Dataset With A Bunch Of Product Info?
Aug 12, 2009
I have a dataset with a bunch of product info. What I really need to do is send each product individually through a file stream using serialization/deserialization into a web service. I tried for testing purposes to write the dataset to a file, but I don't know how to write each product to a different file.
Dim oProduct As webservice.Product = New webservice.Product()
For Each DataRow As DataRow In DataSet11.Yahoo.Rows
oProduct.MfrName = DataRow("manufacturer").ToString
[code].....

I have a simple app where I am trying to fill in a bunch of fields (Client Info). The controls are bound to a DataSet (ClientDS and the table I need is Clients). I have a data navigator which should allow me to scroll through the selected info for each client. I have the following code
[code]...
The problem is ... it won't accept the Clients in (ClientDS.Clients). ClientsDS is the existing dataset I've created and to which the controls are bound..

I 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.

I have created many datasetsets in many projects in a solution. In each case the datatables reference a named data conection such as laptop_rick.intPricing.dbo. In that connection I point to the server, etc.. I should point out that in the code I connect to an entire different db server and this is all setup at runtime, this is strictly an IDE issue. Now I have moved the development server. Now of course when they try to connect to the server during development of the datasets it complains that it can't find the server. No problem just open the defined data connection and change the server name.
The problem is that I can't seem to get the dataset to recognize that it needs to rebuild that information in the xsd file. I look in the file and there are still references to the old server. If I change the connection definition in the xsd and rebuild all is fine but I don;t want to have to do that for each every dataset. It seems that although the dataset recognizes the name of the named data connection instead looking for that it embeds the details of the connection into the dataset xsd file.

I am working on a media player, and I would like to setup a local playlist feature. I am using a single ListBox and its "Display-" and "Value-Member" properties. The display is the song's Artist and Name, and the value is the song's file path (i.e 'C:UsersUSERMusicetc.').To write the file path to the .txt file, I believe I can use the following code:[code]

I am trying to do is fill out a form with certain info, put the info into an array, and write it to a listbox using loops, arrays, and maybe a function if I need one. This is for VB2010 and here is what I have so far... I think there are ways to make it shorter but I cannot figure it out.... maybe just brain dead from all the coffee I have been drinking!

how to correlate info from a textbox based on a listbox item selection. For example the user will select an item from the listbox, enter say the length of a song in the textbox say 2:00 for song #1, select say song #2, enter the song time for that song say 3:00, click on song #1 again and have the same textbox display the length of that song and be able to do that until there are no more songs on the list.

im calling a bunch of different propertys named K0 to K6, im using a string to check which one i need to access, this is damn messy, how can i do it in a more clean way? Im convinced that strings are not the way to go so please give me a comment to get in the right direction.
Dim tempAntDec As Integer
Select Case wd.MClass
Case "K0" [code]....
I would like to call this in some other way like, this.. or dont know but i feel like there is a better way to handle this?
tempAntDec = wd.allMeasUnc.KValue.antDec

In my classic asp app, I have a markup page with a bunch of checkboxes. The checkbox control ID is bscv.Once a user checks a box and clicks submit, the value is processed on the next page called next.asp.Based on the value of the checked box, I display the correct dropdown.I use the following code on next.asp to display the correct dropdown.
If bsvc = "master" Then
' only master was checked
' "If the user checks only master checkbox, ...txtmaster with 2 options... is displayed."
%>
<select id="txtmaster" name="txtmaster">
<option value="">-Select a service-</option>
<option value="1">1</option>

I need to modify a xml file (actually a .rdlc report file) and add some nodes which have a lot of children nodes (and those children nodes again have children nodes). Actually they are almost the same strucutre, like this one:
<TablixRow>
<Height>0.23622in</Height>
<TablixCells>
[Code].....
and it will add my specified NS. (like I said, XElement.Parse(string) won't add it) So now I can construct the correct node. For my second problem I still can't figure out: I can't navigate to the target node by using the element name since it won't search for correct NS.

I am developing an automation tool which is reading the file path from an Excel workbook and after launching the application I am firing print job using SendKeys.SendWait() for Ctrl+P and Enter key. Now the Problem is, I am facing synchronization issue for launching the application and handling the print procedure keys.Sometimes Applications are launching little late(like Excel and MsWord files), so at that time I am not able to find till how long I have to wait for a successful launch of the Application. Anybody have any Idea how to check this waiting time till how long I should wait to fire CTRL+P and then after getting PrintDialog ENTER button ?

I've got a listview with a bunch of items which all use checkboxes. Each time an item is checked or unchecked I want to save the selection. Whilst saving/loading the selection is not an issue, I can't seem to find an event which triggers AFTER the checked item has been changed. For example, the ItemChecked event will fire when an item has been checked or unchecked but the event will give it's checked status BEFORE it was changed. I've had to resort to saving the list when it loses focus but this isn't ideal.

If I need to read a bunch of items from the Registry, the following gets tiring fast:
Dim item1, item2 As String
item1 = My.Computer.Registry.GetValue(KeyValue, "item1", Nothing)
item2 = My.Computer.Registry.GetValue(KeyValue, "item2", Nothing)
Is there a smarter, more compact way to do this?
I was thinking of using a dictionary object, but it doesn't work as planned:
Dim dict As New Dictionary(Of String, String)
dict.Add("item1", Nothing)
dict.Add("item2", Nothing)

I have a flowlayoutpanel, and a bunch of controls inside it.
I would like to actually SORT the controls, depending on some values.
For Example:
The FlowLayoutPanel has 4 Controls:
Each control has: Name (string), Maker (string) and Rated (integer) values.
So what I thought of was:
Dim
s As
New
SortedList

I am creating an instance of a Generic List collection and I am surprised to find that I can't add more than one value to it at a time. I was thinking there was going to be something like what you can do with arrays, where you can add a group of values to it at creation. I saw the AddRange method, but that seems to add another collection to the end of this collection, which is not what I want. So my code is:
vb
Dim MyList as New List(Of String)
MyList.Add("John")
MyList.Add("Bob")
