Further to your message, I'll restate the problem:
I am using a class CProgressDlg which is derived from CDialog. I am creating a modeless dialog in a generic class, so I use something like this:
CProgressDlg dlg;
dlg.Create(NULL);
where the Create function is as shown in the first email. This function throws an ASSERT failure. I think the problem is due to the fact that CDialog creates a dialog with parent wnd as AfxGetMainWnd() which returns a CMDIFrameWnd() as opposed to CMainFrame() in an SDI app. I have used this CProgressDlg class before in an SDI app and had no problems, and the only difference I can see is this.
Am I clearer now?

Sorry I misquoted the above, lpDialogTemplate is not NULL.
BOOL CWnd::CreateDlgIndirect(LPCDLGTEMPLATE lpDialogTemplate,
CWnd* pParentWnd, HINSTANCE hInst)
{
....
hWnd = ::CreateDialogIndirect(hInst, lpDialogTemplate,
pParentWnd->GetSafeHwnd(), AfxDlgProc); //CAUSES ASSERTION FAILURE
//pParentWnd is not NULL
...
}

Hi,
Firstly, yes it helps.
You see earlier I had this function called:
<br />
BOOL CProgressDlg::Create(CWnd* pParent)<br />
{<br />
CDialog::Create(CProgressDlg::IDD, pParent);<br />
}<br />
and this crashed when I did:
<br />
CProgressDlg* pDlg = new CProgressDlg();<br />
pDlg->Create(NULL);<br />
But now I got rid of Create function and added Create(IDD) in the constructor and it works. Do you know why?

Hi,
The user have an ability to change a Windows font size and type(Display Properties/Apperance/Font Size: Normal, Extra Large, Large), and those changes affect my application fonts, dialog boxes, some controls, etc...
I just need an advice, what the best way to handle it in the GUI.
And another question.
Can I some how to preserve my application's default font(MS Sans Serif size 8) from overriding by Windows?
Thanks.

Does anyone know which sytem colour is used for the background of the task pane shown on the left hand edge of Windows Explorer windows in XP?
Thanks

Not exactly. But you can use the Display applet's Appearance tab (rundll32 shell32.dll,Control_RunDLL desk.cpl,,2) in Control Panel and GetSysColor() to figure it out.

Yeah that's the funny thing... I can't figure it out. I don't think I'm being stupid, but I can't find where this colour comes from! I think it comes from the theme itself somehow, but I'm not sure!

Hello,
I am trying to build a download accelarator (a program which downloads a file through several connections to increase the speed).
I have created four threads. Each thread downloads the file from diffrent offset and finallly I join al this parts.
The problem is that when I use one thread( without changing the thread's code) it much faster. It like the additional threads are slowing one another.
In each thread I initialize the connection (CInternetSession->CHttpSession) and later in the thread I have put a loop which downloads the files.
The initialization part is in a critical section.
Can anyone tell whats wrong. Did anyone encountered similar problem?
Sincerely yours
Y.R.

how many CPUs does your computer have ?
( for that matter, how many internet connections does it have ? )

I have one cpu and one internet connection (750 k). But it should not matter because when one is downloading file from a server that is slow multiple http connections to this server will raise the overall speed like many existing download accelators(e.g. Get Right, DAP, etc..)
I think the problem is in my multithreading part.
Sincerely yours

When I look at the preview all works fine, but after printing there is a solid line on the paper.
What can I do?

Hi all,
I am doing a project for uni which basically get images from a logitech quickcam pro 4000 camera, and the guy in our group who compiled our current software has stopped doing the subject and left us with a server/client package that streams the video fine, but encodes using H.263 mpeg encryption not MJPEG and i have absolutely no idea how to convert from one to the other. I found the library used for encryption that he wrote/borrowed and i was wondering if i could email this library to someone, then they tell me which parts to change and i could post the parts that need changing so others can see it as well, as i know that is the policy here, there is just too much code to display in the one message. Any help would be appreciated as I have been left in the deep end here.
regards,
Jordan

Would it be of any benefit to look at the MJPEG format at www.wotsit.org[^]?

I had a look at witsit.org and it said the page is under construction so i couldnt get any MJPEG information from there. Are there any other sites where i can see sample code of MJPEG implementations?

I have found some code which is here: www.morgan-multimedia.com/downloads/codec.c and i was wondering if anyone can have a look at it and tell me how to implement the code like which function do what etc. It would help me a lot,

Hi all,
How am I going to change the given time to given time zone and get the converted time in string format?
let's say.
gmt = +06:30 and giving time dt is in different time zone
following function that I wrote is totally wrong. it is not giving me the correct time string in the given time zone.
CString convertTime(int gmt,COleDateTime dt)
{
COleDateTime formatedDateTime;
COleDateTimeSpan timeSpan(0,gmt,0,0);
formatedDateTime = dt + timeSpan;
dtStr = formatedDateTime.Format("%Y-%m-%d %H:%M:%S");
return dtStr;
}
Thank you so much for your help.

Have you seen any of the time-related functions:
localtime()
gmtime()
asctime()
LocalFileTimeToFileTime()
SystemTimeToTzSpecificLocalTime()
TzSpecificLocalTimeToSystemTime()
GetTimeFormat()

What is the value of gmt ? In your example, it cannot work, because in order to add 6:30 you will have to do the following:
COleDateTimeSpan timeSpan(0,6,30,0);
which cannot be achieved with
COleDateTimeSpan timeSpan(0,gmt,0,0);
Another solution:
transform gmt from an int into a COleDateTime, and do not use any COleDateTimeSpan but only COleDateTime.

Thank you David and Rage for your replies.
I look at gmtime() and it is seems like what I need to use. But dont' really know how to comvert COleDateTime dt to given gmt time.
here what I have..
CString converttime(CString gmt,COleDateTime dt)
{
//let's say gmt="+03:30" and dt = aug 25,2005 6:58pm
//the converted time should be dt3 = aug 26,2005 3:28 am
int hr,min;
CString hrStr,minStr, sign;
int pos = 2;
sign = gmt.GetAt(0);
minStr = gmt.Right(gmt.GetLength()- (pos+1));
hrStr = gmt.Left(pos);
hr = atoi(hrStr);
min = atoi(minStr);
COleDateTime dt2(0,0,0,hr,min,0);
COleDateTime dtDiff = dt+dt2;
}
I got it wrong again.. how can I convert it the given time to the given GMT time that has + and - time?
Thank you so much for your help.
