I was hoping it would suffice just to declare the message handlers in the base class and the framework would automatically route events to the base class without any work in the derived classes.
Technically,what you are trying to do, should work. But you might have one problem... Data Access.
Methods in the baseclass cannot access member variable in the derived class,
Plus for the events to work for the controls in both derived property page,they should have same IDC_XXX value.

This shouldn't be a problem since, as I told you earlier, the controls are shared between both property pages and therefore have the same IDC_ etc.
Therefore the member variables for each control etc. will reside in the base class and not be specific to each page (that's the whole idea anyways  )
So, you think this should be possible? Well, how about I have a go at it :p

sure, I think you should try it out with one control only and understand all the complexity involved with the solution.

The hWnd of the instance of my OCX Control is always 0x00000000! So I am unable to PostMessage() withing my control.
Nothing works... Even GetActualParent() as posted in the MSDN...
If anyone has encountered anything similar, or have an idea to get around this, please reply back as I'm stuck over this for more than 24 hours now!  confused:
Thanks,

I assume that you call GetsafeHWnd()in OnCreate(LPCREATESTRUCT lpCreateStruct) function or after it is called and not in Constructor as many times I do

Hi Pradeep,

Thanks for your reply!
My OCX is a wrapper for a hardware device - And doesn't need to create any window. So, I'm not handling WM_CREATE!
Now, if you make a similar OCX using MFC, and put it in a VB Form... Then try to debug the OCX code by making the VBClient.EXE with your OCX embedded in the VB Form, you can see that the OCX control's HWND is ALWAYS 0x00000000!
But if you insert the control in the ActiveX Test Container or another VC++ (MFC) client app, and then you debug your OCX code, you will see the OCX control's HWND has a legitimate value.
This is the problem, I have! (

There is no need for any separate thread to use CreateProcess(); It will return immediately after creating the new process.

Greetings!
What is the maximum limit of the number of items we can insert in combo box. How can i retrieve or increase this limit ?
|
|
|
|
|
Combo boxes use an integer to index the items, so the theoretical limit is 2GB-1. You'll run out of memory before you hit that limit, though. And on 9x, due to 16-bit limitations, the actual limit is 32767.

(i don't know at all what is the loan calculator, so i hope that will help, anyway, there was many articles when i searched for it, so i think if this doesn't satisfy you, you could search by yourself).

hi !
Does anybody know how to stop a process without killing it ?
What i needed was that my program hooked windows and get notification when explorer or any other windows component calls FindFirstFile(...)
my application gets a notification message.Now based on certain settings my program must allow FindFirstFile(...) to execute ,or prevent it from execution.I have proceeded till the notification part.Currently the app is notified when FindFirstFile(...) is called.But how do i stop it?
Also the app must be cross platform friendly ...and i don't have DDK so the solution can't be driver based...

I thought I knew what I was doing, but I can't come up with any way to initialize my static character array. It's defined, in the header file as
static char var[4]; In my source file I have tried every way I know of to give it a value to no avail. Any help is appreciated as I'm sure it can be done, I obviously have no idea how though.

I am afraid that I would not really understand your idea. But I give you here an example, it may help you.
<br />
class X{<br />
public:<br />
...<br />
private:<br />
....<br />
static char st[4];<br />
....<br />
};<br />
<br />
char X::st[4]="123";<br />
static char ss[4]="abc";<br />
....<br />
|

You normally don't put a static global variable in a header file; the purpose of using such a global is to restrict its visibility to one .CPP file.
You can give it an initial value in the .CPP file like so:
static char var[4] = "abc";
