If your ComboBox is set up properly, the ValueMember property should be the Primary Key for that company. All you then need to do is to pass that as a parameter to a SQL Query to retrieve the address.

I strongly suggest you buy a book and read/work through a it. As soon as you state you achieved something using a wizard then we know you will probably not understand the answer. You need to get some understanding of programming and data manipulation, not just following the wizards.

Wizards are great for users they are disasters for developers, they allow you to create simplistic solutions with no real knowledge of how it is achieved.

I'm not able to get the body of the mail.
Below is the code snippet:

MAPI.Session oSession = new MAPI.Session();
Object vEmpty = Missing.Value;
oSession.Logon("OutLook1", vEmpty, false, false, false, false, vEmpty);
MAPI.Folder oFolder = (MAPI.Folder)oSession.Inbox;
MAPI.Messages oMsgs = (MAPI.Messages)oFolder.Messages;
MAPI.MessageFilter oFilter = (MAPI.MessageFilter)oMsgs.Filter;
oFilter.Unread = true;
MAPI.Message newMessage = (MAPI.Message)oMsgs.GetFirst(oFilter);

while (newMessage != null)
{

string text = newMessage.Text.ToString();
//text is coming as blank.

newMessage.Unread = false;
newMessage.Update(true, true);

newMessage = (MAPI.Message)oMsgs.GetNext();
}

Thanks,

How to translate Win32 error codes

I googled for the better part of half an hour, and come up with nothing. Given a win 32 error code, how do I get the corresponding error message? FormatMessage() is what I would've used in C++. I'm assuming this can be done without P/Invoke voodoo.

Hi,

you can use a little P/Invoke to access FormatMessage, this is the code I normally use:

using System.Runtime.InteropServices;		// DllImport

public static string GetSystemMessage(int errorCode) {
	int capacity = 512;
	int FORMAT_MESSAGE_FROM_SYSTEM = 0x00001000;
	StringBuilder sb = new StringBuilder(capacity);
	FormatMessage(FORMAT_MESSAGE_FROM_SYSTEM, IntPtr.Zero, errorCode, 0,
		sb, sb.Capacity, IntPtr.Zero);
	int i = sb.Length;
	if (i>0 && sb[i - 1] == 10) i--;
	if (i>0 && sb[i - 1] == 13) i--;
	sb.Length = i;
	return sb.ToString();
}

[DllImport("kernel32.dll")]
public static extern int FormatMessage(int dwFlags, IntPtr lpSource, int dwMessageId,
	int dwLanguageId, StringBuilder lpBuffer, int nSize, IntPtr Arguments);

Thanks.

I had that one nailed down, but I felt an urge not to use it. Every time I see P/Invoke-stuff, I feel a cold chill running down my spine. Unsure | :~

I don't know any alternative, some holes in .NET need to be filled with P/Invoking old stuff. I just keep those in a separate class of mine.

Hi,

do you use an external assembly for your windows service. If yes, you need to register that assembly in the GAC so that the service can access it.

How to load entity properties conditionally

Vikas Misra(TCS)30-Sep-09 1:24

Vikas Misra(TCS)

30-Sep-09 1:24

Hi,
Suppose i have an entity class which belongs to version table in the database having following properties for the fileds(columns)
#region Properties
private string _Program;

public string Program
{
get { return _Program; }
set { _Program = value; }
}

private string _AllowVersion;

public string AllowVersion
{
get { return _AllowVersion; }
set { _AllowVersion = value; }
}
#endregion

Suppose in a method i need to pass only one property so i will have to intitalize Entity class of version
which will have two properties but i need only one.
Do we have any way to tell version entity class that only load AllowVersion property only while initializing version entity and discard rest of the properties i.e my VersionEntity object must have only
one field.

I guess the only possible ways could be attributes or reflection. If possible please provide code snippet
to achieve this.
Is it possible to do this without performance cost??

Thanks In Advance

If you launch your program from the Program Files folder I don't think you're allowed to write to that directory in Vista.

I think Microsofts policy in Vista and 2008 Server is that you shouldn't write to the Program Files folder (except at install time). Simply choose another folder to store that file (for instance another predefined folder found in Environment.SpecialFolder). But as someone else wrote, do you really want to store a password in plain text like that?
