Yes.

I'm a little suspicious because perhaps MFC is asking about which document (data set) to open upon startup?
No, MFC is asking which view to use to display the data. If you had multiple CDocument classes then the question would be which document, but AFAIK you have only one CDocument class.

is there an easier way to simply display the same document data in separate child windows rather than creating templates?
No, the templates are the core of the MFC Doc/View model

I would just have the added task of manually messaging this new window to update itself at the right times.
It's not all that difficult. As long as you remember that the document is the central part of your app. All your views do is display your data and pass any user input onto your document. Do not do any actual data manipulation in your CView classes, do it all in your CDocument classes. Whenever you do data manipulation, simply call UpdateAllViews and the MFC framework will update all the active views that are displaying data from the current document.

This will happen if you have more than one document template defined when the commandline parameters are processed. You can either: Define all the templates except one after the parameters are processed, or modify the parameter processing to prevent this behaviour. The defailt parameter processing calls OnFileNew() which shows the New dialog box if there are multiple document templates.

Hi,
I have included an MSFlexgrid control into my MFC application and I don't know if it is necessary to add the ocx file, as well as another files into the project to distribute the program (and what files?). And is it needed to make a registering routine for this Activex control in Windows register?
Thanks

I have visual c++ .net 2003 and am trying to add an MSchart to a form. I've selected it from the coms list and added it to the tool box. I then go to ad it to the form and get an AxImp.exe error message telling me it can't find AxInterop.OWC10.dll even though it's in the debug directory of the project. I have the same problem if I try using any other AxtiveX component, just a different dll in the error message.

I am using Microsoft Visual C++ 6.0. I ahve tried #include <stdlib> and #include <stdlib.h> and both are not accepted. Is their a header file associated with this function?
int pos = input.find(',');
while (pos != -1)
{
input.replace(pos, 1, "");
pos = input.find(',');
}
number = atoi(input.c_str());
cout << number << endl;
Thank You

Try using #include<algorithm>

I have used #include <stdlib.h and="" #include="" <stdlib=""> and it does not work with the following function.
int pos = input.find(',');
while (pos != -1)
{
input.replace(pos, 1, "");
pos = input.find(',');
}
number = atoi(input.c_str());
cout << number << endl;
Thanks

Hi!
In my app I've declared 2 dialogs via 2 classes. In dialog 1 I use a variable, that works well (of course..). Now I have to use the same var in dialog 2 (class 2) -> that won't work:
error C2597: illegal reference to data member
'CPIADlg::m_workdays' in a static member function
Has anybody the solution? Thanks, Thomas
PS: declaring as static ->
PIADlg.obj : error LNK2001: unresolved external symbol "public: static int CPIADlg::m_workdays" (?m_workdays@CPIADlg@@2HA)
Settings.obj : error LNK2001: unresolved external symbol "public: static int CPIADlg::m_workdays" (?m_workdays@CPIADlg@@2HA)
hmmm???

Hi everybody.
I need to open some files from my app. So I used do parse the register in order to obtain the default program and run it. For example, to open a pdf file I parsed the HKEY_CLASSES_ROOT for the ".pdf" key and got AcroExch.Document as value. Then I parsed again HKEY_CLASSES_ROOT for the "AcroExch.Document\shell\comman\open\" key and got the whole path of Acrobat Reader. Finally I opened the file using spawnl command.
With Acrobat it's almost all OK, but I neede to open html files too. And Internet Explorer doesn't work as Acrobat does, besides I got the right value of Ecplorer's path.
Any suggestion?
Is there any other way to open a file using its default program?
Thanks,

Use ShellExecute() or ShellExecuteEx().

Dim s As String, h As String, i As Integer
i = 1
s = ""
While i < Len(strtext)
h = Mid(strtext, i, 4)
i = i + 4
h = CLng("&H" & h)
h = ChrW(h)
s = s & h
Wend
Hex2Str = s
End Function
************************************************
for CLng i used atol
but for CHrW i do not know what i should use i tried different convertion but i am only gettin strang char

Maybe someone can help me on this: I'm creating a MFC custom control which is a combination of a CEdit and a CSpinButtonCtrl. The control is created solely by code, i.e. no resource editor.
The problem is that the edit control paints itself incorrectly. Let me explain:
1.) Directly after showing the dialog with the custom controls it looks this way (the control in question is the control labeled "Breite der Bilder"):
<a href="http://www.magerquark.de/data/misc/mfc-cedit-01.png">Screenshot 1</a> [<a target=_blank title='New Window' href="http://www.magerquark.de/data/misc/mfc-cedit-01.png">^</a>] As you can see, the border around the CEdit is missing and the text ("640") is hanging on the upper left border.
2.) If I move the mouse over the control it looks this way:
<a href="http://www.magerquark.de/data/misc/mfc-cedit-02.png">Screenshot 2</a> [<a href="http://www.magerquark.de/data/misc/mfc-cedit-02.png" target="_blank" title="New Window">^</a>] I.e. now it paints the border but the text is still in the upper left corner, now partially hidden by the border.
3.) The control resizes when the user sizes the dialog. Now when the size was change, suddenly it looks correct, as in this screenshot:
<a href="http://www.magerquark.de/data/misc/mfc-cedit-03.png">Screenshot 3</a> [<a href="http://www.magerquark.de/data/misc/mfc-cedit-03.png" target="_blank" title="New Window">^</a>] As you can see, now the "640" has 'snapped down' to the correct position (in contrast to the control labeled "Breite der Vorschaubilder", which doesn't scale). Also, the CEdit border now is always visible.
So something must happen upon scaling. I already examined the styles of the CEdit before and after scaling with Spy++ and also compared with CEdit controls created with the resource editor. The styles are always the same, so these are not the cause of the display-error.
Question: Can someone enlighten me about why this display-error occures an how I can get rid of it?
Thank you
Uwe

I do not know why the error occurs, but I have seen some controls appear one way and then readjust as if they have received a second invalidate rectangle command (or a resize command).
It occurs to me that when Chris Maunder designed the MFC grid control 2.25, he may have ran into that problem. So it might be worth looking at.
Good Luck!

I assume that the edit control is not a direct child of the dialog - it's a child of an intermediate container control. Can you tell if there are any messages (WM_NCPAINT comes to mind) that are being blocked by the container on initialisation, but are allowed to pass to the edit control later on.

I've seen something similar before... I forget exactly what I was doing, but a call to
control.SetWindowPos ( NULL, 0, 0, 0, 0,
SWP_NOMOVE|SWP_NOSIZE|SWP_NOZORDER|SWP_FRAMECHANGED );made the control redraw properly. (The SWP_FRAMECHANGED flag is the important part)

Tried that and some other methods, unfortunately without succeess. I already thought that the CEdit thinks it is "maximized" (without border) and when sizing it gets "restored" (with border).
I now examined with Spy++ and logged all messages that appear right before and right after the sizing.
These are the messages:
<a href="http://www.magerquark.de/data/misc/spy.png">Screenshot</a> [<a href="http://www.magerquark.de/data/misc/spy.png" target="_blank" title="New Window">^</a>] I now start investigating, maybe someone already has an idea which message causes the correct repaint.
