you'd need to use p/invoke. Why would you want to ? What do you need that GDI+ won't do ?

Regular Expression problem

ImageMagik does that ? OK, I didn't know that. In that case, p/invoke is your best bet, there are articles here on CP about it.

I have a following regex in my program

01          private void myMethod
02          {
03            string strInput = "http://www.yahoo.com/";
04            string p = strInput;
05            Regex myRegex = new Regex(@"http://(www\.)(?[^\.]+)\.com", RegexOptions.IgnoreCase);
06
07            MatchCollection MatchList = myRegex.Matches(strInput);
08
09            StringBuilder sb = new StringBuilder();
10            sb.Append(MatchList.Count + " Matches found\n");
11            sb.Append("==========================================\n");
12            rtbOutput.Text = sb.ToString();
13           }

But when i run the program i receie the following error

An unhandled exception of type 'System.ArgumentException' occurred in System.dll
Additional information: parsing "http://(www\.)(?[^\.]+)\.com" - Unrecognized grouping construct.

What am I doing Wrong?

If I'm not mistaken then (? marks the start of a named group (see named group in MSDN).

Why do you have the ( and ) anyway?

Take the '?' question mark out of the group and put it in front of it, actually marking the fact that (www\.) is optional.

I feel like I've answered this one three times today.....

Just use the RegisterClientScriptBlock method on the page class to write javascript into the page, and build a string in your code behind that creates the variable.

Yes you can use RegisterClientScriptBlock...

but if you put some dynamic values in javascript you can use this one also..very easy and stright forward.

string str="Some Dynamic String";
Response.Write(" var ServerStr="+str+" ");
cheers Smile | :)

Some problems with this

1 - you didn't put the variable in quotes
2 - Response.Write always puts the text at the top of the page, above the head tag, this is bad.
3 - RegisterClientScriptBlock lets you stop a script from being inserted more than once.

Ideally, if you want full control of the text's location, you should put it in the aspx, or put a literal control in the aspx that you can set to contain the script.

Merging Datasets

Hi,

my situation is that I am creating an updater for my application that updates a reference library in the database.

I have a master library and a client library. I basically want to be able to compare the master library with the clients library and update where necessary.

I could achieve this with the merge datasets, then call get changes and update the database. However what I must avoid is that the client may have made changes to their library and I don't want to override there specific changes with the master database.

Any ideas how I might acomplish this?

Thanks

Paul

I suggest to use an approach of your own, not the Merge method. The Merge method updates the values in the target DataSet.

Why not just loop through all rows in the Master DataSet, look for a row in the CLient DataSet with same id (or something similar) and if none is found, then load the master row to the client DataSet.

Methods to use:
- foreach () for looping over Master DataSet
- FindById(id) for searching the row in Client DataSet (assuming it's a typed DataSet with PrimaryKey id)
- LoadRow(row) to load row into Client DataSet

Happy Programming

Thanks for your reply.

I think we are going to stick with our XML approach but we were wondering if an object based approach was feasible.

With the XML approach we do the following:

1)Generate XML on the master database (contains updates/changes)
2)Then compare the XML with old XML generated on the last update.
3)Work through the XML and outputting where any changes are discovered.
4) The out put contains information on the row and particular field that is different
5)We can then call SQL to update the specific fields that have changed as well as insert/delete rows where appropriate.

Is there any easy way to do that using objects. Or is it best to stick with the XML approach?

Regards

Paul

Hello,

Thread.Sleep will do so!

An alternative to Thread.Sleep is using a Timer.

MessageBox.Show doesn't have functionality to close the form. Write your own form, and have a method you call which shows the form modally, and runs a timer, then it closes itself.
