C / C++ / MFC

20-Jul-11 21:49

"UnitTest" is on the VC's main menu,I want to use itto test my C++ code, but I am not familiar with its mechanism.
I wrote a little code expecting to learn how it works.But seems not work.
here's my code

class myClass
{
private:
	int m_i ;
public:
	myClass( int i ):m_i(i){ }
	BOOL EQ( int i )
	{
		if( m_i == i )
			return TRUE ;
		else 
			return FALSE ;
	}
} ;

int main()
{
	myClass mc( 10 ) ;
}

I click "new UnitTest", go through a few steps,when trying click the checkbox besides my project name, there's always a msg reporting unsuccessful "Unknown virtual address 0".

Waiting for help...

I haven't used the tool myself, but isn't there a startup guide to make us understanding the procedure to be followed.
Also, you can refer the articles on MSDN and I sure you will find more than one that will guide you further.

Certainly good advice, but I have to say it may not be easy to find useful material: I've faced almost the same problem, and my searches turned up tons of Tools for Unit-Testing or Tutorials for using such tools, but virtually nothing about how to set up a unit test in the first place! Frown | :(

Maybe an explicit search at specific sites such as MSDN or various technical forums might help - I haven't tried that yet.

Yeah, I searched lot, still haven't found too much helpful materials.I think I should give up using it since it related tightly with netFramework.Someone says C++ test is one of the best UnitTest tool, I'll have a try.

Stefan_Lang21-Jul-11 2:55

Indeed. I've been spending the last hour to find something more useful, and have all but given up. At the moment I'm digesting the entries on Unit testing that I've found on Wikipedia, just to be make sure I fully understand the concepts. Maybe that's a good place for you to look too?

Thanks, Stefan. I'll take a look.I love Wiki too. It was the place that taught me how to do the matrix multiplication.Hoho Smile | :)

This might help: Unit-Testing Native C++ with Visual Studio[^]

By using the Unit Testing framework in Visual Studio, then you should automatically get the ability to see code coverage (Though it requires one of the expensive Visual Studio Editions)

Print command to printer using PostMessage?

Hello to all,
I have written a VC++(MFC) application in which one of our USB connectivity device gets connected to computer and I continuously collect the data from that device. I display that data on screen and also when I give print command to printer through my application then that data gets printed on paper.

Now my problem is that, when I give print command to printer then it interrupts or stops data collection from the device untill the printing process gets completed but due to this we loose data from the device. So is there any way to handle printing process independently? Means can we give print command to printer using "PostMessage" or using seperate thread so that it will not stop data collection from device? or is there any other way to do this?

This is really very very urgent so please please help me out.

Thanks and Regards

Anay

I would suggest using threads or even a separate program to do the printing. A lot depends on where you are storing the data that you are collecting.

How to get the title text CTabCtrl's tabs?
The following code is crashing at the last line:

TCITEM tcItem;<br />
tcItem.mask = TCIF_TEXT;<br />
m_ReportTabCtrl.GetItem(ID_PANE_FOUND, &tcItem);<br />
CString csText = tcItem.pszText;<br />

Thanks & Regards

You did not initialise your TCITEM structure properly; see the MSDN documentation here[^]. It would be better to check the return value from all Windows function calls rather than just assuming that they have succeeded.

Thanks, It is working after initializing all the required members tcItem.pszText and tcItem.cchTextMax along with tcItem.mask.

I have a relativ simple (SDI) VC6 project that, because system tray notification ( showing ballon ) I have to compile in a newly environment ... I choose VS2008. I prefer to compile in a dynamic MFC library but I front with several linking errors :

I never used VS2008, what should I do to solve the problem ?

Re: VC6 to VC2008 migration

19-Jul-11 22:04

I got similar errors when moving from 2003 to 2010 recently. The cause was a static library that was part of my project that bound the runtime library statically rather than dynamically. For some reason this was never a problem before, but VS 2010 didn't like it.

My advice is check the libs that are part of your solution and make sure they all use the same settings regarding the runtime library being used. note that it doesn't matter whether the lib is bound statically or dynamically to your executable - the main point is that all libs must use the same version of the runtime library. (and I believe the same is true for the choice of MFC library)

Why debugging doesn't work properly when I choose "USE PRECOMPILED HEADER"?

20-Jul-11 19:51

Was the libcmt.lib problem : in project settings, link, input, I ignore libcmt library and goes almoust fine ... I set manually manifest.xml, and didn't like it to VS2008.

Re: Why debugging doesn't work properly when I choose "USE PRECOMPILED HEADER"?

<< VS2008 professional edition >>
If I use precompiled header "stdafx.h", sometimes debugging just doesn't work well, some of the variable value don't show up. Then I turned off using precompiled file, everything gets back to normal.It's only my prolbem? or does it ever happen to you, could there be a solution ?

Richard MacCutchan19-Jul-11 21:44

This is most unlikely; what is more likely is that you have some old information in your .PCH file (or in stdafx.h) that is causing the problem. Try doing a CLEAN and rebuild and check again what is happening. It would be useful to look closely at exactly what just doesn't work well and give specific details if it happens again.

Thanks for reply, I thihnk you're right.
Although it was the variables that from my cpp file didn't show up and leave the poor blue-cube(stands for variable)lonely there, I still believe it's my stdafx.h going awry.
