C# :: Assigning Dbcontext Object To Label
Jul 29, 2014
I have a dbcontext object from a table that I'm trying to assign to a label, but the page is blank and the label doesn't show the output. How can I successfully assign a label on button click so that the table data is visible? The object I'm referring to is aMessage.highScoreEasy
protected void myScoresButton_Click(object sender, EventArgs e) {
int num = 2;
int num1 = 5;
int num2 = 6;
easyScoreLabel.Text = num.ToString();
mediumScoreLabel.Text = num1.ToString();

I have the following code.
StackElement *StackElementArray;
StackElementArray = new StackElement[iMaximumDepth];
I want to assign one element of this array StackElementArray the address of another object. For example,
voidStackMem::push(StackElement &iStackElement) {
CurrentDepth++;
StackElementArray[0] = iStackElement;
}
The StackElement class contains pointers to some dynamic arrays. When I use the assignment, StackElementArray[0] = iStackElement;, it doesn't copy the complete contents and I have to define an 'assignment operator' function to copy all the contents. I am wondering if there is a way I can assign StackElementArray[0] the pointer to the StackElement object. In that case, I will not need to copy the contents of iStackElement into StackElementArray[0] and will just copy the address.

I am stuck on my program right now, what i am trying to do is get the sum of the amount from a access database table and than display it on a label, however i cant seem to get this to happen. This is what I have so far:
OleDbConnection conn = new OleDbConnection();
conn.ConnectionString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=Church.accdb";
conn.Open();
Form1 frm1 = new Form1();
//frm1.Show();
//string tableName = frm1.tableName;
//string time = "4/5/1991";
string fullName = memberscmb.Text;

I'm trying to print numbers in a label but I'm not having success. For example, I have the following code:
private: System::Void txtLeftWheel_Click_1(System::Object^ sender, System::EventArgs^ e)
{
for (int i = 1; i <= 1000; i++)
{
Sleep(100);
this->lblLeftWheel->Text = (Int32::Parse(this->lblLeftWheel->Text) + i).ToString();
}
}
The idea is that when I click the button, the numbers on the label increment from 1 to 1000.
The Sleep() is there to slow down the loop and the user can see something happening. However, if I put the Sleep() before the label->, the form freezes completely. If I put the Sleep() after the label-> text, the form freezes for a few seconds and the label text goes from 1 and jumps straight to 1000.
The expected functionality is that the label displays numbers 1 through 1000 but increment every second.

I have a label on my main form. When I menu select my settings form, I make a change to the label text on the main form but the label text does not update with the new text.
So here is my code in my settings form:
MainForm frm = new MainForm();
frm.paintMainFormThemeTitle(logoText); // updates the main form label
I may not fully understand the new instantiate key word, but doesn't this create another, new copy of my main form to operate on? And isn't that why I can't see my label text change on my main form that is previously in view?
All of the examples that I have been able to find show using this new key word to be able to access a component on another form. But to my understanding, I'm creating another, new form.

In my program I have WinForm and on this WinForm I have a User Control. On the User Control I have a TreeView.
So what I'm trying to do is passing a number, which is in the TreeNode Text to the WinForm. On the Winform I have a couple of Labels which I want to fill with Informations. To get those informations I have a class with a method which Needs my number from the User Controller. But I can not Access the Labels in the WinForm Method.
Here my code:
User Control
private void TreeView_SelectedNode(object sender, TreeViewEventArgs e) {
CwiaMain frmMain = new CwiaMain(TFS, TfsConnect);
TreeNode tn = _tvWorkItemList.SelectedNode;
if (tn == null) {
MessageBox.Show("Error");

With the LoadLibrary function (followed by GetProcAddress) you can get a function or any other thing that is on DLL export. AFAIK, when you assemble one program, it loses all user-reading data (names in general). How do the OS's get them?

System.Drawing.FontStyle newFontStyle;
newFontStyle = FontStyle.Regular;
expanderLabel.SelectionFont = new Font(
currentFont.FontFamily,

My program has a goto label in it and when the program is not instructed to goto the label, it does. When control goes to the line that it is on, even if no where does it say to execute the label's content, it does execute it.

This program was running at first but when I started to change the couts and cins to fouts and fins (in order for them to be save in a file directory), it shows a lot of errors such as:
initialization of 'fin' is skipped by 'case' label
'std::ifstream fin': redefinition
Here is the code of the program:
#include <iostream>
#include <iomanip>
#include <fstream>
using namespace std;
struct file{
int fnum;
char fname[50], lname[50];

I thought we needed to allocate memory before assigning a value to a char* and also that we needed to use functions like strcpy() to copy something into it. Then how come this works and does not crash?
Code:
#include <iostream>
using namespace std;
int main()
{
char * buf;
buf = "Hello";
cout << buf << endl;
buf = "World!!!!!!!!";
cout << buf << endl;
return 0;
}

I am trying to understand the behavior of following code. Basically how does printf() prints the value rather than address.
Does initializing value to a pointer during declaration makes a difference when assigned from a variable?
Code:
1 #include <stdio.h>
2
3 int main() {
4 const char *var1 = 'A';
5 int *vint = 10;
