Using a vector will not initialise the values in it, it simply gives you a dynamically sizing array. You still need to set the initial values for the variables in the struct you're storing in the vector.
How does the vector get set up ? Can you post some code ?

Here's the declaration:
std::vector<Monster> monsters;
And here's how I initialize it:
monsters.resize(f_monsters);<br />
monsters[f_monsters-1].Location = x-sub;<br />
monsters[f_monsters-1].VerticalLocation = x-sub / width;<br />
monsters[f_monsters-1].SteppingChar.Attributes = c_black;<br />
monsters[f_monsters-1].SteppingChar.Char.AsciiChar = ' ';
Am I doing something wrong? Thanks!

How is this initialising anything ? You shouldn't have to call resize. Where do you call push_back ?

This sets up one object, the last in the list. What about the rest of them ?

push_back is how you add things to a vector.
Monster m;
m.strength = 100;
//etc
monsters.push_back(m);

Oh... alright!
But something still seems uninitialized... even though I initialize everything in the constructor, when I put a checkpoint in PaintMap(), the stuff still has weird numbers... Why is this? Thanks!

Hi there!
I'm trying to write somthing like this:
template <typename T> class tVar {
public:
virtual operator = ( T );
virtual operator = ( SomethingElse );
private:
T Data;
};
but a problem as arrised here. I'd like SomethingElse to also be a template so I could do:
tVar<SomeType> MyVar;
MyVar<SomeOtherType> = ( SomeOtherType )SomeOtherVar;
Can this be done? If not, i would apreciate some suggestions 
Thx!
Peace [[]]

Of course it can be done. If it could not, then the standard template library (STL) would not work. But it depends on what the template class does and what requirements are placed on the on arguments to the template.
Examples:
vector<vector<int> >; // space between > and > required
vector<string>; // string is defined as basicstring<char>
INTP
Every thing is relative...

I have a shortcut defined as
%windir%\SYSTEM32\RUNDLL32.EXE "d:\Omega16 xxx\g32csg.dll,FONTMANAGERDIALOG"
rundll32 does not give me any error nor does it execute g32csg.dll. If I change it to
%windir%\SYSTEM32\RUNDLL32.EXE "d:\Omega16\g32csg.dll,FONTMANAGERDIALOG"
with no space in the Omega16 part of the name and also change the actual folder name it works. Any path with spaces doesn't seem to work. This has to be simple but I'm missing it
This is on a W2K system. rundll32 version is 5.0.2134.1
Thanks in advance

What about:
%windir%\SYSTEM32\RUNDLL32.EXE "d:\Omega16 xxx\g32csg.dll",FONTMANAGERDIALOG

That seems to work as long as the "Start In" field points to the same folder "d:\Omega16 xxx"

Hi,
I am placing a bitmap on a button using LoadBitMap and SetBitMap.
The problem is that when I draw the bitmap, I want the background to be transparent so it will appear nice on the button.
From some reason, the "Draw Opaque" is checked by default in VisualStudio on the "Image" menu and I can't change it.
How do I use a transparent background on a bit map I am drawing.

Im having problems with a scroll bar issue. I have 3 scroll bars in a dialog, and i added a OnVScroll() method to my code to do some resricting of the scroll bars at certain times. But the problem is i only get 0's back.
void CScanPatternDlg::OnVScroll( UINT nSBCode, UINT nPos, CScrollBar *pScrollBar )<br />
{<br />
int low, high, curPos;<br />
CSliderCtrl* slider = (CSliderCtrl*)pScrollBar;<br />
<br />
<br />
slider->GetScrollRange( SB_VERT, &low, &high );
high = slider->GetScrollLimit(SB_VERT);
<br />
<br />
switch( nSBCode )...
also nPos = 0, which is supposivly the current position of the scroll bar. Also when i call getPos() on pScrollBar, it returns 0. I've fiddled around a little bit, and noticed that pScrollBar is equal to the HWND of the right scroll bar, so i guess i dont get why these methods arent working.. Any ideas?

greetings,
1. Is a CSliderCtrl kinda a CScrollBar?
2. Do child controls of a dialog window reflect messages to the parent window?
3. Can class wizard connect the CSliderCtrl messages to the parent window?

I wrote a simple program that cycles through a bunch a bitmaps and displays them each for 5 seconds. The program can run for hours. The problem is that the i can't stop the program once it starts (beside hitting the X and crashing). While inside the for loop, the menu is ignored. I'm sure this is common and there's a simple way to check for user input but I can't find it.

put the loop into it own thread... this way, it doesn't block the UI...

then in the loop (that's in its own thread), have it check some static variable or something that gets set to true when a certain button is pressed. Then add that variable as part of the criteria for your loop to continue looping

Greetings,
you have to allow the message pump of the main window run; Either dispatch messages from your bitmap loop; check msdn for pumpmessage;

Thanks a lot everyone. I'm wasn't ready to try tackling threads yet, especially for this program, since I just needed to cancel out of the main loop. I looked up info on PumpMessage() and found a great article call "Lengthy Operations Without Multiple Threads". I implemented the technique and the program runs exactly like I wanted it to.

How do I catch this even without checking if the point belongs to list box area or not ?
Please help.

Hi dudes!
I have an especial electronical device that I connect to my computer through USB, and there's a USB-serial driver that emule the RS232 communication through USB.
That's ok.
The fact is that many times I must to point to Control Panel -> Sistem -> Hardware -> Devices -> Comm Ports to see which comm port the device is using.
I want to developed an small application, with just a button. Then when I press it, a MessageBox shows the Comm Port used for that device.
What API function/s should use in the button click event handler to get that kind of information, (in fact, it is the same that control panel display in Comm Ports).
Thank very much guys!
Demian.

Well, you could enumerate the serial ports in the system, and then open/close them one by one. Any port in use will not open. Hence you will know which port is in use, but still, it could be a serial mouse. 
this is this.

you can read the regedit in you system,
"HKEY_LOCAL_MACHINE\\HARDWARE\\DEVICEMAP\\SERIALCOMM"
at there you can get the information you need!
