Thanks for ur reply...
but how can i get the fixed border "b" or proportional border "bp"....
|
|
|
|

Well, suppose the text width is 120 pixels and the height is 20 pixels, then, a rectangle with a fixed, 5 pixels, border would have width = 120 + 2*5 = 130 pixels and height 20+2*5 = 30 pixels.
If you prefer a proportional border, say 5%, you may set width = 120*(100+5*2)/100 = 132 pixels and height = 20*(100+5*2) = 22 pixels.
If the Lord God Almighty had consulted me before embarking upon the Creation, I would have recommended something simpler.

Hi,
I am relatively new to working with Visual Studio/VC++. My requirement is to display an animation (AVI or AGIF) in a dialog control. This works fine. But what I also want is that when the dialog window screen is maximized, this animation (running in the dialog) should also resize/maximize accordingly. When the screen returns to normal position, the animation should also return to its normal size. Is is possible to do this? Right now, I'm only able to maximize the screen and not the animation (The animation is retaining its size). Please help!

You need to resize the control that play the animation manually; I assume when it resizes, it will resize the movie automagically.

I am able to resize the control. I have used EASYSIZE macro with the control's ID. So, the control is getting resized. But the animation still remains of the same size. (Is this what you mean by resizing manually or are there any other settings/changes?)

|

which control using to play AVI/AGIF?
If using CAnimateCtrl then ACS_CENTER is set?
u can use the below mentioned APIs for any control to resize.
use MoveWindow or SetWindowPos
to resize the control according to change in size of parent Window.

Yes, I have set ACS_CENTER and I have used SetWindowPos. This helps me resize the control. But the image being displayed on the control does not resize. I am not sure if resizing the 'image' is even possible.

Hi, I want to draw a Hindi text with a bounding box around. Sample text "मैं हिन्दी नहीं बोल सकता हूँ।".
The problem is the last character with dependent vowel sign, the method misses the bottom part of the text.
0x0939, 0x0942, 0x0901 (devanagari letter ha, vowel sign uu, sign candrabindu)
C# code sample
string text = "मैं हिन्दी नहीं बोल सकता हूँ।";
Font font = new Font("Tahoma", 20.0f, FontStyle.Regular);
SizeF layoutArea = new SizeF(1000, 1000);
StringFormat stringFormat = new StringFormat();
SizeF measure = g.MeasureString(text, font, layoutArea, stringFormat);
g.DrawRectangle(Pens.Red, new Rectangle(50, 50, (int)measure.Width, (int)measure.Height));
g.DrawString(text, font, Brushes.Black, 50, 50);
I have also tried C++ functions GetTextExtentPoint32(), GetTextMetrics() and GetOutlineTextMetrics() to get the correct height but failed.
Any suggestions?
Thanks in advance,
Gywox

|

Whats the output with GetTextMetrics API?
what is font height with that?
if is not correct then let me ask u whether u tried this given below:-
Hope u calculate it
height = Internal Leading + ( Point Size * LOGPIXELSY )/72
For more details please refer

1/ I suppose this is semi legitimate to post in this forum. C# has failed you, so you're coming to ask help from the grown ups?
2/ For a text bounding box, I alway use DrawText (...., DT_CALCRECT).
ie:
CString s = L"मैं हिन्दी नहीं बोल सकता हूँ।";
CRect rc;
DrawText (s, &rc, DT_CALCRECT);
rc should be 0,0,width,height.

as Iain said,
if it done with DrawText then we cannot find the font height with GettextMetrices.

Hello
How to GetHandle of Window from Resource ID in ATL COM
Thanks
ABM

CWnd* pWnd = GetWindow( RESOURCE_ID );
HWND hwnd = pWnd->m_hWnd;

In addiont to the other reply, if you have a parent window handle, and a window ID (which may or may not have anything to do with resources, but mostly does):
HWND hChild = ::GetDlgItem (hWndParent, nID);
Class win 32.

