while(nCount != nParticles)
should be
while(nCount < nParticles) //0 based indexes in C++

Ok, here is the situation. I have a CAxDialogImpl modal dialog created using a dialog I created. Let us call it CMyDialog. I set the caption in CMyDialog's resource editor. The dialog style is Overlapping and Resizing. Everything is right with the world. When the dialog is created via CAxDialogImpl<cmydialog>::DoModal, the caption in the resource is, predictably, displayed.
But now I want to change the caption of the dialog dynamically when the dialog is created ( It is instantiated from another dialog ). I modify the OnShowWindow function so that I may change the caption with SetWindowText(). Guess what; though the function returns success, the caption does not change.
I want to change the caption. SetWindowText isn't doing it. Anyone got any ideas? A grateful person awaits your learned replies.

Set the dialog's caption in OnInitDialog().

I discovered the problem; a previously overwritten WS_SETTEXT command. Thanks for the suggestion, though.

I want to include a background image in my programs about dialog, which is derived from CDHtmlDialog. Using the toolbar, I added the image and it inserted the following code:
This works fine on my computer but when I try the program on another computer it can't find the image since the path doesn't exist. I've tried using a relative path like but that doesn't work, even on my computer. VC doesn't seem to follow nornal HTML coding rules. Can someone please explain how to code this so the image will display properly on any computer?

You can put the image into your exe and use the res:// protocol in your body background tag.
onwards and upwards...
|
|
|
|
|
Can res:// be used to access a resource like a file in any application?

Thanks for the help. That took care of it.

hello,
I have a code that raise this error "Not enough storage is available to process this command." when I try to Realloc a buffer ....
temp = (DWORD)GlobalReAlloc((HGLOBAL)eyeConClients[msg - SOCKET_ID - 1].buffer, szTemp, GMEM_MOVEABLE);
this works ok many times ... and randomly raise that error ....
any suggestions ? please help ....
thanks !!!

GlobalRealloc() does not necessarily return the same memory handle as the one passed to it - it's value may change. You need to store the new value:
eyeConClients[msg - SOCKET_ID - 1].buffer = GlobalReAlloc((HGLOBAL)eyeConClients[msg - SOCKET_ID - 1].buffer, szTemp, GMEM_MOVEABLE); If you need to cast your buffer to a HGLOBAL, you will need to cast the return value of GlobalRealloc() to make it fit with your buffer variable. You didn't say what type it was, so I don't know what to cast it to - you'll need to do that.
Hope this helps,
Ryan

what is the value and datatype of szTemp?
What amount of physical memory available at the moment of the error?
What is the page file size?
What is the error number?

Hello. I have a problem. I want to make autoplay cdrom function disable in windows. I don't know how do it. Can you help me? Thanks
welcome to meet you!

you need to change value of registry key
HKEY_CURRENT_USER\Software\Microsoft\Windows\
CurrentVersion\Policies\explorer\NoDriveTypeAutorun
to (DWORD) 0x0FF disable
or (DWORD) 0x095 enable autoplay
|

Just to supplement what skaanji said...
For the NoDriveTypeAutorun variable, each bit in the value represents a type of drive. A bit set to '1' disables autorun for that drive type, '0' enables it.
Bit 0 = Unknown drive types
Bit 1 = Drives without a root directory
Bit 2 = Removeable drives (floppy, zip, jazz, etc.)
Bit 3 = Fixed drives (hard drives)
Bit 4 = Network drives
Bit 5 = CD/DVD drives
Bit 6 = RAM drives
Bit 7 = Reserved (always set to 0)
Hope this helps,
Ryan

Dear skaanji and Ryan Binns:
At first, Thanks a lot for you. You have said is correctly. But Because I have a little about register. So maybe it is difficult. Can you give me a example about it? I saw some about Enabling and Disabling AutoPlay articles in Microsoft MSDN. It's tittle is "Enabling and Disabling AutoPlay" . It seems that maybe have other method. Can you see the article for me. I am expecting...
welcome to meet you!

I don't think that there is any other way so you need to change the registry but this is what I use:
[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\CDRom]
"Autorun"="0" // 0 disable, 1 enable
I also agree with the other posts that suggest that you should not change user settings unless you let them know what you're doing.
// Afterall, I realized that even my comment lines have bugs

It is a VERY BAD IDEA to change people's registry. Look in MSDN for "disable autoplay" and it tells you a way to do it while your program is running without changing people's registry.

I'm going to patent thought. I have yet to see any prior art.

If this is your own computer I would change the registry however if this is a product you should not mess with the user settings in the registry unless you at least inform the user of what you are doing and allow them to cancel your change.

Hi, Sir:
I saw your answer about disable CDROM autoplay function . and I think so that It is a very bad idea to change people's registry. And I have sawn the "Enable and Disable AutoPlay" in MSDN. I do it that:
UINT g_uQueryCancelAutoPlay = 0;
BOOL DialogProc(HWND hwnd, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch (uMsg) {
...
default:
if (!g_uQueryCancelAutoPlay)
{
g_uQueryCancelAutoPlay = RegisterWindowMessage(TEXT("QueryCancelAutoPlay"));
}
if (uMsg == g_uQueryCancelAutoPlay)
{
SetWindowLong(hDlg, DWL_MSGRESULT, TRUE);
return 1;
}
}
}
but I can't success. Can you tell me How to do it? I wish to get your reply? Thanks
