I have a datagrid, which has a column called Status. In the database, the field is a text field that can have the values up, down, or danger.
I needed to display the status as a "light" as per client request, so I have a StatusToImageConverter class that receives the status, and returns the proper image to display in the datagrid column. Works fine.
Now the issue I am having... I have a combo box above the datagrid for the user to filter the results if desired. The filtering works fine, but the newly displayed devices do not have their status light. In the Status column, nothing appears after the user filters. I think it may have to do with the fact that I am not re-initializing the datagrid, but just refreshing it? That's just my educated guess.
XAML:
In the UserControl Resources:
<local:StatusToImageConverter x:Key="ImageConverter" />
In the DataGrid Control:
<DataGridTemplateColumn Header="Status" IsReadOnly="True">
<DataGridTemplateColumn.CellTemplate>
I Cant get my checkers game board to refresh every time i make a move. i have system("cls") But it does nothing of the sort.. To move a pice ive created an illusion which swaps one pieces appearance with another :
I would like to know how to make Lynx follow meta refresh links automatically, At the moment it just provides a "clickable" link you can accept the refresh. I would like this to be automatic.
--- Initial problem ---
We have a DB Backup script written in PHP/HTML and uses the page refresh to loop the backup (every 2 minutes). Using a full fledged browser is not really an option on our machine as the resources are very tight. So we tried Lynx and it has the perfect footprint but the only problem is it doesn't refresh the page.
I'm thinking I just need some way to force Lynx to reload the page after the time has elapsed. Maybe create a new function that starts a timer and hold the url until the timer ends then force Lynx to visit that url. Im a PHP Procedural kinda guy and I cant think how to set this timer event safely without corrupting or crashing the program or creating memory leaks.
(source code im using: [URL])
This is the function that handles meta refresh.
Code: /* * Given a refresh-URL content string, parses the delay time and the URL * string. Ignore the remainder of the content. */ void LYParseRefreshURL(char *content, char **p_seconds, char **p_address)
I've been using a timer to refresh the listview on my application, but after half a second, I get the error message at first try/catch method in RefreshPlot() in PlotComponent.cs:
Quote An exception of type 'MySql.Data.MySqlClient.MySqlException' occurred in Marketplace.exe but was not handled in user code
Additional information: There is already an open DataReader associated with this Connection which must be closed first.
I have a Windows service that may change the timeout of the logon screensaver in Windows (as described here.) To do that I change the following registry key to the timeout in seconds:
//user list view da = new SqlDataAdapter("SELECT * FROM [user]", con); DataTable t = new DataTable(); ds = new DataSet(); da.Fill(ds); t = ds.Tables[0]; listView1.View = View.Details;
[Code] ....
I tried with datagridview.refresh, update but its not working can any body sugesst me what to do for refresing the data ....do timer we have to use..? if yes then how ...?
I am trying to get a datagrid working in my program with populating a simple set of data. Which i can then expand on and bring in data from a database.
But even this little simple test datagrid does not seems to be working.
I'm trying to create custom WPF control, similar to DataGrid. DataGrid was great as a base class for a different custom control I needed, because I could do something like this:
public class Person { public string Name {get; set;} public string Phone {get; set;} public string Email {get; set;} }
... and I can reuse it elsewhere with collections of different type, binding its properties to columns of different width and style.
What I need now is something similar, but differs in a way, that DataGrid is no longer good fit for the base class.
What I'm interested in is: how does DataGrid "tell" the columns in Columns collection, to have the type of ItemsSource bound collection as a DataContext? How does the Name property of Person class become available to the column in DataGrid.Columns?
I have been struggling to implement a method for reading data from SQL server to my C# program. In the C# program I prepared a DataGrid (not a DataGridView) for the data to be shown in it using a button "Load Table". Now I just want to read a table which has 4 different columns which I also added to the DataGrid.
I have a DataAccessDB class and this is the code for establishing a connection:
const string DB_CONNECTION = @"It is known to me"; SqlConnection con; SqlCommand cmd; Controller myController;
Then, there is a code to reference controller:
public DataAccessDB(Controller refController) { con = new SqlConnection(DB_CONNECTION); cmd = new SqlCommand(); cmd.Connection = con; cmd.CommandType = CommandType.StoredProcedure; myController = refController; }
And this is the code for a List which I am going to use for filling the data to a DataGrid:
public List<ProductionStock> GetProductionStockFromDB() { int productionStockId, amount; decimal price; string name, descript;
[code]....
