Did you make sure that the case of the HREF matches the case of the actual pages on the Apache server?

Hi,

What do you mean by the actual pages on the Apache server? Do you mean the HREF on my pages have to be all lower case or upper case?

If you page name is H1.htm and your link is a=href"h1.htm", this will not work on all Apache installactions.

Hi,

Sorry I forgot to mention. The page (1a.htm) has a submit button. When clicked I use Javascript something like this;

where
onDone()

Debugging From Win2K to Win98

I have a few issues that I was wondering if anybody has seen before or pointers to help out with.

First I am developing an application in Windows 2000 Professional that is supposed to be supported in all varieties of windows. I have run in to several issues where even though it runs in 2000, it fails in 98. A classic example was a divide by zero error in 98 was not even reported in 2000. I have tried to convince my "small" 4 person R&D company to help me setup a win98 test system. They are balking, so I brought in my own system from home with my home development system on it. However the first issue is that when I tried to build on it, it seems to always die on the pre or post build steps. (i.e. I have a kernel library for products that I created that a post build step copies it to a known directory, my home system dies when I try to do this.) The beginning of the main project has some text that says it is "Copying Contents file" which my 98 system cannot get by. The system is Windows 98 First Edition (I know get a better OS but it also has Linux on it) with VC6 SP5 (same as the 2000 machine.) Anyone seen and fixed this behavior before?

So my next question is: Are there any other things that Windows 2000 will hide that cause crashes in Win98 that I can look for? I have searched for an article, but I could not find one in the minimal search that I did. It is going to be hard to fin without a 98 debug station....

Thanks,
Brian

i ran into some issues with CBrush::CreatePatternBrush that win2k handled but win98 failed on (fatally, took down the OS). it happens when you create a brush that's larger than 16x16 (i think, maybe even 8x8). the docs mention the limit, but they don't mention that you can kill the OS with it.

This doesn't help you but you might be interested to know that there is a product out there that allows you to run multiple operating systems simultaneously instead of having to bring in separate machine (H/W)for each OS you want to test on. It is called Virtual PC from Connectix Corp. I use it and like it very much. However, it will not always work correctly for testing DirectX applications.

Click-through-able window

I want to create a special kind of status window. A transparent window just floating somewhere on the desktop, and I want all mouseclicks to somehow be directed to the window below. In my case I only want the X in the corner to be possible to click. I know this is possible, but I can't figure it out myself.

This is taken from the feature list of another app:
"Transparent - You can make the desktop preview windows transparent in the form of click-through-able. This means that when you click on a desktop preview window, you're not actually clicking on the desktop preview window, but on the window under it. The only place you can click the preview window is on the header."

Seems like returning HTTRANSPARENT to the WM_NCHITTEST message would do the trick (haven't tried myself).

Hi there

I want to increase and decrease the volume of a wave file inside the wave file, thus not using any waveOutSetVolume type of functions. The simple logic is propably to multiply each wave bit by a constant, but how can this be done.

Thank you

Trying to use the afx.h MFC extensions to simply create a file pointer (dvs. CFile* pFile = new CFile();) then later serialize an object to disk. Throw in the necessary MFC library directory via the LIBPATH (C:\Program\MICROS~2\VC98\MFC\Lib) link option.

Heard something about using dynamic binding to fix the unresolved errors?

how to update StatusBar?

Anonymous3-Sep-02 0:52

Howdy!

I've managed to build a status bar and I can assign it a
value when the application starts, but how can I update it while
the application is running?

In the CMainFrame::OnCreate I can use
m_wndStatusBar.GetStatusBarCtrl() to get the address of
the StatusBarCtrl, but how could I get it outside CMainFrame class?

If you want to set the text in leftmost part of status bar, use CFrameWnd::SetMessageText. For other statusbar panes, use normal ON_UPDATE_CMD_UI mechanism.

uh-oh... I'm a newbie.

What I meant is that from a CDocument class function I
want to change the status bar first pane text.

How can I write status bar from there?
I don't have inside CDOcument class the address of the CFrameWnd
class object to use CFrameWnd::SetMessageText.

