Hi,,
I think the problem is in the code 
Y + 1.403 * V<br />
Y - 0.344 * U - 0.714 * V<br />
Y + 1.770 * U (do you write a jpeg decoder/encoder?)
you use U (an int) and Y (an int) so te hole equation uses ints which means loss of accuracy (int truncates what comes after the period)
so when you use Y (float) the compiler does not truncate them...

it's for CxImage
you'are right, but 1.403 is not an integer, so the * operator should give a floating point result, while in this case the result seems an integer. 
in fact, another way to fix the problem is writing the constants with the "f" suffix: 1.403f and the routine works

AfxMessageBox(strMaya);<br />
<br />
}

Here this represents a callback object
hr = m_pReader->Open(wszFullUrl , this, NULL );
if ( SUCCEEDED( hr ) )
{
//WaitForSingleObject( m_hOpenEvent, INFINITE );
_tprintf( _T( "successfull to open (hr=0x%08x)\n"), hr );
hr = m_hrOpen;
}
if ( NS_E_NO_STREAM == hr )
{
_tprintf( _T( "Waiting for transmission to begin...\n") );
//WaitForSingleObject( m_hOpenEvent, INFINITE );
hr = m_hrOpen;

Hi All,
I am trying to use a gradient control in my mfc app. And for that I downloaded the code from this website
http://www.codeproject.com/miscctrl/gradientprogressctrl.asp
I am using the GradientProgressCtrl.cpp class to implement in my mfc program. NOw one question is, since I am using the vertical control, how am I supposed to show the filling from BOTTOM TO TOP. The sample code shows the filling from top to bottom. I have looked into the code but nothing happened .
MY xyz.cpp uses it in the foll way where m_progbar is the instantiation of GradientProgressCtrl class. m_progbar is declared in xyz.h file.
m_Progbar.ShowPercent(TRUE);
m_Progbar.SetStep(20);
m_Progbar.StepIt();
My problem is that, after completion of 100 in the bar ctrl. I have to restart the app as filling of the bar stops after it completes the filling of the control.
I have triied lookin in the code but no use
Can you please help me with this.??
Thank a lot!!!

This isn't really a programming question I'm just wondering if visual safesource comes with either Visual Studio 6 or Visual Studio.net or both.
thanks you for your help
|
|

|

It's called Visual SourceSafe 
It comes with VS .NET Enterprise Edition (and VS6 Enterprise Edition), and you can get it as a stand-alone product.

Try #define WINVER 0x0500 in stdafx.h
SHGetFolderLocation needs shell32.dll version 5.0, and needs Win ME or 2K, or newer, to run...

Hello
I have a CRichEditView based MDI application.
I would like to know how to access the GetRichEditCtrl() and its functions (such as ReplaceSel) when I'm in another class such as MainFrm
What I want to do, in short:
A non-modal Dialog box (using the Create and ShowWindow functions) to be accessible by both classes MainFrm and CHTMLEditorView (my rich edit view class)
Thanks a lot

>I would like to know how to access the GetRichEditCtrl() and its functions

Following three statements give you your view from anywhere...
CMDIFrameWnd *pFrame = (CMDIFrameWnd *)AfxGetApp()->m_pMainWnd;
CMDIChildWnd *pChild = (CMDIChildWnd *) pFrame->GetActiveFrame();
CRichEditView *pView = (CRichEditView *) pChild->GetActiveView();
Obviously if you are calling from MDI you can use
CMDIChildWnd *pChild = (CMDIChildWnd *) GetActiveFrame();
CRichEditView *pView = (CRichEditView *) pChild->GetActiveView();
or simply
CRichEditView *pWnd = (CRichEditView *)MDIGetActive()->GetActiveView();

Hello
I would like to know who to add a line counter to the project. You know those gray bar to the left with line numbers which we can find in almost all those HTML editors.
Thanks for your help

Do you mean something to count the number of lines of code in your project, or a component to count the number of lines in some sort of edit control that is inside your application?

I am currently downloading a file from the web and checking info from it.
CStdioFile *remotefile;
CInternetSession mysession;
remotefile = mysession.OpenURL
(csUrl,1,INTERNET_FLAG_TRANSFER_BINARY|INTERNET_FLAG_RELOAD);
if(!remotefile)
return 0;
My question is can i write to the file that i just opened and save it back on the web server.
If this doesn't work is there another method if i want to write to a file over the web?

I have used CFtpConnection::PutFile(..) fn for that. But might also look a t CInternetFile::Write(..)

I'm doing some bencmarks on low-level high-priority threads, and I'd like to see how they do when some other process is hogging a large percenbtage of CPU resources - 80% or 90%.
Does anyone know of a utility that will suck CPU time through a straw?
Thx

search for cpustres,exe, it's installed with Visual Studio.
It does exactly what you want.

My question is:
Can I get info automatically on (all) functions that are in my project?
Here is what I want to do. I have a big workspace with several projects. I want to find all uses of a certain variable in each and every project. For example, I want to find every case that I use SYSTEMTIME or CTime in all my projects.
Can Studio report information in tabular format such as:
Function Name <--> Return Type
Function Name <--> File
Function Name <--> Class
Function Name <--> Project
Function Name <--> Argument List <--> Example of use
Return Type <--> Argument List
File <--> Project
Class <--> Project
You probably see what direction I'm going with this. I want to create a database that gives me info on my uses of a variable in an entire workspace.
Is this automated somewhere? I also have SourceSafe at my disposal. Sorry if this has been answered somewhere before, but I am not sure how to word my question or search.
Thank you
