I used the SetCursor() function to change the cursor when the mouse pointer is on a button or on a notified picture,that I've been told, but there's something I'm doing wrong. Can anyone send me an example on how to do it???...Please in Win32 application..

I have been trying to do that for a while now too and I just figured it out, almost...I subclassed the windows/buttons where I want the cursor to be a different image and I process the WM_MOUSEMOVE message setting the cursor like so:

WM_MOUSEMOVE:

SetCursor(hCursor);

The only problem with this is that when I click on the button it changes into the arrow for a fraction of a second then back to a hand...that's the best I can do for now. If you do find something better than this (Win32 of course) please let me know I am also very curious...Email georgiek50@yahoo.com.

Call SetCursor(hCursor) in the WM_SETCUROSR message instead and that will alleviate this problem. WM_SETCURSOR gets called before every single mousemessage, whether it is mouse move, button click or whatever.

In your message window proc:

case WM_SETCURSOR:
{
    if (HTCLIENT == lParam)
    { 
        ::SetCursor(hCursor);
        return TRUE;
    }
}

This code will set the cursor when the cursor is in the client area of your window. It will still turn into the sizing arrows if your window contains the WS_THICKFRAME style for resizing. By returning true after you set the cursor, it prevents the default handler from setting the cursor to the arrow. If you would like to change any of the cursor for some other portion of the window, not just the client, you can see a list of HitTest codes in the WM_NCHITTEST message.

Good Luck

16-bit PCX loader

I've been working on a game using bitmap files, and now I'd like to change it to a smaller format in order to save a lot of disk space. Gif's and such won't do as it needs to be 16/24-bit images.

So I was thinking PCX. Now I just need to make a file loader. Problem is - I don't know anything about the PCX format. So, could anyone refer me to some reading material or source code?

Is there any other graphics format that would be better?

PCX is a nightmare. don't bother.

BMP has a 16-bit flavor and you can find the specs in MSDN.

Hi,

Wonder anyone can answer my Question. I need to create a directory with many sub-directories using c commands. Which command to use and if possible where to find to source code. THKS.....

CreateDirectory - Win32
mkdir (or maybe it's _mkdir) - Standard "C"

There is no API that works on all OSes, however SHCreateDirectoryEx() works on Me and 2K+ if that restriction is acceptable to you.

Haven't I answered you already. From what I remember I have given the symbol to use and the WIN32 API method to call. You haven't followed my answer by an acknowledgement of whether it did anything good for you. Which is already a BAD thing, let aside you didn't even thank.

Now this renewed post looks like an insult to me. Dead | X|

first of let me say that
i am very sorry for that.
a bundle of thanks for your previous help .

yes you told me the win32 api i know that.

[DllImport("advapi32.dll", CharSet=CharSet.Auto)]
public extern static IntPtr CreateService(IntPtr databaseHandle, string serviceName, string displayName, int access, int serviceType, int startType, int errorControl, string binaryPath, string loadOrderGroup, IntPtr pTagId, string dependencies, string servicesStartName, string password);

MY service has been created in csharp may i have to
re-create it in vc++ to do this ?
or it is possible with the existing service?
i am very much confused about this win32 api?
there are a number of perameters although i study the msdn?
but i am confused where i have to call it in my code existing code or i have to creat it again in vc++?

Hi,

I've to make an application that allows the user to write his own script(VB Script) and the application has execute that script does anybody has an idea of how to go about it. any ideas would be greatly appreciated.

Thanks & Regds,
Vijay.

Does it have to be vbscript ? Python provides an excellent interface for allowing users to enter their own script and running it within the app.

Does the script interact with the app, or just run on the machine ?

Why are you asking this on the C++ forum, having found out how to do it in C# ? Is it a bad enough problem to change languages over ?

In C++, you have some functions called ::isalpha and ::isalnum. If the first returns false and the second returns true, you have a number. These functions take a character, not a string. You need to use these functions to parse your strings, then use atoi on the strings that you've verified have only numbers, or built to have only numbers.
