C# :: How To Apply XAML File In Windows Form
Dec 7, 2014
I need to apply theme file in windows form but I can't. When I use the code below I get error because there is no System.Windows.Application
StreamResourceInfo sri = System.Windows.Application.GetResourceStream(
new Uri("App.xaml", UriKind.Relative));
var resources = (System.Windows.ResourceDictionary)Load(sri.Stream); ;
var app = new System.Windows.Application();
app.Resources.MergedDictionaries.Add(resources);

I want to load a file to rich text box component. I have this line:
richTextBox1->LoadFile("StudentaiRez.txt", RichTextBoxStreamType->PlainText);
But I get an error when I try to pass second parameter. It says : type name is not allowed.
I probably write it wrong, but I can't remember the correct way. In examples I only see that instead of -> dot is used, but it doesn't work either.

I need to be able to actually read my encrypted file..
I have the decryption code and works perfectly when running it through console app c++.
But, the way I decrypt is to decrypt from a file, and create a new file which is decrypted.
I can't use that kind of code in my program in windows form app c++..
I need to read the encrypted text file and decrypt it in memory while using it for my program..
Some links to my codes I use at the moment.
My decryption coded in console application: [URL] ....
My decryption code edited for form application (Did not do anything) [URL] ....
And this is the code I tried to read after it got decrypted (Reading file written in combobox_selectedindexchange: [URL] ....

I'm fairly new to visual C++ programming in a windows form and the code displayed below works fine. However my issue is as soon as the program is running it will display "failure" on label7 as soon as the button is clicked. I understand why it is doing this as "a" is not in the textbox at this time so it reads the else line and displays the message. When I enter "a" in the textbox everything works fine and label7 changes to the right message.
private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) {
label1->Text = "Question 1: test";
label2->Text = "A. test";
label3->Text = "B. test";
label4->Text = "C. test";
[code].....

I created a simple calculator in Win App. When I played it, the form is displayed blank. Not a single control is shown.
The only thing I've done differently is adding a Coded UI Test in my test project. This is the first time I'm going to try to add a coded UI test so I wonder if that's the cause for this.

I need to write a windows form application that allows the user to enter a credit card number and credit card type and then determines whether it is a valid number using the following rules:
1.) the first number is:
a. 4 for visa
b. 5 for master card
c. 37 for american express
d. 6 for discover
2.) passes the mod 10/ luhn check, which is calculated as:
a. from right to left, multiply every other digit by 2. when doubling a digit results in a two digit number, add the numbers to get
a single digit. ( like 6 * 2 = 12 therefore 1 + 2 = 3).
b. add all the single digits from 2a
c. add all the odd places from right to left in the card number
d. sum the results fro steps 2b and 2c
e. if the resulting number in 2c is divisible by 10, the card number is valid otherwise it is invalid.
The chapter is introducing methods so that is the main thing i will be using for each step.

Alright, so I'm making a windows form with a few hundred buttons, and one button will change color based on data the program receives over a socket. This is what I have, and it kind of works, but I don't want to have to make another if statement for all 260 buttons.
void hitmiss(std::string u){
std::string^ ind = reccdata2();
if (u == "button6"){
if (ind == "1"){
this->button6->BackColor = System::Drawing::Color::Red;
this->textBox2->Text = L"hit";
[Code] .....
What I want to do is make it more like
void hitmiss(System::String^ u){
std::string^ ind = reccdata2();
if (ind == "1"){
this->u->BackColor = System::Drawing::Color::Red;
this->textBox2->Text = L"hit";
[Code] ....
But it returns the error that u is not a part of Form1.

I'm building a Windows Form Application using MVP Design Pattern; the application is quite simple, it just calculates the sum of two number; So I have a form in which are located tree textbox: number1 number2 and result, plus a button to perform the action.
interface ICalcView {
string firstN { get; set; }
string firstN {get; set;}
string result { get; set; }
[Code] ....
Do you think that is a good base to start? Any code example to understand the execution flow and how to handle events?

In my class I'm trying to display the elapsed time as my label on a windows form. I've been reading up on all the different articles online and have tried these three methods all with the same result:
1. Using the System.Timers class
2. Built in Timer sub-class
3. Defining directly inside of my class the StartTime, etc. variables.
All of these still result in the following error:
Cross-thread operation not valid: Control 'User_Interface' accessed from a thread other than the thread it was created on.
Currently, my windows form is being called by another class, but I'm not sure if this is the cause of the problem.
This is a sample of the code that I'm currently using to show the elapsed time:
private void OnTimedEvent (object source, ElapsedEventArgs c)
{
TimeSpan time;
currentTime = DateTime.Now;
[Code].....

I am wanting to separate the logic from the visual, but I'm having problems when calling the method that controls the actions of the progress bar timer.
Code:
ifndef PROGRESS_BAR
define PROGRESS_BAR
class Progress_bar{
public:
void set_Progress(ToolStripStatusLabel^ label,Timer^ time){
[Code] ....
The way that I'm calling this method on Form1.h
void set_Progress(toolStripStatusLabel1 ,timer1);
Errors:

I have created a windows form project in visual studio so that I can use a windows form to interact with the game class that I'm creating, but I'm running into some problems.
For one thing, I would like to be able to call Image::FromFile() one time only during initialization, and store the result in a member variable (called mBGImage). From what I can tell, the variable needs to be of type String^ (this caret symbol is new to me, but I understand it is the "managed code" version of the standard pointer, which would look like String*).
When I try to compile the following code (located in my header file) I get the error :
"error C3265: cannot declare a managed 'mBGImage' in an unmanaged 'BSG::BSGame'".
How can I store the result of Image::FromFile() permanently in my class?
When I try to declare a global variable of type "Image^", I get "error C3145: global or static variable may not have managed type System:rawing::Image ^"
#include "stdafx.h"
using namespace System;
using namespace System::ComponentModel;
using namespace System::Collections;
using namespace System::Windows::Forms;

I want to write my own application which would fetch some data from a web site. I need to parse the HTML code of the web site and get the data.
About the application:A form (main form) that will contain data arranged in rows. Some of the data comes from a web site and some of it comes from a database.The data that comes from the web site needs to be updated every few seconds so I need to keep fetching the data from the web site.The main form will contain a button "add" which when clicked will add a new row. New data can be added to this row by the user.
I am not sure what to use for this. I have been writing the application as a Windows Form Application (Visual C#) but I do not know whether this is the best choice. Should it be a windows form application or web application? Should I use something else?

I am busy with a project, it is going to consist out of 3 different windows which is logic enough for this whole code to be interactive.
It must be able to pull data into a windows form, displaying it into a textbox, and when you click on the textbox it needs to open up another window where you will have a windows form that will display data as the code loops through the questions in the database.
I am not sure how to push the data that has been selected on the database to the next window..
Here is my code for the first window:
;
namespace WindowsFormsApplication1
{
public partial class Form1 : Form {
//SqlConnection myConnection = new SqlConnection("Data Source=(local);Initial Catalog=KnowledgeEssentials;Integrated Security=SSPI");
//int intType = 0;
public Form1()
[code].....
With the second window the data in the table needs to be displayed and each row from the table needs to have a checkbox next to them, so that if the check box is checked, the relevant information of the checked row will show up in the 3rd window... so MY question is, HOW do I pull that data from that specific database and let it show in the listcheckbox?
