Vikas, if you have read all those things you should be able to solve the problem. Nobody here writes programs for you.

May I politely ask you to read forum posting guidelines [^]?

About your problem, what is your doubt about? Aren't you able to traverse the string? Aren't you able to differentiate among alphabetic character and numeric character?

Run a loop for the length of the string, check each character to find if it is an alphabet or a number. Invalidate, as per requirements. What have you done so far and where are you stuck?

If you are going for pure c program then

take the character array and check each character with the ASCII range.
say
ur char ch[350]

if( 48 >= ch[i] &&
57 <= ch[i] ) then it is numerical

if(( 65 >= ch[i] || 97 >= ch[i] ) &&
( 90 <= ch[i] || 122 <= ch[i] )
then it will be alphabets

Conversion of CBitmap into Array of BYTE and Vice Versa

There's also this...

#include <string>
using std::string;

string str1 = "abc123";

if(str1.find_first_of("0123456789") != string::npos)
{
     //String contains numeric characters.
}<pre>

Hi,
I had a simple client/server application that excahnges text data through array of bytes (BYTE byBuffer[256]). Now the server wants to transmit the image data (CBitmap) to the client. How the CBitmap object can be converted into array of bytes and then on receiving end (client) it can be converted back into CBitmap.

THANKS.

To get the CBitmap to byte use

GetBitmap( BITMAP* pBitMap ); refer http://msdn.microsoft.com/en-us/library/279a3c0c(VS.80).aspx[^]

of CBitmap where LPVOID bmBits member of BITMAP will having the byte array.

To set the BYTE array to CBitmap, you can use DWORD SetBitmapBits( DWORD dwCount, const void* lpBits ); you can set your byte array to lpBits.

I am facing problems with GetBitmap , however GetBitmapBits is giving me byte of array properly.( I guess). but I am unable to get the size of these bits for SetBitmapBits( DWORD dwCount, const void* lpBits ).

I tried with the way discussed in the article as well. Using GetBitmapBits and SetBitmapBits[^]

but it does not work.

There is no error but the output is not correct.

see the code below

CDeskTop desktop;

BITMAP bmpX,bmpY;
CBitmap mybmp,bmpClone;
DWORD dwValue,dwValue2;

mybmp.Attach(desktop.GetDeskTopImage());
mybmp.GetBitmap(&bmpX );

bmpClone.LoadBitmap(IDB_BITMAP1); // IDB_BITMAP1 bears the same co-ordinate as the source
int x=bmpX.bmHeight*bmpX.bmWidth;

BYTE* bmpBuffer=NULL;
bmpBuffer=(BYTE*)GlobalAlloc(GMEM_ZEROINIT,bmpX.bmWidth*bmpX.bmHeight);
dwValue=mybmp.GetBitmapBits(bmpX.bmWidth*bmpX.bmHeight,bmpBuffer);

dwValue2 = bmpClone.SetBitmapBits(bmpX.bmWidth*bmpX.bmHeight,bmpBuffer);
bmpClone.GetBitmap(&bmpY);

CDC memDC;
CClientDC dc(this);
memDC.CreateCompatibleDC(&dc);
memDC.SelectObject(&bmpClone );
dc.BitBlt(0, 0, bmpY.bmWidth, bmpY.bmHeight, &memDC, 0, 0,SRCCOPY);
DeleteDC(dc.m_hDC);
GlobalFree((HGLOBAL)bmpBuffer);

Figure out what is done in the C++ on the functionality front. Then you can implement the same in JAVA. I don't see much other than the oops concept being the same in either of the languages.
On another note, may I politely ask why do you need to convert the C++ code to Java code.

You cannot do a C++ to Java 'conversion' as such. Think of pointers, for instance. Period.

You wrote the program, right? So, you know what it does. Now, just rewrite it in Java.

C++ syntax can be converted (even most pointers), but the real challenge for you will be to find the equivalent underlying library functionality in the Java library.

Just a guess here but maybe you need to use the right font with the right charset to display your texts.If you check out the LOGFONT[^] structure and look at the lfCharSet member it can have the value of GB2312_CHARSET. That looks promising, does it not? Smile | :)
