Good day,
I have created a webservice in visual web developer express.
"http://localhost:50198/ScanShip.asmx"
It has a function:
"http://localhost:50198/ScanShip.asmx?op=CheckSerial"
How would I now consume this webservice from Visual Basic .net.
You cannot create a webservice in visual basic 2008 express and all the documentation explains how to set up the webserivce and then consume it in the same project.
I only want vb.net to consume an existing web service.
Any help would be appreciated.

You need to add a reference to it from your VB.NET project.
Right-Click the Project in the Solution Explorer and select Add Service Reference.Steve Jowett

Thanks. Just what I needed.

I am developing an assessment in vb.net and on the last page, I want to be able to add a signature. Does anyone know how to add or attach a signature in vb.net? Any advice would help. Thanks.
|
|
|
|
|
Well, if the signature is saved as an image, a picturebox would do nicely...
|
|
|
|
|
But when the program is running I want to be able to attach the signature and submit it to a database. A picture box is just used to display an image correct?
|

You didn't say this in your original post.
What constitutes a "signature"? Is someone signing a creditcard pad? Is there an existing image in a file somewhere? Is it a digital signature key? What??
But, in any case, you'd have to get the image and data and write it to the database, just like anyn other binary blob object.
I can't give any details because you haven't given any about the problem

Yes there is an existing image in a file somewhere. The program I am writing is an assessment which is simply filling out the forms and writing to the database and the last page requires a signature.
|
|
|
|
|
OK. You're obviously not the first person to want to store an image in a database. So, Google for "insert image <insert database="" engine="" here=""> database vb.net". There's tons of examples.

I have an interesting problem. I store my program settings in an XML file. When the program first starts I check to make sure it exist using
If Not File.Exists(m_SettingsPath) then
Throw New FileNotFoundException(m_SettingsPath & " could not be found.")
End If
Every time I run the program it throws an exception. The file absolutely exist in the correct directory, and I even confirmed this by enumerating all the file in the directory and it was found. In addition, in the following lines of code the XmlDocument object can open the file without any errors. So I can not figure out why the File.Exists method can not find the file. Any ideas?

What does m_SettingsPath contain at the point of checking the file exists?Steve Jowett

When I step through the code it contains:
"file:\C:\Documents and Settings\dmarciano\Desktop\Programming\JBX2JBN Suite\JBX2JBN IV\JBX2JBN IV\JBX2JBN IV\bin\Debug\Settings.xml"
It obtains this value by:
m_SettingsPath = App_Path() & "\Settings.xml"
Where:
Public Function App_Path() As String
Return System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetExecutingAssembly.GetName.CodeBase)
End Function

The documentation on File.Exists() clearly states:
"The Exists method should not be used for path validation, this method merely checks if the file specified in path exists. Passing an invalid path to Existsl returns false."
Do you really think your string literal is a valid file spec?

I've always used the File.Exists() to check if a file exist before I try and open it. Is there a better way to do it?

that is good, provided you give it a VALID file path, which you didn't.

That does not make much sense as there are other reasons why opening a file may fail, e.g. file being in use.

I did provide it a valid path though. I checked this by setting a break point and copying the value of m_SettingsPath and putting it into Windows Explorer bar and the file did open so the file path is valid. And the file does open and can be read later in the code if I remove this check.

No, you didn't.
Something that starts with "file:" or "http:" may be fine for Explorer, it isn't a valid file name.

Your answer makes it to easy for him ... he will have no fun while searching the error

| Validate the Path first with Directory.Exists, this will first ensure the path is valid. I would also output the full path and file name to the debug window, just to check there are no invalid characters like a double backslash. Steve Jowett

Hi,
I have few user defined functions written in vb script.
I want to convert these functions into .dll.
Can anyone help me on this regard.
Thanks,
Karthick.M

There are some differences between VBScript and VB and more so VB.NET.
You will need to recode the VBScript into either VB or VB.NET.Steve Jowett

You don't. VBScript does not compile down to native code, so there's no (standard) way of doing this. You MIGHT be able to find some compiler out on the web that will, but I seriously doubt it.
You'll have to rewrite your code in either VB6 (not recommended) or VB.NET (highly recommended).
Also, what are you going to be using this .DLL for?

Thanks Steven & Dave,
I have all user defined function in .vbs format, I want to convert it to .dll so that I can make a single executable exe with this dll.

OK. What part of "You can't do that with VBScript" is difficult to understand?
We've already told you what your options are.

I Understood that,
But I replied for your below question
