I think we have a little problem if he creates a font for editbox it will be work but if he runs his program on the a computer that has arabic language for OS so I think he will be problem.

1. Have you enabled this language on your computer at first place? (Internet explorer/FF has it inbuilt)
2. If 1 is done, then is your application Unicode?
3. If 2 is true, then what do you mean by your CEdit control did not accept Arabic?

Anything I will say you will bring it down to whatever you want.

1.What do you mean "enabled this language"?
I have add "Arabic language" & "Arabic input method" in "Console Panel->Regional Options". Is it OK?

2.How to see whether my application is unicode?

That's it. Now, are you able to type in Arabic language in notepad?

I am asking if you've done an ANSI build or an Unicode build of your application. What happens when you type Arabic in the application that you built? Do you see question marks to appear instead of Arabic?

I can type Arabic in notepad. But I can't type it in my application. When type Arabic, it displays nothing.

Again, does your application understand Unicode? Have you got _MBCS or _UNICODE defined in the preprocessor definition? See here if you don't understand what I am asking you about.

Now it really works. I can input Arabic in CEdit.

But it seems that VC6.0 doesn't support unicode input while coding. I can't input Arabic directly in the code.

Visual Studio.net will support unicode well.

Japanese character

Dear all,

I would like to display japanese character in my editbox, and the no of characters should be 32. that means its not 32 japanese characters. its 32 keyboard strokes. If a user enters 32 keyboard strokes, then the edit box shouldnt display the character which was pressed after 32.
Can anyone please help me on this?

Thanks in advance.

Regards,
Ram

It's been a long time since I did C++, but surely it should be easy to handle the event and maintain a character count? Of course, make sure to _reduce_ the count if the user hits Backspace/Del. Also, you shouldn't increase the count if a non-char key, like Ctrl or the arrow keys was pressed.

Also, pay attention to the paste operation!

Cheers,
Vıkram.

After all is said and done, much is said and little is done.

I was trying to catch the character by the onchangeeditbox() function. But if i press a char in keyboard it doesnt come to that function. after i press enter only it will go to that function. thats why i couldnt able to count the no of chars.

Hi,
I donot know whether u have tried this. CEdit::SetLimitText(32)

Ram Murali8-Jul-07 20:41

8-Jul-07 20:41

ya i tried this too. I set a limit to 32. may be let me explain a bit about japanese fonts using English keyboard. the OS will wait until a user presses enter to confirm the char. otherwise all the typed characters will be in buffer. So once i reach 32 charecters, i can still type characters without pressing enter. if i press enter, anything more than 32 chars will be truncated off.

Regards,
Ram

Normally, SetLimitText() will not allow more than the specified characters. It doesnot require pressing enter key. Iam not sure about japanese fonts. If SetlimitText doesnot work i thing u need to handle many windows events like WM_KEYDOWN, ...

As you earlier said that the control comes to onchangeeditbox() only when you press ENTER key, then let the control come to this function. Afterwards you can take the data of Edit box in some array and do the necessary manipulation in array i.e make the data 32 character long....and then display the data in this modified array in Edit box.

Hello and good day to all,
I am currently working on a project where I can patch together a number of bitmaps and make them as one. It also has options of resizing the bitmap before saving it by removing some bytes here and there. Because of the limitation in CreateCompatibleBitmap() on large files, what I do is I store the needed data on BITMAPINFOHEADER and BITMAPFILEHEADER and I also have a char * for saving the actual data of the bitmap.

Here is where the problem starts. I have a 3200 x 3200 and easily saves it on a bitmap, then I can also reload and resize and make it into half (1600 x 1600) then saves it and it works(I can see it in the explorer). However, when I resize it to a third of a size (1067 x 1067), the bitmap file (when opened in explorer) won't show and even load. But when I resize it to a fourth of the original size it shows. These problem also occurred on the one-sixth of the original.

	BmapFHeader.bfType	  = 'MB';<br />
	BmapFHeader.bfSize      = (gBitMap.width * gBitMap.height * 3) + 54;		<br />
	BmapFHeader.bfReserved1 = 0x00;<br />
	BmapFHeader.bfReserved2 = 0x00;<br />
	BmapFHeader.bfOffBits   = 54;<br />
<br />
	BmapIHeader.biSize	  = 40;<br />
	BmapIHeader.biWidth	  = gBitMap.width;<br />
	BmapIHeader.biHeight	  = gBitMap.height;<br />
	BmapIHeader.biPlanes	  = 1;				<br />
	BmapIHeader.biBitCount    = 24;	<br />
	BmapIHeader.biCompression = BI_RGB;<br />
	BmapIHeader.biSizeImage   = gBitMap.width * gBitMap.height * 3;<br />
	BmapIHeader.biXPelsPerMeter = 0x00;<br />
	BmapIHeader.biYPelsPerMeter = 0x00;<br />
	BmapIHeader.biClrUsed	    = 0x00;<br />
	BmapIHeader.biClrImportant  = 0x00;

Above is the BITMAPINFOHEADER and BITMAPFILEHEADER and I write it to the file, and afterwards I write the data. I double checked every parameter but all of them seems correct. Its just weird that it works on certain sizes while does not work on some. I am hoping that someone here might know the answer. Please help me out! Thank you very much!

Edit: Already solved! 24bitmaps that I am processing needs to have a row which is divisible by 4. Many thanks to Whitesky for the immediate attention and help, Naveen.R for the suggestions, and specially to Paresh Chitte for the great articles that solved my problem. Thanks also to the others for the time and effort!
