I suspect you'll need to install MDAC regardless.

OK, I'll wave my magic wand and install MDAC on every W98 machine on the planet. Done.

You can't do it, I can't help you or change that. You'll need MDAC. End of story.

I have a server and a client app. I want to send some data from server to client without a request from client. How could the client get the data from server with only a event ?
I know I can get if the server use PostMessage function, but only using a wparam (16 bits) and lparam (32 bits).

Thanks,
Cristiano.

Basic window style question(non-MFC)

oztanharmanci5-Aug-02 8:29

Hi. My problem is this:
I create a window using CreateWindowEx(). Then I create other windows[tool windows, document window etc...] All these are in non-MFC. The problem is that, if the user clicks on one of the tool windows, the mother window and all others lose focus[The title bars of those windows become gray]. And similarly if any window is clicked all others lose focus. I hear you saying "so what?". Here is the problem: When I start a DialogBox() only the spawning window is blocked, other windows are not. But I want them all blocked until the DialogBox returns.

I tried an MDI program generated by Visual C++ 6.0's wizard. What I want is exactly that(all windows titles are always highlighted!) but in a non-MFC way.

I tried different combinations of OVERLAPPED, CHILD, POPUP etc. but couldnt get it right. Can anybody help me?

Thanks
Oztan

PS: By the way I think being highlighted is my problem that is why I am talking about it. Actually I dont care which windows are highlighted and which are not, I just want the DialogBox() to block them all.

I guess one way you may do this is:
1. Disable (or Hide) all child popup window (or dialog #32770) that existed. To do that, you
may call EnumChildWindows.

BOOL CALLBACK gfnEnumChildProc(HWND hWnd, LPARAM lParam)
{
	TCHAR szClass[CLASSNAME_LEN];
	::GetClassName(hWnd, szClass, sizeof(szClass)/sizeof(TCHAR));

	DWORD dwStyle = ::GetWindowLong(hWnd, GWL_STYLE);
	DWORD dwExStyle = ::GetWindowLong(hWnd, GWL_EXSTYLE);

	if (_tcsicmp(szClass, _T("#32770")) == 0)
	{
		// a child dialog of main window...
	}

	if (dwExStyle & WS_EX_TOOLWINDOW)
	{
		// a floating control, do not rely on class: Afx:000xxx..
	}
}

2. I just re-read your post and I think you could get away with it by creating your dialog inside
of your main window. or why is this not an option?

Hmm, your answer is more tricky than I expected.

"I think you could get away with it by creating your dialog inside
of your main window"

Ok. Here is the situation.
I have the main window.
Main window creates two toolwindows. [One is for document, other is for interfacing with user]
The interface tool starts a DialogBox. I want this dialog box to pause everything [stop user interaction between main window and the documetn toolwindow] But while the dialogbox is running I can still use the other tool and the main window! Only the dialog that spawned this dialog is paused.

I hope the problem is clearer now. I believe I can solve it with proper ownership and window styles but I just can't figure out which is the correct one.

Thanks

Yes, that's what I meant! Is there any reason why you can't create (start) this dialog
from the main window instead from the interface? Your interface is modeless and how you
create the DialogBox (which is modal) will affect only its parent. Can you post some code,
how you create your 'DialogBox' (constructor) before you call DoModal()?

question about _variant_t - not much info in MSDN

5-Aug-02 8:04

I need to know how I can retrieve data from my database if its stored as as bytes.

So far to get strings out I have been doing a _bstr_t cast to the value received from rs->fields->getItem->Value . However somewhere I read about

rs->fields->getItem->Value.iVal

and
rs->fields->getItem->Value.bVal
but cannot find any info on it.
Thanks for your help,

__variant_t derives from VARIANT. iVal, bVal, fltVal and others are defined in VARIANT stuct.

What is "scratch" and why can everything be made from it?

Look in MSDN. VARIANT is a union and can hold many types of data. In fact you can look here:

MP3 Header Information

Hello,

I'm trying to make a personal app. that will organize my MP3 collection in a particular way. Is there any code out there that can parse MP3 header tags to get the particular text fields (e.g., title, album, artist, etc.)?

Thanks!

if you're looking for ID3V1 tags... check out my article CMP3Info:

ID3V2 will be implemented in the not too distant future

Actually it is very easy to parse ID3V1 tags. Simply seek the file pointer of an mp3 file to the end minus 128 bytes. You can then read the 128 from this pointer until the EOF (End of file).
If the first three bytes equal "ID3" you know that there is an ID3V1 tag at the end.

However, I don't know how ID3V2 tags work Frown | :(

I wrote something a while ago that uses filenames for song names and folder names for artist and album. ID3V1 is a doddle, it's just sitting on the end of the mp3 ( which is why if you're *ahem* downloading an mp3 and don't get it all, there's no id3 info ). ID3V2 is compressed though, I used a class I found on the net ( and fixed, as I recall ) to do it. If you have no joy and want ID3V2, just LMK and I'll send you the class. I can't post it to CP as I did not actually originally write it.

Hi Christian,

I would love to get that ID3V2 class you spoke of! I always use V2, so V1 won't work for me. I don't plan on selling (or widely distributing) this application.

Thanks!!!

Re: CEdit Box -- select all contents

5-Aug-02 6:05

Hello,

When clicking on a CEdit box, I would like the entire contents of the box to be selected (so that the user can simply overwrite existing text instead of manually backspacing over the existing contents). I have searched and didn't find anything on MSDN help. When a user tabs to the CEdit box, the entire contents are selected--the exact behavior I want for a user mouse-click. Any suggestions?

Thanks!
