Seems DDX/DDV is not supported natively by CDialogBars, but Sharad Kelkar provides an extension to this purpose in his article CDialogBarEx : A Dialog bar with initialization[^].

You want to develop application VC++. Plz clarify what is your expected target of development platform i.e whether .NET or traditional manner ??

If you are interested in Arabic only then Unicode can be a good solution. Unicode supports almost all the Arabic characters. You can find some Unicode related articles here at Codeproject or at Codeguru.

As far as Urdu is concerned, then Unicode is not a good solution. Many Urdu characters are missing. However, since your requirements are low as you only want to display text on menus e.t.c, then you can use Unicode. But if you want to develop full fledge urdu text application, then you have to design fonts yourself.

If it is only the menu and buttons you wish to change then you could use owner drawn menus and buttons and have the text as bitmaps.

Check out:

http://www.codeproject.com/menu/menuxp.asp
http://www.codeproject.com/menu/bcmenu.asp
for owner drawn menus and

http://www.codeproject.com/buttonctrl/cbuttonst.asp
for buttons.

If you want the whole text then I guess you would need to develop your own fonts.

Good luck!!

acmStreamOpen returns MMSYSERR_INVALPARAM when I try to use it. All help appreciated.

I have an app where I want to convert audio from one format (PCM WAVE) to another. I've looked at the MSDN and I found out that you should first call acmStreamOpen. I've made a dialog that enumerates all the avaiable drivers, so you can select which driver you want to use for converting. But when acmStreamOpen is called, it returns MSYSERR_INVALPARAM which means "At least one parameter is invalid.". Here's my code:

void OnConvert()
{
	ACMFORMATDETAILS formatdetails;
	ACMDRIVERDETAILS driverdetails;
	HACMSTREAM hConvert;
	HACMDRIVER hAcm;
	WAVEFORMATEX wSource;
	WAVEFORMATEX wTarget;
	int res;
	DWORD cbwfx;
	
	acmDriverOpen(&hAcm, hCurrentDriver, 0);

	memset(&wSource, 0, sizeof wSource);
	memset(&wTarget, 0, sizeof wTarget);
	acmMetrics((HACMOBJ)hAcm, ACM_METRIC_MAX_SIZE_FORMAT, &cbwfx);

	wSource.wFormatTag = WAVE_FORMAT_PCM;
	wSource.nChannels = 2;
	wSource.nSamplesPerSec = 44100;
	wSource.nAvgBytesPerSec = 176400;
	wSource.nBlockAlign = 4;
	wSource.wBitsPerSample = 16;
	wSource.cbSize = 0; //sizeof(wSource);

	wTarget.wFormatTag = 85; //Lame MP3
	wTarget.nChannels = 2;
	wTarget.nSamplesPerSec = 44100;
	wTarget.nAvgBytesPerSec = 176400;
	wTarget.nBlockAlign = 4;
	wTarget.wBitsPerSample = 16;
	wTarget.cbSize = cbwfx - sizeof(WAVEFORMATEX);


	res = acmStreamOpen(&hConvert, hAcm, &wSource, &wTarget, NULL, 0L, 0L, ACM_STREAMOPENF_NONREALTIME | CALLBACK_FUNCTION); //Returns MMSYSERR_INVALPARAM
}

The hCurrentDriver variable is a HACMDRIVERID which contains the desired driver to be used for conversion. The acmDriverOpen returns 0 so nothing should be wrong there. Anyone know what could be wrong? I've been troubling with this for quite some time now.

All help appreciated.

Zlib and SelfExtactor, size problem?!

PinkPanter8-Sep-02 4:17

I made a sample 1 byte long file into a zipped SelfExtracting one; the resulting .exe file was less than 12 KB. It means that Decompression unit plus Exe header occupied 12KB.

When I use messy ZLib library I cannot get same result even by optimization techniques such as:

#pragma optimize("gsy",on)<br />
#pragma comment(linker,"RELEASE")<br />
#pragma comment(linker,"merge:.text=.data")<br />
#pragma comment(linker,"/merge:.reloc=.data")<br />
#pragma comment(linker,"/FILEALIGN:0x200")<br />
#pragma comment(lib, "msvcrt.lib") !!!! (link Dynamically to msvcrt.dll)

I've used VC6.0 and ZLib1.1.4 .

The size I gain is always more than 27KB plus GUI resources.
As another way if you build a tiny dll and export "compress2" and "uncompress" functions, the minimum Dll size will be 35.5KB (the minimum possible dll size is 2.5 KB).
I know that some venial difference rise from compilers and systems, but this gap is something else (as I guess.)

How can I extract a tiny simple compression/decompression unit from such libraries (Zlib or Rar)?
Is there any source code available who present a simple and tiny Comp./Decomp. method?
What's wrong with my Dll?

maybe you could try the ZipArchive library which presents a wrapper around the zlib as far as I know and gives great power easily. It can make self-extracting archives and is easy to use, and I'm not advertising it, I just found it good and easy when I used it.

If you search through the articles here at code project you can find an article about it and a link.

Hope it helps and makes your life easier Big Grin | :-D

Have you tried removing the WS_EX_APPWINDOW style from your window. Otherwise you can add the WS_EX_TOOLWINDOW to your window. The only drawback to making your window a tool window is that you will get the mini-caption bar instead of the regular caption bar.

I want to export some information from my software into Word.

I am not able to use the OLE for Word. Can somebody help me ? How can i initialize a word document and then write my data in it.

I want to use tables while exporting the data.

Is there any article which tells me to do that ?

I am not using MFC. I am constrained to use only Win32 APIs

Thanks in advance

CTabCtrl and CDialog

I created several CDialog with CreateIndirect calls. The dialogs are of style WS_CHILD|WS_VISIBLE|DS_FONT. They are created fine, but say, in my tab, it has 3 pages (3 dialogs), the 3rd dialog is covering the 2nd dialog, which is covering the 1st dialog ?

How can I hide the inactive dialog ???
I don't find any SetVisible() method in CDialog.

Thanks

Thanks very much, but i have another problem in changing showing and hiding the dialogs.

When a tab is selected, it's refected notification TCN_SELCHANGE, so i handle it to make the selected dialog visible.

The header is like this, but i don't know how to get the information about selected tab.

I tried to write:

void CTabPageView::OnTcnSelchange(NMHDR *pNMHDR, LRESULT *pResult)
{
	TCITEM pitem;

	int cursel = GetCurSel();
	if (cursel != -1)
	{
		GetItem(cursel, &pitem);
		UINT dlgId = pitem.lParam;

		//something ...
	}
}

However, in this case, i got the lParam of 0 instead of the stuff i put in before for creating the tabs.

GetItem() only works if you have set the correct mask in the TCITEM structure.

eg. to get back the lParam you must set:

pitem.mask = TCIF_LPARAM;

I made a class in VC++. This class is derived from some MFC class. e.g: class myclass:public CDialog.

Now i want to use the objects of myclass in various applications. I also want to derive new classes from myclass and implementing its virtual functions in derived classes e.t.c

But i want to reuse this class in my Visual Basic applications. Is it possible ??? What kind of DLL i need to make ??? Is it possible using COM ??? Or what else the solution ???

Is it guaranteed that such ATL compopnent will be used easily by VB because, I am deriving my class from MFC class, CSocket ??
Secondly, instead of using ATL approach , if use COM hardcore approach. Then will there be any difference using COM or ATL ???

Yes, if you don;t use ATL, it will take you longer.

Any ATL component will work with VB.

Thanks alot Smile | :)
