I thought there was some simple win32 function that I can just call to get the physical memory size.
GlobalMemoryStatus() returns that in MEMORYSTATUS::dwTotalPhys, however that doesn't tell you how much memory you can allocate. Virtual memory != physical memory. The amount depends on how much RAM you have, how much swap space is available, and what your process's current VM usage is like. Eg, if you try to allocate 1G of memory, your 2GB process space probably won't have 1G of continuous address space available, so the alloc won't work regardless of how much RAM you have.

Yes, I figured that was the case. Originally I asked if it was possible to find out how much memory I can allocate. Using the RAM size was something to fall back on. I'll use it to make crude estimations.

When I create a MSDE database within my application, I call OpenProcess() to open up a Access project file. This project file then starts up form that calls a subroutine. This subroutine needs the variable from my Visual C++ application in order to connect to the newly created database and display the tables. How do I go about doing this? Thanks!

How to crate new frame that independent with it parante.
|
|
|
|
|
Make your frame class and derive it from CFrameWnd. Create an object using your constructor. Then call CFrameWnd::Create(..) function on your object. Here's an example: CFrameWnd::Create(NULL, "", WS_POPUP, location,NULL,0,NULL);
I pass NULL as the argument for parent. Look up on MSDN what the other parameters are.

Form your method how i can call this frame.

Hi,
I'm trying to create a memory manager. And I'm doing that in such a way that using the new or malloc functions is out of the question.
The memory manager is allocating memory in the pagefile. First the manager allocates chunks of memory and then split that up into objects.
The problem I have is that I need to initialize the allocations with the custructor for the object requesting the memory.
Now how do I "call" or invoke the constructor for the object, without using new or malloc(or etc...)?
Any help or opinion would be appreciated...
Thanks,
|

A form of new called placement new[^] is exactly meant for what you need.

I want to set specific font for my tree, so I use CUSTOMDRAW event. I've write two functions that must set my own font, but they do not work
Please, help me. What is incorrect in my functions?
<br />
<br />
void CMyTree::OnNMCustomdraw(NMHDR *pNMHDR, LRESULT *pResult)<br />
{<br />
LPNMTVCUSTOMDRAW pNMTVCD = (LPNMTVCUSTOMDRAW) pNMHDR;<br />
HWND hWndTreeView = pNMHDR->hwndFrom;<br />
if (pNMHDR->code == NM_CUSTOMDRAW)<br />
*pResult = handleCustomDraw(hWndTreeView, pNMTVCD);<br />
<br />
*pResult = handleCustomDraw(hWndTreeView, pNMTVCD);<br />
}<br />
<br />
<br />
long CMyTree::handleCustomDraw(HWND hWndTreeView, LPNMTVCUSTOMDRAW pNMTVCD)<br />
{<br />
if (pNMTVCD==NULL)<br />
{<br />
return -1;<br />
}<br />
switch (pNMTVCD->nmcd.dwDrawStage)<br />
{ <br />
case CDDS_PREPAINT:<br />
{<br />
return (CDRF_NOTIFYPOSTPAINT | CDRF_NOTIFYITEMDRAW);<br />
}<br />
case CDDS_ITEMPREPAINT:<br />
{<br />
LOGFONT lf;<br />
lf.lfHeight = 20;<br />
lstrcpy(lf.lfFaceName, "Time New Roman");<br />
lf.lfWeight = FW_HEAVY;<br />
lf.lfItalic = TRUE;<br />
HFONT gh = CreateFontIndirect(&lf);;<br />
SelectObject(pNMTVCD->nmcd.hdc, &gh);<br />
return (CDRF_NOTIFYPOSTPAINT | CDRF_NEWFONT);<br />
}<br />
case CDDS_ITEMPOSTPAINT:<br />
{<br />
LOGFONT lf;<br />
lf.lfHeight = 20;<br />
lf.lfItalic = TRUE;<br />
lstrcpy(lf.lfFaceName, "Time New Roman");<br />
lf.lfWeight = FW_HEAVY;<br />
HFONT gh = CreateFontIndirect(&lf);;<br />
SelectObject(pNMTVCD->nmcd.hdc, &gh);<br />
return CDRF_DODEFAULT;<br />
} }<br />
<br />
}<br />
return 0;<br />
}<br />
<br />
Thank to everybody very much in advance..

What do you mean they "do not work"? Why are you creating a new font every single time? Have you checked your return values? (specifically that of CreateFontIndirect())

You are right. I simply tried to create font every time. I'll do it another way, now I only want it to work.

Does anyone have any suggestions on a C++ code profiler that works well with VS 7.1
I used to use TrueTime quite a while ago. Any suggestions would be most appreciated.

Thanks, I have downloaded a trial version and will evaluate it. My initial thoughts are that it is pretty good.

Hi,
aHandle = MyTree.InsertItem(....);
=> to create a new element into my treeview. My question is : how to delete this handle created by Microsoft function? When i try delete it by "delete aHandle" => it returns a warning message "warning C4150: deletion of pointer to incomplete type '_TREEITEM'; no destructor called".
Thank you.

it's only a handle to the inserted item, no need to do anything with it; BUT you will need to delete the tree item later on ( I'm too lazy to look and see if the tree items are automatically freed/deleted when deleting the tree ).

Are you sure the handle was created using the operator new

The handle is returned by Microsoft function InsertItem(...). This function create a new item and return it handle. I had try to delete this handle by "delete", "free" and "CloseHandle" but it does not work at all.