And now the main part - how to read the data when I press a LoadTable button. The point here is that I already defined connection strings here as you can see, and in the method itself I guess I should not repeat it. The tutorials I have seen they do it everything in that one button.
the code works and produce a table and fills the grid, what im trying to do is get this information into a DataGrid, so i can get rows selected by user. ive tried many ways ie convert the list into a datatable and display but produces errors, ive done the following,
ive added the HTML code to set up the datagrid, which i can see via design tab, but filling it up is harder.
i uderstand it needs a
protected System.Data.SqlClient.SqlDataAdapter sqlDataAdapter1; sqlDataAdapter1.Fill();// where it require a dataset or datatable DataGridProduct.DataBind();
as it requires a datatable i converted the list to a datatable when i run it it says null, im not sure where im going wrong, i noe the list works as i tried populating on a table.
public static DataTable ToDataTable<T>(List<T> items) { }
I want to be able to keep on adding a row to my datagrid every time i click a button, the row will hold the text of the text box and the combobox in its individual cells, is there a way to do this without inserting a ridiculous amount of code?
I have made a datagrid in a WPF and added a button to add rows, here is the code for that:
this.itemListDataGrid.Items.Add(new TextBox());
Also, I have already got 3 colums in the datagrid pre-added by me, so when the rows are added I click on one to edit it and it comes up with error edit item not allowed.
but when i select a collumn, i recive an error because i'm selecting a cell with the mouse and i dont have code for that selection. My question is how can i put an "if" on the beguining of the event so that he can determine if it's a header or not.
In my WPF application I created a LINQ to SQL entities class. Then I created a partial class and there add code to my entity class. Below is the code of it:
Then I executed LINQ to SQL. Works perfectly well. Then I bound WPF Datagrid radiobutton column to is_selected property of the partial class. Below is XAML code:
And here I have the problem. When I'm changing the radiobutton status from Unchecked to Checked it doesn't change the value of is_selected property from false to true in the partial class. I don't know why.
I am currently just trying to update a record in a SQL database.I can add a record and delete a record just fine but when I go to update I get no errors but it just doesn't update.
Here is what I have and done coding for hours trial and error
private void btnAddProd_Click(object sender, RoutedEventArgs e) {//validate method // product = new Product(txtProductName.Text, Convert.ToDecimal(txtProductCost.Text), txtProductType.Text); product = new Product(); MakeProduct(product); if(modify) { Product theOneAndOnly = new Product();
I want to search for the "movie_code" and change the [movie_status] from Active to Inactive.
So lets say for example i have a movie code 12345 saved in my movie file. I want to change the value from "Active" to "Inactive"for argument sake.
This is the code i was trying to do it with:
FILE *movie_fp; movie_fp = fopen("movie.dat", "r+b"); int m_code; MOVIE movie_data; printf("*** Welcome to the movie updater! *** "); if(movie_fp != NULL){
I've just integrated the Windows SDK V7.0A into my VS2005 application, and I'm getting the dreaded "Application configuration error" when I try to run it on an XP machine.
It runs fine on the development machine, and some customer machines (Win7 and Win8), but will not run on XP due to missing/incorrect version dlls.
I've rebuilt all my libraries, but still no joy.
So, my first question is - If I upgrade the Windows SDK to V7.0A, do I also need to use MFC 10 and msvcrt10, or can I stick with MFC 8?
The next question is, how do I find out which dlls are missing, and which libraries or other dlls are requesting the missing versions?
I am writing a program that manages a group of tool bins. This group is handled as an object that is an array of two element structures called InvBin. I initialize the bins with data from a file which contains the descriptions and initial quantities. I also have functions to add or subtract items from a bin and a function to display a report of the description and quantity of all of the bins.
The add and remove functions work correctly based on the cout statement in the functions, however when I display the report, it displays the initial quantity instead of the new quantity. In addition, when I use the add and remove functions again on the same bin, they use the initial quantity.
These are the add and remove functions and the report function from the main program.
Code: //Adds an item to a bin void addItem(HANDLE screen, BinManager tools, int &count) { int binNum; int addNum; system("cls");
I am having trouble updating my global pointer in the following code,
Code: #include <iostream> using namespace std;
struct RB{ RB()=default; RB(int clr):color(clr) { } int color;
[Code] ....
The problem is, at line where I compar y==Tnil, It is evaluating to false at the first insert. But It should be true. again, after ending the function, T again becomes equal Tnil, as a result , none of the is being inserted.