Re: how to update StatusBar?

Tomasz Sowinski3-Sep-02 2:45

Tomasz Sowinski

Use this:

static_cast<CFrameWnd *>(AfxGetMainWnd())->SetMessageText("I'm on status bar now");

Keep in mind that this changes the status bar text until next idle update UI cycle is executed. Do you want to change this text permantently?

Still baffled...

I added the code, no effect.

I want to show on the status bar when the data was last time
saved successfully. Now it just shows the date & time once,
when CFrameWnd is created. CDocument object function
should be able to update the information permanently.

Instead of standard 'Ready' message, right? If this is the case, override CFrameWnd::GetMessageString:

void CMainFrame::GetMessageString(UINT nID, CString & rMessage) const
{
if (AFX_IDS_IDLEMESSAGE == nID)
{
rMessage = "I'm on status bar";
return;
}

CMDIFrameWnd::GetMessageString(nID, rMessage);
}

I take that you're able to create a status bar in MainFrame (including setting pane # and size). Once outside of MainFrame, youneed to get a pointer to it to modify the status bar remotely.

#include "MainFrm.h"//or equivalent .h
.
.
.
CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;//pointer to mainframe object
.
.
.
pFrame->UpdateStatus(1, "1st panel message...");//and so on

SOLVED!!

Aaaahh... I'm a moron (but not moron enough not to write under anonymous Wink | ;-)

1st: status bar has this default feature to show "ready" or tooltip on it. I forgot that.
I had made my own simple status bar, and I mixed on the way SetMessageText
and SetPaneText.

2nd: I couldn't get my hands on the CMainFrame object. Thanks to the
replies, now I could!

3rd: (back to the being stupid) When I was instructed to use pFrame->UpdateStatus(1, "1st panel message...")
I was just baffled ".. but there is no UpdateStatus in CFrameWnd class..." Smile | :)

Ok, here is how it works now, in case this helps someone else. I am NOT
updating the default message text on the status bar, I have created my own
pane with a text:

in MainFrm.h must be lines
public:
void UpdateStatusBar(CString sMessage = "");

- - - - - -

int CMainFrame::OnCreate(LPCREATESTRUCT lpCreateStruct)
{
if (CFrameWnd::OnCreate(lpCreateStruct) == -1)
return -1;

if (!m_wndStatusBar.Create(this) ||
!m_wndStatusBar.SetIndicators(indicators,
sizeof(indicators)/sizeof(UINT)))
{
TRACE0("Failed to create status bar\n");
return -1; // fail to create
}

UpdateStatusBar();

return 0;
}

- - - - - -

void CMainFrame::UpdateStatusBar(CString sMessage)
{
CWinApp* pApp = AfxGetApp();

// the values are read from the registry
CString strValue, strValue2;
strValue = pApp->GetProfileString("Latest update","Date");
strValue2 = pApp->GetProfileString("Latest update","State");

if (strValue.IsEmpty()) {
m_sPaneText = "Data saved: n/a"; }
else {
m_sPaneText.Format("Data saved: %s, %s", strValue, strValue2); }

CStatusBarCtrl &stCtrl = m_wndStatusBar.GetStatusBarCtrl();

// Let's keep it simple...
stCtrl.SetSimple();

// in case you want send a different message to the status bar
// m_sPaneText is a member of CMainFrame
if (sMessage.IsEmpty())
stCtrl.SetText(m_sPaneText,255,0);
else
stCtrl.SetText(sMessage,255,0);

}

- - - - - -
...and then at the same in another class...

In AppDoc.cpp must be line
#include "MainFrm.h"

- - - - - -

void CAppDoc::SaveDataToServer()
{
// blah blah blah... save data and other dull jobs...
// in my case write to registry. The values are read in
// UpdateStatusBar later on and displayed.

// update the status bar from CDocument class object
CMainFrame* pFrame = (CMainFrame*)AfxGetApp()->m_pMainWnd;//pointer to mainframe object
pFrame->UpdateStatusBar();

return;
}

Thanks,
