1. How to create the balloon tooltip?
2. Why I can't change the size of the tooltip font on WinXP (on Win98SE - OK)

CToolTipCtrl m_Tooltip;
CFont font;

font.CreateFont(<code>12</code>, 0, 0, 0, FW_NORMAL, 0, 0, 0, DEFAULT_CHARSET,
                OUT_DEFAULT_PRECIS, CLIP_DEFAULT_PRECIS, DEFAULT_QUALITY,
                FIXED_PITCH, "Courier");
m_Tooltip.SetFont(&font);

Best regards,

Regarding (2): 'font' - what kind of variable it is? Local, global, member?

Of cause, font is a global member, declared in the header file.

I'm glad to hear you, Tomasz. Thank you for your help with tooltip.

Changing font works for me. The code you've posted caused the tooltip to switch to ugly, monospaced Courier font. Smile | :)

You may check if you don't have both global and local variables with the same name.

Yes it turns in ugly Courier, but not this main thing. A problem that at various height of a font on WinXP the font tooltip remains constant though on Win98SE his size varies. Any ideas?!

I'm not sure what do you mean exactly. I've tested this on XP with few different font sizes, and everything works OK - the tooltip font changes.

I have once again rechecked and have noticed, that the font does not vary at the size from 1 up to 16. After 16 size increases.

This problem with "Courier" font only. When the font is "Verdana" or other, then size changed is right.

Thank you.

Question (1): you need to use TTS_BALLOON style. If you don't have most recent Platform SDK installed, just add this define somewhere:

#ifndef TTS_BALLOON
#define TTS_BALLOON 64
#endif

Help button and propertysheet 2

19-Aug-02 4:15

Perfectly works!!!
But why appearance of the tooltip different if to create the following ways?

m_pToolTip.Create(this, TTS_BALLOON);

and

m_pToolTip.Create(this);
m_pToolTip.ModifyStyle(0, TTS_BALLOON);

I have a dialog based application that has some propertysheet.I wanted to hide Help button in it so as Shog9 said I put this statement in OnInitDialog ofmy application:

GetDlgItem(IDHELP)->ShowWindow(SW_HIDE);

But unhandled error happend and it seems that no window with this ID exist.I even put it in OnInitDialog of propertysheets but the same things happend.So how can I hide that help button?

This line of code will only work in the OnInitDialog() of your CPropertySheet derived class. If you don't have one of these, you can place it in the OnInitDialog() of the first page that you add to your CPropertySheet.

BOOL CMyPage1::OnInitDialog()
{
CPropertyPage::OnInitDialog();
GetParent()->GetDlgItem(IDHELP)->ShowWindow(SW_HIDE);
// ...
}

Pausing a timer

Is it possible to pause a timer created with SetTimer without actually killing it?

Michel

It is a lovely language, but it takes a very long time to say anything in it, because we do not say anything in it, unless it is worth taking a very long time to say, and to listen to.

I don't think so. You could set a flag which tells the timer function to ignore calls to it temporarilly, however killing and recreating the timer would probably be a better way to handle this.

Maybe you can use Sleep() somewhere in your code.If you use WM_TIMER you can use it to do some pausing.

Compiler Error!!

Hi, I am in the process of writing a Microsoft DirectShow filter tolay back vedio from a SGI server. The Directshow environment requires the "_stdcall" calling convention while the SGI requires the "_cdecl" calling convention. How do I resolve this error. One of the errors I get when having the _stdcall convention is
asyncflt.obj : error LNK2001: unresolved external symbol "__declspec(dllimport) public: static class MBMovieLib::Movie * __stdcall MBMovieLib::open(char const *,char const *,class MBMovieLib::StreamSpec *,unsigned long,class MBStreamDefs::NameValuePairs

Any help in resolving this problem will be greatly appriciated as I have been trying different things for about a month now.

Thank you.

Is that MBMovieLib::open class function in one of your own classes or in the third-party library? Did you declare it somehwere else as beeing _cdecl?

Why does VC++ 6.0 linker report this?

WREY18-Aug-02 13:12

WREY

18-Aug-02 13:12

The program compiles fine. It's when it reaches the linkage stage that VC++ 6.0 linker reports the reason it cannot do the linkage is because it, "Cannot open Debug/MySampleApp.exe for writing" even though the file is not opened or being used somewhere else (or any of those things).

If I were to use Windows Explorer and go to the directory (etc.) where the file is located and delete it, then go back and recompile it, everything would go through fine. No problem!

Does anybody know why this happens? This is not the first time the compiler has done this. It seems almost something at random.

Is there something in Project->Settings->Link I should set or change to prevent this?

Confused | :confused:

Thanks.

Check if the file is made read-only, for whatever reason.

Good suggestion! But if that was the case, then every time I do a compile and link, the same situation would occur; that's not happening. It's like a random thing.

If you are running Win9x/ME and the .EXE wasn't closed normally then this can happen. It typically happens if VC++ crashes. You need to restart Windows to get things back to normal. This doesn't apply to W2K/XP.

Would you know, it's Win2K that I'm using! Smile | :)

FWIW, Win2K is about the most stable platform MS has ever produced, which is why I don't suspect an OS issue here.

OTOH, I've been using VC++ from it was version 1, and have continued with it throughout the different versions to where I am, currently. It's only because of a very bad experience I had with XP that has caused me to freeze installing anything beyond what I already have (VC++ 6.0 SP5, and W2K SP2) and wait for any new product from MS to be out on the market for at least 3 years before I install a version upgrade.

With regards to the problem I'm reporting, it seems almost like a random thing because it is NOT every time the situation occurs (which is what makes it tough).

I also appreciate your NOT advising me to call MS about the problem. Doing that would only exacerbate the situation. Besides, I don't have time to waste and money to give away at the same time, ending up with NOTHING worthwhile!!!!!
