Well, as I understood the documentation, you simply create a waitable timer to be waked at say 20 minutes, do the power down and windows should take care for the rest.

Hello,

I'm wondering if someone is familiar with the technique use by many programs today - starting the app before any other app, and pausing windows load (like adaware does).

Any help appreciated,

to load a program from another, use ShellExecute() (or more deprecated WinExec()).

to allow a program to be paused, you have to manage threads, with a flag raised by the GUI which is handled by the working thread...

No,

I know how to launch program, the effect that I'm after is loading my application at windows startup, process tasks, and then allow or shut down the system Smile | :)

Thanks

By "first" do you mean least significant or most significant? Check out the bit-related operators such as AND (&), OR (|), NOT (~), and XOR (^).

Hi,
I am developing a marker application. Basically allows free-hand drawing with the mouse. When i draw a line, i want the window below also to visible. I am not able to create a transparent Pen for this? i tried BS_HOLLOW, but it doesn't draw at all.

hdc = CreateDC(TEXT("DISPLAY"),NULL,NULL,NULL);
lb.lbColor = rgbCurrent;
lb.lbHatch = NULL;
lb.lbStyle = BS_SOLID;
//hNewPen = CreatePen(PS_SOLID,10,rgbCurrent);
//SetROP2(hdc,R2_MERGEPEN);
hNewPen = ExtCreatePen(PS_GEOMETRIC,10,&lb,0,NULL);
//SelectObject(hdc,CreateBrushIndirect(&lb));
//SetDCBrushColor(hdc,rgbCurrent);
SelectObject(hdc,hNewPen);
MoveToEx(hdc, PrevX, PrevY, NULL);
LineTo(hdc, CurrX, CurrY);
DeleteDC(hdc);
........

Can anyone help?

How to download secured web page ?

I need to download a web page but I prefer not to use CHttpView because I do not need to display anything.
The problem is that in order to get to the page I want I need to login using a form. Using CHttpView I traced the form and found that the information passed is like :
URL: https://url.com/page.asp
PostData: ui=user&pass=pass&other=other
Headers: Content-Type: application/x-www-form-urlencoded

But still, browsing directly to https://url.com/page.asp?ui=user&pass=pass&other=other didn't work.
Is there a way to do this ?

I also would like to keep the session/connection to download other web pages from the same site (using the same cookie or whatever)

Change color of controls of a dialog

Ward31-May-05 0:39

31-May-05 0:39

I can change the background colors of child controls of a dialog by responding to the WM_CTLCOLORxxx messages
Example:

case WM_CTLCOLORBTN:
hBrushButton = CreateSolidBrush(RGB(255,102,15));
return (int)hBrushButton;

Now I'm looking for a way to change the textcolor as well. This for buttons, labels, listboxes, ...

Thanks in advance,

Ward

That helped me.
Thanks!

My code is now the following:

case WM_CTLCOLORSTATIC:
hBrushButton = CreateSolidBrush(RGB(255,102,15));
SetTextColor((HDC) wParam, RGB(255,255,255));
SetBkColor((HDC) wParam, RGB(255,102,15));
return (int)hBrushButton;

This results is a nice orange label with white text. Smile | :)
