I can only guess from your description that the coordinates you work with are wrong. Make sure you use coordinates relative to you point of reference... see GetWindowRect(), ScreenToClient(), GetClientRect().
|

I can sure the coordinates are right,but the methord I used to convert the coordinates is not very precise,which make the ListBox and the dailog`s proportion seem a little wrong. So can you give a more precise methord to locate the ListBox`s size and position? Thanks very much!

Please show the code, otherwise it is hard to help.

Now I have made it,I do like this:
CListBox m_List;// The ListBox;
CRect m_rcOldList;// The initialization WindowRect of the ListBox;
CRect m_rcOldWnd;// The initialization ClientRect of the Window;
OnSize(UINT nType, int cx, int cy)
{
m_List.SetWindowPos(NULL,m_rcOldList.left*cx/m_rcOldWnd.Width(),
m_rcOldList.top*cy/m_rcOldWnd.Height(),
m_rcOldList.Width()*cx/m_rcOldWnd.Width(),
m_rcOldList.Height()*cy/m_rcOldWnd.Height(),
SWP_NOZORDER);
}
This can work well,but there is still a problem, I want to define two variable:
int m_iPercentX;// The percent of the window`s client width has changed
int m_iPercentY;// The percent of the window`s client height has changed
OnSize(UINT nType, int cx, int cy)
{
m_iPercentX=cx/m_rcOldWnd.Width();
m_iPercentY=cy/m_rcOldWnd.Height();
m_List.SetWindowPos(NULL,m_rcOldList.left*m_iPercentX,
m_rcOldList.top*m_iPercentY,
m_rcOldList.Width()*m_iPercentX,
m_rcOldList.Height()*m_iPercentY,
SWP_NOZORDER);
}
But as you know, the m_iPercentX and m_iPercentY can`t be very precise, so the position of the ListBox will be a little wrong, how should I do? Thank you!

I see, this is a mathematical problem. Here a possible solutions, when calculating the position of a control don't throw away the fractions (of a pixel) and further resizing will be accurate. For an implementation see CResizeCtrl in method CResizeCtrl::CalcValue() plus bugfix!
Hope it helps.

I have written one program for which it needs Open SSL include directory. that I included in My projct written in C. Now I want to know what does the functions provided by the each header will do. Ofcourse I used a program which has been given in the Sun web site common to both C and Java, I want to know the definition especially for the function named BIO_ctrl() provided in bio.h header file.

While you may find someone here who is familiar with OpenSSL, it seems to me a much better
place to look is at the OpenSSL Website[^].
There's documentation there!

Hi All,
I have a SDI application with multiple interchange-able CFormView's. My app does not disappear from the task panel when no dialogs are opened, but when I open a dialog and switch to another app in the task panel (with Alt + Tab of course) and then switch back to my app the opened dialog doesn't have the focus any more and my app's icon from the task panel simply disappears! So I can not longer switch to my app with Alt + Tab!
I don't have this problem when opening a standard MFC dialog like CFileDialog. So the problem is with my dialogs.
I managed to set the focus on the opened dialog when switching in task panel by handling ON_ACTIVATEAPP into the dialog's window but the icon in the task panel is nowhere to be seen!
Any ideas? Thanks!
Regards,
Cosmin Unguru

When you create the dialogs, try to make sure they have the main application window as their parent. If they do not, they are getting the desktop as their parent, explaining perhaps your strange behavior.

Is it a Modal dialog box or Modeless?
Cheers,

They are all modal dialog boxes

I am looking for help how to output a chart into the arrays, all i was given was that i need to put a loop inside of a loop. The chart given is:
0 0 0 0
0 1 2 3
0 2 4 6
0 3 6 9
This is what I have so far:
<br />
#include "stdafx.h"<br />
#include "pattern.h"<br />
#include <br />
#include <br />
#include <br />
#include <br />
#include <br />
<br />
using namespace std;<br />
CWinApp TheApp;<br />
<br />
<br />
<br />
int main()<br />
{<br />
int j;<br />
int i;<br />
int test_score[4][4];<br />
<br />
for(i = 0; i < 4; i++)<br />
{<br />
for(j= 0; j < 4; j++)<br />
{<br />
test_score[i][j] = 0;<br />
cout<< test_score[i][j];<br />
}<br />
<br />
cout<<endl;<br />
}<br />
<br />
<br />
return 0;<br />
} <br />

Well, you have put zero in all of the array values. What do you need now?

I agree.

Study these two statements carefully. What does it look like they are doing? Do you see anything that would look like it would produce the "chart" you are after?

Give this a try
int test_score[4][4] = {
{0, 0, 0, 0},
{0, 1, 2, 3},
{0, 2, 4, 6},
{0, 3, 6, 9} };
...
cout << test_score[i][j] << ' ';
...

you need to replace the line
test_score[i][j] = 0;
with a formula that will give the chart in the answer
for example test_score[i][j] = i + j;
would give
0 1 2 3
1 2 3 4
2 3 4 5
3 4 5 6
think about it.

Hello, i have a problem to set new font for that list control!
I use SetFont(newfont); and the execution go to
OnSetFont(WPARAM, wParam, LPARAM lParam)
{
...
SendMessage(WM_WINDOWPOSCHANGED, 0, reinterpret_cast<lparam> (&wp));
...
}
after this execution should call
MeasureItem(LPMEASUREITEMSTRUCT lpMeasureItemStruct)
but program newer go to MeasureItem!
Any idea how to solve this?
regards
termal

WM_WINDOWPOSCHANGED is a notification message sent by the system. It is unrelated to setting
the font and you shouldn't be sending the message yourself.
Why do you think MeasureItem should be called? And more importantly, WHOs MeasureItem()?

Right. But this has nothing to do with setting the font and you shouldn't be posting that system
message.
If you want to redraw the control with the new font then you should invalidate it.
MeasureItem will be called automatically by the system when it needs sizes for the redraw.

You need to include "ws2tcpip.h" (this is stated in the documentation).
|
|
|
|
|
We make future? Your answer becomes a good seed...
|
|
|
|
|
ws2tcpip.h is already included in that code.
Pls check the link in my message
Is there any .lib files that I need to link in project settings??
