1. How can I display an image, like an image editor, in full screen mode?
2. What is the fastest method displaying an image (both in window or in full screen)? Some programs work much faster than others; scrolling an image takes much longer with some programs than with others.
Thanks

StretchBlt is a different issue. In the meantime I found that both SetWindowPos and MoveWindow work with the co-ordinates (0,0) as well (I had thought that would be rejected).
However, this is probably no help for my original problem: performance.

I'm trying to sort an array of race objects by its raceid and I can't figure out what's wrong I don't seem to get any weird errors other than the most obvious that it doesn't work. Could someone point out what's wrong with my code?
Thanks!
void sortRaces(race theRaces[], int number_used)
{
int index_of_next_smallest;
for (int index = 0; index < number_used - 1; index++)
{
index_of_next_smallest = index_of_smallest(theRaces, index, number_used);
swap_races(theRaces[index], theRaces[index_of_next_smallest]);
}
system("cls");
skip(2);
pause("The races have been sorted");
}//end sortRaces
void swap_races(race &race1, race &race2)
{
race temp;
temp = race1;
race1 = race2;
race2 = temp;
}
int index_of_smallest(race theRaces[], int start_index, int number_used)
{
int min = theRaces[start_index].getraceID();
int index_of_min = start_index;
for (int index = start_index + 1; index < number_used; index++)
{
min = theRaces[index].getraceID();
index_of_min = index;
}
return index_of_min;
}

The second best way to do this is a bubble sort, which basically is a nested loop that swaps elements with the one next to them as needed, in the inner loop. The outer loop means it's called often enough for the item at the bottom to get a chance to 'bubble' to the top if need be.
The best way is to store your objects in a vector and write a function object to pass to the sort function.
Here[^] is my article on how to do that.

When I refresh a Edit Control’s text every 1.5second, the Edit Control flashes occasionally. Anybody can tell me why and how to avoid it.
In same application, my other Edit Control do the same things, but won’t flash.

Hi all,
This is not a problem I'm seeing with my own applications, but this can definitely be labeled a programming question...
Right now I have two applications running on my machine that are consuming over 2000 handles each: Outlook 2003, and RSS Bandit.
SysInternal's Process Explorer shows that both of these have hundreds of handles to HKCU\Software\Microsoft\Windows\CurrentVersion\Internet Settings\ZoneMap being held.
Searching Google for "leak" and "internet settings\zonemap" comes up with a few hits, one of them from some guy claiming that a simple C app that brings up a dialog box with IE and then destroys it is leaking two handles to that same key. That post is dated February of this year, and it had no reply.
I'm running XP Pro with all the latest updates.
Anyone else? Thoughts, comments?

I'm trying to search an input file for all occurences of a user specified string and return how many times the word was found and read that into an output file. For some reason the the value of the string changes to every word in the text file at runtime. What am I doing wrong?
#include <iostream><br />
#include <string><br />
#include <ciso646><br />
#include <fstream><br />
using namespace std;<br />
<br />
int main(void)<br />
{<br />
<br />
<br />
string filename;<br />
cout << "Please enter the name of the file: " ;<br />
cin >> filename;<br />
string search;<br />
cout << "Please enter the word to search for";<br />
cin >> search;<br />
<br />
ifstream fin(filename.c_str());<br />
while (fin.fail())<br />
{<br />
cout << "invalid file name"<< endl;<br />
cout << endl << "Please enter the name of the file: ";<br />
cin >> filename;<br />
<br />
fin.clear();<br />
fin.open( filename.c_str() );<br />
<br />
}<br />
<br />
int count=0;<br />
<br />
while (fin >> (search))<br />
{<br />
<br />
count++;<br />
<br />
}<br />
<br />
ofstream fout("output.txt");<br />
fout << "The number of times "<< search <<" was found is "<< count << endl;<br />
<br />
<br />
<br />
<br />
<br />
<br />
<br />
system ("pause");<br />
return 0;<br />
}

Binary,
Your problem exists here:
while (fin >> (search))
{
count++;
}
You are reading a "word" from your file and storing it in the string that you declared to hold your search term. Instead, reuse the filename variable or declare a new one.
while (fin >> (filename))
{
count++;
}

Hi!.
I'm trying to build an existing VC++ 6.0 activex project for Pocket PC with Visual Studio 2005.
With the "Configuration manager" I have added the plataform "Pocket PC 2003 (ARMV4)", that's what I want for now.
But the compiler throw the following error:
"Error 1 fatal error C1189: #error : Must define a target architecture. c:\Archivos de programa\Microsoft Visual Studio 8\SmartDevices\SDK\PocketPC2003\include\winnt.h 648 "
So, it looks that in some place I should define the target architecture, (ie: _WIN32, but for WINCE), but where?, and what is the #define???
Thank you.
Demian.

Hi,
Where to put my Registration or Login Screen Dialog in a Document/View SDI (MFC) application ? I tried to the InitInstance but i get Assert errors.
I suppose there are two ways to show this dialog, 1)Before the application starts 2) Just after the Application start
Regards,
George

I usually do this, after the application has started. If you don't want to show the main dialog, hide it after InitInstancd and before showing the registration one ...

Hi,
In Initinstance
m_pMainWnd->LaunchLoginScreen();
In mainfrm.cpp
LaunchLoginScreen()
{
LoginDlg = new LoginDlg();
LoginDlg->DoModal();
delete LoginDlg;
LoginDlg=NULL;
}
Bye,

Hi,
Is there any way in MFC to have global variables ? I need this, for example to have access to a database connection string, from anywhere in the program not only in the Document/View but in the Dialogs too.
Regards,
sdancer

I've used 2 different approaches:
1. Define a static class called CGlobal and define it with static variables and functions.
2. Make it a member of your Application class and use theApp.m_connectionstring

I tend to put them in stdafx.cpp, and extern them in stdafx.h.

I believe in making Singleton class and use it object in while application!

my app send 1 byte (value='11111111') to LPT1. In one PC (Win2K-PRO) I see value:'11111111' but in other PC I see value:'00111111', pin D7,D6 always is '0'.
Why ? How to set LPT ?
|

To input using the data byte (pins 2-9), the port should be configured as bi-directional; i.e, can input and output on the same pins. There is a bit in I believe (forgot the address, either 0x379, or 0x37A), which needs to be set to input data from the port, instead of the usual output.
If you have already made it bi-directional, then there is something wrong with the wiring, or the port, or it is something else. 
this is this.

Outport(0x378,ch) that is ok, but Inport(0x378) always give last value, that was Outport before.
