Additionally to what Richard said, if you are working under windows, MSXML[^] might help you to parse XML files.

#defines in a static library

Albert Holguin28-Oct-11 10:30

28-Oct-11 10:30

Seem to be experiencing a bit of weirdness with a static library:

I have two #defines inside of the .lib (hex constants):

#define VAL_ONE 0x14fc
#define VAL_TWO 0x0050

Now, if I execute everything from the .lib as inline function from within the executable source (pretty much make it part of that compilation versus a static library), it works fine, but when it executes within the lib, somehow these values aren't getting assigned correctly to the structure that passes these values on to another function.

MY_STRUCT tmp;
tmp.value1 = VAL_ONE;
tmp.value2 = VAL_TWO;
//Where, value1 and value2 are defined as unsigned short values
//If I look at this on the debugger, value1 and value2 do not contain what I expect.

Am I missing/forgetting something?? D'Oh! | :doh:

Remember that it is all about substitution at compile time. The values you use when compiling the lib will be used there, and the values you use when compiling the exe will be used there. This means you will have to be careful when changing the values between compilations.

Are you saying that you have the same values in both projects and still experiencing problems?

Albert Holguin29-Oct-11 9:55

The #defines are in the header that gets used in the exe code for pulling in the functions in the static library... so it should be exactly the same. I've used this static library before and never had this issue before, which is even more odd.

The static library is a very plain/small library with only two small functions. There's no MFC, ATL, or anything like that in the static lib.

That is not correct, both the include file and the #defines within it are processed by the compiler, there is no reference to them in the exe or lib file. The actual #define directives are seen and converted to their 'real' values by the preprocessor. If you have different versions of the same directives within your project then you can end up with the situation you are seeing. Alternatively you could have a different set of values in the pre-compiled header file which conflict with the ones you are seeing in your .h file. Without seeing a bit more of your source it's difficult to speculate further as to why this is happening.

I was referring to where the defines are located within the projects. The source isn't that expansive and like I said, if I just move the functions into the header and make them inline so they aren't a separate compilation, it works fine, so there's nothing wrong with the source.

There obviously is something wrong with the source otherwise this problem would not exist. However without more details it's not easy to guess what.

I think we need to see a bit more of your code. Take a look at the actual values that are generated within the library build for the MY_STRUCT tmp;.

Do you have the defines in the header you have the funciton deffinition in, and that is included into the exe you are building?

==============================

Nothing to say.

See my comment[^] above to Niklas...

Erudite_Eric29-Oct-11 22:49

29-Oct-11 22:49

If the same header is used to complie the lib as the exe then the defines must be the same.

==============================

Nothing to say.

Erudite_Eric30-Oct-11 21:42

30-Oct-11 21:42

Yeah, so what you have is plain weird. Smile | :)

I am thinkin it may be a compiler screw up. Rare, but they can happen. Can you try a different compiler?

See note below to Josh btw... got it working, think the bogus numbers just came from breaking in the non-debug assembly... not sure why studio let's you break in a non-debug assembly if it's going to provide bogus data anyway... but at least everything is working.

Yep you're forgetting that the preprocessor is evil.

use...
static const uin16_t VAL_ONE = 0x14fc

Overlay icon in CListView

2-Nov-11 1:02

...I found a few mistakes on the linker inclusions coupled with the fact that I was breaking in the static library with the release version of the library, so think that was probably causing me to see bogus debug numbers (and the inclusion mistakes were causing the malfunctions).

I have MFC SDI project and CListView inside. I would like to have overlay images in my list control. In image list I have some images set with SetOverlayImage, and I use CListCtrl::SetItemState with LVIS_OVERLAYMASK and INDEXTOOVERLAYMASK. Overlay images are still not shown, just the main image. This is cleansed code:

C++

extern CListView* pLV;
CListCtrl* pLC = pLV->GetListCtrl();

imageList.Add((HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_MAIN_IMAGE), IMAGE_ICON, 32, 32, 0));
imageList.Add((HICON)LoadImage(GetModuleHandle(NULL), MAKEINTRESOURCE(IDI_OVERLAY_IMAGE), IMAGE_ICON, 32, 32, 0));

imageList.SetOverlayImage(1, 1);
pLC->SetImageList(&imageList, LVSIL_NORMAL);

pLC->InsertItem(0, _T("Testing"), 0);
pLC->SetItemState(0, INDEXTOOVERLAYMASK(1), LVIS_OVERLAYMASK);

What am I doing wrong?

What did you try to do to ready the file backwards?
What is the exact problem that you're facing?
Try and debug the program to see what and where the problem occurs.