The project:
I wrote a program Ahook that hooks the keyboard and mouse events appear in the system and send them to other target application – the Paint which is not in focus and is in background window (i don't want it to be in focus and want it to be in the background). It means that I can for example move and use the mouse anywhere on the desktop or on any other application, but the Paint program will be operated as like the mouse was moving over it.
How it is done:
The Ahook uses the follow function to hook all keyboard and mouse events:
hHook=SetWindowsHookEx(WH_JOURNALRECORD,journalRecordProc, AhookInstance,0);
In order to send the messages to the Paint, the Ahook uses the follow function:
PostMessage(hPaintWnd, message,0, (iNy<<16) + iNx);
iNx and iNy are normalized mouse location values -means, I change the real location of the mouse to a location that is on the Paint program.
Results and problem:
I used the Spy++ to check the operation of all this and the Paint program receives all events Ahook sends. The location of the mouse as Paint sees is ok, means that paints "thinks" that the mouse is moving on it. But there is problem – the Paint program doesn't react to the events although it receives them. Why???
a) Is it because Paint is not in focus?
b) Is it because the messages found by WH_JOURNALRECORD hooked are not the relevant for sending to the Paint getmessage loop ?
c) Is there any other reason?
Some more information that may lead to conclusion:
a) Looking the Spy++ results for events Paint sees when Ahook sent it, shows very simple events such as WM_MOUSEMOVE and WM_LBUTTONDOWN etc.
b) Looking the Spy++ results for events received when mouse is used on the Paint, shows that the messages are much more complicated than just mouse move and mouse button down/up. It contains WM_NCHITTEST, WM_SETCURSOR, WM_NCMOUSEMOVE (but not WM_MOUSEMOVE) etc, is it says that what Ahook sends is not the relevant information???

Hope u hooked the window proc too WH_CALLWNDPROC
Величие не Бога может быть недооценена.

Why should I do it? why it may solve the problem?
In addition, can I hook with WH_CALLWNDPROC with non-dll application (Ahook is not a Dll) ?

Hi all,
I want to make a Data Stream.
I have used this code to make it. But using this code slows down my process.
IStream* pStream;
if(CreateStreamOnHGlobal(NULL, TRUE, &pStream) == S_OK)
{
ulWritten = 0;
pStream->Write(buffer1, 512, &ulWritten);
}
Can anybody please suggest the bug in this code or alternate code for doing this.
Thanks in advance

Well, all code slows things down. That's what doing stuff does.
You have to be careful to not do too much inside loops, etc. Classic programming stuff.
What might speed things up a little is if you know the size of data you'll be writing is to GlobalAlloc a chunk of memory, and feed that to CreateStreamOnHGlobal instead of it having to reallocate. But it's doubtful you'll get a great improvement.

Hello All~~
Does anyone know how to display the OpenCV image structure "IplImage" in MFC CView?
Typically, many example shows that after we called 'cvLoadImage()', it will call 'cvShowImage' to display the image in another seperate window (as the code below).
IplImage* img = cvLoadImage( argv[1] );
cvNamedWindow( "Example1", CV_WINDOW_AUTOSIZE );
cvShowImage( "Example1", img );
What if I would like to display the image readed by OpenCV 'cvLoadImage' into CView, how can I do that????
Any suggestion, please?????
Thank you very much.

Hi
I'm trying to submit a web form with method=POST parameter.
However, when I run the following code, I'm getting an error saying: "The URL is invalid"
CString strHeaders =_T("Content-Type: application/x-www-form-urlencoded");
CString strFormData = _T("query=murod&a=14");
CInternetSession* pSes=new CInternetSession();
CHttpConnection* pConnection =
pSes->GetHttpConnection(_T("http://www.wutever.com/"));
CHttpFile* pFile =
pConnection->OpenRequest(CHttpConnection::HTTP_VERB_POST,
_T("/news/"));
BOOL result = pFile->SendRequest(strHeaders,
(LPVOID)(LPCTSTR)strFormData, strFormData.GetLength());
What I'm doing wrong?
|
|
|
|
|
LOL I found my mistake 
CHttpConnection* pConnection =
pSes->GetHttpConnection(_T("http://www.wutever.com/"));
Looks like I should not include "http://" in the url.
Now another problem:
I'm able to send the request, but how do I get the response? The response will be a web page source?
After sending the request I wrote the content of the pFile(CHttpFile class) to a file and based on that file I'm guessing either I didn't send the request, or either I didn't get the response.
What should I do to get the response?
