Hello,

I am tryng to populate a combobox with characters like: + - " , ; etc..
But the problem is that every data must be separated by a semicolon and I need the semicolon to be also in my combo.

How can I prevent the program to skip my semicolon? is there any special character to put before or after the semicolon?

thnks for your kind help

So how are you adding the items to the control? Show a relevant code snippet, and what the output is.

I just use the properties box and input my charecters in the Data field as following:

?;",!;.;:;,:

Put each item on a separate line, not separated by a semicolon.

Yes. Do the two versions differ in this regard? If so, then just add the items at runtime.

\; ?

otherwise, the only solution is to populate programmaticaly in the OnInitDialog() function

algorithm :

while EOF not reached
    read line
    find the position of the ':' character
    extract from the current position, until the end of the line the characters
    eventually trim (left and right) the residual white space characters
    //there you have your value
end while

Google fstream, it's the header that contains the classes to do all of this. An ifstream is what you need.

Read each line of the file until you find one that begins with "IP Address: ", then take the remainder of that line.

A problem with loops

Hey guys,

I'm having a problem with a variable within a function. This variable is set to zero at the begging of the block, and used as an index for a few arrays. The ONLY place where it is changed is in the for(...; ...; Channel++) portion of the loop. Somehow this number is being set to -1. The range for this int 0 - 7. Any clues what could be happening?

<br />
int	Channel; <br />
for( Channel = 0; Channel < NumberOfChannels; Channel++ )<br />
{<br />
	Dat = (unsigned char*)m_Dither.Dat[Channel];<br />
	Out = (unsigned char*)lpDithered->Data[Channel]; <br />
	ChannelData = &(lpDthrCtrl->Data[Channel]);<br />
<br />
	//Set Memory to known state so OR'ing of dithered bits works as expected<br />
	memset(Out,0x00,OutLen);<br />
<br />

there is a lot more going on under this portion, but this is the only place that Channel is used.

you say it then equals -1.

where have you tested this value.
have you tried to set breakpoints and use your debugger to find out exactly where the change occurs ?

Im using VS2005, and i test the value using break points and checking the locals portion of the debugger. i do a conditional break at the beginning of the block if (Channel = -1). I also break at the the two function calls within this block. None of these functions take Channel as an argument. I also break at the end of the block to check Channel. Now it is impossible to check the value at each break all the time, because this function is called roughly a million times(deals with individual pixels split into various ink channels for images ~150+ Mb).
