Hi, I am facing a strange font problem

<br />
Font Name : Aparajita<br />
Language  : Hindi<br />
<br />
Platform : C++ Win32 (NO MFC)

I created a dialog with a simple edit control.
When i enter the path displayed below in the edit control,
Everything is displayed in correct size,
But only the hindi text is displayed very small. Just unreadable.

Path Entered: C:\Hello World\सरकारी\Files

I have tested this with Chinese Font. It is ok.
How to over come this problem. Please help. Confused | :confused:

Thanx 4 everyone, problem solved.

Regards,
Vishal

1) Is Aparajita is Hindi font and
2) Is सरकारी is unicode string or ascii string?
If it is unicode than you must choose the font as Mangal and than check.

Unicode String

Checked with Mangal. The result is same.

Actually the string contains both english and hindi. Dead | X|

I am facing this problem with Bengali and Oriya only but not in Hindi. Please check that you have Mangal font installed in your system?
It should be in SystemDrive:\Windows\Fonts folder. One more thing that I do is copy the font of mangal in Windows 7 or Vista and installed it in your pc. Might be your problem is resolved.

Hi Alok ji,
Please ask this question to Vishal Smile | :)

.

BTW the string is Unicode than there is no need to set the Hindi font. He can set Mangal instead.

some times it's project requirement to use some particular fonts and never depend on UNICODE based on size and shape they take Smile | :)

Yae but for English and Unicode font, I don't think so that it is being used.
For an example if I have English string might be "abcd" and I set some Hindi font. If any shape is mapped in that Hindi font than it might be a hindi value without meaning. So for English font we have to take care of it.
Example :
In some Hindi font "a is mapped with shape क" and in some other font may be "a is mapped with shape अ".

Aprajita Font maximum size is 72. I had tried Mangal Font also, but no success.

It means that your font is in font folder. Right.
Now open Winword and write the path that you want to show in edit control and select all and set the font Mangal and check it is same as displayed in your edit control. If yes than try to check with different size.
Or copy the Mangal font from vista and windows 7 machine. New version of Mangal font looking nice.May be your problem is resolved by installing it in your system.

YES.

It is ok with winword. But not with Edit Control. I am on Windows 7.

So, got no idea why this is not working but it simply not working.

    SIZE_T BASE_BUFFER_SIZE = 512;

BYTE * bInitialBuffer = NULL;
bInitialBuffer = (BYTE *)VirtualAlloc(0,
        BASE_BUFFER_SIZE, MEM_RESERVE, PAGE_READWRITE);

if(bInitialBuffer == NULL)
{
    // handle this
    TRACE("VirtualAlloc failed!");
    return NULL;
}
DWORD dwReadBytes;
while (FALSE != ReadFile(hDevice, bInitialBuffer, BASE_BUFFER_SIZE,
    (LPDWORD)&dwReadBytes, 0) && dwReadBytes > 0)
{
    TRACE1("got buffer! %d",dwReadBytes );
    }
    if(dwReadBytes <= 0) TRACE("failed!");

GetLAstError() returns Invalid access to memory location.
I am dealing with virtual alloc for a first time :P
What am i doing wrong?
Thanks

Just a hunch. The doc says that MEM_RESERVE flag Reserves a range of the process's virtual address space without allocating any actual physical storage in memory or in the paging file on disk.

If you're actually going to do something with the memory, MEM_COMMIT may be a good option (you could combine flags, like MEM_RESERVE | MEM_COMMIT). At least the doc[^] says so.

You also failed to tell what's "not working". I'm assuming that your ReadFile call failed, and GetLastError returns invalid access to memory location. Reading that, I'm assuming that since you're just reserving memory with your VirtualAlloc call, and not committing it before using, you're getting an invalid access error.

Yep, you are right. But here with this stuff i got more and more problems. For example, i cannot return bytes from function, (this code is a function, which should read a file into BYTE array and return this array among with nr of bytes read).

BYTE *ReadBytes(HANDLE hDevice, LPDWORD lpdwBytesRead)
{
	SIZE_T BASE_BUFFER_SIZE = 512;

	BYTE * bInitialBuffer = NULL;
	bInitialBuffer = (BYTE *)VirtualAlloc(0, 
			BASE_BUFFER_SIZE, MEM_COMMIT | MEM_RESERVE, PAGE_READWRITE);

	if(bInitialBuffer == NULL)
	{
		// handle this sh*t
		TRACE("VirtualAlloc failed!");
		return NULL;
	}
	DWORD dwReadBytes;
	while (FALSE != ReadFile(hDevice, bInitialBuffer, BASE_BUFFER_SIZE, 
		(LPDWORD)&dwReadBytes, 0) && dwReadBytes > 0)
	{
		TRACE1("got some buffer! %d", dwReadBytes);
		lpdwBytesRead += dwReadBytes;
	}
	return bInitialBuffer;
}

and if i call it:

DWORD read = 0;
BYTE *DataBuffer = ReadBytes(hFile, &read);

read is always zero, and i got no bytes returned from function... And i cannot use just defined size (skip memory allocation).
Help ;(

One step at a time. Have you progressed from your previous error, or not? With the MEM_RESERVE flag, do you still get an invalid access error while calling ReadFile?
