C / C++ / MFC

Good day!
I have a little Problem with the MFC...
I have a static box for Pictures. I use a global variable. This variable changes...

now my problem: i want that different pictures change in my static box -> the global variable must control the picture box.

Example: I have 3 Pictures: IDB_PIC1, IDB_PIC2, IDB_PIC3...

now the variable has (is an integer) contains 1-> the static box must now show the first picture (IDB_PIC1), than the variable changes to 2 -> now the static box must show me the picture2 (IDB_PIC2)

how can i realize this? Confused | :confused:

Make them strings! In the resource editor when naming them surround them with quotes. For eg: "IDB_PIC1"

Now you can get the name of the picture you want based on the global variable like this...

CString picToBeUsed;
picToBeUsed.Format("IDB_PIC%d", g_globalVariable);

Now load the bitmap and place it on the static control.

CBitmap bmp;
bmp.LoadBitmap(picToBeUsed);

m_static.SetBitmap(bmp);

I did it! But there is an error...

Name of Pic.: IDB_PIC1
Name of Global variable: Promille
Name of the static Picture Box: IDC_PIC_Moe

void CAlkoholmaschineDlg::OnB_Likoer(){

CString IDB_PIC1;
IDB_PIC1.Format(IDB_PIC1, Promille);
CBitmap bmp;
bmp.LoadBitmap(IDB_PIC1);
IDC_PIC_Moe.SetBitmap(bmp);
}

The error message:
error C2228: left of '.SetBitmap' must have class/struct/union type

It's not LoadBitmap it's SetBitmap.

ok this works:

CBitmap bmp;
bmp.LoadBitmap(IDB_PIC_Moe1);
CStatic *pPicStatic = (CStatic*)GetDlgItem(IDC_PIC_Moe);
pPicStatic->SetBitmap(bmp);

THX VERY MUCH!

But this won't solve your problem. This won't change the picture based on a global variable.

Hello fellows. I've been wondering, how can I perform a soft-reset (cold-reset) from a CAB installation file?

Thanks. I'm trying to restart my pocket pc indeed, but not from a common program, but from a cab installation file.

Hi,

I need to implement an ActiveX control in a simple Dlg based MFC application.
This controls scans the serial port after messages and sends them to my application
( Sniff | :^)

in theory that is)
In a VB application there is no problem to receive the event. But i need it in VC (MFC)
the init of the object seems to work and the messages should be sent (trace line in the
on_fire call) but i don't receive anything in my dlg.

I think that i missed some small init to work with events but i simply can't rememeber
what or wich. Any pointers would be very appriciated.

The following is for MSVC6. If you right click on the ActiveX control on the dialog and select "Events..." a dialog appears which will let you add event handlers.

Hi
I did that and a new member functions is created but i never seems to fall into
that function.
Very strange ???

I tested it with the calendar control and it works fine. I would guess the control isn't actually firing the event.

Ok
i've done some deep debugging into that altough the Fire_Message is called
there are no connections (connected appz) for this control ????

how is this possible ??? I have attached my project(activeX control) to the
test application (MFC dlg) and I am falling into a breakpoint in the
Fire_Message function, but there is no connection ???

Something wierd is going on.

Any idea on the "lint !e740" part? Is this a comment I should understand?

It all depends on the context (e.g., how did it get there (Lint is assumed)? what code is it near?), I guess.

They want to ignore the Error 470 that the lint might have output for the following code.

You can maybe find out wht PC-Lint Error 470 is, and then that would give you some idea of what potentially squirelly code you are looking at.
