I need an array of CMenu pointers, so that I can loop through the array and do stuff like:
CMenu* pFlyOutMenu = new CMenu[sizeSub];
for (int i = 0; i less than sizeSub; i++)
{
pFlyOutMenu[i]->CreatePopupMenu();
pFlyOutMenu[i]->AppendMenu etc
}
I am doing something incredibly wrong  , but it says :
C:\BKView.cpp(264) : error C2819: type 'CMenu' does not have an overloaded member 'operator ->'
Appreciate your help,

You've declared pFlyOutMenu to be an array of CMenu's, not an array of pointers to CMenu's, hence:
CMenu* pFlyOutMenu = new CMenu[sizeSub];
for (int i = 0; i < sizeSub; i++)
{
pFlyOutMenu[i].CreatePopupMenu();
pFlyOutMenu[i].AppendMenu
etc
}

Hi all;
I'm using the CShellList class in a project I'm working on. I need to fill up a CComboBoxEx (as well as a CListCtrl) with what is normally seen in the drop-down of a CFileDialog, i.e., My Documents, Desktop, Network Neighborhood, etc. CShellList has calls to get the correct icon depending on the file extension, and it has calls to fill up an image list with the system icons [AttachSystemImageList()], but the position of a particular icon (say, Desktop) in this image list is variable. CShellList also has a GetImageListIcon(CString) which will retrieve the correct icon when passed "C:\\My Documents\\"; but I do not know what string to pass it (if one exists) that will get me the icons for the Desktop, Network Neighborhood, etc. I need to either a.) know what strings to pass it to retrieve the correct system icon, or b.) know how to detect what a particular icon in the image list filled by AttachSystemImageList() relates to. Any help would be greatly appreciated.
Thanks,
Thomas

Is it possible for an exe file that is running to open the same exe file and append data to it.
Thanks
|
|
|
|

I don't believe that this is possible, in a simple context. Rather you have to go about and copy the executable to some new file, append the data to the new file, and then write some special keys in the registry such that the next time Windows starts up, the original file is deleted and then the copy is renamed.

I am porting some code to be UNICODE compatible and I have run into a few snags, namely that there aren't one to one mappings for all functions to work with UNICODE. There are some that have one to one mappings like atoi -> _ttoi.
I have an atof() function that needs a UNICODE equivlant but there doesn't seem to be anything of the sort. How would one go about simulating this or finding a proper _ttof() like function?
Cheers,
Clint

I would like to display the standard hand pointer cursor over some buttons that are just images, and don't really look like buttons. I remember hearing that someone was able to read the graphic from some Windows DLL, and then use that as a resource instead of having to create their own. Does anyone have any suggestions on how to do this or could you point me to an article that has this?

No need to read any graphics from a DLL. LoadCursor(hInstance, IDC_HAND) is one way to acquire the hand pointer.
Do you implement these buttons yourself? If so, you could specify the hand pointer when you register the window class. If you don't register a new window class, I guess you could track the mouse cursor movements in and out of the button and use SetCursor appropriately.

Also another note is, set the cursor to be used in the WM_SETCURSOR message handler, not in WM_MOUSEMOVE etc as you get a flickering cursor as it switches between the default and WM_MOUSEMOVE one.

Wow, you have no idea how simple you made this for me! I had done something like this by subclassing my buttons and using WM_MOUSEMOVE but now everything is much nicer. I am curious though if my subclassing is causing a memory leak:
LRESULT CALLBACK ButtonProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
{
HCURSOR hCursorRHand = LoadCursor(hInst, MAKEINTRESOURCE(IDC_REDHAND));
switch(message)
{
case WM_SETCURSOR:
SetCursor(hCursorRHand);
return TRUE;
}
return CallWindowProc(DefButtonProc, hwnd, message, wParam, lParam);
}
The fact that I am calling LoadCursor and no DestroyCursor is that causing a leak because MSDN says there is no need to call DestroyCursor (or at least this is how I interpreted it). If it is causing a leak, where would I put DestroyCursor in this function?
|

You probably do have a resource leak in your code. You need to do LoadCursor() just the once and store the handle somewhere to re-use, as it is your leaking 1 cursor resource everytime the procedure is called.
I had some code a while back that was leaking icons, the results were very bad after a short period of time.

I am confused on the matter actually, MSDN states that LoadCursor will not load the cursor if it has already been loaded but that sounds fishy to me. I was also thinking to call DestroyCursor just before the function returns. I think that would probably take care of every LoadCursor call wouldn't it?

Hello all. I'd like to use something that approximates a Class Specific #define without using namespaces, static const's or enums. Actually enums in the class would be good except some of the defines are floating point numbers.
1 header file has #define MAX_LASER_POWER 23.3, another has #define MAX_LASER_POWER 44.0
Anybody have a clever way to elegantly encapsolate these defines?
Thanks in advance!
|
|
|
|

Well, you could try this:
class A
{
public:
static const double MAX_LASER_POWER;
};
[EDIT] Oops, I forgot the "const".
const double A::MAX_LASER_POWER = 23.3;
class B
{
public:
static const double MAX_LASER_POWER;
};
[EDIT] Oops, I forgot the "const".
const double B::MAX_LASER_POWER = 44.0;
You will get basically the same results as using a #define since they are const.

I want to write an SNMP extension agent for one of my applications, that run on a Windows 2000 server.
How do i return an array of values in a GET or GETNEXT request?
I made an MIB that looks like this:
What does the extension agent say when it gets a request for
enterprises.radical.software.apps.radicalserver.radicalserverinstance.serverconnections
since it actually points to a list of connection objects
Also how is the members of the connections array accessed. Is it like
enterprises.radical.software.apps.radicalserver.radicalserverinstance.serverconnections.0
enterprises.radical.software.apps.radicalserver.radicalserverinstance.serverconnections.1
etc....
