AFAIK you cannot do than. However, you may add a counter field to the table and then use it to order data when querying.

Compiler Design in C

DarkSorrow3815-Sep-09 19:05

I have compiler design in C practicals and i have encountered a problem. This goes as :
We have to take n number of productions(string) from user.
Each production is of different size.
I want the array size for each production to be dynamic with exact size as that of the entered string. There should not be any blank elements in array as it would spoil the output.
How this can be achieved. I am someone who not so good in C.

You could create an array of pointers if you know the value of n at compile time.

char *strings[50];

Now as you save each string to this array allocate the size.

strings[count] = malloc(sizeof(string) + 1);
strcpy(strings[count], string);

If the value of n is not known at compile time, create a pointer to a pointer.

char **strings;

When you get the value of n, allocate the array.

*strings = malloc(sizeof(char*) * n);

Allocation for each string is the same as above.
Don't forget to increment the count variable after to store every string.

1 Create a memory DC( CreateCompatibleDC )
2 Select the bitmap to that dc ( memdc.SelectObject )
3 Draw your lines/shapes to that DC.
4 Unselect the bitmap from dc.

Now your original bitmap will be having the drawings...

Hi naveen

Thanks for your replay .. i tried

HDC pDC=::GetDC(0);
		HDC TmpDC=CreateCompatibleDC(pDC);
		CImage _image;
		_image.Load(_T("//read.tif"));
		//HGDIOBJ hgdiobj = SelectObject(TmpDC,(HGDIOBJ)_image);
		CRect Recto(20, 20, 20, 20);
		int width=_image.GetWidth();
		int height=_image.GetHeight();

		HDC dcBmp=CreateCompatibleDC(TmpDC);		
		HGDIOBJ TmpObj2 = SelectObject(dcBmp,(HGDIOBJ)_image);		
		BitBlt(TmpDC,0,0,width,height,dcBmp,0,0,SRCCOPY);
		SelectObject(TmpDC,TmpObj2);
		
		DeleteDC(dcBmp);

but its not showing the rectangles in image ..??

plz reply

You could try changing the line
SelectObject(dcBmp,(HGDIOBJ)_image);
with
SelectObject(dcBmp,(HGDIOBJ)(HBITMAP)_image);

Check are return values for errors.
There was probably some error encountered at Load or one of earlier functions called.

you said you want to draw some lines and shapes. But the above code is not doing any of that.

HDC dcBmp=CreateCompatibleDC(TmpDC); HGDIOBJ TmpObj2 = SelectObject(dcBmp,(HGDIOBJ)_image); BitBlt(TmpDC,0,0,width,height,dcBmp,0,0,SRCCOPY);

What the above code does is copy the image in dcBmp to TmpDC. The dcBmp has your image, but the target dc TmpDC doesnt have any bitmap selected into it. So basically that BitBlt function does nothing. To have a valid image in the TempDC, you have to select one bitmap to that dc. Check the below code(especially the one in the bold ). The hBmp conatins the final image.

HDC dcBmp=CreateCompatibleDC(pDC);
HBITMAP hBmp = CreateCompatibleBitmap(pDC, 20,20);
HGDIOBJ OldBmp = SelectObject(TmpDC,(HGDIOBJ)hBmp);
HGDIOBJ TmpObj2 = SelectObject(dcBmp,(HGDIOBJ)_image);
BitBlt(TmpDC,0,0,width,height,dcBmp,0,0,SRCCOPY);
SelectObject(dcBmp,TmpObj2);
SelectObject(TmpDC,OldBmp);

		//HGDIOBJ hgdiobj = SelectObject(TmpDC,(HGDIOBJ)_image);
		
		int width=_image.GetWidth();
		int height=_image.GetHeight();
		
		HDC dcBmp=CreateCompatibleDC(pDC);
		HBITMAP hBmp = CreateCompatibleBitmap(pDC, 20,20);
		HGDIOBJ OldBmp = SelectObject(TmpDC,(HGDIOBJ)hBmp);

Where is the code to draw a rectangle?

rajugis wrote:
//HGDIOBJ hgdiobj = SelectObject(TmpDC,(HGDIOBJ)_image);

Why did you comment it? Also correct this line as SuperMan mentioned.
HGDIOBJ hgdiobj = SelectObject(TmpDC,(HGDIOBJ)(HBITMAP)_image);

try the below code. If everthing goes fine, it will draw a rectangle on the top left portion of the image;

HDC pDC=::GetDC(0);
HDC TmpDC=CreateCompatibleDC(pDC);
CImage _image;
_image.Load(_T("//read.tif"));
int width=_image.GetWidth();
int height=_image.GetHeight();
HGDIOBJ TmpObj2 = SelectObject(TmpDC,(HGDIOBJ)(HBITMAP)_image);			
Rectangle(TmpDC, 0,0, width/2, height/2 );
SelectObject(TmpDC,TmpObj2);
ReleaseDC(pDC);
