Ah (again). I think a better way would be to just override WM_NCPAINT and always render the caption bar as active. This will allow the modeless dialog to become inactive when necessary, but it will appear active to the user.

And how do I do about rendering the caption bar (independently of the Windows OS version installed) ? I mean, is there a way of calling a API method to do that?

(...) because only one window can be active at any one time in Windows. However, it has become normal practise for tool windows and main windows to appear active at the same time. I think it looks more natural this way, (...)
This is precisely how I feel and that is why I was looking (in vain) for a way to accomplish it.
Ravi, thanks a lot for those two brilliant links! You have indeed solved my problem.
Again, thanks for the time you've wasted on me.

Greetings,
I am currently using Microsoft Visual C++ to develop a GUI/UI for an I2C Read/Write program. Right now, I have a dialogue box implemented (a Resource file [.rc] that I included in the project). I believe I have the edit boxes working fine, where the user can enter certain parameters into blank boxes (i.e. start address, how many bytes), but the thing is, I have no way to check internal variables in my program, because there doesn't seem to be a way to "printf" values to the screen with a dialogue box.
Therefore, my essential question is: how do I output certain internal variables to the screen if I'm using a dialogue box interface? I essentially am looking for a "window" into my internal variables, maybe some type of text/edit box that continually "updates" with a new value of my internal variable - just something equivalent to a "printf" statement, but for a dialogue GUI box. Does anyone know how to do this? Any insight into this problem would be greatly appreciated.
Best Regards,
Tim Hsieh

pADOLogin is never defined, which is passed into GETRS. any ideas how the compiler or the runtime know what to do with pADOLogin a.k.a. db?
CString strSQL = "SELECT * FROM Login WHERE User_Name='" + m_strUserName + "'";
BOOL bLogin = VALIDATE_USER;
GETRS(pADOLogin, strSQL, m_strUserName, this);
#define GETRS(db, sql, user, pcs) \
CDBTier db;\
OPENRS(db, sql, user, pcs)
#define OPENRS(db, sql, user, pcs) \
TRY{\
WriteToLog(sql, user, __FILE__, __LINE__);\
db.CreateDispatch("WorkFlowDBTier.DBTier.1");\
if (db.m_lpDispatch != NULL)\
{ db.Open(0, m_strDataSource, user);\
if (m_bContentStarted)\
pcs->WriteResponseDebug(sql + CString("
"));\
db.OpenRecordset((COleVariant)sql);\
}\
else\
{ WriteToLog("\r\nUnable to Create DBTier Dispatch", user, __FILE__, __LINE__);return FALSE;}\
}CATCH_ALL(e)\
{\
WriteToLog("SQL Error:" + CString(sql), user, __FILE__, __LINE__, e);return FALSE;\
}END_CATCH_ALL

Have you tried placing the cursor on pADOLogin and pressing the F12 key? This should take you to the definition.

From the code GETRS(db, sql, user, pcs)
becomes
CDBTier db;
OPENRS(db, sql, user, pcs) // Note I have not expanded the OPENRS bit
Therefore pADOLogin is defined as a CDBTier object.

Thanks for your response. Normally functions and there prototypes require the datatype to be included in the function statement. I expected:
OPENRS(CDBTier db, CString sql, CString user, CString pcs); instead of OPENRS(db, sql, user, pcs)
Can you explain why this type of declaration isn't necessary?

In your example there isn't a function declaration it is a defined MACRO. When you use MACROs they are replaced with their associated code before compilation.
In your example I am not sure why MACROs have been declared as such. IMO they are un-necessary here. You could change the code to remove the macros and have appropriate functions to do the work for you.
I feel that it would be easier to maintain and understand if you made such changes. Not just for yourself, but for others that may need to maintain the code in future.

Is there an Windows API that I can use to extract the server's comment? For example, given server name //server1, I need its comment, such as Dave's fastest PC.
Thanks.

Sure, just use NetServerGetInfo(_T("\\\\server1"), 101, ...).

Does anyone know a good way to determine if a CWnd* represents a group box?
Joel Holdsworth
|
|
|
|
|
Group boxes are button controls with the BS_GROUPBOX style flag set.
So, the easy way would be to use the CWnd pointer to get the style flags (CWnd::GetStyle) and see if the DWORD contains BS_GROUPBOX. If it does, then it's a group box.

Yes but I seem to get "false positives" on things like static controls which also have the same flag set, but with different context... any ideas?
Joel Holdsworth

GetClassName should help you out. IIRC, you're looking for the class "BUTTON".

How are you checking for the BS_GROUPBOX style?

yes, but I seem to get some control's (like statics) which have that style set even though they are of course not groupboxes!
Joel Holdsworth
|
|

But are you checking for that style using the equality operator or the bitwise AND operator? It makes a big difference.
Otherwise, you'll also need to compare the class name as has already been suggested.

AFAIK I'm using the & operator.. although I don't have code in front of me to check it.
Joel Holdsworth
|
|

Check these two things:
1. Check for the style flag (BS_GROUPBOX)
2. Check the class name ("BUTTON")
It should be pretty fail-safe. If nothing else helps, then use Spy++ to get the style DWORD value of the group control and do a direct comparison. If you're using Dialog Editor to create your dialogs, it always creates "similar" group box controls.

I do not know if you figured this out already, but this is the code I use
(pWnd->IsKindOf(RUNTIME_CLASS(CButton))) &&
(((pWnd->GetStyle()) & BS_GROUPBOX) == BS_GROUPBOX)
BS_GROUPBOX is defined as 0x7 ( 0111 in binary ) so it is a combination of bits. Using just GetStyle() & BS_GROUPBOX will return a positive value if any one of the three bits are set (ie for BS_DEFPUSHBUTTON, BS_CHECKBOX, BS_AUTOCHECKBOX and BS_RADIOBUTTON). By checking for equality you ensure that all three bits are set.
