Re: from .dbf FoxPro to MySql - Web Development Discussion Boards

I like to submit a request to a web service and wait for the response. I have to give web service a page name where I should the response. <asp:button postbackurl="SomePage"" runat="server"> but I am unable to find any reference to PostBackUrl in MVC. In other word how are we going to deal with PostBackUrl or how we can provide return CallBack page?

Not clear on what are you trying to ask here. You start by requesting a webservice on one end and then ended up asking postback url in MVC. Please update your question and clearly specify about your work and need.

Well I send a SMS (message) through a service provider, where server provider is asking me the web address where to inform back for the result as a success or fail.
You may look complete example at (Working example and you play it to understand it)
http://www.w3schools.com/aspnet/showasp.asp?filename=demo_prop_webcontrol_button_postbackurl
 <!DOCTYPE html>
<html>
<body>
<form runat="server">
Name:<asp:textbox id="TextBox1" runat=Server />
<asp:button id="Button1" Text="Submit"
PostBackUrl="demo_postbackurl.aspx" runat="Server" />
</form>
</body>
</html>

As you see asp:button has property PostBackUrl, but as far as I know there is no button implementation under MVC3. The service provider only take web address as a PostBackUrl to return the status of the MSM call.

I hope I explained well. Thank you very much for the reply.

Hi, I have a problem, I don't know how to convert .dbf in FoxPro to MySql using PHP. Who can help me? Smile | :)

Gday, I dunno how to do it either.

But Google does! Entering your thread title (only) yielded 84,000 results. Presumably one of the first 10 will suffice?

Here you go: from+.dbf+FoxPro+to+MySql[^]

hehehe..Thanx for your attention before Sir.
I know Sir, I have done it before..
but my code is not give solution..
It can't open the .dbf file..
it's error said that lenght parameter must be greater than 0.
what happen with it?

Thanx before.. Smile | Smile | :)

A sense of humour and polite. Nice! Thumbs Up | :thumbsup:

That's enough to get continued effort form me right now.

I don't know "what happen with it?"

Can you show the line of code that fails?

heheheh..thanx Sir..
this is the code Sir..
I don't know where is the wrong code,
because I think it's already right n it have used by another person n when I just try I can't..

sorry if u feel bothered.. Smile | :)

Hmmm. Okay - that was actually the class I was going to recommend you use.

Now then, the text "length" appears in that document 3 times - each of these are in the comments.

I also see that it doesn't include any other php files, so I can only deduce that the error message is coming from MySql itself. Its very difficult to tell, since you didn't copy/paste the exact error message. (I doubt the error message is going to spell 'length' as 'lenght' Poke tongue | ;-P

)

This makes me consider the possibility that there is in fact, nothing wrong with this code, and that the problem lies in the database structure.

Another alternative is that (& I don't know) perhaps the FoxPro database has a field with NULL in it and you're trying to insert that, but since there's no value, an empty parameter is being passed to mysql, rather than a zero or NULL value..

However, since the code has been around for so long, (at least since 2004) it seems unlikely that it still has an error.

I see that you've made this modification:

PHP

if (!file_exists($filename)) {
echo "<script>alert('Masukkan data DBF')</script>";
}

In the original code, there is an exit statement in that block, so that execution wont continue if there's a problem. In your case, it does! (continue if there's a problem)
I'd change that quick-smart!

PHP

if (!file_exists($filename)) 
{
        echo 'Masukkan data DBF'"
        exit;
}

I suggest that you add some more printf/echo statements to the class to let you know when execution passes certain arbitrary points. A good first location would be after the file has been read and then closed.

At least then you can know where processing gets to before failure - this lets you know which data is being processed at this point and dismiss or confirm that it's the data.

But in any case, often a quick way is to add more echo statements so you know where execution fails.

Good luck. Thumbs Up | :thumbsup:

thanx sir..

BINGO!

So what's the full path to:

dbf_class.php
DRBS.DBF
The file that creates the instance of the dbf_class

Also, is the cAsE correct for DRBS.DBF?
Is it drbs.dbf perhaps?

hi
Please I try to retrieve data from web services (soap) and must pass an ID in cookie http header I tried with java code (eclipse) but I can not I tried also with other tools tjrs but its not happening ...
I am beginner I really need a helping hand to find the error and the tool to be used

Thank you in advance

My prob is in the URL: I can not add it and how to add the "sid"on url (sid: is the username (cookie))

Could you not send it as a query string in the URL?
Sample: http://myserver/mywebsite/mywebservice.asmx?sid=mycookiename

Just a suggestion - please don't post so much of code here. you might be working for some employer and if he finds out that the code is being leaked on public forums you might get in trouble.

Post just the stuff that is causing the problem. always be discreet while giving code. make sure you don't violate the employes NDA in any way. we don't want you to get in trouble.

I wrote an article on creating a .Net REST service.

.NET REST service[^]

I hoped to re-write the REST aspects utilizing a .Net restful service open source project. I'm avoiding WCF, as it is counter-REST (light-weight/simple). I am thinking of something fluent, spring-like, convention over configuration. It needs to be robust, handle all the verbs, async, file transfers and auth/security.

I can't find anything at all. Anyone have any leads for a .Net library or Java libraries that could be ported? There may also be an opportunity to start an open source project.

Thanks,

Hello,

i want to make an attendance system in asp.net i have made two tables
1.attence_record (in which i have attendance record like record_id, date, class, subject)
2.raw_att (in which i have particular date and subject attendance)
record_id is foreign key in rwa_att.

now i want to create a grid view control to get the status of particular student.

i also need a dropdown for filling status. that is the main problem.

Use ADO.NET to get data from DB and use it for display in grid

Assuming, you meant dropdown in grid, this should give you some idea:

Now, try first what you want to do! You may find that it's not that hard. Formulate what was done by you that looks like an issue/not working.

Hi,

How can I redirect user based on thier compnuter language so if the page is English then redirect to www.mydomain.com/en otherwise stay on root www.mydomain.com?

You could try and base it on the 'Accept-Language' header that the browser sends to the website. This contains a list of preferred languages. See official W3 specifications[^] for more on how to use this header.

But make sure to always have an option for users to change the default language on the site, or you might get angry users that don't want english even though their computer indicates it is the preferred language.
