You made a HUGE mistake by relying on Flash. Flash is dying, fast. YouTube's default video player has been HTML5 video for about the last year.
On top of that, what you're doing violates the YouTube terms of service. Using any other play other than that supplied by YouTube is expressly forbidden unless excepted by written authorization by YouTube. Good luck getting that.
Yeah, Flash is updated by Windows Update on Windows 8 and above. It's no longer handled by Adobe and, frankly, Adobe is shutting down support for Flash except for gaming and "premium video", which does not apply to YouTube.
YouTube reserves the right to change their support and how they deliver video at any time and has done so multiple times in the past to prevent you from using your own player. What works today is in no way guaranteed to work tomorrow.

Dave,
Thank you for your input and response. I am fortunate that someone with your depth of knowledge and credentials took the time to bring me up to date. Since my use is for an application and not a webpage, HTML5 is and never was a solution for me. I understand the legalities and I thank you for bringing it to my attention, but I don't think that there are less than 100 videos posted ON YouTube that explain how to use the Shock-wave Viewer in a C# form to view the content of videos posted on You Tube. Like most things today, and as You Tube already knows (or has found out), as quick as they make a change there will be some one with a new key for the lock. It is not possible to post something in the public domain without having someone else contrive a way to get around it. That said, I prefer to do it right and I will simply have to find (or create) a service and/or system that will let me continue to have videos viewed privately from within proprietary software. Perhaps I will change the videos to (mp4) and host them on my own server. Then I can use the Microsoft Media player that already has libraries in Visual Studio. In my case, the most disturbing thing was the timing. Thank You Again. I would like to be able to call on you for advice and perhaps even do some work for me if you are interested. Best Regards, Pat.

Well, just because "everyone is doing it" in no way at all makes it OK for you to do it.
You're not going to get help with this for 2 reasons.
1) Per the YouTube Terms of Service, what you're doing is a copyright violation. The content belongs to YouTube. The content is not "public domain" and you really don't get to do with it as you please.
2) You're stealing money. By creating your own video viewer you are filtering out the ads that come with the content. That ad money is what pays the bills for the service and also puts money into the pockets of the content producers. By rolling your own viewer, you are taking away that ad money.
Oh, and why would I want to work for someone who thinks so little of other peoples work that you don't want to pay them to do it?

I have a trouble with my code in trying to add a combobox to filter a datagrid. It complains in the dataview constructor ("The best overloaded method match for'System.Data.DataView.DataView(System.Data.DataTable')has some invalid arguments".
It also complains in the declaration of rowgrid object: 'System.Data.DataSet' does not contain a definition for 'DefaultView' and no extension method 'DefaultView' accepting a first argumentof type 'System.Data.DataSet' could be found (are you missing a using directive or an assembly reference?)

The DataView Constructor[^] that you're intending to use expects a DataTable as argument, not a DataSet. But you can as well assign the DataTables DefaultView to the ComboBox' DataSource:
comboBox_NIF.DataSource = ds.Tables[0].DefaultView;
(Assuming it's table 0 you want.)

What´s the best way (changes in my code) to solve this problem in order to have the combobox filtering specific columns of the datagrid?
|
|
|
|
|
You could add an EventHandler-Method to the SelectedValueChanged- or SelectedIndexChanged-Event of the ComboBox and therein set the RowFilter-Property[^] of the DataView of the DataTable that you set as the DataMember of the DataGridView.

Please post the name of the exception and the stacktrace; it will make it easier to help you with that.

The error is "reference not set to an instance of an object". This happens when I change the content of the cell respective to the column ('nome') after aplying the filter ('nome'). If I don't apply this specific filter, the content change is made without any errors.

The error is logical because the datagrid is not assuming the change of the data after I apply the filter 'nome', it considers as no data to fill the datagrid. The problem is why this happens. When i change data in any column other than the one regarding the filter, that data is considered and the datagrid is changed or filled with new data, but when I apply the filter, the datagrid becomes empty at the moment I press the button to change the data.

Ok I think I got it now. The cause will probably be that your code behind the button "gravar" tries to access that row which isn't part of the view any more because when your input cursor leaves the cell edit control (when clicking the button) the filter gets automatically re-applied so that the row gets removed before the code behind "gravar" gets executed.

