VC++ 6.0 MDI programmatically create a new document

I am in the process of writing a very simple MDI application that uses CDAORecordset and CDAORecordView classes to talk to an Access Database. I have created 2 sets of derived classes CRequestSet, CRequestDoc, CRequestView, CContactSet, CContactDoc, and CContactView. I have created the Document templates for both documents and added them.

CMultiDocTemplate* pDocTemplate;
pDocTemplate = new CMultiDocTemplate( Confused | :confused:

IDR_REQUESTTYPE,
RUNTIME_CLASS(CRequestDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame
RUNTIME_CLASS(CRequestView));
AddDocTemplate(pDocTemplate);
pDocTemplate = new CMultiDocTemplate(
IDR_CONTACTTYPE,
RUNTIME_CLASS(CContactDoc),
RUNTIME_CLASS(CChildFrame), // custom MDI child frame for contact
RUNTIME_CLASS(CContactView));
AddDocTemplate(pDocTemplate);
I have also created the required additional resource files. I have found how to have the application start with no active documents, and how to not have the popup display when I select new from the menu.

I have added new menu entrys in the IDR_MAINFRAME menu resource IDD_ACTION_NEWREQUEST, and IDD_ACTION_NEWCONTACT. What is the code necessary to have the application create a new CContactDoc document when the IDD_ACTION_NEWCONTACT is clicked, and a new CRequestDoc document when the IDD_ACTION_NEWREQUEST is clicked.

I am a newbie so any background information and explaination will be greatly appreciated.

Thanks,

Clint

I think you have to keep pointers to your CMultiDocTemplate objects in your application class. Then when you need new empty document, simply call:

pDocTemplateRequest->OpenDocumentFile(NULL);
or
pDocTemplateContact->OpenDocumentFile(NULL);

I hope this helps.

Will this work for multiple Document templates, and if so how?

Hey all,
I want to display set of values in the listbox in my project.

How do I do to diplsy the values with proper spaces between them so that the "=" is spaced equally on all the lines. this makes it more easier to read.
say: like this:

fruit = 5
tomatoes = 6

Thanks in advance.

My suggestion is to use List ctrl instead of Listbox so that the item can be displayed in two columns.

Add a list control from the toolbox.
Create control variable of the list control and then use InsertItem etc to create columns of the list control in the OnInitDialog()......

Somethings seem HARD to do, until we know how to do them.

How to invoke a command in a context menu?

I am doing secondary programming on a CAD software with its API, and need to execute the command in the context menu of the CAD software programmatically, just like I manully right click a item and select a command.

I don't have any clue to do that now, and if it takes too many words to explain, could you please recommend me some material to read.

Thank you very much!!!

You have to chk that in the CAD api itself to see whether they provide such an extendebility.

Oh, it turned out to be NO, which is also why I ask question here.

Because there is no corresponding API, I hoped I could execute the command in the context menu in program to do the same thing as the user dose in interactive environment.

Thank you very much!!!

If the API doesn'tprovide such a functionality, then it is impossible for a user code to inject into another applications binary ( though it is possible to some extent through api hooking and ijecting code, its not that practical).

Question about the Ethernet Physical Layer

Hi,

I'm currently working on an embedded system which has an ethernet port and a TCP/IP stack running. I'm having some problems with a telnet TCP connection. I find that sometimes if I really hammer the TCP session with very regular commands the TCP connection seems to lock up because the PC fails to recieve an ACK packet thus halting data flow. Currently I'm using Etherial (a network packet sniffer application) to look at the packets the PC is sending and recieving, and it claims that my embedded system is failing to send an ACK packet occasionally, but I can't find any evidence of this in the embedded system. Is it possible that a packet that has been corrupted on the data layer, would be discarded before even showing up in ethereal?

Simple things first - try changing the network cable.
This could be caused by a poor connection affecting the magnetics - remember there is no such thing as ditigal electronics merely badly distorted analogue!
