if you want to get the Icon from some other window and use that in your window program you can use ExtractIcon api

here is small code listing for that

HICON m_hRemoteIcon;
CString m_strFileName;
<font color=#008000>//Assume m_strFileName point to valid Program file//Now use the Extract Icon api to Extract the Icon
//First Parameter =NULL( indicateuse the curent instance)
//Second Parameter = Name of file from which you want to extract icon
//Third Parameter : Index of icon ,here i am extracting the
// first icon from the exefile
</font>

m_hRemoteIcon=ExtractIcon(NULL,m_strFileName,0);
<font color=#008000>//here  m_statIcon is static ctrl of type ICON </font>
m_statIcon.SetIcon(m_hRemoteIcon);

Basicly in your propertysheet's OnSize handler you have to resize the tab control to match the sheet and then resize the active page to match the tab control. Then use your propertypage's OnSize handler to resize the controls on the page.

With GDI+ it could be like this:

#include <windows.h>
#include <gdiplus.h>
#include <stdio.h>
using namespace Gdiplus;

INT main()
{
GdiplusStartupInput gdiplusStartupInput;
ULONG_PTR gdiplusToken;
GdiplusStartup(&gdiplusToken, &gdiplusStartupInput, NULL);

Image* image = new Image(L"Crayons.jpg");
UINT imageHeight = image->GetHeight();
printf("The height of the image is %u.\n", imageHeight);

delete image;
GdiplusShutdown(gdiplusToken);
return 0;
}

Overriding mouse events in Win32 Console application

Hi,

Well, I have a console based application which keeps printing to the console for every second or so. The problem that I am facing is when some user clicks on the console, the application is just hanging because of the "printf()" function. The thread resumes operation only after the user presses the right click button.

Any clues as to how I can over ride the mouse events in a console application? (this seems to be the only solution to me, any other solutions are more than welcome).

I have heard something about "GetConsoleWindow()" etc. which provides an alternative to printf()...any1 can please update me on this??

Thanks a lot folks.

Regards,
Mahadevan.

Page Flip Effect

Hi!
I am writing an application kinda photo album in which i want to provide the page flip effect. i don't know what

should i select from the following:
DirectX
GDI
OpenGL
or something else.

currently i worked with my graphics+web designer and developed the application using Flash; but you might know that

flash is not reliable and doesn't provide better integration with VC.

I can code in VC, C# and VB/VB.NET. so i would appreciate your effort if you suggest me in this regard.

Thanks.

Hi,

Hi,

If you plan to write code in .NET, you can use GDI+.

GDI is most apropriate for this. Although you can use DirectX and OpenGL even if you are going to be using C#.

Hi!

I have source codes of my programs. One of them is dialog based application and the other is SDI Single Document Interface. I would like to combine that two sources into one. SDI program should have the dialog based program inside. What should I do?

Best regards.

CSdiApp
CSdiDoc
CSdiView
CSdiMainFrame
----------------
CDialogApp
CDialogDlg
---------------
now copy the clas CDialogDlg to the SDI app, you must also open
the .rc file from the dialog app and add the dialogtemplate to your SDI app

CSdiApp
CSdiDoc
CSdiView
CSdiMainFrame
CDialogDlg

now you must check the CDialogApp class, if there is some code you must
also add to your new App.

Add a menuentrie to the Mainmenu, and in the eventhandler for
this menu you can create a modal dialog of your
old app and show it to the user...

I hope this helps.

1.I don’t know how to copy the calss CDialogDlg to the SDI app. I tried using Insert->New Class but I get that message:

CDialogDlg.cpp is not a member of the current project.

2. I don’t know how to add the dialogtemplate do my SDI app.

Any suggestions?

Can't help with MSXML but I think you'll find articles here on CP if you do a search. Another option is to use pugXml, also here on CP which you may find easier.

You failed to mention what part of the code was in error? It's doubtful you will get much help, if at all, by posting a bunch of code, most of which is irrelevant, and asking folks to look at it and find the problem. You need to have gone through it and narrowed the problem down to just a few lines of code and ask for help with those.

If you are going to use MFC, there is no need to use char, FindFirstFile(), strtok(), etc. That's not to say it won't work, but it makes no sense to bounce back and forth between the two unless you need something that MFC does/can not provide.
