Hello again!

Here I found a very nice solution with regex!

public bool IsValidIPAddress(string ipAddr) {
   string pattern = @"^([1-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])(\.([0-9]|[1-9][0-9]|1[0-9][0-9]|2[0-4][0-9]|25[0-5])){3}$";
   Regex reg = new Regex(pattern, RegexOptions.Singleline | RegexOptions.ExplicitCapture);
   return reg.IsMatch(ipAddr);
}

I don;t know the exact answer but this might help you ...

Create MS Word object
use the save as method of MS Word object, pass html as parameter

Hopefully this should be the approach

This is probably the only way, however I believe it is really a bad practice!
It relies that a correct version of MS Office with MS Word is installed by user, and depends on the interface provided by that specific version. I don't think there is another way however, since DOC format is proprietary, and theoretically only Word engine should know how to parse it.

I agree but thats the way you will have to tackle this problem else u might have to write some by yourself to parse a doc.

All the best !!

Let me also know if you tackle this problem

Does open office provide automation? I'm not sure what the OO licence says about bundling with non OSS apps though so this might not be an option.

What do you mean "in browsers"?

I can tell you how to do that from a windows form application which has a WebBrowser control on it. That has most of the functionality of IE. Isn't this what you want?

An simple example of how to do an automatic search on google:

Place a WebBrowser control on your form.
Use it's navigate method to load the google page:

MyWebBrowser.Navigate("http://www.google.com");

In order to access the controls on the webpage and use the you need to know what their names are from the html source of the page. If you take a look at google's source you'll see all the controls, and among them these two:

<input maxlength=2048 name=q size=55 title="Google Search" value="">

and

<input name=btnG type=submit value="Google Search">

The first one is the text box where you type the text to search and the second is the search button.

So, all you need to do is fill the text box and after that simulate clicking the "Google Search" button. Like this:

<br />
HtmlElement searchBox = MyWebBrowser.Document.All["q"];<br />
            searchBox.InnerText = "code project";<br />
            HtmlElement btnSearch = MyWebBrowser.Document.All["btnG"];<br />
            btnSearch.InvokeMember("click");

Hope this helps.

Have a nice day!

I forgot to mention. There's a very quick and easy way to find the name of the controls you need from a web page. It's called Firebug. It's a plug-in for Firefox. Just use it.

Parsing XML with XPath Navigator [modified]

Hi All,

While parsing an xml document using Xpath navigator how we can check whether a node has child nodes or not. Tried using both HasChildern and IsEmptyChild but no luck.

I should be able to differentiate between

<test>
<node1>No child</node1>
<node2>
<node3> child 1 </node3>
<node4> child 2 </node4>
</node2>
</test>

How to diff between node1 (no children) and node2 (which has children)

Thanks in advance.

Regards
Mahe

Has child nodes should work fine!
Check your xpath correctly, for best examples with xpath refer w3schools!

Hi,

Thank you for your response. My XML file is

<Countries>
<Country>
<Name> Singapore </Singapore>
<Address>
<State>IA</State>
<PostalCode>20</PostalCOde>
</Address>
</Country>
</Countries>

My Xpath is selecting country element. So how can i differentiate between name element and Address element.

Thanks,

Convert string value to a data type

swjam10-Apr-07 17:23

I have the following line of code:

sqlAdapter.SelectCommand.Parameters.Add(new SqlParameter(strParamName, strParamType, 10));

strParamName and strParamType are strings.
Now, the sig of Parameters.Add is as follows:
Parameters.Add(string, SqlDBType, int);

The value of strParamType is one of the SqlDBType's i.e. "VarChar", "Int", "Bit" etc.
How would I convert the value of strParamType to make it SqlDBType?

Thank you.

Well the first question I would ask is Why are you passing in strParamType as a string, can't you simply pass the SQLDBType instead, they are Enums afetr all. Otherwise you'll have to have a switch statement to select the correct database type from the string passed in.

Always look for the easy option Smile | :)

Thank you for the reply.

I read the parameters from a text file that is why I need to determine the type of the parameter from the string programmatically.
