Well let me thank you very much for your help. Yes I was not sure if it is possible to do formatting of the datetime data in the sql query statement. I understand now that it is not possible and I...

Your replies are correct and I understand them well. However, I do not want to store data in the variables, unless it is impossible not to do so, which I doubt. The main reason is that I pull huge...

Yes, if myDate was a Date variable your answer would work. However, it is not a Date variable. I apologise for not clarifying that. MyDate is the Date/Time name for a field in the data file. In the...

The first choice is the pdf format because the text is presented in it. However, if it proves to be cumbersome and not the best solution I am willing to go with what you advise to work best. I was...

The service simply saves the data/string in the database. It pulls it out and send it back on request by the client.

I see noone is keen to assist me here. I decided to encode and strip the path

Yes, after grabbing data from the database, I first serialized it into the json string and the transferred it to the client for deserializarion. Data can't just be deserialized if not serialized.

I have a question that requires a bird's eye view of this topic, since I am a newbie on WCF. I retrieved data from the database and serialized it into a valid json string. I set the service-side...

I have located an error. It had nothing to do with the database. I had forgotten to update a select statement condition. I feel very silly as always. Thanks for attempting to help, jmc et al.

Yes, you are right. The data kept on piling in the table. What is happening is that in the other tables I can write,update and read daata but in this one table I can only write data. I did not set...

Something strange, to me at least, is happening here. I embedded a database with few tables. When I write data to the tables it persists in others but it always disappears in one table. What can...

Oh, sorry! I meant to say, 'Many thanks, BB'. You really helped me out.

Exactly what I was looking for. I helped me a lot. Many thanks.

A very good answer. Thanks a lot. I only need the Web Developer here and it can't be sensible to buy the whole package, which as you said, is very expensive for starters. What could be a go around...

I have been using the express versions of vb.net. Now I need to publish a web service. I discovered that the express version (2010) does not have the publish functionality. Is there any other...

Would you be kind to give an example. How do I generate and use the address? I am not that into the website development. Thanks

I use the ff string to send a request call to a local server and it works fine:

Advice taken. I dropped the idea,selected all the fields and filtered out the NULL columns in a datatable. Thanks for your valuable input.

Thanks jc et al. I did notice that a couple of posts declared no possible query for this. However, developers think all the time. I will take your solution as final. I will try it and see if its...
