this is what is bugging me; I call DestroyWindow on my dialog, and it goes directly to the handle for the LBN_FOCUS even if there is no call to SetFocus; and the call stack goes from the function that calls DestroyWindow to the Handler for the LBN_FOCUS.
Are there other ways that a control can get/receive the focus ?
I will try to reduce the problem to something more manageable and get more info.
Thank.

That will be because it previously had the focus, and it is now losing the focus as it's destroyed.

Serge,
Thank you very much. So here is the big question:
Is there a way in C++ to append comments to methods and properties as there is in C#. I know that C++.net does not recognize the triple-slash, but I also saw something about Output Browser Information and was wondering if that was the mechanism for exposing method comments???!!

Michael,
MSDN states that “Visual C++ provides limited support for XML documentation comments”. I do not know what they mean by that (what is supported and what is not), but as per the .NET 2003, even if I want to attach a simple summary to a class, like this:
/// <summary>
/// This is my Visual C++ class
/// </summary>
class MyClass
{
};
Visual C++ would generate an empty Comment Web Page (via the “Tools | Build Comment Web Pages…” option). And the Visual C++ compiler does not support the /doc compiler option as the C# compiler does.
May be other people have something to say on this?

I have included code to try and draw a button with a different background when the button has been activated (pressed once).
I have a bool which tracks the state of the button.
HBRUSH CEmuGUI::OnCtlColor(CDC* pDC, CWnd* pWnd, UINT nCtlColor)
{
HBRUSH hbr = NULL;
CFont LabelFont;
if(nCtlColor == CTLCOLOR_BTN)
{
if((pWnd->GetDlgCtrlID() == IDC_1ST_BUTTON) && (g_bFirstButton))
{
LabelFont.CreateFont
(10,10,0,0,FW_BOLD, FALSE, FALSE, 0,
DEFAULT_CHARSET,OUT_CHARACTER_PRECIS,
CLIP_CHARACTER_PRECIS, DEFAULT_QUALITY,
DEFAULT_PITCH, NULL);
pWnd->SetFont (&LabelFont, TRUE);
pDC->SetBkColor(LTGRAY_BRUSH);
pDC->SetTextColor(RGB(255,255,0));
return (HBRUSH)GetStockObject(LTGRAY_BRUSH);
}
}
return hbr;
}
I am getting in a bit of a mess.
What I would like is when the button is pressed, background color is green and button text is bold and when pressed again revert back to normals colors.
Any suggestions.

I have a CListCtrl with some text. I have an add, edit and delete
button that functions according. Instead of delete a row, Id like
to just strikethrough the text that is displayed in that row. That
way, they can always undelete. Any ideas on how to make a row of
text in a CListCtrl look like it was striked out? I can change the
row color, but that just doesn't do it.
Please, any response any one can give me will be greatly
appreciated.
Sincerely,
Danielle Brina (an overworked graduate student)

The first thing that comes to my mind is: Get the bounding rectangle of the item (GetItemRect) or subitem (GetSubItemRect) you want to strikethrough and draw a line in the middle.

I want to draw a rectangle on a bitmap image that i have displayed on the client area by moving the mouse. It is like the selection that we do in mspaint. Can anyone please help?
|
|
|
|

Take a look at the CRectTracker class, which implements what you need.
If you vote me down, my score will only get lower
|
|
|
|
|
Thank You Roger Allen for the prompt reply. I have implemented it and is working well. But how do i get the selection rectangle remain there after i release the mouse button.
|
|
|
|
|
Rather than using CRectTracker, just use the function DrawFocusRect. It does not go away until either the area is repainted, or you call DrawFocusRect again to erase the rectangle.
onwards and upwards...

Hi everybody !
Can you tell me where I find resources(article,forum,sample,etc)about translation the application text to a different language ?
Thanks.

Hi all,
I'm trying to develop an application, that will get an avi file and preview the video, and, whenever needed, will write a part of video into one file (copy a clip from time x to y) and write corresponding audio data to separate file. Is there any other way to do this, than just building a preview graph and, whenever it's needed, adding (or maybe just linking/unlinking pins) some kind of splitter and two file writers? So I will be able to seek the stream? What filters I should use? I'd be very grateful for any tips..

I am using vfw and trying to allow the user to select the codec they want to use. After investigation I have found that some of the codecs on my machine are not valid for frame by frame rendering from a bitmap, ie MS H.263/261 ( appear to be for streaming compression ).
If I use AVISaveOptions, this lists all CODECS, but fails on AVIStreamSetFormat for some codecs as above.
If I use ICCompressorChoose, which takes a BITMAPINFOHEADER pointer and list those codecs that are valid for that type, I get a list of CODECS that work but this does not give me back enough info to setup the AVICOMPRESSOPTIONS for some of the codecs, I think this is to do with the lpFormat and lpParms parts.
How can I combine the limited list given by ICCompressorChoose and the AVICOMPRESSOPTIONS stuct populated by AVISaveOptions?

hiho@ll
1. i'm using a CStatic to move text left to right bounds of the static control
2. i can set the speed of the text movement through a float variable called n (move text n pixels)
my problem:
i'm using bitblt to copy the text (the whole area) to the screen
if the mouse cursor is above the static control i slow down text movement
if the movement is fast it dosen't flicker
but if the text movement is slow only the text begins to flicker!?
slow text movement is like, moving the text very few pixels in a direction during a bigger time interval (i mean like move it 0.3 pixels every 30 milliseconds)
i also looked at the article of Keith Rule lnk[^]
and maybe it's a problem with my eyes, but in Keith Rule's example the pixels flicker sometimes a little bit?
i think that's why my text flickers if it's too slow
what's interesting too, is that my background of the text which is a image doesn't flicker
i think because it's always the same, and the text changes it's position
anoyone knows a workaround?
hmm *thinking*
is there a way, to only draw the text, without overdraw it with the background to erase it?
i do:
1. draw background
2. draw text
3. bitblt
but programming a method which only erases the text will be too slow!?
thx@ll

I am using two dialogs derived from CFormView. These two
dialogs are mutually exclusive and I am unable to toggle between these two
dialogs at runtime. It would be nice if some one could tell me how to do it using menu options which can be checked or unchecked.
