NT = 2K = XP

I'm going to patent thought. I have yet to see any prior art.

Over the years I have developed on all the operating systems. There are only 3 things I can tell you:
1) Years ago I used to have the believe that if you could get an app to compile on old 95/98 machines it would have a better chance of working without modification on newer OS (NT). You would be supprised at how many developers ignore the footnotes for a function at the end of the MSDN literature that specify what operationing systems support them only to get burned later. Lately though I have decide to develop on the latest OS because of the next paragraph. Read on...
2) I have noticed that an application developed on 2000 using VC7 produces a GUI appearance that looks the same on 2000 and XP (that is the old style buttons etc.). Whereas the same application developed on XP will have the newer buttons (mouse hover hite etc..)and interface appearance when viewed on XP and the older but standard appearance on 2000.
3) Visual studio.Net won't work on anything older than 2000 so you might as well forget the older OS for developing.

I want to programmatically control the mouse cursor- like they do in all those playback demos and stuff like that. The mouse cursor should not only move to the coordinates defined in the program, but also click.
Secondly, how can I do the same for keyboard? I mean, I should be able to issue keyboard key commands from a program.
Thanks for your help.

Well as far as the keyboard goes, normally you'd be doing that all internally anyway. For instance, let's say you're writing a game in which the up-arrow key moves a character forward. Well, you're already going to have written a function like MoveForward which is called from the up arrow key. If you want to simulate this behavior, just call MoveForward from somewhere else,, the key itself is irrelevant.
It's the same with the mouse cursor, except that now you want to display something to the screen. You could simulate this with your own image of a mousecursor moving to the button and clicking - I'm not certain how to actually take the cursor away from the user programmatically and move it where you want, but it shouldn't be terribly difficult I think.. but the only part you need to worry about is what it looks like on the screen. Otherwise just call whatever function you call when you catch the button-click, you don't actually need the mouse to click per se. I know I didn't answer everything but I hope I helped somewhat at least.

Hi,
I am writing a DLL(general purpose plugin) for winamp.In this I want to write the details of the song into a file whenever the song changes. I used FILE *fp=fopen(file,"w") to open a file but it is giving errors. How should I open a file to write into?

CString stmpfilename,sMyText;
tmpfilename = "C:\\my.txt";
sMyText = "Hello World\r\n";
CFile f;
if (f.Open(tmpfilename, CFile::modeCreate | CFile::modeWrite | CFile::shareDenyWrite))
{
f.Write(sMyText, sMyText.GetLength());
f.Close();
}

HI,
I tried CFile also.I wrote the same code and included afx.h.But it is giving errors.I included afx.h

What is the exact error you got? You probably need to catch file exceptions.
|
|
|
|
|
OK
This seems strange.
You said the you included afx.h
Try this please
#include <afx.h>
char* pFileName = "test.dat";
TRY
{
CFile f( pFileName, CFile::modeCreate | CFile::modeWrite );
}
CATCH( CFileException, e )
{
#ifdef _DEBUG
afxDump << "File could not be opened " << e->m_cause << "\n";
#endif
}
END_CATCH

Hi,
when I delete a listbox item it seams the top index is set to 0, is this a normal behaviour? Can I switch this off or is there any good workaround?
Thanks for help, Moak
Here is a little MFC code snippet to produce the effect:
<br />
BOOL CTest1Dlg::OnInitDialog()<br />
{<br />
CDialog::OnInitDialog();<br />
<br />
for(int t=1;t<20;++t)
{<br />
CString sText;<br />
sText.Format("listbox line %d", t);<br />
m_list.AddString(sText);<br />
}<br />
m_list.SendMessage(WM_VSCROLL, SB_BOTTOM, NULL);
<br />
return TRUE;<br />
}<br />
<br />
void CTest1Dlg::OnButton1() <br />
{<br />
m_list.DeleteString(0);
<br />
}<br />
|
|
|
|
|
void CYourApp::OnDelete()
{
CString tmp;
int nCurItem = m_ctrlMainList.GetCurSel();
m_ctrlMainList.GetText(nCurItem,tmp);
if (nCurItem != LB_ERR)
m_ctrlMainList.DeleteString(nCurItem);
UpdateData(FALSE);
}
Call it and see if the abhorant behavior continues.

use code as:
int iSel=m_list.GetCurSel();
//delete
m_list.SetCurSel(iSel);
includeh10
|
|
|
|
|
doesn't work all the time, it requires a selected item.

includeh10 wrote:
int iSel=m_list.GetCurSel();

how about this...
int nIndex=m_list.GetTopIndex();
m_list.DeleteString(0);
m_list.SetTopIndex(nIndex);
It will work also without selection (Sorry, BaldwinMartin I didn't understand your code). Do I really have to do this... why does deleting an item changes the position, is that a known bad Win32 behaviour?
Thanks again

Some dialogs have new Windows XP
style - I maen buttons are not only simple
grey rectangle but they look better.
(as draw) or combo box has selection
button as blue rect and so on.
But when I am creating my dialog based
applications (in VC++ 7.1)
it still looks as Windows 98 or so on
even they run under Windows XP.
Is here any way how to turn of
this style for my application?
Thank you

I assmume that what you are asking is how to enable Windows XP Visual Styles for your application, so that you dialog window is drawn in the current theme.
You will need to add a Common Controls Manifest to your application, this is a script written in XML that forces your application to use version 6.00 of the ComCtl32.dll to draw the controls and non-client areas of your windows.
This manifest can be embedded in your exe file's resources, or you can place it in the same directory as your exe file and give it the same name as your exe file with .manifest appended to the end. For example, if your exe is called MyApp.exe then you would call you manifest file MyApp.exe.manifest.

Hope this helps,

My C++ editor is painfully slow on a large file (13 000 lines) whenever I add a new line. Does anybody know something I can turn in or off so it would be usable?
Thanks for any advice (oh apart from breaking up the file!)

Is there other problems with the machine (no more disk space, etc.)?
|
|
|
|
|
I am afraid not... space on hard drives and below physical memory capacity...
|
|
|
|

1) Are you using visual assist, or any other pluggings? See if you can turn'em off improve performance...
Another option is to delete *.ncb, *.opt, *.clw... If *.opt is corrupt vc editing will be very slow.

Deleted the opt and it worked! Thanks a lot! I am very grateful!
