In Visual C++ editor menu; go to project->Insert Components and controls and choose to insert a Microsoft Webbrowser control. All you have to do now is create a variable for the web browser and you can access all the functionaliy of Microsof Internet Explorer 5. As easy as it gets...

You can use OleLoadPicturePath load the picture from a file, you'll get an IPicture then use the method Render to display it into a DC.
Or, check Dr. Yovav Gad's article CPicture - The Yovav (Horror) PictureShow

Changing data in arrays with variables

How would I change the data in a 6x5 char array in selected cells with a variable? i.e.

eeeeee
e
eee
e
eeeeee

How would I change the e's to g's and display the following?

gggggg
g
ggg
g
gggggg

Just change it via [] operator.

variable[][] = 'g';

Thanks Terry.

I had almost this code except I had a syntax error with a single "=" instead of "==" to test the character.

That is one of the most frustrating of bugs if you don't force yourself to remember that right off the start. It compiles and on many passes it even evaluates to the correct value.

Are there any Time functions available on this

Thanks(TIA), VBFingers.

Ahem.

Look at the top of the page. You see our green friend Bob, the Code Project mascot? Below him in the orange bar is the word Search: and to the right is an edit field. Type the word 'time' (quotes not required) and click on the Go button to the right.

Hi,
Windows has already a bunch of APIs for that purpose. Check this link

Was wondering how i would increase an integer in a c++ program for every second that passes by. Is this possible to do without making a connection to the windows systray timer? hopefully this could work in at most a few for loops Frown | :(

Hi,
Check the Platform SDK documentation, "Timer Functions"

Function                      Description 
KillTimer                     Destroys the specified timer. 
QueryPerformanceCounter       Retrieves the current value of the high-resolution performance counter. 
QueryPerformanceFrequency     Retrieves the frequency of the high-resolution performance counter. 
SetTimer                      Creates a timer with the specified time-out value. 
TimerProc                     An application-defined callback function that processes WM_TIMER messages.

So, create a TimerProc function where you can increase the variable by one, then use the SetTimer function to set the callback every 1000 milliseconds, that's it.

Another solution is a thread that increment the variable very time interval.

Monitoring CPU usage

Hi. Does anybody know how I could monitor CPU usage (in %) in my Win32 application. Kinda like the Windows XP/2000 task manager. I know of performance counters, but I'd like a portable solution (the app must run on Windows 98 too).
And one other thing, how do I check if a given process (by name or ID), is, in fact, a Windows XP/2000 service?

Does it matter? Even if it does matter, does it matter that it matters?

Converting an in-process Component to Out-of-Process

Hi, I was wondering on how difficult it is to convert a working in-process COM component (a dll) to an out of process COM component (an executable). The reason I am asking this is because I would like to move a dll to 64-bit while having the client in 32-bit. Due to the different architecture, they cannot run in the same process, so the only way to to this that I can think of is to have the server run as an out-of-process component. Any ideas? TIA.
