Hello,
I'd like my app to have 1 document and 3 concurrent views. These views must also be shown and hidden at the users' discretions, and they're to be in separate child windows. I've searched the articles and the internet but only found discussions about splitters and flipping between views one at a time.
Can anyone point me in the right direction?
thanks,
JennyP

It's been awhile since I did this, but this can be accomplished using an MDI interface. The first step is to match all your documents, child frame, and view classes together. This is done in your apps InitInstance function
CMultiDocTemplate* pDocTemplate = new CMultiDocTemplate(
IDR_MY_TYPE_ONE,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyView1));
AddDocTemplate(pDocTemplate);
pDocTemplate = new CMultiDocTemplate (
IDR_MY_TYPE_TWO,
RUNTIME_CLASS(CMyDoc),
RUNTIME_CLASS(CChildFrame),
RUNTIME_CLASS(CMyView2));
AddDocTemplate(pDocTemplate);
CMainFrame* pMainFrame = new CMainFrame;
The IDR_MY_TYPE_ONE and IDR_MY_TYPE_TWO are the resource defines for the string table strings that that name your templates.
IDR_MY_TYPE_ONE "\nTypeOne\n"
IDR_MY_TYPE_TWO "\nTypeTwo\n" The string after the first newline (\n) is used to name the document template.
You then have to override CMainFrame::OnFileNew() so that it uses the proper template
void CMainFrame::OnFileNew()
{
CDocTemplate *pTemplate = GetTemplate(_T("TypeTwo"));
if (pTemplate)
pTemplate->OpenDocumentFile(NULL);
}In CMainFrame::OnFileOpen you would pass the file name to OpenDocumentFile().
To open a new view of an already open document, you have to add the menu message handlers to your document class
void CMyDoc::OnNewViewTypeOne()
{
CDocTemplate *pDocTemplate = GetTemplate(_T("TypeOne"));
if (pDocTemplate)
{
CFrameWnd *pFrame = pDocTemplate->CreateNewFrame(this, NULL);
if (pFrame)
pFrame->InitialUpdateFrame(this, TRUE);
}
}
Here is the code for GetTemplate
CDocTemplate *GetTemplate (CString str)
{
CString strDoc;
CDocTemplate *pTemplate = NULL;
bool templatefound = false;
POSITION pos = AfxGetApp()->m_pDocManager->GetFirstDocTemplatePosition();
while (pos)
{
pTemplate = (CDocTemplate *)AfxGetApp()->m_pDocManager->GetNextDocTemplate(pos);
pTemplate->GetDocString(strDoc, CDocTemplate::docName);
if (strDoc == str)
{
templatefound = true;
break;
}
}
if (!templatefound)
{
TRACE (_T("GetTemplate() failed, Template not found"));
return NULL;
}
return pTemplate;
}There may be bits I am missing, but this should get you started.

Thanks for the help.
When implementing this code, my application runs, but upon startup, it pops-up an MFC dialog titled "New" which contains my two views and expects me to pick either one. If I hit cancel, no document is loaded; else, the app behaves correctly. How do I default a view (instead of asking the user to choose), and how do I show both views simultaneously?
thanks!

In your app's InitInstance function, there is a call to ProcessShellCommand. Remove that line. You then have to process the command line yourself. Look up CommandLineInfo in MSDN for all the possible options.
For example, if your user opens your app by double clicking on one of your associated files in explorer
if (cmdInfo.m_nShellCommand == CommandLineInfo::FileOpen)
{
CDocTemplate *pTemplate = GetTemplate(_T("TypeOne"));
if (pTemplate)
pTemplate->OpenDocumentFile(cmdInfo.m_strFileName);
}

Hello,
Thanks for the help. Just to make sure your solution matches my needs: I would like to have several views operate/interact with the same open document data set simultaneously. Is this the case here? I'm a little suspicious because perhaps MFC is asking about which document (data set) to open upon startup?
Also, is there an easier way to simply display the same document data in separate child windows rather than creating templates? I'm not complaining about the implementation, but in the back of my head, I'm thinking that manually starting and maintaining a child view would be pretty straight-forward. I would just have the added task of manually messaging this new window to update itself at the right times.
thanks,
JennyP

Yes.

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.

No, the templates are the core of the MFC Doc/View model

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.

CDialog::SetMenu() should do the trick.

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().
