I want to put toolbar on top(upper side) of the desktop.
I don't want to put it over the desktop background or over the icons.
Is there a way to change size of Desktop ?
Is Desktop regular window ?
Thank you

This article - while old - is still the reference work for desktop toolbars. Windows automatically shifts the icons out of the way for such toobars, but since the desktop background covers the entire desktop, it is not possible not to cover it (at least partially).

How to calculate the size of a function?

At run time it is difficult to do, unless you have access to the .obj file. If you do, you can parse the file (see Microsoft Portable Executable and Common Object File Format Specification) and look for the size record for the function you are interested in.
To experiment with this, take a .obj file that contains a single function, and run this from the command line:
dumpdin /all myobj.obj > foo.txt The file foo.txt will contain a complete dump of the file, and you should see a record that looks like
0F2 00000000 SECT27 notype () External | ?GetFontProperties@@YAHPBDPAU_tagFONT_PROPERTIES@@@Z (int __cdecl GetFontProperties(char const *,struct _tagFONT_PROPERTIES *))
tag index 00000106 size 00000C7D lines 0000856D next function 00000111In this example, I used the XFont.obj from my XFont article. You can see that the size of GetFontProperties() is given as hex 00000C7D.
Note that these sizes are not exact - if you read the PE Format spec, you will find more info.
Just out of curiosity, why do you want to do this?

There are several articles here on CP on how to do this. I have used this one myself.

I have a display that simulates a digital scope. In my OnDraw rutine I draw the scope with scales and grid lines. I receive data via Ethernet and plot it in the scope. I'm using double buffering to minimized the flicker, though I'm pretty sure I'm not implementing it correctly.
Is there any way to save my memory bitmap or the memory DC so that I can Bit Blit it, when there is no data change, instead of redrawing everything again and then blitting it?
Also, if anyone can point me in the direction on some good articles that talk about double buffering I would greatly appreciate it.
Thanks,
Paul

Error C2660: 'MyPrintUnit::MyPrintUnit' : function does not take 1 parameters
I basically added the 4 files from his zip archive, and then copied and pasted his example usage into his source files, but am getting this error. It looks like MyPrintUnit is derived from GPrintUnit and its this base class that has the 1 parameter constructor, but have I done something wrong, or is it his mistake, or is there a way for me to call the base class version of MyPrintUnit in GPrintUnit
void MyPrintJob::OnPrint()
{
MyPrintUnit unit(this);
unit.Print();
}
note:
class MyPrintUnit : public GPrintUnit
{
public:
MyPrintUnit() {;}
virtual ~MyPrintUnit() {;}
virtual void DefineColHeadings();
virtual void CreatePrintFonts();
void InitPrintMetrics();
virtual BOOL Print();
CFont m_fontHeading;
CFont m_fontBody;
CFont m_fontHeader;
CFont m_fontFooter;
};
class GPrintUnit : public CObject
{
public:
GPrintUnit(GPrintJob *pJob=NULL);
....
etc

The compiler is telling you the exact problem. You are constructing a MyPrintUnit object with one argument when it is expecting none.

yes, I understand that, I think I said that in the original post. What i don't understand is why. I assume as it's an article on the website it's been compiled and working on someone's PC. It looks like it's trying to construct with the base class constructor.
If I take out the "this" and construct without parameters then the next line unit.Print(); does not work
error C2228: left of '.Print' must have class/struct/union type
Are you saying that this article is broken (the follow up replies don't seem to indicate this) or am I doing something wrong?

ldsdbomber wrote: Are you saying that this article is broken
In one word, yes.
The sample code is just that - I don't think it was ever compiled. There are obvious errors in it, not even counting the one you stumbled on. Here's the deal: If you look at the unit_table1.h file, you will see that the ctor is defined as
Table1Unit(GPrintJob *pJob);
That is what you must do.
Please post again if you have further questions.

Thanks,
sorry I didn't realise the articles here hadn't been vetted, I'll be careful in future!

The problem is that the listing of the sample code in the article was never compiled, although the demo code (in the zip download) obviously was.

Then you've got something else wrong, or have made a change elsewhere that you've not shown. The MyPrintUnit object can be constructed with no arguments.
I put the following in an existing project and it compiled fine:
#include "gfx_printunit.h"
class MyPrintUnit : public GPrintUnit
{
public:
MyPrintUnit() {;}
virtual ~MyPrintUnit() {;}
virtual void DefineColHeadings(){}
virtual void CreatePrintFonts(){}
void InitPrintMetrics() {}
virtual BOOL Print(){return 1;}
CFont m_fontHeading;
CFont m_fontBody;
CFont m_fontHeader;
CFont m_fontFooter;
};
...
MyPrintUnit unit;
unit.Print();

I download some article about shell programming and try to run it.
After that it always run although I restart my PC and can't delete this DLL files too.
Please give me some idea for solve this problem.

Read the article. The DLL is probably registered with COM, so unregister it.

That mean can't stop it, right?

Shell extension are used by shell, so if it is registered, then you need to unregister it.

Hi
Does anyone know how to do exception handling in constructor?
|
|
|
|

try and catch block aren't enough for you?
