Ah! So, instead of sending a BM_CLICK message to the button, send a WM_COMMAND message to the view, like so:

Call SendMessage(hViewHandle, WM_COMMAND, IDC_HIDDEN_BUTTON_1, 0);

Tried your idea - wasnt happy with that either. The BM_CLICK works. I'll be using this feature if/when i have to implement the cancel . ONly thing I'm wondering about is how do you terminate my dll at cancel . I need to look at the task timer before I ask any more questions...
Have fun!

A better design

From a design point of view, it's better to keep the knowledge of the hidden button (or menu) id within the view itself, by creating a public method that anyone can call. That way, you don't share resource ids across classes or (heaven forbid!) DLLs! Here's how:

Declare a public method in your view, eg:

void doSomething();  // do something

The implementation should send the view the hidden button command message, eg:

void CMyView::doSomething()
{
  SendMessage (WM_COMMAND, IDC_BUTTONHIDDEN1);
}

Form Resizing

Hi! I'm using a Form, derived from FormView, and, by code i'm dynamically filling it with static objects, i would like the form (has a vertical scrollbar) to resize as the objects are being created.

Thank you Roger, but i could not find such function in MSDN (i'm using .NET).
Do that function really resizes my form?

Thanks

nID - in create

ns24-Sep-02 5:44

24-Sep-02 5:44

I asked this I think a very long time ago and cant find the thread. Basically in the create function for a CProgressCtrl,

BOOL Create( DWORD dwStyle, const RECT& rect, CWnd* pParentWnd, UINT nID );

The nID is something we have to generate via the string table or the resource symbols,since we dont have a control on a dialog or anything... is that correct?

Thanks,
ns

If you don't have any controls except progress bar, then use any integer value for nID.

sendmessage parameters question

ns24-Sep-02 5:37

24-Sep-02 5:37

I've so far used this format

pView->SendMessage(WM_COMMAND,IDC_BUTTONHIDDEN5,0);

because all I wanted was to trigger the handler. Now i want to give the handler an integer value from the sender to process.
Now if I did put the integer value into the sendMesssage, how would my handler access it? Or cant I use this technique for what I want to do?

Thanks,
ns

Unfortunately you can't do this thru SendMessage() because it's handled in a stock way.

However, if you're using a doc/view interface (as I think you are), you can call UpdateView() and pass it a "hint" (an application specific DWORD). The hint allows the receiving view to respond in an appropriate manner (eg: execute the IDC_BUTTONHIDDEN5 handler with a certain context).

The identifier IDC_BUTTONHIDDEN5 leads me to believe you're using the hidden button to respond to app specific messages. This is a common technique, but you may find it easier to use a custom menu command instead of adding buttons to the view/dialog. Just create a new menu resource (I call mine MENU_HIDDEN_COMMANDS) that contains all your hidden commands. A major benefit to doing this is that your hidden command ids will always be unique, allowing these messages to be posted to any view/dialog. Buttons ids are only guaranteed to be unique within the dialog on which they reside.

Hope this helps!

Great idea.....

Meanwhile, another sendmessage question...
I want to send the progressbar a 1026 which is PBM_SETPOS. I am trying to see if this sendmessage works since my PBM_STEPIT isnt working I think.

SO how do I send the pos in this API sendmessage (unfortunately its from a VB dll). This is what I have to send and I dont know how to find out what the progressbar recognises as its position (wParam or LParam);
How does one get a hold of such info (sendMessage parameters)

Thanks,

Re: sendmessage parameters question

Ravi Bhavnani24-Sep-02 6:33

From VC++'s online help, PBM_SETPOS treats wParam as the new position and ignores lParam (which should be zero).

Sir,
I am developing the code for rotation of the Rectangle and ellipse in my projects.I have seen hat SetWorldTransform() cannot function in 98.So I am searching for alernative method to rotate my rect.I should be able to save the rotated rect in my List containg the CRect objects.I would be thankful to you if I get The solution as soon as possible as it is to be embedded immediately
..............
I have rotated the rect by using XFORM structure and calculated the new values and have drawn the rotated rect using Polygon() function.But I am unable to modify my List rect object with these coordinates as that draws from the TOPLEFT to BOTTOMRIGHT

Sir u can provide any of the solution.

Waiting for ur reply

It sounds like you will simply need to create a new list and a new structure that can hold the four points that you need to store your rectagle. Or you could use your CRect class and the XFORM class, and you could generate the new rectangle on the fly with a conversion function that returns the translated points.

There is not a whole lot of native support for anything in windows that is not axis aligned.

Looking for a "Variable Watch" control

Hi !

I'm looking for a custom control to provide a "variable watch" like control.

You can find such controls in every environments such as Visual C++ ...

It allows you to display the name and the value of variable selected by the user :

myVariable1 ....................... 0x12485
myVariable2 ....................... 48725
myVariable3 ....................... 1001100
myVariable4 ....................... 0x20 0x42

Does anyone knows where to fing such a control ???
Thanks,

Vince

What i'm looking for is not where to find the watch window of Vc++ !!!

I'm looking for a class witch wrap functions of a watch window in order to be integrated in my own application (something like a Cwnd derivated class...)

ReleaseDispatch

ns24-Sep-02 4:47

24-Sep-02 4:47

I have

	p.CreateDispatch("DllwithForm.Class1");

//	AfxMessageBox("pbar");

	p.CheckingPB(hPbWnd,0,100000);

	//p.ReleaseDispatch();

where CheckingPB is triggering repeated messages to be sent to a control. If I uncomment the release dispatch , I am concerned that it will release the dispatch before all my messages have been sent and received. Is this a fact? Since the app isnt working anyways I cant check it out, but wondered if its disastrous if that line is commented out...

Thanks,
ns
