Well, I set the cursor to the WAIT one, using SetCursor / LoadCursor. Look up the function for yourself, and the answer to your question will become obvious.

Hi
I am working with zooming the images , its almost done but i need little confusion with how to save the images from output form of ::StretchBlt()
this is my code snippet
CImage __ImageZoom,imgout;
CBitmap __cb;
__ImageZoom.Load(L"ZoomImage.TIF");
HDC hdc,hmemdc;
hdc = ::GetDC(NULL);
hmemdc = ::CreateCompatibleDC(hdc);
::SelectObject(hmemdc,(HBITMAP)__ImageZoom);
::StretchBlt(hdc,0,0,624,694,hmemdc,0,0,__ImageZoom.GetWidth(),__ImageZoom.GetHeight(),SRCCOPY);
imgout.BitBlt(hdc,0,694);
imgout.ReleaseDC();
imgout.Save(L"Sample.tif");
Thanks

I suppose you should use
imgout.Create(624, 694, __ImageZoom.getBPP());
__ImageZoom.StretchBlt(imgout.getDC(), 0, 0, 624, 694);
imgout.ReleaseDC();
imgout.Save(L"Sample.tif");

Thanks for your replay

You're right, I missed a step. Anyway I've fixed my previous answer, check it out.

Nope, not with CreateProcess.

Hello!
Cannot figure this out for two days already...
Example:
Header file:
<br />
<br />
#pragma once<br />
#include "afxwin.h"<br />
#include "afxcmn.h"<br />
<br />
<br />
<br />
class CUsersForm : public CDialog<br />
{<br />
DECLARE_DYNAMIC(CUsersForm)<br />
<br />
public:<br />
CUsersForm(CWnd* pParent = NULL);
virtual ~CUsersForm();<br />
<br />
enum { IDD = IDD_USERS_FORM };<br />
<br />
protected:<br />
virtual void DoDataExchange(CDataExchange* pDX);
<br />
DECLARE_MESSAGE_MAP()<br />
public:<br />
<br />
afx_msg void OnBnClickedGendataButton();<br />
<br />
CWnd* GenDataButton;<br />
<br />
void InitDataFields(void);<br />
virtual BOOL OnInitDialog();<br />
};<br />
<br />
<br />
Code file:
<br />
#include "stdafx.h"<br />
#include "UsersForm.h"<br />
<br />
<br />
<br />
IMPLEMENT_DYNAMIC(CUsersForm, CDialog)<br />
<br />
CUsersForm::CUsersForm(CWnd* pParent )<br />
: CDialog(CUsersForm::IDD, pParent)<br />
{<br />
<br />
}<br />
<br />
CUsersForm::~CUsersForm()<br />
{<br />
}<br />
<br />
<br />
void CUsersForm::DoDataExchange(CDataExchange* pDX)<br />
{<br />
CDialog::DoDataExchange(pDX);<br />
}<br />
<br />
<br />
BEGIN_MESSAGE_MAP(CUsersForm, CDialog)<br />
ON_BN_CLICKED(IDC_GENDATA_BUTTON, &CUsersForm::OnBnClickedGendataButton)<br />
END_MESSAGE_MAP()<br />
<br />
void CUsersForm::OnBnClickedGendataButton()<br />
{ <br />
this->GenDataButton->ShowWindow(SW_HIDE);<br />
}<br />
<br />
<br />
BOOL CUsersForm::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
this->InitDataFields();<br />
return TRUE;
}<br />
<br />
void CUsersForm::InitDataFields(void)<br />
{<br />
this->GenDataButton = GetDlgItem(IDC_GENDATA_BUTTON);<br />
<br />
}
The point is - this is just a sample code. I need to create an array of pointers to dialog items (CWnd type) for later use in this class. How do i accomplish this?
Please at least point me to the right documentation about this issue.. Is this something with variable types (static etc)..
Thank`s

}
GenDataButton is a CWnd*, not a HWND. So, write this instead:
this->GenDataButton = GetDlgItem(IDC_GENDATA_BUTTON);

How can this line compile?
Why don't you map a control variable using the Add member Variable Wizard of Visual Studio?

Sorry - I`ve tried this also - does not work - the GendataButton is valid right after the call to InitDataFields -
if I call InitDataFields() just before a call to GenDataButton->ShowWindow(SW_HIDE) - it works, bu after exiting the OnGenDataButton scope the GenDataButton pointer is emtpy..

Hi All
How can i read environment variable rom c program

If you are under windows (using VC++) then you can use GetEnvironmentVariable[^]. Otherwise maybe give getenv[^] a try.

Every C program takes 3 arguments on the main function.
The 3rd parameter is a pointer to the environment block.
int main(int argc, char* argv[], char* envp[])
{
return 0;
}

Hi Experts,
I want a CListCtrl with Checkbox and Report View in which some item should be selectable and remaining should not.
How can I do that?
|
|
|
|
|
Try handling the LVN_ITEMCHANGING[^] notification, examine which item is about to change anf if it is one that is not allowed, return TRUE to prevent the selection/checking. Hope that is what you need...

But I want also make these item different(Not Selectable) from other List Item(Selectable).
|
|
|
|
|
Then you will have to go with ownerdrawn[^] items i believe.

Hi to All,
In regards to previous problem of mine,...I have made an overloaded construtor of dialog class in dialogB...Now while creating the object of the dialog , I am passing the variables...No problem the overloaded contrctor of dialogB calls fine. But again, the default constructor is getting called. Why so?
my code line to create the dialog is...
dialogB obj = new dialogB(&m_boardMainPage,&m_portMainPage,&m_extMainPage);
obj.DoModal();
I need to create the dialog with overloaded constructor (in order to pass some valued to that dialog)..Please help me.
-----------------------------

You have classA, and classB inheriting from that.
You make a new classB, and both classB::classB() and classA::classA() are getting called?
This is not a bad thing. This is a GOOD thing.
Imagine if this was not the case. CDialog is a slightly complex class. You make a new dialog. Your constructor would have to do all the special work of your new class. AND ann the special work of a CDialog. AND all the special work of a CWnd. AND all the special work of a CObject.
(It's turtles all the way down).
If you want to control which CDialog constructor gets called, you need to do the following:
CMyDlg::CMyDlg (CWnd *pParent)
: CDialog (IDD_MYDLG, pParent)
{
In addition - the base class constructor gets called first. Again, imagine if it was the other way around. All the stuff not included in the inheriting class would be uninitialised.
I hope that helps,
Iain.

A guess what's causing this behavior: If you pass a variable of class dialogB in a function call, the default constructor will be called to create a second instance of dialogB.
If this is happening and you want to avoid this behavior, pass the address of the dialogB object, rather than the object itself.
