I got my copy of the book for $5 on ebay a while ago
If you want something free, from the visual studio IDE on any given CPP file type :: and a list of available API for whatever class you're using will pop up.

I got this API reference [^] which I use it a lot, because it is very convenient.

How do I create a folder in Outlook Express by code through modifying the "folders.dbx" file? Simple MAPI doesn't allow such operation. The only possible way I can think of is through its dbx file but I can't find any information which discusses so. The only information and codes available is how to read values from it (like folder info, or message info).
I really am stuck in here.. Kindly help.
Thanks..

hi all i am stuck in the slider control.
the situation is some what like this. my application lets call it A is using to capture the behaviour of another application called B. the Hook iam using is WndProc Hook and GetMessage Hook, my current slider code (which is not working) is in WndProc handler function.
there are 3 questions
a) in my code of WM_NOTIFY would i receive the slider notifications or not
b) or i have to use a separate case that is like WM_HSCROLL
i have done this approach but in this case i amnot receving any thing. the value in wParam is always zero.
c) if you look at the MSDN documentation of Slider Notifications there u have a number of notification with TB_ prefix so i have to deal with WM_HSCROLL or these TB_ sor of things
i am in urgent need of ur comments
thanx in advance for ur time
regards

HI all i am once again faced with a strange situation i guess the nature of my project is some what like this.
now the problem is that the application that would be tested by my software is a very rich UI application and the scenario is like this that every spin is placed ona dialog frame having the class #32770, for every soin there is a separate #32770 i have verified this from the handle.
the design time ID for the #32770 class is 202 but by using GetWindowLong during run time i always get the ID to be 0.
has any one experienced such situation if so kindly help me
regards
Thanx in advance

Hi,
I'd like a possibilty to include a "global define" (preferredly from an environment variable) in my builds
Is this possible? I'd like to avoid a "generic #include file")
(If it's important, the defines in question are for UNIT_TEST and "experimental" UNICODE support. I have already up to 4 configuraitons for some projects, and I don't want them to "explode" to 8 or 16 right now...)

what exactly do you mean.....you can for example define an environment variable like "somepath" which contains some path "C:\temp". This variable can be used in your project settings as $(somepath). Does this help any?
|
|
|
|
|
Yes, this is how it works for a path - I wonder if it works for a #define...

The /D compiler switch should help here. Use /DSYMBOL to simply define a symbol, or /DSYMBOL=value to give it a value.
I'm not sure whether you want the contents of the switch to come from an environment variable, or you want the put the define in an environment variable.
For the first case, you can use %PATH% or equivalent from the command line, or $(PATH) from inside Visual Studio.
For the second case, use the CL environment variable, but in this case you have to replace '=' with '#' when assigning values to the variables.
Hope this helps,

I can use
if(ndx=m_comboBox.GetCurSel()==LB_ERR) {
MessageBox("please,choose one of them !");
return;
}
for comboBox.
How can I warn when I use editBox?
emroz
|
|
|
|
|
CString s;
m_editBox.GetWindowText(s);
if(s.IsEmpty()){
.........
}
|

I dont exactly understand what you want,
but maybe:
if(a!=c)
((atof(a)/atof(e))*(atof(e)-atof(f)))/(atof(a)-atof(c))
of you will get a div by zero bugy some day.

if (m_edit.GetWindowTextLength() == 0)
MesssageBox("Please enter some text!", ...);

Hi everybody!
Can anybody tell me how to use BSTR and _bstr_t properly?
I have an array of _bstr_t strings putting them into this array like this:
<br />
_bstr_t* arr = new _bstr_t[100];<br />
<br />
arr[0] = L"string_one" + _bstr_t(BSTR_string) + L"string_three";<br />
arr[1] += L"string";<br />
My problem: Sometimes there are other array elements affected by changing the content of other ones!!!
Idea: It seems to be a problem of using pointers internally by _bstr_t or missing "SysAllocString" function use...

Hi all
I try to open file use _open routine with OF_BINARY|OF_RDWR|CF_CREAT|CF_TRUNC parameters but when i open first file _open("ffile",_O_BINARY|_O_RDWR|_O_CREAT|_O_TRUNC) file created fine.
But when i try to open another file _open("sfile",_O_BINARY|_O_RDWR|_O_CREAT|_O_TRUNC)file created too but have read only atribute.
Why this file has read only atribute, i use same parameters
as a first time but in first file dont have this atribute but in second time file have one??

Looking at the MSDN for _open it states:
The pmode argument is required only when _O_CREAT is specified. If the file already exists, pmode is ignored. Otherwise, pmode specifies the file permission settings, which are set when the new file is closed the first time
So basically you need to specify the 3rd argument to specify the permissions:
_open ("ffile",_O_BINARY|_O_RDWR|_O_CREAT|_O_TRUNC, _S_IREAD | _S_IWRITE )
I would image not giving the pmode in this case causes the subtle error you described.

If you browse the Platform SDK, and look at the overview for Tree View controls, it has a few paragraphs
about "Item States", which is what you are interested in.
Look up these member functions / messages as well:
CTreeCtrl::SetImageList (CImageList *, TVSIL_STATE) / TVM_SETIMAGELIST, TVSIL_STATE, (LPARAM)hImageList.

hi,
create a imagelist
.h
CImageList m_cImageList;
.cpp
populate event()
if (1) //bDoThisOnlyOnce
m_cImageList.Create(IDB_TREEVIEW, 16, 10, RGB (255, 0, 255));
//IDB_TREEVIEW resource bitmap with a the all icons
GetTreeCtrl().SetImageList(&m_cImageList, TVSIL_NORMAL);
rootitem = GetTreeCtrl().InsertItem(TVIF_PARAM | TVIF_TEXT | TVIF_IMAGE | TVIF_SELECTEDIMAGE, _T("RootItem"), ILI_CLOSED_FOLDER, ILI_CLOSED_FOLDER, 0, 0, -1, TVI_ROOT, TVI_SORT );
//ILI_CLOSED_FOLDER, ILI_CLOSED_FOLDER <- item nr of imagelist
Add msg
.h
afx_msg void OnItemexpanded(NMHDR* pNMHDR, LRESULT* pResult);
.cpp
void CMyTreeView::OnItemexpanding(NMHDR* pNMHDR, LRESULT* pResult)
{
NM_TREEVIEW* pNMTreeView = (NM_TREEVIEW*)pNMHDR;
HTREEITEM hItem = pNMTreeView->itemNew.hItem;
CString string;string = GetPathFromItem (hItem);
*pResult = FALSE;
int inImage, inSelectedImage;
if (pNMTreeView->action == TVE_EXPAND)
{
if (GetTreeCtrl().GetParentItem (hItem) == NULL )
{
GetTreeCtrl().GetItemImage( hItem, inImage, inSelectedImage );
if (inImage == ILI_CLOSED_FOLDER && inSelectedImage == ILI_CLOSED_FOLDER)
{
GetTreeCtrl().SetItemImage( hItem, ILI_OPEN_FOLDER, ILI_OPEN_FOLDER);
}
}
}
else
{ // pNMTreeView->action == TVE_COLLAPSE
if (GetTreeCtrl().GetParentItem (hItem) == NULL)
{
GetTreeCtrl().GetItemImage( hItem, inImage, inSelectedImage );
if (inImage == ILI_OPEN_FOLDER && inSelectedImage == ILI_OPEN_FOLDER)
{
GetTreeCtrl().SetItemImage( hItem, ILI_CLOSED_FOLDER, LI_CLOSED_FOLDER);
}
}
}
hope it helps
