What Hotkey would you normally associate with Delete or Clear?
MS Word claims it to be 'Del' but I want to use this with Rich text, therefore a hotkey would clear the whole selection, formatting included.
All the Ctrl + ? hotkeys seem to be located on the left of the keyboard, so which would you choose for a Delete?

Ctrl + X, just in case 
~RaGE();

That was my first thought, but Ctrl+X is reserved for Cut operations, which would fill the clipboard. I want the users to be able to clear the control and still have tho option of pasting anything they may have previously copied.
I have used Ctrl+D for now, but I was wondering if there was any national standard as with Cut, Copy and Paste.

That sounds good, Ctrl + Shift + X it is :->

Sorry, my post was a bad attempt at humour. The "just in case" was supposed to mean "so that we can paste it back in case we did not really want to delete it". 
Seriuosly, Shft + Ctrl + X is a bit too much keys to my taste. I find Ctrl + D better. My 2 cents.

haha, man I must be way too tired if I didn't notice that. I would agree Ctrl+D is better. At the moment I will leave it as it is and look further into the Richedit hotkeys. I don't want to have to many over-rides.

I have a program where i have created an openGL window within an MFC Dialog using a tutorial on http://steinsoft.net . I have buttons on the Dialog which i want to use to rotate and move (translate) some objects that i have drawn.
I implemented some code from http://nehe.gamedev.net/data/lessons/lesson.asp?lesson=10[^] to allow me to move around the objects.
The code seems to be almost correct, but there seems to be a problem with the focus, coz something is stealing the focus, and thus the events are not getting executed properly.
Could someone please tell me how to get around this.
Your help would be highly appreciated
Thanks in advance
If you need my project to look at it for further clarification, you could post your meail address here and i'll mail it to you...

Since i would like the rotation and translation to happen either by pressing buttons or key-presses, i have the following code: (NB: Without the message boxes it doesn't work, but with them ... it seems to send the focus back to the correct control - which i'm not too sure whether it's the dialog itself or the GLWindow within the dialog)
BOOL COpenGLMFCDlg::PreTranslateMessage(MSG* pMsg) <br />
{<br />
<br />
<br />
if (pMsg->message == WM_KEYDOWN)<br />
{<br />
if (pMsg->wParam == VK_RIGHT){
openGLControl.myRightButton = true;<br />
<br />
m_Txt_ObjectTypeName.SetWindowText("Right fired"+(CString)(openGLControl.yRotation));<br />
}<br />
<br />
if (pMsg->wParam == VK_LEFT){
openGLControl.myLeftButton = true;<br />
::MessageBox(0,"One more Event fired","My fired Event",MB_ICONINFORMATION |MB_SYSTEMMODAL|MB_DEFAULT_DESKTOP_ONLY);<br />
}<br />
<br />
if (pMsg->wParam == VK_UP){
openGLControl.myUpButton = true;<br />
::MessageBox(0,"Up Event Fired","Up Event",MB_ICONINFORMATION |MB_SYSTEMMODAL|MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
}<br />
<br />
if (pMsg->wParam == VK_DOWN){
openGLControl.myDownButton = true;<br />
}<br />
if (pMsg->wParam == VK_PRIOR){
openGLControl.myPageUpButton = true;<br />
::MessageBox(0,"Page Up Event fired","PageUp Event",MB_ICONINFORMATION |MB_SYSTEMMODAL|MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
}<br />
if (pMsg->wParam == VK_NEXT){
openGLControl.myPageDownButton = true;<br />
<br />
}<br />
<br />
}<br />
return CDialog::PreTranslateMessage(pMsg);<br />
}
Above was the code for keypresses... now for the buttons events code
void COpenGLMFCDlg::OnCmdUp() <br />
{<br />
openGLControl.myUpButton = true;<br />
::MessageBox(0,"Up Button Event Fired","Move Forwards",MB_OK|MB_ICONINFORMATION |MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
<br />
}<br />
<br />
void COpenGLMFCDlg::OnCmdRight() <br />
{<br />
<br />
openGLControl.myRightButton = true;<br />
<br />
<br />
::MessageBox(0,"Right Button Event Fired","Turn Right",MB_OK|MB_ICONINFORMATION |MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
}<br />
<br />
void COpenGLMFCDlg::OnCmdLeft() <br />
{<br />
openGLControl.myLeftButton = true;<br />
::MessageBox(0,"Left Button Event Fired","Turn Left",MB_OK|MB_ICONINFORMATION |MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
<br />
}<br />
<br />
void COpenGLMFCDlg::OnCmdDown() <br />
{<br />
openGLControl.myDownButton = true;<br />
::MessageBox(0,"Down Button Event Fired","Move backwards",MB_OK|MB_ICONINFORMATION |MB_DEFAULT_DESKTOP_ONLY);<br />
<br />
<br />
}
This is the onPaint() function
void COpenGLControl::OnPaint() <br />
{ <br />
<br />
glEnable( GL_POLYGON_OFFSET_FILL );<br />
glPolygonOffset( 1.0, 1.0 );<br />
DrawGLScene();<br />
glDisable( GL_POLYGON_OFFSET_FILL );<br />
<br />
glEnable( GL_BLEND );<br />
glEnable( GL_LINE_SMOOTH );<br />
glBlendFunc( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA );<br />
glPolygonMode( GL_FRONT_AND_BACK, GL_LINE );<br />
DrawGLScene();<br />
glPolygonMode( GL_FRONT_AND_BACK, GL_FILL );<br />
glDisable( GL_LINE_SMOOTH );<br />
glDisable( GL_BLEND );<br />
<br />
<br />
<br />
CWnd::OnPaint();<br />
myRightButton = false;<br />
myLeftButton = false;<br />
}
I think the issue is something to do with the focus being lost somewhere to some control. onPaint an drawGLscene are in the OpenGLControl functions
Hope this helps...

