Im using the following code to create and setup my pages
CMyPage MyPage
...
MyPage.Construct(IDD_MYPAGE_PROPERTY_PAGE);
...
AddPage(&MyPage);
Stated in the MSN docs, is that for another to work, the tab needs to be selected first, is there a way to bypass this option? Or a different way to construct the page so that it doesnt need to be clicked on?

Wow, that was quite the post. It has more information in it than many articles. It just may be worth it to take that post, add a working example, and post it as an article.

Thanks! Glad you liked. You know, making an article out of that post does sound like a good idea. I'll try to do it as soon as I finish a couple of things that are keeping me very busy these days.
Cheers,

Its definitly on the right track, but my situation is a little more unique. Im constantly getting real time data from a socket, and is needed to post the data all over my GUI, I guess I could create all the objects from all the pages and store them, like in your example, but seems like a lot of work, cause then when a tab is clicked, i need to override the clicktab button or something so that it adds it to the queue to be constantly updated.

Hi,
If the Application thread (receiving thread) is one of the thread involved in a message deadlock, how do we solve this issue. MSDN says we should call ReplyMessage, (if InSendMessage() returns TRUE), in the WndProc of receiving thread, before calling any of the yeilding function calls like DialogBox, GetMessage, etc. But since one of the thread involved in the deadlock is the application thread itself, GetMessage would have been called before it reaches WndProc. Can anyone please help me?
Thanks in advance,
Ajay

Hi, i'm trying to make an aplication to blend subtitles onto a video stream. The renderer i need to use is the Video Mixing Renderer 9. The application is based on one of the examples of the DirectX SDK, called Text9. I'm using parto of the code. I've build the filter graph, with the VMR-9 as renderer. When i try to add the bitmap to the VMR's input, the program says: "Unhandled exception in executable.exe:0xc0000005:Access Violation".
This is the code:
HRESULT CText::BlendText(TCHAR *szNewText)
{
LONG cx, cy;
HRESULT hr;
CSubtitlesDlg dialog;
// Read the default video size
// hr = pWC->GetNativeVideoSize(&cx, &cy, NULL, NULL);
// Create a device context compatible with the current window
HDC hdc= GetDC(dialog.GetSafeHwnd());
HDC hdcBmp = CreateCompatibleDC(hdc);
// Write with a known font by selecting it into our HDC
HFONT hOldFont = (HFONT) SelectObject(hdcBmp, g_hFont);
// Determine the length of the string, then determine the
// dimensions (in pixels) of the character string using the
// currently selected font. These dimensions are used to create
// a bitmap below.
int nLength, nTextBmpWidth, nTextBmpHeight;
SIZE sz={0};
nLength = (int) _tcslen(szNewText);
GetTextExtentPoint32(hdcBmp, szNewText, nLength, &sz);
nTextBmpHeight = sz.cy;
nTextBmpWidth = sz.cx;
// Create a new bitmap that is compatible with the current window
HBITMAP hbm = CreateCompatibleBitmap(hdc, nTextBmpWidth, nTextBmpHeight);
ReleaseDC(dialog.GetSafeHwnd(), hdc);
// Select our bitmap into the device context and save the old one
BITMAP bm;
HBITMAP hbmOld;
GetObject(hbm, sizeof(bm), &bm);
hbmOld = (HBITMAP)SelectObject(hdcBmp, hbm);
// Set initial bitmap settings
RECT rcText;
SetRect(&rcText, 0, 0, nTextBmpWidth, nTextBmpHeight);
SetBkColor(hdcBmp, RGB(255, 255, 255)); // Pure white background
SetTextColor(hdcBmp, g_rgbColors); // Write text with requested color
// Draw the requested text string onto the bitmap
TextOut(hdcBmp, 0, 0, szNewText, nLength);
// Configure the VMR's bitmap structure
VMR9AlphaBitmap bmpInfo;
ZeroMemory(&bmpInfo, sizeof(bmpInfo));
bmpInfo.dwFlags = VMRBITMAP_HDC;
bmpInfo.hdc = hdcBmp; // DC which has selected our bitmap
// Remember the width of this new bitmap
g_nImageWidth = bm.bmWidth;
// Save the ratio of the bitmap's width to the width of the video file.
// This value is used to reposition the bitmap in composition space.
g_fBitmapCompWidth = (float)g_nImageWidth / (float)cx;
// Display the bitmap in the bottom right corner.
// rSrc specifies the source rectangle in the GDI device context
// rDest specifies the destination rectangle in composition space (0.0f to 1.0f)
bmpInfo.rDest.left = 0.0f + X_EDGE_BUFFER;
bmpInfo.rDest.right = 1.0f - X_EDGE_BUFFER;
bmpInfo.rDest.top = (float)(cy - bm.bmHeight) / (float)cy - Y_EDGE_BUFFER;
bmpInfo.rDest.bottom = 1.0f - Y_EDGE_BUFFER;
bmpInfo.rSrc = rcText;
// Transparency value 1.0 is opaque, 0.0 is transparent.
bmpInfo.fAlpha = TRANSPARENCY_VALUE;
// Set the COLORREF so that the bitmap outline will be transparent
// SetColorRef(bmpInfo);
// Give the bitmap to the VMR for display
CFilterGraph Graph;
hr = Graph.m_pBMP->SetAlphaBitmap(&bmpInfo); <----This is the point where i get the problem.
// Select the initial objects back into our device context
DeleteObject(SelectObject(hdcBmp, hbmOld));
SelectObject(hdc, hOldFont);
// Clean up resources
DeleteObject(hbm);
DeleteDC(hdcBmp);
return hr;
}

