I am developing a service for a client, and must display a system-modal message box from the service. I would like my message box to look similar to other notifications displayed by the system (e.g. low power notifications, Windows Update notifications, etc.)
I can display an message box from the service in the standard Windows format. Is there an API to display windows in this format, or must I write it myself? 
Thanks.

There is no System Modal anymore, so you will have to find some other way of doing what you want. Take a look at Security Blackout Window[^] which may be of use, or provide ideas.

Thanks, this looks like what I need.

When I search on the Internet, I find millions of web pages explaining how to check if a .exe-file is running, from within a .bat-file. However, I can't find a single page explaining what to do if you have several .exe-files with identical names and you only want to check an .exe-file that resides in a specific folder. Can anybody please help me, what's the way to detect if the file C:\MyProject\bin\release\MyApplication.exe is running, but at the same time completely ignore C:\MyProject\bin\debug\MyApplication.exe?

I want to do it in bat-file language (the language you type in the command prompt C:\Windows\System32\cmd.exe)

Greetings to everyone. On my Windows 10 PC, I use Avast AV for an extra layer of protection on Windows Defender. But with the installation of Avast AV, the Avast Secure browser was installed. I don't really use it, so if I uninstall Avast Secure Browser, will it cause any problems with Avast AV on my PC? Please, give me some suggestions about this. Any kind of reply would be greatly appreciated.

In playing around with some basic GDI stuff, I had the need to draw an object in the middle of the main window and then when a button is clicked, draw that object progressively closer to some corner (in my code below, the object moves to the lower right corner, but ultimately I'd like it to move to any corner). So my question is: how to calculate those new X/Y coordinates with each button click?
The initial X/Y coordinates are calculated in response to WM_SIZE like:
case WM_SIZE:
nScreenWidth = LOWORD(lParam);
nScreenHeight = HIWORD(lParam);
nX = (nScreenWidth - nObjectWidth) / 2;
nY = (nScreenHeight - nObjectHeight) / 2;
break;When the button is clicked, new X/Y coordinates are "calculated" like:
case WM_COMMAND:
if (LOWORD(wParam) == ID_BUTTON)
{
nX += 20;
nY += 10;
InvalidateRect(hWnd, NULL, TRUE);
}
break;The object is drawn in response to WM_PAINT like:
case WM_PAINT:
{
PAINTSTRUCT ps;
HDC hdc = BeginPaint(hWnd, &ps);
EndPaint(hWnd, &ps);
}
break;You can count on one hand how many GDI projects I've done in the past (and have fingers left over) so I'm walking in somewhat uncharted territory for me. As a visual aide, if you envision a straight line drawn from the middle of the screen to one of its corners, each pixel of that line is on an X/Y coordinate. What would that calculation look like?
Thank you.

I don't think it is a straightforward calculation as you would need to move more pixels in the horizontal direction than the vertical (assuming landscape view). If you use GDI+ it is slightly easier as you can use float values for the points and Windows does the smoothing. But I am not 100% clear as to the actual problem. And incidentally, as far as handling messages and repainting, your code all looks correct.

I started reading about Bresenham's line drawing algorithm last night but haven't had time yet to put anything in place.

Here is a very simple method of moving the box:
You need to start by calculating the value of the slope ratio between horizontal and vertical size of the Window's client area. You need this as a floating point value as it will be used to calculate positions further on.
Declare a static float value named slopeRatio, and add the following code to either the initialisation (e.g. WM_CREATE), or whenever the Window is resized (WM_SIZE).
RECT rcClient;
GetClientRect(hWnd, &rcClient);
float horiz = (float)rcClient.right; float vert = (float)rcClient.bottom; slopeRatio = horiz / vert;
Then when you need to calculate the new X and Y positions of your drawing (after the button press) do the following:
currentX += 30; tempY = (float)currentX / slopeRatio;
currentY = (int)tempY;
InvalidateRect(hWnd, nullptr, TRUE);

so, i was doing some programming with eclipse and stuff. But then i noticed that all of my .JAR files suddenly looked like a pinguin with some painting stuff on his hands. i need help, cause im not sure what is going on!! I use windows.
[SOLVED] I had to right click a JAR file, and "press open in application" then select Java JDK. For some reason i had two of those...

I'm debugging the client's DHСP code on winsock and after receiving DHCPACK I want to check the received IP for a conflict. But I don't know how to. Could someone help with example?

That would probably depend on what you mean by "conflict"?
