Your code is syntactically correct. What does the declaration of Curve look like?

Can someone point me in the right direction to find API for 802.11. I want to create an application to retreive/change the WEP key(s) of a wireless device via 802.11b in Visual C++. Is there a generic set of API's?

Never did it before, but might be, that IProvisioningProfileWireless::CreateProfile can help you as a search string in MSDN.

Hello,
i have an ip adress in CString format and I need to transform it in char [MAX_PATH] format ...
Does anybody have an idea how to do that ?
Thanks a lot for help and have a nice day !

You do not transform from a CString to a char array, but you can copy one to the other:
<br />
CString sTheIP( "192.168.0.1" );<br />
char caCharArray[ _MAX_PATH + 1 ];<br />
<br />
::strncpy( caCharArray, sTheIP, _MAX_PATH );<br />
caCharArray[ _MAX_PATH ] = '\0';<br />
If whatever you need to pass the char array to only needs a const char * (LPCSTR), you can pass the CString directly; it has an operator for const TCHAR *.
Peace!

Hi y'all
I used LockWindowUpdate to prevent my CListCtrl and CTreeCtrl from redrawing while the whole items were repopulated. It works fine, except that upon unlocking the whole desktop and all its child windows receive WM_PAINT messages...
I thought that only this mechanism operates only on the locked window... anyway, when I remove the LockWindowUpdate lines in my code, only my controls are flickering, the rest of the desktop remains untouched...
All this seems very strange to me...
Anybody else had similar experiences?
Regards
Daniel

Use WM_SETREDRAW. LockWindowUpdate is a nasty call that causes is lot of problems if not used properly.

Thanks for your suggestion. I tried it, and it seems to me that SetRedraw is not implemented for all controls. I'm using a CListCtrl and according to the MSDN doc they talk about CListBox in their examples...
Is there any other alternative?
Or what is the proper way of using LockWindowUpdate? It would work exacly how I want it to, except that the all open application windows receive WM_PAINT messages...

WM_SETREDRAW works for CListCtrl. I've used it. Avoid LockWindowUpdate like the plague.

Have a look at the docs for SetRedraw()[^].
It has a brief example for your CListCtrl class.
Being a CWnd derived function, it should also work for any CWnd derived controls.

If it doesn't work, then your code has other bugs in it. I know that doesn't really help you out a lot, but time and time again I see people waste time trying to figure out why the operating system isn't working when it turns out that our code just has a simple bug.
I'm not bitching at you or saying you are a bad programmer. We all do it. I recently wasted two hours trying to figure out why MFC's wait cursor wasn't working when it turned out I just forgot to specify a variable name.
i.e.
CWaitCursor;
instead of
CWaitCursor waitCursor;

Hi,
I get this runtime error
Unhandled exception at 0x7c59bbf3 in NewMumsEngine.exe: Microsoft C++ exception: std::out_of_range @ 0x016c605c.
when I try to execute this line
sVarData = m_pElement[iPos].sValue.substr(iIndex+1);
where
sVarData is of string type.
m_pElement[iPos] is an object of a structure
sValue is another string variable in the same structure.
Can anyone please explain this error to me and tell me how to remove it.Any suggestions please?
thanks,
Arjun.

You don't say what type m_pElement is but I presume it's a pointer to a C-style array. I'd therefore guess that iIndex + 1 is greater than the length of sValue, assuming that sValue is a std::string.
You probably need to check that iIndex is less than the length of sValue before performing this operation.
Stability. What an interesting concept. -- Chris Maunder

substr() throws out_of_range when the index is beyond the end of the string. Check the iIndex value.

What is difference between console based coding and event based coding
in window platform

The former runs in a console window (as opposed to GUI), while the latter is based on events (as opposed to synchronous). They are not necessarily mutually exclusive.

Hi All,
I want to build a structure of userdefined elements,which will be having child & subchild elemetnts as well(Like a Tree Structure). Using STL or so...
Is there any build-In facility in c++,by which I could create a tree structure like this & query for elements as well, within this structure.
If not any suggestions how to proceed.....
Thanks...

Try using an XMLDOMDoc. You can use XPath syntax to navigate the tree and find nodes. XML is a self-defining tree structure which includes it's own navigation functions. Sounds like a perfect answer to you problem.

hi,
recently i got some work which needed a good GUI. I did a lot of time googling but became even more confused. i hav seen stunning gui's like those of google's picasa, acdc6 ... How do they do it ?
Several sites advices to use a manifest file to make application Theme aware in XP. it works fine but only with Xp. should i go with using bitmaps for all the controls and dialog backgrounds, OR use a third party tool like BCG/codejock software.
I am a beginner and can anyone please give an advice on how to start with this. i am so desparate to make my controls and other parts of my application
look great. any help is highly appreciatable 
thankx,
abin

application like picasa manually draw their own GUI, either by using bitmaps, or simple GDI drawing.
Doing a complete UI package for your software can be time consumming, and should only be done if it's absolutly necessary, or that you have both time and money; BUT it can be really fun to do.
Also, have a look at topics that talk about skinning application.
