Well, you have to tell it what "Program"...

Of course, leppie could have misinterpreted your initial question. Given the context of the forum and without additional qualification in the original posting, it reads as if you are asking: I am launching a console application from within another application, but how do I ensure that the Console window does not appear?

Welcome to the "Point-and-Click" programmer age.

I think that dude just didn't enable a feature in the compiler that allows
mind reading behaviour. Add the "/Cmr" option. It's a wonderful option that allows basically any code with undefined variables to compile without a problem, by just asking a telepathic question to the dumb a** programmer cutting and pasting something out of a internet forum.

Working with IRC

Hello!

I want to learn how to work with IRC and make a IRC Client (very easy one) so I searched alittle and I only found a C# IRC Bot on c-sharpcorner:

http://www.c-sharpcorner.com//Network/IrcBotPH.asp

I downloaded the source code and got the two classes used. But how do I test this? There is no project in the sorce code only two .cs files. When I open them I can't run them. Can someone help me with what I need to do to make it run?

Create a project, add the two .cs files and then create an object of the IRCBot class?

Thanks in advance!

Either put them in a new project or use the C# command-line compiler to compiler them both. Type csc.exe /? on the command line (if %WINDIR%\Microsoft.NET\Framework\v<version> is in your PATH environment variable). Read the .NET Framework SDK for more information.

Dear sir
+. I'm using Tapi3.1 and C#.Net for developing simple Phone Application

A quick google search on "TAPI detect silence" turned up the following result from the Microsoft Developer Network (MSDN) as the first result: http://msdn.microsoft.com/library/en-us/tapi/tapi2/linemonitortones.asp[^]. Simply P/Invoke the API and pass a tone frequency of zero to monitor for silence.

This is the C# forum, not the modem/hardware forum. Just like I (easily) found the article I linked above, so should you try to search for your answer. You can also check the OEM's web sites for information about their modems, which is the first place I would've checked.

Buy proper hardware if you are writing a proper CTI/IVR application.
If it's not targeting consumer market, opt for some of Dialogic's cheap hardware, such as the D4/PCI board.

If you are writing software to work with modems, you should know the limitations and not use features that most definetly won't be supported by the driver(and TSP). Silence detection, positive answering machine detection, positive voice detection and more are all domain of more advanced hardware boards. Anyway Brooktrout and Dialogic are leaders in the field at the moment, so that's where you should be looking.

How can I Edit a Readonly DataGrid?

Hi,
I want to edit just a cell or a row in a DataGrid.
I think that I have to set Readonly property to true, but when I change this property to false all cells and rows will be editable.
I know I can have it easily in web application, but I want to know how can I do it in C# windows application.

Re: How can I Edit a Readonly DataGrid?

Edit the data itself and update the DataGrid. This works different than in ASP.NET because it is different that in ASP.NET. In Windows Forms, it's a control. In ASP.NET, it simply generates different HTML based on state. There's a big difference.

Once you've edited the data (like a DataSet, which you should use the DataTable.DefaultView to take into account any re-ordering), you can re-data-bind your control either by setting the DataSource property to null and then back to the DataSet (or whatever), or refresh the CurrencyManager like so:

CurrencyManager cm = (CurrentyManager)
  dataGrid1.BindingContext[dataGrid1.DataSource,
    dataGrid1.DataMember];
if (cm != null) cm.Refresh();

Datagrid and a checkbox

I have seen this done before but am still not clear on exactly how it is done cause for some reason its not working for me. Here are the steps I have taken.

1) Make a DataGrid 2) Make the DataAdapter 3)Make the Dataset 4) set the properties of the datagrid Source=dataSet11 Member=Movie 5) then the code

I have 2 columns in my dataset one title the other information. I want to add a checkbox so I try to do something like the following.

oleDbDataAdapter1.fill(dataSet11);

/**********************************************
 * want to make a check box so i try this
 **********************************************/

DataGridTableStyle tablestyle = new DataGridTableStyle();
tablestyle.MappingName = "Movie"; // map it to my table name
DataGridColumnStyle boolCol = new DataGridBoolColumn(); // make the bool box
boolCol.MappingName = "Current"; // name it 
boolCol.HeaderText = "Info Current"; // its header
boolCol.Width = 70; // its width
tablestyle.GridColumnStyles.Add(boolCol); // add the bool style 
dataGrid1.TableStyles.Add(tablestyle);// add the style to my datagrid

All i get is a datagrid with no fields, or rows. It should be simple to fix but I'm drawing a blank.
Thanks for the help in advance.

Don't declare your DataGridBoolColumn as it's base class: declare it as a DataGridBoolColumn and set the FalseValue and TrueValue members. Then add your DataGridBoolColumn to the DataGridTableStyle.GridColumnStyles property (no need to cast it - it's a derivative class).

In general, declare your variables as the type you instantiate so you can access members declared by the type. It's still an instance of its base classes.

Handle Click on MenuItems with sub menu

jeegar4-Jun-04 14:47

4-Jun-04 14:47

Is there anyway I can handle click event on a MenuItem which has sub menu. The default behaviour is the click opens up the submenu.
I want to handle the click in two different ways in different circumstances.
In one circumnstance I want to go for default behaviour to open submenu
in other I want to go to the click event handler on this MenuItem.

For some (good?) reason MenuItem is not derived from Control so I can't override WndProc. Does someone know how to catch mouse events on Menu ?

Also is it possible to figure out exactly which Point on the MenuItem did the user click ? I can use this to draw a OwnerDrawn Menu and achive what I want.

waiting eagerly for some suggestion

Why should a MenuItem derive from Control? A MenuItem simply encapsulates an HMENU (menu handle) and the related Windows APIs - it is not a control nor does it even act like the control. There's no good reason that it should derive from a control.

Read the Platform SDK for more details.

c#-configuration file

4-Jun-04 11:20

i am working on n tier application and got 3 projects on my soloution.
in the end i just supply dll file.
the upper layer is a test one and its not part of the dll that i have to supply. i want to use the App.config file and i dont want him to be at the test layer(because its not part of my dll), i want to create the app.config file at the middle layer(which is my Data access layer).
The problem is that when i am creating the App.config file at a project that is not set as startUpProject i cant read from him or write.
the only way i can read from the App.config is when i am creating him under the StartUpProject.
How can i use an App.config file for my entire Project(3 projects) and not to put him under the StartUpProject and after all i will be able to use it ofcoures
thanks

Only .exe's and ASP.NET web applications automatically read from a .config file. The app.config file has to be in the same directory and named the same (plus .config at the end) as the executable file. DLLs do not automatically have their own .config files unless you create your own executable loader (not an easy thing) or create a new AppDomain with a separate .config file just for a DLL.
