Unit testing in C++

Hi,

I'm looking for a tutorial about Unit testing integrated in Visual studio.
I know that Visual Studio 2008 Team suite has the ability to write unit test(the problem is that
The unit test is written in managed C++ while my code is written in unmanaged c++).

Is there any tutorial?
How about another tools(for unmanaged code)?

With best regards,
Eli

Hi Eli,

I think that you should read the MSDN article Using Testing Tools in Visual Studio Professional Edition[^].

Another option is Boost[^]'s Test Library[^] (although it's not managed code).

UNICODE to MBCS problem

I use

WideCharToMultiByte(CP_ACP,0,pBuf,len,pBuf_MBCS,n,NULL,NULL);

to convert.
\n sometimes is converted to 0D 0A, and sometimes to 0A.

Who knows what's the problem?

How do you know that? What is your input string and what about the output one?

One string is very long, it compose a .txt file, about 50 lines, use \n as line break,
another is much shorter, less than 10 lines, also use \n as line break.

After converting, \n in the long one became \r\n, the other is sitll \n.

You may check, possibly with a hex editor (or the debugger), what are the actual linebreaks (i.e what are the UNICODE characters) of the two different strings.

Hi all,

How to generate beep sound or audio from a system not having speakers in VC++.Net?

I used Beep(freq,mili_secs) to generate a beep from motherboard.Will it work without sound card installed on system?
And how to know diffrent frequencies?

Yes, provided your system satisfy function requirements [^].

Documentation states that frequency maybe genrated in the "37 through 32,767" Hz range.

Newbie question, handling form focus messages

kensai19-Jul-08 10:45

19-Jul-08 10:45

I have a problem with MDI forms. An MDI form in my application sets focus to a control on it(also scrolls to its location) when the form is clicked/activated/focused. I'm looking a way to prevent it. This is actually a C# application and I have no C++/WinApi knowledge. I tried Spy++ and checked messages it recieves when the mdi form is activated and when this problem occurs. I saw several messages like WM_FOCUS and such. I checked the message number, e.g 0022, and overriden WndProc function of the mdi form and tried to handle it like "if(m.Msg == 0022 || m.Msg == 22)return" for all of the messages includes word "focus" but this didn't do any good. I don't know what else I can do.

This is actually a .NET question I posted here but I thought maybe someone with C++/WinApi knowledge could help me with this. It's driving me insane and I appreciate any help.

Hi,

I am using two differnt applications within one project in vc++.

For these I want to load two different application icons. However i dont want to another icon id. I want to use this same icon id. The reason is because i have all my menus,etc with this id. So i want to have this id but pointing to two differnt resource files, which would be decided in the compile time.

How to use/point a icon id to two different files programatically?

I don't understand the problem. Just make sure you assign the same values in the resource.h file.

this is a Borland C++ warning, and it works well under Visual C++ (no error). If you would like to skip this please put # pragma warn -8084.
