Hi,
when I print from my application, I always get 2 pages.
How do I resize the output so that it matches on one
page ?? (i.e. zooming to 75 % ??)
Thanks in advance,
Dennis Voss

I have (without success) been trying to use the SDK call GDIComment() (CDC::AddMetaFileComment()) to create groups in a drawing I put on the clipboard as a metafile. I'm sure I'm doing something stupid. Amazingly, there is little or no documentation of this in the Platform SDK.
Here is a simple example of what I'm trying to do (from OnDraw()), :
CPen pen(PS_SOLID, 2, RGB(0,0,0));
CPen* pOldPen = (CPen*)pDC->SelectObject(&pen);
#pragma pack(push, 1)
// byte array for begingroup
struct {
UINT ident;
DWORD iComment;
RECTL rclOutput;
DWORD nDescription;
} beginBuf;
// byte array for endgroup
struct {
UINT ident;
DWORD iComment;
} endBuf;
// if this is a metafile DC, create the first group
if (dynamic_cast<cmetafiledc*> (pDC))
{
beginBuf.ident = GDICOMMENT_IDENTIFIER;
beginBuf.iComment = GDICOMMENT_BEGINGROUP;
beginBuf.rclOutput.top = 0;
beginBuf.rclOutput.bottom = 200;
beginBuf.rclOutput.left = 0;
beginBuf.rclOutput.right = 200;
beginBuf.nDescription = 0;
BOOL bRet = ::GdiComment(pDC->GetSafeHdc(), sizeof(beginBuf), (const unsigned char *)&beginBuf);
if (!bRet)
{
ASSERT(0);
int iRet = GetLastError();
}
}
// draw an X
pDC->MoveTo(0,0);
pDC->LineTo(200,200);
pDC->MoveTo(200,0);
pDC->LineTo(0,200);
// end the first group
if (dynamic_cast<cmetafiledc*> (pDC))
{
endBuf.ident = GDICOMMENT_IDENTIFIER;
endBuf.iComment = GDICOMMENT_ENDGROUP;
BOOL bRet = ::GdiComment(pDC->GetSafeHdc(), sizeof(endBuf), (const unsigned char *)&endBuf);
if (!bRet)
{
ASSERT(0);
int iRet = GetLastError();
}
// begin the second group
beginBuf.ident = GDICOMMENT_IDENTIFIER;
beginBuf.iComment = GDICOMMENT_BEGINGROUP;
beginBuf.rclOutput.top = 205;
beginBuf.rclOutput.bottom = 415;
beginBuf.rclOutput.left = 0;
beginBuf.rclOutput.right = 200;
beginBuf.nDescription = 0;
bRet = ::GdiComment(pDC->GetSafeHdc(), sizeof(beginBuf), (const unsigned char *)&beginBuf);
if (!bRet)
{
ASSERT(0);
int iRet = GetLastError();
}
}
// draw an X further down the screen
pDC->MoveTo(0,210);
pDC->LineTo(200,410);
pDC->MoveTo(200,210);
pDC->LineTo(0,410);
// end the second group for a metafile DC
if (dynamic_cast<cmetafiledc*> (pDC))
{
endBuf.ident = GDICOMMENT_IDENTIFIER;
endBuf.iComment = GDICOMMENT_ENDGROUP;
BOOL bRet = ::GdiComment(pDC->GetSafeHdc(), sizeof(endBuf), (const unsigned char *)&endBuf);
if (!bRet)
{
ASSERT(0);
int iRet = GetLastError();
}
}
pDC->SelectObject(pOldPen);

Hi,
I'm writing an Add-In for Visual C++. I want to create a docking dialog bar of my own, that will dock the
Visual C++ window (similarly to the class/resource/file view dialog bar that's already there), but have
absolutely no idea how to idea. I've seen another Add-In that did it (it's commercial, so that there's no
source code).
There's an Add-In on this site (WinTabs) which implements a docking tab control. I tried to look for the
way it was done, but the code is rather complicated and big. I'm not even sure whether it would work for
a dialog bar.
Any help would be greatly appreciated
Thanks.

Thanks, but this doesn't help much, because what I'm trying
to do is create a child window (or a child dialog bar) to a
window from another process. Therefore, I have only a CWnd
object of that outer window but can't get its CFrameWnd.

