules, so there is nothing you can readily override at runtime.

Maybe I'm not understanding your reply, but isn't that what VerQueryValue(), GetFileVersionInfo(), and UpdateResource() are for?

Could be 
I REALLY believe he wanted to know if there was an API he could intercept or hijack so that when it was called from OUTSIDE his modules, he could return version information that was consistent. At least, that is how I interpeted the original question. Or, put yet another way, 'what function do I export that clients call to get my version information' and the answer to that is "there is not one that is standardized".
Therefore, he should build all his modules with consistent version information, and the easiest way to do that is to make them all include a common file with similar version information. If that is too much trouble, then, yes, a tool that plugs a version information resource into an already built module would suffice. Extra work and effort, but certainly doable.

This is a total newbie question, and am almost too embarased to ask it, but bear with me...
I created a program in VS.Net 2003 with windows forms, buttons, menus, etc... How to I run this program on other machines without VS.Net or any framework installed? I copied the .exe file from the debug folder, but it won't run on other machines
Any help would be appreciated (and a little newbie bashing will be tolerated)

You can't. The .Net framework is required on the target machine.

You must compile the program in Release mode and copy that version to the target machine.

So any program I create won't work on another computer unless it has the .Net framework installed, even if I compile it in Release mode?
|
|

|

Yes that is the advantage of .NET - redistributable of 20 MB or so... 
Of course, maybe it will be deployed already with future (maybe XP already has it...) operating systems.

There are tools out there that allow you to merge the framework with your exe and compile the MSIL to native code...
Strongly not recommended because your exe will not be serviceable (and a raft of other disadvantages). Just install the framework on the machine. period

I have not used VS.NET, but it should allow you to staticaly link to the libraries you are using. what that means is that the library becomes part of your program. In the passed that used to mean the entire library, but today it just means the parts that you actualy use. This will make you program much larger, depending on how much of it is linked to your program.
The main advatage of using DLLs, is that you may be sharing the library with other programs. If the creator of the DLL fixes minor errors in the DLL and the user update that same DLL, then the fixes also affect your program.
The disadvatage of using DLLs, is that you must redistibute the DLLs with your program (just incase your users do not have it installed).
As for DEBUG and RELEASE: The problem is exactly the same thing, you have to ether staticaly link the DLL libraries or install the libraries on the target machine. The only reason for installing a DEBUG version on a target machine is that it will give you some feed-back. You can accomplish that in the DEBUG or RELEASE version by setting your own a define statement, instead of using the _DEBUG statement. The advatage of useing the _DEBUG statement is that it will generate the ASSERT dialogbox on the the target machine. The disavantage is that MFC will (some-times) generate an invalid ASSERT dialogbox, meaning that the call will fail but do no damage (if youre handling the result, then no problem).
Sorry, I tend to get carried away.
Good Luck!.

How do I make the window for my program non-resizable?

One way is to remove the WS_THICKFRAME style.

In Continuation with Mr Crow, you can also handle WM_GETMINMAXINFO message to do so

While that message does affect the frame's size, it does nothing for the cursor which would still indicate that the frame could be sized.

Hi everyone,
I have a problem concerning the WM_LBUTTONDOWN message.
I'm subclassing a list view control using MFC to implement owner-draw abilities, and I'm using ON_WM_LBUTTONDOWN() in the message map.
BUT: When releasing the left button on the list view control nothing happens, the message handler only gets called when double-clicking the left mouse button...?
Any suggestions?
Alex

Maybe the WM_LBUTTONDOWD got reflected to the parent of the control?
|
|
|
|
|
Doesn't reflection work the other way 'round? In other words, by default messages go to the control's owner and then reflection reflects them back to the control so that message handling can be done in derived control classes?
|
|
|
|
|
Yes, that is the definition of reflection.

Excuse me. Maybe it was HANDLED by the parent, in which case it will not be reflected back to the control. MFC handler processing code will typically stop at the first handler it finds. If you have a stub handler in your parent window you 'forgot' about, you can scratch your head a long time trying to figure out why the 'reflected' message is never received by the control.

If you're looking for clicks on the list control, you need to be handling LVN and NM messages such as NM_CLICK
