I want to highlight selected text in a wpf textbox while the textbox is not focused. In my application, my textbox never gets focus, and every key input is done manually. I was wondering if there is a way to highlight the selected text when the textbox is not focused?

Using mfc I have an application where I'm not allowed to use a mouse and alt+tab will be regularly used. Using alt+tab to come back to my application kills the focus in the view. Once my application comes back to the foreground how can I set the view as the focus?
View 3 Replies View RelatedFor the past couple days I've been making small improvements on a program I made to keep track of a battle count while playing a game. Mainly to reduce the chore of keeping track yourself while you're playing. But it still becomes a hassle to switch back and forth between the program and your game and I was hoping to be able to set focus to the game after the BattleCount method is called.
Currently I am importing a DLL that somebody recommended I use to make a ActiveProcess method that accepts a integer as a parameter which would set the PID but it doesn't seem to be working. The two methods are as follows.
private void countDownClick(object sender, RoutedEventArgs e) {
//Calls a method within my class that subtracts and adds battle values.
counter.CalculateBattles();
//These two change text on my WPF forms with accessor values from my class.
battlesWonText.Text = counter.BattlesWon.ToString();
battlesLeftText.Text = counter.BattlesLeft.ToString();

This is the C++ code they told me to use to set focus to another application using a PID.

const UInt32 SWP_NOSIZE = 0x0001;
const UInt32 SWP_NOMOVE = 0x0002;
const UInt32 SWP_SHOWWINDOW = 0x0040;

View 1 Replies View RelatedI am trying to print a barcode form HClabel printer through my application running on Windows server 2008. The printer is a ntwork printer connected to a Windows 7 Machine.
The code to access the printer and proceed with printing is in VC++. The code has been working fine since years and it still works when I try to print from Windows XP machine(Connect and print on the same printer connected to WIndows 7 machine mentioned above).
The error code I receive when tried to print from windows server 2008 is 2 which says File not found. But when i access the machine from windows server 2008, it is accessible.
Below is the code I use:
if( m_hPrinter != NULL )
EndWriter();
m_hPrinter = ::CreateFile(lpPrinterName,GENERIC_WRITE, FILE_SHARE_WRITE, NULL, OPEN_EXISTING, 0, NULL );
if( m_hPrinter == INVALID_HANDLE_VALUE )

I have a strange problem in using C code. I want to move focus from one item to another in a keypress event (like keydown)in loop. But it move directly to the last item
Details: In the code segment, I am generating keypress event explicitly from code and want to move focus for number of items inside loop. Loop is working properly, but output is also generated after completion of loop and focus is directly coming on last item in list not showing intermediate movements. Voice output using espeak is generated correctly in each iteration.
Tryouts: I have tried to call a dilog box which take yes/no event by Btn press,that works fine. That means event generation in code is giving problem, it needs h/w intervention for keypress (As I understood)..

I'm a beginner at programming and I'm not sure how to read in information from a text file. What I want to do is take a text file which contains around 20 rows and 3 columns of numbers, and put these into an array which can then be used for performing calculations. How do I do this? Would I need to declare the size of the array beforehand? When accessing my file, do I include the full address?
The relevant part is lines 29-33:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <math.h>
/* this is a simpllified code using BEM equations */

How can I read text from a webpage asynchronously,from within C++. After you first connect to the internet using usual means, you enter the string
e.g. "[URL] ...." and the C++ program reads the information: "<title>BBC Website</title><body>This is the BBC website...." from the internet.

I have been given an assignment that has to do with permutations. I am suppose to read a text file that contains the permutation rules and the text to be "permutated", and then output the rules and the new text into an output file.
So far, I've gotten this:
Code:
# include <stdio.h>
void printArray(FILE* file, char* array, int maxSize)
{
int i;
for (i = 0; i<maxSize; i++)
fprintf(file, "%c", *(array + i));
[Code] ....
Here is what the input file looks like:
Code:
0 1 2 3 4 5 6 7 8 9
4 5 6 0 9 7 8 1 2 3
Moderation in temper, is always a virtue; but moderation in principle, is a species of vice.
Here is what the output file is suppose to look like:
Code:
0 1 2 3 4 5 6 7 8 9
4 5 6 0 9 7 8 1 2 3
ratMnioodetem rpein al,ywa isvirsetu a t m;eod
buon r inaticipp,lerina s cpeis of icvies - Temho.

The first two lines are the permutation rules. Currently I have figured out how to read the file into an array and then print it back out into a text.
What I want to do is figure out how to read only the first two line of the input file and store that as a permutation rules, and then continue reading the rest of the input file and store that separately as the text to be "permutated". And then eventually figure out how to apply the permutation to the text.

How to create text file in C programming. And after some changing in that text file off the running code of C, I want to read that modified text file back in C running code. e.g
Created file may have number 1, after changing this value to 2 let say, than I want to read that 2 value which is in text file.
In a program, I have a text file (called MyDictionary.txt) which has thousands of words in alphabetical order. I need to make a C program that reads in this text file and then makes an array called char Words[# of total words in the text file][length of longest word].
