You maight read my answer this way:

You should elaborate: with the provided info we couldn't even guess what is happening with your application.

Fix your program! Your question is far too vague for anyone to give you a solution. You need to do some investigations for yourself to try and determine what is happening in your code, and what part of it is not working correctly. Then present the information you have found and people will try to help you.

You can use a 3rd party software like "Process Explorer", i think that can show the number of GDI handles a process uses, if you see this number showing an increasing amount then you are most likely leaking GDI handles. How you can find where is up to you, i don't know of any particular automatic method for that. If you do any drawing yourself somewhere in your application, that's your best bet.

If you have the source code for the application, try setting breakpoints to zero in on where the blackout is occurring. When you locate the exact statement that's doing it, it will probably tell you what the problem is.

Replace values

Hi all,
I am reading some values from command line and i want to replace them with other values.

Command line input ranges are from (50,51,52,........... 480,481,482)

I need to replace with (172,171,.....0,-1,-2,...-260)

Here is my code:

int main(int argn, char  **argv)
{
	char c;
	int h;
	double Pos[9];
	double pd[6];	
                 double test=51;
	printf("\nEnter position (val1, val2,val3,val4,val5,val6,val7,val8,val9):\n");
        
	for(h=0; h<9; h++)
		
	scanf("%lf",&Pos[h]);
		
	if(Pos[7]=="50")  
	   Pos[7]=172
                 if(Pos[7]=="51") 
	   Pos[7]=171;
	 if(Pos[7]=="52") 
	   Pos[7]=170; 	
	return 1;
}

Can someone help me how to do.
Thanks
Raj

I don't understand the details of your requirements, however for sure you must take advantage of the linear relationship between the input and the output range:

newValue = 222 - originalValue;

Your transformation law is

y = 222 - x

(y = 172 - (x-50))

Cannot you simply apply it to the input data?

Don't use doubles for integer values, it will only cause you problems. As stated by both Luc and Carlo, you have a simple calculation to do on each input value, you can then store or output the new values as required.

Loop in X to Y, where

X = first command line Value(Convered to Int)
Y = Last command line Value (Converted to Int)

output = Y - X - 260;

Apart from the fact that you could simplify the code as suggested by others, there are a number of immediate problems with this bit of code:

raju_shiva wrote:
if(Pos[7]=="50") Pos[7]=172

First, Pos[7] is a double - in C if you compare Pos[7] to "50", which is a null-terminated string not a numeric value, you will not get what you expect. That line should be:

if(Pos[7]==50)

Second, even with that change, it will almost certainly not work, because comparing floating-point value to an integer is unlikely ever to give a match. Change Pos to an array of integers instead.

Third, you are missing the terminating semi-colon at the end of the next line, which should be:

Pos[7]=172;

It's a bit (euphemism) tricky parsing a C++ file.
If you're lucky the source file you need to process use a small subset of the C++ language expressive power and then you may write down the parser without too much effort.
Parsing tools like bison[^], ANTLR[^] or the lua LPeg library[^] may greatly help you in the development.

Good luck.
