Hi,
I would be greatful if I could get some help regarding the following:
I'm a newbie at WebServices and I'm just setting up a simple service to get my feet web.
I used MS' web servive walkthrough as a template:
http://msdn.microsoft.com/library/default.asp?url=/library/en-us/vsent7/html/vbwlkWalkthroughBuildingWebServiceWithManagedCode.asp
So, when I run the service as they say to set it up, it works fine; returns the temp conversion as expected.
However when I add some Process code to the main method, like this:
// C#
[WebMethod(Description="This method converts a temperature in " +
"degrees Fahrenheit to a temperature in degrees Celsius.")]
public double ConvertTemperature(double dFahrenheit)
{
using (Process proc1=new Process())
{
proc1.StartInfo.FileName = @"c:\folder1\folder2\testapp.exe";
proc1.start();
}
return ((dFahrenheit - 32) * 5) / 9;
}
All the testapp.exe does is create a file locally. This test app works on its own.
So when I run this, nothing happens, the testapp doesn't run and the temp isn't returned. When I tweaked it some more, the app still didn't run and IE kept coming back with a page not found because the name of the method was being appended to the end of the URL, and that obviously doesn't exit.
So, does anyone know why this is not working as expected, am I missing something? It looks simple enough and I am running this straight on the server itself.
Any help is appreciated, thank you!

The account running the web service will need permission to execute the file. It also needs permission to create a file in the folder.

Is there a way to programmatically have a select box expand its list of options? If so, how do we do this?
Thanks
|
|
|
|
|
No. How the selection is done in a select box is beyond the scope of html and javascript. To have the options expand to a list is the most common way it's implemented in browsers, but there is nothing that says it has to be done that way.

Hi All,
This might be a really silly question but I have never attempted anything like this before, so please bare with me.
We are trying to create a web page that will take input data from a few fields (e.g. text boxes, drop down lists, ...) and write them to in a file format (e.g. XML, excel, ...) on the server.
Seeing that we have never done anything like this before, can anyone suggest how to this in the simplest manner or where to start looking?
(btw, we don't have .NET and the company won't spring for that kind of expense (we have VC6 though))
regards,
Rich

I would suggest tou write an html page that contains a form for the data you want to collect. When the form is submitted you need to process it in one of two ways:
1. You could use whatever server-side scripting language you have on the server to write directly to the file.
2. You could save the data to a database and then produce the file from there on a regular basis, again using the scripting language you have installed.
If you have no scripting language and you need to get up to speed with minimal cost i would suggest PHP. It totally depends on what server you are running etc etc, and how much traffic / data you need to process.

I created a simple web service that returns a dataset. It works fine when the service is on localhost. It properly accesses the database and returns a list of items. When the service is run on a server it returns nothing, no errors, just an empty dataset.
I have looked at the iis and the folder that contains the service is virtual and it is setup to support applications.
This is what is returned from the 'invoke' button when running the service on the servers:
<?xml version="1.0" encoding="utf-8" ?>
- <DataSet xmlns="http://tempuri.org/">
- <xs:schema id="Order" xmlns="" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:msdata="urn:schemas-microsoft-com:xml-msdata">
- <xs:element name="Order" msdata:IsDataSet="true">
- <xs:complexType>
<xs:choice maxOccurs="unbounded" />
</xs:complexType>
</xs:element>
</xs:schema>
<diffgr:diffgram xmlns:msdata="urn:schemas-microsoft-com:xml-msdata" xmlns:diffgr="urn:schemas-microsoft-com:xml-diffgram-v1" />
</DataSet>
It should contain the dataset within the xml. Any ideas?
Thanks in advance.

There is no obvious reason why the dataset would be returned differently just because it is run on a different computer. It is more likely that the dataset actually is empty, and that you should look for the error in the code that fetches the data instead.

It wasn't empty but the was a permission problem running it on the server. I would have expected that an exception would have been thrown but it just returned.
|
|
|
|
|
Yes, an exception should have been a result. This normally results in the exception being returned as a soap exception.
Do you have any code for catching exceptions that might have caught it and ignored it?

Could anyone tell me what do u mean by dynamic web page?????
|
|
|
|
|
Dynamic is a page that changes based on input from the user or information from a database. A normal HTML page is not dynamic. It is considered static because exactly what you write in the code will be displayed on the screen. ASP, PHP, and many other languages allow you to connect to a database and retrieve information based on what the user is looking for and "make up" a page right then. This is dynamic.