We want to use some selfdefined ID's for the Toolbar Buttons.
Is there anything where I can look up the range of ID we are allowed to use?
We want to define them in a special header...
...like:
#define TOOLID_ZOOM 5666
Are there some ID's I am not allowed to use?
Is there anything about this in the MSDN (If...give me a keyword I can search for)
Thank you

Hi all,
I need to pass a function as a parameter of another function, but I don't know how to do it..
Example of what I want to achieve..
int function1 (int x, iny y);
BOOL function2 (int a, int b, function1)
{
return(function1(a,b)>0)
}
Can anyone help..

A simple example of what you are trying to do can be found in the EnumWindows function.
BOOL EnumWindows(
WNDENUMPROC lpEnumFunc,
LPARAM lParam
);
lpEnumFunc is the function passed in that is of type WNDENUMPROC, which is defined
typedef BOOL (CALLBACK* WNDENUMPROC)(HWND, LPARAM);
An example of a function of this type is
BOOL CALLBACK EnumWindowsProc(
HWND hwnd,
LPARAM lParam
);
So - define
typedef int (CALLBACK* MYFUNCTION)(int, int);
and then
BOOL CALLBACK function1(int x, iny y)
{
);
BOOL function2 (int a, int b, MYFUNCTION lpFunction)
{
return (lpFunction(a,b)>0);
}
BOOL bVar = function2(10,20, function1);
Note that callback functions like function1 must be static member functions, or globals.
Disclaimer: this is all off the top of my head - excuse any mistakes

I used the CDC::DrawDragRect in the OnMouseMove method and it generates the drag rectangle corectly only when moving from topleft to bottom right and all other directions result in the last rect not being erased ... what should be added for each mouse movement direction so that the drawdragrect functions normaly ?
|
|
|
|
|
It is advised to pass normalized rectangles to DrawDragRect() - call rect.NormalizeRect();

I'm a novice using VC++6 and speaking and writting english too, so excuse me if I ask something too easy or in an incorrect way.
I would like to print more than one page using MFC, and when I've detected the end of the current page I don't know how to tell VC++ that must begin another one.
Thank you in advance JCpp.

You must set up CPrintInfo Class. It has a Method
called SetMaxPage that would set up the number of pages you want to print.
Then you can use the following loop to print
CDC dc; // Printer dc obtained from Print Dialog
CPrintInfo info; // Printer info class
For(page=Info.GetMinPage();page

I've developed an NT Service and implemented event messages that are logged as application messages. The message compiler builds the .RC file and the .BIN file for me. The .RC file is compiled into the .RES file for the service. After I install and run the service, however when I look into the event log, I discover that while the differents events have been logged, the message assoicated with them is not available as part of the 'Details' of the event. I suspect that the .BIN file has to go somewhere, but I don't where. Anybody have a thought of what to look at?
Thanks.
Chris

You need to create an registry entry with the appname you use in the call to register the message.
HKEY_CURRENT_MACHINE(?)\SYSTEM\CurrentControlSet\Services \Eventlog\Application\myprog (i think)
The myprog subkey will contain several entries, one of which is the path to the file containing the resource format strings associated with the messages you are writing. In your case, this would be your service, but it could also be (and often is) a separate resource DLL.
When you invoke details on a message in the event viewer, it looks in the myprog key and tries to find the resource file specified so it can format the message for view.
There's an article on "EventLog Service Entries" in the MDSN that helps a bit - check the other reg entries to get an idea of what is needed.

The .BIN and .RC file from the message compiler end up being produced in the project directory. The need to be there so the resource compiler can find them. However after the service is installed, for some reason the event viewer, needs to find the .BIN file in the same directory as where the service has been registered. Once a put a copy there, all works fine. I've added a post build command to copy the .BIN files to the appropriate directory and I can forget all about it.
HTH somebody else!

I've found, that putting the binary messages into a dummy DLL works fine. All you do is create a dummy DLL, edit the Registry key for EventLog\Application to point at your DLL and it should work.
Just a suggestion.
Matthias
p.s.: I'm currently writing a simple tutorial "A total idiots guide to the Event Log". I will be posting it till the end of the week. So if you are patient enough...
