And there I was thinking that the @ was overloaded (actually, I'm sure I remember reading it somewhere, clearly the author of said statement was leading me up the garden path). Bugger.

So to modify my original statement, you can specify a relative path such as:

path = "data", such that:

Directory.CreateDirectory("Data");

Would create a directory called data in the same directory the .exe is running in.

Not quite. It will create a directory under the current directory, which may not be where the .exe is running.

It causes the compiler to ignore any escape characters, such as the back-slash, in any string with it pre-pended.

Hi,

if your app needs a set of images (that for some reason cannot be embedded as resources),
then you must choose a folder carefully, then code accordingly.

Some examples:

C:\images
it is simple, but absolute paths may give problems; C: may not exist or not be accessible

folder where exe is
that's what you get automatically

one of the children of that folder
use a relative path such as "\images"; may be inside "C:\Program Files" and might be
write=protected !
BTW you can go upstream with \.. (but that in general is a bad idea; I do it while
developping to get to the project folder: \..\.. removes \bin\debug)

[userdatafolder]\theAppName\images
a much better choice; the system provides a location to put application data that is
user dependent; it typically refers to C:\Documents and Settings\theUserName\Application Data
you should append at least \theAppName and optionally some more grouping (say \images)

you get [userdatafolder] from Environment.SpeicalFolder.ApplicationData; so
I would suggest Environment.SpeicalFolder.ApplicationData+@"\theAppName\images"

Dynamic adding, editing & deleting data from a datagrid

Hi,
actually i am developing an application in which i had to dynamically create a datagrid, add columns, assign DataPropertyName to the columns.

if for example there are 2 columns in the grid than 2 textboxes are located at the bottom end of the grid which will contain the particular cell value.

inserting, editing is done from these textboxes. what i want is all the insertion, deletion or editing should be manipulated in the dataset or datatable & when i exit from the form than it will ask for "do you want to save these changes" if yes than the database is updated.

can anybody give some idea how to achieve so?

thanks in advance.

a detour around an "input-synchronous call"

Hi,

My C# prog uses global hooks to listen to what my mouse does in Google Earth (GE), and with the GE API I make GE do some things for me based on the mouse events. At a certain point when I click around in Google, I get this:

Retrieving the COM class factory for component with CLSID {8097D7E9-DB9E-4AEF-9B28-61D82A1DF784} failed due to the following error: 8001010d.<br />
<br />
Error Code: 8001010D<br />
 "An outgoing call cannot be made since the application is dispatching an input-synchronous call."

So I think it has to do with that I am asking GE to do two things at a time. Is there a simple trick to avoid this? A timer??? Threading?

I'm still somewhat a beginner Wink | ;)

Serialize a web serive into a c# class

Hi
I am having a nightmare trying to convert a web service call into a c# class so i can serialize the call.

I am trying to serialize the GetUserCollectionFromGroup Sharepoint 2007 web service

here is the XML although i do not know if this is correct as i found it on the web

<code>
<?xml version="1.0" encoding="utf-8" ?>

<dfs:myFields xmlns:dfs="http://schemas.microsoft.com/office/infopath/2003/dataFormSolution" xmlns:s0="http://schemas.microsoft.com/sharepoint/soap/directory/" xmlns:my="http://schemas.microsoft.com/office/infopath/2003/myXSD/2004-03-16T06-17-54" xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<dfs:queryFields>
<s0:GetUserCollectionFromSite>
</s0:GetUserCollectionFromSite>
</dfs:queryFields>
<dfs:dataFields>
<GetUserCollectionFromSiteResponse xmlns="http://schemas.microsoft.com/sharepoint/soap/directory/">
<GetUserCollectionFromSiteResult>
<GetUserCollectionFromSite>
<Users>
<User ID="1" Sid="S-1-5-21-3593225548-2099380924-3969701235-500" Name="User1" LoginName="login1" Email="user1@users.com" Notes="" IsSiteAdmin="False" IsDomainGroup="False"/>
<User ID="2" Sid="S-1-5-21-3593225548-2099380924-3969701235-1145" Name="User2" LoginName="login2" Email="user2@users.com" Notes="" IsSiteAdmin="False" IsDomainGroup="False"/>
</Users>
</GetUserCollectionFromSite>
</GetUserCollectionFromSiteResult>
</GetUserCollectionFromSiteResponse>
</dfs:dataFields>
</dfs:myFields>

</code>

I have tried using the xsd.exe file to convert it but i get the following error

Error: There was an error processing 'C:\InfoPathUserListDummyData.xml'.
- The same table (GetUserCollectionFromSite) cannot be the child table in two nested relations.

