Hi friends,

Am having a grid with TextBoxColumn in it..There a combo is placed for selecting the value for the textboxcolumn...

My Grid looks more like a table in the design view of MS Access..
Similarly,there are 3 columns ..one for FieldName,sec for Datatype and third for description...

In Access,when we select the datatype from the dropdown list and move to the next row,the datatype wont change even if we move through various rows up and down..

In my appln,after selecting and moving to the next row,and again back to the prev row(to tht part col),the selected text in the combo changes to that row(tht col) from which v r moving..

Kindly help me...

Thanx...

Hi All,

the follow code will be run normally in WindowsApplication:

string userName = "a"; Confused | :confused:

string userPass = "a";
string address = "192.168.18.145";
int port = 8080;

WebProxy myproxy = new WebProxy(address , port);
NetworkCredential credentials = new NetworkCredential(userName, userPass, null);
myproxy.Credentials = credentials;

WebRequest rqt = WebRequest.Create(this.textBox2.Text.Trim());
rqt.Proxy = myproxy;
rqt.PreAuthenticate = true;

WebResponse rsp = rqt.GetResponse();
System.IO.Stream stream = rsp.GetResponseStream();
System.IO.StreamReader reader = new System.IO.StreamReader(stream);
this.textBox1.Text = reader.ReadToEnd();

stream.Close();
reader.Close();

but in the SmartDeviceApplication,,it will cause the problem :
The response did not contain an end of entity mark.

Can you tell me why and how to solve the problem??
Thank you !!

I have an MDI parent form "formMAIN" with the following code:

public formMAIN()<br />
{<br />
  InitializeComponent();<br />
  // blah blah blah<br />
  LoginForm loginForm = new LoginForm();<br />
  loginForm.ShowDialog();<br />
<br />
  if (LoggedUserName != "")<br />
  {<br />
    this.Text += " [" + LoggedUserName + "]";<br />
  }<br />
  else<br />
  {<br />
    // problem area... I want to close the main form if login failed...<br />
    //   IE... LoggedUserName will be ""<br />
  }<br />
  ...

The loginForm connects to the database, checks for matching user name and password and sets the formMAIN's static variable "LoggedUserName" if a match is found. I placed it in the constructor of formMAIN so that it would appear first.

I want to be able to close this main form immediately if the user closes the login form or clicks the "cancel" button on it... IE.. LoggedUserName will be blank when the focus returns to the formMAIN.

I tried "this.Close();" as well as Application.Close(), but it doesn't work. I'm guessing this is because it's in the constructor for the form, which obviously is not yet completely instantiated. I can't put it in the initialize area for the same reason.

I need some way to automatically perform the this.Close() operation 'after' the formMAIN completes initialization if the LoggedUserName value is still "" (IE.. failed log-in or user canceled the login form). How can this be done with the least amount of code?

Try calling

Environment.Exit(1);

WARNING: I'm not sure if this is the right way to do it, but it seems to do the job. You might want to see if somebody else comes up with a better solution.

Cheers,

Try putting your code into the form's Load() event instead.

Isn't an ocx a COM control ? If so, you can reference it using COM.

Right click on the "Toolbox | Windows Forms" and select Add/Remove Items.
Select the COM Components tab at the top. If the activeX is registered on the system it will be in the list. Select it and you will find it in the Toolbox list.

Hi friends,

I have to open a text file in with .txt extension..

For this ,am using oledbConn,oledbCommand,oledbReader to read the text file...

I can retrieve the files with their name as "File1.txt","test.txt" etc(as normal filenames)...but if i try to retreive file of name as "test.test.txt","sample.text.txt"....that is,if there is "." in the name of the textfile other than what we use for the extension(.txt),...i could nt retreive...

It displays exception...

Is it possible to retreive the textfile names like this?

Kindly tackle this...

Thanx

Jimmy

You can use System.IO.Directory.GetFiles to find files in a directory, and a StreamReader to read a text file.

Why do you need to use the same method when reading from completely different file types ?

Google for 'read text file C#' and see if you find one example that says to use oledbreader.

I'm understanding that it's sometimes working for you, I'm saying that if you get on the web and look to see what other people do, that no-one uses this class to read text files, a totally different class is provided for doing this.

Ask whatever you like, but do it in a new question, so that if I can't answer, others can see what you're asking about.
