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...

I am developing a vb.net app for displaying the pdf files or pages for readng. I have browsed the net the whole day but cannot find a dll for viewing the pdf on an app. Is there any free dll or any...
-
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.

Well like I said in my starter post, I want to pass a file path variable to a web service and I constantly get the 400 Bad Request error message. The reason is that the string has the...

I see noone is keen to assist me here. I decided to encode and strip the path
of these special characters, transferred it across to the server and re-assembled or replaced the characters again. This...

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.
-
Guys thanks a lot. I have managed to crack it now. The problem was that, since the data came from a database, the class properties and the data fields were not matching. But I thank you for guiding...

I have one foot in there. Thanks a lot guys. Just one last hurdle, I hope. When testing for data using:

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...

How do you write powers in vb.net?. For example, how do I write: 5 to the power 2? I am struggling to get answers on the net. Can someone help please. Thanks.

Well I don't quite get it tg. If a file is sitting in a folder you can do the pushing/pulling using ftp. But when doing a login that is not possible. Instead a message is sent to a method in the...

Yes, I want to use the service i.e. login and do other stuff. Let me admit that its my first time testing the web service between two computers. I did the ftp publishing because I am using the...

I did an ftp publishing of a web service. Now I want to do a login using the ff WebClient string:
I have tried high and low with no success. Please help me out. Give any directive or reference...

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...

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...