I Get xml files from the internet by using CWebBrowser2 control, now is the question:
How can I save the xml as files on my disks and don't indicate the user?
Now I Get the xml source from CWebBrowser2 by the method CWebBrowser2::ExecWB(OLECMDID_SAVEAS, OLECMDEXECOPT_DONTPROMPTUSER, &vt1, &vt1), is there any way better?
thanks for your answers!

Hi!
This is a really easy question, but I dont know the answer:
The text in a AfxMessageBox should look like this:
Sorry, can't found folder "Test" !
Whats the way to give out the ""?? 
Thanks

|
|
|
|
|
|
it is "Sorry, cannot find the folder \"Test\"". :->
~RaGE();

Any ideas why this code crashes with 799 elements or more but it works with 699 or less? I haven't found yet the limit.
<code>#include <malloc.h>
#include <stdio.h>
int main()
{
int n = 699;
int* array = (int*) malloc(sizeof(char) * n);
if (!array)
{
printf("Out of memory");
return 1;
}
for (int i = 0; i < n; i++)
{
array[i] = i;
}
for (int i = 0; i < n; i++)
{
printf("%d, ", array[i]);
}
return 0;
}
</code>

Hey when i tried it is working up to n=980.

What compiler? I'm using mingw on WinXP Home right now but I could try it later on VS2005 and GCC under Linux but I have to reboot.
This is a text book example. Well I've change it a little bit but it is basically the same.

Your array variable is a pointer to int's but you're only allocating enough memory for n char's. char's are smaller than int's so you're running past the end of the memory you've allocated.

Hi,
I'm using a CButton as a check box in my application.
The background of the window on which this button "sits" is white.
When the check box is created it has a grey background no its rect.
Do you know how to control the background color?
Thanks.

use :
afx_msg HBRUSH OnCtlColor( CDC* pDC, CWnd* pWnd, UINT nCtlColor );
