I've got a situation where I have 2 related programs - one obtains and saves data, the other reads the saved data and processes it further. (Both programs are standalones, and not network enabled.) Since some of the initial processing and some of the final processing can share the use of certain classes (such as data access and file manipulation), I want to set up the IDE project to contain both programs, but utilize the same source files for those areas that are common.
Help me wrap my brain around this, since one project is not creating a lib or dll that the other one uses, but both are dependent on the same subset of files. What is a good way to set this up in the IDE, and what are the problems with this approach?

We did the same here until recently with projects. All we did was add the files (as in Project->Add files) which are in the other projects directory into the other project. As long as the headres can be picked up easily enough.
You could also put the files into a shared directory which Tools->Options.directories can point to to pick them up properly. Then add the .h/.cpp files to both projects.

Thanks, Roger. I guess I am stumbling over whether I should keep the shared files separately from the others, or whether to have them reside with one project and be accessed by the other. When using SourceSafe, updates to either project should be seen be the other project, but then it would make sense to keep them in a separate, common folder.
Right now, one project is much further along, and the other is practically just starting. All the files from the first project are stored in a directory, and I want to avoid having 2 copies of each of the shared files, but I want all the files for the second project stored in its own directory too.
I guess the best solution is to have directory for unique project A files, directory for unique project B files, and directory for shared files, but all accessed within the IDE as belonging to both projects.

Just a suggestion. Would a static library project for the shared files be useful?

The static library idea would be a nice way to keep everything all tidy, it would just have to undergo constant revision as more and more files from the first project were determined to be needed by the second. That shouldn't be a problem, though, as that is what the whole IDE/project system is supposed to make easier.
Thanks,

How do you get the killfocus for a CButton. There is a ON_BN_KILLFOCUS but that never comes. In the class wizard there is no option for killfocus.

Just a guess, but according to the platform SDK, buttons must have the BS_NOTIFY style set if you want them to send BN_KILLFOCUS. Does your button have that style set?

You probably can't get the KillFocus message because it doesn't propagate up to the button's parent window. So you need to derive your own class from CButton and then you can add a message handler for WM_KILLFOCUS.

WM_KILLFOCUS doesn't propagate up, but the button does send BN_KILLFOCUS to its parent window (if its BS_NOTIFY style is set) - so handling the BN_KILLFOCUS notification in the parent should work.

Cool, so he just needs to handle the WM_NOTIFY message on the parent and check for BN_KILLFOCUS along with the proper ID for the button.
Thanks for the info.

I neded a feature where I want my Dialog application to be versioned (Like a timestamp) whenever I recompile my file. I am unaware of methods to do this . Please help
|
|
|
|

See __DATE__, __TIME__, __TIMESTAMP__ predefined macros in MSDN library

http://www.codeproject.com/macro/incprivatebuild.asp
or search for auto-incrementing a version number here or on CodeGuru

My program when first opened takes up about 1K of memory. Then When open some dialogs and documents etc. the usage goes up.
Closing all the children doesn't shrink the usage, though, at least not by anything significant. However, when I minimize and maximize, I'm back to 1k.
Is this pretty normal? Does windows just assume the memory is still associated with my task, until it gets freed during minimize? Or does this signify I'm leaking memory?
I'm running Win2000, if it matters.
Thanks

What you are describing is normal behavior. I don't know exactly what Windows is doing, but minimizing an application does seem to flush the cache. If you want to know for certain if you are leaking, buy a copy of Bounds Checker or just run your application in the debugger. When you exit look at the output window and search for the word leak. These are only basic leaks that Visual Studio finds though; a new without delete. Bounds checker will find the more difficult leaks; like creating a com object and not calling release. But with any more sophisticated tool, you have a bigger learning curve and it can be frustrating to use.

Hi,
To use StrStrI, I
#include "shlwapi.h"
#pragma comment(lib, "shlwapi.lib") // link to shlwapi.lib
MSDN states: "shlwapi.dll 4.71 or later" (and, basically, IE4 must be installed)
However, on 98SE, even with IE6 installed, I get:
"missing export Shell32.dll:StrStrIA"
What's wrong? Do I need to write my own StrStrI? (I need to support 98, IE4 is no problem)

Because of the final "A", it sounds like a problem of ANSI/UNICODE versions of the function
is your code built UNICODE?

no, it's a straight MFC/ANSI build.
I'm a little bit confused by the dll name mismatch.

You probably need to define WINVER to be 0x0400 or 0x0500 or something like that

I have a controller program working like this. controller is set as a time event 1000/sec. But the "current_trials", sometime increments, even the controller doesn't go into state 1. why? Thank you.
controller()
{
static clock_t start_time, end_time;
if(state==1)
{
position= get_position();
set_force(position);
if(position > 10.0)
{
start_time= clock();
state = 2;
}
}
if(state==2)
{
end_idle = clock();
idle_time = (end_idle - start_idle);
if (idle_time >= IDLE_DURATION)
{
start_idle = end_idle = 0;
state=3;
}
}
else//state=3
{
position=get_position();
if(position < 0.5)
{
load_force_spatial_profile();//this is time consuming
state = 1;
current_trial++;
}
}
}

What is state intialised to, and where?
Also, your states are best described by an enum
e.g.
enum MyStates {ms_timing = 0, ms_loading, ms_state_to_be_defined, ms_error, ....};
This will make your program much more readable for yourself and others in the future.

Hello!
I wonder how you Gurus are managing all Error Messages in a large project?
I think that each Message should have a unique number, severity, text in current language, ... What else?
Do you number all error messages sequencially discarding severity or do you have one sequence per serverity?
Do you use the Message Compiler (mc)??
Are there any add-in for Managing Error Messages?
All input is valued!
Cheers!

Mike, sounds like you are asking about logging eh? There are as many ways to log as there are people to answer the question
You might consider using the OS log mechanism if that makes sense for your product. Otherwise you can do whatever you want. I've done logs with a UDP socket and a database for persistance. I've also done logging directly to disk files using XML.
You really need to consider your project specific requirements for logging. The main consideration in some projects like server side projects is to get logging working day ONE!  Makes life simpler.
