That you are relying on Sleep(), and assuming that time is consistent between computers, especially if they are running different OSs. Read this article on why time is not always accurate.

Hello
I am working on a MFC SDI application.
On My one of the menu i am drawing something with the CDC which is Memory dc and is drawing in a bitmap.
Above mentioned CDC MemDC is global.
Now on Save
I am having two Options
save content of CDC to JPEG and
save as BMP.
Well I am using implementation fo ImageHandler (from Codeguru) so it works fine. With JPEG saving. It does uses the CDC for putting into JPEG image.
Now with BMP saving, previously i was using CDibSectionLite (from Codeguru) using the above Bitmap. I want to use CDC instead because of change in the design.
Is there any other way to save content of DC directly to the Bitmap file
Thanks in advance.

Hi there,
I'm a bit new to C++, been doing Java for a while now and I was just wondering if there is a way to get the 'Start Button' to appear as an entry in the context menu that appears when you right click on the desktop, if not any suggestions on how I should go about it?
Cheers,
/P/

First of all, i consider u r familiar with the VC++ IDE.
So, first of all, add a "Resource Script" to ur project. Then insert an MENU into it. Add a few feilds to the menu and give it a "DENTIFIER STRING".
Then to display a CONTEXT MENU u hav 2 write:
IN MFC:
void CMenuTestView::OnRButtonDown(UINT nFlags, CPoint point)
{
CMenu myMenu;
CMenu *ptrMenu;
myMenu.LoadMenu(IDR_MYMENU);
ptrMenu=myMenu.GetSubMenu(0);
ClientToScreen(&point);
ptrMenu->TrackPopupMenu
(
TPM_LEFTALIGN|TPM_RIGHTBUTTON,
point.x,
point.y,
this,
NULL
);
CView::OnRButtonDown(nFlags, point);
}
IN WINDOWS API:
case WM_RBUTTONDOWN:
POINT p;
GetCursorPos(&p);
TrackPopupMenu(GetSubMenu(LoadMenu(gloInst,"MYMENU"),0),
TPM_LEFTALIGN | TPM_LEFTBUTTON,p.x,p.y,0,hwnd,NULL);
break;
...Avenger
Remember... testing & debugging are always part of programming ...so exterminate those stinking bugs

Hi!,
I want to create a read-only view of excel,word or powerpoint file using the ole techonology.
I use the default object handler provided in ole32.dll
I dont know what steps to follow after creating the object using:
hr=CoCreateInstance(clsid,NULL,CLSCTX_INPROC_HANDLER,
IID_IUnknown,(PVOID*)&pUkwn);
the object handler basically implements IDataObject,IOleCache and IViewObject.
IViewObject::Draw will draw on the specified device.
but before that I want to pass data to the object.
which interface shall I use?
thanks

Im getting this error in a project Im working on, its referencing a .cpp file with function definitions, Im using the same .h & .cpp file on their own just using a main.cpp to test it and it works fine, but when I brought it over to the larger project I get this error:
fatal error C1010: unexpected end of file while looking for precompiled header directive.
I checked the MSDN library and it was of absolutly no help whatsoever, I dont know what it even means. Im using VC7 with win2k.
Cheers

arf, i've already seen that error, and i've got abslolutely no idea about its cause.
To avoid that, check Your project settings and disable the precompiled headers... it will work.
if anybody know about the reason this error occurs, let us know !!

put #include "stdafx.h" at the top of the file.
Or, go to project->settings and select the file. Go to C++->Precompiled Headers and set it to "Not using precompiled headers"
|
|
|
|
|
Your larger project is setup to use precompiled headers. This allows you to setup a set of include files that are used through-out your project and have them compiled just once. This is normally done by including the required headers in stdafx.h. Then when compiling the project VC++ expects stdafx.h to be included at the start of each .cpp file.
Just add #include "stdafx.h" to the start of the new .cpp file.

Someone asked me this question this morning - and I didn't have an answer. Can anyone explain why it is bad to use a macro function?
Dylan
|
|
|
|
|
because there is no controle on the parameters passed to it. second reason, we are obliged not to separate the macro name and the opening parenthesis '(' that follow it, which is not very practical.

Only in the macro's definition, not its usage.

Here is the classic example:
#define tolower(x) (isupper(x)?(x)-32: (x))
*pOut++ = tolower(*pIn++);
What does that expand to?
*pOut++ = (isupper(*pIn++)?(*pIn++)-32: (*pIn++));
Due to the expansion, pIn will be incremented twice. This is a behavior that is totally different from what is expected when tolower is defined as a function.
Here is another example
#define DOADD5(x) x+5
int iOutput = DOADD32(1)*2;
What is the result, 12? Nope, the result is 11.
When you look at the expansion, you get 1+5*2. Do to operator precedence, you get 5*2 then add 1 instead of 1+5 then times 2.
Some of these problems can be avoided, some can not.

Whether it is always bad is a matter of opinion.
Bad things about macros:
1) No direct validation of arguments.
2) Micro expansion could lead to unexpected results.
Examples:
#define MUL(a,b) (a*b) // bad macro
MUL(123-45,678-90) expands to (123-45*678-90) equals -30477
#define MUL2(a,b) ((a)*(b)) // better macro
MUL(123-45,678-90) expands to ((123-45)*(678-90)) equals 45864
Good things about function inlining:
1) Arguments are validated at compile time.
2) There is no expansion of arguments; therefore no misunderstanding of what the result will be.
Example:
inline int Mul(int a, int b) { return a * b; }
Mul(123-45,678-90) equals 45864