Please can someone help

Thanks in advance

If you add a web reference to the web service Studio will handle all that for you. If you really want to manually serialize, try Skeleton Crew[^], XSD.exe is next to horrible.

Try code model generation tools at BoneSoft.com.

Are you having problems parsing the xml?

Manually you can do it:

XmlDocument d = new XmlDocument();
 d.LoadXml( ... );
 XmlNamespaceManager x = new XmlNamespaceManager(d.NameTable);
 x.AddNamespace("xml", "http://www.w3.org/XML/1998/namespace");
 x.AddNamespace("dfs", "http://schemas.microsoft.com/office/infopath/2003/dataFormSolution");
 x.AddNamespace("s0", "http://schemas.microsoft.com/sharepoint/soap/directory/");
 XmlNodeList list
     = d.SelectNodes(
         @"
         /dfs:myFields
         /dfs:dataFields
         /s0:GetUserCollectionFromSiteResponse
         /s0:GetUserCollectionFromSiteResult
         /s0:GetUserCollectionFromSite/s0:Users/s0:User", x);

This will get the list of users.

Using SMTP for sending emails

Hello, I'm developing an application that sends an email via smtp. I work in XP professional and C#. I'm using the library System.Net.Mail for this. But I can't send messages, the code:

public static void SendEmail(string srv, string from, string to, string usr, string pwd)
{
MailMessage oMsg = new MailMessage();
MailAddress send = new MailAddress(from);
MailAddress rcpt = new MailAddress(to);
oMsg.To.Add(rcpt);
oMsg.Sender = send;
oMsg.From = send;
oMsg.ReplyTo = send;
oMsg.IsBodyHtml = true;
oMsg.Body = Functions.GenerateEmail();
oMsg.Subject = "Prove";
SmtpClient smtp = new SmtpClient();
smtp.Host = srv;
smtp.Port = 25;
smtp.Credentials = new System.Net.NetworkCredential(usr, pwd);
try
{
smtp.Send(oMsg);
}
catch (SmtpException exc)
{
MessageBox.Show(exc.Message);
}
}

But an exception is generated, the server wasn't founded.

I prove the same in Windows Vista Home Premium and the same code sends the email.

I need a solution, thanks!!

The secret is in the error message :P It can't find the server.

Have you got a firewall or something else that could be blocking it? your usrey ou have the right server address?

Hi,

in my experience sending mail only succeeds if you have a mail client (Outlook, whatever)
that is running. Maybe that's the difference between your Vista and XP machines ?

Hi, thanks for the response.

In both machines I have a mail client (Outlook). And the direcctions, user and password are correct. I prove to disable the firewall, and enable with the exception of smtp, and doesn't send.

There is only a difference, when I test the connection to the mail server, within open the outlook, the vista machine connects and the xp pro machine doesn't connect to the server because it can't find the smtp server.

Could be a problem of the configuration of windows xp professional?

Thanks.

If Outlook does not work on your XP machine, there is a problem with the configuration,
and not with your C# code. I'm not a mail specialist.

Is it your own smtp server you are using, or the server supplied by your ISP? If it's your own, is it in the same local network as your computer? If not, does your ISP allow sending mail with any other server than the one that they supply? (It's common for ISPs to close port 25 to prevent spamming.)

Hi, my company has a domain supplied by a ISP, and offers mail service. I try to send an email using the smtp of this domain to other user of other domain. And I think that the configuration of the mail is good because in Windows Vista the application sends the message. But in xp proffessional I have the problem that I have explained before.

Can you even ping your mail server ip address from the XP Professional pc ?

Also do you have the SMTP Service installed and running on your XP Professional PC ? SMTP Service can be installed via Control Panel -> Add Remove Programs -> Add Remove Windows Components -> IIS Components
