Attempting to use the amazon API to obtain product data and currently failing miserably. Getting the following error: (The HTTP request was forbidden with client authentication scheme 'Anonymous'.) Anyone care to point me in the right direction or provide a link to good example of the API usage?

I'm trying to figure out a way to download multile images from Amazon. I can currently download either the small, medium or largesized images by themselves. What I want to do is to download all three sizes at once. How can I do this?

Right now i have a form in the VB where there are 2 combobox in it. user can choose from a range of products that comes together with some description and these are to be stored in a database table.. when i retrieve these data from another form in VB, i'm only able to retrieve the first product and it repeat e same product in my second textbox.
View 6 RepliesI have 2 datagrids. One to show Product information and another for Product purchase details entry. Both share the same dataset. The dataset (ds) is filled up with columns from 2 table
ProductMstrTbl : ProductID, ProductName..
ProductDetailsTbl: ProductID, PurchaseDate, Amt, BalanceQty..
DataSet(ds) : ProductID, ProductName, PurchaseDate, Amt, BalanceQty.
The problem is that: Showing from dataset or entering new records into the dataset is no problem, but am not able to save the modified dataset into DataBase. SqlCommandBuilder failed to generate the corresponding INSERT, UPDATE command as the dataset has multiple base tables.
I am looking for a free utility or way to protect my software by requiring a Product ID (Which will be created when a customer requests a paid license) to use the application after a demo version. Like most shareware apps.
View 2 RepliesOddly enough, I've worked around this issue, but it's still annoying me. I worked around it by sending too-long writes, with padded zeroes; the code works but sends a few hundred unnecessary bytes. Specifically, I need to send exactly 992-byte packets instead of 7 or 19-byte packets
View 2 RepliesI'm trying to obtain data from a dll, but I do not know how to do it.My code is:
'Function

Public Declare Function GET_PRODUCTS Lib "EbmPapstFan.dll" (ByRef ruta As String) As Long

This isn't a mistake with the path because Int_A is 0. In addition, GET_PRODUCTS gives me the number of products that software has.The manual say that this function also has string character output.I don't know how obtain this other string character output.
I am trying to read data from an excel sheet but there is an exception saying that no value given for one or more required parameters which I don't understand. Here is my code upto where the error is pointing to:
Dim MyConnection As System.Data.OleDb.OleDbConnection
Dim DtSet As System.Data.DataSet
Dim MyCommand As System.Data.OleDb.OleDbDataAdapter
[code]....
The exception points to that last line MyCommand.Fill(DtSet) which shows me that there is a problem with my select statement. Previously my code reads the data and displays it without the where clause in the select but when I added the where statement so that it can only read data from rows where the column I has a value equal to 176, it instead gives an exception that shows that some required parameter is missing a value?
Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

I have a main form, and some sub forms, and each sub form can have some sub forms. When I have multiple sub forms open, and I try to get data from the parent form, it returns the data from the wrong parent form.For example I have two instances of Mainform.subform running. If I do something like this in a child form of one instance of the subform. It returns data from the other subform.
dim l = Mainform.subform.listofdata

I am using My.Computer.Network.UploadFile(arg1,arg2,username,pass) & sometimes it returns an error to me about not being logged in?I keep using IE & such to visit the ftp'd pages & even login & logoff the ftp site server at times, but seemingly randomly it will fail, even if I use try catch statement, it seems to keep wanting to fail till i go back to IE & go to a webpage on the server or log back in to the account management through IE.
Should it not be authenticating & working correctly each & every time regardless unless the server can't be reached? Why is it wanting to fail SOMETIMES when closing these webpages/logging out on IE only, why is this seeming to have any bearing on this failing in VB.

After roughly 250 iterations of about 5-6 WebRequest per iteration, the app hangs and starts hitting the WebException "The remote name could not be resolved: 'hostnamehere' ". WebPages also don't load through my browser when this happens, I have to close the app for my internet to work again. This app is multithreaded and I was testing with 100 threads (in a threadpool, MaxThreadCount set to 20, addressof the sub which performs the WebRequests). A test with 20 threads yielded identical results - Same WebException also right around 250 iterations processing the same sub. I have tried setting the ConnectionLimit of the request to the thread count with no luck.

I have a function (GetData) that parses a SQL string, makes a connection to a SQL Server and dumps the result to a DataTable. It works perfectly on a series of SQL calls I have. I have new query I have added and now the function balks at the adapter.Fill(table) call. I do not understand why the call fails. The SQL portion works fine when run directly against the SQL database (Management Studio). I am thinking the fuctions not capable of dealing with the subquery somehow, just not sure why.

I am trying to test for the existence of a file on a web server using the GetFileSize method.
When I use code I found at BOL, the code never finds the file. It always returns a 550 code.
Howver, if I preface the code with a Request to get a DirectoryDetail listing, then the GetFileSize method works fine.I must be opening something and not closing it. Whatever it is, is then available to the GetFileSize method. But I cannot figure this out.

I created a simple service that does some inventory and records the data to a MySQL server. The service starts just fine when told to from the services administration panel. However, it will not on computer bootup. I get the famous error.
The InventoryService service failed to start due to the following error:The service did not respond to the start or control request in a timely fashion. I've read that logs can be a problem, so I disabled the autolog...but that didn't solve any problems. I believe it has something to do with the user not already being logged in and attempting to connect to a remote database. So, I added a function to check for internet connectivity before executing any inventory methods or SQL queries. This did not fix it either.
EDIT: I also am receiving the following error in the administrative logs. I create the service dependant upon the Tcpip service, but it still fails.A timeout was reached (30000 milliseconds) while waiting for the InventoryService service to connect.
We have a legacy setup that creates pdf's on the fly based on client info. I can follow everything through where the process gathers the info and everything runs normally, until it gets to the doc.Form.FlattenFormFields then it goes in to limbo.

View 1 RepliesI'm using the ASP.NET Membership provider and using the Password Recovery control to reset the user password if they forget it. On the whole it all works fine, but with one catch when it comes to validation.I have expanded the PasswordRecovery control out to use the template feature to customise the appearance, which is all fine. I have set the user lookup error handler using:
OnUserLookupError="PasswordRecovery1_UserLookupError"
in the opening tag and if I load up the page, type in some junk name and click submit this fires as expected, in all browsers. The snippet of VB code makes an error div visible and sets some text.However, if upon loading the page for the first time I type a duff name into the username box and hit the enter key to submit the form, in Internet Explorer (version 8), the UserLookupError event fails to trigger. It triggers just fine in Chrome or Firefox, just not in IE. I know it's not a focus issue on the form, as I can see the form is being submitted.If I click the submit button first, then following that hit the enter key it does fire, it's just that first time it doesn't, and only in IE.Also to add that if I set breakpoints in the VB code to check to see if the page is being submitted, I can see the Page_Load event fire when I hit the enter key, but not the sub PasswordRecovery1_UserLookupError.

I am working on a Tag system for a news page designed in ASP.NET. For the system I require a TagExists method to check for tags within the database. The stored procedure I have written is below.
ALTER PROCEDURE [dbo].[Tags_TagExists](
@Tag varchar(50))
AS
BEGIN

I have tried switching the procedure to return 0 if the tag exists and 1 if it does not and it still returns 0 despite the exact same testing conditions. I have also returned the actual select query and it has complained of the Tag "news" (my test item) not being an int on execution showing the select itself is definitely properly formed.
