Hi All,

Using CSplitterWnd class I can split the window in row X column statically.
But I want to split the window as shown below:

|---------------------------|
|      |                    |
|------|                    |
|      |                    |
|      |--------------------|
|      |         |          |
|      |         |          |
|------|--------------------|

How can I do this?
Please, any one has the code for it? any clues?

Thanks & Regards,
Neeranjan

Search MSDN for the GENSPLIT example. It has four panes.

How to debug this ???

My dialog application is running more instances of itself
by calling CreateProcess() to run some tasks (no, i can't use threads).
Is there some way how to debug not only main process, but also child processes, to check memory leaks, see TRACE output, etc ?
Attaching another visual studio instances to all child processes is
lot of work and it can't catch events before before debugger attaching.
Any idea how to do this ?

Thanks !

add the line

SAFEARRAY in VC/VB/Scripting-Interface

A question how typical Dispatch-Interfaces are designed:

Imagine you provide a Script client with a method returning a safearray, like this:
HRESULT GetData([out, retval] SAFEARRAY ** data)

Do you return a "complete copy", or can/should you return a reference to internal data held by the component?

we are here to help each other get through this thing, whatever it is Vonnegut jr.

I would have thought that you would need to return a copy.

I don't think you can access data across processes just by reference, some sort of accessor functions would be required.

Ofcourse it will be a reference to the actual memory location allocated from the com server.

A SAFEARRAY we create using by SafeArrayCreate or a BSTR we create by using SysAllocString are independent of the component which creates them. The client can manipulate the server allocated memory location. Remember in the case of a BSTR, the server calls SysAllocString and the client has the responsibility to call release by calling SysFreeString. Its like the server calls new and the client calls delete.

Or it is just like a com object we create inside a com server ( using CComObject ) and a cleint manipulates the properties of that server created object.

hope this helps..

Max limit in resource.h file of VC++

PrashantJ5-Aug-04 22:27

5-Aug-04 22:27

Hi,

We specify the next step number for the resources, commands and control by the following.
_APS_NEXT_RESOURCE_VALUE
_APS_NEXT_COMMAND_VALUE
_APS_NEXT_CONTROL_VALUE

Do we have any way to restrict the numbers or specify the max limit.

eg. I want my resource to have command values from 1 to 100. So
#define _APS_NEXT_COMMAND_VALUE 1 // Next command number

Can I specify somewhere in the resource.h file saying 100 is the max if it goes beyond 100, throw an error?

Thanks,
Prashant.

No, just don't add more than 100 of that type of resource.

you will have to edit the registery,
create a key HKEY_CLASSES_ROOT\.net
with a default value of "NETFILE"
then create the key HKEY_CLASSES_ROOT\NETFILE
to give it an icon
create a sub key named "DefaultIcon" and set its default value to the path of the icon you want to use
then to add menu items to it create another sub key under NETFILE named "shell" then create a sub key under it, with the menu item name then under that key create yet another sub key named "command" and set its default value to the command line you want to use for that menu item, for example

"HKEY_CLASSES_ROOT\txtfile\shell\open\command"=
"C:\WINDOWS\NOTEPAD.EXE %1"

if you arent familiar with editing the registery this will sound very confusing, but its really not, you might check out the articals on shell extensions, i dont know if they cover this or not

If you call StartServiceCtrlDispatcher() and your program is running as a 'regular' executable, you will certianly get this error. The StartServiceCtrlDispatcher() call will only succeed when the service control manager is starting your program. So, if you are running your EXE and starting it under the debugger, then you will ALWAYS see this error. Perhaps you did not fill in the SERVICE_TABLE_ENTRY data correctly. If you did, check the registry to make sure your service got 'installed' correctly.

a Dialog Bar Question !

hi all

now i am doing a SDI project, all of the views are CFormview Derived , and switching the formviews according to the menu commands.

i want to implement a Dialogbar to my container, in such a way that i can show the status messages on that. i created the dialogbar from a dialog template and attached with the dialogbar object.
i need a static control in the dialog bar inorder to show the status in each forms. how can i set the static text in dialogbar ???
like static_Control_variable_in_dialogbar.SetWindowText("test ");

Any idea..??

programming in VB is like riding a kiddy bike, while programming in C++ is like driving a Formula 1 racing car

Re: a Dialog Bar Question !

Bhaskar5-Aug-04 23:11

Since the dialogbar object is a member of frame class. You need to get the dialog bar object through AfxGetMainWnd.
Check this

void CTestView::OnBnClickedButton1()<br />
{<br />
	CMainFrame *pFrame = (CMainFrame*)AfxGetMainWnd();<br />
	if (pFrame)<br />
	{<br />
		pFrame->m_wndDialogBar.SetDlgItemText(IDC_MYSTATIC, "Hello");<br />
	}<br />
<br />
}

This is a message handler of a form view class
The m_wndDialogBar is a public member of CMainFrame class
IDC_MYSTATIC is the id of the static control in the dialog bar. You must change the id of a static control from IDC_STATIC to another.
