Hi,
Okay this is the simplest expression:

private: System::Void timer1_Tick(System::Object *  sender, System::EventArgs *  e)
    {
       timerVal++;
       textBox1->Text = timerVal;
    }

This didn't work. I tried using the aforementioned class pretty much as shown in the example, and that gave me the message about an incorrect number of arguments.

This is surprisingly hard to find information on.

I noticed that other code category which might be more relevant. I felt the questions there seemed more advanced. I'm not averse to someone moving it if they think this is improperly placed.

Thanks,
Jeff

No offence, actually this forum is dedicated to unmanaged vc++, very few people gradute to managed vc++ from unmanaged vc++.

So, chances of finding a managed vc++ guy on unmanaged vc++ forum is less compared to managed vc++ forum.So just to help you, I mentioned it would be better if you post your query in appropiate forum.

Regarding moving your post, i don't haev authority to do so.. might be some from CP Staff can do it

Hi Alok,
I did actually post another question on the Managed C++ board. I'll use this board only if it's specifically a C++ question.

Thanks,

You could try

textBox1->Text = timerVal.ToString();

Looks like an assignment and no-one is interested in doing your assignments.Not even yourself.
It's not about fixing your program, you are looking forward for someone to write your complete code.

When eventually you'll write the code inside the functions, you'll find it just useless, because main calls no function at all.

how to convert byte array of .jpg and .jp2 images to Bitmap byte array in VC++?

Hai !
I have an byte array of an image. I donot know whether the image is an .bmp or .jpg or .jp2 image.
I want to convert this byte array into Bitmap byte array i.e I want to convert (.bmp or .jpg or .jp2) image to .bmp image?

Thanks!

Maybe you don't know the image format at all. How are we supposed to know it, instead?

You may try to interpretate your image data as RGB (or greyscale) components.

I will first try to gain knowledge in Images and their formats etc. all the stuff then i will try to code my requirement then i may iask my doubts to you.

Thanks!

For convert formats you can use of CImage class I dont think you can use of it for jp2 but you can find good article on the codeproject for helpful info about image formats search for CXImage article (of course you dont need to convert bmp to bmp Wink | ;)

Control not coming to the new method after .odl modification? [modified]

SIJUTHOMASP26-Apr-09 3:02

26-Apr-09 3:02

Hi,

I had to modify the .odl file for adding one more method. Any idea why its not coming to the newmethod while debugging..I have checked the MIDl and the tlb is created file with res.

test.odl

dispinterface _programctrl<br />
{<br />
[id(30)] boolean newmethod(BSTR var1,BSTR var2, BSTR var3, BSTR var4, BSTR var5);<br />
}<br />

The method is coming fine when I have tested on the activextest container but the problem is when I invoke the method it is not coming to the program while debugging..I have opted 30 as id random number.id[30]

I have called the method like this
testpgm.cpp

DISP_FUNCTION(testcontrl, "newmethod", newmethod, VT_BOOL, VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR)<br />
<br />
//<br />
BOOL testpgm::newmethod(LPCTSTR var1,LPCTSTR var2,LPCTSTR var3,LPCTSTR var4,LPCTSTR var5) <br />
{<br />
	<br />
	return TRUE;<br />
}<br />
<br />

testpgm.h
dispidnewmethod = 30L

Thanks,
Rahul..

I have resolved the issue finally with the following changes to the code given..

What I found was the DISP_FUNCTION usage couldn't exactly trace the id of the method..Instead when I used DISP_FUNCTION_ID, it started working..I have noticed that the DISP_FUNCTION_ID call having a parameter option to pass dispid of the method as well..Not sure why the DISP_FUNCTION couldn't work but anyhow my issue got resolved with DISP_FUNCTION_ID..

Similarly in the .h file I have changed 30L to just 30. Rest all are same..

//changed part of the code in testpgm.cpp <br />
 <br />
DISP_FUNCTION_ID(testcontrl, "newmethod",dispidnewmethod, newmethod, VT_BOOL, VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR VTS_BSTR)<br />
 <br />
//changed part in testpgm.h :<br />
public:<br />
enum{ <br />
dispidnewmethod = 30, ..

extern CString m_gsADDRESSHOM; // set into file stdafx.h

It's a global variable - that means it's not a member of dlg7, so don't treat it as if it were.

Do you think you maybe need to read an introductory C++ text[^], to learn these basics?

constructor and OnInitDialog()

durban225-Apr-09 21:21

durban2

25-Apr-09 21:21

MFC, STUDIO 2008, MDI

Why ignore ( skip ) value from OnInitDialog()
There are modal and modeless windows:

// modeldlg2.h
class CMainDlg2 : public CDialog // modal window
{
public:
virtual BOOL OnInitDialog();
CString m_sPP_modal7;
};

// adderdlg2.h
class CAdderDialog2 : public Cdialog // modeless window
{
public:
virtual BOOL OnInitDialog();
};

// modeldlg2.cpp : implementation file

CMainDlg2::CMainDlg2(CWnd* pParent /*=NULL*/) // standard constructor
: CDialog(CMainDlg2::IDD, pParent)
m_sPP_modal7 = "Paris";
}
BOOL CMainDlg2::OnInitDialog()
{
CDialog::OnInitDialog();
m_sPP_modal7 = "New-York";
return TRUE; // return TRUE unless you set the focus to a control
}

// adderdlg2.cpp : implementation file MODELESS window
BOOL CAdderDialog2::OnInitDialog()
{
CDialog::OnInitDialog();
CMainDlg2 dlg7;
MessageBox(L"dlg7.m_sPP_modal7 = \n" + dlg7.m_sPP_modal7);

Why have been chose value from constructor but not from
the method OnInitDialog() modal window?
}
Result: Paris
Why not New-York ?
How to receive New-York ?