Hi, all
I am writing a script for protecting a website by password. Here are my script, but with some problems:
<SCRIPT LANGUAGE="JavaScript"><br />
<!-- Begin<br />
var password = prompt("Please Enter Password Here:")<br />
if (password == '123456') {<br />
}<br />
else {<br />
self.location = 'WrongPassword.htm'<br />
}<br />
</SCRIPT>
The problems are:
1. When I type in the website in the browser, it already loads all the content before it pops up the prompt to type the password, that means the protection is useless.
2. I have searched on web many different kinds of codes for password security. But, their codes usually divide into 2 parts, the head and the body parts. However, I can only have one column to enter the code. Therefore, I want to know what adjustments I need to make in the above code so that I can tackle the problem 1 stated above.
Thanks.

Your password page should redirect to another page when the password test passes. The same as you redirect to WrongPassword.htm if it fails.
However, you're sending the password to the client, which makes the whole thing futile. Your password page should work on the server, should use the database for multiple passwords, and should call a stored procedure so your code does not reveal the layout of your database with regard to password information.

Your idea is right on track. All that is missing is to tell the browser how to handle that the contents is larger than the panel.
Set the css style overflow:scroll; on the panel.

I haven written modules that generates a series XML files and a report in a number of HTML files which include and index etc. What I am having difficulty with is that we would like to be able to click on the name of one of the XML files in the report and get the browser to pop up the Save As dialog, so that it can be copied to a location other than the default.
This must be possible. I just haven't found out how as yet.
Happy programming!!

Hi there,
The extension .xml is a known type, so the browser by default will open it when the user clicks on the link pointing to the file. If you want to force the File Download dialog box, you may consider using the Content-Disposition header field. Instead of using the anchor, you basically use a seperate web page which is responsible for reading the content file of the xml and write out to the Reponse object, and you need to add the Content-Disposition field to the header of the response. With this field, you can suggest a filename which is displayed in the File Download dialog box.
|

Thanks for you're suggestion. I'll try it out.
Incidentally the file I generate does not use the .xml extension. It doesn't seem to matter what the extension is, for IE anyway, the browser checks that the file contains displable text so it displays it.
Happy programming!!

I must be doing something wrong as I can't get it to work. Could you suggest how the HTML is supposed to look.
This is not being done via a server.
Happy programming!!

The markup in the html file looks something like:
<a href="Download.aspx?filename=foo.xml" >foo.xml</a>
So you specify the web page in the href attribute of the anchor element instead of the foo.xml. Also, you might want to add the name of the xml file to query string so that it can be used later in the web page for reading the file content. In the web page, you programmatically add the Content-Disposition field to the header of the reponse.
In addition, you can also statically add the Content-Disposition field to the header in the IIS-snapin (Here, I assume you are using the IIS as your web server).

Ok, I know what you are thinking.  Why was this posted on the web forum? Well, let me explain.
I Have a DHTML text editor that I currently import Microsoft Word documents into via IE. The only problem is only text comes across currently. I came across info on MSDN that said images can be saved out of Word 2003 as bmp files. So far I can open the document, get a handle on each image, and copy them to the clipboard, but for some odd reason, probably my fault  , I can't seem to save them to the hard drive.
I've included the code below, perhaps you can assist, especially if you know MS VB.NET and VBScript better than I, which wouldn't be difficult to do.  Basically I get the image copied to the clipboard fine but then I don't seem to be saving anything out. Nothing fails, it just doesn't save. Any help would be greatly appreciated.
Sub ImportWordDoc()
On Error Resume Next
Set wApp = CreateObject("Word.Application")
wApp.Activate
wApp.WindowState=0
call wApp.Resize(400, 400)
Set wDoc = wApp.Documents.Open(document.all.FileToOpen.value)
wApp.Visible = true
For index = 1 To wDoc.InlineShapes.Count
inlineShape = ""
Set inlineShape = wApp.ActiveDocument.InlineShapes(index)
inlineShape.Select()
wApp.Selection.CopyAsPicture()
data = ""
Set data = Clipboard.GetDataObject()
If data.GetDataPresent( GetType( System.Drawing.Bitmap )) Then
bmp = ""
bmp = CType(data.GetData(GetType(System.Drawing.Image)), Bitmap)
bmp.Save( "C:\mybitmap" + cstr(index) + ".bmp" )
End If
Next
Call wDoc.Close(True)
call wApp.Quit(True)
End Sub
