In "OnInitDialog" ... it's the "farest" code after a dialog is initialized or?

Big thanks for your help Smile | :)

If you sleep inside your main thread, the GUI will be frozen because you don't process GUI messages anymore. That's also the reason why you don't see the two first texts. For this purpose, you should use a timer, this will be much better.

Transparent Control on Gradient Fill Dialog Box..

Hi all..

I've one Dialog box in which i fill the background color gradiently using this code...

void GradientFillRect(HDC hdc, LPRECT rcGradient, COLORREF start, COLORREF end, BOOL isVertical)
{
	BYTE startRed = GetRValue(start);
	BYTE startGreen = GetGValue(start);
	BYTE startBlue = GetBValue(start);

	BYTE endRed = GetRValue(end);
	BYTE endGreen = GetGValue(end);
	BYTE endBlue = GetBValue(end);

	HBRUSH endColor = CreateSolidBrush(end);
	FillRect(hdc, rcGradient, endColor);
	DeleteObject(endColor);

	//Gradient line width/height
	int dy = 1;

	int length = (isVertical ? rcGradient->bottom - rcGradient->top : rcGradient->right - rcGradient->left) - dy;

	for (int dn = 0; dn >= length; dn += dy)
	{
		BYTE currentRed = (BYTE)MulDiv(endRed-startRed, dn, length) + startRed;
		BYTE currentGreen = (BYTE)MulDiv(endGreen-startGreen, dn, length) + startGreen;
		BYTE currentBlue = (BYTE)MulDiv(endBlue-startBlue, dn, length) + startBlue;

		RECT currentRect = {0};
		if (isVertical)
		{
			currentRect.left = rcGradient->left;
			currentRect.top = rcGradient->top + dn;
			currentRect.right = currentRect.left + rcGradient->right - rcGradient->left;
			currentRect.bottom = currentRect.top + dy;
		}
		else
		{
			currentRect.left = rcGradient->left + dn;
			currentRect.top = rcGradient->top;
			currentRect.right = currentRect.left + dy;
			currentRect.bottom = currentRect.top + rcGradient->bottom - rcGradient->top;
		}

		HBRUSH currentColor = CreateSolidBrush(RGB(currentRed, currentGreen, currentBlue));
		FillRect(hdc, ¤tRect, currentColor);
		DeleteObject(currentColor);
	}
}

Now i've one picture box using for icon and one static box for some text. So how do i change picture boxes and static control background same as my current color(Gradient Color)..

Thanks all..

Static Box problem is gone..

case WM_CTLCOLORSTATIC:
{
	HBRUSH hbr;
	SetBkMode((HDC)wParam, TRANSPARENT);
	hbr=(HBRUSH)GetStockObject(NULL_BRUSH);
	return (LONG)hbr;
}

What message should i handle to make my picture box transparent?? In which i'm drawing icon???

Changed My code something like this..

case WM_CTLCOLORSTATIC:
{
        HDC hdc = (HDC) wParam;
        HWND hwndStatic = (HWND) lParam;
							
	HBRUSH hbrBkcolor = (HBRUSH)GetStockObject(NULL_BRUSH);
        if (hwndStatic == GetDlgItem(hWnd, IDC_ICON))
        {
	    SetBkMode ( hdc, TRANSPARENT );
	    return (LRESULT) hbrBkcolor;
        }
        if (hwndStatic == GetDlgItem(hWnd, IDC_TEXT1))
	{
	    SetBkMode(hdc, TRANSPARENT);
	    return (LRESULT) hbrBkcolor;
	}
	break;
}

But no success..What am i doing wrong??

Do you link to Wininet.lib?

Somethings seem HARD to do, until we know how to do them.

It is a compile error, I never link. I think during compile phase, import library is never used. Correct? Smile | :)

Actually, I have added Wininet.lib to Project --> Properties --> Linker --> Input --> Additional Dependencies. Is that the correct place?

George

Compiles fine here
MinGW 3.4.5

Have you tried including windows.h before wininet.h?

I've had errors similar to those before when including in the wrong order or
not including something explicitly (which in the end just affects include order)

Thanks, after including windows.h before wininet.h, the compile passed. So weird. Smile | :)

Here is the compile pass code.

#include <windows.h>
#include <wininet.h>

int main()
{
	InternetOpen ("Test Agent", INTERNET_OPEN_TYPE_PRECONFIG, NULL, NULL, 0);
	
	return 0;
}

George

Actually, there's nothing weird. To start with it, the first error message that you got was:

1>c:\program files\microsoft sdks\windows\v6.0a\include\wininet.h(58) : error C2146: syntax error : missing ';' before identifier 'HINTERNET'

When you open the error location, you find this:

typedef LPVOID HINTERNET;

So, the error clearly suggests that LPVOID is not being recognized as anything at all - a semicolon is expected there. If you try to locate the definition of LPVOID, it is within WinDef.h

But, WinDef.h is included in Windows.h - so, Windows.h must be included before wininet.h Smile | :)
