are you talking about .NET Windows Forms ?
if so, you're on the wrong forum.
but if using mfc, use the DoModal() function for instance. see an example[^]

For apply selected color use of WM_CTLCOLOR </code message and you need to a variable for hold return value that is COLORREF for use in the <code>SetBkColor .
-----------------------------------------
For show an intensity value of selected color GetRValue for red GetGValue for green GetBValue for blue .

Use the CoCreateGuid() or UuidCreate() APIs. If you need to avoid Win32 APIs, the algorithm for generating them is in RFC 4122[^].

Probably, you wanted to say CColorDialog[^].

I used the below coding
CColorDialog dlg(RGB(255, 0, 0), CC_FULLOPEN);
int retval = dlg.DoModal();
if(retval == IDOK)
// retrieve the chosen color
COLORREF color = dlg.GetColor();
but I want to display this color how can I implement it

Hi,
I have developed an installer for my MFC based application.
I create a new Environment variable at the time of installation.
But my MFC application is unable to access the new Environment variable unless I restart the computer.
Is there any way that I get the newly created Environment varialbe without restarting the computer?
Thanx.

After you make a new environemnt variable, you need to broadcast a WM_SETTINGCHANGE message.

Hello,
is there some event that can be registered for a new process that might start in the future?
So far I have a Thread that checks whether there is a new process running and then sleeps for some time.
I dislike using the sleep-function. I'd rather like to register some event for this.
Is there anything like that?
I hope I could make myself clear and I hope you have an answer?
Thank you for reading so far.
regards

Look up "Interprocess Synchronization" and "Synchronization Functions" in MSDN. I've never done this across processes...only interthread, but a quick glance at it suggests it is basically the same.
The concepts you'll be interested in are alertable waits, the function WaitForSingleObjectEx, and probably CreateEvent and SetEvent.
However, this requires that the other process participate in the syncronization and I'm not sure if that is precisely what you were after or if you require the other process your waiting on not have any knowledge or code committed to this syncronization. If that is the case, this will not likely help you much but I thought it worthwhile to put it out there, just in case.
I hope it helps.

Thank you bob16972,
I'm going to have a look at the topics you suggested. Maybe it will fit my needs.

Hey all,
My last [meaningful] programming experience was programming assembly on the 6502/6510 and the 6802 MPUs in the early eighties. I'm tending to relate the function of pointers in C++ to the role of the "Indexed Addressing Mode" in assembly (e.g. LDA $0400,X ), but there seems to be a significant layer of abstraction that I'm not grasping. I've never programmed in C or C++ or really any HLL since the 80's and I'm having tremendous difficulty with pointers.
I see a lot about how great and useful they are, but aside from the mundane examples, their real usefulness evades me. The examples likely containing *practical* examples are equally likely far beyond my C++ proficiency level. Given this relative impass, can someone explain in general terms what application might be aided by pointers? (Indeed, there must be some application in which pointers are absolutely necessary.)
Naturally, links to existing resources would be great as well.
I'm certain that relating pointers with indexed addressing is a significant fallacy, but right now it's all I have to work with.
Thanks,
fadibitz
If you see only one solution, then you don't understand the problem.
