Hello folks,
I am working on Delphi since more than a week now.
Since then I have been trying to consume a web service created in C# .NET using a Delphi desktop application.
Can someone please help me with the issue I have here:
My web service has two methods:
1. One doesn't take any parameters & returns a text data.
2. Takes a string parameter & returns a string data.
My problem here is, I can call 1st method without any problem, but when I call second method, I get nothing out of that method. Same two methods work absolutely fine in C# .NET.
Can you please help me out, I can't find any way out of it.

Hi,
if I understood you right the problem is, that the parameter you pass is null for the second method. Maybe there is a problem with filling the SOAP-request for the second method. Check the wsdl of your service, how the request must look like (especially the parameter) and then try to use a tcp-monitor to check if your delphi application puts the passed string in the correct field of the request.
I'm just guessing, so I hope this helps you a bit.
Regards
Sebastian

Aehm, well and the errors are? What kind of errors do you get? Compiler, runtime? Maybe the textbox and the label are not declared. Same with the getIDSimple-method.
|
|
|
|
|
haha well they were ---> are you missing a using directive or an assembly reference? and not in current context
but I knew I had all needed references/dll in my bin
I found out at work later in the day why, I should slap myself
they all started with lower case, I had uppercase 
(I have another problem I am posting soon, maybe I can get some help with this one)
|

|

Well, if you want any help you need to post the error messages and where they occur. Have you tried the simple solution of stepping through in debug?

hi,
plz tell me how can i modify the url from
xyz.com/page.xyz
to
xyz.com/page.html
I want to make sure that whenever a url is hitted with some page.<anything> it should be rewritten as page.html.
PS: I am using plain html files.
Thanks
Aditya

Well I'm sure you can do this:
Since you're using plain html files then when you save the file, in your example the save name would be 'page' ( resulting in xyz.com/PAGE.xyz )
Do This--> save the file as 'page.html' and upload to your ftp. It should come up on the browser as xyz.com/page.html
Example:
say the website is www.google.com
and the file name is 'probe'
normally it would show www.google.com/probe.xyz
(the .xyz is whatever you type the file in such as a simple .txt if using notepad)
just save that same file as 'probe.html' and upload to your ftp and it should come out as
www.google.com/probe.html
It's as simple as that if I understood correctly

Hey thanks for the reply,
however i think there is miscommunication.
Let me explain this issue to you -
I have my pages all ending with ".htm" so the default file is default.htm
However, i want to make sure, even if somebody hits "default.html" it should not go to 404 page instead it should be redirected to default.htm page. so the page wont appear broken for simple 'l' in the .html.
so i want to rewrite URLs ending with .html to end with .htm
I hope i am clear enough this time.
Thanks again,
Aditya

|

ok, Well in that case the only way I know how to solve such an issue
is to create a file called default.html and have it auto redirect to default.htm
that way whenever a user types either name both goes to default.htm
|
|
|
|
|
thank you...
well actually it was not just for one page.. i wanted it for whole site.. i have heard of the mod rewrite.. but i am not sure about the regular expression and the syntax that needs to be there for rewriting the URLs automatically for any page within the site.
Anyway thanks for your efforts!!!
cheers,
Aditya

Hi,
can you connect to the database by using the "Test"-button on the ODBC-Administration form?
Regards
Sebastian
P.S.: Maybe you could post the code you are using to connect to the db.

Give us some code, and the connection strings. Then we might be able to help, as of right now, there are about a million reasons as to why this isn't working.

Hi all,
we are calling a swf inside a asp.net page(.aspx), when I click the print button(in flash) it's not detecting the printer, it shows the message Detecting Printer...., but nothing happens. But if i call the same page inside a html page it's working fine. There is some reason to call the swf inside the aspx page.
I am not a flash action script programmer, am a .Net developer, the developer who done this work not here now. They askd me to fix this.
Suggest me how to fix this.
Thank you all.

I am not sure either, but since it is working on the html page, you could IFrame it on a simple html page, set the border to 0 and you won't even know it is there.

You need to have some code that handles the grid view PageIndexChanging event, much like the error says. Google for it...

Here is a simple question for everyone but me.
The purpose of this code is to send a feedback message to me, the webmaster.
The visual basic code is written on a code behind page for the page which has the blanks to fill in to send the webmaster feedback.
The code sends the message. However, it's ina loop. The Protected Sub Button1_click procedure starts, it does the SendMail procedure with no trouble, Does the end sub and then goes back to its beginning of Protected Sub Button1_click to send the message again. How do I get out of this loop?
Thank you for your help.

End Sub

There's no loop in the code you posted. What does the sendmail function do?
|
|
|
|

Ok, there is no loop in the code in the Basic programing technical sense. On the other hand why, after doing the End Sub of the Protected Sub Button1_click, does it go back to the first statement of the Protected Sub Button1_click procedure and proceed to do it all over again?
Here is a copy of the entire code behind page Page/History.aspx.vb. When I step through, statement by statement, it jumps over the Catch statements and does Finally and its statements and then End Try and then End Sub and then jumps to Protected Sub Button1_click, does the Dims and starts the Send Mail all over again.
I use ASP 3.5, Visual Web Developer Express 2008. The four Dims are there so I could be sure I picked up the four variables from the Display page. Once I know things are working correctly,
Much thanks for your help.
