Hey. I'm making a program in Windows API in C++ (not MFC). I'm trying to add picture files onto buttons, or just on the form and when you click them, it processes an event.
Any help on how to load a .gif or any picture file onto a form or button? Thanks =)

You can use GDI+ to load a gif. You can use ::LoadImage to load a bmp from disk or resources. Then make the button owner drawn, and draw the bitmap onto it using the WM_DRAWITEM message. You can use an STL map to map the windows HWND to a bitmap to avoid global data, or better yet, wrap your buttons in a class and map the HWND to the pointer to the class instance.

Is there any way to mimic the behavior of PrintInsideRect() when printing from a CScrollView?
Printing... what a pain.
|
|
|
|
|
Yes, do the printing yourself 
Catch OnPrint in your derive CScrollView.

Any guidance on how to tell programatically whether Visual C++ is running? The simplest solution would appear to be if there is a known mutex that I could refer to, but I have had no luck finding any such information in MSDN or on the web.
Failing that, other suggestions also welcome. It's with a view to writing installer(s) using Martijn Laan's "My Inno Setup Extensions", so I can write an extension DLL in C++ if necessary.
Cheers,

You need to Use PSAPI Functions.
Start with ProcessEnum Function...
I wrote a class that Do that you need...
If you want for a ![Beer | [beer]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/beer.gif) I can share the class with you....

Also you can See what Applications Are running enumming the HWND...
Also I Wrote a Class that Do that....
The Principal difference is that for PSAPI functions you need the psapi.dll that is only in NT and W2K, Don't work under win 95/98. I don't Know what happens with XP..

There are two simple ways:
1. Enumerating processes. You can use the following classes to enumarate processes on both NT/2000 and Win9x. http://www.codeproject.com/threads/enumprocess.asp
2. You can use FindWindow API to find Visual C++ window. You can also give the class name as a parameter to be sure that the window found is Visual C++ Window.
Hope this helps.

Suppose I have a process's handle, how can I figure it's CPU usage?
(Same about it's memory usage)

For NT 4.0/2000/XP sistems, seems like GetProcessTimes was written thinking of you 
As for memory usage, the function to go is GetProcessMemoryInfo (implemented as part of the PSAPI performance Monitoring SDK).

Sorry for the ignorence, but suppose I called GetProcessTimes() and converted the FILETIME arg' to SYSTEMTIME (using FileTimeToSystemTime(),
how do I compute (and which parameter is the significant) the CPU usage of a process per second?
truthfully yours, Me.

SYSTEMTIME is not a good choice to calculate relative times.
To compute CPU usage per second, just call GetProcessTimes every second and compute the difference of the paramaters lpKernelTime (time spent inside system routines) and lpUserTime (time spent inside user code). To subtract two FILETIMEs, copy them to ULARGE_INTEGERs and subtract these (more info about FILETIME arithmetic on the online documentation about FILETIME).

I am working on an MFC MDI application. I'd like to have the document title (in the app's title bar) display an asterisk at the end when the document has been changed. When the document is saved, the asterisk disappears. MS Visual Studio's text editor has this capability.
Any suggestions on how to add this capability?

With AfxGetMainWnd you can get The main window Handle then you can use GetWindowText for read the Title and add a Asterisk when the docuement is changed using SetWindowText for write the new title. But Warning you can fill the Title with several asterisks, you need a control like a variable for this...

CDocument provides some methods to maintain the "changed and unsaved" state, namely IsModified and SetModifiedFlag. I guess the best solution is to override SetModifiedFlag (assuming your app is using this method consistently) and change there the document's title accordingly using SetTitle.

Uh, i've tried a few dozen times to write a function that sees if a certain item of a list is also in another list but it just wouldn't work. And there's also a second difficulty, but i'll explain by giving the information needed:
First of all, its not really a list, but its several strings i can get after eachother. I have to parse a line of text wich uses '#' as a seperator like this:
cookoo#woowoo#blabla#weewee
this is the string(mystring) and i parse it with AfxExtractSubString(...) like this:
int index=0;
while(AfxExtractSubString(Item, LPCTSTR(mystring), index++, '#')
{
if(Item!="")
// Item is a good string so...
}
}
This is the same way for the two lists/strings only that the second string/list contains less or as much substrings as the first string/list and the strings the second string/list contains are always in the first one. BUT! it is possible that certain string(s) in the second one have '[' in front of it and ']' behind like this:
weewee#[woowoo]#gaga#blabla
i need to see this and make a difference between strings that have [] and strings that dont.
So the main goal is to see if any items from the first string/list are in the second one and if they have [] or not.
Can anyone help me with this as my brain seems to lack stamina for this.

Try something like this:
int index=0;
int index2;
CString mystring;
CString csSecondString;
while(AfxExtractSubString(Item, LPCTSTR(mystring), index++, '#')
{
if(Item!="")
{
int n = csSecondString.Find(Item);
if (n > -1)
{
if (n>0)
{
if (csSecondString[n-1] == "[" &&
csSecondString[n+Item.GetLength()] == "]")
{
}
}
}
}
}
Hope this helps,
Bill

I was browsing the internet when i came across a free utility that enables you to make your pc accessible using a static name, such as www.123-321.com, and wondered if anyone knew how to make that.

Using any user-selectable domain name? Now that would be impressive...

maybe they have a pre-registered list of say around 500 domains

Besides, 500 domain names would go quick...!