Hi
We have a large app that we are converting to WinXP from Win2000. We would like our toolbars and dialogs (check boxex, radio buttons, push buttons etc) to have the WinXP look and feel (called a theme maybe?).
How can this be achived ? I have added a call to InitCommonControlsEx() at the start of our GUI thread, but the buttons still look the old way.
Any ideas on an easy way to get the WinXP look and feel ?
Thanks
Tim Cox

In the normal course of events, an application will automatically look like XP when run on that platform. Changing the code is not required. To verify this, create a small application using AppWizard and run it on both the Windows 2000 and Windows XP machines. They should both look correct.

The apps do look exactly the same on both Win2K and WinXP. That is my problem. I would like them to look different. In other words, I would like the app when running on WinXP to have the WinXP look and feel. Like buttons showing emphasis when the mouse hovers over the etc. How does one get buttons that show this type of emphasis ? (ie the border changes color to indicate that the mouse is over the button and that the button can be clicked?

It seems you may be using VC6 instead of VS200x. If so, you can get the XP look by adding a manifest to your app enable visual styles. See this[^] article, specifically the section "To create a manifest and enable your application to use visual styles.".
Here's[^] a screenshot of an app I created using VC6, running on an XP box.
Hope this helps!

I'm using VS2003 (7.1.3088), so that's not my problem.
What I would like is that the buttons in my app to show a colored emphasis when the mouse moves over them, like all the apps do on WinXP. Right now, they show nothing, just like they did in Win2000.
Other apps do this. Example is IE. On Win2k, the buttons are regular, but on WinXP, the buttons show a yellow/orange emphasis when I move my mouse over them. This is what I want for my app too.
Am I making any sence ?

You're right.
Contrary to what I said in my earlier post, I believe my suggestion applies to both VC6 and VC7.x generated apps. It worked for me and generated an app that displays XP-like controls on XP and non-XP-like controls on W2K.

I did not say they should look the same. I said they should look correct, meaning that it should look like Win2K on that machine (e.g., dialogs have four square corners, X button is gray), and it should look like WinXP on that machine (e.g., top corners of dialogs are round, X button is red, caption is taller).
Other than that, I'm not familiar with code that would cause their appearance to change (or stay the same).

database.ExecuteSQL(sSql);
database.Close();
Like this it is adding to excel.

Did you look at how ValuesString is being constructed? The cause of your ' problem is right there?

i did not get whatu are telling. actually all those values in the values string are text values. so them i have written as 'content' .
because in the sql sltatement they should be given as
insert into tablename values('text1','text2',number e.t.c);
so have used format('%s', variablevalue) for forming ValuesString .
just now have seen while trying to print into number fields it is giving normally but while printing text values , the value of the cell is shown as normally only but preceded by a ' symbol when double clicking on the cell.
after dblclk on cell the value is like '1234 for text,
copy cell contents and paste it elsewhere in note pad they appearing like:
ECMName MID_Hex
peninsula 5678

Since the single quote marks in each cell are for display purposes only (they tell Excel to treat the text exactly as you have entered it), and does not affect printing or pasting to other applications, is there any harm in leaving them there?

nothing harm just. just i was afraid if sbdy access the contents of that file along its original contents these quotes may also come and disturb. thats why. no other problems.
