My guess is that you have a control on the dialog that's probably not installed on the target machine.

Alpha windows problem, need help!
I had download the code from:
http://www.codeproject.com/gdi/pxalphablend.asp

I've put controls on the dummy dialog. I can press a button on the dialog, just can't see it. Can anyone direct me to some help on how to make any controls appear on this dialog?

My OS is Win2000
VC 6

Moving a CStatic control

LittleYellowBird17-Mar-03 4:31

I've created a CStatic control in my View window like this:-

CRect rect (m_rectGraph.left, m_rectGraph.bottom, m_xChar * 6, yChar);<br />
m_wndLevel1Static.Create(_T("???"), WS_CHILD|WS_VISIBLE|SS_LEFT, rect,this);<br />

Now I need to move it to another area in the View window. I've tried SetWindowPos and MoveWindow but I can't be using them right because either it will not compile or it aborts when I run it.

Am I using the wrong function, or can any one offer a quick example?

Thanks for any help,

Ali

MoveWindow should work fine.. Are you trying to move it before it gets created? Maybe post your move code..

Transparent bitmap with CImageList

Hi everybody, help me

Why the following code draws a black color instead a transparent color

hBitmap - handle of a bitmap
crTransparent - a transparent color

            CSize sz(0, 0);

int nRetValue;
BITMAP  csBitmapSize;

// Get bitmap size
nRetValue = ::GetObject(hBitmap, sizeof(csBitmapSize), &csBitmapSize);

sz.cx = (DWORD)csBitmapSize.bmWidth;
sz.cy = (DWORD)csBitmapSize.bmHeight;

CImageList img;
img.Create(sz.cx, sz.cy, ILC_COLORDDB | ILC_MASK, 1, 1);
img.Add(CBitmap::FromHandle(hBitmap), crTransparent);

HICON hIcon = img.ExtractIcon(0);
pDC->DrawState(pt, sz, hIcon, DSS_NORMAL, (CBrush*)NULL);

Best regards,
Eugene Pustovoyt

Hello,
It looks good to me, the only thing I can think of is maybe crTransparent doesn't equal the color your trying to make transparent..

In MSDN it says the following:

int Add( CBitmap* pbmImage, COLORREF crMask );

pbmImage
Pointer to the bitmap containing the image or images. The number of images is inferred from the width of the bitmap.

crMask
Color used to generate the mask. Each pixel of this color in the given bitmap is changed to black and the corresponding bit in the mask is set to one.

I usually set crMask equal to "RGB(255,0,255)" and make sure every pixel that I want to show transparent is RGB(255,0,255) in color..

Hope this helps..

Hello,
This is kind of a strange question.. When you have an app open or minimized you can see the button on the taskbar associated with the application.. Is there any way to change the title of the button on the task bar with out changing the title of the application??

This PC Mag utility[^] (with source code) may help you get at the items in the task bar. You should be able to rename the item without changing the title of the corresponding main window.

One solution is SetWindowsText().

SetWindowText();
ModifyStyle(WS_CAPTION, WS_SYSMENU, SWP_FRAMECHANGED);

Multiselect CFiledialog

ns17-Mar-03 3:35

I'm stepping through the list of filenames retrieved fron the filedialog using GetNextPathName and GetStartPos, and for some reason it starts with the last file I selected (I'm doing a shift - click to select multiple files). Is this the expected behavior? THe order of selection is important to my app so I am wondering why it si starting from the last file selected....?

Appreciate your help,
ns

The first filename returned is the one that had the focus rect in the list, which will be the last name you clicked on.

Prompt on window closing

I want to display a message box when the user closes the main view of a MDI framework, in order to let him know that every other view will be closed.

What method of the CScrollView derived class have I to ovveride?

Ive tried with OnDestroy, but I've seen that it's called after the window has been removed form the screen.
The OnClose method seems not to be called, as I've place a breakpoint in it.

Thanks!

I believe you need to handle OnCloseDocument() from with in the document not the view..

I don't think so, because I ant to check if I'm closing the main window, while other windows are still open. If I close the main view over a document, every other associated view must be closed.

Re: Prompt on window closing

When you say main window or view do you mean the whole application or just the active view in the application? I guess im not sure we are talking about the same thing.

Override CDocument::CanCloseFrame() and return TRUE/FALSE if it's ok/not ok to close the frame window.

Need help of CListCtrl with Up/Down keyboard

ATC17-Mar-03 2:48

ATC

17-Mar-03 2:48

Hi,

I using CListCtrl (VC++6.0) for a list of information, I do not have any problem to use the Mouse (or Right Click) to get information of a specific row ... by using:

<br />
int sel = m_browseW.GetNextItem (-1, LVNI_SELECTED);<br />

*) But when I use the Up/Down Keyboard (the 'highlite row' shift Up/DOWN) then I do not know which command I can try to read the new 'specific row'

Anyone can help?

Many thanks

Re: Need help of CListCtrl with Up/Down keyboard

Alvaro Mendez17-Mar-03 7:45

Loop through the list and check the state of each row:

for (int iItem = 0, nItemCount = m_browseW.GetItemCount(); iItem < nItemCount; iItem++)
{
	if (m_browseW.GetItemState(iItem, LVIS_SELECTED) & LVIS_SELECTED)
        {
                // This item is selected.
	}
}

Alvaro
