Use a checklist box. See CCheckListBox.

I have a dialog application that contains OnSize() to handle the resizing messages. I have a Window containing an activex control. When resizing the Window, the ActiveX Control fills the entire dialog Window. I dont want to fill the entire Window. Does anyone know how to control the sizing of the activex control??

Hi everyone.
I'm coding a source filter and a demultiplexer filter for DirectShow.
When I add the filters to the graph, connect the pins and render the whole thing it still works.
But when I run the graph via IMediaControl::Run it returns S_FALSE.
The SDK says that I should use IMediaControl::GetState after Run() has failed, but GetState() does never return when I have INFINITE as timeout, else it returns an error (VFW_S_STATE_INTERMEDIATE), too.
The graph uses Push-Mode.
Is there a way I can find out what is going wrong?
Thanks for advice,
Alex

Problem solved. It's a live source, so there are some things different from a normal pull source.

What is the rigth method to add a Statusbar to a Dialog?
I had done this way.
CStatusBar m_StatusBar //Memeber variable
m_StatusBar->Create(this);
But whenever i call 'Invalidate' method the status bar also flickering
Is the GetClientRect retrieves the StatusBar area also?
Thanks in Advance

I think the status bar is flickering because it is a child of the dialog. If you invalidate the entire dialog, then the status bar comes along for the ride.
Some things I would try:
1. Invalidate only the specific client area of the dialog that does not include the status bar.
2. Adjust the client rect of your dialog to exclude the status bar.
3. Set the clip children style of the dialog, so it does not erase or repaint the area with the status bar or any other child controls.

Anyone knows a method which does hexadecimal to decimal conversion in the visual c++ library ??
Cheers

Now I've checked it. Here it is:
int hexToInt(const char * hex)
{
// Expects to get ONE hex digit at the time
int result;
sscanf(hex, "%x", &result);
return result;
}
int main(int argc, char* argv[])
{
int i = hexToInt("FF"); // i becomes 255
i = hexToInt("80"); // i becomes 128
i = hexToInt("40"); // i becomes 64
i = hexToInt("0"); // i becomes 0
return 0;
}

thanx for the reply, i will test your suggestion and see the results.
I am trying to get colours from the html source code and convert them to RGB format.
using your method will make it easy to convert a string of the format #ffffff
as i will just devide the string into three parts where each part represents red, green, blue respectively.
My problem now is that people sometimes do not use conventional formats but instead use for example : #fff to refer to #0f0f0f, that should not be so hard to deal with. a more complicated case would be : #9999 !!! how do i now which part of the string refers to red, green, and blue !!!

If you can format the string into a string containing 2+2+2 hex characters all the time, then you can use this way to get the values all at once:
int r,g,b;
// Create a test string:
char hex2[10];
strcpy(hex2, "0f05ff");
sscanf(hex2, "%02x%02x%02x", &r, &g, &b);
// Result: r == 15, g == 5, b == 255
It's tested and works.

I have tested #999 and i found that IE treats it as #090909
Which is bad news for me

not really.
6 hex digits : ok.
3 digits : ok (#fff = #0f0f0f)
anything else : add zeros to the right side to make 6 digits
word : use a map to find the RGB value

do you mean hexa into a string ? or hexa into an integer ?
if you want to cast an integer stored in hexa to a decimal, there"s no need to cas, because the hexadecimal is just a representation...

All i want to do is to convert colour formats to RGB decimal representation
for example: convert #ff0000 to be (255,0,0)
more complicated cases is when i encounter colours expressed as: #999
or #3333
how do you know which part is red, green, and blue !!!

#999 = #000999
#3333 = #003333
Isn't it?
Don't try it, just do it!

#999 = #090909 not #000999 (which are totally different)
#3333 can be #003333 or #033303 or #330303 or ...
you get my point !!!

So it is impossible to translate to decimal ! You cannot guess what the user wanted to have !! It is purely impossible without some strict rules.

When I type #999 in any graphics software I get #000999...!

If you stick with the numeric rules, there is no confusion
#3333 = 3333h = 0x3333 = 0x003333.
A good way to test this is if you type in the numeral in you calculator and see how it parses the input. leading zeros are implied and therefore not displayed.

split the hex number up in respective RGB values
0x112233 -> 0x11 is red 0x22is green 0x33 is blue
with some bitwise shifting the individual values are easily extracted.
COLORREF nRGBVal = 0x112233;
BYTE nRed = 0xFF&(nRGBVal>>16);
BYTE nGreen = 0xFF&(nRGBVal>>8);
BYTE nBlue = 0xFF&nRGBVal;
That should do it I guess..

Use GetRValue(), GetGValue(), and GetBValue() for this.
