Caveats when using SetParent ? - C / C++ / MFC Discussion Boards

Thanks , but I should have explained better. What I needed to achieve was a way to cause my DLL to plug into an existing application by some other programmer, without having to involve the the other programmer .This way , he wouldn't have to change a bit. There would be only his application with a few MDI child windows created by him, while I hook up to those MDI child windows, I induce the creation of different toolbars for the respective MDI child and intercept all the messages to those windows, thus taking over the MDI children. I achieved it, everything works fine now. As I explained in the former posting, I do receive the rerouted messages. The WM_COMMAND message cannot be intercepted by me, it is intercepted in the MDI child, but I found a way around it. Whenever I create the toolbar, I keep record of the amount of buttons and record the rectangles within the toolbar, where they are located. Now, I need just to catch the WM_LBUTTONDOWN and ..BUTTONUP messages, thus enabling me to detect which button was pressed and take action... Works great !

Thank you for your interest !

The common logic is:

int nPos = str2.Find(str1);
int nDelLen = str1.GetLength();
if(nPos != -1)
str2.Delete(nPos,nDelLen);

This is a simple method. u can also use extraction method using Left, Right, Mid functions and concatenate the extract the string.

Or how about:

str2.Replace(str1,"");

Caveats when using SetParent ?

I have a CDialog (as child of something else) that I need to reparent to another window ( a CWnd child of a floating/non-floating evil dialogbar ).

Are there any caveats when reparenting CWnd in general ?

( I know it's very vague, but I'm looking for generics before going deeper into the problem )

Thanks.

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.

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#.
