I promised a company I would program a small application (using win32/mfc/vc++) that would put their logo in the top, right corner of every document printed (no matter from which application). I thought this would be an easy task Big Grin | :-D

, but...

I've spent hours on the net and can't find any information even touching the subject of editing already queued print jobs OMG | :OMG:

Please help me... Cry | :((

I have this strange problem: i am importing ExitWindowsEx function from the user32.dll file to shut down and restart computer. When i start my application from Visual Studio it works just fine but when i start it directly nothing happens. Blush | :O

( Note that Log Off feature works without any problems, and it uses the same function, only with a different parameter, of course. What is happening with my application ???

Changing the browsable attribute of a property at run time

Hi,

Is it possible to conditionally change the value of the "Browsable"
attribute at the top of the property constructor at runtime in VC++.net?
For example, I would like to conditionally change the following property
(PartNumber) to display in a property grid. I can control whether it
displays by inserting either Browsable(True) or Browsable(False), but I
would like to do this programmatically based on a condition.

[Browsable(True)]
__property String* get_PartNumber()
{
return _partNumber;
}

__property void set_PartNumber(String* value)
{
_partNumber = value;
}

thanks,
Pradeep

Get MDI Child Handle

Is there a way to properly get the handle of an MDI child window thats been added. I am creating a new form then making it a child of my parent MDI form:

<br />
mFrmSubWindow->MdiParent = this;<br />

Then I'm trying to get the windows handle, I do this by calling a fuction which does:

<br />
(HWND)this->Handle.ToInt32()<br />

When I call this I get an exception with the error "Error creating window handle" perhaps I am going about this the wrong way or not doing it properly?

Thanks!

Hello,

I have Windows Forms application (VS .NET 2003) where I need to draw several lines directly on some Form. How can I prevent those lines to be erased by overlapped window? What type of private member in this Form class do I need to use to store picture and use it inside “OnPaint(PaintEventArgs* e)” method to redraw this Form properly?

Thanks a lot for help, regards,
Leon

ERROR, to parse a parameter of a constructor from a pointer to a void

Hello

I´m working with a Genetic Algorithm library (GALIB), written in C. I know for sure that it works perfectly in VC++6.

Still I've got a problem:
I've got an error from one of the constructors defined in the library, and my question is:
ISN'T IT POSSIBLE TO PARSE A PARAMETER OF A CONSTRUCTOR FROM A POINTER TO A VOID?

I wrote the following lines:

class GAParameter
{
public:
GAParameter(char *fn, int tp, void *v); // line 32
~GAParameter(void);
};

The error:
GAParameter.h(32): error C2629: 'GAParameter (' unexpected
GAParameter.h(32): error C2238: token unexpected before ';'

PS: when I don’t write “void *v” there is no error, but I need this pointer!, and I can't discover what causes the problem.

THANKS A LOT

Difference between "->" and "."

I have some experience programming in C# .NET but am new to C++. Could somebody please tell me what the difference between "->" and "." are in C++, which is to say:

when is it appropriate to use

someclass.whatever

and when is it correct to use

someclass->whatever.

Thanks!

"ptrsomeclass->whatever" is shorthand for "(*ptrsomeclass).whatever"

you must have a pointer to someclass to use ->

you must have a direct instance of someclass to use .

for example:

someclass someobject;
someclass* ptrobject = &someobject; //&=addressof
someobject.whatever;
(*ptrobject).whatever; //* dereferences address
ptrobject->whatever; // same as line above

which contains a form

that contains a table with a field

and a button
SearchFrom the main page I want to simulate entering text in the editbox and clicking the button

VisStudio2003 Code Editor Screwed UP

mailsink8-Aug-04 16:33

Greetings All -
Looks like i got myself into trouble when I tried to remove an empty event placed into visual studio 2003, VC++, .net project.

I tried removing an event for a button, but couldn't figure out how to do it. So I manually deleted the generated event, and removed the code in InitializeComponent() for the event i didn't want - i then noticed the comment about do not edit stuff in this method.

Well as a result the editor is all screwed up.

For example - i compile the program, and it reports an error on line 200 - when the real line is actually 60 lines below. I also drop a button on the form and double click to generate a click event, and the editor places me about 50 lines above the generated event.

Is there a way to re-sync the editor? Or do i just have to remake my form in a new project?

Any help would be much appreciated.
Thanks,
CurtC.

Managed C++ Running Delay

We've just started doing a couple MC++ projects at work using VS .NET 2003 everything for the most part seems to be great but all of us have noticed a huge delay when running the program in visual studio (Hitting F5). This delay does not occur when double clicking the program and running it. Anyone know if there is a way to fix this?

Re: Managed C++ Running Delay

When you hit f5 your are running the debugger. Hit ctrl+f5 (runs without the debbuger) and it should be a lot faster.

Yipeee... just had a play making Visual Studio 6 IDE pick up the new Visual C++ Express compiler and tried compiling this simple app using the new C++/CLI and straight away it worked. Smile | :)

<br />
#using <System.Windows.Forms.dll><br />
#using <System.dll><br />
#using <System.Drawing.dll><br />
<br />
using namespace System;<br />
using namespace System::Windows::Forms;<br />
<br />
public ref class SimpleHelloWorld : public Form <br />
{<br />
public:<br />
	SimpleHelloWorld()<br />
	{<br />
		Text = "Hello, World.";<br />
	}<br />
};<br />
<br />
int main()<br />
{<br />
	Application::Run(gcnew SimpleHelloWorld);<br />
}<br />

No intelisense though (as you'd expect)

Managed C++ is when you tell your VC++ compiler to output .NET code instead of native code Wink | ;)

Managed C++ runs in a virtual machine (very similar to the way java runs) and thus will most likely run slower than native code most of the time but it will provide better security and it also has built-in features that C++ does not have. A garbage collector is one of these features.

IL is compiled to native code before it
is executed. It is not like java byte code
that is interpreted.
