Hello.., i'm working on a project, where i have a dataGridView, that get's it's data from at database (Access).., that works...
In the database (MusicCollection), there are several column's, ex: "Type", that contains "CD", "LP", "Single" etc.
In the Properties for ComboBox1, i have set the dataSource to "MusicCollection" and the displayMember to "Type"
That works, but if there are 100 CD's in the database, "CD" appears 100 times in the combobox...., and i only want 1 occurence for each Type...., like the sql-statement: SELECT DISTINCT Type FROM MusicCollection
I would like to use a sql-statement, but i don't know, where to put it...
I use Visual Studio 2005 Express.
(i'm sorry about my pore english )
I hope, that someone can help me.

this.DropDownList1.Items.Clear();
this.DropDownList1.datasource:=dataset.tables["MusicCollection"];

A goal is:
if u load your form or you make any event example by clicking button or any other enevt dropdownlis fills again. this is multi-dupliacted data.
every time clear combobox then fill it again from ur table?
hope i was clear???
dropdownlost.items.clear();
dropdownlost.datasource.dataset["TableName"];
dropdownlost.DataBind();

I have a paremeter in an xml file that can contain one of a dozen discrete, non contigious integers. To enforce the limited selection I've defined them as follows in the xsd, and built a wrapper class using the xsd tool.
<code>
<xs:simpleType>
<xs:restriction base="xs:integer">
<xs:enumeration value="123"/>
......
</xs:restriction>
</xs:simpleType>
</code>
<code>
[System.Xml.Serialization.XmlTypeAttribute(Namespace="TheNameSpace")]
public enum EnumType
{
/// <remarks/>
[System.Xml.Serialization.XmlEnumAttribute("123")]
Item123,
}
</code>
I can read/write the xml normally without problem. The issue comes when I want to reassign a value of EnumType, and use it later in the session.
<code>
xmlClassObject.EnumTypeValue = (EnumType)123;</code>
This assigns the value to the enum, and will save properly. The problem is that as shown in the debugger or created using ToString(), the value loaded from the file is "Item123", while the value I set in code is "123". Is this a bug in MSes code, or should I be setting the value in a different method? I tried creating the string "Item123" and assigning that, but the cast failed.

Is there a way I can use the code tags, and still have my XML survive?

Dear All,
I have a directory in E drive, which I want to share and allow full control to aspnet via C# programming.
I need simple code for it.
With Regards

You can make a call to the net command line application
net share sharename=c:\folderToShare
You can call this from C# using
System.Diagnostics.Process.Start ("net share myShareName=c:\\folderToShare");

This application allows multiple software developers to communicate about a piece of structured text such as
software code or HTML. *All code is automatically formated. Each users mouse movements can be seen by the other
users and the view is automatically scrolled as necessary to keep all developers looking at the same code at the
same time. *All mouse locations are ratioed to factor out differences of messenger window size, activity splitter
location, and screen resolution. *Users can identify themselves by a name/nick-name and a color. This name/color
show up under the users pointer so everyone can see who is moving each pointer. *Code highlighted on one users
screen is highlighted on all users screens. *Code pasted into the view is saved in a clipboard for all users to
recall without having to resend the code. *Code can be copied out of the view. *The Selection Search feature shows
a Top 10 matches list for any word highlighted in the code view.
Please go check it out. It has helped me and my team when talking about code sections or designs.

Any ideas on how to launch the default email client from within a C# application, attach a file, and specify a subject line and message body? I'd appreciate any input.

forgot to mention that I only want to fire up the Send window (equivalent to what's happening when you do a Mail -> New Message from within IE).

You could create a new process with the "mailto" command:
System.Diagnostics.Process myProcess = new System.Diagnostics.Process();
myProcess.StartInfo = new System.Diagnostics.ProcessStartInfo("mailto:admin@admin.com?subject=Subject text&body=Body text");
myProcess.Start();

Thanks! Is there ANY WAY to specify a file to be sent as an attachment? Seems like there has to be because I could right click on the file and select Send To -> Mail Recipient and I get the send email client with the file attached. Any help would be greately appreciated.

append &attachment="c:\temp\file.txt" make sure the file exists beforehand

|

This does not work. I don't think that mailto supports attachments. Any other ideas?

Don't know 100% for sure but I'm guessing
<br />
string maxVersion = String.Format("{0}.{0}.{0}.{0}", Int32.MaxValue);<br />
