A self-explanatory message, you are trying to access a file or folder which does not exist.

It could also be showing that he's lost in a forest, and that he's forgotten to leave a trail of gingerbread crumbs to find his way out with.

I think that's error code 0x0BADF00D.

You are saying that the "message show path not found".
- That is the issue. Have you hard-coded any paths in your application? Go through your entire application and look for all the used/referenced paths. Make sure the paths are relational.
- Use proper logging to record the exceptions thrown.

Hello,
I have problem to put variables to reportviewer.
First I put variables to parametrs and then to reportviewer.
Code looks like that:
jodb baza_win = new jodb(.....data.....to.....connection......SQL);
List<DaneRaportu> lista = baza_win.pobierz_rap_view(......query......SQL)
reportViewer1.ProcessingMode = ProcessingMode.Local;
LocalReport localReport = reportViewer1.LocalReport;
reportViewer1.LocalReport.DataSources.Clear();
reportViewer1.LocalReport.ReportEmbeddedResource = "Raporting.Report_Promo.rdlc";
Microsoft.Reporting.WinForms.ReportDataSource dataset = new Microsoft.Reporting.WinForms.ReportDataSource("DataSet1", lista);
reportViewer1.LocalReport.DataSources.Add(dataset);
dataset.Value = lista;
string data_rap = "Dataprobna";
ReportParameter nowydataod = new ReportParameter("dataodview", data_rap);
this.reportViewer1.LocalReport.SetParameters(nowydataod);
Next in report I put parameter to textbox. Expression looks like that: Parameters!dataodview.Value
When I start program I get this communication:
An error occurred during local report processing
In details:
Microsoft.Reporting.WinForms.LocalProcessingException: An error occurred during local report processing. ---> Microsoft.Reporting.DefinitionInvalidException: The definition of the report '' is invalid. ---> Microsoft.ReportingServices.ReportProcessing.ReportProcessingException: An unexpected error occurred in Report Processing. ---> System.UnauthorizedAccessException: Access to the path 'C:\Users\User\AppData\Local\Temp\expression_host_1f2d7bdeb7b24b8a9d99ff74d15a1b60.dll' is denied.
at System.IO.__Error.WinIOError(Int32 errorCode, String maybeFullPath)
The strange thing is that when I start program in Start Debugging everything is ok but when I start program in Start Without Debugging I have bug.
Maybe someone knows what happened?

Same way as a button column; you handle the CellClick[^] event of the DataGridView. It works the same for button and text-columns.

No, it ain't. We're volunteers, it cannot be urgent here.

Sorry Eddy its mistake. No Urgent I understand

Hi Eddy, but can you please provide me the code for saving the cell click means that it is clicked into the database because there is a need .

Check the link, it contains an example (without the database code).

Perhaps you can help me in my search as I know very little C#. I'm looking at delegating functions and marshalling the function pointer to a win32 p/invoke function. I think my issue is with delegating. Basically I've set up a delegate function (to simplify I'll use):
public delegate void Foo(int x);
Then I declared a delegate member
Foo f;
Then I assign it to an appropriate function:
f = this.MyFoo;
Which was declared like:
public void MyFoo(int x){...}
I then get the function pointer via Marshalling:
win32function(handle, Marshal.GetFunctionPointerForDelegate(f));
Currently I'm getting an error for the win32function() of invalid parameters. The only parameter I cannot be sure is correct is the function pointer I'm passing [the win32 function is looking for a callback function]
I'm assuming I'm not completing getting the picture of delegating. Any ideas?
I can dump the working code into the forum but I was trying to keep things simple.
Thanx
Dennis

I think you need to use the UnmanagedFunctionPointerAttribute on your delegate; see if this is useful: [^].

My question is how can we save button click event state in database that whether it is clicked or not means if user click the button then automatically it will save as yes in database. I am using SQL Serve 2008 r2
Please help me out
Thanks

How do you intend to notify the database that the user has NOT clicked the button.
Trapping the click event is trivial and will depend on the UI you are using, you did not mention that!

Mr. Mycroft I don't know whether you know or not but
"Human Stupidity Is the FATHER of INNOVATION"
I clearly mention that this application is in windows Form and you going on talking about UI if you are not able to give the answer then please don't make it complex.
I know you are a intellectual programmer but please. And thanks for your reply

Before you get insulting, you should really check what you posted. In your post you state
"My question is how can we save button click event state in database that whether it is clicked or not means if user click the button then automatically it will saved as yes in database else
no. I am using SQL Serve 2008 r2
Please help me out

Where, in that, does it say anything about Windows Forms?

Where!
If you are using windows forms then trap the click event (double click on the button in the designer to create the stub).
Check the value of the control and write the result to the database.
However your design is stinks, what happens if the user never clicks the button, what happens if the user clicks the button 15 times.
And yes I am trying to make it complex, you need to think through what the user can do. It seems a checkbox would be a better control for this requirement.

can some body tell me about the logic for creating my own forum using c# in asp.net?
|
|

Where are you stuck? Clearly you'll need a database to store your data but then the layout and how it works is up to you.
There are only 10 types of people in the world, those who understand binary and those who don't.

I'd recommend downloading an open-source forum-application for ASP.NET, and taking a look at the source-code.
That text is the programming logic. If you want to create your own you should study C#. If you want to be up and running quickly and mucking with databases fast, I'd recommend the tutorials from w3schools.
