Hi all. I've been using C#.net for about 6 months and love it. I have several projects that I would like to roll under one project. Now, while I understand how to import the projects in to my main project, I am having a hard time calling those project forms from my main form menu and I also get an error that my main form and the other project forms have multiple entry points.
Can someone please help me understand this quandry and help me find a solution? I'm sure you genius' out there know how to fix this and are grinning as you read this.
Sincerely,
J. Barber

You have a solution file (.sln) that contains multiple projects files (.csproj).
For one project to call some object in another project, you need to right-click on the project's references in Visual Studio and Add Reference to the other project. Then you'll be able to call any object in the project you just added a reference to.
As for multiple entry points, that's the compiler telling you that several of your projects contain a "static void Main" method, which is always the entry point for an executable. You can only have one static void main per project.

Hi Barbar,
if you create a common windows application, Microsoft Visual Studio create a project with one Form. And this form has a static Method Main. This Main is the entry point for your Application (the first called Method). All you have to do is to make sure that you have exactly one static Main method.
For instance, create a new class and add a static Main method and delete all others Mains.
It's unimportant where you define your Main method.

You can write somthing like
SqlDataAdapter adabter=new SqlDataAdapter("Select id_car,car,id_city from table1","Your connection string");
DataTable dt=new DataTable("tableName");
adabter.Fill(dt);
textBox1.DataBindings.Add("Text",dt,"id_car");
other control like datagrid have Datasource property
which you can use it to display data in the datagrid
for more info look at
ADO.NET Overview[^]
Note:
if you use database other than sql server use its data provider classes

I have the following code below to send an email. It works 100%. So I have no problem with that at all. However, if I comment out the message.Body section, and uncomment the other message.Body section, this code will no longer send out an email, and I have no idea why. Can anyone explain this?
string body = "18";
SmtpMail.SmtpServer = "192.168.0.2";
MailMessage message = new MailMessage();
message.To = "ray@email.co.za";
message.From = "test@email.co.za";
message.BodyFormat = MailFormat.Text;
message.Subject = subject;//"New Accident Management report on Risk Management Website";
message.Body = "http://localhost/riskmanagement/customer.aspx?refNumber=" + body;
//message.Body = "http://" + HttpContext.Current.Request.Url.Host + "/RiskManagement.Presentation.WebSite/AccidentManagement/AccidentMaintenance.aspx?refNumber=" + body;
SmtpMail.Send(message);

Stick a breakpoint in, and check that HttpContext.Current.Request.Url.Host returns something sensible - that might be what's confusing it

hi there,
those are just hexa number

You can interpret it as an array of length 256 that contains unsigned characters, otherwise known as 8-bit Byte values. If the 0x is the confusing part, that's just the notation for hexadecimal format. If you don't know what Hex is, then my friend, you have a lot left to learn

ok man, thanks. The 0x was the confusing part, I think that was memory address.

Hi
I am developing a ASP.Net application. My application have 5 layers. (1) Web Layer (2) Business Logic Layer (3) Data Access Layer (4) Business Entity (5) System Framework.
I want to put Exception Management Application Block (EMAB) in SystemFramework layer, so that it can be accessible from all layer. In SystemFramework layer i put EMAB (2 dlls Microsoft.ApplicationBlocks.ExceptionManagement and Microsoft.ApplicationBlocks.ExceptionManagement.Interfaces.dll), ExceptionPublisher.cs and ExceptionXMLPublisher.cs. I can access ExceptionPublisher.cs and ExceptionXMLPublisher.cs from other layers but to publish error i have to access ExceptionManager.Publish which is not accessible.
Anyone know what to do.

Hi im using a data view to populate my datagrid but am unable to use DataGridTableStyle. When populating my datagrid directly with a DataTable I set the DataGridTableStyle.MappingName to my DataTable name and am able to change the look of the table and columns without any trouble. When using the dataview i get no errors just a blank datagrid. Is it not possible to use the two together?
Here is the code anyway, if someone could spot my mistakes it would be great!
**Working Code**
DataSet ds = new DataSet();
ds.ReadXml("xml.xml");
DataGrid dg = new DataGrid();
dg.DataSource = ds;
dg.DataMember = "Players";
DataGridTableStyle dgts = new DataGridTableStyle();
dgts.MappingName = "Players";
dgts.RowHeadersVisible = false;
dgts.PreferredRowHeight = 24;
dg.TableStyles.Add(dgts);
**Broken Code**
DataSet ds = new DataSet();
ds.ReadXml("xml.xml");
DataView dv = new DataView(ds.Tables["Player"]);
DataGrid dg = new DataGrid();
dg.DataSource = dv;
//dg.DataMember = "Players"; **this line causes error**
DataGridTableStyle dgts = new DataGridTableStyle();
dgts.MappingName = "Players";
dgts.RowHeadersVisible = false;
dgts.PreferredRowHeight = 24;
dg.TableStyles.Add(dgts);
the broken code causes no errors just displays an empty grid (if i comment out the DataGridTableStyle code the grid dispalys just fine)
Thanks in advance!!

OK I want to know the best way to go about doing this as there as so many ways and they tend to get messy.
All I want is a way to add entries to a table, with Field1, Field2 etc.. (like a database table), be able to arrange by name, filter by first letter of Field1, and most importantly to be able to edit the values in the actual table and save the results.
I am guessing a DataGrid linked to a MSACCESS db, but is there another better way? I don't like the lack of usability of the DataGrid for layout and functionality. Also I need fields with an URL link that when you click it can open it

OK we have an old quaderno at work (palmtop) that has DOS 5/6 not sure which, and we use it to basically edit, and transfer text files to a PC and the CNC machines via serial using intersrv to get files to and from the PC, and a program called PSISTEM to get the files off the CNC machines, which I think just uses intersrv as an underlay.
My question is, I can create a program for the PC as normal but how would a create a network to transfer the files to the palmtop vai COM1 using the serial cable, bearing in mind the palm only has dos 5/6.
Also can I create a program to easily select and edit files in dos instead of using dos commands to browse to the files and then using the dos EDIT? Maybe learing some simple qbas or something?

How get data (form Image) to display image into our application from a device named Webcam which is capturing a person sitting on the computer. Which class does support this ?
|
|
|
|

Hello
The best way to do it is to use DirectShow. You can try to interop it or to use managed extension of DirectShow 9.
There are couple of article on CP about DirectShow usage in C# applications, for example here is one [^].
You can look at my "Motion Detection" article for a sample of communication with local capture device such as USB webcam.
With best regards,
Andrew
