Download and install a NEWER version of the Platform SDK and make VC point at the new libs and headers - your problem will be solved.
The original VC++ headers and libs were out before some of these newer functions, so it is not found in the WinSvc.H that you posess.
If you DO find it in your header, check for it bracketed by a WIN32 definition.

You need to do something like
#define _WIN32 0x0501
or some such value to make it visible.

They did this so you could target backlevel versions of OS with a build and be warned if you were 'linking' to functions that did not exist at the time.

Any sufficiently gross incompetence is nearly indistinguishable from malice.

Architecture Problem

Hi everyone,

since few weeks i look for a solution for my problem.

I like to open my MDI Children with Parameters.
For example if i click an element in a list, his ID will be the parameter for the new Child ( or another view with the details of this ID )

So, the new View must known which ID will be loaded...

Whats the best procedure ?

Big thanks Smile | :)

Override your base view class, and add a parameter in the overriden "Create" function to pass the ID.

Ok, but there i must derive many functions from the Template classes.

I startet like this:

i created a new class, derived from CMDIChildWnd
There i can store all informations i want.
At the Create-Event i associate with the Frame the View:

CCreateContext CC;
CC.m_pNewViewClass = RUNTIME_CLASS ( MyView );
CC.m_pCurrentFrame = this;
MyView* ActView = DYNAMIC_DOWNCAST( MyView, this->CreateView(&CC) );
if(ActView) {
ActView->ShowWindow(SW_SHOW);
ActView->OnInitialUpdate();
// Set this view active
SetActiveView(ActView);
RecalcLayout();

ActView->ResizeParentToFit(FALSE);
//RecalcLayout();
}

it works, but the border of the frame is displayed very confused.
The Minimize&Close Buttons are fixed ( aren't all the time in the right corner )
And the Dialog in the View has a wrong size ...

You have already made an application like this?

I'm more than one week over this problem Cry | :((

Thanks

LPCSTR

I have a difficulty...
when I want to make a LPCSTR variable, I do this:
LPCSTR test = TEXT ("hello");
Now I want to make a LPCSTR,including "hello" + name of a persion, which changes every time.
I can't do below:
CString name = "John";
LPCSTR test = TEXT ("hello" + name);
or
CString name = "John";
name = "hello" + name
LPCSTR test = TEXT (name);
please tell me how to do to achieve that result, or show me some pages related to changes of LPCSTR.

This should not be done.

Always use TCHAR types with TEXT and _T, else when you compile with _UNICODE defined it could lead to waste of time.

You can do likewise...

CString name = _T( "Nibu " );
name += _T( "Hello" );
LPCTSTR test = name;

There is no need to wrap name inside TEXT(). You should be careful when using statements like

LPCSTR test = name; // This will be fine till you do a unicode build.

So always adopt a generic approach. Try to use _T() or TEXT() wherever possible along with their counterparts like LPCTSTR.

Just a detail, but this should be

name = L("Hello")+name;

otherwise: "Nibu Hello" Roll eyes | :rolleyes:

Hello all
I have a dialog box on which a bitmap is loaded with LoadBitmap function . Its static . But if I change the display settings from 96 to 120 DPI then the dialog appears big but bitmap is not streched. Can anyone please tell me how to redraw my bitmap so that it fits to the dialog with new DPI ?

Hi
In fact i saw your answer , but I did not understand when you said the bitmap does not display .
In fact bitmap is displayed but it has not streched to the new size of dialog . The bitmap size remains static .Can you please help me how I can increase it to the new size due to increase in DPI from 96 to 120 ?

Hi static CLogoStretched m_BackgroundAddOnNoe;
static CBitmap m_BitmapAddOnNoe;

if(GetDlgItem(hDlg, IDB_MAP_ADDON_10_NOE))
{
if(m_BitmapAddOnNoe.LoadBitmap(IDB_BITMAP_ADDON_10_NOE))
{
VERIFY(m_BackgroundAddOnNoe.SubclassDlgItem(IDB_MAP_ADDON_10_NOE, CDialog::FromHandle(hDlg)));
m_BackgroundAddOnNoe.SetBitmap(&m_BitmapAddOnNoe, FALSE, FALSE);
}

}

Here IDB_BITMAP_ADDON_10_NOE is the bitmap which is loaded . CLogoStreched is defined as below
I do not understand the functionalities associated with CLogoStreched ...Please tell me what you get at it...

class AFX_EXT_CLASS CLogoStretched : public CStatic
{
// Construction
public:

CLogoStretched();

CBitmap* GetBitmap() { return m_pBitmap; }
void SetBitmap(CBitmap* pBitmap, BOOL bKeepRatio = TRUE, BOOL bTransparent = TRUE, COLORREF TranspColor = RGB(255,255,255), BOOL bResizeLogo = TRUE) { m_pBitmap = pBitmap; m_bKeepRatio = bKeepRatio; m_bTransparent = bTransparent; m_TranspColor = TranspColor; m_bResizeLogo = bResizeLogo;}
void ResetBitmap() { m_pBitmap = NULL; }

private:

CBitmap* m_pBitmap;
BOOL m_bKeepRatio;
BOOL m_bTransparent;
BOOL m_bResizeLogo;
COLORREF m_TranspColor;

// Overrides

Its not my answer you have two if,load bitmap and setbitmap to CStatic(m_BackgroundAddOnNoe) where you calculate sizes and use of streche.

Hi
The SetBitmap function and other functions of CStatic does not have any co-ordinate tranformation or DPI dependent functions.
So I feel CBitmap operations only should take care of the resizing issue. Have you got any ideas as to how I can stretch the bitmap from the CBitmap member m_BitmapAddOnNoe ?
I am desperate for help ....

Well you only increase size of window but for bitmap you need to StretchBlt your bitmap
and then set new hbitmap to your control.
