I have written a program that contains a CDocument derived class. The
user can create a document that is a template. Basically, the document
contains a list of objects like IMAGEBOXES, BORDERS, and CAPTIONS which
the user positioned on the document. This is all working fine. The user
can save and open the document.
Now, part 2. I have another application that needs to be able to open the
first program's document. However, rather than moving the document
objects around, this program needs to let the user specify what images go
in the IMAGEBOXES, what color the BORDERS should be, and what text should
go in the CAPTIONS. Also, this program does not modify the "template"
document. It needs to save a different document.
What is the logical way to implement this?
Should I just include the document class from the first program in the
second?
Can I just use the first program's document in the second program without
the view?
I do need the same basic view functionality in the second program (i.e.
drawing the IMAGEBOXES, BORDERS, and CAPTIONS. Should I use the first
program's view as well?
I don't know what my next step should be. Perhaps I should just write new
document and view classes that contain copy-and-paste pieces from the
original classes (but I want code changes for one to be reflected in the
other with the smallest chance of error).

What about creating a base document class with all the common code for each application, and then have derived classes for the different apps. Copy and paste is not the way to go in the OO/C++ world.

if i have to print 'u' then i have to execute this line
SendMessage(hTestWnd, WM_CHAR, (WPARAM) 'u', (LPARAM) 0);
but if i have to print character like
1-:
2-"
3-?
4->
etc
it does not work what to do?
SendMessage(hTestWnd, WM_CHAR, (WPARAM) ':', (LPARAM) 0);

What does the MSDN say ? I seem to recall that the higher half of your WPARAM value needs to be set to something other than 0 for non alpha characters, maybe ?

yea it should contain contains the scan code plus the virtual-key code.
let suppose i have both the scan code and virtual key code then how to form wparam from it ?
how to get scan code and virtual key code from wparam?

It appears Norm has provided a better answer anyhow.

Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002

SendInput
The SendInput function synthesizes keystrokes, mouse motions, and button clicks.
UINT SendInput(
UINT nInputs, // count of input events
LPINPUT pInputs, // array of input events
int cbSize // size of structure
);

Cool, Norm. I guess it WAS worth his while to keep asking this question for weeks. I had no idea this API existed....

i have an MDI application and I am able to save the Document . Now before the Document is saved and the FileDialog invoked i need to save some parameters . If i implement "ONFileSave()" in my view class I no longer get the File Dialog prompt.
I need to be achieving both .
1. Saving my changes
2. Then call the default save mechanism of windows
Also in the FileDialog that appears how do I specify the type of the File (i.e File FIlter). I want my documents to be saved with my custom File extension .
Please help

(Not sure) Try calling your document's OnFileSaveAs message handler inside yours.
If this does not work, Nish has written an article that may help you: CDocument::DoSave revealed[^].

i am having a window hwnd and i want to get its child window hwnd that has keyboard focus.

How do I determine the default browser of an NT-based (that is, NT 4/2k/XP/.NET) system? Is there an API call?
Actually, the simplest solution is to call ShellExecute() and just launch the HTML file. Is there a way to get an HWND for a console application?
Barring that, I need to determine the default browser, launch it, and have it open a specified URL.

I'm going to create a temporary window (::CreateWindow()), and then use that to call ShellExecute(). Can anyone see any problems with this strategy? Is there a better way to do this?

It appears you can just pass in NULL for the HWND.

I've looked at the MSDN example, but the pEnum->Next function returns S_FALSE which means that the number of filters that were requested to be enumerated, wasn't enumerated.
IGraphBuilder *pGraph = NULL;
IEnumFilters *pEnum = NULL;
IBaseFilter *pFilter = NULL;
ULONG cFetched;
HRESULT err;
<br>
CoInitialize(NULL);
err = CoCreateInstance(CLSID_FilterGraph, NULL, CLSCTX_INPROC_SERVER, IID_IGraphBuilder,(void**)&pGraph);
pGraph->EnumFilters(&pEnum);
<br>
while((err = pEnum->Next(1, &pFilter, &cFetched)) == S_OK)
{
FILTER_INFO fiFilterInfo;
char szFilterName[256];
pFilter->QueryFilterInfo(&fiFilterInfo);
WideCharToMultiByte(CP_ACP, 0, fiFilterInfo.achName, -1, szFilterName, 256, 0, 0);
SendMessage(GetDlgItem(ghWnd, IDC_FILTERS), LB_INSERTSTRING, -1, (LPARAM)szFilterName);
fiFilterInfo.pGraph->Release();
pFilter->Release();
}
<br>
pEnum->Release();
pGraph->Release();
CoUninitialize();
}
All help is apprecaited! Thanks all

Try calling pEnum->Reset(); before enumerating.

Wait... Seems you're constructing an IGraphBuilder and then enumerating its filters, but an empty IGraphBuilder won't have any. Try using for instance IGraphBuilder::RenderFile on some .avi prior to enumeration.

Thankyou i'll try that. But do you know if there's a way to enumerate all the available filters on the current machine?

I am trying to do something and the part that sounds the simplest is turning out to the hardest. I am putting a button on a toolbar. What this button will do is allow a user to set the button up to point to an executable. For instace, if the user wants this button to launch solitaire, it goes through the process of having the user find the .exe file. This is simple. The hard part is I am trying to use the icon from the .exe file as the bitmap for my button. And I cannot figure out how to do it. Any ideas? I have looked on this website but haven't found anything, it might be that I don't know where to look exactly...

Look for ExtractIcon in the documentation.
