Is there a WIN32 function that will tell me whether any modifier key is pressed?
The context is a mouse hook function that is only interested if one or more modifier keys (shift, ctrl, alt) is pressed. If no key is pressed it just passes the event to the next hook.
I know that GetKeyState() returns the state of a specified virtual key, and that GetKeyboardState() returns an array of states. But a function that just tells me if ANY modifier key is pressed would add less latency in cases (most of the time) when a key is not pressed.
Thanks for listening

What's wrong with GetAsyncKeyState()?

Thanks for the reply.
Like GetKeyState(), I think GetAsyncKeyState() just tells me about a single key. I would prefer a single function call that tells me whether any modifier has been pressed, thus saving several system calls in the hook context.

Hi all,
My situation is that I have to intercept a click on the print button on an IE print preview window. The project dictates that the Page Setup dialog should be opened first when Print is clicked.
My question is what is the best way to do this?
I have subclassed the window but the toolbar buttons are not separate windows so all I'm getting is a WM_LBUTTONDOWN message to the main window with the location of the click. I can of course stop this message getting through but knowing for sure when the right button has been hit is where I'm having a problem with this technique.
Is there a way of querying the window to find the rect and position of the print button? I'm unhappy about measuring it myself and hard coding in the value in case some system change invalidates the value I've come up with
Thanks for any ideas and help
Cheers
Tom

CFont dateFont, eventFont;
LOGFONT logFont;
GetLogFontStruct(logFont, 16, 0, pDC);
dateFont.CreateFontIndirect(&logFont);
GetLogFontStruct(logFont, 10, 0, pDC);
eventFont.CreateFontIndirect(&logFont);
void CCalendar::GetLogFontStruct(LOGFONT & logFont,int height,int width,
CDC * pDC, CString strFontName)
{
logFont.lfHeight = -MulDiv(height + 1, pDC->GetDeviceCaps(LOGPIXELSY), 72);
logFont.lfWidth = -MulDiv(width, pDC->GetDeviceCaps(LOGPIXELSX), 72);
logFont.lfEscapement = 0;
logFont.lfOrientation = 0;
logFont.lfWeight = FW_NORMAL;
logFont.lfItalic = 0;
logFont.lfUnderline = 0;
logFont.lfStrikeOut = 0;
logFont.lfCharSet = DEFAULT_CHARSET;
logFont.lfOutPrecision = OUT_DEVICE_PRECIS;
logFont.lfClipPrecision = CLIP_DEFAULT_PRECIS;
logFont.lfQuality = ANTIALIASED_QUALITY; //CLEARTYPE_QUALITY; //PROOF_QUALITY;
logFont.lfPitchAndFamily = 0; //DEFAULT_PITCH | FF_SWISS;
_tcscpy_s(logFont.lfFaceName, strFontName);
}
i do restore font after drawing
after this while drawing in case of dateFont it comes ANTIALIASES_QUALITY
but in case of eventFont it does not come...
plz help.

Use CxImage[^].

I already tried this using following code
but that image lost it's transparency and looks like bmp
HBITMAP m_bitmap = NULL;
CxImage image("myfile.png", CXIMAGE_FORMAT_PNG);
...
CDC* hdc = m_picture.GetDC();
HBITMAP m_bitmap = image.MakeBitmap(hdc->m_hDC);
HBITMAP hOldBmp = m_picture.SetBitmap(m_bitmap);
if (hOldBmp) DeleteObject(hOldBmp);
if (hdc->m_hDC) m_picture.ReleaseDC(hdc);
...
if (m_bitmap) DeleteObject(m_bitmap);

Ah, you won't get transparent blitting from the picture control (which is a CStatic actually), look at Stuart Dootson's post. You will have to do the blitting yourself, i recommend using CxImage's own blitting methods.

- Create a 'picture control' to hold the picture
- Derive a class from CStatic that'll draw the picture. It should declare a message map and handle WM_PAINT and use a CImage to hold the image. Note the call to
TransparentBlt, which (as I've coded it) assumes that the top-;peft pixel of hte image is the transparent colour:
class MyPic : public CStatic
{
public:
MyPic();
protected:
afx_msg void OnPaint();
DECLARE_MESSAGE_MAP()
private:
CImage image_;
};
MyPic::MyPic()
{
image_.Load(png filename);
}
void MyPic::OnPaint()
{
PAINTSTRUCT ps;
CDC * drawDC = BeginPaint(&ps);
CRect rcClient;
GetClientRect(&rcClient);
image_.TransparentBlt(*drawDC, rcClient, CRect(0, 0, image_.GetWidth(), image_.GetHeight()), image_.GetPixel(0, 0));
EndPaint(&ps);
} - Declare a member variable wfor the picture control that is of the type you've just made.
- See your picture be displayed!

Cimage is in VC6.0?
why because i am getting error

Probably not - but you didn't say you were using 10-11 year old software.
CImage is definitely in VS.NET 2003 - and that's the oldest VS I have.

CImage is just a wrapper around a GDI+ Image[^] - you could try using GDI+ - you will need to get a version of the Platform that a) is compatible with VS6, and b) contains GDI+.
As this Platform SDK[^] is the last one that works with VS6, I guess it's your best option.

Hi Guys,
I'm looking to be able to position 2 CToolBar objects into an SDI both permanently docked to the top but one left justified and one right justified on the same line. All my efforts so far leave the bars docked one above the other.
Any ideas?
Thanks

Hi,
I have created one sample application, which has one parent window. There i have created one picture frame, i want to insert one child window in the place of picture frame. I am able to do that and i am able to get vertical scroll bar on dialog box.
In child dialog i calling onpaint() for creating bitmap images and check boxes, there i want to create 20 bit map images, i did that.
Whenever i have scrolled down the scroll bar, the the image which is moving up is erasing, and it is displaiyng like overlapping all the images with one another...
Can any help me to get rid out of this problem..?
Thanks
Venkatesh.

You should really make a better post in order to get any help. For instance post the relevant code and be more detailed and precise about the error (i.e. aat what line it occurs?).

Try using smaller records (45s?) or switch to CDs like the rest of us