I tried that solution and it solved my problem regarding the edition of filtered column, but it brought another problem which is not being able to edit any other column when the filter is not applied. The error has the same message: "Object reference not set to an instance of an object", and appears in the function private void grid_lic_CellEndEdit(object sender, DataGridViewCellEventArgs e).
private void grid_lic_CellParsing(object sender, DataGridViewCellParsingEventArgs e)
{
id = int.Parse(grid_lic.Rows[e.RowIndex].Cells[0].Value.ToString());
}
private void grid_lic_CellEndEdit(object sender, DataGridViewCellEventArgs e)
{
dt.DefaultView.RowFilter += " OR id=" + id.ToString();
}

I apparently solved this issue using a new variable bool filt to be false as default and set to true after the application of the filter. If this variable is false then the filter has not been aplied and it edits the columns as previously, if the variable is true, then the filter is set and it lets me edit the filtered columns, after which is again set to false, allowing the edition of non filtered columns. Thank you very much.

Sample table
RC ABC GORDON
RC XYZ Biz
RC PQR SERT
Expected Table
_____ | ABC GORDON
_____ | XYZ Biz
RC | PQR SERT
|
|
|
|
|
What kind of table? A System.Data.DataTable?
Why would the expected table have to be like you posted and not
RC | ABC GORDON
___ | XYZ Biz
___ | PQR SERT
..for example?
And did you try anything yourself? If yes, please post it. If not, why not?

Hi Sascha Lefèvre, thank you for replying,
Yes you are right, I have to work on System.Data.DataTable.
All cells has common data, so it should be merged.
|
|
|
|
|
A DataTable is just a collection of data. It doesn't have "cells", and it wouldn't make any sense to "merge" values within it.
I suspect you want to merge the cells in whatever control you're using to display the data from the DataTable. You need to tell us how you're displaying the data.

Your question is not clear. What "table" are you referring to?

Hi, I have an Employee class with Name, Department, and Salary as properties. All I'm trying to do is add an employee to a list of Employees after typing in all the required info and hitting the Add button on my form.
Then I want to display the employees in the list of Employees using a foreach loop. Below are my code but they're not working and I get no errors.
namespace CSharpListObjects
{
public partial class Form1: System.Web.UI.Page
{
List<Employee> employees = new List<Employee>();
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnShowEmployees_Click(object sender, EventArgs e)
{
StringBuilder employeeDetails = new StringBuilder();
foreach(Employee e in employees)
{
employeeDetails.Append("< br/>Name: " + e.Name
+ " Department: " + e.Department
+ " Salary: " + e.Salary + "< br/ >");
}
Literal1.Text = employeeDetails.ToString();
}
protected void btnAddEmployee_Click(object sender, EventArgs e)
{
Employee employee = new Employee();
employee.Name = txtName.Text;
employee.Department = txtDepartment.Text;
employee.Salary = Convert.ToInt32(txtSalary.Text);
employees.Add(employee);
}
}
}
It appears there is nothing in List < Employee > after I added Employee objects. Please help point out where my mistake is if you can spot it, thanks.

I see that this is a question about an ASP.NET project. We do have a dedicated forum for that, that you should consider posting questions like this on, in the future.
Anyway, the problem is because your list of employees is lost between one postback and the next. You have to consider the nature of a web site, which is short lived in the duration of what happens in the code because each post back from the client to the server effectively fires off a new instance of this page. What you need to do is either store your list in a cache or a session object and then retrieve it from there. The choice of whether to host it in the Cache or in a Session depends on whether you want this list to be visible to everyone (stored in the Cache), or just for the user who is entering the current details (store it in the Session).

Hi Team,
I have a C# app where the only localization that needs to be done is in the Menu Strings. So instead of the strings being stored in a resx file (OR BAML), I was thinking of storing that in a keyvalue pair .properties file that can be dynamically updated from a CDN. This way if a new locale has to be supported, all we need to do is add the corresponding property file for that locale.
Anyone tried this approach and any recommendations/things I have to take care of?
Thanks,
Chandra
