If you could put your images into icons... you could do that this way:

AfxGetApp()->LoadIcon(MY_RESOURCE);

Hope it helped.

<br />
HICON my_icon = AfxGetApp()->LoadIcon(MY_ICON /* Here type your resource */);<br />
<br />
m_button1.SetIcon(my_icon, 1 /* This is for setting big or little, 1=big, 0=little */);<br />

OR:

<br />
HICON my_icon = (HICON)LoadImage(AfxGetInstanceHandle(),MAKEINTRESOURCE(MY_RESOURCE),IMAGE_ICON /* don't change this */,16,16,0);<br />
<br />
m_button1.SetIcon(my_icon, 1);<br />

Hope it helped.

If /* This is for setting big or little, 1=big, 0=little */, then why does SetIcon needs 1 to load a small icon?

Not clear enough?
Oki.

If I generate a Dialog Based MFC App and I delete the call SetIcon(m_hIcon, FALSE) on OnInitDialog, the small version of m_hIcon will be loaded. But if I delete SetIcon(m_hIcon, TRUE), the big version will be loaded and converted to a smaller one.
Why is this?
Is my version corrupted or something??

What I was wanting to do, for demonstrative purposes only, is give the impression that my program is printing an item, followed by another, and so on.

The program is a dialog box. There is an Edit box that has a title of a chart to print. What I want the program to do is display chart one, generate a delay, then display chart 2, and so on, giving the appearance that the application is printing each chart.

The problem is is when I call UpdateData(FALSE), the dialog does not update immediatly, so of course the following doesn't work.

m_chart = "Chart1";
UpdateData(FALSE)
Sleep(1000);
m_chart = "Chart2";
UpdateData(FALSE)
Sleep(1000);
....

How do I go about doing this?

You could use a timer. Have a look at WM_TIMER and OnTimer in MSDN.

How to determine the focused control?

20-Oct-03 8:12

Well, there is another way instead of using control variables:

From MSDN:

<br />
CWnd::SetDlgItemText(int nID, LPCTSTR lpszString);<br />

So you would be able to type and run this:

<br />
SetDlgItemText(MY_RESOURCE, "I am alive");<br />

Applying this to your source code would be:

<br />
// m_chart = "Chart1";<br />
// UpdateData(FALSE)<br />
SetDlgItemText(MY_RESOURCE, "This is my first text");<br />
Sleep(1000);<br />
// m_chart = "Chart2";<br />
// UpdateData(FALSE)<br />
SetDlgItemText(MY_RESOURCE, "This is my second text");<br />
Sleep(1000);<br />

Hope it helped.

Hi there

I have a CFrameWnd with a CTreeCtrl and a CListCtrl ... If a user selects a control it automaticly got the focus (Yes its the truth Smile | :)

) ... but how to determine which control got the focus?

Thanks for reading Wink | ;)

Re: How to determine the focused control?

The GetFocus() method will return a pointer to the window that has current focus. From that it will be easy enough to determine which window has focus.

Or you could handle the CWnd::OnSetFocus even for each control.

Re: How to determine the focused control?

20-Oct-03 6:40

You could do something like this:

<br />
CWnd* pWnd = CFrameWnd::GetFocus();<br />

Then you can work with pWnd, when really you are working with the control that has the focus. For testing purposes you can try this:

<br />
CWnd* pWnd = CFrameWnd::GetFocus();<br />
<br />
pWnd->SetWindowText("THIS WORKS MAN !!");<br />

Hope it helped...;)

Bandwidth Limiting

I'm looking for a way to limit the tcp/ip bandwidth of an application (or set of applications) from another application.

Basically I need to provide the facility to limit the upload and download KBytes/Sec of a set of processes, with the limits set by the application I am writing.

I know this is possible (as there are a number of applications out there that can do this, www.netlimiter.com is one example), however I need to be able to include the functionallity in my own program.

Any suggestions of what approach to take, where to look for ideas etc...?

Thanks...

You can use Network emulator tool-kit for windows.
Find it here http://www.gonetdotnet.info/posts/how-to-test-an-application-in-limited-bandwidth. You can find how to configure and use Network emulator tool kit for windows to test your application in limited bandwidth.

I'm currently modifying a program originally written in C, and I'm fairly inexperienced in programming using MFC and Visual C++
I have a class that gets read in from a menu command, which works OK.
How can I access this class from the automatically generated View classses so that I can display it?
Any help and/or comments are welcome

If you have the class in your document class use GetDocument() in your view class to get a pointer to the document and access the member variable from there.

Program the router to do so. For non sophisticated users, set up a firewall on the PC in question.
